Background: Effective and reliable communication is the cornerstone of safe communication in the operating room (OR). The OR is one of the most dynamic places in the hospital where multiple disciplines must work together in perfect harmony to ultimately improve patient outcomes. To create familiarity by name regarding constantly changing team members, individual name tagging was implemented in the OR. Methods: We analysed the impact of name tagging in the OR in a proof-of-concept study. Name tags (either first or last name), coloured according to the specific department, have been placed on the cap since March 13, 2023. On May 26, 2023, a total of 440 anaesthesiologists, general, visceral, and trauma surgeons, nurses, and service staff were invited to answer an evaluation questionnaire of nine questions. The survey period ended on August 7, 2023. 101 people answered the query which, among other things, asked for overall ratings, compliance, evaluation of specific items as well as positive and negative aspects. Statistical analyses were performed using R. Results: Most of the interviewed staff rated the implementation of name tagging positively (median=3.4; scale from 1-5, 1=bad, 5=good). The greatest benefit was seen in communication in general, direct contact with colleagues, and delegation of tasks. Most of the staff (>90 %) adhered to the new project and used it regularly. Negative aspects mentioned included potential loss of sterility, loss of respectability, and environmental impact. Potential for improvement was seen in the bonding method of attachment or in the implementation. Conclusion: Individual name tagging in the OR can improve interprofessional communication and is one tool to enhance patient safety by decreasing reservations or intimidations towards previously unknown colleagues. More studies are required to determine long-term effects on patient safety, outcome, or employee satisfaction. [ABSTRACT FROM AUTHOR]

Background: With the introduction of robot-assisted surgery, the role and responsibility of the operating room nurses have been expanded. The surgical team for robotic-assisted surgery depends on the ability of the operating room nurses to operate and handle the robotic system before, during, and after procedures. However, operating room nurses must acquire the necessary competencies for robotic-assisted surgery. Method: We performed a systematic review using the databases MEDLINE and EMBASE to review the evidence on educating and training operating room nurses in robot-assisted surgery. Studies describing operating room nurses' training and team-training with operating room nurses for robot-assisted surgery were included. The Medical Education Research Study Quality Instrument (MERSQI) and the Newcastle–Ottawa Scale-Education (NOS-E) were used to evaluate the quality of the included studies. Results: We identified 3351 potential studies and included 16 in the final synthesis. Nine studies focused on team-training in robot-assisted surgery: four focused solely on training for operating room nurses, and only three on operating room nurses as first assistants in robot-assisted surgery. Most studies examined team-training in RAS, including OR nurses, focused on emergency situations and conversion to an open procedure. Only a few studies addressed other competencies relevant to OR nurses in RAS. No randomized controlled trials were identified. Only a few studies used pre- and post-testing, and only one examined clinical outcomes. The quality assessment of the included studies was moderate to low, with a median MERSQI score of 10.3 and a median NOS-E score of 2. Conclusion: There is sparse research on the education of operating room nurses in robot-assisted surgery, and the literature emphasizes the training of surgeons. More research is needed to develop evidence-based training for operating room nurses in robot-assisted surgery. [ABSTRACT FROM AUTHOR]

Objective: To understand views of staff in relation to attitudes, enablers, and barriers to implementation of environmentally sustainable surgery in operating theatres. This will ultimately help in the goal of successfully implementing more sustainable theatres. Background: Global health care sectors are responsible for 4.4% of greenhouse gas emissions. Surgical operating theatres are resource intensive areas and improvements will be important to meet Net-Zero carbon emissions within health care. Methods: Three databases were searched (Web of Science, Ovid, and PubMed), last checked January 2024. We included original manuscripts evaluating staff views regarding sustainable operating theatres. The Mixed Methods Appraisal Tool was used for quality appraisal and data analysed using thematic synthesis. Results: A total of 2933 articles were screened and 14 fulfilled inclusion criteria, using qualitative (1), quantitative (2), and mixed methods (11). Studies were undertaken in a variety of clinical (Department of Anaesthesia, Surgery, Otolaryngology, Obstetrics and Gynaecology and Ophthalmology) and geographical settings (Australia, Canada, France, Germany, New Zealand, United States, United Kingdom, and Ireland). Across studies there was a lack of evidence exploring enablers to implementation, but barriers mainly related to the following themes: education and awareness, leadership, resistance to change, facilities and equipment, time, and incentive. Conclusions: This systematic review identified attitudes and barriers perceived by clinicians towards improving environmental sustainability within operating theatres, which may inform future strategy towards sustainable surgery. Most studies used a survey-design, whereas use of interviews may provide deeper insights. Future work should be extended to wider stakeholders influencing operating theatres. In addition, implementation studies should be carried out to examine whether barriers do change in practice. [ABSTRACT FROM AUTHOR]

Anesthesiologists are perioperative leaders of patient and health care team safety. The anesthesiologist needs to remain vigilant in the perioperative setting and while caring for patients. The ability to navigate increased noise levels, distractions, and hazards is crucial for maintaining a safe environment. While some noise, such as music, can have benefits, overall noise levels can distract from patient care and have adverse effects on patient care and intraoperative staff. This study provides an overview of noise, distractions, and hazards in the perioperative environment. [ABSTRACT FROM AUTHOR]

Background: Operating room nurses are critical in upholding high ethical standards in fast-paced and high-stakes environment to guarantee the safety and well-being of patients undergoing surgery to resolve life-threatening situations. A deeper understanding of ethical issues in the Operating Room helps tailor interventions and policies to address real-world challenges, enhance patient care, and assist healthcare professionals. Objective: This study explored the lived experiences of Operating Room nurses regarding ethical issues in Operating Room at Adama Hospital Medical College in Adama, Ethiopia, in 2022. Method: A qualitative study using the hermeneutic phenomenological method was conducted at Adama Hospital Medical College from March 15, 2022 to April 15, 2022. Eighteen nurses were selected as participants using maximum variation purposive sampling. The data was collected through semi-structured in-depth interviews. The data was then imported into Atlas Ti 8 software to be coded and categorized. To ensure trustworthiness, the basic principles such as credibility, confirmability, dependability, and transferability were applied. Data analysis was conducted based on the Van Manen (2016) method and the results were summarized using thematic analysis. Results: The study revealed two main themes and ten sub-themes regarding ethical issues faced by operating room nurses. The main themes were issues related with safeguarding patient dignity and issues of Staff Professionalism and Respectful Interaction. Conclusion: Upholding ethical principles and standards are critical for improving patient care and fostering positive relationships. Concepts such as Preoperative communication, ethical considerations in emergency surgeries, privacy, cultural and gender sensitivity, staff rapport, personal and professional competence, bearing responsibility, caring for patients with justice, and sterilization standards and aseptic techniques are crucial for participants. Addressing ethical concerns and ensuring compliance will enhance healthcare delivery in perioperative settings. [ABSTRACT FROM AUTHOR]

Background: In clinical settings, continuous changes lead to increased professional stress, affecting the quality of life of nurses. Some complementary interventions may influence the improvement of the quality of life. This study aimed to determine the effect of Benson's relaxation technique on the operating room nurses' quality of life. Methods: In this clinical trial, 180 operating room nurses were randomly allocated to two groups: intervention (Benson's relaxation technique) and control (routine activity). The study was conducted from December 2021 to March 2022 in hospitals affiliated with Shiraz University of Medical Sciences. Benson's relaxation technique was performed twice daily by the intervention group for 8 weeks. Quality of life was measured before and after the intervention using the SF-36 questionnaire. Data were analyzed using SPSS version 21 software, with a significance level set at a P < 0.05. Results: After the intervention, the results showed that Benson's relaxation technique led to an increase in the quality of life in the intervention group (P < 0.0001). In terms of quality-of-life dimensions, significant improvements were observed in the intervention group in the domains of physical problems (P < 0.05), emotional problems (P < 0.05), general health (P < 0.05), pain (P < 0.0001), and social functioning (P < 0.05). However, no significant differences were found in the dimensions of physical functioning, energy, and emotional well-being. Conclusions: Benson's relaxation technique can serve as a complementary method to improve various dimensions of the operating room nurses' quality of life. Trial Registration Number: IRCT20211002052650N1 with the Clinical Trial Registry (26.10.2022). [ABSTRACT FROM AUTHOR]

BACKGROUND: The conventional round suture needle poses a significant risk of needle stick injuries among surgical physicians, identified as a global occupational hazard by the World Health Organization, increasing hospital costs and exposure to bloodborne pathogens. While novel blunt suture needles have shown promise in reducing these risks, their adoption is limited domestically, prompting a study to compare their efficacy against traditional sharp needles in reducing needle stick injuries among surgical physicians. OBJECTIVE: To investigate suture needle stick injuries among surgical doctors during operations and assess the application effectiveness of a novel blunt suture needle. METHODS: A total of 106 surgical department physicians from March 2021 to February 2023 participated in the study. After completing a questionnaire survey on suture needle injuries during surgery, the participants were divided into two groups. Over a 6-month intervention period, the control group used regular round needles while the study group utilized novel blunt suture needles. Subsequently, suture needle injury incidence rates and economic hygiene benefits were compared between the two groups. RESULTS: The suture needle injury questionnaire survey showed that over the past 6 months, among 106 surgical department physicians, 20 needle stick injuries occurred, yielding an incidence rate of 18.87%. The highest incidence (65.00%) was during suturing incisions longer than 10 cm, primarily when visibility was poor (70.00%). Surgeons linked most injuries (60.00%) to prolonged surgical duration causing fatigue. Although 85.00% detected injuries within 1 minute, only 40.00% were reported, often due to perceived reporting complexity. Following intervention, the study group had significantly fewer injuries per surgery and lower occupational exposure costs compared to the control group (p < 0.05). CONCLUSION: Surgical department physicians commonly sustain suture needle injuries while suturing incisions of 5–10 cm length under poor visibility, exacerbated by prolonged surgical duration. Despite detecting most injuries within 1 minute, only 40% are reported. The implementation of novel blunt suture needles significantly decreases injury rates, resulting in reduced occupational exposure costs and favorable safety and economic hygiene outcomes.

Objectives Demand for rapid coagulation testing for massive transfusion events led to development of an emergency hemorrhage panel (EHP; hemoglobin, platelet count, prothrombin time/international normalized ratio, and fibrinogen), with laboratory turnaround time (TAT) of less than 20 minutes. Ten years on, we asked if current laboratory practices were meeting that TAT goal and differences were evident in TAT between the 2 major institutions in our system. Methods We identified EHPs ordered at our 2 largest hospitals, February 2, 2021, to July 17, 2022, comparing order to specimen draw time, specimen draw to specimen received time, laboratory analytic time, and total TAT results from emergency department and operating room. Site 1 houses a level I trauma center; site 2 includes tertiary care, transplant, and obstetrics services. Results In total, 1137 EHPs were recorded in our study period. Laboratory TAT was significantly faster at site 1 (~14 vs ~27 minutes, P <.01). Average laboratory TAT was under 20 minutes at site 1 but only for 50% of specimens at site 2. Outlier specimens were collection delays at site 1 and specimen processing delays at site 2. Conclusions The EHP can be performed as rapidly as described. However, compromises in laboratory location, available personnel, and processing differences can degrade performance. [ABSTRACT FROM AUTHOR]

One important factor for the prevention of surgical site infections is ultraclean air in the operating room (OR). Still, the direct sterilization potential of most technologies, especially in a dynamic clinical setting, is not well understood. We aimed to determine and compare the microbial presence from the inlet and outlet flow of a filtration unit with crystalline ultraviolet-C (C-UVC) light. A prospective study was conducted at a single institution, where primary total joint arthroplasty and spine surgeries were performed. The OR was fitted with a positive ventilation system. In addition, a filtration unit with a C-UVC sterilizing light was placed in the OR. The inlet and outlet air flows were swabbed simultaneously and compared. Swabs were processed for culture and next-generation sequencing. The mean length of the surgical procedures sampled was 68 ± 13 minutes. Overall, 19 out of 200 (9.5%) swabs isolated microorganisms. Inlet air swabs were positive at a higher rate (16 versus 3%; P <.01) compared to the outlet air swabs. A wide variety of Gram-positive, Gram-negative, and anaerobic bacteria were isolated, but fungi were only recovered from inlet air swabs. The detection of microorganisms was also higher when more door openings were performed (32.5 ± 7.1 versus 27.9 ± 5.6; P <.01). Air swabs mainly isolated microorganisms from the inlet flow to the filtration unit with a C-UVC light. The sterilizing unit counteracted factors affecting the air quality in the OR, namely door openings, surgical personnel, and tissue combustion. [ABSTRACT FROM AUTHOR]

Objective Patients and Methods Results Conclusions This study sought to compare the risks and outcomes associated with category I cesarean section procedures performed in the delivery room versus those performed in the operating room.The analysis included 126 singleton pregnant women who underwent inpatient delivery at the Second People's Hospital of Nanning between January 2021 and May 2024. Following propensity score matching, 21 cases were in the delivery room group, and 105 cases were in the operating room group. Parameters under investigation encompassed decision‐to‐delivery interval, incision‐to‐delivery interval, surgical duration, intraoperative blood loss, postoperative antibiotic duration, postoperative hospital stay length, postoperative fever incidence, adverse neonatal outcomes, and blood routine parameters.The decision‐to‐delivery interval was significantly shorter in the delivery room group than in the operating room group. Conversely, the delivery room group exhibited longer surgical durations, higher blood loss, prolonged postoperative antibiotic usage, extended hospital stays, and elevated white blood cell counts with statistical significance (p < 0.05). Nevertheless, no notable variations were observed between the groups in maternal and neonatal outcome indicators, such as adverse neonatal outcomes and postoperative fever rates.The outcomes suggest that the delivery room group showed increased risks compared with the operating room group, potentially indicating heightened vulnerabilities to bleeding and infection. Hence, it is advisable for patients to undergo surgery in the operating room unless the delivery room is equipped with sterile surgical facilities or in cases of urgent necessity.

Introduction: Operating room (OR) efficiency is a key factor in determining surgical healthcare costs. To enable targeted changes for improving OR efficiency, a comprehensive quantification of the underlying sources of variability contributing to OR efficiency is needed. Previous literature has focused on select stages of the OR process or on aggregate process times influencing efficiency. This study proposes to analyze the OR process in more fine-grained stages to better localize and quantify the impact of important factors. Methods: Data spanning from 2019-2023 were obtained from a surgery center at a large academic hospital. Linear mixed models were developed to quantify the sources of variability in the OR process. The primary factors analyzed in this study included the primary surgeon, responsible anesthesia provider, primary circulating nurse, and procedure type. The OR process was segmented into eight stages that quantify eight process times, e.g., procedure duration and procedure start time delay. Model selection was performed to identify the key factors in each stage and to quantify variability. Results: Procedure type accounted for the most variability in three process times and for 44.2% and 45.5% of variability, respectively, in procedure duration and OR time (defined as the total time the patient spent in the OR). Primary surgeon, however, accounted for the most variability in five of the eight process times and accounted for as much as 21.1% of variability. The primary circulating nurse was also found to be significant for all eight process times. Discussion: The key findings of this study include the following. (1) It is crucial to segment the OR process into smaller, more homogeneous stages to more accurately assess the underlying sources of variability. (2) Variability in the aggregate quantity of OR time appears to mostly reflect the variability in procedure duration, which is a subinterval of OR time. (3) Primary surgeon has a larger effect on OR efficiency than previously reported in the literature and is an important factor throughout the entire OR process. (4) Primary circulating nurse is significant for all stages of the OR process, albeit their effect is small. [ABSTRACT FROM AUTHOR]

Background: The operating room is a high-risk environment where proper patient positioning is crucial for minimizing injury and ensuring optimal access to surgical sites. This process requires effective collaboration among surgical team members, particularly operating room nurses who play a vital role in patient safety. Despite advancements in technology, challenges such as pressure injuries persist, with a significant incidence rate. Video-based training (VBT) emerges as a promising educational tool, enhancing knowledge retention and fostering a learner-centered approach. This study aims to evaluate the impact of VBT on adherence to surgical positioning standards, highlighting its potential to improve safety protocols in the operating room. Methods: In this clinical trial, 62 qualified operating room nurses (50 women, 12 men, average age: 28.90 ± 3.75 years) were randomly divided into control and intervention group (n = 31 in each group). The control group only received positioning recommendations, but in the intervention group, in addition to the recommendations, video-based surgical positioning training was performed for 1 month, at least 3 times a week. The performance of nurses in both groups was evaluated through a researcher-made checklist at baseline and post-intervention. Results: Based on findings, there was no significant difference between the two groups in compliance with surgical positioning standards at baseline (p = 0.07). However, after the intervention, compliance scores significantly improved in the VBT group compared to the control group (p < 0.001). The VBT group showed a mean improvement of 62.12 points, while the control group improved by 10.77 points (p < 0.001). Conclusions: This preliminary study demonstrated a notable improvement in compliance with surgical positioning standards among operating room nurses following VBT intervention. Despite the promising results, the small sample size and preliminary nature of the research necessitate further studies to confirm these findings and assess long-term outcomes. These initial insights highlight the potential of innovative training methods in enhancing surgical practices. [ABSTRACT FROM AUTHOR]

Conclusion: The trend in the field lies in "anaesthetic gas", "blood borne pathogen", "radiation" and "aerosol", while "surgical smoke" and "occupational safety" are the recently researching hot spots in this study. Accurate recognize and effective protection are always essential subjects for researchers. [ABSTRACT FROM AUTHOR]

Objectives: The study aimed to fill the knowledge gap about how operating room (OR) design could reduce orthopedic surgery duration and contribute to surgical care safety and efficiency. Background: Long surgery duration may lead to delays and cancellations of surgeries, deteriorated patient experiences, postoperative complications, and waste of healthcare resources. The OR physical environment may contribute to the reduction of surgery duration by minimizing workflow disruptions and personnel movements during surgeries. Methods: Unobtrusive observations were conducted of 70 unilateral total knee or hip replacement surgeries in two differently designed ORs at a community hospital in the United States. A set of computer-based forms adapted from recent research was used to measure the surgery duration, environment-related disruptions, and ambulatory movements involving circulators. Potential confounding factors like surgery type were controlled in statistical analyses. Results: Significantly shorter surgery durations were recorded in the larger OR with more clearances on both sides of the operating table, a wider door located on the sidewall, more cabinets, and more clearance between the circulator workstation and the sterile field (p =.019). The better-designed OR was also associated with less frequent disruptions and fewer movements per case (p <.001). Significant correlations existed between surgery duration, the number of disruptions, and the number of movements (r s =.576–.700, p s <.001). Conclusions: The study demonstrated the important role of OR physical environment in supporting the safe and efficient delivery of surgical care, which should be further enhanced through research and design innovations.

An operating room is a healthcare facility used to perform surgical operations on a patient. The OR demands high-air cleanliness and sterile conditions to reduce the risk of patients contracting surgical site infections. However, previous research stated that noticeable particle concentrations were identified near the surgery area. This scenario could elevate the tendency of particles to settle on the patient's wound and subsequently cause SSIs. Therefore, this study examines the effectiveness of innovative localised exhaust and air curtains in reducing the number of particles settling on the patient. An OR model was constructed using computer-aided design (CAD), while the airflow and particle simulation were performed using computational fluid dynamics (CFD). The reliability of the present work was verified and validated using established data before the case study. A Re-Normalisation Group (RNG) k–ε model based on the Eulerian approach was used to simulate the airflow. In contrast, a discrete phase model (DPM) based on the Lagrangian approach was used to simulate the airborne particle dispersion. Results showed that the activation of the localised exhaust located on the two sides of the operating table could reduce the total particle settlement on the patient by 26% when compared to the baseline ventilation system. The installation of an additional air curtain showed the best performance in terms of reducing the particle settlement, followed by the installation of both an additional air curtain and a localised exhaust outlet. The particle concentration settled on a patient showed a positive relationship with the body surface area, which is expressed by equation y = 0.1088x + 0.2528 with a coefficient of determination, R2 value = 0.8764. This study suggests that adopting localised exhaust and air curtain systems in ORs could greatly improve infection control, enhance patient safety and elevate healthcare quality and outcomes.

A validated computational fluid dynamic (CFD) model was developed to conduct a detailed examination of particle distribution within a burn patient ward. The indoor airflow was simulated using an RNG k–epsilon turbulence model, and particle dispersion was tracked employing a discrete phase model (DPM) that utilizes the Lagrangian framework. The primary objective is to assess the impact of a thermal-guided mobile air supply (MAS) unit, used in conjunction with an air curtain jet and localized exhaust grilles, on controlling particle dispersion. The focus on burn patient wards is critical, given the heightened vulnerability of burn patients to environmental contaminants, coupled with their impaired thermoregulatory and fluid balance capabilities. By integrating temperature control through the MAS unit, this study explores a novel approach to maintaining a sterile environment, achieving 0 BCP/m3 within the laminar airflow region around patients. The analysis reveals that the MAS unit significantly reduces particle penetration into the patient's protective zone by 82% relative to the baseline scenario without the activation of MAS unit. The thermal-guided MAS unit also effectively maintains ambient air temperatures within the optimal 21–24 °C range for burn patient recovery zone. However, the study also uncovers a temperature distribution around healthcare workers who do not meet satisfactory conditions, indicating areas for further improvement. In addition, the particle dispersion outside the protective zone was exacerbated when the MAS unit was activated, which demonstrated its contradictory effect. This underscores the importance of selecting optimal operating temperatures and configurations in clinical practice, emphasizing the need for extensive clinical testing and verification of the MAS device in varied room layouts and ventilation schemes. This research contributes significantly to the field by focusing on an underexplored area of patient care technology during critical times, providing insights into the efficacy of thermal-guided MAS units in enhancing environmental control in burn patient wards.

Background: Undesirable injuries during the intraoperative period, such as pressure injuries caused by improper positioning, medical devices, or adhesive tapes, can lead to patient harm and decreased satisfaction. This study aims to identify the risk factors of pressure injuries during the intraoperative period and the characteristics of these injuries. Methods: A retrospective case‑control study was conducted at King Khaled University Hospital in Riyadh, Saudi Arabia. Data were collected from the hospital incident reporting system and electronic medical records for incidents reported from January 1, 2022 to December 31, 2022. Inclusion criteria consisted of all patients with a reported pressure injury, including pressure ulcers, medical adhesive‑related skin injuries, or medical device‑related pressure injuries, occurring at least once during surgery. Results: Among the 113 patients, 57 (50.44%) had intraoperative pressure injuries (cases), while 56 (49.56%) did not (controls). The most common locations for pressure injuries were the lips (33.33%). Most of these injuries were classified as Medical Adhesive‑Related Skin Injury (61.40%). Stage 1 injuries were observed in 47 cases (82.46%), while Stage 2 injuries were observed in 10 cases (17.54%). Duration of surgery and device tightness were identified as significant risk factors (P < 0.001). Conclusion: This case‑control study identified the duration of surgery and device tightness as significant risk factors for intraoperative pressure injuries. The findings emphasize the importance of implementing evidence‑based prevention strategies. Healthcare professionals should prioritize staff education and training, while future research should focus on conducting prospective, multicenter studies and developing risk assessment tools and innovative medical devices.

This study was conducted to analyze the findings of qualitative studies about nursing students' experiences with operating room (OR) practices. There is a need to conduct metasynthesis studies to highlight the overarching dimensions of nursing students' experiences in the OR learning environment, identify and summarize key elements, draw attention to the professional implications of the experience, and then help define the future research agenda. This original study is the first metasynthesis of qualitative studies focusing on nursing students' OR practice experiences. A qualitative metasynthesis. This metasynthesis study was based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement and registered with PROSPERO (International prospective register of systematic reviews) (CRD42021252129). This metasynthesis consists of qualitative studies that included themes, were conducted with nursing students with OR experience, and were published in English between December 2000 and June 2022. Data were analyzed using the two-step metasynthesis procedures proposed by Sandelowski and Barroso. This metasynthesis study was carried out by analyzing 12 qualitative studies that met the inclusion criteria, reflected the results of a total of 244 nursing students, and were conducted in 7 different countries. As a result of the analysis of the studies, two main themes and seven subthemes were determined about the OR experiences of nursing students. The main themes of the study included (1) the OR environment and (2) professionalism and career choices. The synthesis of studies in this research revealed nursing students' OR experiences and provided evidence about the association between these experiences and their professionalism and career goals. The research drew attention to the limitations and facilitators of the OR learning environment for nursing students and provided guidance for a positive interactive learning environment.

To describe the development and implementation of a comprehensive in situ simulation-based curriculum for anesthesia residents. This is a prospective study. This study was conducted at a university hospital. This single-center prospective study included all 53 anesthesia residents enrolled in the anesthesia residency program. Introduction of a routine, high-fidelity, in situ simulation program that incorporates short sessions to train residents in the necessary skill sets and decision-making processes required in the operating room. Our team conducted 182 individual 15-minute simulation sessions over 3 months during regular working hours. All 53 residents in our program actively participated in the simulations. Most residents engaged in at least 3 sessions, with an average participation rate of 3.4 per resident (range, 1–6 sessions). Residents completed an online anonymous survey, with a response rate of 71.7% (38 of 53 residents) over the 3-month period. The survey aimed to assess their overall impression and perceived contribution of this project to their training. Our proposed teaching method can bridge the gap in resident training and enhance their critical reasoning to manage diverse clinical situations they may not experience during their residency.

Clinical care pathways help guide and provide structure to clinicians and providers to improve healthcare delivery and quality. The Quality Improvement and Patient Safety Committee (QIPS) of the American Society for Metabolic and Bariatric Surgery (ASMBS) has previously published care pathways for the performance of laparoscopic sleeve gastrectomy (LSG) and pre-operative care of patients undergoing Roux-en-Y gastric bypass (RYGB). This current RYGB care pathway was created to address intraoperative care, defined as care occurring on the day of surgery from the preoperative holding area, through the operating room, and into the postanesthesia care unit (PACU). PubMed queries were performed from January 2001 to December 2019 and reviewed according to Level of Evidence regarding specific key questions developed by the committee. Evidence-based recommendations are made for care of patients undergoing RYGB including the pre-operative holding area, intra-operative management and performance of RYGB, and concurrent procedures. This document may provide guidance based on recent evidence to bariatric surgeons and providers for the intra-operative care for minimally invasive RYGB. [ABSTRACT FROM AUTHOR]

Background A surgeon's daily performance may be affected by operating room organizational factors, potentially impacting patient outcomes. The aim of this study was to investigate the link between a surgeon's exposure to delays in starting scheduled operations and patient outcomes. Methods A prospective observational study was conducted from 1 November 2020 to 31 December 2021, across 14 surgical departments in four university hospitals, covering various surgical disciplines. All elective surgeries by 45 attending surgeons were analysed, assessing delays in starting operations and inter-procedural wait times exceeding 1 or 2 h. The primary outcome was major adverse events within 30 days post-surgery. Mixed-effect logistic regression accounted for operation clustering within surgeons, estimating adjusted relative risks and outcome rate differences using marginal standardization. Results Among 8844 elective operations, 4.0% started more than 1 h late, associated with an increased rate of adverse events (21.6% versus 14.4%, P = 0.039). Waiting time surpassing 1 h between procedures occurred in 71.4% of operations and was also associated with a higher frequency of adverse events (13.9% versus 5.3%, P < 0.001). After adjustment, delayed operations were associated with an elevated risk of major adverse events (adjusted relative risk 1.37 (95% c.i. 1.06 to 1.85)). The standardized rate of major adverse events was 12.1%, compared with 8.9% (absolute difference of 3.3% (95% c.i. 0.6% to 5.6%)), when a surgeon experienced a delay in operating room scheduling or waiting time between two procedures exceeding 1 h, as opposed to not experiencing such delays. Conclusion A surgeon's exposure to delay before starting elective procedures was associated with an increased occurrence of major adverse events. Optimizing operating room turnover to prevent delayed operations and waiting time is critical for patient safety. [ABSTRACT FROM AUTHOR]

Background Noise in the operating room has been shown to distract the surgical team and to be associated with postoperative complications. It is, however, unclear whether complications after noisy operations are the result of objective or subjective surgical difficulty or the consequence of distraction of the operating room team by noise. Methods Noise level measurements were prospectively performed during operations in four Swiss hospitals. Objective difficulty for each operation was calculated based on surgical magnitude as suggested by the Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM), duration of operation and surgical approach. Subjective difficulty and distraction were evaluated by a questionnaire filled out by the operating room team members. Complications were assessed 30 days after surgery. Using regression analyses, the relationship between objective and subjective difficulty, distraction, intraoperative noise and postoperative complications was tested. Results Postoperative complications occurred after 121 (38%) of the 294 procedures included. Noise levels were significantly higher in operations that were objectively and subjectively more difficult (59.89 versus 58.35 dB(A), P < 0.001) and operations that resulted in postoperative complications (59.05 versus 58.77 dB(A), P = 0.004). Multivariable regression analyses revealed that subjective difficulty as reported by all members of the surgical team, but not distraction, was highly associated with noise and complications. Only objective surgical difficulty independently predicted noise and postoperative complications. Conclusion Noise in the operating room is a surrogate of surgical difficulty and thereby predicts postoperative complications. [ABSTRACT FROM AUTHOR]

Background/Objectives: Operating room (OR) efficiency is a critical factor in healthcare delivery, influenced by various components including surgical duration, room turnover, staff availability, and equipment preparation. Optimizing surgical start times through systematic strategies such as computational algorithms can significantly enhance OR utilization and management. This study aimed to improve OR efficiency by effectively managing and optimizing surgical start times using a computational algorithm designed to allocate resources more efficiently. Methods: A comparative analysis was conducted over two six-month periods from January to June 2023 and January to June 2024, with an improvement phase implemented between July and December 2023. Results: These measures encompassed training surgical personnel, strengthening the medical team, revising work procedures and hospital regulations, and the integration of a computational algorithm to better schedule and manage surgical interventions. Following the implementation of these comprehensive measures, enhanced management of surgical start times was observed. A statistically significant increase in surgical interventions between 8 and 10 a.m. was noted for the entire OR, rising from 28.65% to 32.13%. While OR occupancy between 8 and 12 a.m. increased from 63.91% to 73.30%, this difference was not statistically significant. However, a notable improvement in average occupancy between 9 and 11 a.m. was observed, rising from 87.53% to 98.07%. Conclusions: The introduction of computational algorithms significantly improved operating room efficiency, particularly in managing surgical start times. Additionally, team coordination improved as a result of more structured scheduling processes. The results indicate that effective management of surgical start times, especially when enhanced by computational algorithms, can positively impact OR utilization, particularly within specific time blocks.

Objective: One minute of operating room (OR) time costs $36 to 37. However, ORs are notoriously inefficient. There is growing literature on improving OR efficiency, but no formal review of this topic within otolaryngology has been performed. This study reviews and synthesizes the current literature on improving OR efficiency within otolaryngology. Data Sources: MEDLINE, EMBASE, Web of Science, CINAHL, Cochrane Library, preprints.org, and medRxiv were searched on November 4, 2022. Review Methods: Published English studies were included if they reported on metrics for improving OR efficiency within otolaryngology. There were no publication date restrictions. Articles were screened by 2 reviewers. Preferred Reporting Items for Systematic Reviews and Meta‐analysis reporting for scoping reviews was followed. Results: The search yielded 9316 no‐duplicate articles; 129 articles were included. Most of the studies reported on head and neck procedures (n = 52/129). The main tactics included surgical considerations: hemostatic devices, techniques, and team/simultaneous approaches; anesthetic considerations: local anesthetic and laryngeal mask airways; procedure location considerations: procedures outside of the OR and remote technologies; standardization: equipment, checklists, and personnel; scheduling considerations: use of machine learning for booking, considering patient/surgeon factors, and utilizing dedicated OR time/multidisciplinary teams for on‐call cases. Conclusion: The current literature brings to attention numerous strategies for improving OR efficiency within otolaryngology. Applying these strategies and implementing novel techniques to manage surgical cases may assist in offloading overloaded health care systems and improving access to care while facilitating patient safety and outcomes. Anticipated barriers to implementation include resistance to change, funding, and the current strain on health care systems and providers. [ABSTRACT FROM AUTHOR]

Objective: To explain the perceptions of the operating room staff about pressure ulcers through metaphors. Methods: A descriptive qualitative research design was used. In the study, it was aimed to reach the entire universe, not choosing a sample. A total of 83 operating room staff participated in the study which 45 of them were operating room nurses, 38 of them were anesthesia technicians. The data were collected face to face with the descriptive features form and semi-structured interview form created by the researchers. In the semi-structured interview form, the operating room workers were asked to complete the sentence “Pressure ulcer is like ... because ...”. The data were analyzed with the "content analysis" method, which is one of the qualitative analysis methods.Results: Operating room staff generated a total of 25 types of metaphors for the concept of pressure ulcers and expressed 83 opinions for them. The first five most mentioned metaphors by the operating room staff were icebergs, matryoshka, storm after a sunny day, swamp, garden care and cracked vase, respectively. 19 of these metaphors were repeated nine to two times, and six of them were repeated once.Conclusion: Metaphors can be used as a powerful research tool in understanding and revealing the cognitive images of operating room staff regarding the concept of pressure ulcers. This study gives clues about how operating room staff imagine the concept of pressure ulcer.

Abstract Background Operating room nurses are critical in upholding high ethical standards in fast-paced and high-stakes environment to guarantee the safety and well-being of patients undergoing surgery to resolve life-threatening situations. A deeper understanding of ethical issues in the Operating Room helps tailor interventions and policies to address real-world challenges, enhance patient care, and assist healthcare professionals. Objective This study explored the lived experiences of Operating Room nurses regarding ethical issues in Operating Room at Adama Hospital Medical College in Adama, Ethiopia, in 2022. Method A qualitative study using the hermeneutic phenomenological method was conducted at Adama Hospital Medical College from March 15, 2022 to April 15, 2022. Eighteen nurses were selected as participants using maximum variation purposive sampling. The data was collected through semi-structured in-depth interviews. The data was then imported into Atlas Ti 8 software to be coded and categorized. To ensure trustworthiness, the basic principles such as credibility, confirmability, dependability, and transferability were applied. Data analysis was conducted based on the Van Manen (2016) method and the results were summarized using thematic analysis. Results The study revealed two main themes and ten sub-themes regarding ethical issues faced by operating room nurses. The main themes were issues related with safeguarding patient dignity and issues of Staff Professionalism and Respectful Interaction. Conclusion Upholding ethical principles and standards are critical for improving patient care and fostering positive relationships. Concepts such as Preoperative communication, ethical considerations in emergency surgeries, privacy, cultural and gender sensitivity, staff rapport, personal and professional competence, bearing responsibility, caring for patients with justice, and sterilization standards and aseptic techniques are crucial for participants. Addressing ethical concerns and ensuring compliance will enhance healthcare delivery in perioperative settings.

Abstract Background In clinical settings, continuous changes lead to increased professional stress, affecting the quality of life of nurses. Some complementary interventions may influence the improvement of the quality of life. This study aimed to determine the effect of Benson’s relaxation technique on the operating room nurses’ quality of life. Methods In this clinical trial, 180 operating room nurses were randomly allocated to two groups: intervention (Benson’s relaxation technique) and control (routine activity). The study was conducted from December 2021 to March 2022 in hospitals affiliated with Shiraz University of Medical Sciences. Benson’s relaxation technique was performed twice daily by the intervention group for 8 weeks. Quality of life was measured before and after the intervention using the SF-36 questionnaire. Data were analyzed using SPSS version 21 software, with a significance level set at a P

Abstract Background The operating room environment demands high levels of teamwork and interprofessional collaboration, yet current training programs often lack sufficient opportunities to develop these essential skills. Few studies have explored the impact of Interprofessional Education (IPE) based on digital information technology in improving the collaboration and learning among newly enrolled medical staff in the operating room. Objectives This study aimed to design, implement, and evaluate a digital information technology-based IPE training program for newly enrolled medical staff in the operating room. The evaluation focused on the effects of the program on the participants’ expertise, operational knowledge, team communication skills, and application of these skills in clinical practice. Methods Sixty-eight newly enrolled medical staff from surgical departments in a tertiary hospital in Shanxi province were included in this study from January 2021 to December 2022. The participants engaged in an IPE training curriculum that utilized digital information technology, featuring courses and case studies specifically tailored to the operating room environment. Post-training assessments included evaluation of test scores of expertise course, evaluation of surgical simulation operations (operational knowledge and communication), and the International Interprofessional Collaboration Competency Attainment Survey (ICCAS). The effectiveness of the training was assessed by evaluating improvements in communication skills, application of practical knowledge, and teamwork in surgical contexts. Results Expertise course evaluation and reflection revealed that the new enrolled medical staff in the operating room had a deep understanding of the knowledge. At the same time, they are better able to understand and master the nursing mode in the process of different professional surgery, and said that they would like to cooperate with surgeon and anesthesiologist during the surgical operation. The score of the Interprofessional Collaborative Competency Attainment Survey (ICCAS) increased significantly (P

Abstract Background/Objective The act of surgery involves harming vulnerable patients with the intent that the results will improve their health and, ultimately, help the patients. Such activities will inevitably entail moral decisions, yet the ethics of surgery has only recently developed as a field of medical ethics. Within this field, it is striking how few accounts there are of actions within the operating room. The aim of this systematic review was to investigate how much of the scientific publications on surgical ethics focus on what take place inside the operating room and to explore the ethical issues included in the publications that focus on medical ethics in the operating room. Methods We conducted a systematic search of the Medline and Embase databases using a PICO model and the search terms “surgery”, “ethics” and “operating room”. Papers were included if they focused on doctors, entailed activities inside the operating room and contained some ethical analysis. Thematic synthesis was used for data extraction and analysis. Findings Fewer than 2% of the scientific publications on surgical ethics included activities inside the operating room. A total of 108 studies were included in the full-text analysis and reported according to the RESERVE guidelines. Eight content areas covered 2/3 of the included papers: DNR orders in the OR, overlapping surgery, donation of organs, broadcasting live surgery, video recordings in the OR, communication/teamwork, implementing new surgical technology, and denying blood to Jehovah’s Witness. Discussion/Conclusions This systematic review indicates that only a small fraction of scientific publications on the ethics of surgery focus on issues inside the operating room, accentuating the need for further research to close this gap. The ethical issues that repeatedly arose in the included papers included the meaning of patient autonomy inside the operating room, the consequences of technological advances in surgery, the balancing of legitimate interests, the dehumanising potential of the OR, and the strong notion of surgeon responsibility.

Background: Undesirable injuries during the intraoperative period, such as pressure injuries caused by improper positioning, medical devices, or adhesive tapes, can lead to patient harm and decreased satisfaction. This study aims to identify the risk factors of pressure injuries during the intraoperative period and the characteristics of these injuries. Methods: A retrospective case-control study was conducted at King Khaled University Hospital in Riyadh, Saudi Arabia. Data were collected from the hospital incident reporting system and electronic medical records for incidents reported from January 1, 2022 to December 31, 2022. Inclusion criteria consisted of all patients with a reported pressure injury, including pressure ulcers, medical adhesive-related skin injuries, or medical device-related pressure injuries, occurring at least once during surgery. Results: Among the 113 patients, 57 (50.44%) had intraoperative pressure injuries (cases), while 56 (49.56%) did not (controls). The most common locations for pressure injuries were the lips (33.33%). Most of these injuries were classified as Medical Adhesive-Related Skin Injury (61.40%). Stage 1 injuries were observed in 47 cases (82.46%), while Stage 2 injuries were observed in 10 cases (17.54%). Duration of surgery and device tightness were identified as significant risk factors (P < 0.001). Conclusion: This case-control study identified the duration of surgery and device tightness as significant risk factors for intraoperative pressure injuries. The findings emphasize the importance of implementing evidence-based prevention strategies. Healthcare professionals should prioritize staff education and training, while future research should focus on conducting prospective, multicenter studies and developing risk assessment tools and innovative medical devices.

Abstract Background The operating room is a high-risk environment where proper patient positioning is crucial for minimizing injury and ensuring optimal access to surgical sites. This process requires effective collaboration among surgical team members, particularly operating room nurses who play a vital role in patient safety. Despite advancements in technology, challenges such as pressure injuries persist, with a significant incidence rate. Video-based training (VBT) emerges as a promising educational tool, enhancing knowledge retention and fostering a learner-centered approach. This study aims to evaluate the impact of VBT on adherence to surgical positioning standards, highlighting its potential to improve safety protocols in the operating room. Methods In this clinical trial, 62 qualified operating room nurses (50 women, 12 men, average age: 28.90 ± 3.75 years) were randomly divided into control and intervention group (n = 31 in each group). The control group only received positioning recommendations, but in the intervention group, in addition to the recommendations, video-based surgical positioning training was performed for 1 month, at least 3 times a week. The performance of nurses in both groups was evaluated through a researcher-made checklist at baseline and post-intervention. Results Based on findings, there was no significant difference between the two groups in compliance with surgical positioning standards at baseline (p = 0.07). However, after the intervention, compliance scores significantly improved in the VBT group compared to the control group (p

Abstract Objective The purpose of this study is to identify and visualize from different perspectives the topic on occupational exposure in operating room (OEOR). Methods In the Web of Science Core Collection (WoSCC), all the half-century data were retrieved from January 1st, 1973 to December 31st, 2022. CiteSpace, VOSviewer and Excel 2019 were employed to analyze and visualize data, based on publications, countries, institutions, journals, authors, keywords. Result A total of 336 journal papers were found. The increase of publications virtually started in 1991, peaked in 2020 and has been slowing down ever since. USA played most significant part among all the 49 countries/regions, while Universidade Estadual Paulista out of 499 institutions published the most papers. International Archives of Occupational and Environmental Health bears the most documents and citations in all the 219 retrieved journals. There are 1847 authors found, among whom Hoerauf K is the most influential one. "Occupational exposure”, “nitrous oxide” and “operating room personnel” are the top 3 co-occurrences keywords. Conclusion The trend in the field lies in “anaesthetic gas”, “blood borne pathogen”, “radiation” and “aerosol”, while “surgical smoke” and “occupational safety” are the recently researching hot spots in this study. Accurate recognize and effective protection are always essential subjects for researchers.

Background : When applying lung-protective ventilation, fluid responsiveness cannot be predicted by pulse pressure variation (PPV) or stroke volume variation (SVV). Functional hemodynamic testing may help address this limitation. This study examined whether changes in dynamic indices such as PPV and SVV, induced by tidal volume challenge (TVC), can reliably predict fluid responsiveness in patients undergoing renal transplantation who receive lung-protective ventilation. Methods : This nonrandomized interventional study included renal transplant recipients with end-stage renal disease. Patients received ventilation with a 6 mL/kg tidal volume (TV), and the FloTrac system was attached for continuous hemodynamic monitoring. Participants were classified as responders or nonresponders based on whether fluid challenge increased the stroke volume index by more than 10%. Results : The analysis included 36 patients, of whom 19 (52.8%) were responders and 17 (47.2%) were nonresponders. Among responders, the mean ΔPPV6-8 (calculated as PPV at a TV of 8 mL/kg predicted body weight [PBW] minus that at 6 mL/kg PBW) was 3.32±0.75 and ΔSVV6-8 was 2.58±0.77, compared to 0.82±0.53 and 0.70±0.92 for nonresponders, respectively. ΔPPV6-8 exhibited an area under the curve (AUC) of 0.97 (95% confidence interval [CI], 0.93–1.00; P≤0.001), with an optimal cutoff value of 1.5, sensitivity of 94.7%, and specificity of 94.1%. ΔSVV6-8 displayed an AUC of 0.93 (95% CI, 0.84–1.00; P≤0.001) at the same cutoff value of 1.5, with a sensitivity of 94.7% and a specificity of 76.5%. Conclusion : s: TVC-induced changes in PPV and SVV are predictive of fluid responsiveness in renal transplant recipients who receive intraoperative lung-protective ventilation.

Abstract Background Operating rooms contribute to over 40% of hospital expenses, with a portion attributed to waste from single-use, sterile surgical supplies (SUSSS). This research aimed to determine the amount of cost wastage due to not using SUSSS during laparotomy procedures. Methods A descriptive-analytical investigation was conducted in two prominent teaching hospitals in Mashhad, Iran 2018. Seventy-seven laparotomy surgeries were scrutinized, documenting both used and unused disposable devices, with their respective costs being assessed. Data analysis was performed using SPSS version 16 software. Results The study revealed that during surgery in the operating rooms, waste of SUSSS averaged 5.9%. Betadine solution and sterile Gauze types were the top two contributors to resource wastage. Sterile Gauze types incurred the highest cost loss. The study found a significant correlation between cost wastage and surgeon experience (r = 0.296, P

Objective To evaluate the application of refined teaching mode in the teaching of nursing students in the operating room. Methods Totally 40 nursing students who participated in the internship between August 2021 and July 2022 were included as the control group. Another 40 nursing students who participated in the internship between August 2022 and July 2023 were included as the study group. The control received routine teaching mode in the surgical teaching. A clinical teaching group was established to generate refined teaching plan, and targeted teaching strategies were carried out in clinical teaching of nursing students in the study group. Teaching efficacy was measured by examination of theory knowledge and practice skills, and students’ feedback on the clinical teaching was analyzed retrospectivelyResults Scores of theory knowledge test and practice skills assessment in the study group were higher than those in the control group(P＜0. 01). Nursing students in the study group were more satisfied with clinical teaching method compare that in the control group(P＜0. 05). Conclusion Refined teaching mode places great emphasis on training students sense of details and standardization, and focus on individual needs and differentiated characteristics of nursing students. It can stimulate students' interest in learning and improve the efficacy of clinical teaching practice in the operating room.

Abstract Objective Pneumatic tourniquets are among the most essential equipment for controlling bleeding in orthopedic surgeries. However, incorrect application of pneumatic tourniquets is accompanied by many hazards and complications for patients. Evaluation of surgical teams’ use of pneumatic tourniquets and establishment of protocols can play an important role in improving patient safety, minimizing risks, and increasing the lifetime of this equipment. Accordingly, the present study was conducted to develop and assess the psychometric properties of a pneumatic tourniquet work standards scale. Methods The present study is a methodological work carried out in two stages. In the first stage, an initial version of the scale was developed based on existing research and panel reviews. In the second stage, the psychometric properties of the scale were tested in terms of face validity (measured qualitatively and quantitatively), content validity (measured qualitatively and quantitatively), item analysis, construct validity, and reliability (internal consistency and stability). Results The initial version of the scale consisted of 91 items. After several meetings of the research team, the number of items decreased to 81. In the course of face and content validity testing, 40 items were eliminated, leaving 41 items on the scale when it entered the construct validity testing stage. For evaluation of construct validity, a sample of 300 operating room nurses was recruited. The Exploratory Factor Analysis (EFA) results showed a structure supported by seven factors and 41 items. The reliability of the scale was confirmed by internal consistency analysis, with a good Cronbach’s alpha (0.85), and test–retest analysis, with good values of ICC (0.95). Conclusion The present instrument is a reliable and valid scale which fills the gap in assessment of surgical team members’ use of pneumatic tourniquets. The developed scale can be employed by researchers and managers of medical centers to identify hazards in applying pneumatic tourniquets and devise educational programs to eliminate or reduce the existing issues.

Abstract Background Delays in surgery start times can lead to poor patient outcomes and considerable increases in healthcare expenditures. This is especially true in developing countries that often face systemic inefficiencies, such as a shortage of operating rooms and trained surgical personnel. With substantial effects on patient outcomes, healthcare efficiency, and resource allocation, identifying delays in first-case elective surgery is a crucial area of research. Methods A multicenter observational study was conducted at three comprehensive and specialized hospitals in the Amhara region of Ethiopia from May 1 to October 30, 2023. The primary aim of the study was to determine the occurrence of late first-case start times, defined as a patient being in the operating room at or after the hospital’s incision time of 2:30 a.m. The secondary aim was to discover potential root causes of delayed first-case start times. All patients scheduled for elective surgery as the first case on the operating list throughout the study period were included in the study. Every emergency, day case, after-hours case, and canceled case was excluded. Results A total of 530 surgical patients were included during the study window from May 1 to October 1, 2023. Of these, 41.5% were general surgeries, 20.4% were gynecology and obstetrics surgeries, and 13.2% were orthopedic surgery procedures. Before the procedure started, nine (1.7%) of the participants had prolonged discussion with a member of the surgical team. Patients who arrived in the operating room waiting area at or after 2:30 a.m. were 2.5 times more likely to experience a first-case start time delay than those who arrived before or at 2:00 a.m. (AOR = 2.50; 95% CI: 1.13–5.14). Furthermore, participants with abnormal investigation results were 2.4 times more likely to have a late first-case start time (AOR = 2.41; 95% CI: 1.06, 5.50). Moreover, the odds of a late first-case start time were increased by 10.53 times with the surgeon being in the operating room at or after 2:30 a.m. (AOR = 10.53; 95% CI: 5.51, 20.11). Conclusion The research highlights a significant occurrence of delayed start times for the first elective surgical procedures. Therefore, directing attention to aspects such as ensuring patients and surgical teams arrive promptly (by or before 2:00 a.m.) and timely evaluation and communication of investigative findings before the scheduled surgery day could facilitate efforts to maximize operating room efficiency and enhance patient health outcomes.

Abstract Background Fatigue in surgical technologists is of paramount importance and is known as a priority because it can be regarded as a threat to the nurse’s health and patient’s safety. The fatigue level of healthcare workers can be affected by some factors, while the role of part of these factors is less known. This study aimed to determine the predictive role of resilience and the hospital ethical climate in the fatigue of surgical technologists working in operating rooms (ORs). Methods This is a cross-sectional study conducted on 217 surgical technologists working in ORs of hospitals affiliated with Shiraz University of Medical Sciences. Data were collected using Connor-Davidson’s Resilience scale, Olson’s Hospital Ethical Climate Survey, and the Multidimensional Fatigue Inventory, and then analyzed using Pearson’s correlation coefficient and multiple regression analysis. Results 87.1% and 12.9% of surgical technologists reported low and high fatigue, respectively. All fatigue subscales had significant and negative relationships with resilience (p

Introduction: Nowadays, Clinical courses are meticulously structured to give students essential opportunities to elevate their professional qualifications, so that the patients’ safety is protected and their conditions improve. Given the many challenges in the clinical environment of the operating room, this study was conducted to compare the impact of team-based and task-based learning methods in the clinical settings on the perceived competence of surgery and the quality of training from the operating room nursing students’ point of view∙Methods: This quasi-experimental study was conducted on fifty 5th semester operating room technology students at Hamadan University of Medical Sciences in 2023. In this study, studentswere selected using the convenience sampling method and placed in two educational groups (team-based and task-based) of 25 subjects using the matching method. After implementing thetraining process in the operating room setting, the data related to the study were collected using the valid questionnaires of perceived competence in surgery (Cronbach’s alpha=0.86) andquality of education (Cronbach’s alpha=0.94). Also, the data analysis was conducted at the descriptive and inferential (included independent t-test and analysis of covariance) statistics level using SPSS version 16 software. Results: Findings showed that the mean clinical training quality score was significantly higher in the team-based learning group than in the other group (P=0.014). Also, after the medianintervention, the perceived competence score of surgery was higher in the task-based learning group than in the team-based group, and the difference in the average change of the competence score between the two groups was statistically significant (P

This research aimed to determine the amount of cost wastage due to not using SUSSS during laparotomy procedures. Methods: A descriptive-analytical investigation was conducted in two prominent teaching hospitals in Mashhad, Iran 2018. Seventy-seven laparotomy surgeries were scrutinized, documenting both used and unused disposable devices, with their respective costs being assessed. Data analysis was performed using SPSS version 16 software. Results: The study revealed that during surgery in the operating rooms, waste of SUSSS averaged 5.9%. Betadine solution and sterile Gauze types were the top two contributors to resource wastage. Sterile Gauze types incurred the highest cost loss. The study found a significant correlation between cost wastage and surgeon experience (r = 0.296, P < 0.001) as well as surgery duration (r = 0.439, P < 0.001). Conclusion: Inadequate management of available and commonly used disposable supplies leads to increased hospital expenses. Enhancing the surgical team's knowledge of sterile surgical supplies usage and making thoughtful selections can play a vital role in curbing health costs by minimizing waste of SUSSS in the operating rooms.

Introduction: Numerous pedagogical practices ought to be contemplated for the acquisition of practical aptitudes imperative to postgraduate operating room nursing education. The employment of digital technologies has emerged as a strategic focus in higher education and learning paths exhibit potential as a digital approach in nursing education. Objective: This study aimed to investigate the experiences of postgraduate OR nursing students who underwent a blended learning approach, which combines digital learning paths with skills training, and to explore how this approach prepares students to attain specific learning outcomes during their internship period. Methods: This qualitative study employed a descriptive, exploratory design and utilized focus group interviews facilitated by an interview guide to gather qualitative data. A purposive sampling strategy was employed, and the collected data were analyzed using a systematic text condensation approach. Results: The analysis of the data revealed two main categories and five subgroups. The first category, "Blended learning serves as adequate preparation for internship," includes subgroups that highlight the advantages of diverse learning activities that aid in the development of a strong foundation in practical skills. The positive influence of peer collaboration fosters improved learning through social interaction, while the organization of the curriculum has a significant impact on students' learning experiences. The second category, "The importance of skills training and behaving in an operating theater context," consists of subgroups that emphasize the necessity of progressing from basic technical skills training to simulation pedagogy to ensure appropriate behavior in the operating room. Small group sizes, close monitoring, and assessment by educators contribute to effective learning. Conclusion: The integration of digital learning paths with skills training fosters a problem-solving approach and encourages active and collaborative learning. Skills training in small groups, timely feedback, and coordination among subject managers to handle the students' workload can create an optimal learning environment. [ABSTRACT FROM AUTHOR]

Introduction Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a temporizing hemorrhage control intervention, but its inevitable effect on time to operating room (OR) has not been assessed. The aim of our study is to assess the impact of undergoing REBOA before surgery (RBS) on time to definitive hemorrhage control surgery. Methods In this retrospective analysis of 2017–2021 ACS-TQIP database, all adult (≥18 years) patients who underwent emergency hemorrhage control laparotomy (≤4 hours of admission) and received early blood products (≤4 hours) were included, and patients with severe head injury (Head-abbreviated injury score > 2) were excluded. Patients were stratified into those who did (RBS) vs those who did not undergo REBOA before surgery (No-RBS). Primary outcome was time to laparotomy. Secondary outcomes were complications and mortality. Multivariable linear and binary logistic regression analyses were performed to identify the independent associations between RBS and outcomes. Results A total of 32,683 patients who underwent emergency laparotomy were identified (RBS: 342; No-RBS: 32,341). The mean age was 39 (16) years, 78% were male, mean SBP was 107 (34) mmHg, and the median injury severity score was 21 [14–29]. The median time to emergency hemorrhage control surgery was 50 [32–85] minutes. Overall complication rate was 16% and mortality was 19%. On univariate analysis, RBS group had longer time to surgery (RBS 56 [41–89] vs No-RBS 50 [32–85] minutes, P  < 0.001). On multivariable analysis, RBS was independently associated with a longer time to hemorrhage control surgery (β + 14.5 [95%CI 7.8–21.3], P  < 0.001), higher odds of complications (aOR = 1.72, 95%CI = 1.27–2.34, P  < 0.001), and mortality (aOR = 3.42, 95%CI = 2.57–4.55, P  < 0.001). Conclusion REBOA is independently associated with longer time to OR for hemorrhaging trauma patients with an average delay of 15 minutes.

Introduction Definitive management of non-compressible intra-abdominal hemorrhage (NCIAH) currently requires a surgeon and operating room capable of performing damage control surgery. In a wartime scenario or a geographically remote environment, these may not be readily available. In this study, we sought to test the safety of 2 emerging injectable hemostatic agents (CounterFlow and Fast Onset Abdominal Management, or FOAM, poloxamer component) versus normal saline control over a prolonged monitoring duration following administration by a non-surgical provider. Materials and Methods The Institutional Animal Care and Use Committee approved all research conducted in this study. We randomized male New Zealand white rabbits into 2 monitoring cohorts of 24 hours and 2 weeks. Each cohort contained 3 treatment groups (n  = 4 rabbits/group): CounterFlow, the testable poloxamer component of FOAM, and normal saline control. We injected each treatment intraperitoneally in the left lower abdominal quadrant. Doses were 15 mL/kg for CounterFlow, 6.3 mL/kg for the poloxamer component of FOAM, and 15 mL/kg for normal saline. We conducted all injections under isoflurane anesthesia monitored by trained veterinary staff. Animals were euthanized at each cohort end point, and a veterinary pathologist blinded to treatment type performed necropsy. The primary outcome was incidence of intra-abdominal adhesions at necropsy. Quantitatively, adhesions when present were graded by the veterinary pathologist on a 1 to 4 scale, where "1" represented adhesions involving from 1 to 25% of the examined abdomen, "2" represented from 26 to 50%, "3" represented from 51 to 75%, and "4" represented from 76 to 100%. Qualitatively, adhesions present were graded by degree ("1" = minimal, "2" = mild, "3" = moderate, and "4" = severe) and chronicity ("1" = acute, "2" = subacute, and "3" = chronic). We also drew d-dimer blood values and measured body weights for each animal. Statistical analysis included either repeated measures 2-way ANOVA or a mixed-effects model (in the case of missing data) with Geisser–Greenhouse correction. We adjusted multiple comparisons using Tukey statistical hypothesis tests. Results In the 2-week cohort, 3 CounterFlow animals showed adhesions judged to be "1" quantitatively. Qualitatively, 2 of these were assessed as "1" for degree of adhesions and the other demonstrated a "2." On the chronicity of adhesions scale, 1 animal demonstrated a "2" and 2 demonstrated a "3." No animals in other groups (FOAM and control) demonstrated adhesions. CounterFlow-treated animals showed a statistically significant rise in d-dimer values in the 24-hour cohort only. In the 2-week cohort, CounterFlow-treated animals showed a decrease in body weight at 24 hours after injection but returned to their baseline (normal) body weights at 7 days. Conclusions Findings from this study demonstrate that the tested ingredients of FOAM poloxamer component are safe for intraperitoneal injection and hold potential for further study directed toward prehospital non-compressible intra-abdominal hemorrhage management by non-surgical providers. Although CounterFlow produced abdominal adhesions in 3 of 4 rabbits in the 2-week cohort, these were determined to be "minimal" or "mild" in degree. [ABSTRACT FROM AUTHOR]

Mpox, also known as Monkeypox, is an infectious disease known to spread via direct contact and fomites, which poses a significant contagion risk in surgical settings and may increase the challenges already posed by COVID-19. Within the three years following the outbreak of Mpox, we conducted a review of the impact of Mpox on surgical practice. We searched Pubmed/Medline and Scopus, focusing on original studies and case reports in English or German. Our search terms included "Mpox", "Monkeypox", and "Surgery". Out of 60 clinical or epidemiological studies, as well as expert opinions, brief reports, and pertinent literature reviews, eight were included after full-text assessment. We also incorporated two pertinent literature reviews, including a total of 10 papers, in this analysis. The main topics addressed by the literature are 1. manifestations of Mpox for surgical consideration or urgent management, for which it is important to consider whether a surgical approach is needed to address long-term Mpox-related lesions and 2. infection control in surgical settings, especially considering its impact on elective surgery and the well-being of healthcare workers. Mpox could affect surgical services and access to operating theaters. Unlike COVID-19, Mpox, compared to initial concerns, has not substantially compromised surgical delivery. However, limited reports exist on the surgical impact of Mpox. It is crucial to involve surgeons in Mpox diagnosis, educate surgical practitioners on its mimicry of common surgical conditions, enhance infection control during surgery, and ensure access to corrective surgery as a means of tackling the stigmatization associated with Mpox and sexually transmitted diseases in general.

Hospitals in Europe produce approximately 6 million tons of medical waste annually, about one-third of this originating in operating rooms. Most of it is solid waste, which can be recycled if bodily fluids do not contaminate it. Only 2–3% of hospital waste must be disposed of as infectious waste, and this is much lower than the 50–70% of garbage in the biohazard waste stream. In June 2021, at the main operating room of the Department of General Surgery of the University of Turin, we began a separate collection program for materials consisting of plastic, paper, TNT (material not contaminated by bodily fluids), and biohazardous waste. We calculated the number of boxes and the weight of special waste disposed produced every month in one operating room for 18 months. The monthly number of Sanibox and the monthly weight of biohazardous waste decreased during the observation period. The reduction trend was not constant but showed variations during the 18 months. Direct proportionality between number of low-complexity procedures and production of biohazardous waste was found (p = 0.050). We observed an optimization in the collection and filling of plastic, paper and TNT boxes separated and sent for recycling. One of the barriers to recycling hospital waste, and surgical waste in particular, is the failure to separate infectious waste from clean waste. A careful separate collection of waste in the operating room is the first step in reducing environmental pollution and management costs for the disposal of hospital waste. [ABSTRACT FROM AUTHOR]

Operating rooms (ORs) use energy-intensive equipment such as anesthesia gas machines, patient monitors, and lights. They are major contributors to an institution's carbon footprint; yet ORs are unoccupied 40% of the time. Implementing an initiative to power down electrical devices can reduce energy consumption, equipment failure, and financial outlay. This quality improvement project developed and implemented a power down initiative for anesthesia staff to use in ORs. The initiative included turning off anesthesia gas machines, patient monitors, auxiliary oxygen delivery, and room lights at the end of scheduled cases in ORs that were not used for emergencies. Convenience audits were conducted. Pre- and postimplementation compliance outcomes showed that there was an increase in powering down the anesthesia gas machine, patient monitor, auxiliary oxygen, and room lights. Powering down unnecessary equipment at this facility has the potential to save approximately $50,000 and prevent the emission of over 80 metric tons of CO2 per year. Other facilities can implement a similar quality improvement project aimed at fiscal and ecological conservation. [ABSTRACT FROM AUTHOR]
