To compare outcomes and costs between major teaching and nonteaching hospitals on a national scale by closely matching on patient procedures and characteristics.Teaching hospitals have been shown to often have better quality than nonteaching hospitals, but cost and value associated with teaching hospitals remains unclear.A study of Medicare patients at 340 teaching hospitals (resident-to-bed ratios ≥ 0.25) and matched patient controls from 2444 nonteaching hospitals (resident-to-bed ratios0.05).We studied 86,751 pairs admitted for general surgery (GS), 214,302 pairs of patients admitted for orthopedic surgery, and 52,025 pairs of patients admitted for vascular surgery.In GS, mortality was 4.62% in teaching hospitals versus 5.57%, (a difference of -0.95%,0.0001), and overall paired cost difference = $915 (P0.0001). For the GS quintile of pairs with highest risk on admission, mortality differences were larger (15.94% versus 18.18%, difference = -2.24%, P0.0001), and paired cost difference = $3773 (P0.0001), yielding $1682 per 1% mortality improvement at 30 days. Patterns for vascular surgery outcomes resembled general surgery; however, orthopedics outcomes did not show significant differences in mortality across teaching and nonteaching environments, though costs were higher at teaching hospitals.Among Medicare patients, as admission risk of mortality increased, the absolute mortality benefit of treatment at teaching hospitals also increased, though accompanied by marginally higher cost. Major teaching hospitals appear to return good value for the extra resources used in general surgery, and to some extent vascular surgery, but this was not apparent in orthopedic surgery.

PURPOSE OF REVIEW Millions of perioperative crises (e.g. anaphylaxis, cardiac arrest) may occur annually. Critical event debriefing can offer benefits to the individual, team, and system, yet only a fraction of perioperative critical events are debriefed in real-time. This publication aims to review evidence-based best practices for proximal critical event debriefing. RECENT FINDINGS Evidence-based key processes to consider for proximal critical event debriefing can be summarized by the WATER mnemonic: Welfare check (assessing team members' emotional and physical wellbeing to continue providing care); Acute/short-term corrections (matters to be addressed before the next case); Team reactions and reflections (summarizing case; listening to team member reactions; plus/delta conversation); Education (lessons learned from the event and debriefing); Resource awareness and longer term needs [follow-up (e.g. safety/quality improvement report), local peer-support and employee assistance resources]. A cognitive aid to accompany this mnemonic is provided with the publication. SUMMARY There is growing literature on how to conduct proximal perioperative critical event debriefing. Evidence-based best practices, as well as a cognitive aid to apply them, may help bridge the gap between theory and clinical practice. In this era of increased attention to burnout and wellness, the consideration of interventions to improve the quality and frequency of critical event debriefing is paramount.

Summary Communication is critical to safe patient care. In this issue of the British Journal of Anaesthesia, Jaulin and colleagues show that use of a Post-Anaesthesia Team Handover (PATH) checklist is associated with fewer hypoxaemia events in the PACU, reduced handover interruptions, and other important metrics related to improved communication. The PATH checklist provides a link within a broader chain of safety checklists and other interventions that comprise a perioperative chain of survival.

Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Debriefing after an actual critical event is an established good practice in medicine, but a gap exists between principle and implementation. The authors’ objective was to understand barriers to debriefing, characterize quantifiable patterns and qualitative themes, and learn potential solutions through a mixed-methods study of actual critical events experienced by anesthesia personnel. Methods At a large academic medical center, anesthesiology residents and a small number of attending anesthesiologists were audited and/or interviewed for the occurrence and patterns of debriefing after critical events during their recent shift, including operating room crises and disruptive behavior. Patterns of the events, including event locations and event types, were quantified. A comparison was done of the proportion of cases debriefed based on whether the event contained a critical communication breakdown. Qualitative analysis, using an abductive approach, was performed on the interviews to add insight to quantitative findings. Results During a 1-yr period, 89 critical events were identified. The overall debriefing rate was 49% (44 of 89). Nearly half of events occurred outside the operating room. Events included crisis events (e.g., cardiac arrest, difficult airway requiring an urgent surgical airway), disruptive behavior, and critical communication breakdowns. Events containing critical communication breakdowns were strongly associated with not being debriefed (64.4% [29 of 45] not debriefed in events with a communication breakdown vs. 36.4% [16 of 44] not debriefed in cases without a communication breakdown; P = 0.008). Interview responses qualitatively demonstrated that lapses in communication were associated with enduring confusion that could inhibit or shape the content of discussions between involved providers. Conclusions Despite the value of proximal debriefing to reducing provider burnout and improving wellness and learning, failure to debrief after critical events can be common among anesthesia trainees and perhaps anesthesia teams. Modifiable interpersonal factors, such as communication breakdowns, were associated with the failure to debrief.

This study aimed to assess the impact of data-driven didactic sessions on metrics including fund of knowledge, resident confidence in clinical topics, and stress in addition to American Board of Anesthesiology In-Training Examination (ITE) percentiles.Observational mixed-methods study.Classroom, video-recorded e-learning.Anesthesiology residents from two academic medical centers.Residents were offered a data-driven didactic session, focused on lifelong learning regarding frequently asked/missed topics based on publicly-available data.Residents were surveyed regarding their confidence on exam topics, organization of study plan, willingness to educate others, and stress levels. Residents at one institution were interviewed post-ITE. The level and trend in ITE percentiles were compared before and after the start of this initiative using segmented regression analysis.Ninety-four residents participated in the survey. A comparison of pre-post responses showed an increased mean level of confidence (4.5 ± 1.6 vs. 6.2 ± 1.4; difference in means 95% CI:1.7[1.5,1.9]), sense of study organization (3.8 ± 1.6 vs. 6.7 ± 1.3;95% CI:2.8[2.5,3.1]), willingness to educate colleagues (4.0 ± 1.7 vs. 5.7 ± 1.9;95% CI:1.7[1.4,2.0]), and reduced stress levels (5.9 ± 1.9 vs. 5.2 ± 1.7;95% CI:-0.7[-1.0,-0.4]) (all p 0.001). Thirty-one residents from one institution participated in the interviews. Interviews exhibited qualitative themes associated with increased fund of knowledge, accessibility of high-yield resources, and domains from the Kirkpatrick Classification of an educational intervention. In an assessment of 292 residents from 2012 to 2020 at one institution, there was a positive change in mean ITE percentile (adjusted intercept shift [95% CI] 11.0[3.6,18.5];p = 0.004) and trajectory over time after the introduction of data-driven didactics.Data-driven didactics was associated with improved resident confidence, stress, and factors related to wellness. It was also associated with a change from a negative to positive trend in ITE percentiles over time. Future assessment of data-driven didactics and impact on resident outcomes are needed.

A saying often attributed to George Bernard Shaw is ‘The single biggest problem in communication is the illusion that it has taken place.’ While it has been debated who originally made this statement, this expression has been used across several industries in different ways.1–4 Communication is an essential aspect of patient safety. One could argue for expanding this proverb to emphasise the importance of recognising that communication at key moments is intrinsically valuable: the biggest problems in communication are the illusion that it has taken place and the assumption that it is not necessary. Over the past 100 years, cognitive aids for crisis events during patient care have been called for, developed, refined and examined.5–12 While much of this literature comes from high-risk industries and medical simulation, there is increasing supporting evidence from healthcare on how these tools can act as cognitive aids in clinical settings. Regarding terminology, we cite a review article on emergency manuals (EMs): ‘EMs are context-relevant sets of cognitive aids, such as crisis checklists, that are intended to provide professionals with key information for managing rare emergency events. Synonyms and related terms include crisis checklists; emergency checklists and cognitive aids, a much broader term, although often also used to describe tools for use during emergency events specifically.’13 Published accounts from healthcare professionals who experienced real-life events have described the power of these tools to prevent errors of omission, commission and lapses in communication.14–18 These events can be both common in large health systems and rare at the level of the individual clinician.10 It is also hard to predict when they will occur. These attributes create a meaningful role to study crisis checklists, EMs and other cognitive aids using medical simulation, particularly in healthcare settings (such as the emergency department (ED)) where …

Critical event debriefing (CED) or ‘hot debriefings’ (HoDs) can be described as a trigger-based, immediate postevent, interprofessional, expertly facilitated conversation where clinicians recount, reflect on, and improve personally and as a team.1 The process and experience of clinicians who cared for the patient is more complex and involves thoughts and emotions that go beyond the ‘case’ or ‘resuscitation’ and the debriefing itself.2 The American Heart Association guidelines for neonatal resuscitation highlight ‘team debriefing’ as a key step in their cognitive aid.3 There is evidence that implementing a ‘Cold Debrief’ programme for teams that care for patients in cardiac arrest improves outcomes4 yet in practice 33% of events are routinely debriefed.5 Critical events in anaesthesia are debriefed infrequently and those associated with communication breakdowns were even less likely to be debriefed6. How do we fuel …

Debriefing after perioperative crises (eg, cardiac arrest, massive hemorrhage) is a well-described practice that can provide benefits to individuals, teams, and health systems. Debriefing has also been embraced by high-stakes industries outside of health care. Yet, in studies of actual clinical practice, there are many critical events that do not get debriefed. This article explores the gap that exists between principle and reality and the factors and strategies to offer opportunities to reflect on actual critical events, when indicated, across the increasing scope of environments where anesthesia care is provided.

Purpose of review The landscape of medical education continues to evolve. Educators and learners must stay informed on current medical literature, in addition to focusing efforts on current educational trends and evidence-based methods. The present review summarizes recent advancements in anesthesiology education, specifically highlighting trends in e-learning and telesimulation, and identifies possible future directions for the field. Recent findings Websites and online platforms continue to be a primary source of educational content; top websites are more likely to utilize standardized editorial processes. Podcasts and videocasts are important tools desired by learners for asynchronous education. Social media has been utilized to enhance the reach and visibility of journal articles, and less often as a primary educational venue; its efficacy in comparison with other e-learning platforms has not been adequately evaluated. Telesimulation can effectively disseminate practical techniques and clinical knowledge sharing, extending the capabilities of simulation beyond previous restrictions in geography, space, and available expertise. Summary E-learning has changed the way anesthesiology learners acquire knowledge, expanding content and curricula available and promoting international collaboration. More work should be done to expand the principles of accessible and collaborative education to psychomotor and cognitive learning via telesimulation.

Objective Traditionally, surgical educators have relied upon participant survey data for the evaluation of educational interventions. However, the ability of such subjective data to completely evaluate an intervention is limited. Our objective was to compare resident and attending surgeons’ self-assessments of coaching sessions from surveys with independent observations from analysis of intraoperative and postoperative coaching transcripts. Design Senior residents were video-recorded operating. Each was then coached by the operative attending in a 1:1 video review session. Teaching points made in the operating room (OR) and in post-OR coaching sessions were coded by independent observers using dialogue analysis then compared using t-tests. Participants were surveyed regarding the degree of teaching dedicated to specific topics and perceived changes in teaching level, resident comfort, educational assessments, and feedback provision between the OR and the post-OR coaching sessions. Setting A single, large, urban, tertiary-care academic institution. Participants Ten PGY4 to 5 general surgery residents and 10 attending surgeons. Results Although the reported experiences of teaching and coaching sessions by residents and faculty were similar (Pearson correlation coefficient = 0.88), these differed significantly from independent observations. Observers found that residents initiated a greater proportion of teaching points and had more educational needs assessments during coaching, compared to the OR. However, neither residents nor attendings reported a change between the 2 environments with regard to needs assessments nor comfort with asking questions or making suggestions. The only metric on which residents, attendings, and observers agreed was the provision of feedback. Conclusions Participants’ perspectives, although considered highly reliable by traditional metrics, rarely aligned with analysis of the associated transcripts from independent observers. Independent observation showed a distinct benefit of coaching in terms of frequency and type of learning points. These findings highlight the importance of seeking different perspectives, data sources, and methodologies when evaluating clinical education interventions. Surgical education can benefit from increased use of dialogue analyses performed by independent observers, which may represent a viewpoint distinct from that obtained by survey methodology.

This chapter describes the concept of crew resource management and development of crisis resource management within the healthcare arena to present a framework for interprofessional team training. Key principles and studies within crew/crisis resource management (CRM) are evaluated and integrated to help the reader develop the tools necessary to design appropriate and effective simulations relevant to all involved team members. Emphasis is placed on how the key principles within CRM can go wrong in a healthcare environment and what can be learned from these failures, with tools and techniques for improved skill building and enhanced awareness of the role of CRM and interprofessional team training on patient care and improved outcomes.

Purpose Preoperative clinics are an increasingly common mechanism for preoperative evaluation. Factors predicting prolonged visit times are poorly understood. Our objective was to identify patient factors that would allow non-medically trained staff to determine appropriate scheduling needs. Methods At the preoperative assessment center of a tertiary care hospital, patient data were prospectively collected on 25 risk factors hypothesized to be related to a prolonged visit length, defined as greater than the unit benchmark of 75 min. The association between these risk factors and prolonged visit length was assessed. Results Data were collected on 1053 patients seen at the preoperative center over a two month period. The median patient age was 58 years (interquartile range [IQR]: 47, 67). A total of 446 patients (42%) had a prolonged visit length. Significant multivariate predictors of a prolonged visit length were: age greater than 80 years ( p = 0.003), taking >6 prescription medications ( p = 0.0002), functional status of p = 0.002), currently having > 3 medical providers ( p = 0.0005), inability to explain details of one's medical history ( p = 0.001), and planned ICU postoperative stay ( p = 0.0004). Conclusions Predictors of prolonged visit length include factors that can be obtained prior to the date of evaluation. Scheduling models integrating such predictors into workflow processes have the potential to improve patient care and allow for more efficient use of resources for the preoperative assessment.

BACKGROUND Failure-to-rescue (FTR), originally developed to study quality of care in surgery, measures an institution's ability to prevent death after a patient becomes complicated. OBJECTIVES Develop an FTR metric modified to analyze acute myocardial infarction (AMI) outcomes. RESEARCH DESIGN Split-sample design: a random 20% of hospitals to develop FTR definitions, a second 20% to validate test characteristics, and an out-of-sample 60% to validate results. SUBJECTS Older Medicare beneficiaries admitted to short-term acute-care hospitals for AMI between 2009 and 2011. MEASURES Thirty-day mortality and FTR rates, and in-hospital complication rates. RESULTS The 60% out-of-sample validation included 234,277 patients across 1142 hospitals that admitted at least 50 patients over 2.5 years. In total, 72.1% of patients were defined as Medically Complicated (complex on admission or subsequently developed a complication or died without a recorded complication) of whom 19.3% died. Spearman r between hospital risk-adjusted 30-day mortality and FTR was 0.89 (P

Purpose This qualitative study sought to characterize the role of debriefing after real critical events among anesthesia residents at the Hospital of the University of Pennsylvania. Method From October 2016 to June 2017 and February to April 2018, the authors conducted 25 semistructured interviews with 24 anesthesia residents after they were involved in 25 unique critical events. Interviews focused on the experience of the event and the interactions that occurred thereafter. A codebook was generated through annotation, then used by 3 researchers in an iterative process to code interview transcripts. An explanatory model was developed using an abductive approach. Results In the aftermath of events, residents underwent a multistage process by which the nature of critical events and the role of residents in them were continuously reconstructed. Debriefing-if it occurred-was 1 stage in this process, which also included stages of internal dialogue, event documentation, and lessons learned. Negotiated in each stage were residents' culpability, reputation, and the appropriateness of their affective response to events. Conclusions Debriefing is one of several stages of interaction that occur after a critical event; all stages play a role in shaping how the event is interpreted and remembered. Because of its dynamic role in constituting the nature of events and residents' role in them, debriefing can be a high-stakes interaction for residents, which can contribute to their reluctance to engage in it. The function and quality of debriefing can be assessed in more insightful fashion by understanding its relation to the other stages of event reconstruction.

BACKGROUND: Teaching hospitals typically pioneer investment in new technology and cultivate workforce characteristics generally associated with better quality, but the value of this extra investment is unclear. OBJECTIVE: Compare outcomes and costs between major teaching and non-teaching hospitals by closely matching on patient characteristics. DESIGN: Medicare patients at 339 major teaching hospitals (resident-to-bed (RTB) ratios ≥ 0.25); matched patient controls from 2439 non-teaching hospitals (RTB ratios

Previous literature on preoperative evaluation focuses on the impact on the day of surgery cancellations and delays; however, the framework of cancellations and delays at the time of the elective outpatient preoperative anesthesia visit has not been categorized. We describe the current model in the preoperative clinic at Brigham and Women's Hospital, examining the pattern of cancellations at the time of this preoperative visit and the framework used for categorizing the issues involved. Looking at this broader framework is important in an era of patient-centered care; we seek to identify targets to modify the preoperative assessment and adequately assess and capture the spectrum of issues involved. Elective cases evaluated in the preoperative clinic were reviewed over 10 months. Characteristics of cancelled and noncancelled cases were compared. In-depth analysis of issues related to cancellation was done; 1-year follow-up was completed. Cancellation patterns included categories encompassing clinical, financial, alignment with patient values and goals, compliance, and social issues. The period of preoperative assessment can therefore be leveraged to review a number of domains that can adversely affect surgical outcomes and improve patient-centered care. Also, our framework allows the institution to benchmark these patterns over time; increases in cancellations at the time of the preoperative anesthesia clinic visit for specific categories can prompt an opportunity to examine and improve preoperative workflow.

Operative catastrophes are low-frequency events that require rapid and coordinated management under stressful conditions. Although these events may be rare at the individual provider level, they can be a common occurrence when viewed in aggregate in large medical centers. As the surgical volume worldwide continues to grow, it is of critical importance in surgical management that we turn our attention to mechanisms of preventing and addressing potentially catastrophic events, such as through the use of structured cognitive aids including crisis checklists and emergency manuals.

This qualitative study examines surgical consultation as a social process and assesses its alignment with assumptions of the shared decision-making (SDM) model.SDM stresses the importance of patient preferences and rigorous discussion of therapeutic risks/benefits based on these preferences. However, empirical studies have highlighted discrepancies between SDM and realities of surgical decision making. Qualitative research can inform understanding of the decision-making process and allow for granular assessment of the nature and causes of these discrepancies.We observed consultations between 3 general surgeons and 45 patients considering undergoing 1 of 2 preference-sensitive elective operations: (1) hernia repair, or (2) cholecystectomy. These patients and surgeons also participated in semi-structured interviews.By the time of the consultation, patients and surgeons were predisposed toward certain decisions by preceding events occurring elsewhere. During the visit, surgeons had differential ability to arbitrate surgical intervention and construct the severity of patients' conditions. These upstream dynamics frequently displaced the centrality of the risk/benefit-based consent discussion.The influence of events preceding consultation suggests that decision-making models should account for broader spatiotemporal spans. Given surgeons' authority to define patients' conditions and control service provision, SDM may be premised on an overestimation of patients' power to alter the course of decision making once in a specialist's office. Considering the subordinate role of the risk/benefit discussion in many surgical decisions, it will be important to study if and how the social process of decision making is altered by SDM-oriented decision aids that foreground this discussion.

Bernoulli (or binomial) regression using a generalized linear model with a log link function, where the exponentiated regression parameters have interpretation as relative risks, is often more appropriate than logistic regression for prospective studies with common outcomes. In particular, many researchers regard relative risks to be more intuitively interpretable than odds ratios. However, for the log link, when the outcome is very prevalent, the likelihood may not have a unique maximum. To circumvent this problem, a 'COPY method' has been proposed, which is equivalent to creating for each subject an additional observation with the same covariates except the response variable has the outcome values interchanged (1's changed to 0's and 0's changed to 1's). The original response is given weight close to 1, while the new observation is given a positive weight close to 0; this approach always leads to convergence of the maximum likelihood algorithm, except for problems with convergence due to multicollinearity among covariates. Even though this method produces a unique maximum, when the outcome is very prevalent, and/or the sample size is relatively small, the COPY method can yield biased estimates. Here, we propose using the jackknife as a bias-reduction approach for the COPY method. The proposed method is motivated by a study of patients undergoing colorectal cancer surgery.

Relative risks (RRs) are often considered the preferred measures of association in prospective studies, especially when the binary outcome of interest is common. In particular, many researchers regard RRs to be more intuitively interpretable than odds ratios. Although RR regression is a special case of generalized linear models, specifically with a log link function for the binomial (or Bernoulli) outcome, the resulting log-binomial regression does not respect the natural parameter constraints. Because log-binomial regression does not ensure that predicted probabilities are mapped to the [0,1] range, maximum likelihood (ML) estimation is often subject to numerical instability that leads to convergence problems. To circumvent these problems, a number of alternative approaches for estimating RR regression parameters have been proposed. One approach that has been widely studied is the use of Poisson regression estimating equations. The estimating equations for Poisson regression yield consistent, albeit inefficient, estimators of the RR regression parameters. We consider the relative efficiency of the Poisson regression estimator and develop an alternative, almost efficient estimator for the RR regression parameters. The proposed method uses near-optimal weights based on a Maclaurin series (Taylor series expanded around zero) approximation to the true Bernoulli or binomial weight function. This yields an almost efficient estimator while avoiding convergence problems. We examine the asymptotic relative efficiency of the proposed estimator for an increase in the number of terms in the series. Using simulations, we demonstrate the potential for convergence problems with standard ML estimation of the log-binomial regression model and illustrate how this is overcome using the proposed estimator. We apply the proposed estimator to a study of predictors of pre-operative use of beta blockers among patients undergoing colorectal surgery after diagnosis of colon cancer.

To test the feasibility of implementing a standardized teamwork training program with full operating room teams in multiple institutions, driven by malpractice insurer support and incentives.Failures in intraoperative teamwork are among the leading causes of preventable patient injury and death in surgical patients. Teamwork training, particularly using simulation, can be an effective intervention but is difficult to scale.A malpractice insurer convened a collaborative with 4 Harvard-affiliated simulation programs to develop a standardized operating room teamwork training curriculum, including principles of communication, assertiveness, and use of the World Health Organization Surgical Safety Checklist. Participant teams were compensated for lost operative time via malpractice premium discounts, continuing education credits, and compensation for lost wages. The course was delivered through a simulation program involving the management of intraoperative emergency scenarios. Participants were surveyed for their perceptions of the program and of its impact on clinical practice.A total of 221 active operating room staff members participated in the program. Each team contained at least 1 attending surgeon, 1 attending anesthesiologist, and 1 operating room nurse (mean size per team: 7 ± 2 participants). No study dates were cancelled because of lack of attendance. The survey response rate was 99% (218/221). Overall, the vast majority of participants found the scenarios realistic [94% (95% confidence interval: 90.9%, 97.2%)], appropriately challenging [95.4% (92.6%, 98.2%)], relevant to their practice [96.3% (93.8%, 98.8%)], and found the training would help them provide safer patient care [92.6% (89.1%, 96.1%)]. Surgeons reported their greatest personal deficit as communication skills. Operating room nurses and anesthesiologists reported a greater need than surgeons to work on personal assertiveness.A standardized multicenter team training program involving full operative teams is feasible with high-fidelity simulation and modest compensation for lost time. The vast majority of the multidisciplinary participants believed the course to have had a meaningful impact on their approach to clinical practice.

Background: More than a quarter of medical costs for Medicare beneficiaries are incurred in the last year of life; surgical intensity during this time is significant. This study was performed to determine types of operations patients undergo in their terminal year, and compare characteristics of decedents with those of survivors. Methods: Population of 747 consecutive all-payer patients seen at the preoperative assessment center of a tertiary care hospital. Patient characteristics were obtained from the electronic medical record. Surgical indication (palliative, curative, diagnostic, elective) was assessed based on procedure performed and underlying diagnosis. Vital status was determined using the electronic medical record with confirmation via social security national death master file. Descriptive statistics were performed to compare patient characteristics and procedures performed on those who died within 1 yr of procedure with those of survivors. Results: Thirty-seven patients (5%) were confirmed dead at 1 yr. Ten (27%) of these had palliative procedures, 11 (30%) diagnostic, 14 (38%) curative, and 2 (5%) elective. Decedents were more likely to have undergone a palliative (27 vs. 3%) or diagnostic (30 vs. 14%) procedure and less likely to have undergone an elective procedure (5 vs. 42%) than survivors (P < 0.0001). Nearly half of decedents did not have an advanced directive by the date of surgical intervention. Conclusions: Nearly 1 in 20 patients seen at the preoperative assessment clinic of a tertiary care hospital died within 1 yr of their procedure. Patient characteristics and procedure indication for decedents differed from those of survivors. Similar analyses based on institution and region may provide methodologies to compare variation in surgical intensity and assist preoperative care providers in evaluating appropriateness of resource allocation.

Communication failure is a common contributor to adverse events. We sought to characterize communication failures during complex operations.We video recorded and transcribed six complex operations, representing 22 h of patient care. For each communication event, we determined the participants and the content discussed. Failures were classified into four types: audience (key individuals missing), purpose (issue nonresolution), content (insufficient/inaccurate information), and/or occasion (futile timing). We added a systems category to reflect communication occurring at the organizational level. The impact of each identified failure was described.We observed communication failures in every case (mean 29, median 28, range 13-48), at a rate of one every 8 min. Cross-disciplinary exchanges resulted in failure nearly twice as often as intradisciplinary ones. Discussions about or mandated by hospital policy (20%), personnel (18%), or other patient care (17%) were most error prone. Audience and purpose each accounted for40% of failures. A substantial proportion (26%) reflected flawed systems for communication, particularly those for disseminating policy (29% of system failures), coordinating personnel (27%), and conveying the procedure planned (27%) or the equipment needed (24%). In 81% of failures, inefficiency (extraneous discussion and/or work) resulted. Resource waste (19%) and work-arounds (13%) also were frequently seen.During complex operations, communication failures occur frequently and lead to inefficiency. Prevention may be achieved by improving synchronous, cross-disciplinary communication. The rate of failure during discussions about/mandated by policy highlights the need for carefully designed standardized interventions. System-level support for asynchronous perioperative communication may streamline operating room coordination and preparation efforts.

To develop and evaluate an intervention to reduce breakdowns in communication during inpatient surgical care.Communication breakdowns are the second most common cause of avoidable surgical adverse events after technical errors.In a pre- and postintervention study, a random selection of patients on the surgical services of 4 teaching hospitals were observed according to 3 measures: (1) resident-attending communication of critical patient events (eg, transfer into the intensive care unit, unplanned intubation, cardiac arrest); (2) resident-attending notification regarding routine weekend patient status; and (3) frequency of weekend patient visits by an attending. All departments then developed and adopted a set of policy and education initiatives designed to increase prompt and consistent resident-attending communication (especially in critical events) and to improve regular attending visits with surgical patients. Specific reinforcement of the policies included a pocket information card for residents, as well as periodic reminders. Repeat audits of the surgical services were then conducted.We reviewed information for 211 critical events and 1360 patients for the nature of resident and attending communication practices. After the intervention, the proportion of critical events not conveyed to an attending decreased from 33% (26/80) to 2% (1/47), and gaps in the frequency of attending notification of patient status on weekends were virtually eliminated (P0.0001); the proportion of weekend patients not visited by an attending for greater than 24 hours decreased by half (from 61% to 33%; P = 0.0002). Contact resulted in attending-led changes in patient management in one-third of cases.An intervention to improve surgical communication practices at 4 teaching hospitals led to significant reductions in potentially harmful communication breakdowns during inpatient care; significant alterations in patient management were noted in one-third of cases in which there was an adherence to recommended communication practices.

Little information exists on the incidence of complications after acellular human dermis implantation in two-stage tissue expander breast reconstruction. The purpose of this study was to evaluate the incidence of postoperative adverse events and identify significant predictors of complications in acellular human dermis tissue expander breast reconstruction.This study accrued all patients from January of 2004 through April of 2008 undergoing two-stage immediate tissue expander breast reconstruction using acellular human dermis. A total of 153 expanders were placed. Complications were assessed. Univariate and multivariate logistic regression modeling was performed. Comparison of complication rates using the traditional (non-acellular human dermis) technique from concurrent (2004 to 2008) and consecutive time periods (2001 to 2003) for 2910 and 1170 expanders, respectively, is provided.A total of 153 expanders were implanted in 96 women: 39 unilateral and 57 bilateral. Eleven (7.2 percent) were removed due to infection (n = 5, 3.3 percent), exposure (n = 4, 2.6 percent), or patient preference (n = 2, 1.3 percent). Other complications included cellulitis (3.9 percent), seroma (7.2 percent), hematoma (2.0 percent), mastectomy flap necrosis (4.6 percent), and leak/failed expansion (0.0 percent); 92.8 percent were successfully expanded and exchanged for a permanent implant. Eleven seromas (7.2 percent) were identified; nine underwent aspiration. None of these resulted in infection or reconstructive failure. Univariate analysis revealed age, body mass index, axillary dissection, and postoperative chemotherapy to be associated with reconstructive failure (p0.05). Multivariate analysis revealed that age, body mass index, and axillary dissection are independent risk factors for developing complications (p0.05).Acellular human dermis is a useful adjunct for intraoperative pocket development in immediate tissue expander reconstruction but can result in an increased risk of complications, in particular, seroma and reconstructive failure.

Background: Communication breakdowns between surgical residents and attending physicians in the pre- and postoperative setting are common contributors to patient injury. These communication transactions might offer an opportunity for safety improvement, but it remains unknown how often resident-attending communication fails, what the current level of attending involvement is, and how often attending input changes the plan for patient care. We conducted a prospective study at 4 Harvard teaching hospitals to address these issues. Methods: Three prospective data collection strategies were employed: (1) we randomly selected surgical services and queried residents for the occurrence of predefined critical patient events and the characteristics of attending communications that ensued, (2) on weekends, randomly selected patients were interviewed and their charts reviewed to identify the frequency of attending visitation and how such visits affected processes of care, and (3) on weekends, senior residents on randomly selected surgical services were queried regarding the occurrence of attending-resident discussion of patients in their care. Results: Of 80 critical patient events identified, 26 (33%) were not communicated to attending surgeons. Residents reported that, when contacted, all attending physicians were receptive to communication, whether they were the primary surgeon or providing cross-coverage. Although residents felt that attending contact was unnecessary for safe patient care in 61 (76%) of these events, discussions with attending physicians changed management in 33% (18/54) of cases in which they occurred. Attending surgeons were found to visit their patients on randomly selected weekend days 42% (n = 37) of the time, while 21% (n = 19) had not visited for 2 or greater days. When attending physicians visited patients, however, resident management was modified 46% (n = 36) of the time. Though residents frequently discussed patient management with attending physicians on randomly selected weekends, they failed to do so 16% (n = 58) of the time, which appeared to be related to service-specific variation (χ 2 = 269, P < 0.0001). Conclusions: In the context of both critical patient events and routine patient care, residents often fail to obtain attending surgeons' input for management decisions. These failures seem to derive more from residents' perception of necessity than from attending physicians' receptiveness or interest in being contacted. Once involved, attending physicians frequently modify resident's management decisions. It seems, therefore, that there is significant potential for communication failure and information loss among our 4 institutions.

Objective: To evaluate whether adherence to evidence-based best practices in colorectal surgery predicts improved postoperative outcomes. Summary and Background Data: Over a quarter of a million colon and rectal resections are performed annually in the United States. The average postoperative complication rate for these procedures approaches 30%. Methods: A panel of colorectal and general surgeons from 3 hospitals 11 academic medical center and 2 community hospitals) was assembled to ascertain a set of 37 evidence-based practices that they felt were the most pertinent to the evaluation and management of a patient undergoing a colorectal resection. Fifteen of these practices were classified as "key processes" for the prevention of complications. We then retrospectively reviewed medical records for 370 consecutive patients undergoing colorectal resection at these institutions. We evaluated the association of best-practice adherence to complications in the subset of patients with outcome data available through the American College of Surgeons National Surgical Quality Improvement Program. Results: Nonadherence rates exceeded 40% for 11 practices (including 2 key processes: avoidance of unnecessary blood transfusions and timely removal of central venous catheters). Among 198 patients with American College of Surgeons National Surgical Quality Improvement Program outcomes data, 38 (19%) experienced complications, of which 31 (82%) involved postoperative infection. Nonadherence to key-processes significantly predicted the occurrence of a complication (P = 0.002). Each additional process missed increased the odds of a postoperative complication by 60% (odds ratio: 1.6; 95% confidence interval: 1.2―2.2). Conclusions: Failures of adherence with best practices in colorectal surgery is associated with an increased occurrence of complications. This study merits further research to confirm that improvement in compliance with perioperative best practices will reduce complication rates significantly.

The importance of leadership is recognized in surgery, but the specific impact of leadership style on team behavior is not well understood. In other industries, leadership is a well-characterized construct. One dominant theory proposes that transactional (task-focused) leaders achieve minimum standards and transformational (team-oriented) leaders inspire performance beyond expectations.We videorecorded 5 surgeons performing complex operations. Each surgeon was scored on the Multifactor Leadership Questionnaire, a validated method for scoring transformational and transactional leadership style, by an organizational psychologist and a surgeon researcher. Independent coders assessed surgeons' leadership behaviors according to the Surgical Leadership Inventory and team behaviors (information sharing, cooperative, and voice behaviors). All coders were blinded. Leadership style (Multifactor Leadership Questionnaire) was correlated with surgeon behavior (Surgical Leadership Inventory) and team behavior using Poisson regression, controlling for time and the total number of behaviors, respectively.All surgeons scored similarly on transactional leadership (range 2.38 to 2.69), but varied more widely on transformational leadership (range 1.98 to 3.60). Each 1-point increase in transformational score corresponded to 3 times more information-sharing behaviors (p0.0001) and 5.4 times more voice behaviors (p = 0.0005) among the team. With each 1-point increase in transformational score, leaders displayed 10 times more supportive behaviors (p0.0001) and displayed poor behaviors 12.5 times less frequently (p0.0001). Excerpts of representative dialogue are included for illustration.We provide a framework for evaluating surgeons' leadership and its impact on team performance in the operating room. As in other fields, our data suggest that transformational leadership is associated with improved team behavior. Surgeon leadership development, therefore, has the potential to improve the efficiency and safety of operative care.

Background The aim of this study was to evaluate labor and delivery outcomes in parturients with inadvertent dural puncture managed by either insertion of an intrathecal catheter or a resited epidural catheter. Methods This was a retrospective cohort review of 235 parturients who had an inadvertent dural puncture during epidural placement over a six-year period. The primary outcome was the proportion of women with a delayed second stage of labor. Secondary outcomes were the proportion of cesarean deliveries, the proportion of cases resulting in post-dural puncture headache, and the incidence of failed labor analgesia. Results Baseline characteristics such as age, body mass index and parity were similar between the two groups. Among the 236 cases of inadvertent dural puncture, 173 women (73%) had an intrathecal catheter placed while 63 women (27%) had the epidural catheter resited. Comparing intrathecal with epidural catheters, there was no observed difference in the proportion of cases of prolonged second stage of labor (13% vs. 16%, P =0.57) and the overall rate of cesarean deliveries (17% vs. 16%, P =0.78). However, we observed a lower rate of post-dural puncture headache in women who had cesarean delivery compared to vaginal delivery (53% vs. 74%, P =0.007). A greater proportion of failed labor analgesia was observed in the intrathecal catheter group (14% vs. 2%, P =0.005). Conclusion The choice of neuraxial technique following inadvertent dural puncture does not appear to alter the course of labor and delivery. Cesarean delivery decreased the incidence of post-dural puncture headache by 35%. Intrathecal catheters were associated with a higher rate of failed analgesia.

Operating-room crises (e.g., cardiac arrest and massive hemorrhage) are common events in large hospitals but can be rare for individual clinicians. Successful management is difficult and complex. We sought to evaluate a tool to improve adherence to evidence-based best practices during such events.Operating-room teams from three institutions (one academic medical center and two community hospitals) participated in a series of surgical-crisis scenarios in a simulated operating room. Each team was randomly assigned to manage half the scenarios with a set of crisis checklists and the remaining scenarios from memory alone. The primary outcome measure was failure to adhere to critical processes of care. Participants were also surveyed regarding their perceptions of the usefulness and clinical relevance of the checklists.A total of 17 operating-room teams participated in 106 simulated surgical-crisis scenarios. Failure to adhere to lifesaving processes of care was less common during simulations when checklists were available (6% of steps missed when checklists were available vs. 23% when they were unavailable, P0.001). The results were similar in a multivariate model that accounted for clustering within teams, with adjustment for institution, scenario, and learning and fatigue effects (adjusted relative risk, 0.28; 95% confidence interval, 0.18 to 0.42; P0.001). Every team performed better when the crisis checklists were available than when they were not. A total of 97% of the participants reported that if one of these crises occurred while they were undergoing an operation, they would want the checklist used.In a high-fidelity simulation study, checklist use was associated with significant improvement in the management of operating-room crises. These findings suggest that checklists for use during operating-room crises have the potential to improve surgical care. (Funded by the Agency for Healthcare Research and Quality.).

Surgical expertise demands technical and nontechnical skills. Traditionally, surgical trainees acquired these skills in the operating room; however, operative time for residents has decreased with duty hour restrictions. As in other professions, video analysis may help maximize the learning experience.To develop and evaluate a postoperative video-based coaching intervention for residents.In this mixed methods analysis, 10 senior (postgraduate year 4 and 5) residents were videorecorded operating with an attending surgeon at an academic tertiary care hospital. Each video formed the basis of a 1-hour one-on-one coaching session conducted by the operative attending; although a coaching framework was provided, participants determined the specific content collaboratively. Teaching points were identified in the operating room and the video-based coaching sessions; iterative inductive coding, followed by thematic analysis, was performed.Teaching points made in the operating room were compared with those in the video-based coaching sessions with respect to initiator, content, and teaching technique, adjusting for time.Among 10 cases, surgeons made more teaching points per unit time (63.0 vs 102.7 per hour) while coaching. Teaching in the video-based coaching sessions was more resident centered; attendings were more inquisitive about residents' learning needs (3.30 vs 0.28, P = .04), and residents took more initiative to direct their education (27% [198 of 729 teaching points] vs 17% [331 of 1977 teaching points], P .001). Surgeons also more frequently validated residents' experiences (8.40 vs 1.81, P .01), and they tended to ask more questions to promote critical thinking (9.30 vs 3.32, P = .07) and set more learning goals (2.90 vs 0.28, P = .11). More complex topics, including intraoperative decision making (mean, 9.70 vs 2.77 instances per hour, P = .03) and failure to progress (mean, 1.20 vs 0.13 instances per hour, P = .04) were addressed, and they were more thoroughly developed and explored. Excerpts of dialogue are presented to illustrate these findings.Video-based coaching is a novel and feasible modality for supplementing intraoperative learning. Objective evaluation demonstrates that video-based coaching may be particularly useful for teaching higher-level concepts, such as decision making, and for individualizing instruction and feedback to each resident.

More than a quarter of medical costs for Medicare beneficiaries are incurred in the last year of life; surgical intensity during this time is significant. This study was performed to determine types of operations patients undergo in their terminal year, and compare characteristics of decedents with those of survivors.Population of 747 consecutive all-payer patients seen at the preoperative assessment center of a tertiary care hospital. Patient characteristics were obtained from the electronic medical record. Surgical indication (palliative, curative, diagnostic, elective) was assessed based on procedure performed and underlying diagnosis. Vital status was determined using the electronic medical record with confirmation via social security national death master file. Descriptive statistics were performed to compare patient characteristics and procedures performed on those who died within 1 yr of procedure with those of survivors.Thirty-seven patients (5%) were confirmed dead at 1 yr. Ten (27%) of these had palliative procedures, 11 (30%) diagnostic, 14 (38%) curative, and 2 (5%) elective. Decedents were more likely to have undergone a palliative (27 vs. 3%) or diagnostic (30 vs. 14%) procedure and less likely to have undergone an elective procedure (5 vs. 42%) than survivors (P0.0001). Nearly half of decedents did not have an advanced directive by the date of surgical intervention.Nearly 1 in 20 patients seen at the preoperative assessment clinic of a tertiary care hospital died within 1 yr of their procedure. Patient characteristics and procedure indication for decedents differed from those of survivors. Similar analyses based on institution and region may provide methodologies to compare variation in surgical intensity and assist preoperative care providers in evaluating appropriateness of resource allocation.

To understand the etiology and resolution of unanticipated events in the operating room (OR).The majority of surgical adverse events occur intraoperatively. The OR represents a complex, high-risk system. The influence of different human, team, and organizational/environmental factors on safety and performance is unknown.We video-recorded and transcribed 10 high-acuity operations, representing 43.7 hours of patient care. Deviations, defined as delays and/or episodes of decreased patient safety, were identified by majority consensus of a multidisciplinary team. Factors that contributed to each event and/or mitigated its impact were determined and attributed to the patient, providers, or environment/organization.Thirty-three deviations (10 delays, 17 safety compromises, 6 both) occurred--with a mean of 1 every 79.4 minutes. These deviations were multifactorial (mean 3.1 factors). Problems with communication and organizational structure appeared repeatedly at the root of both types of deviations. Delays tended to be resolved with vigilance, communication, coordination, and cooperation, while mediation of safety compromises was most frequently accomplished with vigilance, leadership, communication, and/or coordination. The organization/environment was not found to play a direct role in compensation.Unanticipated events are common in the OR. Deviations result from poor organizational/environmental design and suboptimal team dynamics, with caregivers compensating to avoid patient harm. Although recognized in other high-risk domains, such human resilience has not yet been described in surgery and has major implications for the design of safety interventions.

Background The surgical learning curve persists for years after training, yet existing continuing medical education activities targeting this are limited. We describe a pilot study of a scalable video-based intervention, providing individualized feedback on intraoperative performance. Study Design Four complex operations performed by surgeons of varying experience—a chief resident accompanied by the operating senior surgeon, a surgeon with less than 10 years in practice, another with 20 to 30 years in practice, and a surgeon with more than 30 years of experience—were video recorded. Video playback formed the basis of 1-hour coaching sessions with a peer-judged surgical expert. These sessions were audio recorded, transcribed, and thematically coded. Results The sessions focused on operative technique—both technical aspects and decision-making. With increasing seniority, more discussion was devoted to the optimization of teaching and facilitation of the resident's technical performance. Coaching sessions with senior surgeons were peer-to-peer interactions, with each discussing his preferred approach. The coach alternated between directing the session (asking probing questions) and responding to specific questions brought by the surgeons, depending on learning style. At all experience levels, video review proved valuable in identifying episodes of failure to progress and troubleshooting alternative approaches. All agreed this tool is a powerful one. Inclusion of trainees seems most appropriate when coaching senior surgeons; it may restrict the dialogue of more junior attendings. Conclusions Video-based coaching is an educational modality that targets intraoperative judgment, technique, and teaching. Surgeons of all levels found it highly instructive. This may provide a practical, much needed approach for continuous professional development.

Background “War stories” are commonplace in surgical education, yet little is known about their purpose, construct, or use in the education of trainees. Methods Ten complex operations were videotaped and audiotaped. Narrative stories were analyzed using grounded theory to identify emergent themes in both the types of stories being told and the teaching objectives they illustrated. Results Twenty-four stories were identified in 9 of the 10 cases (mean, 2.4/case). They were brief (mean, 58 seconds), illustrative of multiple teaching points (mean, 1.5/story), and appeared throughout the operations. Anchored in personal experience, these stories taught both clinical (eg, operative technique, decision making, error identification) and programmatic (eg, resource management, professionalism) topics. Conclusions Narrative stories are used frequently and intuitively by physicians to emphasize a variety of intraoperative teaching points. They socialize trainees in the culture of surgery and may represent an underrecognized approach to teaching the core competencies. More understanding is needed to maximize their potential.
