The Ross procedure has several advantages, but the need for reintervention is inevitable. The aim of this study was to examine the complexity and outcomes of reoperation after the Ross procedure.Retrospective chart review was performed of patients with a prior Ross procedure who underwent reoperation at our institution from September 1991 to January 2021. Demographic, echocardiographic, surgical, and perioperative data were collected. Descriptive statistical and regression analyses were performed.A total of 105 patients underwent a reoperation at Mayo Clinic after the initial Ross procedure performed at our institution (n = 16; 16.2%) or elsewhere (n = 83; 83.8%). Mean age at the Ross procedure was 27 ± 17 years, and mean age at reoperation at our institution was 37 ± 19 years. Indications for surgical procedure varied, but 64% had autograft regurgitation as 1 of their indications for reoperation. Autograft interventions were performed in 78 patients (74.2%). Pulmonary valve or conduit replacement was performed in 56 patients (53.3%). Double root replacement was performed in 11 patients (10.5%). Aortic reconstruction was performed in 37 patients (38.4%). There were 5 early deaths (5%). During a median follow-up of 6.25 years (3 months-24 years), late deaths occurred in 14 patients (13.1%). Patients with ejection fraction30% on preoperative echocardiography had shorter duration between the Ross procedure and subsequent reoperation (P = .03).Reoperations after the Ross procedure are performed for a wide range of indications, with most due to autograft dysfunction. The number of early deaths is not low. Reoperation after the Ross procedure should be advised before left ventricular systolic dysfunction.

BackgroundCurrent military recommendations include the use of tourniquets (TQ) in appropriate pediatric trauma patients. Although the utility of TQs has been well documented in adult patients, the efficacy of TQ application in pediatric patients is less clear. The current study attempted to identify physical constraints for TQ use in two simulated pediatric limb models.MethodsFive different TQ (Combat Application Tourniquet (CAT) Generation 6 and Generation 7, SOFTT (SOF Tactical Tourniquet), SOFTT-W (SOF Tactical Tourniquet – Wide), SWAT-T (Stretch Wrap and Tuck – Tourniquet) and a trauma dressing were evaluated in two simulated pediatric limb models. Model one employed four cardiopulmonary resuscitation (CPR) manikins simulating infant (Simulaids SaniBaby), 1 year (Gaumard HAL S3004), and 5 years (Laerdal Resusci Junior, Gaumard HAL S3005). Model two utilized polyvinyl chloride (PVC) piping with circumferences ranging from 4.25” to 16.5”. Specific end-points included tightness of the TQ and ability to secure the windlass (where applicable).ResultsIn both models, the ability to successfully apply and secure the TQ depended upon the simulated limb circumference. In the 1-year-old CPR manikin, all windlass TQs failed to tighten on the upper extremity, while all TQs successfully tightened at the high leg and mid-thigh. With the exception of the CAT7 and the SOFTT-W at the mid-thigh, no windlass TQ was successfully tightened at any extremity location on the infant. The SWAT-T was successfully tightened over all sites of all CPR manikins except the infant. No windlass TQ was able to tighten on PVC pipe 5.75” circumference or smaller (age < 24 months upper extremity). All windlass TQs were tightened and secured on the 13.25” and 15.5” circumference PVC pipes (age 7–12 years lower extremity, age >13 years upper extremity). The SWAT-T was tightened on all PVC pipes.DiscussionThe current study suggests that commercial windlass TQs can be applied to upper and lower extremities of children aged 5 years and older at the 50%th percentile for limb circumference. In younger children, windlass TQ efficacy is variable. Further study is required to better understand the limitations of TQs in the youngest children, and to determine actual hemorrhage control efficacy.

Introduction This study aimed to describe interruptions experienced by emergency nurses and establish convergence validity of 1 objective workload measure by linking interruption characteristics to objective and subjective measures of workload. Methods Interruptions were captured in real time across 8- or 12-hour shifts using a previously validated Workflow Interruptions Tool (WIT). Data collected on each interruption included type, priority, and location where the interruption occurred. At mid- and end-shift, the Surgery Task Load Index (SURG-TLX) and the Rapid Cognitive Assessment Tool (RCAT) were administered to participating nurses to measure workload subjectively and objectively. Results Thirty-eight emergency nurse shifts were observed. A total of 3,229 interruptions were recorded across 372.5 clinical hours and 38 shifts (means [M] = 85.0 interruptions per shift, standard deviation [SD] = 34.9; M=8.7 interruptions per hour, SD=3.36). The median duration per interruption was 13.0 seconds. A moderate positive association was identified between the number of interruptions experienced during a shift and the increased overall SURG-TLX workload reported at end-shift, r(36) = 0.323, P = 0.048. Also, a moderate positive association was identified between increased reaction times during the RCAT task and increased mental demand experienced at end of shift, r (36) = 0.460, P Discussion This study observed interruptions throughout the entirety of a nursing shift and found that the majority of interruptions caused by the environment were low priority. Targeting interventions to reduce low-priority and environmental interruptions may aid in alleviating the impact of interruptions on clinical staff and patient care. Furthermore, results demonstrate that the frequency of interruptions was perceived to increase the nursing staff workload overall.Unlabelled BoxContribution to Emergency Nursing Practice •Emergency nurses perceived their own workload accurately. •Interruptions occur every 6 to 7 minutes for emergency nurses. •Frequency of interruptions increased the nursing staff workload overall.

Interruptions in the emergency department (ED) have been studied across multiple clinical roles, with little investigation into how residents experience interruptions. Therefore this pilot study aimed to characterize interruptions experienced by emergency medicine (EM) residents at various post-graduate year (PGY) levels. Observers shadowed ED residents across entire shifts and logged interruptions that affected clinicians into the Workflow Interruption Tool (WIT). Interruption characteristics captured included duration, nature, location, and task priority. Chi-square analysis identified a significant association between interruption type and the interruption priority, p < 0.001. Residents at varying PGY-levels experienced significantly different amounts of interruptions, p=0.013. Observing resident interruptions across the entirety of their shifts identified that as EM residents gain more experience, they are interrupted more often while working in the ED.

Highlights • Contact tracing is an essential step in infectious disease control and prevention. • Using Electronic medical record (EMR) is challenging and misses a number of potential exposures. • Real time location system (RTLS) doubled the potential exposures list for pertussis disease beyond the conventional method of EMR-based contact identification • RTLS is more efficient and timely in the process of contact tracing. • Further studies with larger sample size are needed to confirm the findings., Background Contact tracing is the systematic method of identifying individuals potentially exposed to infectious diseases. Electronic medical record (EMR) use for contact tracing is time-consuming and may miss exposed individuals. Real-time location systems (RTLSs) may improve contact identification. Therefore, the relative effectiveness of these 2 contact tracing methodologies were evaluated. Methods During a pertussis outbreak in the United States, a retrospective case study was conducted between June 14 and August 31, 2016, to identify the contacts of confirmed pertussis cases, using EMR and RTLS data in the emergency department of a tertiary care medical center. Descriptive statistics and a paired t test (α = 0.05) were performed to compare contacts identified by EMR versus RTLS, as was correlation between pertussis patient length of stay and the number of potential contacts. Results Nine cases of pertussis presented to the emergency department during the identified time period. RTLS doubled the potential exposure list (P

Interruptions in the Emergency Department (ED) are moderately studied in regard to their impact on physicians’ workload. This study captured interruptions characteristics and measures of workload. Twenty-eight ED physicians were followed during their shifts; interruptions they faced were captured using a validated tablet PC-based tool. At the mid and end of their shift, providers completed a NASA-Task Load Index (TLX) questionnaire and a reaction time task. Descriptive statistics and ANOVA were used to identify relationships between physicians’ interruptions and workload. A total of 2355 interruptions were identified ( M =84.1, SD =14.5). The NASA-TLX results showed increase in physicians’ responses for all subscales from mid to end-shifts. Reaction time was higher at end-shift with mean difference of 33.75ms, 95% CI [20.35, 47.13], p < 0.001. At end-shift, there was a statistically significant positive correlation between reaction time and all NASA-TLX subscales. Interruption duration rather than frequency correlated positively with NASA-TLX scores. High/critical interruptions were the least frequent but had longer duration and greater impact on workload. This study provided a unique examination of interruptions over an entire provider shift and identified interruptions as potential causes of increased workload for ED physicians.

Clinicians have anecdotally indicated that interruptions increase following trauma activations in the emergency department (ED), yet it is unknown whether interruptions change following the end of a trauma case. This study aimed to examine the interruption characteristics of clinicians that participate in trauma activations before and after activations using the SEIPS model. Observers shadowed ED clinicians across entire shifts and logged interruptions that affected clinicians in a tablet PC-based tool. Interruption characteristics captured included duration, nature, location, and task priority. Trauma activations lasting more than five minutes were also recorded. Only interruptions occurring within one-hour of trauma activations were included in the analysis. Chi-square analyses identified significant associations between SEIPS-categorized interruptions and the interruption priority, p < 0.01, and between the SEIPS-categorized interruptions and the interruption location, p = 0.01, pre- and post-trauma activations. Identifying these associations revealed key opportunities to reduce unnecessary interruptions in the ED.

Background It is unclear how workflow interruptions impact emergency physicians at the point of care. Objectives Our study aimed to evaluate interruption characteristics experienced by academic emergency physicians. Methods This prospective, observational study collected interruptions during attending physician shifts. An interruption is defined as any break in performance of a human activity that briefly requires attention. One observer captured interruptions using a validated tablet PC-based tool that time stamped and categorized the data. Data collected included: 1) type, 2) priority of interruption to original task, and 3) physical location of the interruption. A Kruskal-Wallis H test compared interruption priority and duration. A chi-squared analysis examined the priority of interruptions in and outside of the patient rooms. Results A total of 2355 interruptions were identified across 210 clinical hours and 28 shifts (means = 84.1 interruptions per shift, standard deviation = 14.5; means = 11.21 interruptions per hour, standard deviation = 4.45). Physicians experienced face-to-face physician interruptions most frequently (26.0%), followed by face-to-face nurse communication (21.7%), and environment (20.8%). There was a statistically significant difference in interruption duration based on the interruption priority, χ2(2) = 643.98, p Conclusions Our study examined interruptions over entire provider shifts and identified patient rooms as high risk for low-priority interruptions. Targeting provider-centered interventions to patient rooms may aid in mitigating the impacts of interruptions on patient safety and enhancing clinical care.
