RESUMO
BACKGROUND: Out-of-hospital cardiac arrests are a leading global cause of mortality. The American Heart Association (AHA) promotes several important strategies associated with improved cardiac arrest (CA) outcomes, including decreasing pulse check time and maintaining a chest compression fraction (CCF) > 0.80. Video review is a potential tool to improve skills and analyse deficiencies in various situations; however, its use in improving medical resuscitation remains poorly studied in the emergency department (ED). We implemented a quality improvement initiative, which utilised video review of CA resuscitations in an effort to improve compliance with such AHA quality metrics. METHODS: A cardiopulmonary resuscitation video review team of emergency medicine residents were assembled to analyse CA resuscitations in our urban academic ED. Videos were reviewed by two residents, one of whom was a senior resident (Postgraduate Year 3 or 4), and analysed using Spearman's rank correlation coefficient for numerous quality improvement metrics, including pulse check time, CCF, time to intravenous access and time to patient attached to monitor. RESULTS: We collected data on 94 CA resuscitations between July 2017 and June 2020. Average pulse check time was 13.09 (SD ± 5.97) seconds, and 38% of pulse checks were <10 seconds. After the implementation of the video review process, there was a significant decrease in average pulse check time (P = .01) and a significant increase in CCF (P = .01) throughout the study period. CONCLUSIONS: Our study suggests that the video review and feedback process was significantly associated with improvements in AHA quality metrics for resuscitation in CA amongst patients presented to the ED.

BACKGROUND: Previous studies have demonstrated the use of virtual reality (VR) in mass-casualty incident (MCI) simulation; however, it is uncertain if VR simulations can be a substitute for in-person disaster training. Demonstrating that VR MCI scenarios can elicit the same desired stress response achieved in live-action exercises is a first step in showing non-inferiority. The primary objective of this study was to measure changes in sympathetic nervous system (SNS) response via a decrease in heart rate variability (HRV) in subjects participating in a VR MCI scenario. METHODS: An MCI simulation was filmed with a 360º camera and shown to participants on a VR headset while simultaneously recording electrocardiography (EKG) and HRV activity. Baseline HRV was measured during a calm VR scenario immediately prior to exposure to the MCI scenarios, and SNS activation was captured as a decrease in HRV compared to baseline. Cognitive stress was measured using a validated questionnaire. Wilcoxon matched pairs signed rank analysis, Welch's t-test, and multivariate logistic regression were performed with statistical significance established at P <.05. RESULTS: Thirty-five subjects were enrolled: eight attending physicians (two surgeons, six Emergency Medicine [EM] specialists); 13 residents (five Surgery, eight EM); and 14 medical students (six pre-clinical, eight clinical-year students). Sympathetic nervous system activation was observed in all groups during the MCI compared to baseline (P <.0001) and occurred independent of age, sex, years of experience, or prior MCI response experience. Overall, 23/35 subjects (65.7%) reported increased cognitive stress in the MCI (11/14 medical students, 9/13 residents, and 3/8 attendings). Resident and attending physicians had higher odds of discordance between SNS activation and cognitive stress compared to medical students (OR = 8.297; 95% CI, 1.408-64.60; P = .030). CONCLUSIONS: Live-actor VR MCI simulation elicited a strong sympathetic response across all groups. Thus, VR MCI training has the potential to guide acquisition of confidence in disaster response.
RESUMO
BACKGROUND: Medical learners may use YouTube® videos to prepare for procedures. Videos are convenient and readily available, but without any uploading standards, their accuracy and quality for education are uncertain. We assessed the quality of emergency cricothyrotomy videos on YouTube through an expert panel of surgeons with objective quality metrics. METHODS: A YouTube® search for "emergency cricothyrotomy" was performed and results were filtered to remove animations and lectures. The 4 most-viewed videos were sent to a panel of trauma surgeons for evaluation. An educational quality (EQ) score was generated for each video based on its ability to explain the procedure indications, orient the viewer to the patient, provide accurate narration, provide clear views of procedure, identify relevant instrumentation and anatomy, and explain critical maneuvers. Reviewers were also asked if safety concerns were present and encouraged to give feedback in a free-response field. RESULTS: Four surgical attendings completed the survey. The median EQ score was 6 on a 7-point scale (95% CI [6, 6]). All but one of the individual parameters had a median EQ score of 6 (95% CI: indications [3, 7], orientation [5, 7], narration [6, 7], clarity [6, 7], instruments [6, 7], anatomy [6, 6], critical maneuvers [5, 6]). Safety received a lower EQ score (5.5, 95% CI [2, 6]). CONCLUSIONS: The most-viewed cricothyrotomy videos were rated positively by surgical attendings. Still, it is necessary to know if medical learners can distinguish high from low quality videos. If not, this suggests a need for surgical societies to create high-quality videos that can be reliably and efficiently accessed on YouTube®.

BACKGROUND: National databases are increasingly used to research complication rates, risk factors, and the role of comorbidities. Three commonly used databases are the Healthcare Cost and Utilization Program's National Inpatient Sample (NIS), the National Hospital Discharge Survey (NHDS), and the American College of Surgeons National Surgical Quality Improvement Program (NSQIP). Despite many publications, the accuracy of results from these databases remains unclear. METHODS: We compared demographics and complication rates of primary total hip arthroplasty (THA) and primary total knee arthroplasty (TKA) across three national databases from 2006 to 2010. Using International Classification of Diseases, Ninth Revision, Clinical Modification and Current Procedural Terminology codes to identify cases, we calculated postoperative inpatient complication rates in all three databases and 30-day complication rates in the NSQIP. RESULTS: We identified a total of 607,322 TKAs and 279,428 THAs. Overall complication rates varied greatly between the databases. For TKA, the overall complication rates were the highest in the NIS (17.3% [16.6 to 18.0]), followed by the NHDS (14.9% [14.0 to 15.8]), and then the NSQIP 30 days (10.20% [9.73 to 10.70]) and the NSQIP until discharge (7.34% [6.95 to 7.75]). Similarly, for THA, the NIS was the highest (24.09% [23.05 to 25.16]), and then the NHDS (21.5% [19.8 to 23.2]), followed by the NSQIP 30 days (12.00% [11.31 to 12.72]), and the NSQIP until discharge (9.25% [8.64 to 9.90]). Breakdown and comparison of individual adverse events further revealed different complication rates. CONCLUSION: The estimated complication rates from THA and TKA depend on which data source is used because of differences in data collection and sampling methodology. Similar differences may exist in other publications that use such secondary data sources.
