Impact of video recordings review with structured debriefings on trauma team performance: a prospective observational cohort study.

PURPOSE: To determine the impact of structured debriefings (SD) with audio/video review of trauma patients' resuscitation events on trauma team (TT) technical and non-technical skills. METHODS: Single-center prospective observational cohort study. The study included all emergency department patients aged 18 years or older who received resuscitation from the TT. Virtual meeting was held with the TT using SD to review one trauma patient resuscitation video. Technical skills improvement was based on adherence to the ATLS protocol and non-technical skills based on T-NOTECHS scale. RESULTS: There was statistically significant improvement in adherence to the ATLS protocol: 73% [55-82%] vs 91% [82-100%] (p < 0.001); and improvement in T-NOTECHS scale: 12 [10-14] vs 16 [14-19] points (p < 0.001). CONCLUSION: In this study, we found that structured debriefings with review of patients' resuscitation video recordings can have a significant positive impact on trauma team performance in the emergency department in both technical and non-technical skills.

AI-Enabled Public Surveillance Cameras for Rapid Emergency Medical Service Activation in Out-of-Hospital Cardiac Arrests.

This study aims to evaluate the potential usefulness of a novel artificial intelligence (AI)-based video processing algorithm for rapidly activating ambulance services (EMS) in unwitnessed out-of-hospital cardiac arrest (OHCA) cases in public places. We hypothesized that AI should activate EMS using public surveillance cameras after detecting a person fallen due to OHCA. We created an AI model based on our experiment performed at the Lithuanian University of Health Sciences, Kaunas, Lithuania, in Spring 2023. Our research highlights the potential benefits of AI-based surveillance cameras for rapidly detecting and activating EMS during cardiac arrests.

Short- and long-term survival after out-of-hospital cardiac arrest in Kaunas (Lithuania) from 2016 to 2018.

BACKGROUND: No studies analysing out-of-hospital cardiac arrest (OHCA) epidemiology and outcomes in Lithuania were published in the last decade. METHODS: We conducted a retrospective analysis of prospectively collected data. The incidence of OHCA and the demographics and outcomes of patients who were treated for OHCA between 1 and 2016 and 31 December 2018 at Kaunas Emergency Medical Service (EMS) were collected and are reported in accordance with the Utstein recommendations. Multivariable logistic regression analysis was used to identify predictors of survival to hospital discharge. RESULTS: In total, 838 OHCA cases of EMS-treated cardiac arrest (CA) were reported (95.8 per 100.000 inhabitants). The median age was 71 (IQR 58-81) years of age, and 66.7% of patients were males. A total of 73.8% of OHCA cases occurred at home, 59.3% were witnessed by a bystander, and 54.5% received bystander cardiopulmonary resuscitation. The median EMS response time was 10 min. Cardiac aetiology was the leading cause of CA (78.8%). The initial rhythm was shockable in 27.6% of all cases. Return of spontaneous circulation at hospital transfer was evident in 24.9% of all cases. The survival to hospital discharge rate was 10.9%, and the 1-year survival rate was 6.9%. The survival to hospital discharge rate in the Utstein comparator group was 36.1%, and the 1-year survival rate was 27.2%. Five factors were associated with improved survival to hospital discharge: shockable rhythm, time from call to arrival at the patient less than 10 min, witnessed OHCA, age < 80 years, and male sex. CONCLUSION: This is the first OHCA study from Lithuania examining OHCA epidemiology and outcomes over a three year period. Routine OHCA data collection and analysis will allow us to track the efficacy of service improvements and should become a standard practice in all Lithuanian regions. TRIAL REGISTRATION: This research was registered in the clinicaltrials.gov database: Identifiers: NCT04784117, Unique Protocol ID: LITOHCA.

What happens in the shock room stays in the shock room? A time-based audio/video audit framework for trauma team performance analysis.

INTRODUCTION: A precise tool for analysis of trauma team performance is missing. OBJECTIVES: To create a framework for trauma team performance analysis and feedback. METHODS: An observational study in a level I trauma centre in Lithuania was performed from January 1 2017 to August 31 2017. Audio/video review process was used to evaluate technical and nontechnical performance of the trauma team. RESULTS: In total, 143 trauma team activations were analysed. The mean rate of completion for the primary survey based on Advanced Trauma Life Support principles was 68.5%. Technical steps of patient resuscitation were measured in seconds during first hour of the treatment. The T-NOTECHS scale mean score was 11.99 (SD 2.9). CONCLUSION: During the study period, we were able to measure the time needed for certain steps in trauma patient evaluation and management. Based on this analysis, a performance improvement program will be devised, including the HybridLab medical simulation, audio/video debriefing, and individualised feedback sessions.

Evaluation of volume status in a prehospital setting by ultrasonographic measurement of inferior vena cava and aorta diameters.

OBJECTIVES: The aim of this study was to evaluate the utility of ultrasonographic measurement of the diameter of the inferior vena cava (IVCD) and abdominal aorta (AAD) for assessing volume status. MATERIAL AND METHODS: This was a prospective, observational study. A total of 23 volunteers participated in the study. Each participant was selected randomly. All participants completed the 2016 Kaunas Marathon. Participants filed out a brief survey about their fluid intake (in standardised glasses) in the 24 h before the race and during the race. Participants underwent ultrasound measurements 10-40 min before the start of the race and 3-15 min after finishing the race. To visualize respiratory variation, M-mode was used, with the beam crossing the IVCD 2 cm from the right atrium. The AAD was measured 1 cm above the celiac trunk. IVCD in expiration (IVCDexp)/AAD was calculated by dividing the value of IVCDexp by the value of AAD. The findings were compared with difference in body mass index. RESULTS: The mean weight lost after the marathon was 2.93 kg (p < 0.001). Mean IVCD in inspiration (IVCDins) after the run was lower by 0.39 cm (p < 0.001) then before the run. Mean IVCDexp/AAD after the run was 0.24 cm lower than before the run (p = 0.03). Before and after the marathon, there was a statistically significant negative correlation in weight difference, with mean IVCDexp difference (p = 0.047). There was no statistically significant difference in caval index before and after running. CONCLUSION: Ultrasonographic assessment of IVCDexp could be useful in the evaluation of volume status.
