Use of Video in Telephone Triage in Out-of-Hours Primary Care: Register-Based Study.

Background: Out-of-hours primary care (OOH-PC) is challenging due to high workloads, workforce shortages, and long waiting and transportation times for patients. Use of video enables triage professionals to visually assess patients, potentially ending more contacts in a telephone triage contact instead of referring patients to more resource-demanding clinic consultations or home visits. Thus, video use may help reduce use of health care resources in OOH-PC. Objective: This study aimed to investigate video use in telephone triage contacts to OOH-PC in Denmark by studying rate of use and potential associations between video use and patient- and contact-related characteristics and between video use and triage outcomes and follow-up contacts. We hypothesized that video use could serve to reduce use of health care resources in OOH-PC. Methods: This register-based study included all telephone triage contacts to OOH-PC in 4 of the 5 Danish regions from March 15, 2020, to December 1, 2021. We linked data from the OOH-PC electronic registration systems to national registers and identified telephone triage contacts with video use (video contact) and without video use (telephone contact). Calculating crude incidence rate ratios and adjusted incidence rate ratios (aIRRs), we investigated the association between patient- and contact-related characteristics and video contacts and measured the frequency of different triage outcomes and follow-up contacts after video contact compared to telephone contact. Results: Of 2,900,566 identified telephone triage contacts to OOH-PC, 9.5% (n=275,203) were conducted as video contacts. The frequency of video contact was unevenly distributed across patient- and contact-related characteristics; it was used more often for employed young patients without comorbidities who contacted OOH-PC more than 4 hours before the opening hours of daytime general practice. Compared to telephone contacts, notably more video contacts ended with advice and self-care (aIRR 1.21, 95% CI 1.21-1.21) and no follow-up contact (aIRR 1.08, 95% CI 1.08-1.09). Conclusions: This study supports our hypothesis that video contacts could reduce use of health care resources in OOH-PC. Video use lowered the frequency of referrals to a clinic consultation or a home visit and also lowered the frequency of follow-up contacts. However, the results could be biased due to confounding by indication, reflecting that triage GPs use video for a specific set of reasons for encounters.

Simulation-based team training in time-critical clinical presentations in emergency medicine and critical care: a review of the literature.

BACKGROUND: The use of simulation-based team training has increased over the past decades. Simulation-based team training within emergency medicine and critical care contexts is best known for its use by trauma teams and teams involved in cardiac arrest. In the domain of emergency medicine, simulation-based team training is also used for other typical time-critical clinical presentations. We aimed to review the existing literature and current state of evidence pertaining to non-technical skills obtained via simulation-based team training in emergency medicine and critical care contexts, excluding trauma and cardiac arrest contexts. METHODS: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Before the initiation of the study, the protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database. We conducted a systematic literature search of 10 years of publications, up to December 17, 2019, in the following databases: PubMed/MEDLINE, EMBASE, Cochrane Library, and CINAHL. Two authors independently reviewed all the studies and extracted data. RESULTS: Of the 456 studies screened, 29 trials were subjected to full-text review, and 13 studies were included in the final review. None of the studies was randomized controlled trials, and no studies compared simulation training to different modalities of training. Studies were heterogeneous; they applied simulation-training concepts of different durations and intensities and used different outcome measures for non-technical skills. Two studies reached Kirkpatrick level 3. Out of the remaining 11 studies, nine reached Kirkpatrick level 2, and two reached Kirkpatrick level 1. CONCLUSIONS: The literature on simulation-based team training in emergency medicine is heterogeneous and sparse, but somewhat supports the hypothesis that simulation-based team training is beneficial to teams' knowledge and attitudes toward non-technical skills (Kirkpatrick level 2). Randomized trials are called for to clarify the effect of simulation compared to other modalities of team training. Future research should focus on the transfer of skills and investigate improvements in patient outcomes (Kirkpatrick level 4).

Major Differences in the Use of Protocols for Dispatcher-Assisted Cardiopulmonary Resuscitation Among ILCOR Member Countries.

INTRODUCTION AND PURPOSE: Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) increases the rate of bystander cardiopulmonary resuscitation (CPR). DA-CPR is recommended by resuscitation councils globally and it has been shown that the general public expects to receive pre-arrival instructions while waiting for help. A scientific advisory from the American Heart Association identifies standardized and structured DA-CPR protocols as important to increase bystander CPR rates. This study aims to investigate whether different International Liaison Committee on Resuscitation (ILCOR) member countries use DA-CPR protocols and to compare protocol contents between countries. METHODS: All resuscitation councils forming ILCOR were inquired by email to provide a copy of their DA-CPR protocol, and to state whether this protocol was used by all emergency dispatch centers in their country. The collected protocols were translated into English, and content was compared. RESULTS: A total of 60 countries were contacted (response rate: 83%). Of these, 46% stated to have a nationwide protocol, 30% reported to use local protocols, and 24% did not use a protocol. Overall, 54% provided a copy of their protocol. All translated protocols asked the rescuer to check for responsiveness and breathing, 35% to activate phone speaker function, half contained notes about agonal breathing and 59% included notes about integrating an automated external defibrillator. CONCLUSION: Almost one quarter of ILCOR member countries did not use a protocol for DA-CPR. Half of the protocols included notes about agonal breathing. Activation of phone speaker function and protocolled encouragements during CPR were rarely included.

Basic life support training: Demonstration versus lecture - A randomised controlled trial.

INTRODUCTION: Basic life support (BLS) and the use of an automated external defibrillator (AED) improve survival from cardiac arrest. The gold standard for teaching BLS/AED is yet to be identified. The aim of this study was to compare the learning outcome of an instructor-led demonstration with a formal lecture for introducing BLS/AED skills. We hypothesized that a demonstration was superior to a lecture. METHODS: First year-medical students were randomised to either a demonstration or a lecture using PowerPoint® Presentation for skill introduction during European Resuscitation Council BLS/AED courses. Participants were skill-tested after training and required to perform all skills correctly to pass the test. Finally, all participants were asked to state their preferred teaching method. RESULTS: Overall, 247 participants were included in the analysis (demonstration group: 124, lecture group: 123). Pass rate was 63% in both groups, p = 1.00. Both groups performed median compression rates within guidelines recommendations, p = 0.09. Mean compression depth was 55 mm (10 mm) in the demonstration group compared with 52 mm (10 mm) in the lecture group, p = 0.05. Median tidal volume was 265 (192, 447) ml and 405 (262, 578) ml, p < 0.001, respectively. The lecture group was 3 s faster at initiating BLS, p < 0.001. In total, 226 (91%) participants preferred demonstration on a manikin for introducing BLS/AED. CONCLUSION: There was no statistically significant difference in pass rate when comparing a demonstration with a lecture for introducing BLS/AED. The lecture group was slightly faster at initiating BLS. Most participants preferred a demonstration as introduction.

Three-Month Retention of Basic Life Support with an Automated External Defibrillator Using a Two-Stage versus Four-Stage Teaching Technique.

INTRODUCTION: Resuscitation training increases bystander's ability to perform basic life support (BLS) with an automated external defibrillator (AED) immediately after training. However, several studies indicate that resuscitation skills decay rapidly. METHODS: This study evaluates retention of BLS/AED skills three months after an initial study comparing acquisition of BLS/AED skills among laypersons immediately after training with a two-stage versus four-stage teaching technique. RESULTS: There was no difference in retention of BLS/AED skills (pass rate 10.8% versus 10.9%, respectively, p=1) three months after training. Total average number of skills adequately performed (of 17) was 13.3 versus 13.7 among laypersons trained with a two-stage and a four-stage technique, respectively. No difference was found in quality of chest compressions and rescue breaths between the two groups. CONCLUSION: Three months after training, this study found no difference in retention of BLS/AED skills among laypersons taught using a two-stage compared to a four-stage teaching technique.

In a bed or on the floor? - The effect of realistic hospital resuscitation training: A randomised controlled trial.

INTRODUCTION: In-hospital cardiac arrest has a poor prognosis and often occurs in patients lying in a hospital bed. A bed mattress is a soft compressible surface that may decrease cardiopulmonary resuscitation (CPR) quality. Often hospital CPR training is performed with a manikin on the floor. AIM: To study CPR quality following realistic CPR training with a manikin in a bed compared with one on the floor. METHODS: We conducted a randomised controlled study. Healthcare professionals were randomised to CPR training with a manikin in a hospital bed or one on the floor. Data on CPR quality was collected from manikins. The primary outcome measure was chest compression depth. RESULTS: In total, 108 healthcare professionals (age: 40years, female: 94%) were included. The mean chest compression depth was 39mm (standard deviation (SD): 10), for the bed group compared with 38mm (SD: 9) for the floor group, p=0.49. A post hoc analysis showed that regardless of the training method, the participants who optimised their working position by jumping onto the bed or lowering the bed had a median chest compression depth of 39mm (25th-75th percentiles: 33-45) compared with 29mm (25th-75th percentiles: 23-41) for participants who did neither, p=0.04. CONCLUSION: There was no significant difference in chest compression depth between healthcare professionals who trained CPR on a manikin in a hospital bed compared with one on the floor. Chest compression depth was too shallow in both groups. Irrespective of the training method, participants who optimised their working position performed deeper chest compressions.

A novel protocol for dispatcher assisted CPR improves CPR quality and motivation among rescuers-A randomized controlled simulation study.

BACKGROUND: Emergency dispatchers use protocols to instruct bystanders in cardiopulmonary resuscitation (CPR). Studies changing one element in the dispatcher's protocol report improved CPR quality. Whether several changes interact is unknown and the effect of combining multiple changes previously reported to improve CPR quality into one protocol remains to be investigated. We hypothesize that a novel dispatch protocol, combining multiple beneficial elements improves CPR quality compared with a standard protocol. METHODS: A novel dispatch protocol was designed including wording on chest compressions, using a metronome, regular encouragements and a 10-s rest each minute. In a simulated cardiac arrest scenario, laypersons were randomized to perform single-rescuer CPR guided with the novel or the standard protocol. PRIMARY OUTCOME: a composite endpoint of time to first compression, hand position, compression depth and rate and hands-off time (maximum score: 22 points). Afterwards participants answered a questionnaire evaluating the dispatcher assistance. RESULTS: The novel protocol (n=61) improved CPR quality score compared with the standard protocol (n=64) (mean (SD): 18.6 (1.4)) points vs. 17.5 (1.7) points, p<0.001. The novel protocol resulted in deeper chest compressions (mean (SD): 58 (12)mm vs. 52 (13)mm, p=0.02) and improved rate of correct hand position (61% vs. 36%, p=0.01) compared with the standard protocol. In both protocols hands-off time was short. The novel protocol improved motivation among rescuers compared with the standard protocol (p=0.002). CONCLUSIONS: Participants guided with a standard dispatch protocol performed high quality CPR. A novel bundle of care protocol improved CPR quality score and motivation among rescuers.
