A randomized trial of video self-instruction in cardiopulmonary resuscitation for lay persons

Abstract

BackgroundCardiopulmonary resuscitation (CPR) improves outcomes after cardiac arrest. Much of the lay public is untrained in CPR skills. We evaluated the effectiveness of a compression-only CPR video self-instruction (VSI) with a personal manikin in the lay public.MethodsAdults without prior CPR training in the past year or responsibility to provide medical care were randomized into one of three groups: 1) Untrained before testing, 2) 10-minute VSI in compressions-only CPR (CPR Anytime, American Heart Association, Dallas, TX), or 3) 22-minute VSI in compressions and ventilations (CPR Anytime). CPR proficiency was assessed using a sensored manikin. The primary outcome was composite skill competence of 90% during five minutes of skill demonstration. Evaluated were alternative cut-points for skill competence and individual components of CPR. 488 subjects (143 in untrained group, 202 in compressions-only group and 143 in compressions and ventilation group) were required to detect 21% competency with compressions-only versus 7% with untrained and 34% with compressions and ventilations.ResultsAnalyzable data were available for the untrained group (n = 135), compressions-only group (n = 185) and the compressions and ventilation group (n = 119). Four (3%) achieved competency in the untrained group (p-value = 0.57 versus compressions-only), nine (4.9%) in the compressions-only group, and 12 (10.1%) in the compressions and ventilations group (p-value 0.13 vs. compressions-only). The compressions-only group had a greater proportion of correct compressions (p-value = 0.028) and compressions with correct hand placement (p-value = 0.0004) compared to the untrained group.ConclusionsVSI in compressions-only CPR did not achieve greater overall competency but did achieve some CPR skills better than without training.

Cardiopulmonary resuscitation (CPR) psychomotor skills of laypeople, as affected by training interventions, number of times trained and retention testing intervals: A dataset derived from a systematic review

“…This dataset (available in the accompanying Supplementary Excel Spreadsheet file) summarises, in 28 tables, the psychomotor skill data extracted from 31 primary peer-reviewed articles that met the inclusion criteria for the related systematic review [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32]. The psychomotor skills for which data were extracted and reported were: compression rate, compression depth, duration of interruptions to compressions, chest recoil, hand placement, proportion of adequate or ’correct’ compressions, ventilation volume, compression-to-ventilation ratio, duty cycle and overall skills.…”

Public willingness, attitudes and related factors toward cardiopulmonary resuscitation: A grounded theory study

“…Situational and social contexts are also important considerations. Studies have shown that rescuers’ gender, occupation, CPR training experience, and income level were associated with the public's attitudes toward performing CPR (Godfred et al, 2013; Shams et al., 2016). In addition, the public's attitudes of bystander CPR may be influenced by cultural or psychosocial variables, which require further investigation (Lu et al., 2016).…”

Einfluss eines Erste-Hilfe-Kurses für Medizinstudierende auf notfallmedizinische Basiskompetenzen

“…Auch Online-Tutorials vor BLS-Trainings resultierten in signifikant besseren praktischen Maßnahmen der Teilnehmenden 145. Der Lerneffekt bei Video-basiertem CPR-Training ist umstritten und aktuell Gegenstand mehrerer Forschungen 144,[146][147][148][149]. Bei diesen Beispielen sind vor allem die gute Durchführbarkeit und die Ressourcen-Einsparung ein wesentlicher Vorteil.…”
