A pragmatic randomized trial of cardiopulmonary resuscitation training for families of cardiac patients before hospital discharge using a mobile application.
(Journal Article;Multicenter Study)
AIM OF THE STUDY: Since over 80% of sudden cardiac arrests occur in the home, cardiopulmonary resuscitation (CPR) training for family members of high-risk cardiac patients represents a promising intervention. The use of mobile application-based (mApp) CPR training may facilitate this approach, but evidence regarding its efficacy is lacking. METHODS: We conducted a multicenter, pragmatic, cluster-randomized trial assessing CPR training for family members of cardiac patients. The interventions were mApp (video, no manikin) and VSI (video + manikin). CPR skills were evaluated 6-months post-training. We hypothesized that chest compression (CC) rate from training with an mApp would be no worse than 5 compressions per minute (CPM) lower compared to VSI. RESULTS: From 01/2016 to 01/2018, we enrolled 1325 eligible participants (mean age 51.6 years, 68.2% female and 59.4% white). CPR skills were evaluated 6-months post-training in 541 participants (275 VSI, 266 mApp). Mean rate was 84.6 CPM (95% CI: 80.4, 88.6) in VSI, compared to 82.7 CPM (95% CI: 76.2, 89.1) in the mApp, and mean depth was 42.1 mm (95% CI: 40.3, 43.8) in VSI, compared to 38.9 mm (95% CI: 36.2, 41.6) in the mApp. After adjustment, the mean difference in CC rate was -2.3 CPM (95% CI -9.4, 4.8, p = 0.25, non-inferiority) and CC depth was -3.2 mm (95% CI -5.9, 0.1, p = 0.056). CONCLUSION: In this large prospective trial of CPR skill retention for family members of cardiac patients, mApp training was associated with lower CC quality. Future work is required to understand additional approaches to improve CPR skill retention. CLINICAL TRIAL REGISTRATION: URL: ClinicalTrials.gov, Identifier: NCT02548793.
