Simulation-based CPR training for community health workers in Brazil: A pre-post intervention study

This study evaluated the effectiveness of simulation-based cardiopulmonary resuscitation (CPR) training for Community Health Workers (CHWs) in Brazil, hypothesizing that it would improve both theoretical knowledge and practical skills in emergency response. A single-group pre-post intervention study was conducted with 36 CHWs from Barrocas Municipality, Bahia. Participants underwent a 10-hour training program combining theoretical instruction aligned with AHA 2020 guidelines and hands-on mannequin simulations. Pre- and post-tests assessed knowledge using a 12-item multiple-choice questionnaire, while practical performance was evaluated through objective CPR metrics (compression depth, rate, and recoil). Data were analyzed using paired-sample t-tests. Twelve participants (33.3%) reported prior structured emergency care training. Post-test scores increased by 20% (mean correct answers: 7.5 ± 1.5 vs. 9.0 ± 1.2; p < 0.001), and most participants achieved recommended benchmarks for chest compression depth and rate during post-training assessment. Simulation-based training was associated with significant short-term improvements in CPR knowledge and performance among CHWs. These findings indicate that structured simulation may enhance emergency preparedness within primary care settings.
