Background Nurses are pivotal first responders in in-hospital cardiac arrest (IHCA), and timely, guideline-concordant BLS substantially improves survival. While deliberate practice (DP) enhances skill acquisition, the optimal retraining interval for maintaining long-term proficiency among novice nurses remains unclear. This study aimed to compare the effects of single versus repeated DP sessions on the 6-month retention of Cardiopulmonary Resuscitation (CPR) quality and knowledge. Methods A quasi-experimental study enrolled 148 novice nurses allocated to Single-DP group (baseline training only) a Repeated-DP group (baseline plus a 3-month booster session). CPR quality (compression depth, rate, chest recoil, compression fraction), theoretical knowledge, and overall skill scores were assessed at baseline, immediately after training, and 6-month follow-up. Generalized estimating equations (GEE) assessed group, time, and their interaction. Results A total of 148 novice nurses completed the study, with no significant differences in baseline characteristics. Immediately after training, the Single-DP group achieved higher scores in theoretical knowledge ( P = 0.001) and overall skill ( P = 0.011). At the 6-month follow-up, the Repeated-DP group demonstrated superior retention in raw performance metrics, maintaining significantly greater median compression depth (52.00 vs. 47.50 mm; P = 0.014) and higher overall skill scores (57.72 vs. 54.55; P < 0.001). However, GEE analysis ...
