Abstract 261: Intermittently Encouraging Laypersons to Practice CPR Does Not Improve CPR Quality, Whereas Actual Practice Does Improve CPR Quality, 6 Months Post Training
Background: CPR quality varies considerably and skills deteriorate over time from initial training. Investigations suggest that frequent training may improve CPR skills. Few studies have tested methods to encourage laypersons to practice their skills post-training.
Objectives: We hypothesized that trained laypersons who receive intermittent encouragement to practice their CPR skills will perform faster and deeper chest compressions (CC); additionally, we hypothesized that those who actually practiced their skills will have improved CPR quality when tested 6 months post-training.
Methods: In a multicenter trial of CPR strategies, cardiac patient caregivers were trained in CPR. All subjects were contacted at 2 and 4 months post-training and randomized to receive encouragement to practice CPR (“prompting”) or no suggestion to practice (“no prompting”) via a self-reported method (telephone, email, etc). At 6 months post-training, CPR skills were assessed through a “surprise” home visit and subjects were asked if they practiced their skills. CPR performance was quantified on a CPR-manikin and analyzed using multivariable regression controlling for confounders.
Results: Subjects were enrolled from 02/2012-05/2014. 398 subjects consented to a skills check (180 in the prompting group, 183 in the control group, 35 lost to follow-up). Enrollees’ mean age was 51±14 years, and 73% were female. In an adjusted regression analysis, CC depth was 2.6±3.1 mm deeper among the prompted cohort (p=ns) and CC rate was 0.7±6.3 per min faster among those prompted (p=ns). Of those prompted, 56% reported practicing after prompting, while 44% of those not prompted reported practicing CPR skills after training. CC rate was 1.7 ± 3.2 per min faster among those who practiced their skills (p=ns). CC depth was 5.0 ±1.6 mm (95% CI: 1.8, 8.2) deeper among individuals who practiced their skills compared to those who did not practice (p<0.01).
Conclusions: Intermittent encouragement using self-reported preferred contact methods did not improve CPR quality, while CC depth improved among laypersons that actually practiced their skills. This work suggests that practicing improves CC depth and additional efforts are needed to facilitate practicing post-training among laypersons.
