[Maintenance of chest compressions skill in cardiopulmonary resuscitation in primary health care professionals: Quasi-experimental study].

Objective: To validate the efficacy of brief CPR training with dual feedback to maintain the ability to perform quality chest compressions.

Materials And Methods: Quasi-experimental study with two groups to evaluate a brief theoretical training followed by a practice with manikin with feedback; Participants: 155 health and non-health professionals from 5 primary care health centers of urban area (43 losses); Main measurements: Characteristics of compressions that were measured before and after the brief training and their maintenance at 3 and 6 months according to the study group. The effect of training and maintenance of skills were analyzed using multiple linear regression models.

Results: 155 participants were included, mean age 39.7 years (SD=12.0) with 82.7% female. The training effect had an improvement in mean compression depth (pre-post difference: 3.5, P<.001), total compressions with adequate depth (pre-post difference: 0.2, P<.001) and Total Compressions with Adequate Rhythm (pre-post difference: 0.4, P<.001). The second phase was completed by 112 participants (72.2%). Compression skills declined at 3 months and were lower at 6 months, although the loss of skills was not statistically significant between the two groups.

Conclusions: An individualized, brief training action with feedback immediately improves the quality of compressions. The progressive loss of skills from 3 to 6 months is not relevant.
