Background
Within cardiopulmonary resuscitation external chest compressions (ECC) are of outstanding
importance. Frequent training in Basic Life Support (BLS) may improve the performance, but the
perfect method or environment is still a matter of research. The objective of this study was to
evaluate whether practical performance and retention of skills in resuscitation training may be
influenced by the gender composition in learning groups.
Methods
Participants were allocated to three groups for standardized BLS-training: Female group (F): only
female participants; Male group (M): only male participants; Standard group (S): male and female
participants. All groups were trained with the standardized 4-step-approach method. Assessment of
participants’ performance was done before training (t1), after one week (t2) and eight months later (t3)
on a manikin in the same cardiac arrest single-rescuer-scenario. Participants were 251 Laypersons
(mean age 21; SD 4; range 18-42 years; females 63%) without previous medical knowledge.
Endpoints: compression rate 90-110/min; mean compression depth 38-51 mm. Standardized
questionnaires were used for the evaluation of attitude and learning environment.
Results
After one week group F performed significantly better with respect to the achievement of the correct
mean compression depth (F: 63% vs. S: 43%; p = 0.02). Moreover, groups F and S were the only
groups which were able to improve their performance concerning the mean compression rate (t1:
35%; t3: 52%; p = 0.04). Female participants felt more comfortable in the female–only environment.
Conclusions
Resuscitation training in gender-segregated groups has an effect on individual performance with
superior ECC skills in the female-only learning groups.
Female participants could improve their skills by a more suitable learning environment, while male
participants in the standard group felt less distracted by their peers than male participants in the
male-only group.
