Secondary school students tend to overestimate their CPR-skills

terug naar publicaties

Purpose of the study: To increase survival after sudden cardiac arrest more people should be able to provide cardiopulmonary resuscitation (CPR). Annual short CPR training sessions in secondary schools can contribute to achieve that goal. This study reports on the students self-perceived skills and the objectively measured values in a test scenario.

Materials and methods: Included were 85 secondary school students participating in a Meuse-Rhine Euregion CPR training program EMuRgency. Training consisted of 1½ hour hands-on training: each student having an own manikin with medical students as CPR-instructors. Before and after the CPR training a questionnaire was completed on self-assessment of their CPR confidence. After the training students performed CPR on a manikin in a test-scenario.

Results: Demographic variables included: mean age: 13.9 (SD:0.8), male: 49.4%, educational level being classified as: 1.higher level education (58.8%), 2.preparatory scholarly education (41.2%). Before training, 18.8% reported to be confident in performing chest-compressions at the correct rate as compared to 74.1% post-training. Corresponding correct compression depth figures were 10.6% and 75.3% respectively. The results from the test-scenario showed an average compression rate of 112.7 p min−1 (95%CI 109.5–115.9 SD:15.0) and compression depth of 41.8 mm (95%CI 39.8–43.8 SD: 9.3). Only 42% of the students scored a frequency between 100 and 120 min−1 and only 21.2% scored a depth between 50 and 60 mm. Average compression depth increased by school year, 1st year: 36.4 mm, 2nd year: 43.6 mm, 3rd year: 47.3 mm (p = 0.001).

Conclusions: Even a short CPR training increases confidence about resuscitation skills in secondary school students, but also leads to overestimation as found when tested two weeks after. However an improvement is observed per higher school year as suggested by increased compression depth. Repeated training will improve resuscitation performance, becoming more in line with the already high self-perceived ability for CPR.
