This study evaluates a peer-training model for cardiopulmonary resusci
tation (CPR) instruction for laypersons. Forty-one Norwegian factory e
mployees were trained in CPR and given instructor training. These firs
t trainees then trained 311 co-workers. These employees then trained 8
73 family members and associates at home. The reference group consists
of employees in a Massachusetts commercial hotel trained in seven Ame
rican Red Cross (ARC): Adult CPR classes, The Norwegian home trainees
learned CPR using a cardboard training manikin and were trained by Nor
wegian factory employees who had learned CPR from co-workers, Trainees
were evaluated using skill sheets and a Laerdal Skillmeter(TM) maniki
n. The performance of the Norwegians trained at home by peers did not
differ from that of the ARC: Adult CPR trainees in six skills of the i
nitial sequence of CPR, The home trainees outperformed the ARC: Adult
CPR trainees in the proportion of compressions delivered correctly (P
= 0.032) and ventilations delivered correctly (P = 0.015), Peer traini
ng may provide CPR instruction comparable to training in CPR classes a
t lower cost and with potential to reach new population segments.
