The retention of cardiopulmonary resuscitation skills.

Although a great emphasis has recently been placed on training both the medical profession and the general public in cardiopulmonary resuscitation (CPR), studies have demonstrated that retention of resuscitation skills is poor. Although CPR certification is generally valid for a 1- to 2-year period, evaluation of trainees at all levels has demonstrated a marked lack of proficiency over this course of time. This paper reviews the studies that have disclosed this lack of skills retention, as well as proposed solutions and reinforcement techniques. CPR course content and certification criteria must be appropriate to maximize retention as well as learning. To this end a simplification of basic life-support training curricula is recommended.
