How frequently should paediatric cardiopulmonary resuscitation skills be taught

### Clinical bottom line As a newly appointed Education and Simulation Fellow in a tertiary paediatric hospital, I am interested in using simulation to provide paediatric resuscitation training to staff. I wondered how frequently staff should undergo resuscitation training to ensure optimum retention of cardiopulmonary resuscitation (CPR) skills. Should responders to paediatric arrests ( population ) receive resuscitation training ( intervention ) more frequently than national guidelines recommend ( comparator ) to ensure optimum retention of CPR skills ( outcome )? We searched PubMed using the terms: ‘(frequency OR frequent OR interval OR timing) AND (training OR train OR education OR programme) AND (resuscitation OR CPR OR cardiopulmonary resuscitation OR basic life support training OR chest compression) AND (skills retention OR retain)’. Searches were conducted in September 2020. PubMed yielded 159 results. Studies involving laypeople were excluded. We did not exclude studies that assessed CPR skills on adult manikins given the need for paediatric providers to respond to adolescent emergencies. Thirty-one papers were identified for abstract review and eleven papers underwent …
