18 Knowing the unknowns: what we forget in CPR S. Donnelly, 1 D. McKendrick, 2 A. Lee 3 and J.

It is challenging to provide effective cardiopulmonary resuscitation (CPR) in the highly pressured environ- ment of a cardiac arrest and there is an observed variation in the quality of CPR provided. This audit assesses the advanced life support (ALS) knowledge of members of the resuscitation team, looking specifically at recall of key facts that have been proven to positively affect outcome at cardiac arrest. Methods To assess knowledge of ALS, a questionnaire was designed using the Resuscitation Council UK Guidelines 2015. Individual questions covered facts that had been proven to positively influence outcome at cardiac arrest (early recognition and call for help, early CPR and early defibrillation). This audit was registered with the local clinical effectiveness unit as an audit, and the Health Research Authority online toolkit determined that NHS REC approval was not required. Members of the resuscitation team at Dr Gray’s Hospital, Elgin, volunteered to complete the questionnaire. After completion, feedback on responses was given and individuals were provided with correct referenced answers. Individuals repeated the questionnaire two weeks later to see if there was an improvement in knowledge. Results Thirty-eight individuals took part in the initial audit and 24 of these also took part in the repeat audit. The aver- age questionnaire score improved significantly (p < 0.001) from 63.5% for the initial audit to 83.3% after the feedback intervention. Initially, key facts such as correct compression depth (34.2%), compression rate (34.2%) and correct time for rotating the CPR giver (18.4%) were not well recalled. This later improved to 75.0%, 95.8% and 50.0%, respectively. Discussion There was a variation in the ALS knowledge of members of the resuscitation team, where some key facts which might influence outcome in cardiac arrest were not well recalled. Despite some team members already being highly trained (valid completion of ALS), they did not initially perform significantly better than others who had not completed an ALS course. There was a significant improvement in scores after a short knowledge refresher. Current recommendations from the International Liaison Committee on Resuscitation state that there is improved learning from low dose, frequent learning events compared to a comprehensive learning event that occurs infre- quently [2]. Using this approach, frequent assessment could be integrated into the daily work routine of the resuscitation team to help aid knowledge recall. References 1. Resuscitation Council (UK).
