    Aim Of The StudyMany hospitals have basic life support (BLS) training programmes, but the effects on the quality of chest compressions are unclear. This study aimed to evaluate the no-flow fraction (NFF) during BLS provided by standard care nursing teams over a five-year observation period during which annual participation in the BLS training was mandatory.MethodsAll healthcare professionals working at Dresden University Hospital were instructed in BLS and automated external defibrillator (AED) use according to the current European Resuscitation Council guidelines on an annual basis. After each cardiac arrest occurring on a standard care ward, AED data were analyzed. The time without chest compressions during the period without spontaneous circulation (i.e., the no-flow fraction) was calculated using thoracic impedance data.ResultsFor each year of the study period (2008-2012), a total of 1454, 1466, 1487, 1432, and 1388 health care professionals, respectively, participated in the training. The median no-flow fraction decreased significantly from 0.55 [0.42; 0.57] (median [25‰; 75‰]) in 2008 to 0.3 [0.28; 0.35] in 2012. Following revision of the BLS curriculum after publication of the 2010 guidelines, cardiac arrest was associated with a higher proportion of patients achieving ROSC (72% vs. 48%, P=0.025) but not a higher survival rate to hospital discharge (35% vs. 19%, P=0.073).ConclusionThe NFF during in-hospital cardiac resuscitation decreased after establishment of a mandatory annual BLS training for healthcare professionals. Following publication of the 2010 guidelines, more patients achieved ROSC after in-hospital cardiac arrest.Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.
