Impact of quality control circles on the quality and outcomes of in-hospital emergency cardiopulmonary resuscitation

High-quality cardiopulmonary resuscitation (CPR) is crucial for survival after cardiac arrest. Despite regularly updated guidelines and extensive training efforts, the quality of CPR performed by healthcare providers remains suboptimal [1]. The survival rate for cardiac arrest is still very low, with only 1% to 6% of out-of-hospital cardiac arrest (OHCA) patients and less than 17% of in-hospital cardiac arrest (IHCA) patients surviving [2-4]. Quality control circles (QCC) originated as a business management concept and were most popular in the 1980s [5]. China Hospital Association for Quality Management was established in 2013, and it has been reported that QCC activities have gradually been implemented in the domestic healthcare field in recent years, with significant benefits for improving healthcare quality [6-9]. However, we have not found any studies on the impact of QCC on the quality of emergency CPR. Therefore, to investigate the effect of QCC on the quality of CPR in the emergency department, we conducted this study to compare the quality and outcomes of CPR in emergency patients before and after QCC implementation. Our aim was to determine whether QCC can improve the quality of emergency CPR, thereby enhancing the return of spontaneous circulation (ROSC), Hospital of Tongji University. Patients were included based on the folCPR in the emergency resuscitation room between February 1, 2021 and
