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][3][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][7][8][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), in-hospital survival rate, and discharge survival rate.A retrospective observational study was conducted at Tenth People's Hospital of Tongji University.Patients were included based on the following criteria: adults (> 18 years) who experienced IHCA and received CPR in the emergency resuscitation room between February 1, 2021 and September 30, 2021, and between February 1, 2022 and September 30, 2022.Exclusion criteria were: 1) incomplete video recordings or failure to obtain necessary data; 2) patients with one of the following obvious and irreversible signs of death: decomposition, postmortem lividity, rigor mortis; 3) family refusal to participate in the study.Patients during the QCC activity period were not included.All patients were divided into pre-QCC and post-QCC groups based on their admission time.Informed consent was obtained from the families of all patients upon admission.
