Abstract

Patients experiencing out-of-hospital cardiac arrest (OOHCA) during the weekend are less likely to survive to hospital admission than those experiencing OOHCA on weekdays. We aimed to determine whether the survival rates of in-hospital cardiac arrest (IHCA) were lower on weekends than on weekdays. We comprehensively reviewed the records of patients who experienced IHCA at CBNUH between 2018 and 2020. A total of 861 IHCAs occurred during the study period; these data included recurrent IHCA cases, as some patients experienced more than one IHCA. Of these, 739 IHCA cases were included in the survival analysis, and the survival rate was 65.2%, which is higher than the rate reported in a previous study. There were no differences in the survival rate between weekdays and weekends. Additionally, the time of day at which IHCA occurred and pre-IHCA intubation status did not affect survival. Patients in wards were less likely to survive than those in intensive care units (60.0% vs. 66.0%). Although pre-IHCA intubation did not show any added value in preventing sudden cardiac arrests, meticulous patient care and monitoring in terms of intra- or extrapulmonary oxygen therapy is needed, as is the promotion of cardio-pulmonary-cerebral resuscitation (CPCR) equipment availability and quick rescuer responses for patients with IHCA. Our find-ings may be of value in improving CPCR guidelines and monitoring patients at risk of IHCA.
