Cardiac arrest & resuscitation
In-Hospital Cardiac Resuscitation During Widespread Resident Resignations in South Korea
Authors' conclusion
In this retrospective cohort study, the crisis period was associated with fewer prolonged CPR attempts, with no significant differences in ROSC or survival outcomes.
Study context
- Population
- Adults ≥18 years who underwent cardiopulmonary resuscitation (CPR) for in-hospital cardiac arrest (IHCA) at a single tertiary teaching hospital in South Korea, March 2023–February 2025469 IHCA events
- Participants
- 383 adults
- Exposure
- IHCA during vs before workforce crisis
- Outcome
- ROSC and TOR without ROSC, analysed as competing events over CPR duration
Methodological detailssingle-centre, competing-risk analysis

Main finding
As reported in the abstract
Crisis period not associated with return of spontaneous circulation (ROSC), aHR
0.93
95% CI 0.72–1.19
Crisis period associated with higher hazard of termination of resuscitation (TOR) without ROSC, aHR
1.66
95% CI 1.14–2.42
Observational data: associations, not effects.
Secondary outcomes
Overall IHCA incidence (incidents per 1000 admissions)
- Did not differ between periods (2.30 vs 2.50 incidents per 1000 admissions)
- P = 0.36
CPR duration
- Median CPR duration in both periods (minutes)
- 8
CPR exceeding 35 minutes
- Less frequent during vs before the crisis: 12 of 180 events [6.7%] vs 38 of 289 events [13.1%]
- P = 0.03
Neurological and survival outcomes
- Did not differ statistically
Standardized cumulative incidence of TOR without ROSC · 35 minutes
- Higher cumulative incidence; absolute risk difference (percentage points)
- 4.9
