Cardiac arrest & resuscitation
Code Blue blindspots: mapping nursing exposure to cardiac arrests
Authors' conclusion
Even in high-incidence wards, most nurses experience long, irregular intervals between cardiac arrest events-periods long enough for CPR and resuscitation skills to decay.
Study context
- Population
- Code Blue (in-hospital cardiac arrest (IHCA)) activations at a tertiary care hospital, January 2023 through December 2024
- Participants
- 9 vs 10,000
- Exposure
- Standard schedules vs All modeled schedules
- Standard schedulesn = 9
- All modeled schedulesn = 10,000
- Outcome
- Number of Code Blue events encountered per nursing schedule and intervals between exposures
- Follow-up
- Two years
Methodological detailssingle-centre, spatial-temporal analysis, schedule simulation
- Single-centre
- Spatial-temporal analysis
- Schedule simulation
