Research summary
When someone has a cardiac arrest in hospital, doctors and nurses try to restart their heart through resuscitation. Sometimes these efforts are successful, and sometimes they’re not. Previous research in the U.S. found that hospitals which tend to continue resuscitation efforts for longer—even when the patient doesn’t survive—often have better overall outcomes. But that study didn’t fully account for differences in the types of patients treated at each hospital, which could affect the results.
This study will used data from UK hospitals to see if the same pattern holds true here. Specifically, we will uses detailed records from the National Cardiac Arrest Audit (held by ICNARC), which include the exact start and end times of resuscitation attempts.
The main research question is:
Do hospitals that spend more time trying to resuscitate patients who don’t survive tend to have better outcomes overall for cardiac arrest patients?REC name
