Inpatient Postoperative Mortality: Comparing Patients Hospitalized Preoperatively to Those Having Elective Surgery
Main finding · In-hospital deathResult — go to the resultRelative risk 0.13 95% CI 0.12–0.14Authors' conclusion
Results of previous studies of all-cause perioperative mortality should not be applied to patients having elective major surgery because most deaths (approximately 95%) and most cases (70%) are in patients having nonelective major surgery ( i.e. , already admitted to the hospital or undergoing trauma-related surgery).
Study context
- Population
- Adults undergoing major diagnostic or therapeutic surgery in Florida in 2021 and 2022, hospitalized 2 or more midnights
- Participants
- 1,245,537 hospitalizations
- Exposure
- Elective vs nonelective major surgery
- Outcome
- In-hospital death (share of deaths in the nonelective group)
Methodological detailspopulation-based, statewide administrative data

As reported in the abstract
Observational data: associations, not effects.
Further findings
Diversity of procedures (ICD-10-PCS codes) among patients who died
- Hundreds of different ICD-10-PCS codes occurred commonly among patients who died, in both groups
Safety
AKI, hospital-acquired pneumonia, MACE, infection (sensitivity analyses)
- RRs all less than 1.0 in the elective group
