Risk factors for postoperative pneumonia following intracranial aneurysm surgery: a propensity score matching analysis
Authors' conclusion
Six risk factors for POP after intracranial aneurysm surgery were identified in this study, some of which are modifiable.
Study context
- Population
- Adults (≥ 18 years) undergoing intracranial aneurysm surgery, January 2019 to July 2022668 matched analysed
- Participants
- 1,115 adults
- Exposure
- Postoperative pneumonia (POP) vs no POP
- POPn = 334
- No POPn = 334reference
- Outcome
- Independent risk factors for POP
Methodological details1:1 propensity-score matched, single hospital
- 1:1 propensity-score matched
- Single hospital
Main finding
As reported in the abstract
Independent risk factors for POP (multivariate logistic regression)
- Preoperative antimicrobial prophylaxis
- Operative duration ≥ 4 h
- Indwelling gastric tube
- Intensive care unit (ICU) admission on the day of surgery
- Postoperative use of analgesics or sedatives
- White blood cell (WBC) count ≥ 10,000 cells/µL
- After 1:1 propensity score matching
Observational data: associations, not effects.
