Perioperative Infection After Aneurysmal Subarachnoid Hemorrhage : Risk Factors, Causative Pathogens, and Long-Term Outcomes
Copyright © Congress of Neurological Surgeons 2023. All rights reserved..
BACKGROUND AND OBJECTIVES: Nosocomial infections are the most common complication among critically ill patients and contribute to poor long-term outcomes. Patients with aneurysmal subarachnoid hemorrhage (aSAH) are highly susceptible to perioperative infections, yet it is unclear what factors influence infection onset and functional recovery. The objective was to investigate risk factors for perioperative infections after aSAH and relate causative pathogens to patient outcomes.
METHODS: Clinical records were obtained for 194 adult patients with aSAH treated at our institution from 2016 to 2020. Demographics, clinical course, complications, microbiological reports, and outcomes were collected. χ 2 , univariate, and multivariate logistic regression analyses were used to analyze risk factors.
RESULTS: Nearly half of the patients developed nosocomial infections, most frequently pneumonia and urinary tract infection. Patients with infections had longer hospital stays, higher rates of delayed cerebral ischemia, and worse functional recovery up to 6 months after initial hemorrhage. Independent risk factors for pneumonia included male sex, comatose status at admission, mechanical ventilatory use, and longer admission, while those for urinary tract infection included older age and longer admission. Staphylococcus , Klebsiella , and Enterococcus spp. were associated with poor long-term outcome. Certain pathogenic organisms were associated with delayed cerebral ischemia.
CONCLUSION: Perioperative infections are highly prevalent among patients with aSAH and are related to adverse outcomes. The risk profiles for nosocomial infections are distinct to each infection type and causative organism. Although strong infection control measures should be universally applied, patient management must be individualized in the context of specific infections.
