Abstract
OBJECTIVE
Data on risk factors for otogenic intracranial complications including cerebral abscess have been limited. Using a nationwide database, the aim was to identify the factors related to mortality and delayed discharge.
STUDY DESIGN
Retrospective.
SETTING
Nationwide database using the Diagnostic Procedure Combination database.
MAIN OUTCOME MEASURES
Data of 145 patients were extracted from a Japanese inpatient database between 2012 and 2020. The main outcome was survival at discharge. In a subgroup analysis of the 137 surviving patients, the second outcome was delayed discharge.
RESULTS
The mortality rate was 5.5% (8 of 145). Logistic regression analyses identified intracerebral complications (adjusted odds ratio [OR], 3.09) and more than 2-day delay of the first surgery after admission (adjusted OR, 4.68) as risk factors for mortality. Specifically, consciousness level evaluated by the Japan Coma Scale (JCS) was significantly related to prolonged hospitalization or mortality: JCS I (adjusted OR, 3.40) and JCS ≥II (adjusted OR, 25.1).
CONCLUSIONS
Although otogenic intracranial complications are rare, and their mortality is decreasing because of the progress in imaging and clinical strategies, they remain the most severe complications of suppurative otitis media and/or cholesteatoma. Consciousness level at admission, comorbid diabetes mellitus, and a greater than 2-day delay of surgical intervention were related to prolonged hospitalization or mortality.
