Outcome predictors
Table 6 summarises the results of the univariate logistic regression analyses for three main outcomes: return to theatre, hospital stay (>21 days) and ND. Combined neurosurgical and ENT interventions did not result in lower morbidity. The size of an intracranial abscess (≥10mm) was found be associated with a significantly increased likelihood of return to theatre (odds radio 7, confidence interval 1.09-45.1, p=0.041), while the remaining predictors were not found to be significant.
