Nonemergent craniotomy surgical site infection: a retrospective cohort study.

Background: The incidence of surgical site infection after craniotomy (SSI-CRAN) varies widely and is associated with major consequences. The aim of this study is to estimate the SSI-CRAN rate at the neurosurgery department of a tertiary center and to establish its risk factors.

Methods: All consecutive adult patients who underwent elective craniotomy for tumor resection at a tertiary center from January 2018 to October 2019 were retrospectively assessed.
