Spontaneous intracerebral hemorrhage (sICH) is associated with high rates of morbidity and mortality. Neurosurgical clot evacuation is controversial but often a life saving maneuver in the setting of severe mass effect and cerebral herniation. Outcomes from large multicenter databases are sparsely reported. Patients who underwent craniotomy for evacuation of a supratentorial sICH between 2006 and 2017 were systematically extracted from the American College of Surgeons National Surgical Quality Improvement Program Participant Use Files. Our primary outcomes of interest were 30-day mortality, non-routine discharge disposition, and extended length of stay ([eLOS], defined as the top quartile for the cohort). Individual binary logistic regression models were constructed to query the associations between pre- and perioperative variables and each outcome. A total of 751 patients met the inclusion criteria. The 30-day mortality rate was 23.3% and increased from 2011 to 2017 (pooled OR 2.060 [95% CI 1.437 - 2.953]). Older age, morbid obesity, preoperative mechanical ventilation, preoperative systemic inflammatory response syndrome (SIRS) or septic shock, and thrombocytopenia were associated with mortality. Older age, race, and preoperative mechanical ventilation were associated with non-routine discharge. Patients who were mechanically ventilated or were insulin-dependent diabetics had greater odds of experiencing eLOS. A formula for estimating 30-day mortality was developed and found to have a strong linear association with actual mortality rates (R2 = 0.777, p = 0.002). Preoperative mechanical ventilation is a consistent predictor of poor outcomes following surgery for supratentorial sICH. Mortality is also influenced by older age, body habitus, SIRS, septic shock, and thrombocytopenia.
