Abstract Objective To assess possible long-term excess mortality and causes of death patients with chronic subdural hematoma (CSDH). Methods A retrospective study (1990–2015) adult ( n = 1133, median age 76 years old, men 65%) CSDH identified by ICD-codes verified medical records. All were followed until or the end 2017. Cumulative relative survival ratios risks (RER) estimated comparing patients’ that in entire regional matched population. The compared a separate reference group formed randomly choosing sex, age, calendar time controls (4 per each patient). Results follow-up was 4.8 (range 0–27 years), 710 (63%) died (median at 84 old). cumulative 1 year 9%, 5 18%, 10 27%, 15 37%, 20 48%. subgroup 206) no comorbidity had mortality. Excess related to poor modified Rankin score admission (RER 4.93) discharge 8.31), alcohol abuse 4.47), warfarin 2.94), ≥ 80 old 1.83), non-operative treatment 1.56), non-traumatic etiology 1.69). Hematoma characteristics recurrence unrelated Dementia most common cause among (21%) third (15%, p < 0.001). Conclusions Patients have continuous up after diagnosis. Patient-related strong association mortality, whereas specific CSDH-related findings do not. an increased risk for dementia-related
