To determine the leading causes of death in intracerebral hemorrhage (ICH) survivors, we used administrative data from 3 large US states to identify adult survivors of a first-time spontaneous ICH and track all hospital readmissions resulting in death.

We performed a longitudinal analysis of prospectively collected claims data from hospitalizations in California (2005–2011), New York (2005–2014), and Florida (2005–2014). Adult residents admitted with a nontraumatic ICH who survived to discharge were included. Patients were followed for a primary outcome of any readmission resulting in death. The cause of death was defined as the primary diagnosis assigned at discharge. Multivariable Cox proportional hazards and multinomial logistic regression were used to determine factors associated with the risk for and cause of death.

Of 72,432 ICH survivors (mean age 68 years [SD 16], 48 …
