Predictors of do-not-attempt-resuscitation decisions in patients with infratentorial or large supratentorial intracerebral hemorrhages and consequences thereafter: a register-based, longitudinal study in Sweden.

OBJECTIVES

Do-not-attempt-resuscitation (DNAR) decisions for patients with infratentorial or large supratentorial intracerebral hemorrhages (ICHs) pose clinical and ethical challenges. We aimed to investigate factors associated with DNAR decisions in patients with infratentorial or large (≥30 mL) supratentorial ICH, and differences in complications, treatment, and mortality.

MATERIALS &

METHODS

This longitudinal, observational study comprised all patients treated for ICH at three stroke units in Gothenburg, Sweden, between November 2014 and June 2019. Patients were identified in the local stroke register, and additional data were collected from medical records and national registries. Mortality rates were followed 1 year after incident ICHs. Factors associated with DNAR decisions, and one-year mortality were explored.

RESULTS

Of 307 included patients, 164 received a DNAR decision. Most (75%) decisions were made within 24 h. DNAR decisions were associated with higher age, pre-stroke dependency, stroke severity, and intraventricular hemorrhage. Patients without DNAR decisions received thrombosis prophylaxis, oral antibiotics, and rehabilitative evaluations more frequently. The one-year survival probability was 0.16 (95% confidence interval [CI] 0.11-0.23) in patients with DNAR decisions, and 0.87 (95% CI 0.81-0.92) in patients without DNAR decision. DNAR decisions, higher age, stroke severity, hematoma volume, and comorbidities were associated with increased one-year mortality. Thrombosis prophylaxis and living alone were associated with a lower hazard.

CONCLUSION

The majority of DNAR decisions for patients with infratentorial or large supratentorial ICH were made within 48 h. Higher age, pre-stroke dependency, high stroke severity, and intraventricular hemorrhage predicted receiving a DNAR decision. DNAR decisions were strongly associated with increased short- and long-term mortality.
