Stroke survival after discharge from an acute-care hospital

Survival after a stroke is likely to be best for patients well enough to be sent home but the relative risk of dying if patients do not qualify for a home discharge has not been well studied. We investigated the survival prognosis after an initial stroke depending on the facility to which the patient was discharged after an acute initial stroke.

All patients were enrolled between July 1, 1987, and August 1, 1989, and were followed up to 4 years (mean of 24 months) until death, second stroke, or the end of the study.

Among 662 patients who were discharged alive after hospitalization with an initial stroke, 128 (19%) went to a nursing home, 17(3%) to a short-term hospital, 140 (21%) to a rehabilitation facility, and 375 (57%) went home (discharge destination unknown for 2 patients). Compared to patients sent home after taking age, sex, selected baseline comorbidities, length of hospital stay, and neurological deficits into consideration, results from Cox proportional hazards model indicated that patients sent to a nursing home had 2.6 times greater risk of dying (95% CI = 1.81-4. 15) while those who were discharged to a rehabilitation facility had a death hazards ratio of 1.1.

Mortality was greatest in the early months after discharge and decreased thereafter. Since the analysis was adjusted for age, sex, comorbidity, length of hospital stay, and number of neurological deficits, quality of care in a nursing home setting may account for the mortality difference but other factors such as social support network and living will instructions also need to be investigated.
