Stroke-attributable nursing home use

Abstract

Objective: To estimate 1) among patients with stroke, nursing home use attributable to stroke, and 2) the savings in nursing home use, assuming strokes were prevented.

Methods: All confirmed cases of first stroke among Rochester, Minnesota, residents from 1987 through 1989 (n = 290) and one nonstroke control of same gender and similar age for each patient were followed up in provider-linked medical records and State of Minnesota nursing home files until emigration, death, or December 31, 1994. Data included disability and place of residence at baseline (i.e., data of stroke for each patient and their corresponding control), length of follow-up, cumulative incidence of nursing home admission, proportion of follow-up spent in a nursing home, and number of nursing home days.

Results: Before baseline, patients and controls were similar in the level of disability (mean Rankin = 1.7 for patients and 1.6 for controls) and the proportion in a nursing home (11% for both groups). Among those not in the nursing home at baseline, 5-year cumulative incidence of first admission was 48% for cases versus 20% for controls. Survival was significantly shorter for cases than for controls; the proportion of follow-up spent in the nursing home was 20% for cases versus 11% for controls. When controlling for survival, cases experienced an average of 110 (95% CI, 63 to 156) more nursing home days per person than controls in the first five years. When nursing home use during differential survival was included, the difference in nursing home days between cases and controls was no longer significant(p = 0.16).

Conclusions: Stroke prevention would result in fewer cases admitted to the nursing home, older age at first admission, and a smaller proportion of remaining life spent in the nursing home, but stroke prevention would not result in fewer nursing home days.
