Abstract

Objectives

This study aimed to describe health-related quality of life (HRQoL) 3 months and 1 year after stroke, compare HRQoL between dependent (modified Rankin scale [mRS] 3-5) and independent (mRS 0-2) patients, and identify factors predictive of poor HRQoL.

Methods

Patients with a first ischemic stroke or intraparenchymal hemorrhage from the Joinville Stroke Registry were analyzed retrospectively. Using the 5-level version of the EuroQol-5D questionnaire, HRQoL was calculated for all patients 3 months and 1 year after stroke, stratified by mRS score (0-2 or 3-5). One-year HRQoL predictors were examined using univariate and multivariate analyses.

Results

Three months after a stroke, data from 884 patients were analyzed; 72.8% were categorized as mRS 0-2 and 27.2% as mRS 3-5, and the mean HRQoL was 0.670 ± 0.256. At 1-year follow-up, 705 patients were evaluated; 75% were classified as mRS 0-2 and 25% as mRS 3-5, and the mean HRQoL was 0.71 ± 0.249. An increase in HRQoL was observed between 3 months and 1 year (mean difference 0.024, P .0001). Increasing age, female sex, hypertension, diabetes, and a high mRS were associated with poor HRQoL at 1 year.

Conclusions

This study described the HRQoL after a stroke in a Brazilian population. This analysis shows that the mRS was highly associated with HRQoL after stroke. Age, sex, diabetes, and hypertension were also associated with HRQoL, although not independently of mRS.
