ASSESSMENT OF HEALTH-RELATED QUALITY OF LIFE IN POST-STROKE PATIENTS USING THE SS-QOL-12 SCALE
Main Article Content
Abstract
Background: Stroke is a leading cause of mortality and disability worldwide. Beyond survival, post-stroke care aims to improve and maintain health-related quality of life (HRQoL). In Vietnam, studies using specialized instruments such as the Stroke-Specific Quality of Life–12 (SS-QOL-12) remain limited. Objective: To determine the prevalence of impaired HRQoL and associated factors among post-stroke patients using the SS-QOL-12 scale. Patients and Methods: A descriptive cross-sectional study was conducted on 328 patients at least one month after stroke, admitted to 1A Hospital between October 2024 and June 2025. HRQoL was assessed using the SS-QOL-12; impairment was defined as a total score ≤195 after scale transformation. Multivariable logistic regression was applied to identify independent predictors. Results: Of 328 patients, 305 (92.98%) had impaired HRQoL. Compared with those without impairment, affected patients were older (63.0 ± 12.6 vs. 54.5 ± 11.1 years; p=0.0019), had a higher proportion aged ≥60 years (61.3% vs. 26.1%; p=0.0009), greater stroke severity (NIHSS 13.2 ± 5.4 vs. 9.4 ± 4.5; p<0.001), and more hospital-acquired infections (22.9% vs. 8.7%; p=0.010). Multivariable analysis identified four independent factors: age ≥60 years (adjusted OR 4.57; 95% CI 1.69–12.36), ischemic heart disease (OR 12.94; 95% CI 2.92–57.23), each 1-point increase in NIHSS (OR 1.11; 95% CI 1.04–1.19), and hospital-acquired infection (OR 2.90; 95% CI 1.20–7.00). Conclusions: The prevalence of impaired HRQoL among post-stroke inpatients was very high. Older age, ischemic heart disease, higher stroke severity, and hospital-acquired infections were significantly associated with worse HRQoL. Routine screening with SS-QOL-12 and targeted interventions are warranted in high-risk groups.
