Insights
Stroke survivors often experience reduced quality of life in the first year. Key factors include symptom severity, functional disability, and individual characteristics, with support systems offering a buffer.
Area of Science:
- Neurology
- Public Health
- Rehabilitation Medicine
Background:
- Stroke significantly impairs neurological and functional abilities.
- Health-related quality of life (HRQOL) is notably reduced in the first year post-stroke.
Purpose of the Study:
- To identify critical factors influencing HRQOL in stroke survivors within the first year.
- To explore the interplay between symptoms, functional status, and HRQOL.
Main Methods:
- Integrative review of literature from January 2013 to December 2024.
- Searches conducted in PubMed, CINAHL, and PsycINFO, adhering to PRISMA guidelines.
- Methodological quality assessed using Johns Hopkins Nursing Evidence-Based Practice criteria.
Main Results:
- Twenty-two studies (predominantly observational) were included.
- Symptom severity (depression, anxiety, fatigue, stroke severity), functional disability (mobility), and individual factors (age, sex, education, resilience) negatively impacted HRQOL.
- Environmental factors (social support, rehabilitation access) acted as protective buffers.
Conclusions:
- Stroke survivors face significant risks to their quality of life in the first year.
- HRQOL is primarily influenced by symptom burden and functional limitations, moderated by individual and environmental contexts.
- Findings support interventions targeting symptom management, functional recovery, and personalized support.
Abstract:
Background: Stroke significantly impacts neurological and functional abilities, reducing health-related quality of life (HRQOL) within the first year poststroke. Aim: The review aimed to identify key factors influencing HRQOL among stroke survivors during their first year of stroke. Methods: Guided by Ferrans et al.'s HRQOL model and using Whittemore and Knafl's integrative review methodological strategy, PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO were searched to examine the available literature from January 2013 to December 2024. Study selection followed the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses; methodological quality was appraised using the Johns Hopkins Nursing Evidence-Based Practice. Results: Twenty-two studies met the inclusion criteria, predominantly level III observational designs (cross-sectional and prospective cohorts). The most salient factors influencing HRQOL during the first year poststroke were symptom severity (depression, anxiety, insomnia, fatigue, stroke severity), functional disability (mobility, extremity function), and individual factors (older age, female sex, lower education, lower resilience), which predicted poorer HRQOL, while environmental factors (social/community support, rehabilitation access) appeared to buffer the impact of disability. Evidence suggests the presence of mediated pathways in which symptoms affect functional status, which in turn shapes health perceptions and overall health-related quality of life (HRQOL), while individual and environmental characteristics function as moderating factors. Conclusion: Stroke survivors are at risk of poor quality of life during the first year after stroke. HRQOL is strongly driven by symptom severity and functional limitations, influenced by individual and environmental contexts. The conceptual model of HRQOL provided a better understanding of stroke survivors' experiences. Findings support targeted interventions focused on symptom management, functional rehabilitation, and individualized support.
