Examining the Influence of Social Interactions and Community Resources on Caregivers' Burden in Stroke Settings: A Prospective Cohort Study.

Since the introduction of the integrated care model, understanding how social interactions and community resources can alleviate caregivers' burden is vital to minimizing negative patients' outcomes. This study (n = 214) examined the associations between these factors and caregivers' burden in stroke settings. It used 3-month and 1-year post-stroke data collected from five tertiary hospitals. Subjective and objective caregivers' burdens were measured using Zarit burden interview and Oberst caregiving burden scale respectively. The independent variables examined were quality of care relationship, care management strategies for managing patients' behaviour, family caregiving conflict, formal service usage and assistance to the caregiver. Significant associations were determined using mixed effect modified Poisson regressions. For both types of burden, the scores were slightly higher at 3 months as compared to 1 year. Poorer care-relationship (relative risk: 0.81, 95% confidence interval (CI): 0.70-0.94) and adopting positive care management strategies (relative risk: 1.05, 95% CI: 1.02-1.07) were independently associated with a high subjective burden. Providing assistance to caregivers (relative risk: 2.45, 95% CI: 1.72-3.29) and adopting positive care management strategies (relative risk: 1.03, 95% CI: 1.02-1.04) were independently associated with a high objective burden. Adopting positive care management strategies at 3 months had a significant indirect effect (standardised β: 0.11, 95% CI: 0.01 to 0.20) on high objective burden at one year. Healthcare providers should be aware that excessive care management strategies and assistance from family members may add to caregivers' burden.
