A Mixed-Methods Study of Social Determinants and Self-care in Adults With Heart Failure

Abstract

Background The burden of heart failure (HF) is unequally distributed among population groups. Few study authors have described social determinants of health (SDoH) enabling/impeding self-care. Aim The aim of this study was to explore the relationship between SDoH and self-care in patients with HF. Methods Using a convergent mixed-methods design, we assessed SDoH and self-care in 104 patients with HF using the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) and the Self-Care of HF Index v7.2 with self-care maintenance, symptom perception, and self-care management scales. Multiple regression was used to assess the relationship between SDoH and self-care. One-on-one in-depth interviews were conducted in patients with poor (standardized score ≤ 60, n = 17) or excellent (standardized score ≥ 80, n = 20) self-care maintenance. Quantitative and qualitative results were integrated. Results Participants were predominantly male (57.7%), with a mean age of 62.4 ± 11.6 years, with health insurance (91.4%) and some college education (62%). Half were White (50%), many were married (43%), and most reported adequate income (53%). The money and resources core domain of PRAPARE significantly predicted self-care maintenance (P =.019), and symptom perception (P =.049) trended significantly after adjusting for other PRAPARE core domains (personal characteristics, family and home, and social and emotional health) and comorbidity. Participants discussed social connectedness, health insurance coverage, individual upbringing, and personal experiences as facilitators of self-care behavior. Conclusion Several SDoH influence HF self-care. Patient-specific interventions that address the broader effects of these factors may promote self-care in patients with HF.
