Patient Perspectives on the Burden of Heart Failure with Preserved Ejection Fraction in a US Commercially Insured and Medicare Advantage Population: A Survey Study.

Background: Patient-reported health related quality of life (HRQOL) is not routinely assessed in clinical practice. Little is known about health status outcomes reported by patients with heart failure with preserved ejection fraction (HFpEF) in non-clinical trial settings. Purpose: To better understand patient burden of HFpEF in terms of HF-specific functional and symptom status, HRQOL, healthcare resource utilization (HCRU) and costs in a US-based commercial and Medicare Advantage insured population. Patients and methods: We conducted a cross-sectional survey of patients with HFpEF and linked their survey and administrative claims data. Consenting, eligible patients completed a survey that included the 23-item Kansas City Cardiomyopathy Questionnaire (KCCQ-23) and the PROMIS Global Health-10 (GH-10) questionnaire, as well as clinical and demographic questions. HF medication use, HCRU and costs during the 12-month baseline period before the survey were determined from claims data. Generalized linear regression was used to assess the associations between baseline characteristics and the KCCQ-23 overall summary score. Results: Of 598 survey respondents with survey and claims data, 54.7% were female with mean age 74.0 years. The KCCQ-23 overall summary and clinical summary scores were 64.8 and 63.0, respectively, and the GH-10 physical and mental health summary scores were 39.9 and 45.5. Factors related to lower KCCQ-23 overall summary scores were HF treatment and symptom changes during the past 4-weeks before the survey, hospital admission during the past year, low household income, high comorbidity index, and morbid obesity (BMI>40). Total all-cause healthcare costs were $38,243 during the year prior to the survey, of which 42% were HF-related. Conclusion: Patient-reported outcome measure scores indicated impairment due to HF symptoms and physical limitations in this real-world sample of patients with HFpEF, highlighting a need to assess patient-reported outcomes as well as the clinical and economic outcomes traditionally assessed by clinicians, health systems and payers.
