Current Medical and Social Conditions and Outcomes of Hospitalized Heart Failure Patients　― Design and Baseline Information of the Cohort Study in Hiroshima ―

Background: Information regarding current medical and social conditions and outcome of Japanese heart failure (HF) patients is needed. Methods and Results: The registry and follow-up study regarding the medical and social conditions and outcomes of hospitalized heart failure patients (REAL-HF) is maintained by 8 regional core hospitals, which provide an interprofessional team approach for HF patients, in Hiroshima Prefecture. We planned to enroll all adult patients hospitalized with symptomatic HF (congestive HF and/or low output syndrome) in 1 year from March 2017. We registered the clinical characteristics of each patient, including physical activity (able to walk independently), during the indexed hospitalization. Information regarding living circumstances, cognitive function test, questionnaire for quality of life (QOL), and interprofessional team approaches was also collected. For patients discharged home, we planned to follow all-cause death, all-cause unscheduled readmission, and the conditions of outpatient cardiac rehabilitation and home nursing-care services at 3 and 12 months after discharge. A total of 1,218 patients has been registered initially. Follow-up is ongoing, and data analysis is expected to be completed in 2019. Conclusions: The REAL-HF will provide a significant database on the current real conditions of hospitalized HF patients in a local district of Japan, elucidating medical and social risk factors of worsened QOL and prognosis.
