Abstract 13869: Self-Rated Health Predicts Healthcare Utilization in Heart Failure Patients
Background: Low self-reported physical functioning, as assessed by the 12-item Short Form Health Survey (SF-12), predicts increased healthcare utilization in primary care. However, the utility of a single-item general health question to predict healthcare utilization among heart failure (HF) patients is not known.
Methods: The risk of hospitalization and emergency department (ED) visits associated with self-reported measures of physical functioning was prospectively assessed among HF patients in the community from 10/2007-6/2010. Scores ≤25 on the SF-12 physical component indicated low physical functioning and the first question on the SF-12 was used to measure self-rated general health. Anderson-Gill modeling, which accounts for repeated events, was used to predict the risk of hospitalization and ED visits by physical functioning measures.
Results: Of 355 HF patients (mean age 73±13, 58% men), 51 reported low physical functioning and 48 reported poor general health (23 reported both). Over a mean of 1.4 years, 613 hospitalizations and 786 ED visits occurred. After adjustment, low physical functioning exhibited a trend toward increased hospitalizations and ED visits; however, self-rated general health better predicted healthcare utilization (Table). Poor general health conferred nearly a two-fold increased risk of both hospitalizations and ED visits, whereas fair general health was associated with nearly a 50% increased risk of both measures of healthcare utilization, as compared with good to excellent health.
Conclusion: Among HF patients in the community, self-rated general health better predicts increased hospitalizations and ED visits than self-reported physical functioning. Thus, in addition to clinical measures, the administration of the first question of the SF-12 may help identify patients likely to have high rates of healthcare utilization.
