Does management by heart failure specialists in a dedicated program reduce hospitalizations and improve exercise capacity in patients with heart failure compared to prior management?
Management of heart failure patients by specialists in a dedicated program significantly reduces hospitalizations and improves functional capacity compared to standard care.
BACKGROUND: Most patients with heart failure are currently managed by physicians with little specific expertise in heart failure. This management system has been associated with evidence of suboptimal care, such as high rates of hospital readmission and underuse of ACE inhibitors. The current study was undertaken to determine whether hospitalization rates and functional outcomes are improved when patients are managed by physicians with special expertise in heart failure working in a dedicated heart failure program. METHODS AND RESULTS: All patients with heart failure referred to the Vanderbilt Heart Failure and Heart Transplantation Program between July 1994 and June 1995 were identified. Annual hospitalization rates, medications, and peak exercise capacity before and after referral were compared in patients followed for >30 days. A total of 187 patients were referred during the index time period, of whom 134 (72%) were followed for >30 days. During the year before referral, 94% of the patients were hospitalized (210 cardiovascular hospitalizations) versus 44% of the patients during the year after referral (104 hospitalizations) (53% reduction) (P<.01). Hospitalizations for heart failure decreased from 164 to 60 for all patients regardless of follow-up duration and decreased from 97 to 30 (69% reduction) for patients followed at least 1 year after referral. Eighty-eight of the patients were able to exercise at the time of referral. Peak exercise VO2 in this group increased from 12.8+/-4.7 to 15.7+/-4.8 mL x min(-1) x kg(-1) (P<.01) by 6 months after referral. Loop diuretic doses were on averaged doubled during the first 6 months after referral. CONCLUSIONS: These findings suggest that patients with heart failure have fewer hospitalizations for heart failure and are significantly more functional when managed by heart failure specialists working in a dedicated heart failure program rather than by physicians with limited expertise in heart failure.
