Opportunities for clinician education in the pharmacotherapy of stable heart failure

Abstract

Abstract Introduction Heart failure (HF) is a commonly encountered clinical entity in the developed world, and is estimated to cost 660m euro annually to the Irish exchequer. Evidence supporting the benefit of multi disciplinary care in reduction of readmission rates has prompted the establishment of specialist HF clinics, resulting in improved medication adherence and early recognition and treatment of mild decompensation, thus averting the need for hospital admission. In contrast, the role of the hospital generalist and the general practitioner in the management of stable HF is under-emphasised despite evidence that optimal medical therapy reduces readmission and its attendant costs. The aim of this survey was to assess knowledge of pharmacotherapeutic options amongst generalists, and identify opportunities for education, in order to further optimise guideline-directed medical therapy while the patient awaits specialist input. Methods We distributed a 14 item questionnaire regarding indications for HF medications (as per ESC guidelines) to doctors in medicine and general practice throughout Ireland. Results There were 127 responses from 27 centres (117 analysed). Median years of practice was 4. Table 1 depicts the breakdown of clinicians who correctly identified HFrEF as an indication for each of the major drug classes. More than 20% of clinicians at all grades failed to identify HFrEF as an indication for beta blocker therapy. There was a higher level of knowledge amongst junior doctors in the prescription of mineralocorticoid receptor antagonists (p≤0.05) but no statistical difference in knowledge of other drug classes. Only 26% of participants who felt comfortable with initiation and up-titration of beta blockers (N=89) correctly identified an optimal target heart rate of less than 70 beats per minute. Twenty-four percent of respondents (N=28) were unaware of a specialist HF service that catered to their institution. Ninety-seven percent (N=113) felt that their practice would benefit from further education on HF pharmacotherapy. Conclusion The high prevalence of HF in Ireland and costs associated with admission for decompensation necessitates a sound knowledge of its management amongst generalists. Results of this survey suggest a need, and indeed a demand, for further education and support surrounding pharmacotherapy of stable heart failure.
