Background. Published research offers clear pointers to the management of h
eart failure; however, the evidence for implementation into practice is sub
-optimal.
Aim. To identify the salient barriers to adopting evidence-based management
of heart failure in the community.
Method. Structured interviews were used to elicit the views of a stratified
sample of 100 general practitioners (GPs) about the diagnosis and treatmen
t of heart failure. Responses to three heart failure case scenarios provide
d an indication of the degree to which GPs' knowledge of heart failure and
trial results might be applied to diagnosis and treatment intentions.
Results. Participants were generally well aware of clinical trials that sho
wed that prognosis could be improved by treatment, but trial results appear
ed to have little influence on treatment intentions in the three case scena
rios. The major barriers to optimum management were the difficulties of dif
ferential diagnosis and the perceived properties of angiotensin-converting
enzyme inhibitors (ACE-I) relative to diuretics. In the case scenarios, les
s than 30% reported that they would undertake basic investigations, such as
chest Xray or haemoglobin, or prescribe ACE-I. Over 70% perceived diuretic
s to be a useful diagnostic tool. The most frequent reasons for not prescri
bing ACE-I were the perceived inconvenience and risks of adverse effects (4
1%) and the view that most patients can be managed successfully on diuretic
s alone (27%). Over two-thirds of the sample were dissatisfied with the qua
lity of information accompanying heart failure patients discharged from hos
pital.
Conclusion. Facilitating evidence-based management of heart failure in the
community requires further support for GPs in the form of additional traini
ng in the diagnosis of heart failure and the optimum use of both ACE-I and
diuretics, and by improved communication between GPs and hospital doctors o
n a case-by-case basis.
