Enabling clinical governance: a primary care audit of prescribing for heart failure in central Auckland, New Zealand

There is little evidence that treatment advances have improved the prognosis of heart failure in the community. One explanation is the failure of doctors to undertake necessary prescribing. Reports elsewhere how a modified Delphi approach, based on the RAND Health Services utilisation study method, was used to produce audit criteria for necessary prescribing for systolic heart failure in New Zealand (NZ) general practice. Reports experience of applying these criteria in late 1999 to the medical notes of a random sample of 70 patients with heart failure, as defined by a recorded diagnosis in 30 practices in central Auckland, NZ. Use of the audit criteria was feasible and appears valid, although the methods used to apply them need to be simplified to be of use as a practical means of promoting clinical governance. The small patient sample demands caution in interpreting the results. However, uncommon yet plausible findings, such as the high frequency of ACE inhibitor prescribing for heart failure, deserve further investigation.
