Brief description Hypertension is a major condition managed in general practice. The condition is under diagnosed and under treated. Where hypertension is treated, it is often with drugs that are expensive rather than with equally efficacious inexpensive drugs. Hypertension is associated with higher risk of stroke, coronary artery disease, cardiac failure, renal disease and peripheral vascular disease. Clear evidence-based information has been available for some years that provide reasonably guidelines to practitioners of the treatment thresholds for hypertension. However, the incorporation of this evidence into general practice has been slow. This project will build upon extensive pilot work to create a system to collect diagnostic, treatment and outcome data from general practice patients. The use of peer-compared feedback, particularly related to a readily understandable health outcome measure such as blood pressure, can change clinical behaviour when provided to the treating clinician. The aim of this project is to show whether or not training in the use of an evidence-based guideline to assist doctors in the decision of whether or not to initiate antihypertensive treatment, and to provide guidance on the type of treatment, leads to better outcomes than that of feedback alone. A cost-benefit analysis will clarify the impact of guideline implementation on health care costs. The incorporation into the cost-benefit analysis of patients perceptions of treatment by doctors using a guideline will show how such practice, compared with standard care, is valued by patients. While the project will focus on hypertension, the database members will continue to develop the research capability of the database, and expand it to incorporate a range of evidence-based information to improve the quality of care for other conditions. The database could achieve an expanding and sustainable influence on the quality of primary health care.
