This project has resulted in the most comprehensive set of clinical indicators that have ever been developed for use in UK general practice. In addition, it has started to field test these indicators so that primary care practitioners and managers can understand how feasible the indicators are to use and their scientific properties. However, and as with most leading-edge projects, we are left with some important questions about the use of indicators and the role of measurement in general practice unanswered. The final section outlines the key issues that need to be addressed to maximize the benefits and minimize the risks of introducing greater measurement to British general practice.
