The aim of the Leicestershire Fracture Index is to bring together data from routine sources: inpatient, outpatient and A&E, into a single patient-centred database and in so doing promote the use of outpatient systems. The index should then be able to provide accurate information on incidence and outcomes and hence be a reliable foundation for audit, a basis for estimating needs and activities and a sampling frame for research. The development is particularly timely in view of the increased sophistication of contract specification with a move from simple speciality totals to detailed service provision and the introduction of effectiveness and outcome measures for outpatient services.
