Information needs in a provider market: a case-study of ENT

In the light of the White Paper Working for patients, this study addresses two questions: first, whether the current pattern of service use is a valid surrogate for the assessment of the service needs of a population; second, given that information systems which will provide accurate cost per case information are several years from being implemented, what differences might be made to a specialty budget by the adjustment of case costs by use of different case-mix measures. ENT has been chosen as a case study because of its relative 'market potential'. The study addresses the first question by examining the variations in the current level and type of service use across Districts in a Region. The large variation in utilization across Districts, both in total and for different degrees of case complexity, suggests that the current pattern of service use is a poor indicator of need. The second part of the study examines a Unit which has large inflows of complex patients. Adjusting for case-mix, however, produces a comparatively small effect on the overall specialty budget, whether the adjustment is made using the BUPA schedule of surgical procedures or using diagnosis-related groups. In the light of these results, it is suggested that the current emphasis on accurately costing case-mix could be misplaced, and that more resources should be diverted to scrutinizing the appropriateness of service use to health needs and priorities, in line with the aims of the NHS reforms.
