[Primary and secondary data on dementia care as an example of regional health planning].

Background: Health service planning that takes into account as far as possible the regional needs and regional discrepancies is a controversial health issue in Germany.

Objectives: In a pilot scheme, we tested a planning process for regional healthcare services, based on the example of dementia care. The aim of this article is to present the strengths and limitations of this planning process.

Materials And Methods: We developed an indicator set for dementia care based on routine regional data obtained from two German statutory health insurance companies. Additionally, primary data based on a questionnaire sent to all GPs in the area were evaluated. These data were expanded through the addition of official socio-demographic population data. Procedures and evaluation strategies, discussion of the results and the derivation of planning measures followed, in close agreement with a group of local experts.

Results: Few epidemiological data on regional variations in health care planning are publicly available. Secondary data from statutory health insurance companies can be assessed to support the estimation of regional health care needs, but interpretation is difficult. The use of surveys to collect primary data, and the assessment of results by the local health board may facilitate interpretation and may contribute towards more valid statements regarding regional health planning.

Conclusions: Despite the limited availability of data and the considerable efforts involved in data analysis, the project demonstrates how needs-based health service planning can be carried out in a small region, taking into account the increasing demands of the local health care providers and the special local features.
