26 How do guidelines and recommendations influence medical treatment?

 

Chronic diseases are treated differently in different regions. A number of factors affect the choice of treatment. The study will investigate the influence of clinical guidelines and recommendations have and how their use can be optimised.

Portrait / project description (ongoing research project)

First, possible treatment options will be identified for selected chronic diseases, and related clinical guidelines and recommendations will be analysed. Administrative claims data from a major health insurance provider will be used to investigate regional differences in treatment. Associations between the choice of treatment and the available clinical guidelines and recommendations will be analysed. We will examine the hypothesis that the better the quality of the guidelines and recommendations, and the better they are established, the less pronounced regional treatment differences will be. Finally, we will examine whether regional differences in treatment affect healthcare costs, hospital admissions and mortality.

Background

The utilisation of medical services varies considerably both over time and between regions. Reasons may include medical progress, people’s different needs and the varying importance assigned to preventive measures. Major regional differences may indicate underprovision or overprovision of healthcare to certain population groups. This has significant repercussions for population health and for healthcare costs – particularly where chronic diseases are concerned.

Aim

The aim of the study is to identify and describe regional differences in the treatment of chronic diseases. In particular, it will look at how clinical guidelines and recommendations affect the choice of treatment and how their usefulness can be increased.

Relevance / Application

The study will provide an overview of the clinical guidelines and recommendations available for the treatment of chronic diseases. It will show how these guidelines and recommendations affect the choice of treatment, and will point to areas for possible improvement, with the aim of counteracting the under- or overprovision of healthcare for the chronically ill.
