[Effects of a regional intervention to promote asthma guidelines implementation]

Despite of asthma guidelines existing for years, secondary data analysis shows insufficient medical care of asthmatics in Germany. The aim of the present study was to improve asthma guideline adherence by promoting guidelines implementation.

We analyzed prospectively pre- and post-interventional medical care of a sample of 127 asthmatics who were recruited by physicians working in ambulatory care and in hospitals of the Region Neckar-Alb, Germany. Data came primarily from patient interviews by phone. Our intervention to promote guidelines implementation consisted of following methods: 1. analyzing regional asthma care followed by a feedback performance report to physicians; 2. delivering asthma patient diaries and peak flow meters to study patients; 3. developing and adapting regionally asthma guidelines for adult asthmatics in the Region of Neckar-Alb; 4. promoting guidelines utilization by publishing the adapted guidelines in a scientific journal, direct mailing of a short version to the practitioners, and boosting the guidelines at regional CE meetings; 5. reanalyzing asthma care of the study cohort and the implementation of the guidelines 13 months after the beginning of the intervention. We studied the effect of the intervention using a qualitative model comprising 18 quality indicators measuring the proportion of patients who were treated in accordance to the guidelines. To compare pre- and post-interventional proportions we used the McNemar test for statistical analysis.

The proportion of asthmatics treated in accordance to the guidelines improved significantly from 48 % to 57 %. The increase was mainly due to an improvement of guidelines adherence within the field of promoting asthma self-management and continuous monitoring of patients (42 % pre- and 57 % post-intervention), whereas guidelines adherence in pharmacotherapy improved only from 53 % to 56 %.

The proportion of asthmatics treated in accordance to guidelines can be improved by using a multifaceted regional approach to promote guidelines implementation.
