INTRODUCTION: The primary aim of the disease management program (DMP) for patients with
COPD is to improve health outcomes and thereby to reduce overall costs. Six years after its
introduction in Germany, no consensus has yet been reached as to whether the DMP has been
effective in reaching these goals. The objective of the study was an evaluation of the DMP for COPD
in Bavaria using routinely collected subject medical records. METHODS: A longitudinal population-based
study, comparing the total DMP population of up to 86,560 patients with a stable cohort
of 17,549 subjects over a period of 5 years. The effect of subject dropout in the cohort is further
estimated by means of inverse probability weighting. RESULTS: The proportion of subjects in the
total population who were prescribed and received treatment with oral corticosteroids declined at
a constant rate of 1.0% per year (P < .001). The proportion of subjects who were given a prescription
for theophylline decreased at a constant rate of 2.0% per year (P < .001). By 2012,15.6%
of the total population and 26% of the cohort had undergone self-management education. While the
proportion of smokers in the total population remained constant because of the effect of newly
enrolled subjects, the proportion of smokers decreased significantly even after dropout adjustment,
from 29% to 21%. The occurrence of exacerbations decreased steadily at a rate of 0.9% (total
population) or 0.7% (cohort) per year. While the occurrence of emergency hospital admissions
decreased in the total population, an increase was observed within the cohort. CONCLUSIONS:
Summarizing all results leads to the suggestion that the German DMP for COPD has been effective
in enhancing the quality of care in regard to an improved adherence to guidelines, pharmacotherapy,
exacerbations, and self-management education. However, the DMP was not able to prevent an
increase in emergency hospital admissions for the stable population in the cohort
