Background Since the last decade, non-communicable diseases, most commonly
diabetes mellitus (DM2) have become the main threat to global health. Based on a
prevalence of 9 million diabetic patients per year, DM2 constitutes a
considerable medical and economic burden in Germany. The healthcare spending and
its cost drivers are not yet sufficiently known.
Aims of the study The primary objective of this study was to describe the
resource use in health care and the cost of DM2 treatment in Germany, focusing
on the most significant cost drivers and opportunities for cost-savings. The
secondary objective was to analyse the impact of technical progress on diabetes
care.
Methods A systematic literature search was conducted in PubMed and Embase.
Following the PRISMA guidance, the review identified the study design,
epidemiological approach, analytical perspective, and data collection approach
in each of the included studies.
Results From 1.965 records, the final sample included 41 articles. The
annual diabetes-specific direct costs of DM2 ranged from 542 € to 6.323
€ per patient. The most used method was the incremental or excess cost
approach (1.8-fold higher costs compared to individuals without DM2). Intangible
costs – such as psychological well-being - were randomly considered in
the existing cost-of-illness studies.Confirmed risk factors included physical inactivity, obesity, genetic
predispositions, and tobacco use.The major cost drivers are demographic change with aging, increasing obesity, the
availability of medications and therapies and the increased use of medical
services by patients.
Conclusion DM2, based on the results of this study, constitutes a
considerable medical and economic burden in Germany and has a serious impact on
the government health expenditures.
