Performance of the adapted Diabetes Complications Severity Index translated to ICD-10.

OBJECTIVES: To assess the performance of the adapted Diabetes Complications Severity Index (aDCSI) translated to International Classification of Diseases, Tenth Revision (ICD-10) in predicting hospitalizations, mortality, and healthcare-associated costs. STUDY DESIGN: Retrospective closed cohort study based on secondary data analysis. METHODS: We translated the aDCSI to ICD-10 and calculated aDCSI scores based on health insurance claims data. To assess predictive performance, we used multivariate regression models to calculate risk ratios (RRs) of hospitalizations and mortality and linear predictors of cost. RESULTS: We analyzed a sample of 157,115 patients with diabetes mellitus. RRs of hospitalizations (total and cause specific) rose with increasing aDCSI scores. Predicting total hospitalizations over a 4-year period, unadjusted RRs were 1.22 for an aDCSI score of 1 (compared with a score of 0), 1.55 for a score of 2, 1.77 for a score of 3, 2.11 for a score of 4, and 2.72 for scores of 5 and higher. Cause-specific hospitalizations and mortality showed similar results. Costs clearly increased in each successive score category. CONCLUSIONS: Our study supports the validity of the aDCSI as a severity measure for complications of diabetes, as it correlates to and predicts total and cause-specific hospitalizations, mortality, and costs. The aDCSI's performance in ICD-10-coded data is comparable with that in International Classification of Diseases, Ninth Revision-coded data.

[Rationale and dissemination of "GP centered health care" ("HzV") in Germany]. / Rationale und Stand der hausarztzentrierten Versorgung in Deutschland.

BACKGROUND: In the face of demographic changes, the aging of the population, and the increase in chronic morbidity and complexity, efficient primary care is needed to ensure comprehensive and high-quality health care. The general practitioner (GP) can only cope with this task, if certain preconditions are met. OBJECTIVES: To strengthen primary health care, the German legislator added § 73b, "GP-centered health care" ("Hausarztzentrierte Versorgung", HzV) to the Social Code Book V. This article seeks to illustrate the rationale and general set-up of the HzV and to report on its dissemination. We discuss whether or not the HzV can promote the preconditions required. MATERIALS AND METHODS: Literature search, querying participants. RESULTS: Several elements of the HzV, such as lump-sum reimbursement, obligatory participation in structured quality circles, continuing education, and the qualification of non-medical health care assistants help to promote an environment that enables GPs to fulfill their new role. Considering all assured people and the Federal Republic as a whole, the distribution of the HzV is poor. However, a growing number of contracts (currently: 79) and participants (currently > 3.6 million) is expected. CONCLUSIONS: The establishment of efficient primary care is heavily promoted by the HzV. In future, ways must be found to overcome the inflexible borders between sectors and to integrate community-based health care, which truly focuses on the patients needs. The HzV can be seen as a starting point.
