RESUMO
The present article describes the special features of an evaluation of research in mental health services in Germany. The experiences of the evaluation of flexible and integrated treatment options with a global treatment budget in psychiatric hospitals based on routine data of more than 70 statutory health insurance (SHI) funds (EVA64 study) are systematically presented. Using the EVA64 study as an example, recommendations for the use of claims data in the field of mental health services research and in general are derived. (1) First, the study and its use of claims data is described and classified. (2) The individual outcomes of the study are presented and evaluated in order to (3) derive criteria, identify strengths and suggest potential uses of claims data. (4) Finally, recommendations for the further development of claims data from SHI funds as a basis for evaluation are described.

Preventable chronic diseases account for the greatest burden in the German health system and statutory health insurance (SHI) funds play a crucial role in implementing and financing prevention strategies. On the contrary, the morbidity-based scheme to distribute financial resources from the Central Reallocation Pool among the different sickness funds may counteract efforts of effective prevention from an economic perspective. We assessed financial impacts of prevention from a sickness funds perspective in a retrospective controlled study. Claims data of 6,247,275 persons were analyzed and outcomes between two propensity-matched groups (n = 852,048) of prevention users and non-users were compared in a 4-year follow-up. Using a difference-in-differences approach, we analyzed healthcare expenditures, the development of morbidity, financial transfers from the Central Reallocation Pool, and contribution margins. The group of prevention users develops less morbidity (incidences and disease aggravations) compared to the control group. Healthcare expenditures increase in both groups within 4 years, whereas the increase is lower for prevention users compared to non-users (568.04 vs. 640.60, p < 0.0001). Taking morbidity-based financial transfers into account, the decrease in contribution margins is stronger for prevention users (- 188.44 vs. - 138.73, p < 0.0001). This study demonstrates an economic disincentive from a sickness funds' perspective. In the semi-competitive SHI market, sickness funds will be discouraged from effective prevention strategies if investments are not worth it financially. Their efforts and knowledge are, however, crucial for joint action to foster prevention over cure in the health system.

AIM: Cataract extraction is one of the most frequent surgeries in Germany. In most cases, the clouded natural lens is replaced by a hydrophobic or hydrophilic acrylic intraocular lens (IOL) implant. The most common long-term complication after cataract surgery is the development of a posterior capsule opacification (PCO). Although no precise real world data are available, published evidence suggests a lower risk for PCO development for hydrophobic acrylic IOLs compared to hydrophilic acrylic IOLs. Therefore, in the present study we assessed real world data on the impact of different IOL material types on the incidence of post-operative PCO treatment. SUBJECT AND METHODS: In this retrospective study, we included 3,025 patients who underwent cataract extraction and implantation of either an acrylic hydrophobic or hydrophilic IOL in 2010. We assessed clinical outcomes and direct costs in a 4-year follow-up period after cataract surgery from a statutory health insurance (SHI) perspective in Germany. RESULTS: PCO that required capsulotomies occurred significantly (p < 0.0001) less frequent in patients who had received a hydrophobic IOL (31.57% of 2,078 patients) compared to the group with hydrophilic IOL implants (56.6% of 947 patients) and costs per patient for postoperative treatment in a 4-year follow-up were 50.03 vs. 87.81 (i.e. 75% higher in the latter group, p < 0.0001). CONCLUSION: Considering the high prevalence of cataract, the economic burden associated with adverse effects of cataract extraction is of great relevance for the German SHI. Hydrophobic lenses seem to be superior regarding both medical and economic results.
RESUMO
BACKGROUND: In the field of colorectal cancer and other cancer entities, there is an ongoing trend to establish multidisciplinary treatment in specialised cancer centres. Little is known by now about the outcomes of this centralised and quality-driven treatment approach. In light of the increasing cost-benefit discussions, assessments of their impact seem to be necessary. This paper discusses positive effects of cancer centres with a particular focus on the multidisciplinary approach and its potential impact on survival outcomes of colorectal cancer patients. The study applies a Markov approach to assess the epidemiological impact of the cancer centre establishment and associated life years gained, both at a regional level and over time. MATERIALS AND METHODS: We conducted a systematic literature review to evaluate effects of multidisciplinary treatment in specialised cancer centres in the field of colorectal cancer. Applying the PRISMA scheme, 602 articles were assessed by title, abstract and full text. Finally, 10 publications met the inclusion criteria and were included in a meta-analysis. Using the example of the "Krebszentrum Nord" at the University Hospital in the federal state of Schleswig-Holstein, we assessed the impact of changes in survival rates at the regional level by simulating expected incidence, mortality and prevalence rates in a Markov model including detailed population data of Schleswig-Holstein. RESULTS: The meta-analysis revealed that multidisciplinary treatment in a cancer centre was associated with a 4.5â% reduction of mortality rates in colorectal cancer patients. The greatest benefits were found for patients in advanced disease stages. At the regional level, 106 life years could be gained through the centre for colorectal cancer until 2020, according to the assumptions of the simulation. CONCLUSION: The establishment of colorectal cancer centres is associated with positive outcomes for patients. However, the scarce evidence base underpins the need for additional studies to further examine the impact of centre building in colorectal cancer care. Cancer registries are a solid foundation for further research. Future requirements for oncological care can be derived from the predicted epidemiological development.
