[Development of an indicator set for the evaluation of the population-based integrated healthcare model 'Gesundes Kinzigtal' (Healthy Kinzigtal)]. / Entwicklung eines Indikatorensets zur Evaluation der Integrierten Versorgung Gesundes Kinzigtal.

INTRODUCTION: The project "INTEGRAL-10-year evaluation of the population-based integrated health care model 'Gesundes Kinzigtal' (Healthy Kinzigtal)" (ICM-GK) is funded by the Innovation Committee of the Federal Joint Committee (G-BA) (grant no. 01VSF16002). The evaluation is to be based on a set of indicators that can be captured in routine data. On the one hand, they can be used to assess ICM-GK programs that are program-specific and geared towards prevention and disease management. On the other hand, possible negative side effects of the ICM-GK, which is designed as a "shared savings contract", are to be examined by also observing care needs not covered by the ICM-GK contract. Since an indicator set for the evaluation of regional integrated care (IC) programs in Germany is not yet available, a suitable indicator set should be developed. METHODS: RESULTS: The methodological framework links the OECD concept for quality assessment of health systems with Kessner's tracer methodology. Disease groups with a high prevalence ("common diseases"), prevention potential and potential for improvement through IC were selected as tracers. The literature search resulted in 239 QIs and the QI database search in 293 QIs, which were supplemented by 21 QIs from the focus groups. Out of a total of 553 QIs, 251 QIs remained after removal of duplicates and comparison with the data basis. This preliminary QI set was reduced to 101 QIs by consensus. In addition, 48 health reporting indicators were supplemented which serve to classify regional quality results. The final QI set maps the following 19 disease categories/tracers: heart failure (16 QIs), myocardial infarction (4 QIs), CHD (10 QIs), stroke (6 QIs), metabolic syndrome (7 QIs of which 5 were diabetes-related), COPD (6 QIs), asthma (3 QIs), chronic pain (5 QIs), back pain (3 QIs), geriatrics (7 QIs), dementia (8 QIs), osteoporosis (3 QIs), rheumatism (3 QIs), multiple sclerosis (2 QIs), depression (4 QIs), antibiotic therapy (3 QIs), drug safety (1 QI), child care (5 QIs), early detection/prevention (5 QIs). 33 of these QIs are dedicated to five tracers that are not explicitly ICM-GK programs. Most QIs assess aspects of the effectiveness of care for the chronically ill and measure process quality. DISCUSSION: The set of indicators initially enables the quality assessment of regional, cross-indication care quality in the population-based integrated health care model 'Gesundes Kinzigtal' on the basis of routine data. Although the QI set focuses on effectiveness and process quality, it also includes QIs for preventive and acute care, coordination of care, patient orientation and safety, and outcomes. In contrast to other QI sets, both primary care and specialist health care and integrated, cross-sectoral and cross-professional care aspects have been considered. The benefits of the QI set for comparisons of regional quality and the evaluation of different IC programs remain to be tested. CONCLUSION: On the basis of a broadly based research and participatory development process, a set of indicators has been developed that enables comprehensive evaluation of the regional quality of care of cross-indication, integrated care models focusing on common diseases. In order to be able to increasingly evaluate aspects of care coordination and patient orientation, health promotion as well as nursing, palliative and emergency care in the future, it would be helpful if routine data were collected or made accessible in these areas as well.

Study protocol for a quasi-experimental claims-based study evaluating 10-year results of the population-based integrated healthcare model 'Gesundes Kinzigtal' (Healthy Kinzigtal): the INTEGRAL study.

INTRODUCTION: Patients often experience interface problems when treated by different specialists and in different healthcare sectors. Integrated care concepts aim to reduce these problems. While most integrated healthcare models focus on individual diseases, the integrated care model 'Gesundes Kinzigtal' applies a population-based approach and addresses the full spectrum of morbidities for a population defined by area of residence-the Kinzigtal. A special feature of the model is the joint savings contract between the regional management company and the statutory health insurers. The INTEGRAL study aims at assessing the effectiveness of 'Gesundes Kinzigtal' under routine conditions in comparison to conventional care over a period of 10 years in order to understand the benefits but also the potential for (unintended) harms. METHODS AND ANALYSIS: Database Claims data from statutory health insurance funds 2005-2015. The evaluation consists of a quasi-experimental study, with Kinzigtal as intervention region, at least 10 further regions with a similar population and healthcare infrastructure as primary controls and an additional random sample of insurees from the federal state of Baden-Württemberg as secondary controls. Model-specific and 'non-specific' indicators adopted from the literature and enriched by focus group interviews will be used to evaluate the model's effectiveness and potential unintended consequences by analysing healthcare utilisation in general. Temporal trends per indicator in the intervention region will be compared with those in each control region. The overall variation in trends for the indicators across all regions provides information about the potential to modify an indicator due to local differences in the healthcare system. ETHICS AND DISSEMINATION: Ethic Commission of the Faculty of Medicine, Philipps-University Marburg (ek_mr_geraedts_131117). Results will be discussed in workshops, submitted for publication in peer-review journals and presented at conferences. TRIAL REGISTRATION NUMBER: DRKS00012804.
