Versorgung geriatrischer Krankheitsbilder unter ausgewählten ambulanten Facharztgruppen: Kombination von Befragungs- und GKV-Routinedaten zur Abbildung des Leistungsgeschehens.

BACKGROUND: In light of an aging population, the German health system faces the challenge of adapting regional health care structures to the changing care needs of geriatric patients. Since geriatric care is interprofessional, a structural analysis of the service providers involved is required. Therefore, the aim of this study is to determine the primary and joint care responsibilities for geriatric patients with specific characteristics, to estimate the associated effort for selected outpatient medical service providers and to identify resulting care concentrations. METHODS: The analysis includes six selected specialist disciplines in the outpatient sector and is based on two databases: 1) A representative survey among outpatient physicians related to geriatric care (n = 400) to examine both the primary geriatric care needs that professionals treat regularly and aggravating geriatric morbidity. 2) A claims data analysis determines services and efforts for approximately 300,000 geriatric patients for every year from 2014 to 2018. For the specialists included in the analysis, care concentration was determined by association analysis comparing the care efforts of outpatient physicians for patients with different geriatric characteristics. RESULTS: General practitioners, in particular, serve as primary care providers for all geriatric characteristics; there is no concentration of care on specific patient groups. Concentrations associated with care efforts and joint care responsibilities for patients with certain geriatric characteristics are found among the more specialized physician groups. Across all professions, the physicians surveyed believe that geriatric-specific immobility, depression, anxiety disorders and cognitive deficits make the provision of care more difficult. DISCUSSION: The results contribute to the understanding of primary and interdisciplinary care responsibilities of outpatient physicians related to the treatment of geriatric conditions and can thus represent an important basis for the structural planning of geriatric care. Nevertheless, it should be noted that within the scope of the analysis presented, only general practitioners and five specialist disciplines could be taken into account. Therefore, the considerations primarily allow initial conclusions about the care responsibility of outpatient physicians with regard to geriatric morbidity. To enable comprehensive structural planning, however, the analyses would have to be expanded to include all specialists involved in geriatric care. CONCLUSION: The joint care responsibility of outpatient physicians for specific geriatric patients underlines the relevance for interdisciplinary care models and the need for expansion of geriatric expertise in the outpatient sector. In view of the ageing population and an increase in morbidity, the planning of care structures should be based on the needs of geriatric patients and the associated expenses incurred by the various health care providers.
