Are there changes in medical specialist contacts after transition to a nursing home? an analysis of German claims data

BACKGROUND: Provision of ambulatory care by medical specialists for nursing home residents (NHR) is discussed to be inadequate in Germany, however with only incomplete evidence on this topic. We wanted to know whether the transition to a nursing home is associated with a general decrease in medical specialist care and therefore compared contact rates before and after institutionalization. METHODS: Claims data of 18,779 newly admitted NHR in 2013 were followed for the whole year prior to and up to two years after admission. The frequencies of contacts to specialists were assessed and stratified by sex, age, care level, dementia diagnosis and chronic conditions. Multivariate analyses were conducted to identify predictors for contacts to specialists. RESULTS: One year after institutionalization the most pronounced decrease was found in contacts with ophthalmologists (38.4% vs. 30.6%) whereas with most other specialties only small changes were found. The only specialty with a large increase were neurologists and psychiatrists (27.2% vs. 43.0%). Differences depending on sex and age were rather small while NHR with dementia or a higher care level had lower contact rates after institutionalization. Before institutionalization most patients were referred to a specialist by a general practitioner (61.7–73.9%) while thereafter this proportion decreased substantially (27.8–58.6%). The strongest predictor for a specialist contact after admission to a nursing home was a contact to a specialist before (OR 8.8, CI 7.96–9.72 for contacts to neurologists or psychiatrists). A higher nursing care level and a higher age were also predictors for specialist contacts. CONCLUSIONS: Relevant decreases of ambulatory specialist care utilization after institutionalization are restricted to ophthalmologists. NHR of higher age and higher nursing care level had a lower chance for a specialist contact. The assessment of the adequacy of the provided care after institutionalization remains inconclusive due to little investigated but assumable changes in care needs of NHR. The decreased coordination of care by general practitioners after institutionalization conflicts with health policy goals.
