Abstract
PURPOSE: To examine health care utilization of people with multiple chronic diseases in The Netherlands compared to people with one chronic disease, and to identify different subgroups of multimorbid patients based on differences in health care utilization. METHODS: All patients diagnosed with one or more chronic diseases in 2008-2009 (N=17,443) were selected from the nationwide NIVEL Primary Care Database, and data on their GP contacts were included. Data on hospital admissions (from the Dutch Hospital Data database) and household size and income (from the Integral Household Incomes database 2010) were added. Chi-square-tests and multivariate regression analyses were performed to test for differences between multimorbid patients and patients with one chronic disease, and between subgroups of multimorbid patients derived from cluster analysis. RESULTS: Multimorbid patients (40% of the total sample) had more GP contacts, prescribed medications, and hospital admissions (all p<.0001) than patients with one chronic disease. The largest cluster of multimorbid patients (80%) was characterized by a relatively low level of health care utilization. Two smaller clusters comprised patients with a (very) high level of health care utilization - these people were mainly older, more often female, had a lower income, a smaller household size, and suffered from more chronic diseases. CONCLUSIONS: Among the vast majority of multimorbid patients health care utilization is only slightly higher compared to patients with one chronic disease. Extensive health care utilization among people with multimorbidity seems to be related to patient characteristics as well as illness characteristics.
