Effect of a health service integration on health care use of patients with alcohol disorders

Abstract

Abstract Background In North Karelia, Finland an integration of all levels of health and social services was carried out in 2017. One of the usual targets in the service integration is to increase the performance of the service system especially in the care of patients with high use of services. The aim of this study was to assess the impact of the performed integration on the use of health services among patients with alcohol use disorders (AUD). Methods Data on all health care contacts of patients with AUD (n = 4344) covering both primary and specialized care was obtained from the electronic patient records for years 2016 to 2020. Patients having AUD were identified using AUD related ICD-10 diagnosis codes that were either set permanent for the patients or recorded at health care contacts. Information on the type of the contact (appointments and remote contacts), reason of contacts (ICD-10 code) and the professional providing the service (physician, nurse or other health professional) was collected. Results The proportion of patients with any yearly contact to health services was about 90% and did not change after the integration. The proportion of those having alcohol related contacts declined in the whole patient population, but not among the cohort having AUD related diagnosis already in 2016. Appointments decreased and remote contacts increased, but this was not associated with the year of the integration. Especially remote contacts to nurses in outpatient services increased remarkably during the two last years of the study. Conclusions Integration had very little effect on service use of AUD patients. It seemed that the overall trend with increasing remote contacts and decreasing appointments in the health services explain the observed changes. The decline of alcohol related contacts in the whole patient cohort can be explained by the identification of patients with less complicated and advanced diseases as the recording of diagnosis codes has improved. Key messages • Organizational integration of health and social services had very little impact on the service use of patients with alcohol use disorders. • There is a need of better functional integration.
