Parallel use of primary and secondary healthcare by frequent attenders in occupational health and their work disability: a longitudinal study in Finland

Abstract

ObjectivesTo investigate occupational health frequent attenders’ (FAs) use of other healthcare sector services and whether parallel use affects their likelihood to receive a disability pension.DesignLongitudinal study combining routine medical record data with register data.SettingPrimary care in Finland is provided through three parallel healthcare sectors, all available to the working population. Additionally, patients can be referred to secondary care. This study combines medical record data from a nationwide occupational healthcare provider, with healthcare attendance data from private care and from public primary and secondary care attendance, sociodemographic data and disability pension decisions.ParticipantsPatients between 18 and 68 years of age who used occupational health primary care at least once during the study years 2014–2016 were included. The total study population was 59 650 patients. They were divided into three groups (occasional and persistent FAs and non-FAs) for analysis.Primary and secondary outcome measuresThe primary outcome was FAs parallel use of private care and public primary and secondary care. The secondary outcome was work disability pension granted to FAs who used several healthcare sectors.ResultsBoth FA groups were more likely to use other healthcare service sectors more than non-FAs did. Persistent FAs were likely to use public secondary care services in particular (OR 4.31 95% CI 3.46 to 5.36). FAs using all healthcare sectors were also more likely to receive a disability pension than those FAs using only occupational health services (OR 4.53 (95% CI 1.54 to 13.34). This association was strengthened by attendance in public secondary care.ConclusionsFAs using several healthcare sectors in parallel have an increased likelihood to receive a disability pension. There is need for care coordination to ensure adequate measures for work ability support.
