A 6.75-year follow-up study in municipal eldercare workers
OBJECTIVES: The public health care sector is challenged by high sick leave rates among home-care personnel. This group also has a high probability of being granted a disability pension. We studied whether a workplace-registered frequent short-term sick leave spell pattern was an early indicator of future disability pension or future long-term sick leave among eldercare workers. METHOD: 2774 employees' sick leave days were categorised: 0-2 and 3-17 short (1-7 days) spells, 2-13 mixed short and long (8+ days) spells, and long spells only. Disability pension and long-term sick leave were subsequently identified in a National register. The cumulative incidence proportion as a function of follow-up weeks was estimated using the Kaplan-Meier curve. The relative cumulative incidence (RR) of experiencing one of these events within 352 weeks was analysed in a generalised linear regression model using the pseudo values method adjusted for age, occupation and unfavourable work factors. RESULTS: A frequent short-term and a mixed sick leave pattern increased the RR of being granted a disability pension; the RR was 2.08 (95% CI: 1.00-4.35) and 2.61 (95% CI: 1.33-5.12). Inversely, the long-term sick leave pattern was not associated with a significantly increased RR compared with a non-frequent short-term pattern. The risk of long-term sick leave was significantly increased (1.35-1.64 (95% CI: 1.12-2.03) for all sick leave patterns beyond 0-2 short spells. CONCLUSIONS: Sick leave length was a better indicator of future workability than spell frequency. Preventive actions should target employees engaged in home-care having sick leave spells exceeding seven days, irrespective of spell frequency.
