Common mental disorders and musculoskeletal pain are the most frequent causes for sick leave. Despite frequent appearance,, the sick listing process is often perceived as uncertain and unclear, both among sick listed patients and health care professionals. In addition, the follow-up of patients on sick leave is sometimes lacking, leading to protracted processes and suffering for the patients. In three healthcare regions in the Southeast of Sweden, a structured framework regarding the sick listing and rehabilitation process has been developed in close collaboration between researchers and clinicians: STructured Assessment of Rehabilitation and Sick listing in primary care (henceforth referred to as STARS), to meet the needs among patients and professionals within health care, as well as to meet the statutory demands regarding coordination efforts for sick-listed patients. The comprehensive design of this study includes qualitative as well as quantitative studies, with the aim to evaluate the effects of STARS at patient, staff, and organization levels.~In a controlled pragmatic multicenter primary care study, nine centers (three from each region) working according to STARS will be compared with control centers with care as usual. The STARS framework has seven detailed method supports for health care professionals, each to be applied at different times during the first 90 days of the patients´ sick listing. Potential study participants are a) patients aged 18-65 that are sick listed due to common mental disorders, musculoskeletal pain or residual symptoms from Covid-19 and; b) medical staff involved in the sick listing- and rehabilitation process. Data will be collected through focus group interviews (health care professionals), individual interviews (patients), questionnaires (patients and health care professionals) as well as national registries regarding length and extent of sick listing. Primary outcome measures are length and extent of sick listing up until 90 days (quantitative) and the medical staffs´ experiences and perceptions regarding following the guidelines of the STARS framework (i.e. both qualitative and quantitative data). Secondary outcome measures at the included STARS centers are i) the patients' experiences regarding their sick listing process, ii) the medical staffs´ experiences of their organizational work environment , iii) causes for sick listing >90 days, and iv) health economic studies to investigate the cost-effectiveness of STARS.
In a controlled pragmatic multicenter primary care study, nine centers (three from each region) working according to a newly constructed structured framework for assessment of rehabilitation and sicklisting (STARS) will be investigated. Nine intervention centers working according to STARS will be compared to matched control centers not working according to STARS. The design of this study includes qualitative as well as quantitative measures, with the aim to evaluate the effects of STARS at patient, staff, and organization levels.
