The Collaboration Project Sustainable Sick Leave (BS) is a part of AID ́s work on following-up the Contract for reduced sick leave and loss from working life (the IA agreement). The collaboration project is anchored in the national budget (Chapter 601, item 75 Enclosed for effective sick leave) and annual awards from AID to the Norwegian Medical Association. The contracting authority would like, with the procurement, to implement an evaluation project that shall be both directed towards mapping the effects/results of the initiatives in the collaboration project BS, at the same time as it is relevant to map and assess the efforts and activities in the cooperation project. Reporting along the way shall contribute to adjusting the measures. The procurement is related to work with following-up sick leave and particularly the interaction between the gp and patient. The collaboration project shall strengthen the GP's role in sick leave work and increase health competence of the population. The project involves implementing initiatives aimed at both general practitioners and patients. The measure includes both awareness raising and training measures aimed at their gp about their sick leave practice and measures to increase patients' awareness and understanding of sick leave. The aim is that cooperation between doctor and patient on sick leave shall be better, and thus contribute to fewer, shorter and better adapted sick leave, including increased use of graded sick leave. There is a need for knowledge that maps the activities in the collaboration project, on the initiatives will be assessed as relevant in the consultation with the sick leavers, whether the measures have an effect on their gp's sick leave practice and if their GP finds that cooperation with registered sick leave, employer, the Norwegian Labour and Welfare Administration has improved and their role and responsibilities in follow-up sick leave has become clearer. There is also a need for knowledge on the collaboration project has contributed to reduced sick leave. The collaboration project is a development project where feedback can be given during the process (evaluation of the process).
