Oncologists frequently have sickness certification (SC) consultations, however, little is known about their experiences of such tasks.

OBJECTIVE: To investigate oncologists' experiences of organisational prerequisites for SC tasks, and if lack of resources was related to experiencing SC as problematic.

METHOD: Questionnaire data from 342 oncologists in Sweden were used for descriptive statistics and to calculate odds ratios (OR) with 95% confidence intervals (CI).

RESULTS: The majority (92.2%) had SC consultations weekly; 17.8% of the oncologists experienced such consultations as problematic weekly. About a third appreciated the national guidelines for SC (34.5%) and had joint routines/policies regarding SC at their clinic (29.7%). Experiencing SC consultations as problematic was associated with stating not having enough resources for such work (OR 3.47; 95% CI 1.92-6.25). Lack of resources was associated with: experiencing lack of competence in insurance medicine (3.34; 1.92-5.82), conflicts with patients regarding SC (4.22; 1.96-9.07), finding it problematic to manage the two roles as medical expert and as the patient's treating physician (3.31; 2.04-5.34), or to assess work capacity (2.28; 1.46-3.56).

CONCLUSION: Although oncologists often had SC tasks, most did not experience them as problematic weekly. However, lack of resources for SC tasks was associated with experiencing SC as problematic.
