The cost of saying no: general practitioners’ gatekeeping role in sickness absence certification

General practitioners (GPs) have an important gatekeeping role in the Norwegian sickness insurance system. This role includes limiting access to paid sick leave when this is not justified according to sick leave criteria. 85% of GPs in Norway operate within a fee-for-service system that incentivises short consultations and high service provision. In this qualitative study, we explore how GPs practise the gatekeeping role in sickness absence certification.
