Sickness absence remains a major challenge globally. Primary care physicians often find it challenging to deny patients' requests for sick leaves, making the gatekeeping role uneasy among doctors.

Twenty-one PCPs participated in this non-randomized intervention study. The educational intervention consisted of an interactive presentation, a 20-minute video screening, and 3 text message reminders. The average number for sickness certificates (SCs), sickness absence rate per patient, and causes for sickness absence spells were measured one year before and one year after the intervention.

The average number of SC one year before and after the intervention was 0.44 and 0.47, respectively. The sickness absence rate was 0.63% one year before and 0.75% one year after the intervention with no statistical significance. The mean number of sickness absence days did not significantly change. Causes for sickness absence spells significantly increased for diarrhea and back pain but decreased for upper respiratory infections with no statistical significance.

Implementation of a multifaceted intervention to train PCPs on the process of sickness certification did not affect the sickness absence rate. Further research is needed to assess the knowledge and understanding of physicians' sickness certification process and the underlying factors that govern it to better develop tailored and effective interventions.
