Purpose: Patients with Crohn’s disease have increased work loss. We aimed to describe changes in work ability in relation to pharmacological and surgical treatments.
Patients and Methods: We linked data from the Swedish National Patient Register, The Swedish Quality Register for Inflammatory Bowel Disease SWIBREG, The Prescribed Drug Register, The Longitudinal Integrated Database for Health Insurance and Labour Market Studies, and the Social Insurance Database. We identified working-age (19– 59 years) patients with incident Crohn’s disease 2006– 2013 and population comparator subjects matched by sex, birth year, region, and education level. We assessed the number of lost workdays due to sick leave and disability pension before and after treatments.
Results: Of 3956 patients (median age 34 years, 51% women), 39% were treated with aminosalicylates, 52% with immunomodulators, 22% with TNF inhibitors, and 18% with intestinal surgery during a median follow-up of 5.3 years. Most patients had no work loss during the study period (median=0 days). For all treatments, the mean number of lost workdays increased during the months before treatment initiation, peaked during the first month of treatment and decreased thereafter, and was heavily influenced by sociodemographic factors and amount of work loss before first Crohn’s disease diagnosis. The mean increase in work loss days compared to pre-therapeutic level was ∼ 3 days during the first month of treatment for all pharmacological therapies and 11 days for intestinal surgery. Three months after treatment initiation, 88% of patients treated surgically and 90– 92% of patients treated pharmacologically had the same amount of work loss as before treatment start. Median time to return to work was 2 months for all treatments.
Conclusion: In this regular clinical setting, patients treated surgically had more lost workdays than patients treated pharmacologically, but return to work was similar between all treatments.
