Inflammatory bowel diseases and work disability: a systematic review of predictive factors.

OBJECTIVE

Inflammatory bowel diseases (IBD), including Crohn's disease (CD) and Ulcerative Colitis (UC), are chronic, relapsing intestinal disorders that may severely compromise patients' labour force participation. In this context, the present review aims to provide an overview on possible IBD pathological, socio-demographic, and treatment-related factors predictive for work disability with the purpose to provide guidance for a successful clinical and occupational management.

MATERIALS AND METHODS

A systematic review of PubMed, Scopus, and ISI Web of Science databases was performed to retrieve all the studies addressing IBD-related predictors for work disability.

RESULTS

Several factors have been suggested to predict work disability in the 15 revised investigations, although with not homogeneous results. Having CD was reported as a significantly better predictor for permanent work disability compared to UC, maybe in relation to the generally more serious disease course. Activity and severity of IBD, also indicated by the need for surgical treatment and comorbidities, was related to a significantly greater risk for work disability, although the exact role of other variables, i.e., specific symptoms, disease pattern and inflammatory parameters are still unclear. Among demographic factors, a significant predictive role has been suggested for female gender.

CONCLUSIONS

Further research seems necessary to confirm the role of IBD related factors on work disability, and on other parameters of work impairment, i.e., absenteeism, presenteeism, activity and productivity loss. Additionally, work disability should be evaluated in relation to specific occupational risk factors. Overall, this may require a multidisciplinary approach aimed to achieve an adequate IBD clinical evaluation and management, an improvement of patients' psychosocial and professional well-being, while appropriately assessing and managing risks in the workplace.
