Background: Inflammatory bowel diseases (IBDs) are incurable diseases that require lifelong access to health services. Accumulating evidence of inequalities in health care access, experience, and outcomes for individuals with IBD is apparent. This review aimed to describe the inequalities in healthcare access, experiences, and outcomes of care for adults with IBD, to identify research gaps, and to identify future research priorities in this area.
Methods: A scoping review was conducted to retrieve quantitative, qualitative, and mixed methods evidence from 3 databases (EMBASE, Medline, and CINAHL) published between January 1, 2000, and September 27, 2023.
Results: Fifty-one studies met the criteria for inclusion. The majority (42 of 51) focused on IBD health outcomes, followed by healthcare access (24 of 51). Significantly fewer investigated patient experiences of IBD healthcare (8 of 51). Most available studies reported on race/ethnic disparities of healthcare (33 of 51), followed by inequalities driven by socioeconomic differences (12 of 51), rurality (7 of 51), gender and sex (3 of 51), age (2 of 51), culture (2 of 51), literacy (1 of 51), and sexuality (1 of 51). Inflammatory bowel disease patients from Black, Asian, and Hispanic ethnic groups had significantly poorer health outcomes. A lack of research was found in the sexual and gender minority community (1 of 51). No research was found to investigate inequalities in IBD patients with learning disabilities or autism.
Conclusions: Further research, particularly utilizing qualitative methods, is needed to understand health experiences of underserved patient populations with IBD. Cultural humility in IBD care is required to better serve individuals with IBD of Black and Asian race/ethnicity. The lack of research amongst sexual and gender minority groups with IBD, and with learning disabilities, poses a risk of creating inequalities within inequalities.
Keywords: health inequalities; inflammatory bowel disease; scoping review.
Inequalities in inflammatory bowel disease healthcare access, experiences, and outcomes exist. However, it is unclear what populations and social determinants of health have been investigated in this area. This review synthesizes empirical evidence across a range of inequalities in IBD healthcare.
