BACKGROUND: Maintenance of bone health is an important concern in patients with inflammatory bowel disease (IBD). They may frequently have impaired bone density resulting in greater incidence of fractures.
AIMS: To examine fracture-associated hospitalization costs in IBD patients from a nationwide representative sample, and to compare the risk factors for such fractures in IBD and non-IBD patients.
METHODS: We identified discharges with IBD and coexisting codes for hip, vertebral or wrist fractures (IBD-Fr) from the Nationwide Inpatient Sample and compared them with IBD hospitalizations without codes for these fractures. A second analysis was performed using 2008 inpatient data from the Wisconsin Hospital Association (WHA) comparing characteristics of patients with IBD-Fr and non-IBD controls hospitalized for similar fractures.
RESULTS: There were 1,653 discharges in the IBD-Fr group accounting for 10,461 days of hospital stay and US $46 million in total hospitalization charges. On multivariate analysis, age>65 years [odds ratio (OR) 28.8, 95% confidence interval (CI) 12.3-67.6] and female sex (OR 1.3, 95%CI 1.0-1.6) were associated with higher odds of hospitalization associated with fractures. We found no differences in age, gender, or race among IBD-Fr and non-IBD fracture controls. However, IBD-fractures were twice as likely to be associated with osteoporosis as non-IBD fractures (OR 2.19, 95%CI 1.10-4.33).
CONCLUSIONS: Older age, female sex, and osteoporosis were more commonly associated with hospitalization for fractures in IBD patients. Osteoporosis appears to be more common among IBD-Fr patients than non-IBD fracture controls.
