The association of inflammatory bowel disease with postoperative complications, re-admissions and emergency department visits following primary total hip arthroplasty.

Abstract

Inflammatory bowel disease (IBD) is a systemic inflammatory disorder of the gut. Few studies have evaluated whether patients with a history of IBD have worse outcomes following primary total hip arthroplasty (THA). Therefore, the purpose of this study was to evaluate whether IBD is associated with increased: (1) medical complications; (2) readmissions; and (3) emergency department (ED) visits. Using a nationwide claims database, patients with IBD undergoing primary THA were identified and matched to a comparison group according to age, sex and the Charlson Comorbidity Index. Outcomes assessed included the development of 90-day medical complications, 90-day re-admissions and 90-day ED visit rates. A <i>p-</i>value <0.0001 was considered statistically significant. Patients with IBD had a greater incidence and odds ratio of total medical complications (31.90% vs. 11.47%; OR 2.89; <i>p</i> < 0.0001) compared with matched controls. IBD patients had significantly higher incidence and odds ratio of developing acute kidney injury (5.46 vs. 1.46%; OR 3.92; <i>p</i> < 0.0001), cerebrovascular accident (1.32 vs. 0.35%; OR 3.79; <i>p</i> < 0.0001), pneumonia (4.02 vs. 1.30%; OR 3.19; <i>p</i> < 0.0001), respiratory failure (1.21 vs. 0.41%; OR 2.94; <i>p</i> < 0.0001), deep vein thrombosis (0.89% vs. 0.30%; OR 2.93; <i>p</i> < 0.0001), and other adverse events. IBD patients also had higher incidence and odds ratio of 90-day re-admissions (4.20% vs. 3.23%; OR 1.31; <i>p</i> < 0.0001) and ED visits (6.56% vs. 3.99%; OR 1.69; <i>p</i> < 0.0001). This study found that patients with IBD are at increased risk of 90-day medical complications, re-admissions, and ED visits. Due to its systemic nature, surgeons operating on these patients should be aware of the disease's extra-intestinal manifestations, and the potential postoperative risks in IBD patients. Providers should use this investigation when educating patients on potential risks of elective THA.
