We evaluated the associations between cumulative doses of OGC and potential OGC-related AE, and quantified the associated healthcare expenditures. Methods Using the MarketScan databases, patients ≥ 18 years old who have RA with continuous enrollment from January 1 to December 31, 2012 (baseline), and from January 1 to December 31, 2013 (evaluation period), were identified. Cumulative OGC dose was measured using prescription claims during the baseline period. Potential OGC-related AE (osteoporosis, fracture, aseptic necrosis of the bone, type 2 diabetes, ulcer/gastrointestinal bleeding, cataract, hospitalization for opportunistic infection, myocardial infarction, or stroke) and AE-related expenditures (2013 US$) were gathered during the evaluation period. Multivariable regression models were fitted to estimate OR of AE and incremental costs for patients with AE. Results There were 84,357 patients analyzed, of whom 48% used OGC during the baseline period and 26% had an AE during the evaluation period. A cumulative OGC dose > 1800 mg was associated with an increased risk of any AE compared with no OGC exposure (OR 1.19, 99.65% CI 1.09–1.30). Incremental costs per patient with any AE were significantly greater for cumulative OGC dose > 1800 mg compared with no OGC exposure (incremental cost = $3528, 99.65% CI $2402–$4793). Conclusion Chronic exposure to low to medium doses of OGC was associated with significantly increased risk of potential OGC-related AE in patients with RA, and greater cumulative OGC dose was associated with substantially higher AE-related healthcare expenditures among patients with AE.
