Popis: The study was to investigate the outcomes of rheumatoid arthritis (RA) patients with hip fractures with a large-scale, population-based, nationwide, case-cohort study using the Taiwan National Health Insurance database. The group has hip fractures at a younger age, higher complication, and mortality rate, which indicate that early intervention is necessary. This study seeks to evaluate the incidence, mortality, and complication rates in RA patients with hip fractures, using a nationwide database. Data were collected from the National Health Insurance Research Database of Taiwan. The study group included 117,129 patients with hip fractures diagnosed from January 2004 to December 2010. Matching based on the propensity of RA patients was used. In total, 1,088 hip fractures were reported among patients with RA. Patients with hip fractures were divided into two groups: those without RA (controls) and those with RA (RA group). The incidence of hip fracture and mortality and complication rates after the hip fracture were then compared between the two groups. RA patients had a significantly higher incidence of hip fracture (3,260/100,000 person-years) compared with the general population (72/100,000 person-years). Hip fractures occurred significantly earlier among RA patients (70.6 ± 5.3 years) compared with the control group (76.1 ± 6.2 years). Cumulative mortality rates at 6-month and 1-year follow-up were significantly higher among patients in the RA group (9.47 and 18.47 %) compared to the controls (8.47 and 13.62 %) and among RA patients without hip fractures (3.24 and 6.16 %). There was a significantly higher incidence of osteomyelitis after hip fracture among the RA group than among the body mass index-, comorbidity-, age-, and sex-matched patients in the control group. Compared to patients without RA, those with RA have a higher incidence of hip fractures at a relatively younger age and with higher complication and mortality rates. Steroid and disease-modifying anti-rheumatic drugs, the most common medicine in Taiwanese RA patients, might contribute to the high incidence of fracture and post-op infection. Appropriate early intervention to prevent hip fractures in RA patients is a critical issue in rheumatology care.
