Summary: The association between Parkinson’s disease and fracture was not completely understood. This nationwide study investigated increased risk of fracture in patients with Parkinson’s disease. In the nested cohort study, Parkinson’s disease was associated with pneumonia, septicemia, stroke, urinary tract infection, and mortality after fracture admission. Introduction: Falls are a common complication in people with Parkinson’s disease (PD). This study evaluated fracture risk and post-fracture outcomes in patients with PD. Methods: We identified 1,423 adults aged 40 years and older newly diagnosed with PD using the Taiwan National Health Insurance Research Database from 2000 to 2003. Comparison cohort consisted of 5,692 adults without PD randomly selected from the same dataset, frequency matched in age and sex. Followed-up events of fracture from January 1, 2000, until December 31, 2008, were ascertained from medical claims. Adjusted hazard ratios (HR) and 95 % confidence interval (CI) of fracture associated with PD were evaluated. Another nested cohort study of 397,766 hospitalized fracture patients analyzed for adjusted odds ratios (ORs) and 95 % CIs of adverse events after fracture among patients with and without PD between 2004 and 2010. Results: The incidences of fracture for people with and without PD were 39.5 and 23.9 per 1,000 person-years, respectively (p <0.0001). Compared with control, the adjusted HR of fracture was 2.25 (95 % CI 1.97–2.58) for PD patients. Previous PD was associated with risks of pneumonia (OR 1.44, 95 % CI 1.36–1.52), septicemia (OR 1.41, 95 % CI 1.33–1.49), stroke (OR 1.40, 95 % CI 1.32–1.50), urinary tract infection (OR 1.53, 95 % CI 1.46–1.61), and mortality (OR 1.25, 95 % CI 1.15–1.35) after fracture. Conclusions: PD was associated with higher risk of fracture. Patients with PD had more complications and mortality after fracture. Fracture prevention and attention to post-fracture adverse events are needed for this susceptible population.
