“…A widespread skepticism prevails regarding the validity of diagnostic coding in medical claims, but previous epidemiological studies conducted with the LHID have revealed results consistent with population-based surveys for several conditions. (38) Furthermore, to maximize diagnostic coding accuracy in medical claims, the NHI has extensive and systemic qualityassurance processes including routine crosschecking of chart reviews by clinical specialists. Because cardiovascular events such as myocardial infarction and stroke are critical illnesses causing severe disability, almost all patients need medical treatments.…”

Osteoporotic fractures are associated with increased mortality risk. However, little data are available on the risk of acute myocardial infarction (AMI) after hip fracture. Therefore, we investigated whether hip fracture increased the risk of AMI in a large, nationwide cohort study. We obtained data from 8758 patients diagnosed with hip fracture from 2000 to 2009 and from 4 matched controls for each patient from the Longitudinal Health Insurance Database (LHID 2000), Taiwan. Controls were matched for age, sex, comorbid disorders, and enrollment date. All subjects were followed up from the date of enrollment until AMI, death, or the end of data collection (2009). Cox's regression model adjusted for age, sex, comorbid disorders, and medication was used to assess independent factors determining the risk of development of AMI. As expected, despite the matching, the hip fracture patients had more risk factors for AMI at baseline. A total of 8758 subjects with hip fractures and 35,032 controls were identified. Among these patients, 1183 (257 hip fracture patients and 926 controls) developed AMI during the median 3.2-year (interquartile range 1.4 to 5.8 years) follow-up period. Patients with hip fractures had a higher incidence of AMI occurrence when compared with controls (8.7/1000 person-years versus 6.82/1000 person-years). Multivariate analysis adjusted for baseline covariates indicated that hip fracture was associated with a greater risk for AMI development (hazard ratio [HR] ¼ 1.29; 95% confidence interval [CI] 1.12-1.48; p < 0.001). We conclude that hip fracture is independently associated with a higher risk of subsequent AMI. ß

Background and Purpose— Stroke is a documented risk factor for hip fracture. However, no documented studies are available on the risk of stroke among patients with hip fracture. This study investigated the frequency and risk of stroke after hip fracture using a nationwide population-based study. Methods— The study cohort included 2101 patients hospitalized with a principal diagnosis of hip fracture from 2001 to 2004. The comparison cohort consisted of 6303 randomly selected subjects matched on sex, age, and year of index healthcare use as controls. We tracked patients for a 1-year period from their index healthcare encounter to identify those who had a stroke. Stratified Cox proportional hazard regression was performed to evaluate the association of hip fracture with subsequent stroke during 1-year follow-up. Results— Of a total of 8404 patients, 86 (4.1%) from the study group and 170 (2.7%) from the comparison group had strokes during the follow-up period ( P <0.001). The stratified Cox proportional analysis shows that the 1-year crude hazard of stroke among patients with hip fracture was 1.55 times (95% CI, 1.19 to 2.03; P =0.001) that of the comparison group. Furthermore, after adjusting for the major cardiovascular risk factors, the increased stroke risk of patients with hip fracture persisted at about the same level as in the unadjusted analysis (hazard ratio, 1.53; 95% CI, 1.17 to 2.01; P =0.002). Conclusion— Hip fracture is associated with increased risk of stroke in the next year.
