Epidemiological survey of orthopedic joint dislocations based on nationwide insurance data in Taiwan, 2000-2005

BackgroundThe epidemiology of acute orthopedic dislocations is poorly understood. A nationwide database provides a valuable resource for examining this issue in the Taiwanese population.MethodsA 6-year retrospective cohort study of 1,000,000 randomly-sampled beneficiaries from the year 2005 was used as the original population. Based on the hospitalized and ambulatory data, the concomitant ICD9-CM diagnosis codes and treatment codes were evaluated and classified into 8 and 3 major categories, respectively. The cases matching both inclusive criteria of dislocation-related diagnosis codes and treatment codes were defined as incident cases.ResultsDuring 2000-2005, the estimated annual incidence (per 100,000 population) of total orthopedic dislocations in Taiwan was 42.1 (95%CI: 38.1-46.1). The major cause of these orthopedic dislocations was traffic accidents (57.4%), followed by accident falls (27.5%). The annual incidence dislocation by location was shoulder, 15.3; elbow, 7.7; wrist, 3.5; finger, 4.6; hip, 5.2; knee, 1.4; ankle, 2.0; and foot, 2.4. Approximately 16% of shoulder dislocations occurred with other concomitant fractures, compared with 17%, 53%, 16%, 76% and 52%, respectively, of dislocated elbow, wrist, hip, knee, and ankle cases. Including both simple and complex dislocated cases, the mean medical cost was US

The most common complex fracture-dislocation was of the knee, followed by the wrist and the ankle. Those usually needed a treatment combined with open reduction of fractures and resulted in a higher direct medical expenditure.

Using Big Data to Develop the Epidemiology of Orthopedic Trauma

AIMS The purpose of this study was to perform a cross-sectional population-based study of hospitalised cases due to acute spinal trauma in Taiwan, based on information from the nationwide National Health Insurance (NHI) database. METHODS To calculate the annual incidence of hospitalised acute spinal trauma, evaluate the distribution of neurological injury and its surgical intervention, and analyse the use of medical resources and related factors in Taiwan, the entire inpatient datasets were selected between 2000 and 2003 for use in the present study. RESULTS There were 13,371, 13,800, 13,728 and 13,585 cases identified in 2000, 2001, 2002 and 2003, respectively, the average incidence of hospitalised acute spinal trauma in Taiwan was 61.61/100,000, and it was similar in both genders (rate ratio of male to female: 0.99). There was a significant trend of increased incidence with increasing age in both genders, particularly after the age of 60. The decreasing incidence rate ratios of neurological deficit to neurological intactness are 0.75, 0.58, 0.45, 0.26 and 0.16 in the age strata of 0-19, 20-39, 40-59, 60-79 and 80 or more years, respectively. In general, the operation rate is only 17.3% of all acute spinal injury cases, but it would be up to a significant 29.5% if the patients had spinal fractures with neurological insufficiency. There is an obvious decreasing trend of operation rate in spinal bony trauma with age, but a reverse trend is noted in the group with spinal nerve injury without spinal fracture. Finally, the enrolled subjects of acute spinal injuries spent

The above two variables of hospitalised medical utilisation are significantly different when considering gender, neurological status, and surgical intervention or not. Noticeably, if operative treatment for acute spinal injury is necessary, the LOS would increase by two times and the medical cost by six times. CONCLUSION In Taiwan, the annual incidence of hospitalised acute spinal injuries was higher but the direct cost was much lower. The characterisation of gender ratio, neurological condition, and surgical performance had been significantly effected by age.
