Background: From the viewpoint of prehospital emergency medicine, a greater proportion of pelvic fractures not of a life-threatening status but combined with other injuries need more comprehensive recognition.
Methods: A 12-year nationwide health database of inpatients was reviewed. All cases diagnosed as pelvic fractures were enrolled.
Background: In Taiwan, the policy of catastrophic illness certificates has benefited some populations with specific diseases, but its effect on the use of medical services and the sequence of public health has not been examined. As a pilot of a series of studies, focused on emergency department (ED) visits, the present study aimed to compare medical utilization and various diagnostic categories at EDs between the elderly with an identified catastrophic illness and the elderly without.
Methods: A cross-sectional study, based on a large-sample nationwide database (one million of the population, randomly sampled from Taiwan's National Health Insurance Research Database (NHIRD)), was performed in Taiwan.
Background: The relationship between psychiatric disorders and musculoskeletal injuries is interesting but has not been investigated in depth.
Study Design: A retrospective cohort study, based on a large-sample nationwide database, was performed during 2000-2005 in Taiwan.
Methods: All subjects matching the inclusion criteria of psychiatric-associated ICD9-CM diagnostic codes in 2000 were selected as the inception cohort population.
Background: The epidemiology of acute orthopedic dislocations is poorly understood. A nationwide database provides a valuable resource for examining this issue in the Taiwanese population.
Methods: A 6-year retrospective cohort study of 1,000,000 randomly-sampled beneficiaries from the year 2005 was used as the original population.
Background: Almost all studies of pathologic fractures have been conducted based on patients with tumours and hospital-based data; however, in the present study, a nationwide epidemiological survey of pathologic fractures in Taiwan was performed and the medical utilization was calculated.
Methods: All claimants of Taiwan's National Health Insurance (NHI) Program in 2008 were included in the target population of this descriptive cross-sectional study. The registration and inpatient expenditure claims data by admission of all hospitalized subjects of the target population were examined and the concomitant International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis codes were evaluated and classified into seven major categories of fracture.
Background: Injury is the most common diagnostic category in the emergency unit, but no survey of epidemiological data for trauma or orthopaedic fractures has been made to date in Taiwan. A nationwide study of orthopaedic injuries is therefore necessary and would be of benefit to the Taiwanese population.
Methods: A qualified dataset, provided by a governmental authority, containing the original claims data of 1,000,000 randomly-sampled claimants from the year 2005 in Taiwan was analyzed, and a survey was made of 12 categories of orthopaedic fracture based on the ICD9-CM codes using two sets of data: inpatient data and ambulatory care data.
