One of the most potentially useful external sources of(More)
BACKGROUND Usually patients receive healthcare services from multiple hospitals, and consequently their healthcare data are dispersed over many facilities' paper and electronic-based record systems. Therefore, many countries have encouraged the research on data interoperability, access, and patient authorization. This study is an important part of a(More)
The Taiwan government has been promoting Electronic Health Records (EHRs) to primary care physicians. How to extend EHRs adoption rate by measuring physicians' perspective of importance and performance of EHRs has become one of the critical issues for healthcare organizations. We conducted a comprehensive survey in 2010 in which a total of 1034(More)
BACKGROUND Bilateral total knee arthroplasty (TKA) is required for many patients. There are few studies comparing the overall costs of staged and simultaneous bilateral TKA. METHODS The Taiwan National Health Insurance Research Database (NHIRD) was searched, and the total medical costs of 452 patients who received simultaneous bilateral TKAs were compared(More)
OBJECTIVE Despite of emerging evidence that electronic health records (EHRs) can improve the clinical quality, enhances patient safety and efficiency. Most physicians in primary health care clinics in the Taiwan do not currently adopt EHR at their clinic practices. We aim to measure the relationship between usage intention and adoption behavior.
