E-health and healthcare enterprise information system leveraging service-oriented architecture.

Objective: To present the successful experiences of an integrated, collaborative, distributed, large-scale enterprise healthcare information system over a wired and wireless infrastructure in National Taiwan University Hospital (NTUH). In order to smoothly and sequentially transfer from the complex relations among the old (legacy) systems to the new-generation enterprise healthcare information system, we adopted the multitier framework based on service-oriented architecture to integrate the heterogeneous systems as well as to interoperate among many other components and multiple databases. We also present mechanisms of a logical layer reusability approach and data (message) exchange flow via Health Level 7 (HL7) middleware, DICOM standard, and the Integrating the Healthcare Enterprise workflow.

Design ensemble machine learning model for breast cancer diagnosis.

In this paper, we classify the breast cancer of medical diagnostic data. Information gain has been adapted for feature selections. Neural fuzzy (NF), k-nearest neighbor (KNN), quadratic classifier (QC), each single model scheme as well as their associated, ensemble ones have been developed for classifications.

Usability evaluation of mobile medical treatment carts: another explanation by information engineers.

Healthcare services integration is a critical task as it attempts to reform the user practices. In response to the request of facilities upgrade, we perform a usability evaluation of the mobile medical treatment carts (MMTC) installed in the Emergency Medicine Department of our healthcare enterprise. A survey conducted in August 2006 identified that our experimental area needs some improvements to support the MMTC adoption.

An agile enterprise regulation architecture for health information security management.

Information security management for healthcare enterprises is complex as well as mission critical. Information technology requests from clinical users are of such urgency that the information office should do its best to achieve as many user requests as possible at a high service level using swift security policies. This research proposes the Agile Enterprise Regulation Architecture (AERA) of information security management for healthcare enterprises to implement as part of the electronic health record process.

A multi-voting enhancement for newborn screening healthcare information system.

The clinical symptoms of metabolic disorders during neonatal period are often not apparent. If not treated early, irreversible damages such as mental retardation may occur, even death. Therefore, practicing newborn screening is essential, imperative to prevent neonatal from these damages.

Application of portable CDA for secure clinical-document exchange.

Health Level Seven (HL7) organization published the Clinical Document Architecture (CDA) for exchanging documents among heterogeneous systems and improving medical quality based on the design method in CDA. In practice, although the HL7 organization tried to make medical messages exchangeable, it is still hard to exchange medical messages. There are many issues when two hospitals want to exchange clinical documents, such as patient privacy, network security, budget, and the strategies of the hospital.

Newborn screening healthcare information system based on service-oriented architecture.

In this paper, we established a newborn screening system under the HL7/Web Services frameworks. We rebuilt the NTUH Newborn Screening Laboratory's original standalone architecture, having various heterogeneous systems operating individually, and restructured it into a Service-Oriented Architecture (SOA), distributed platform for further integrity and enhancements of sample collections, testing, diagnoses, evaluations, treatments or follow-up services, screening database management, as well as collaboration, communication among hospitals; decision supports and improving screening accuracy over the Taiwan neonatal systems are also addressed. In addition, the new system not only integrates the newborn screening procedures among phlebotomy clinics, referral hospitals, as well as the newborn screening center in Taiwan, but also introduces new models of screening procedures for the associated, medical practitioners.

Design and implementation of web-based discharge summary note based on service-oriented architecture.

Discharge summary note is one of the essential clinical data in medical records, and it concisely capsules a patient's status during hospitalization. In the article, we adopt web-based architecture in developing a new discharge summary system for the Healthcare Information System of National Taiwan University Hospital, to improve the traditional client/sever architecture. The article elaborates the design approaches and implementation illustrations in detail, including patients' summary query and searching, model and phrase quoted, summary check list, major editing blocks as well as other functionalities.

Design and implementation of web-based mobile electronic medication administration record.

Patients' safety is the most essential, critical issue, however, errors can hardly prevent, especially for human faults. In order to reduce the errors caused by human, we construct Electronic Health Records (EHR) in the Health Information System (HIS) to facilitate patients' safety and to improve the quality of medical care. During the medical care processing, all the tasks are based upon physicians' orders.

A newborn screening system based on service-oriented architecture embedded support vector machine.

The clinical symptoms of metabolic disorders are rarely apparent during the neonatal period, and if they are not treated earlier, irreversible damages, such as mental retardation or even death, may occur. Therefore, the practice of newborn screening is essential to prevent permanent disabilities in newborns. In the paper, we design, implement a newborn screening system using Support Vector Machine (SVM) classifications.
