In this article, a Website for medical healthcare system was designing and developing. It consists of two major sides: client- server side (front end side and back end side). The client-side is everything involved with what the user sees, it has been designed a web using HTML, CSS and JavaScript languages. The server-side is mainly how the site doing modifications and updates which indicates to the entire user can't see everything in the browser such as servers and databases. The web has been implemented and developed using ASP MVC5 and C# programming language. SQL Server languages used for the database part and it make simple ease of use for patients to their health registrations. Consequently, it has simple and straight accessibility through a group of physicians for patient records. The article interested with auspices to the patient appointments combination, billing, timetable, physical, date, and information of medication in single overall system. The results of website designed provide accessibility with easy manner of pertinent information to the management organizations for instance the Medicaid and Medicare.

Mehrwertanwendungen der elektronischen Gesundheitskarte sollen Patientenorientierung sowie Qualitäts- und Effizienzsteigerungen im Gesundheitswesen ermöglichen. Die Dienste der Gesundheitstelematik, bei der die elektronische Gesundheitskarte nur eine Teilkomponente ist, können dabei beliebig eingebunden werden, etwa um Sicherheitsstandards und Interoperabilität zu gewährleisten. Der gestaltungsorientierte Beitrag präsentiert die Entwicklung und Evaluierung einer Softwarearchitektur für Mehrwertanwendungen. Um die Akzeptanz der Nutzer zu steigern, wurden die Architekturanforderungen direkt bei den Leistungserbringern erhoben. Die Architektur wird anhand des elektronischen Überweisungsmanagements illustriert und evaluiert. Es werden typische Funktionseinheiten von medizinischen Abläufen in sieben Schichten abstrahiert. Die Instanziierung zeigt eine strukturierte Anwendung mit übergreifenden Sicherheitsstandards, die Interoperabilität zwischen heterogenen Bestandssystemen und eine übergreifende Steuerung durch Ärzteverbünde ermöglicht. Die Architektur bietet erstmalig im deutschen Gesundheitswesen die Möglichkeit, eine Vielzahl von Mehrwertanwendungen systematisch, einfach, sicher und zuverlässig zu spezifizieren und zu entwickeln, um sie über die Telematikinfrastruktur zur Verfügung zu stellen.

Value-added applications of the German healthcare telematics aim at patient orientation as well as quality and efficiency improvements in the healthcare sector. Telematics services can be utilized in many ways, e.g., to guarantee security standards and interoperability. The electronic health card is merely one example. The design science oriented article presents the development and evaluation of a soft- ware architecture for value-added applications. In order to achieve better user acceptance, the architectural requirements were derived directly from the caregivers. The architecture is illustrated and evaluated by the example of electronic referral management. Typical functional units of medical processes are modeled in seven layers. The instantiation shows a structured application with high security standards which enables interoperability between heterogeneous existing systems and extensive control by physicians’ cooperatives. The architecture offers, for the first time in German healthcare, the opportunity to safely and reliably specify and develop a variety of value-added applications which can be provided via the telematics infrastructure.
... Therefore, hospitals need to integrate a large number of heterogeneous distributed healthcare information systems to provide nurses with useful patient care information. 44 In conclusion, in adopting HISs, health organizations must ensure the quality of information, as it is closely related to the perception of nurses regarding the usefulness and ease of use. To encourage individuals to adopt and use the HISs, managers must place a greater emphasis on facilitating the conditions, training, and the usefulness of the HISs. ...

This study proposed an evaluation model, derived from the Technology Acceptance Model and Information System Success Model, to explore factors influencing the acceptance of hospital information systems by nurses. Although many healthcare institutions have applied hospital information systems, relatively few studies have investigated the perceptions of nurses regarding the usefulness, ease of use, or acceptance of these systems. This study recruited the nursing staff of a regional hospital in Taiwan. A total of 297 questionnaires were sent, and 277 were returned, for a response rate of 93.3%. The results indicated that system quality, information quality, and service quality were positively correlated with the perceived ease of use (R=0.69) and perceived usefulness (R=0.72). Information quality has the greatest influence on perceived usefulness (γ3=0.57, P<.001) and ease of use (γ4=0.61, P<.001). Perceived usefulness and ease of use have a significant influence on system acceptance (R=0.75). Perceived usefulness (β1=0.61, P<.001) has a significant influence on system acceptance. These findings indicated that nursing care requires high-quality healthcare information to support the daily activities of nursing professionals. The results of this study also provide a valuable reference for hospital administrators in developing hospital information systems.

Large-scale distributed systems, such as e-healthcare systems, are difficult to develop due to their complex and decentralized nature. The service oriented architecture facilitates the development of such systems by supporting modular design, application integration and interoperation, and software reuse. With open standards, such as XML, SOAP, WSDL and UDDI, the service oriented architecture supports interoperability between services operating on different platforms and between applications implemented in different programming languages. In this paper we describe a distributed e-healthcare system that uses the service oriented architecture as a basis for designing, implementing, deploying, invoking and managing healthcare services. The e-healthcare system that we have developed provides support for physicians, nurses, pharmacists and other healthcare professionals, as well as for patients and medical devices used to monitor patients. Multi-media input and output, with text, images and speech, make the system more user friendly than existing e-healthcare systems.

Ubiquitous computing techniques are ideal tools to bring new solutions to environments which are otherwise quite resistant to rapid change. In this paper we present techniques to carry out experiments in the very heterogeneous environment of a hospital's decision making conference, the "tumour board". Introducing the concept of surface interaction we demonstrate how information from various sources such as X-ray film, slide presentations and projections of CT scans together with oral comments and typed notes can be captured and made available for surgeons' use in the operating theatre, without interfering with the "old" way of holding the meeting and without putting any extra burden on the hospital staff. Ubiquitäre Informationstechnologien sind geeignete Werkzeuge, um innovative Lösungen in Umgebungen einzuführen, die in der Regel eher konservativ sind und in denen Neuerungen sonst häufig auf Widerstand stoßen. In diesem Beitrag stellen die Autoren einen Ansatz vor, der es ermöglicht, die Wirkung neuer Technologien in der heterogenen Umgebung eines Krankenhauses zu untersuchen. Hierzu wird eine typische Konferenzsituation, das so genannte "Tumor-Board", in der das medizinische Personal über Patienten spricht und Entscheidungen über Therapien und Vorgehensweisen fällt, betrachtet. Die Autoren führen das Konzept der Interaktion mit Oberflächendaten (z. B. Videoausgaben für die Projektion oder Datenströme von der Tastatur) ein und zeigen, wie damit Daten von verschiedenen Quellen wie Röntgenfilmen, digitale Folienpräsentationen oder CT-Daten zusammen mit mündlichen Kommentaren aus der Diskussion in der Konferenz aufgezeichnet und später dem Chirurgen im OP zugänglich gemacht werden können. Der Ansatz zeichnet sich dadurch aus, dass die traditionelle Vorgehensweise bei der Entscheidungskonferenz beibehalten wird und dass durch die Aufzeichnung keine zusätzliche Arbeit für das beteiligte medizinische Personal entsteht.

... They are assured by the fact that a trusted professional can 'attend' them 24 hours a day, regardless of where they or their physician are located. Plus, instantaneous patient information in the hands of their physician can lead to swifter treatment (Tsiknakis et al., 1997). The clinical staff in local care centres would be able to obtain expert advice via e-links from clinicians in a wide range of hospital specialities – for example radiology and imaging, endoscopy, dermatology, endocrinology ophthalmology, psychiatry, minor trauma, cardiology and pathology. ...

The internet has enhanced the ability of healthcare providers successfully to manage projects spanning time zones, cultures and physical distances. The high cost of healthcare in the USA is not only affecting the healthcare industry but also placing a great burden on the competitiveness of many major US manufacturing and other businesses. The biggest challenge for both providers and payers in the healthcare industry is not about HIPAA compliance but about how to be profitable. In response to cost-reduction pressures, healthcare providers are exploring a new option of offshore healthcare delivery. This paper develops an offshore healthcare delivery model. The offshore healthcare delivery model has a vast potential to improve both patient- and system-level outcomes, especially by improving access, efficiency and continuity of care. However, these benefits are not automatic and policy decisions about the extension of the offshore healthcare delivery model must be made after careful evaluation of exactly how the offshore healthcare delivery model affects outcomes and whether these outcomes justify the associated costs. The paper also examines the various potential issues and outlines some of the challenges in implementing the model. The study is based on examining the USA healthcare delivery model and subsequent discussions with many medical practitioners in the USA and India. The study outlines the framework of the offshore healthcare model and points out critical issues and challenges that need further examination before the model is considered as clinically viable for cost-effective treatments and quality care.
