Voice-supported Electronic Health Record for Temporomandibular Joint Disorders

OBJECTIVES To identify support of structured data entry for an electronic health record application in temporomandibular joint disorders. METHODS The methods of structuring information in dentistry are described and the interactive DentCross component is introduced. A system of structured voice-supported data entry in electronic health record on several real cases in the field of dentistry is performed. The connection of this component to the MUDRLite electronic health record is described. RESULTS The use of DentVoice, an application which consists of the electronic health record MUDRLite and the voice-controlled interactive component DentCross, to collect dental information required by temporomandibular joint disorders is shown. CONCLUSIONS The DentVoice application with the DentCross component showed the practical ability of the temporomandibular joint disorder treatment support.

Flexible information storage in MUDRII EHR

An important research task of the EuroMISE Centre is the applied research in the field of electronic health record (EHR) design including electronic medical guidelines and intelligent systems for data mining and decision support. The research in this field was inspired by several European projects. We have proposed a mathematical meta-description of a flexible information storage model based on the experience gathered in cooperation in those projects. In this model, we use two basic structures called a knowledge base and data files. We describe those two structures using the graph theory concepts. Furthermore, we use logical formulas to express conditions that should be valid. Additionally, we present a description of a global system architecture of a 3-tier EHR application with interfaces based on the latest technologies; predominately on Web Services, SOAP, XML, HTTP, CORBA, etc. According to our experience and test results gained from the MUDR EHR usage, we describe an open universal solution, which can be applied as the EHR kernel of hospital information systems. To realize this approach in a daily practice for health professionals we have started a co-operative project with clinical information systems developers. Within that project we are developing a new system for continual shared health care.

On Direct Comparing of Medical Guidelines with Electronic Health Record

Electronic Health Record (EHR) systems are now being developed in many places. The EuroMISE Center has developed a system of the Multimedia Distributed Electronic Health Record (MUDR) that provides universal structure for collecting data and multimedia objects. Moreover, a method to compare data items on the input of EHR system with medical guidelines has been developed. Therefore it is possible to reveal if the input data item, that represents patient diagnosis or proposed patient treatment, contradicts with medical guidelines or not. The method on direct comparing of medical guidelines with EHR has been tested in hospital information system settings and in settings of the remote GP office.

Enhanced care of hypertensive patients using the Internet

Background : Medical guidelines provide recommendations that ought to help physicians in medical decision-making under different circumstances. To develop electronic medical guidelines and to make them available for physicians using the Internet can further enhance the quality and efficiency of health care, especially with the simultaneous use of electronic health records. Objectives : This study aims to outline the needs for web-based systems that support the use of medical guidelines in practice; and to focus on the development of web-based electronic medical guidelines for treatment of arterial hypertension. Methods : The importance of electronic health record in cardiology for data acquisition, data storage and data mining is considered. The anonymized database of approximately 1800 hypertensive patients has been created to compare medical practice with guidelines and discover features of diseases that can help with their management. Using this database we evaluated several web-based electronic guidelines systems. Results : The 1999 WHO/ISH Guidelines for the Management of Hypertension were formalized and interpreted using the Guide-X methodology, using the Apollo system and web-based electronic guidelines. The web-based electronic guidelines were tested on the smaller anonymous recent data set of 840 hypertensive patients. Conclusions : An easy transfer of knowledge from medical guidelines to structured electronic guidelines opens new possibilities for easy reusability of medical knowledge by general practitioners and clinicians.
