Health Level Seven (HL7) and Digital Imaging and Communications in Medicine (DICOM) standards are strongly influencing Electronic Health Records (EHRs) standardization. In this chapter, we present a web-based application, TeleOftalWeb 3.2, to store and exchange EHRs in ophthalmology by using HL7 Clinical Document Architecture (CDA) and DICOM standards. EHRs are stored in the native Extensible Markup Language (XML) database, dbXML 2.0. Application architecture is triple-layered with two database servers (MySQL 5.0 and dbXML) and one application server (Tomcat 5.5.9). Physicians can access and retrieve patient medical information and all types of medical images through web browsers. For security, all data transmissions are carried over encrypted Internet connections such as the Secure Sockets Layer (SSL) and Hypertext Transfer Protocol over SSL (HTTPS). The application verifies the standards related to privacy and confidentiality. The application is being tested by physicians from the University Institute of Applied Ophthalmobiology (IOBA), Spain.

Electronic health record (EHR) refers to the complete set of information that resides in electronic form and is related to the past, present and future health status. EHR standardization is a key characteristic to exchange healthcare information. Health Level Seven (HL7) and Digital Imaging and Communications in Medicine (DICOM) are intensively influencing this process. This chapter describes the development and experience of a web-based application, TeleOftalWeb 3.2, to store and exchange EHRs in ophthalmology. We apply HL7 Clinical Document Architecture (CDA) and DICOM standards. The application has been built on Java Servlet and Java Server Pages (JSP) technologies. EHRs are stored in the database Oracle 10g. Its architecture is triple-layered. Physicians can view, modify and store all type of medical images. For security, all data transmissions were carried over encrypted Internet connections such as Secure Sockets Layer (SSL) and HyperText Transfer Protocol over SSL (HTTPS). The application verifies the standards related to privacy and confidentiality. TeleOftalWeb 3.2 has been tested by from the University Institute of Applied Ophthalmobiology (IOBA), Spain. Nowadays, more than thousand health records have been introduced.

The development of electronic health records marked a fundamental change in the ethical and legal status of health records and in the relationship between the subjects of the records, the records themselves and health information and healthcare professionals—changes that are not fully captured by traditional privacy and confidentiality considerations. The chapter begins with a sketch of the nature of this evolution and places it into the epistemic framework of healthcare decision-making. It then outlines why EHRs are special, what the implications of this special status are both ethically and juridically, and what this means for professionals and institutions. An attempt is made to link these considerations to the development of secure e-health, which requires not only the interoperability of technical standards but also the harmonization of professional education, institutional protocols and of laws and regulations.

AbstractFor research purposes, protected health information is often redacted from unstructured electronic health records to preserve patient privacy and confidentiality. The OpenDeID corpus is designed to assist development of automatic methods to redact sensitive information from unstructured electronic health records. We retrieved 4548 unstructured surgical pathology reports from four urban Australian hospitals. The corpus was developed by two annotators under three different experimental settings. The quality of the annotations was evaluated for each setting. Specifically, we employed serial annotations, parallel annotations, and pre-annotations. Our results suggest that the pre-annotations approach is not reliable in terms of quality when compared to the serial annotations but can drastically reduce annotation time. The OpenDeID corpus comprises 2,100 pathology reports from 1,833 cancer patients with an average of 737.49 tokens and 7.35 protected health information entities annotated per report. The overall inter annotator agreement and deviation scores are 0.9464 and 0.9726, respectively. Realistic surrogates are also generated to make the corpus suitable for distribution to other researchers.

El avance de las tecnologías de la información ha permitido un cambio sustancial en el desarrollo de la Salud, por lo que el uso de estándares de telemedicina como el HL7 y CEN TC 251-13606 permiten que los sistemas de información médica se comuniquen vía mensajes estandarizados facilitando el uso de los mismos. El propósito de este estudio es crear una guía metodológica de intercambio electrónico de información clínica basada en el análisis de los estándares de telemedicina HL7 y CEN TC 251- 13606 para mejorar la eficiencia de la gestión de Historias Clínicas de los pacientes. La metodología consta de 2 fases, la primera plantea el diseño e implementación del modelo de referencia de la Historia Clínica Electrónica, el mismo que define entidades necesarias en la construcción de una Historia Clínica Electrónica, en la fase 2 se define la arquitectura de la historia clínica especificando la estructura y semántica del documento mediante el lenguaje XML, el cual se utiliza en los procesos de gestión de las historias clínicas electrónicas dentro del sistema médico desarrollado. Este sistema permite control clínico a distancia facilitando la interacción médico-paciente. El sistema posee una aplicación web, una aplicación de escritorio y una plataforma hardware e- Salud. La aplicación de la metodología planteada mejora la eficiencia de la gestión de historias clínicas, puesto que el 83.32% de los médicos de la clínica consideran que se agiliza el proceso de acceso, creación e ingreso de historias clínicas y reduce recursos en el proceso de control de pacientes domiciliarios. The advance of Information and Communication Technologies has improved Health Care in last years; by providing new ways of accessing medical information. In particular, the use of telemedicine standards such as HL7 and CENTC 251-13606 allows standard communication, integration, and retrieval of electronic health records among medical systems. This article aims to create a methodological guide for the electronic exchange of clinical information based on telemedicine standards in order to improve the efficiency of electronic health records management. The proposed methodology consists of two phases: The first one states the design and implementation of the reference model of an electronic health records, which defines entities of the electronic health record. In phase 2, this methodology describes electronic health records architecture. The architecture is defined by the structure and semantics of the document using XML. In order to test the proposed methodology, a medical system was implemented that consists of a web application, desktop application, and hardware platform e- Health. This system allows the electronic exchange of clinical information to ease patient-doctor interaction. The results show 83,32% of doctors at the clinic where the system was tested agree the proposed methodology for electronic exchange improves the efficiency of electronic health records management since it speeds up the process of creation and retrieval of an electronic health records. Moreover, the system reduces resources in the control of home patients. Palabras clave: Telemedicina, HCE, HL7, CENTC 251-13606, e-Salud.

This study investigated the most common challenges of human-computer interaction (HCI) while using electronic health records (EHR) based on the experience of a large Russian medical research center. The article presents the results of testing DSS implemented in the mode of an additional interface with the EHR. The percentage of erroneous data for two groups of users (with and without notifications) is presented for the entire period of the experiment and the weekly dynamics of changes. The implementation of CDSS in the supplemented interface mode of the main medical information system (MIS) has had a positive effect in reducing user errors in the data. The results of users' survey are presented, showing a satisfactory evaluation of the implemented system. This study is part of a larger project to develop complex CDSS on cardiovascular disorders for medical research centers.
