Information Retrieval in Medicine: The Visual and the Invisible (Information Retrieval im Gesundheitswesen: Das Visuelle und das Unsichtbare)

SummaryEspecially in knowledge-rich domains such as medicine perfect access to the literature is essential for professionals. Unfortunately, especially in knowledge-rich domains it is difficult to achieve perfect access: it is too difficult and too time consuming for users to formulate queries that yield the maximum of relevant documents and a minimum of non-relevant ones. The paper first discusses the challenges of information retrieval in medicine and various existing approaches. To address the challenges two completely opposite approaches are presented. The first supports the user by means of metabrowsing: a visual way of depicting the relations between domain concepts and documents. Metabrowsing relieves the user from the formulation of queries, while leaving him in full control. The second approach aims to minimize the interaction with the user. Information needs and queries are autonomously and proactively formulated by a software-agent who remains invisible to the user. The agent uses the electronic patient record of a particular patient and domain knowledge. As a result, the agent provides the doctor with literature that is relevant with respect to the patient at hand.

Extensible Markup

Abstract:A Template Definition Language (TDL) was developed to share knowledge of how to construct an electronic patient record (EPR) template. Based on the extensible markup language XML, TDL has been designed to be independent of EPR platforms or databases. Our research of TDL was conducted through evaluation of the description of various templates in the currently available EPRs and through comparisons with some electronic clinical guidelines. We conclude that TDL is sufficient for the objective but still needs improvement of the algorithm for describing dynamic changes.

Working Processes

Abstract Background: Client-accessible patient records potentially contribute to patient-centered care by facilitating shared decision-making, enhancing interdisciplinary collaboration, and promoting patient’s autonomy. To achieve this, three Dutch organizations providing ‘care for youth’ developed an electronic patient record (EPR-Youth). EPR-Youth supports working processes of all three organizations and is fully accessible for adolescents and for parents of children aged 0-16 years. Co-creation was chosen as implementation approach for this e-Health intervention that not only intervenes with technology (hardware) but also transforms working processes (orgware) and professional behavior (software). Objective: to investigate the implementation process of EPR-Youth and to determine barriers and facilitators.Methods: a mixed methods design was used. To guide the process evaluation, Pfadenhauers’ Context and Implementation of Complex Interventions framework and Proctor’s theoretic framework on implementation were used to define implementation outcomes and describe setting and context. Target groups were parents, adolescents, professionals using EPR-Youth, and all stakeholders in the implementation process.Results: Barriers in the implementation process of EPR-Youth were the complexity of collaboration between stakeholders and the lack of clarity about leadership and project planning. Facilitating factors were clarifying the vision, setting deadlines, and a pioneering spirit.Acceptability of the client-portal was high among all users. Adoption of the client-portal was highest among parents of children aged 0-3 years and among higher educated parents.Professionals’ doubts about user-friendliness and about the match with vision and working processes were partly due to lack of knowledge of all system functionalities. Conclusion: The implementation of EPR-Youth, the first Dutch electronic patient record facilitating both preventive child health and youth care, was successful on ‘hardware’ level. To complete implementation on ‘software’ and ‘orgware’ level, client information needs attention, as well as training of professionals. Further research is needed to gain insight into barriers to access the client-portal. Although co-creation was an essential ingredient to reach project goals, situational leadership with more direction at the start and room for disruption is needed to guide this process.

Discharge Summaries

AbstractData are presented on the use of a browsing and encoding utility to improve coded data entry for an electronic patient record system. Traditional and computerized discharge summaries were compared: during three phases of coding ICD-9 diagnoses phase I, no coding; phase II, manual coding, and phase III, computerized semiautomatic coding. Our data indicate that (1) only 50% of all diagnoses in a discharge summary are encoded manually; (2) using a computerized browsing and encoding utility this percentage may increase by 64%; (3) when forced to encode manually, users may “shift” as much as 84% of relevant diagnoses from the appropriate coding section to other sections thereby “bypassing” the need to encode, this was reduced by up to 41 % with the computerized approach, and (4) computerized encoding can improve completeness of data encoding, from 46 to 100%. We conclude that the use of a computerized browsing and encoding tool can increase data quality and the percentage of documented data. Mechanisms bypassing the need to code can be avoided.

Problems associated with the improve ment of information retrieval for open environment are considered and the need for it’s semantization is grounded. Thecurrent state and prospects of development of semantic search engines that are focused on the Web information resources processing are analysed, the criteria for the classification of such systems are reviewed. In this analysis the significant attention is paid to the semantic search use of ontologies that contain knowledge about the subject area and the search users. The sources of ontological knowledge and methods of their processing for the improvement of the search procedures are considered. Examples of semantic search systems that use structured query languages (eg, SPARQL), lists of keywords and queries in natural language are proposed. Such criteria for the classification of semantic search engines like architecture, coupling, transparency, user context, modification requests, ontology structure, etc. are considered. Different ways of support of semantic and otology based modification of user queries that improve the completeness and accuracy of the search are analyzed. On base of analysis of the properties of existing semantic search engines in terms of these criteria, the areas for further improvement of these systems are selected: the development of metasearch systems, semantic modification of user requests, the determination of an user-acceptable transparency level of the search procedures, flexibility of domain knowledge management tools, increasing productivity and scalability. In addition, the development of means of semantic Web search needs in use of some external knowledge base which contains knowledge about the domain of user information needs, and in providing the users with the ability to independent selection of knowledge that is used in the search process. There is necessary to take into account the history of user interaction with the retrieval system and the search context for personalization of the query results and their ordering in accordance with the user information needs. All these aspects were taken into account in the design and implementation of semantic search engine "MAIPS" that is based on an ontological model of users and resources cooperation into the Web.
