Information systems: the key to evidencebased health practice
- Share to:
Increasing prominence is being given to the use of best current evidence in clinical practice and health services and
programme management decision-making. The role of information in evidence-based practice (EBP) is discussed,
together with questions of how advanced information systems and technology (IS&T) can contribute to the
establishment of a broader perspective for EBP. The author examines the development, validation and use of a
variety of sources of evidence and knowledge that go beyond the well-established paradigm of research, clinical
trials, and systematic literature review. Opportunities and challenges in the implementation and use of IS&T and
knowledge management tools are examined for six application areas: reference databases, contextual data, clinical
data repositories, administrative data repositories, decision support software, and Internet-based interactive health
information and communication. Computerized and telecommunications applications that support EBP follow a
hierarchy in which systems, tasks and complexity range from reference retrieval and the processing of relatively
routine transactions, to complex ‘‘data mining’’ and rule-driven decision support systems.
