Clinical decision support system case study

Algorithms for learning Bayesian networks from data have evolved in the past two decades but are also primarily used in research applications Cooper and Herskovits, ; Buntine, ; Moore and Lee, Using these audiotapes, we distilled five central areas of activity that are essential to the goal of increased adoption of CDSSs for evidence-based medicine.

Develop shareable, machine-readable repositories of executable guidelines that are linked to up-to-date evidence repositories.

Analysis of clinical decision support system malfunctions: a case series and survey.

All conference sessions were audiotaped. Therefore, one key step in developing more effective CDSSs is to generate not simply more clinical research evidence, but more high-quality, useful, and actionable evidence that is up-to-date, easily accessible, and machine interpretable.

Refer to statistical and machine learning textbooks for a review of these topics Duda et al. In the meantime, the best electronic resources for evidence-based medicine include the Cochrane Library, Best Evidence, and Clinical Evidence, resources that cull the best of the literature to provide an up-to-date solid foundation for evidence-based practice.

No longer should CDSSs be thought of as stand-alone expert systems. Elements of these techniques can be used in conjunction with the classifiers discussed here in a number of different ways, but they do not constitute classifiers themselves.

However, selecting the sources and integrating this knowledge into a functional system is not a trivial task. Recommendations for Clinical and Informatics Researchers Conduct better quality clinical research on the efficacy, effectiveness, and efficiency of clinical interventions, particularly in primary care settings.

On the basis of discussions at the conference, we identify six specific recommendations for action: In contrast, if the research literature were available as shared, machine-interpretable knowledge bases, then CDSSs would have direct access to the newest research for automated updating of their knowledge bases.

First, the efficacy studies of clinical practice that form the basis for evidence-based medicine constitute only a small fraction of the total research literature. The use of clinical decision support systems to facilitate the practice of evidence-based medicine promises to substantially improve health care quality.

Although many studies have shown the efficacy of CDS systems, several recent studies have found that implementation of CDS may not improve quality of care Romano and Stafford, and, in some cases, may result in adverse outcomes Han et al.

For example, if an expert can articulate all the rules that were used to make a diagnosis and how they were chained, then a system based on these rules can potentially explain its reasoning in a way that clinicians would be able to understand and accept Clancey, For domains in which structured data are abundant, and the decisions are made at times in which a snapshot of these data could help identify specific patterns, pattern recognition algorithms from the fields of statistical and machine learning can be of great value.

On the basis of the expert panels and discussion sessions at the Congress, we recommend the following steps for researchers, developers, and implementers to take in the five areas of activity essential to increasing adoption of evidence-adaptive CDSSs. The earliest systems for medical diagnosis, in the s, used Bayesian probability models as discussed in Chapter 2relying on either databases of patient data or subjective estimates of prior and conditional probabilities from human experts.

Continue to develop better methods for synthesizing results from a wide variety of study designs, from randomized trials to observational studies. Many research and policy issues concerning these research networks—from the standardization of data items to data ownership and patient privacy—are active areas of inquiry.

Clinical decision support system CDSS. We conclude with a discussion on current directions for the field.

Automation of these tasks remains an open area of research. Process The speakers for the Evidence and Decision Support track are listed at the end of this paper. Find articles by Paul Gorman Robert A. Evidence-adaptive CDSSs also need to interface with up-to-date repositories of clinical research knowledge.

Another omission is the discussion of optimization techniques such as genetic algorithms and evolutionary computing Koza,and formalism extensions such as fuzzy logic Zadeh, and rough sets Pawlak For example, Shwe and colleagues Swhe et al.

Clinical Decision Support Systems for the Practice of Evidence-based Medicine

Clinical decision support (CDS) provides clinicians, staff, patients or other individuals with knowledge and person-specific information, intelligently filtered or presented at appropriate times, to enhance health and health care.

Complete records allow CDS systems to help with diagnoses and track. Feb 19,  · Background: The use of clinical decision support systems to facilitate the practice of evidence-based medicine promises to substantially improve health care quality. Objective: To describe, on the basis of the proceedings of the Evidence and Decision Support track at the AMIA Spring Symposium.

A clinical decision support (CDS) system is a computer-based system that analyzes available data to guide people through a clinical decision-making process.

The availability of data may be considered to be the most fundamental prerequisite of a CDS, because analysis and guidance depend on it. Although clinical decision support is a key patient safety strategy, it may also have unintended consequences.

Investigators analyzed clinical decision support system malfunctions and surveyed chief medical informatics officers about such incidents. Nearly all health systems experience decision support malfunctions, and the majority of respondents' health systems.
