I deleted an article (mistakenly created as a category) with the same title as this one: I have pasted the text below in case there are elements of it which should be incorporated here by people who know the subject better than I. Article text follows:

Decision Support system
Decision Support system is a “computer-based information system which helps the user to make better decisions, improved quality of care and educe cost without loss of quality”.

According to Wyatt and Spiegelhalter clinical decision support (CDS) systems are “active knowledge systems which use two or more items of patient data to generate case-specific advice.” (J. H. Van Bemmel, et al., 1997)

Computerized Decision Support System
Computerized Decision Support systems are consultation system that uses artificial intelligence techniques knowledge and solving problems. Computer based decision making systems help healthcare providers use information to make better decisions have been developed and implemented. These decision aids are designed to improve the quality and reduce the cost of healthcare.

Clinical Decision Support (CDS) system integrated with the Computer based Patient Record (CPR) support clinician decision making. CPR with extensive CDS capabilities provides clinicians with more complete and more comprehensive information from multiple sources. “UHN established a CDS program, focused on providing clinicians with CDS tools that can improve the quality and efficiency of care. The CDS clinical advisory committee (CAC) is responsible for the development and approval of all CDS initiatives”. (Peacock, Sinert and Smith, 2004).

Clinical Data Warehouse (CDW) is another technology used. CDW is a bridge between patient centered decision making and population based healthcare decision making. CDW includes data from the CPR and other enterprise systems, stored on a separate system and reorganized to support retrospective analysis. It does not contain a mirror image of the data in the transactional system; rather, it contains a subset of data useful for its specific purposes. CDW contain the results of the clinical processes that occurred. CDW is a critical tool to measure.

Benefits of using Decision Support System
Decision support system have many benefits, the tools use in DSS can help in many ways:

Each of the decision support tools (CPR, CDSS, and CDW) is valuable alone, but together they are a powerful combination for improved patient outcomes. Decision support is important to all phases of the clinical process, from assessment and planning to intervention and evaluation. A comprehensive CDSS should assist the clinical at every point of care, providing everything from rapid access to relevant knowledge bases, to interactive criteria based alerts at the time of order entry and outcome indicator reports. Clinical data warehouse is crucial throughout the process. It allows UHN to quickly identify and assess decision support opportunities by generating analytical reports that detail clinical practice. (Peacock, Sinert and Smith, 2004).

The decision support system helps the organization to take right decision at the right time through the extraction of historical and current datas in a system.Decision support system also speeds up in making decisions and also helps in solving ill-structured problems.Decision support system improves the effeciency of the managers and the proffessionals in making decisions and also how to control the activities of the organization.(Raju Kumar Singh,2011)(12.176.17.58 (talk) 21:36, 19 January 2011 (UTC))
