The Purpose of Clinical Decision Support in Delivery of Healthcare A Clinical Decision Support System (CDSS) is a vital component used in managing patient data. It is a computerized information system designed to support clinical and administrative functions by gathering information from multiple databases for analyses of day to day organizational activities. The systems range from analysis of cost per patient for specific departments to clinical strategic analysis. In their article “The Clinical Support Systems Program: supporting system-wide improvement” Leigh, Long, and Barraclough (2004) reports that the “clinical support system was based on patient-centered systems which is an approach to evidence-based care.

Information includes but is not limited to symptoms, diagnosis, lab test, treatment, and diseases.

The alerts can range from critical labs, physiological, and medication which are then transmitted to the provider by telephone, fax, email, or pager. Another feature of the support system is the Expert Support System (ESS). Its purpose is to take encoded information obtained from experts in a specialty field of medicine, and provide that knowledge to providers for analysis and advice regarding patient care. A third system in CDSS, is the Point-of-Care System. It acts like a repository of information which is gathered and can be entered in real time where care is being provided; containing accurate updated readily accessible patient information....
