CDS
Clinical decision support (CDS) refers broadly to providing clinicians or patients with clinical knowledge and patient-related information, intelligently filtered or presented at appropriate times, to enhance patient care. Clinical knowledge of interest could range from simple facts and relationships to best practices for managing patients with specific disease states, new medical knowledge from clinical research and other types of information.

CDS components
There are several key components of a good clinical decision support system. [1]
Order set
An order set is a group of related orders which a physician can place with a few keystrokes or mouse clicks. An order set allows users to issue prepackaged groups of orders that apply to a specified diagnosis or a particular period of time. Using order sets reduces both time spent entering orders and terminal usage.
Medication decision support
- Adverse drug reactions
- Basic Dosing Guidance for medications in CPOE
- Formulary decision support
- Duplicate Therapy Checking
- Advanced Dosing Guidance in CPOE
- Patient Characteristic dosing support
- Medications to be avoided in the elderly
- Medications requiring dosage adjustments in renal insufficiency
- Medications requiring dosage adjustments in hepatic disease
- Medications to be avoided during pregnancy
- Medications to be avoided while breastfeeding
- Vaccination contraindications
- Common Corollary orders
- Detection of Adverse Mediation-Related Events
Non-medication safety rules
CDS benefits
Results indicate the potential of CDS to improve the quality of care. These are good reasons for institutions to adopt CDS, but they should do so at their own pace and volition.
- Better clinical decision making leads to better practices.
- Reduces the medication errors
- Promote preventive screening and use of evidence based recommendations
- Cost reduction and increased patient convenience
Interaction models
An interaction model is a set of rules for making clinical decisions. The rules are based on a large collection of medical knowledge and an accurate computer representation scheme.
Artificial intelligence
Artificial intelligence is a system that was developed by a team of system engineers and clinicians. The system would take some of the workload from medical teams by assisting the physicians with tasks like diagnosis & Therapy recommendations.

Sample Decision Support Content
- Diabetes CDS Content
- Drug-Drug Interaction Rules
- Clinical Reminders from Beth Israel/Deaconess Medical Center in Boston
- Symptom Triage Decision Support for Consumers (example: "Chest Pain") [2]
- Weight-based Heparin Dosing Guidelines
- Flowchart-based decision support sample content
- Preventive care reminders
CDS Implementation
CDS should be designed to provide the right information to the right person in the right format through the right channel at the right time.
At the stage of planning for any new health IT system, there are some considerations and steps that should be followed to guarantee the system success; such as identifying the needs and functional requirements, deciding whether to purchase a commercial system or build the system, planning for encouraging physicians to use CDS, designing a system to evaluate how well the system has addressed the identified needs[1].

Success criteria estimates
To estimate the success of the system we should look at the following points[3]:
- System quality.
- Information quality
- Usage
- User satisfaction
- Individual impact
- Organizational impact.
