Purpose of CPOE
Purpose of CPOE
• Automate the patient ordering process in order to manage patient care more effectively and efficiently and as a result improve patient safety and outcomes

• Prevent, reduce, or eliminate medical errors and adverse drug events (ADEs)
• Improve patient safety
• Reduce unnecessary variation in health care • Improve efficiency of health care delivery

Characteristics of CPOE
Attributes of CPOE

• Patient ordering Physician orders are standardized across the organization, yet may be individualized for each doctor or specialty by using order sets. Orders are communicated to all departments and involved caregivers, improving response time and avoiding scheduling problems and conflict with existing orders.

• Patient-centered decision support The ordering process includes a display of the patient's medical history and current results and evidence-based clinical guidelines to support treatment decisions.

• Patient safety features
The CPOE system allows real-time patient identification, drug dose recommendations, adverse drug reaction reviews, and checks on allergies and test or treatment conflicts. Physicians and nurses can review orders immediately for confirmation.
• Optimally the human computer interface is The order entry workflow corresponds to familiar "paper-based" ordering to allow efficient use by new or infrequent users.

Regulatory compliance and security
Access is secure, and a permanent record is created, with electronic signature.
• Portability
The system accepts and manages orders for all departments at the point-of-care, from any location in the health system (physician's office, hospital or home) through a variety of devices, including wireless PCs and tablet computers.
• Management
The system delivers statistical reports online so that managers can analyze patient census and make changes in staffing, replace inventory and audit utilization and productivity throughout the organization. Data is collected for training, planning, and root cause analysis for patient safety events.

• Billing
Documentation is improved by linking diagnoses (ICD-9-CM or ICD-10-CM codes) to orders at the time of order entry to support appropriate charges.

Responsiveness - users are not left hanging
• Response time – prompt response to input
• Reliable – probability of failure-free operation Functions of CPOE
