Capturing Ancillary Documentation using CHCS

CHCS is the major information management system for handling pharmacy, laboratory and radiology as well as scheduling patient appointments.The Composite Health Care System (CHCS) allows clinicians to electronically perform patient appointment processes and scheduling, order laboratory tests, authorize radiology procedures and prescribe medications.

CHCS serves as the foundation for the Department of Defense's electronic health record, AHLTA. Through the Electronic Health Record (EHR), CHCS enables DOD providers to document patient's health information and history, electronically order laboratory and radiology tests/services, retrieve test results and order and prescribe medications. CHCS's Computerized Physician Order Entry function continues to safeguard the care provided to our beneficiaries by reducing the risk of illegible orders and performing drug interaction and appropriateness checks.
