System (CHCS)), the approved Service-level, computer-based systems (such as the
Theater Army Medical Management Information System (TAMMIS) or the Shipboard
Automated Medical System (SAMS)), and manual collection systems. When available,
Automated Information Systems (AIS) will always take precedence over manual systems.
c. Automated Audit . The CHCS, the Ambulatory Data System (ADS), and the
record of treatment complete the audit trail for automated systems. The patient
appointment roster, sign in log, daily tally reports, monthly clinic report, and the record of
treatment provide the audit trail in manual data collection systems.
1-10. DOD STANDARD SYSTEMS
a. Composite Health Care System. The WWR in CHCS version 4.5 calculates
Bed Days, Sick Days, Live Births, visits, and other statistical data based on day-to-day
information entered into the CHCS. The CHCS On-Line User's Manual provides
information regarding data entry, audit, verification, and reporting.
b. Ambulatory Data System . The ADS complements the functions of the CHCS
and provides patient-level diagnostic and procedural detail on patient encounters. The
ADS provides a number of output reports that may validate CHCS and manual data
collection systems. The ADS User's Manual provides information regarding data entry
and available output reports. Not all care scenarios can be covered. However, the Current
Procedural Terminology (CPT) Evaluation and Management (E/M) codes provide an
1-11. ARMY UNIQUE SYSTEMS
a. The Army uses a three-tier system of reporting. At the first level, reliance is
placed on standardized automation systems (i.e., CHCS and TAMMIS). The second level
consists of PC-based systems (i.e., Medical Summary Reporting System (MSRS)), and
the third level is manual preparation of reports.
b. Theater Army Medical Management Information System. TAMMIS
provides patient information and logistical management functions to deployed hospital
units providing medical care in the field environment. The TAMMIS Medical Patient
Accounting and Reporting (MEDPAR) subsystem automatically tracks the majority of the
inpatient data required for the WWR. However, data pertaining to clinic visits by
outpatients and some inpatients are not automatically captured by the system. Procedures
should be established within the unit to obtain report feeder information for outpatient clinic
and ancillary service workload. The TAMMIS User's Manual provides information
regarding data entry, audit, verification, and reporting.
c. Medical Summary Reporting System. The MSRS is a PC-based data
recording and reporting system which allows for data entry, calculation, and reporting by
