The Mortality Medical Data System (MMDS) is used to automate the entry, classification, and retrieval of cause-of-death information reported on

and in many other countries. The
National Center for Health Statistics (NCHS) began the system's development in 1967.
The system has facilitated the standardization of mortality information within the United States, and
ACME has become the de facto international standard for the automated selection of the underlying cause of death from multiple conditions listed on a death certificate.
System components
The MMDS system consists of the following components, and is itself part of th
National Vital Statistics System
MICAR
There are two Mortality Medical Indexing, Classification, and Retrieval components.
* SuperMICAR automates the MICAR data entry process. This program is designed as an enhancement of the earlier PC-MICAR Data Entry program. Super-MICAR is designed to automatically encode cause-of-death data into numeric entity reference numbers.
* MICAR200 automates the multiple cause coding rules and assigns
''International Statistical Classification of Diseases and Related Health Problems'' (ICD) codes to each numeric entity reference number.
ACME
The Automated Classification of Medical Entities program automates the underlying cause-of-death coding rules. The input to ACME is the multiple cause-of-death codes (
ICD) assigned to each entity (e.g., disease condition, accident, or injury) listed on cause-of-death certifications, preserving the location and order as reported by the certifier. ACME then applies the

(WHO) rules to the
ICD codes and selects an underlying cause of death. ACME has become the de facto international standard for the automated selection of the underlying cause of death.
TRANSAX
The TRANSlation of Axis program converts the ACME output data into fixed format and translates the data into a more desirable statistical form using the linkage provisions of the
ICD. TRANSAX creates the data necessary for person-based tabulations by translating the axis of classification from an entity basis to a record basis.
