MAC -
[1] Media Access Control, a unique address identifier assigned
to network devices. [2] Medicare Administrative Contractor.
Malware -
Short for "Malicious Software." Malware is a general term for a wide range of
intrusive or hostile computer software. Malware includes computer viruses,
worms, trojan horses, spyware, adware, most rootkits, and other malicious
programs. Malware is used to disrupt computer operation, gather sensitive
information, or gain access to private computer systems.

Medical Records Institute -
The Medical Records Institute sponsored the annual TEPR (Towards Electronic
Patient Records) conferences for 25 years. The final conference was held in
Palm Springs in February 2009. Later that month the leadership of the MRI
launched the mHealth Initiative, focused
on the emergence of mobile healthcare devices.
Medi-Cal -
The local California name for the Medicaid Program. See
DHCS
MedInfo -
World Congress on medical informatics held every two years:
MedInfo 2013 was held in Copenhagen,
Denmark; MedInfo 2015 will be in Sao Paulo, Brasil; and MedInfo 2017 will be
in Beijing, China. See

Megabyte -
A semi-ambiguous multiple of the unit byte.
Depending upon the context, a megabyte is 1,000 kilobytes (IEEE and ISO
digital standards) or 1,024 kilobytes (memory circuits with a binary
architecture). As the variance is small, and as the international electronic
standards community has shown no discipline for sorting out the terms, they
are ambiguously interchanged. See

Mendocino HRE -
Mendocino Health Records Exchange
was the transitional name of two demonstration projects on electronic health
data interoperability in Mendocino County, California: [1] the
Connecting for Health Record
Locator Service project was active from June 2005 to April 2006; and
[2] the Connecting
for Health NHIN Architecture Prototype project was active from November
2005 to January 2007. In both projects health data interoperability solutions
developed by the Mendocino SHARE project were featured in nationwide
demonstrations. As a subcontractor on the federal contract "Mendocino HRE" was
a DBA of Redwood MedNet. The business name "Mendocino HRE" was retired by
Redwood MedNet after the completion of the Prototype Architecture project. The
community successor to the interoperability services investigated by the
Mendocino HRE effort is Redwood MedNet.

Mendocino SHARE -
The Mendocino SHARE
Project was active during 2003 - 2006 in Mendocino County, California. Mendocino
SHARE was initially conceived in 2003 as a community wide health data exchange
service modeled on the Santa
Barbara County Care Data Exchange (SBCCDE). Mendocino SHARE was funded by
HRSA to develop a community technology infrastructure. In 2005, after two years
of software development to create a community-based interoperability service,
the Mendocino SHARE partnership repurposed the remaining federal grant funds
for twelve community partners to purchase software for site level use at
six of the community partner sites. After the third year of HRSA funds were
disbursed, the Mendocino SHARE project was closed. See

MRP -
Material Requirements Planning (MRP) is a production planning and inventory
control system used to manage manufacturing processes. MRP arose in the 1960s
out of the Toyota Manufacturing Program. In the 1980s this evolved into MRP-II
with the addition of master schedule and capacity planning components. In the
1990s MRP-II evolved further into ERP.

MRP-II -
Manufacturing Resource Planning (MRP-II) is a second generation production
planning and inventory control system that arose from limitations in MRP. While
MRP was primarily concerned with materials, MRP-II was concerned with the
integration of all aspects of the manufacturing process, including more agile
and adaptive master scheduling of materials plus finance and capacity planning.
In the 1990s MRP-II evolved further into ERP.

MU -
Meaningful Use (MU) is a term introduced by the 2009 HITECH legislation, which
appropriated incentive funds for CMS to distribute for the "adoption and
meaningful use of certified EHR technology" (CEHRT). In response, CMS issued
guidance "for the definition of meaningful use to be consistent with applicable
provisions of Medicare and Medicaid law while continually advancing the
contributions certified EHR technology can make to improving health care
quality, efficiency, and patient safety."
