Redwood MedNet -
A non-profit health information data network service provider based in Ukiah,
California. Redwood MedNet was founded in 2005 to electronically interconnect
participants in health care by enabling clinical data interoperability, and to
interoperate with national health information technology initiatives. Redwood
MedNet began delivery of electronic clinical data in Healdsburg in 2008, and
now operates over 100 interfaces and has delivered more than a million clinical
messages into EHRs. From 2005 - 2007 during the Prototype Architecture project
Redwood MedNet was the fiscal agent for the
Mendocino HRE project.

In software development the reference implementation is the standard baseline
starting point from which all other implementations begin, including customized
and next generation versions.

In computing, remote access refers to logging into a computer network from a
remote location, such as logging onto your office computer from home.
Remote Presence -
Generic term for use of video conference technology to enable remote
participation in a meeting. In health care remote presence refers to use of
video conference tools to enable remote clinical consultation.

Representational State Transfer (REST) is a software architecture for a
distributed hypermedia environment, such as the Internet. REST was defined
by Roy Fielding. See also RFC
2616. REST is a way to create, read, update or delete information on a
server using simple HTTP calls. It is an alternative to more complex
mechanisms like SOAP, CORBA and RPC. A REST call is simply an HTTP request
to the server. Services that conform to the REST constraints are said to be
In computer network engineering, a Request for Comments (RFC) is a memorandum

The Redwood Health Information
Collaborative (RHIC) was formed in 2005 by the
County Department of Public Health. Funded by an "Information Links" grant
from the Robert Wood Johnson Foundation,
RHIC convened a Steering Committee to investigate the policy implications of
data exchange among rural health care providers and Public Health in the
Mendocino region. The Steering Committee completed its grant funded
deliverables in 2007. Redwood MedNet continued the monthly meetings until
December 2009 as a free public webinar, with presentations on health
technology and policy. The

("ree-oh") Regional Health Information Organization is
a term introduced in 2004 for an HIE operating in a geographically contiguous
region. The term had limited usefulness due to the many HIEs that are not
strictly regional (e.g., the Veterans Administration, the Indian Health
Service, Kaiser Permanente, etc.). To be fair, RHIO displaced the prior term
LHII, which was a result of faulty comparison of local health information
exchange services to local telephone circuit branch exchanges. Both RHIO and
LHII are a result of imagining that the topology for health data exchange must
be community-centric. After a brief period of initial use, the term RHIO fell
into disuse and is now an historic footnote in the evolution of health data
exchange services. See

Record Locator Service, a specialized implementation of a Master Person Index
(MPI) proposed by Connecting for
Health, in which the MPI implementation is subordinated to appropriate
privacy, security and other health policy imperatives as defined by the
Framework. An RLS holds information about where health data can be found,
but not the health data itself. Thus the RLS structurally separates knowing
who the information is about from knowing what the information
is, which inherently reduces the risk of privacy spills. See

In computer science a remote procedure call (RPC) allows a computer program to
execute a subroutine or procedure in another address space (commonly on another
computer on a shared network) without the programmer explicitly coding the
details for the remote interaction.
Resource and Patient Management System is an integrated EHR developed by the
Indian Health Service for the management of clinical, business and
administrative information in healthcare facilities ranging in size from
small part time clinics to hospitals. Architecturally, RPMS is a cousin
(literally, a programming fork two decades ago) of the VistA EHR operated by
the VA, and retains substantial shared code.

An RS-232 serial port was once a standard feature of personal computers,
used for connection to modems, printers, mice, data storage, uninterruptible
power supplies, and other peripheral devices. However, low transmission
speed, large voltage swing, and large standard connectors motivated
development of the universal serial bus, which has displaced RS-232 from
most of its peripheral interface roles. Many modern personal computers have
no RS-232 ports and must use an external converter to connect to older
peripherals. RS-232 devices are still found, especially in industrial
machines or scientific instruments.
