HORIZON LIMS in Public Health Laboratories

Public Health Laboratory TestingChemWare is one of the few LIMS providers offering a single, off-the-shelf system that can address all of the varied needs of the Public Health Laboratory community. HORIZON’s interoperability facilitates the management of data across laboratory departments and the secure electronic transfer of data to other local, state, and federal agencies, including the CDC. HORIZON LIMS has been successfully validated for compliance with PHIN, PHLIP, and LRN-B interoperability standards, enabling secure, reliable, and time-sensitive exchange of public health test orders and test results between the laboratory and other public health agencies.

HORIZON provides test code definition, workflow modeling, and other business rule maintenance within a very powerful, built-in Rules Engine tool. The Rules Engine allows users to configure even the most complex public health test workflows such as TB and Influenza, handle mapping and maintenance of LOINC and SNOMED nomenclature, and manage inventory of media, kits, and forms.

ChemWare is a sustaining member of the APHL and an active participant in the initiatives to establish electronic data exchange and interoperability standards for the Public Health Information Network, data providers, and data consumers. ChemWare provided significant input into the draft specification for the XML-based data exchange requirements of the Environmental Response Laboratory Network (ERLN).

Alaska State Public Health Laboratories (ASPHL)
process 75,000 samples annually. Many of these samples undergo multiple tests. The highest sample count is in clinical testing. Other disciplines include chemistry (R&D), bioterrorism, virology, research (assisting with an outbreak), and very limited food testing. An increase in the number of test requests submitted by the Alaska Native Medical Center is quite possible or even likely. Two laboratory locations, Anchorage and Fairbanks, process mutually exclusive types of tests. The Fairbanks laboratory is strictly virology.

Alabama Department of Public Health
includes three regional laboratories, located in Montgomery, Birmingham, and Mobile, that provide laboratory services to ADPH County Health Department Clinics and contract clinics at approximately 110 sites in 67 counties.  The majority of specimens are submitted by the ADPH Clinics, with the rest coming from approximately 1600 non-ADPH providers (hospitals, private labs, physicians, etc.) and the general public.
