Occupational Health Record-keeping System (OHRS) is part of the Clinical Information Support System (CISS) portal framework and the initial CISS partner system. OHRS is a web-based application that enables employee occupational health staff to create, maintain, and monitor medical records for VA employees and generate national, Veterans Integrated Service Network (VISN), and site-specific reports.The focus of OHRS is to collect clinical data for wellness, medical surveillance, and appropriate treatment of work-based injury or illness. OHRS will capture and store information on patient encounters, such as encounter type, purpose, status, provider, and other pertinent clinical data obtained during the patient visit. Users with appropriate security privileges are allowed to add and sign or co-sign the encounter and, if needed, perform scheduled and unscheduled reporting on items such as vaccination rates, vaccination and immunity statuses. The OHRS application does not share patient-specific data, but will collect data elements limited to information deemed critical to the Occupational Health delivery of care processes in the OHRS database. Employee data is obtained from the central Personnel and Accounting Integrated Data System (PAID) while volunteer information is obtained from the Voluntary Service System (VSS). Other Non-Paid and non-VSS data is collected by direct data entry into OHRS at the time of the patient encounter. OHRS is further designed to document, track and report immunizations administered to other Federal Agency employees outside of VA.
