WHAT IS A MEDICAL REVIEW OFFICER ASSISTANT?

As demands for a safe and drug-free workplace grow, federal requirements and a burgeoning work load
require that many medical review functions be carried out by Medical Review Officer Team members under
the direct supervision of a certified Medical Review Officer.  A certified MRO Assistant is a highly trained and
qualified non-physician staff member who demonstrates an understanding of the MROA competencies as put
forth by the Medical Review Officer Certification Council and DOT regulation 49 CFR Part 40.
"The MRO may be assisted by one or more staff. An MRO assistant performs administrative functions and
does not perform any portion of the interview between the MRO and donor. The administrative functions
typically include receipt and sorting of test forms, presenting non-negative and fatally flawed files to the MRO
for review, and distribution of reports to clients.

Some MRO assistants also call donors, confirm their identity, and then transfer the calls to the MRO. Some
MRO assistants are also involved in the corroboration of medical explanations that donors may present to the
MRO. An MRO assistant ­should be detail oriented, well organized, and reliable.

Under the U.S. Department of Transportation (DOT) drug and alcohol testing procedures, the MRO must
supervise the MRO assistant. This supervision must include personal oversight of that assistant's work;
personal involvement in evaluating, hiring, and firing the assistant, line authority over the assistant for
decisions, direction, and control; and regular contact and oversight concerning drug testing program matters.
The MRO's supervision and control cannot be superseded by or delegated to anyone else with respect to test
result review and other functions performed by the MRO assistant."
