Role of a Medical Review Officer (MRO)
What is an MRO?
Under Subpart 99B of the Civil Aviation Safety Regulations 1998 a DAMP medical review officer (MRO) is a registered medical practitioner with:
- competence in the field of interpreting drug and alcohol test results
- knowledge of substance use disorders
- knowledge of the contents of Subpart 99B.
How does my organisation locate a DAMP MRO?
The Australasian Medical Review Officers Association (AMROA) maintains a list of accredited MROs. Please note that this is not an exhaustive list. An organisation may consult a medical practitioner of their choice, as long as they meet the competence and knowledge requirements set out above.
Note: to assist organisations meet the requirement that an MRO be familiar with the contents of Subpart 99B, CASA has developed a factsheet Quick reference guide for a DAMP Medical Review Officer (MRO) which organisations can present to any MRO they consult under their DAMP.
When must my organisation consult an MRO?
Under a Subpart 99B compliant DAMP, an organisation must consult a MRO in the following three circumstances:
- If a confirmatory drug test conducted under the organisation's DAMP returns a positive result - to determine if the presence and level of the testable drug detected by the test could be the result of legitimate therapeutic treatment or some other innocuous source
- for example, an over-the-counter cold and flu tablet could cause a positive result for amphetamines and a prescribed pain killer could contain detectable levels of codeine.
- If a SSAA employee has failed to give a body sample for AOD testing due to a medical condition, an MRO must review the relevant medical information to confirm that there is a valid medical reason
- for example, a lung condition could prevent a person from providing a breath sample.
- To determine if the employee is fit to resume performing or being available to perform a 'safety sensitive aviation activity' (SSAA) after they have been prevented from doing so following a 'suspension event'.
What is a 'suspension event'?
Subpart 99B requires that a DAMP organisation must not permit an employee to perform, or be available to perform, an applicable SSAA, in the following circumstances or 'suspension events':
- If a positive result for a confirmatory drug test has been recorded (under either the DAMP or CASA testing programs) and a MRO has ruled out that the result recorded could not be due to legitimate therapeutic treatment or some other innocuous source.
- If the organisation is aware that a SSAA employee after having been required to take a drug or alcohol test:
- refused to take the test
- interfered with the integrity of the test.
