Safety Recommendation
The Australian Transport Safety Bureau recommends that the Civil
Aviation Safety Authority review the medical certification
standards to consider the potential increased significance of
diastolic blood pressure to the risk of a cardiac event in
applicants for an aviation medical certificate.
CASA has been applying a cardio risk screening tool for almost
ten years, which is based on internationally recognised research
and provides an appropriate balance in assessing risk
factors.
There are a range of diagnostic tools that provide an indicative
measure of possible cardiac events including body mass index and
other factors. While there are risks associated with all screening
methods, these need to be balanced against the false positive
results found in the screening procedures.
The Authority will ensure that its medial [sic] certification
assessment process remains consistent with current medical best
practice and will continue to monitor research into the medical
significance of diastolic blood pressure to the risk of a cardiac
event.
CASA is also in the process of establishing a review of the
literature relating to this subject. The results of the review will
determine whether CASA changes its current screening tool.
ATSB Note:
As at 26 March 2008, no further advice had been received from
CASA on their review and any consequent changes to its screening
tool. The ATSB reclassifies the recommendation as Closed -
Partially Accepted.
