We do have over 2 years experience in using this test and
are currently evaluating the operational use of this in over 200 patients. We
do this test on a Azeda Tli analyser based in the laboratory. Preliminary data
analysis shows that it has a high negative predictive value around 99% in those
presenting with preterm labour. This is in keeping with previous studies.
Although this is an expensive test, preliminary evaluations suggest there is a
significant cost saving by way of decreased length of average hospital stay,
use of steroids, tocolysis and U/SS since the test has been introduced.
The obstetricians and midwives find this test very useful in making a decision
to discharge patients with a negative test and who otherwise have low clinical
risk of premature preterm birth. Midwives and obstetricians also
find a negative useful in reassuring the patients and their
families.
One of our regional hospitals (Greymouth hospital - on the
other side of the Southern Alps) also use this test and find it very
useful, as it avoids helicopter transfer of patients with a negative test
to a tertiary hospital and thus probably considerable cost savings.
