Australian HIV testing policies have always recommended pregnant women be tested on the basis of risk assessment or clinical [2]Pertaining to or founded on observation and treatment of participants, as distinguished from theoretical or basic science. indication. With a low seroprevalence among Australian women, universally offering antenatal HIV testing has not been seen as appropriate or cost-effective. Although some have argued HIV testing be routinely offered, it has never been policy.
HIV positive women have often had very strong opinions on this, for the obvious reason that many women have had direct experience of receiving a positive diagnosis during pregnancy, or have had children while HIV positive. Being diagnosed with HIV while pregnant can be a distressing or traumatic experience, and positive women have drawn attention to how testing policies directly affect women’s wellbeing, and the urgent need for appropriate services and approaches.
A recent analysis by Graves et. al. suggested that there may be economic arguments for routinely offering antenatal HIV testing1. Some now argue that current policy should be revised.
The National Association of People Living with HIV/AIDS (NAPWA), through its NAPWA Women’s Network, has been seeking the views of HIV positive women on this subject, and have contributed directly to this debate.
NAPWA has:
There has been a growing recognition among policy-makers that HIV positive women’s views in this are not just legitimate, but crucial.
NAPWA retains major concerns about the practical implementation of routine testing in the antenatal setting. There are significant shortcomings in current practice, including serious deficits in support and referral services. Problems include:
Accordingly, there are a number of principles NAPWA would like to see reflected in these deliberations.
HIV positive women need to be consulted as widely as possible, and directly included on working groups which set up to develop, write or implement guidelines or protocols. It is through gaining insight from women who have directly experienced a positive diagnosis in pregnancy, for example, that policymakers can develop acceptable and relevant protocols.
Women report the current situation as “ad hoc” and sometimes contradictory. Anecdotally, women’s experiences of testing in pregnancy vary greatly between states. Successful and meaningful policies and guidelines need to consider what is best for both the mother and her infant, and should be nationally recognised and followed.
Whether HIV screening is to be routinely or universally offered, or whether the status quo remains, NAPWA places great emphasis on support and referral services. Many women report current services to be patchy, sometimes inadequate or even non-existent. Any move expansion of testing brings the obligation to provide adequate and appropriate support and clinical referral services. This would be an important condition of any support from NAPWA for changing the current arrangements. It may be possible to set up or contract a specific peer referral service that positive women could access in pregnancy for support or advice.
Experience of the pre and post test information was extremely variable. Some women reported feeling isolated; not always made aware of the risks and benefits, pros and cons of testing, and some clinicians had a poor knowledge of HIV treatments options and clinical outcomes. It is not uncommon for women to report they are tested without consent or knowledge.
It was suggested that:
Screening protocols, training and guidelines should be targeted to all those involved in clinical care, including midwives, GPs and specialist physicians.
There are still concerns among some women that universally offering entails a potentially high cost for the benefit gained. In practice, such a policy is likely to incur “hidden” or unexpected costs in implementation, and this needs be taken into account.
