Dr. Audet is an Assistant Professor in the Department of Health Policy and the Institute for Global Health at Vanderbilt University Medical Center. In 2008 she joined the Institute for Global Health as a Post-Doctoral Fellow and began research on barriers to HIV testing and treatment uptake in Mozambique. As a faculty member, she has received funding from ViiV Health Care to pilot a male engagement in antenatal care services in rural Mozambique (2011-2014), the Centers for Disease Control and Prevention (through a sub-contract from UCSF) to assess a Positive Prevention clinical training intervention (2010-2014), a career development award (K12) from Vanderbilt University to gather information on traditional treatment practices in South Africa and increase traditional healer referrals of patients with suspected mental illness, TB, HIV, and diarrhea in Mozambique (2012-2015), and the National Institutes of Health (National Institute for Mental Health K01 Award) to assess feasibility of engaging traditional healers as HIV treatment partners in Mozambique (2015-2019). Her research has led to changes in national health policy. Traditional healers, recently recognized as potential allies in health care delivery, use low-literacy patient referral forms piloted by her team in 2012-2013. Male partners, traditionally excluded from antenatal, delivery, and post-natal care in Mozambique, are now formally invited to participate in couples-based services, including HIV counseling and testing after a pilot intervention increased male engagement, leading to higher proportion of women testing for HIV, accepting treatment (if positive), and delivering at the health facility. Working with the Ministry of Health and PEPFAR framework, Dr. PEPFAR framework, Dr. Audet is testing new education and counseling systems to safely and effectively engage family members in the HIV care of patients.
