Aim: To assess the attitudes of Australian health professionals to tamoxifen as a risk-reducing medication (RRM). To identify barriers to prescription due to workforce issues, risk assessment skills, willingness to initiate or monitor while on RRM.

Method: Members of relevant medical organizations in Australia and New Zealand were invited to participate in a web-based survey aiming to accrue 240 participants.

Results: 100 participants were recruited including 33 genetic health professionals, 32 medical oncologists and 20 surgeons following which it was closed due to slow accrual. 99% of respondents perceived tamoxifen to be effective.

Overall respondents felt that assessing a patient's personal risk of breast cancer should be performed by cancer-specific services such as cancer geneticists (74%) or medical oncologist (66%) rather than GPs (26%). Genetic health professionals and surgeons were more aware of risk assessment tools such as BOADICEA than medical oncologists (P < 0.001). Respondents felt that cancer geneticist (84%) and medical oncologists (85%) should be responsible for discussing the potential use of tamoxifen. Medical oncologists were favored over cancer geneticists to initiate prescription (83% vs 56%) and monitor (72% vs 33%) tamoxifen use. Most felt GPs could also monitor (64%).

The most frequently identified barrier to physician prescription was a feeling that it was not their role (50%). Genetic health professionals felt this more than medical oncologists (85% vs 28%). At risk women are being seen at low rates with only 14% of respondents seeing > 100 patients per year. While 75% of respondents were happy to oversee more patients on RRM, only 10% of health professionals were willing to see > 49 additional patients per year indicating a workforce issue.

Conclusions: Despite tamoxifen as an RRM being widely accepted to be effective by health professionals, there are still significant barriers to its prescription including workforce issues.
