AimTo determine the cultural competency training, knowledge and attitudes of health professionals about Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) health‐care delivery.MethodsSurvey of medical (n = 200), nursing (n = 200) and other health professionals (n = 210) working in two tertiary paediatric hospitals in December 2013. The main outcome measures were training in Aboriginal health‐care delivery, knowledge of Aboriginal health and services, attitudes to identification of Aboriginal patients and suggested ways to improve health‐care delivery to Aboriginal patients.ResultsWe received responses from 286 of 572 (50.0%) staff with valid emails: 75 medical, 88 nursing and 123 other health professionals. A minority reported receiving specific Aboriginal health training (126/286, 44.8%) and Aboriginal cultural competency training (106/286, 37.1%). Medical staff were less likely than others to report Aboriginal health‐care training (P = 0.01), cultural competency training (P < 0.001) and that their training equipped them to manage Aboriginal patients (P = 0.04). Few medical staff reported a good/very good knowledge of the services provided by the Aboriginal Community Controlled Health Services (20.0%), the Federal Government Closing the Gap initiative (14.7%) or the Royal Australasian College of Physicians' Reconciliation Action Plan (8.0%). Only 62 of 286 (21.7%) staff agreed that they usually asked patients/parents whether they identified as Aboriginal. Although 256 of 286 (89.5%) agreed that Aboriginal staff were an important resource, only 125 of 286 (43.7%) had referred Aboriginal patients to one.ConclusionThe opportunities we have identified to improve health‐care delivery to Aboriginal patients include: increasing Aboriginal cultural competency training, correct identification of Aboriginal patients, referring Aboriginal patients to Aboriginal health‐care services and increased awareness of Aboriginal Community Controlled Health Services.
