Doctors' perspectives on adhering to advance care directives when making medical decisions for patients: an Australian interview study.

ACDs provide doctors with opportunities to align patient preferences with treatment and uphold patient autonomy. However, doctors experience decisional conflict when attempting to adhere to ACDs in practice, especially when they believe that adhering to the ACD is not in the patients' best interests, or if they doubt the validity of the ACD. Future ACP programmes should consider approaches to improve the validity and applicability of ACDs. In addition, there is a need for ethical and legal education to support doctors' knowledge and confidence in ACP and enacting ACDs.
