Barriers to advance care planning among patients with advanced serious illnesses: A national survey of health-care professionals in Singapore.

To assess the barriers that health-care professionals (HCPs) face in having advance care planning (ACP) conversations with patients suffering from advanced serious illnesses and to provide care consistent with patients' documented preferences. We conducted a national survey of HCPs trained in facilitating ACP conversations in Singapore between June and July 2021. HCPs responded to hypothetical vignettes about a patient with an advanced serious illness and rated the importance of barriers (HCP-, patient-, and caregiver-related) in (i) conducting and documenting ACP conversations and (ii) providing care consistent with documented preferences. Nine hundred eleven HCPs trained in facilitating ACP conversations responded to the survey; 57% of them had not facilitated any in the last 1 year. HCP factors were reported as the topmost barriers to facilitating ACP. These included lack of allocated time to have ACP conversations and ACP facilitation being time-consuming. Patient's refusal to engage in ACP conversations and family experiencing difficulty in accepting patient's poor prognosis were the topmost patient- and caregiver-related factors. Non-physician HCPs were more likely than physicians to report being fearful of upsetting the patient/family and lack of confidence in facilitating ACP conversations. About 70% of the physicians perceived caregiver factors (surrogate wanting a different course of treatment and family caregivers being conflicted about patients' care) as barriers to providing care consistent with preferences. Study findings suggest that ACP conversations be simplified, ACP training framework be improved, awareness regarding ACP among patients, caregivers, and general public be increased, and ACP be made widely accessible.
