Referral Practices of Cardiologists to Specialist Palliative Care in Canada

Patients with heart failure have palliative care needs that can be effectively addressed by specialist palliative care (SPC). Despite this, SPC utilization by this patient population is low, suggesting barriers to SPC referral. We sought to determine the referral practices of cardiologists to SPC.

Cardiologists across Canada were invited to participate in a survey about their referral practices to SPC. Associations between referral practices and demographic, professional, and attitudinal factors were analyzed using multiple and logistic regression.

The response rate was 51% (551 of 1082). Between 35.1% and 64.2% of respondents were unaware of referral criteria to local SPC services. Of the respondents, 29% delayed SPC referral because of prognostic uncertainty, and 46.8% believed that SPC prioritizes patients with cancer. In actual practice, nearly three-fourths of cardiologists referred late. Referral frequency was associated with greater availability of SPC services for patients with nonmalignant diseases (P = 0.008), a higher number of palliative care settings accepting patients receiving continuous infusions or pursuing acute care management (P < 0.001), satisfaction with services (P < 0.001), and less equation of palliative care with end-of-life care (P < 0.001). Early timing of referral was associated with greater availability of SPC services for patients with nonmalignant diseases and less equation of palliative care with end-of-life care.

The findings suggest that barriers to timely SPC referral include an insufficiency of services for patients with nonmalignant diseases especially in the outpatient setting, the perception that SPC services do not accept patients receiving cardiology-specific treatments, and a misperception about the identity of palliative care.
