The self-perceived palliative care barriers and educational needs of clinicians working in hospital primary care teams and referral patterns: lessons learned from a single-center survey and cohort study.

Background: Within the generalist-plus-specialist palliative care model, palliative care is mainly provided by nurses and physicians of hospital primary care teams. Palliative care consultation teams (PCCTs) support these clinicians in adequately caring for patients with advanced illnesses. Our team started in 2012. The aim of this study was to assess the self-perceived barriers, educational needs and awareness of available palliative care support options among our hospital primary care teams. In addition, palliative care referral patterns were evaluated.

Methods: Single-center mixed methods study. Outcomes of two surveys of primary care team clinicians (2012 and 2016) on barriers to palliative care, educational needs and awareness of palliative care support options were compared (chi-square, Mann-Whitney U tests, qualitative analysis). Palliative care referral characteristics were evaluated (2012-2017), including referral timing (survival since referral) (descriptive statistics, Kaplan-Meier methodology). Predictions of survival at referral were analyzed (weighted Kappa).

Results: In 2012 and 2016, the most frequently reported barrier was the late initiation of the palliative care approach. Clinicians reported a need for education on physical symptom management and basic palliative care principles. Awareness of support options increased from 2012 to 2016, including improved familiarity with the PCCT (56% vs. 85%, P<0.001) and positive appraisal of the team (8% vs. 40% gave an 'excellent' rating, P<0.001). The use of national symptom management guidelines also improved (23% vs. 53%, P<0.001). Of 1,404 referrals, 86% were for cancer patients. Referrals increased by 28% (mean) per year. Medical oncology clinicians referred most frequently (27%) and increasingly early in the disease trajectory (survival ≥3 months after referral) (P=0.016). Median survival after referral was 0.9 (range, 0-83.3) months. Referring physicians overestimated survival in 44% of patients (kappa 0.36, 95% CI: 0.30-0.42).

Conclusions: Primary care team clinicians persistently reported needing support with basic palliative care skills. PCCTs should continuously focus on educating primary care teams and promoting the use of guidelines. Because physicians tend to overestimate survival and usually referred patients late for specialist palliative care, consultation teams should support primary care teams to identify, treat and refer patients with palliative care needs in a timely manner.
