To assess the impact of early triggered palliative care consultation on the outcomes of high risk ICU patients.
Patients ( n=199) admitted to the medical ICUs from August 2017 to May 2018 with a positive palliative care screen indicating high risk for morbidity or mortality.
The medical ICUs were randomized to intervention or usual care followed by washout and crossover, with independent assignment of patients to each ICU on admission. Intervention arm patients received a palliative care consultation from an interprofessional team led by board-certified palliative care providers within 48 hours of ICU admission.
97 patients (48.7%) were assigned to the intervention and 102 (51.3%) to usual care. Transition to do-not-resuscitate/do-not-intubate (DNR/DNI) occurred earlier and significantly more often in the intervention group than the control group (50.5% vs 23.4%, p<0.0001). The intervention group had significantly more transfers to hospice care (18.6% vs 4.9%; p<0.01) with fewer ventilator days (median 4 vs 6 days; p<0.05), tracheostomies performed (1% vs 7.8%; p<0.05), and post-discharge emergency department visits and/or readmissions (17.3% vs 38.9%; p<0.01). While total operating cost was not significantly different, medical ICU ( p<0.01) and pharmacy ( p<0.05) operating costs were significantly lower in the intervention group. There was no significant difference in ICU length of stay (median 5 vs 5.5 days), hospital length of stay (median 10 vs 11 days), in-hospital mortality (22.6% vs 29.4%), or 30-day mortality between groups (35.1% vs 36.3%) ( p values>0.05).
Early triggered palliative care consultation was associated with greater transition to DNR/DNI and to hospice care, as well as decreased ICU and post-ICU healthcare resource utilization. Our study suggests that routine palliative care consultation may positively impact the care of high risk, critically ill patients.
