Early Palliative Care Consultation in the Medical ICU: A Cluster Randomized Crossover Trial.

Abstract

OBJECTIVES\nTo assess the impact of early triggered palliative care consultation on the outcomes of high-risk ICU patients.\n\n\nDESIGN\nSingle-center cluster randomized crossover trial.\n\n\nSETTING\nTwo medical ICUs at Barnes Jewish Hospital.\n\n\nPATIENTS\nPatients (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.\n\n\nINTERVENTIONS\nThe medical ICUs were randomized to intervention or usual care followed by washout and crossover, with independent assignment of patients to each ICU at 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.\n\n\nMEASUREMENTS AND MAIN RESULTS\nNinety-seven patients (48.7%) were assigned to the intervention and 102 (51.3%) to usual care. Transition to do-not-resuscitate/do-not-intubate 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 d; p < 0.05), tracheostomies performed (1% vs 7.8%; p < 0.05), and postdischarge emergency department visits and/or readmissions (17.3% vs 38.9%; p < 0.01). Although 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 d), hospital length of stay (median 10 vs 11 d), in-hospital mortality (22.6% vs 29.4%), or 30-day mortality between groups (35.1% vs 36.3%) (p > 0.05).\n\n\nCONCLUSIONS\nEarly triggered palliative care consultation was associated with greater transition to do-not-resuscitate/do-not-intubate 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.
