Emergency Department Admission Triggers for Palliative Consultation May Decrease Length of Stay and Costs.

Emergency department (ED) initiated palliative consultation impacts downstream care utilization. Various admission consult triggers have been proposed without clear best practice or outcomes. This 18-month single-center study evaluated the clinical, operational, and financial impact of simplified admission triggers for ED-initiated palliative consults as compared to downstream Floor and intensive care unit (ICU) palliative consults initiated per usual practice. We distilled ED admission triggers into three criteria to ensure bedside actionability and sustainability: (1) end-stage illness, (2) functional limitation, and (3) clinician would not be surprised if the patient died this hospitalization. Eligible patients met all criteria, and received consultation within 24 hours of admission. We compared ED-initiated consults against Floor and ICU consults from March 1, 2018, to September 30, 2019, with matched cohort analysis to evaluate financial outcomes. While overall palliative consult volume remained intentionally steady, the proportion of ED-initiated consults significantly increased (7% vs. 19%,  < 0.001). ED consistently comprised 15-25% of all monthly palliative consults. Compared with Floor, ED had similar ED length of stay (LOS) and inpatient mortality. Among live discharges, ED were more likely to be referred to hospice than Floor (59% vs. 47%,  = 0.24) or ICU (59% vs. 34%,  = 0.02). In a matched cohort analysis, ED demonstrated median cost avoidance of $9,082 per patient versus Floor ($5,578 vs. $14,660,  < 0.001) and $15,138 per patient versus ICU ($5,578 vs. $20,716,  < 0.001). ED had significantly shorter median LOS before consult than Floor (0 vs. 3 days,  < 0.001) or ICU (0 vs. 3 days,  < 0.001), which did not differ between live discharges or inpatient deaths. Overall hospital LOS was disproportionately shorter for ED, with a net difference-in-differences of 1-3.5 days compared to Floor and ICU. Simple ED admission triggers to expedite palliative engagement are associated with a 50-75% reduction in both hospital LOS and costs when compared against usual palliative consultation practice. ED initiation reduces both lead time before consultation and subsequent downstream hospitalization length.
