BackgroundICU patients and their families experience significant stress due to illness severity and prognostic uncertainty, making palliative care (PC) integral for symptom management, family support, and end-of-life care goals. The impact of PC in the Cardiac Intensive Care Unit (CICU) remains unstudied. ObjectiveWe explore the impact of early palliative care consultation (PCC) on patient outcomes in the CICU, including mortality, length of stay, and family meeting frequency. MethodsThis retrospective study at MedStar Washington Hospital Center included 209 adult patients admitted to the CICU between December 2021 and June 2022 receiving PCC. We compared outcomes between those receiving early (<72 h) and late (>72 h) PCC, including mortality, length of stay, and family meeting frequency. Statistical analysis included Wilcoxon rank sum tests, Chi-squared tests, Fisher's exact test, and Poisson regression models. ResultsThe study included 209 patients admitted to the (M age = 68 years, SD = 14; 45 % female; 62 % Black, 30 % White) who received PCC, most (79 %) within 72 h. Early PCC was associated with shorter CICU stays (median, 3 vs. 5.5 days; p = 0.005). Early PCC patients had higher odds of family meetings (IRR=3.59; p < 0.001) and experienced a change in code status sooner (median 1 day vs. 3 days, p < 0.001). Late PCC patients were more likely to undergo tracheostomy (13.6% vs. 2.4 %; p = 0.007), cardioversion (9.1% vs. 1.8 %; p = 0.037), and have PEG tubes placed (13.6% vs. 2.4 %; p = 0.007). ConclusionsEarly PCC in the CICU is associated with shorter CICU stays, fewer procedures, and more frequent family meetings.
