Association between the Availability of Hospital-Based Palliative Care and Treatment Intensity for Critically Ill Patients

Rationale: In the intensive care unit (ICU), studies involving specialized palliative care services have shown decreases in the use of non-beneficial life-sustaining therapies and ICU length of stay for patients. However, whether widespread availability of hospital-based palliative care is associated with less frequent use of high intensity care is unknown. Objective: To determine whether availability of hospital-based palliative care is associated with decreased markers of treatment intensity for ICU patients. Methods: Retrospective cohort study of adult ICU patients in New York State hospitals, 2008-2014. Multilevel regression was used to assess the relationship between availability of hospital-based palliative care during the year of admission and hospital length of stay, use of mechanical ventilation, dialysis and artificial nutrition, placement of a tracheostomy or gastrostomy tube, days in ICU and discharge to hospice. Results: Of 1,025,503 ICU patients in 151 hospitals, 814,794 (79.5%) received care in a hospital with a palliative care program. Hospital length of stay was similar for patients in hospitals with and without palliative care programs (6 days, interquartile range (IQR) 3-12 vs. 6 days, IQR 3-11, adjusted rate ratio 1.04 [1.03 to 1.05], p < 0.001), as were other healthcare utilization outcomes. However, patients in hospitals with palliative care programs were 46% more likely to be discharged to hospice than those in hospitals without palliative care programs (1.7% vs. 1.4%, adjusted odds ratio 1.46 [1.30 to 1.64], p
