Palliative Care Consultation in the Intensive Care Unit Reduces Hospital Costs: A Cost-Analysis

Abstract

Background Palliative care aims to improve or maintain quality of life for patients with life-limiting or life-threatening diseases. Limited research shows that palliative care is associated with reduced intensive care unit length of stay and use of high-cost resources. Methods This was an observational, non-experimental comparison group study on all patients 18 years or older admitted to any intensive care unit (ICU) at Memorial Hermann – Texas Medical Center for 7 to 30 days from August 2013 to December 2015. Length of stay (LOS) and hospital costs were compared between the treatment group of patients with palliative care in the ICU and the control group of patients with usual care in the ICU. To adjust for confounding of the palliative care consultation on LOS and hospital cost, an inverse probability of treatment weighted method was conducted. Generalized linear models using gamma distribution and log link were estimated. All costs were converted to 2015 US dollars. Results Mean LOS was 13 days and mean total hospital costs were USD 58,378. In adjusted and weighted analysis, LOS for the treatment group was 8% longer compared to the control group. The mean total hospital cost was estimated to decrease by 21% for the treatment group versus the control group. We found a reduction of USD 33,783 in hospital costs per patient who died in the hospital and reduction of USD 9113 per patient discharged alive. Conclusion Palliative care consultation was associated with a reduction in the total cost of hospital care for patients with life-limiting or life-threatening diseases.
