Top Ten Tips Palliative Care Clinicians Should Know About Prognostication in Critical Illness and Heart, Kidney, and Liver Diseases

The Impact of Palliative Care Consultation on Aggressive Medical Interventions in End-of-life Among Patients with Metastatic Breast Cancer: Insights from the U.S. National Patient Sample

BACKGROUND

Advancement in treatment has led to prolonged survival and a rising number of women living with metastatic breast cancer (MBC) in the United States. Due to its high symptom burden, it is recommended that palliative care be integrated into the standard care to help improve quality of life. However, little is known about the use of palliative care among MBC patients in the nation.

OBJECTIVES

To determine utilization of palliative care consult (PCC) after metastasis and the influence of PCC on healthcare utilization in the end of life among women living with MBC in the US.

METHODS

This retrospective cohort study examined a national electronic health record database to quantify the PCC use after metastasis diagnosis until death and the associations of PCC with Emergency Department (ED), Intensive Care Unit (ICU), and chemotherapies in the end-of-life women (age ≥ 18 years) living with MBC.

RESULTS

From a cohort of 2615 deceased MBC patients, 37% received PCC in the last 6 months of life. Patients who had received PCC in the end-of-life were more likely to be hospitalized, admitted to ED and ICU, and receive chemotherapies in the last 60 days before death. However, patients who had received end-of-life PCC had less hospital and ED visits and received less chemotherapies after PCC initiated.

CONCLUSION

While PCC can reduce end-of-life aggressive interventions, it was underutilized among patients with MBC in the end-of-life. A myriad of clinical and patient factors may still challenge timely consultation. We urge for future endeavors in developing strategies to remove barriers in the implementation, especially earlier in the disease course, to assure timely PC treatments and reduce discomfort amid aggressive interventions for MBC.
