Association of Palliative Care Consultation in Patients With Heart Failure With Preserved Ejection Fraction With Symptom Burden and Health Care Use.

Background: Guidelines recommend palliative care (PC) for patients with heart failure. However, little research has been performed assessing the effect of PC consultation in patients with heart failure with preserved ejection fraction (HFpEF).

Objectives: The purpose of this study was to investigate the impact of PC consultation on symptom burden and health care utilization among individuals with HFpEF during the last 3 years of their lives.

Methods: We retrospectively analyzed electronic medical records from 72 centers, mainly in the United States. All patients with HFpEF, identified using International Classification of Diseases codes, who died within 3 years of the diagnosis were selected and then stratified based on receipt of PC consultation. Propensity score matching was used to control for between-group differences.

Results: Two hundred twenty-six thousand nine hundred twenty-one patients with HFpEF died within 3 years, only 26.4% of whom received a PC consult. In the unmatched cohort, patients who received a PC consult were more likely to be female, Black, and had more comorbidities. After propensity matching, patients receiving PC consultation were less likely to experience an emergency room visit or hospitalization (2.2% vs 4.6%), surgery or anesthesia (1.1% vs 4.2%), critical care (0.7% vs 1.9%), or receive cardiovascular procedures or tests (1.7% vs 4.7%). Furthermore, they were also less likely to have cardiorespiratory symptoms (2.5% vs 5.7%), heart failure exacerbations (1.6% vs 3.3%), cognitive symptoms (1.7% vs 3.4%), falls (0.3% vs 0.6%), and depression or anxiety (1.3% vs 2.8%).

Conclusions: PC consultation is associated with reduced potential unwanted health care utilization and improvement in symptoms in patients with HFpEF in their last 3 years of life. However, PC continues to be underused in this population.
