Trends and Predictors of Palliative Care Consultation Among Patients Admitted for LVAD: A Retrospective Analysis From the Nationwide Inpatient Sample Database From 2006-2014.

BACKGROUND

Left ventricular assist devices (LVADs) are an essential part of advanced heart failure (HF) management, either as a bridge to transplantation or destination therapy. Patients with advanced HF have a poor prognosis and may benefit from palliative care consultation (PCC). However, there is scarce data regarding the trends and predictors of PCC among patients undergoing LVAD implantation.

AIM

This study aims to assess the incidence, trends, and predictors of PCC in LVAD recipients using the United States Nationwide Inpatient Sample (NIS) database from 2006 until 2014.

METHODS

We conducted a weighted analysis on LVAD recipients during their index hospitalization. We compared those who had PCC with those who did not. We examined the trend in palliative care utilization and calculated adjusted odds ratios (aOR) to identify demographic, social, and hospital characteristics associated with PCC using multivariable logistic regression analysis.

RESULTS

We identified 20,675 admissions who had LVAD implantation, and of them 4% had PCC. PCC yearly rate increased from 0.6% to 7.2% (P < 0.001). DNR status (aOR 28.30), female sex (aOR 1.41), metastatic cancer (aOR: 3.53), Midwest location (aOR 1.33), and small-sized hospitals (aOR 2.52) were positive predictors for PCC along with in-hospital complications. Differently, Black (aOR 0.43) and Hispanic patients (aOR 0.25) were less likely to receive PCC.

CONCLUSION

There was an increasing trend for in-hospital PCC referral in LVAD admissions while the overall rate remained low. These findings suggest that integrative models to involve PCC early in advanced HF patients are needed to increase its generalized utilization.
