Brief ReportPolypharmacy in Palliative Care for Advanced Heart Failure: The PAL-HF Experience
Section snippets
Methods
The PAL-HF trial is a previously reported randomized controlled trial designed to test the efficacy of a multidisciplinary PC intervention on QOL in patients with advanced HF.6 The study protocol was approved by the institutional review board, and all participants gave informed consent. Patients admitted to a single center with a primary diagnosis of acute decompensated HF with advanced disease were randomized to standard care (n = 75) vs standard care and an interdisciplinary PC intervention (n
Results
The median age of the patients was 72 (interquartile range 62–80) years, 47% were female, and 41% were Black. Overall, 48% had an ischemic etiology, and 55% had an ejection fraction 40% or less.
At 2 weeks after hospital discharge, the mean count for HF medications in the intervention arm was 6.7 ± 5.2 vs 6.5 ± 5.0 in the control arm (P = .84), and the mean count for PC medications was 3.6 ± 3.4 vs 3.0 ± 2.9 (P = .25), respectively. At 6 months, the mean count for HF medications in the
Discussion
In the PAL-HF trial, polypharmacy as defined by the World Health Organization was universal, and the number of prescribed medications actually increased over time. Importantly, this result occurred in the context of improved patient-reported QOL among those in the intervention arm.6
Historically, PC studies have found that achieving the key goals of PC, such as ameliorating symptoms, decreasing the frequency of symptom exacerbations, and improving comfort, often necessitates a burgeoning number
Limitations
Several caveats should be considered in interpreting the results presented in this report. First, the sample size was relatively small, and patients were enrolled at a single academic center. Second, the duration of follow-up was short, and longer term follow-up of the patterns of medication use in these patients remains undefined. Third, we do not know how much selection for PAL-HF enrollment affected the patterns of medication use relative to comparably ill advanced HF patients not considered
Conclusions
Polypharmacy was universal at enrollment into the PAL-HF trial and the number of medications prescribed increased in both the PAL-HF intervention and standard care groups over time. Optimizing medications for symptom management regardless of medication count, known as appropriate polypharmacy, may be an important component in interventions to improve QOL for patients with advanced HF.
Patient Significance
- •
Palliative care aims to improve symptoms and quality of life for people with serious illness, including advanced heart failure.
- •
Palliative care helps patients manage symptoms in part through medications, which may increase the total number of medications prescribed.
- •
This study showed that, despite increasing medications, the palliative care intervention improved symptoms and quality of life in people participating in the intervention, which may be beneficial for patients with advanced heart
Lay Summary
Palliative care aims to improve symptoms and quality of life for people with serious illness. In advanced heart failure, palliative care helps patients to manage their symptoms in part through medications, which may increase the total number of medications prescribed. This is known as polypharmacy (>5 medications). The effects of polypharmacy on patient outcomes in advanced heart failure are unknown. This study showed that the number of medications prescribed in the PAL-HF trial increased in
Funding
The PAL-HF study was funded by the National Institute of Nursing Research (NINR: R01NR013428) from the National Institutes of Health under randomized controlled trial no. NCT01589601.
