Background: In response to a growing need for accessible, efficient, and effective palliative care services, we designed, implemented, and evaluated a novel palliative care at home (PC@H) model for people with serious illness that is centered around a community health worker, a registered nurse, and a social worker, with an advanced practice nurse and a physician for support. Our objectives were to measure the impact of receipt of PC@H on patient symptoms, quality of life, and healthcare utilization and costs.

Methods: We enrolled 136 patients with serious illness in this parallel, randomized controlled trial.

Article Synopsis
  • - The study investigates the use of hospice aide care in various residential settings (community, assisted living, nursing homes) among Medicare beneficiaries who died between 2010 and 2019.
  • - Findings reveal that hospice aide visits were least frequent in community settings (64.4%) compared to assisted living (76.6%) and nursing homes (72.6%).
  • - Although hospice aides provide essential care, the reasons for their use did not significantly differ by setting, indicating a need for better understanding of how to optimize hospice care across different types of residences.

Policy makers in the US are increasingly concerned that greater use of the Medicare hospice benefit by people with dementia is driving up costs. Yet this perspective fails to incorporate potential cost savings associated with hospice. We estimated the association between hospice use by people with dementia and health care costs, using Medicare Current Beneficiary Survey data from the period 2002-19.

Many studies have examined factors associated with individuals of high or low healthcare spending in a given year. However, few have studied how healthcare spending changes over multiple years and which factors are associated with the changes. In this study, we examined the dynamic patterns of healthcare spending over a three-year period, among a nationally representative cohort of Medicare beneficiaries in the U.

Context: Although palliative care is guideline-indicated for patients with advanced heart failure (HF), the scarcity of a specialty-trained palliative care workforce demands better identification of patients who are most burdened by the disease.

Objectives: We sought to identify latent subgroups with variations regarding symptom burden, functional status, and multimorbidity in an advanced HF population.

Methods: We performed a latent class analysis (LCA) of baseline data from a trial enrolling advanced HF patients.

Importance: Use of hospice has been demonstrated to be cost saving to the Medicare program and yet the extent to which hospice saves money across all payers, including whether it shifts costs to families, is unknown.

Objective: To estimate the association between hospice use and total health care costs including family out-of-pocket health care spending.

Design Setting And Participants: This retrospective cohort study of health care spending in the last 6 months of life used data from the nationally representative Medicare Current Beneficiary Survey (MCBS) between the years 2002 and 2018.

Background: To identify and rank the importance of key determinants of end-of-life (EOL) health care costs, and to understand how the key factors impact different percentiles of the distribution of health care costs.

Method: We applied a principled, machine learning-based variable selection algorithm, using Quantile Regression Forests, to identify key determinants for predicting the 10th (low), 50th (median), and 90th (high) quantiles of EOL health care costs, including costs paid for by Medicare, Medicaid, Medicare Health Maintenance Organizations (HMOs), private HMOs, and patient's out-of-pocket expenditures.

Results: Our sample included 7 539 Medicare beneficiaries who died between 2002 and 2017.

Importance: Despite efforts to enhance serious illness communication, patients with advanced heart failure (HF) lack prognostic understanding.

Objectives: To determine rate of concordance between HF patients' estimation of their prognosis and their physician's estimate of the patient's prognosis, and to compare patient characteristics associated with concordance.

Design: Cross-sectional analysis of a cluster randomized controlled trial with 24-month follow-up and analysis completed on 09/01/2020.

Background: Prognostic awareness (PA)-the understanding of limited life expectancy-is critical for effective goals of care discussions (GOCD) in which patients discuss their goals and values in the context of their illness. Yet little is known about PA and GOCD in patients with advanced heart failure (HF). This study aims to determine the prevalence of PA among patients with advanced HF and patient characteristics associated with PA and GOCD.

Implantable cardioverter-defibrillators (ICDs) reduce the incidence of sudden cardiac death for high-risk patients with heart failure (HF), but shocks from these devices can also cause pain and anxiety at the end of life. Although professional society recommendations encourage proactive discussions about ICD deactivation, clinicians lack training in conducting these conversations, and they occur infrequently. As part of a six-center randomized controlled trial, we evaluated the educational component of a multicomponent intervention shown to increase conversations about ICD deactivation by clinicians who care for a subset of patients with advanced HF.

Background/objectives: The Medicare Advantage (MA) program insures a rapidly growing proportion of older adults, and may be more appealing due to lower cost sharing. However, the extent to which older adults are informed of their plan benefits and how plan knowledge has changed over time is unclear. We evaluated temporal trends and characteristics associated with not knowing MA coverage for dental, vision, and nursing home (NH) services.

Background: Although implantable cardioverter-defibrillators (ICDs) reduce sudden death, these patients die of heart failure (HF) or other diseases. To prevent shocks at the end of life, clinicians should discuss deactivating the defibrillation function.

Objectives: The purpose of this study was to determine if a clinician-centered teaching intervention and automatic reminders increased ICD deactivation discussions and increased device deactivation.

Background: Early integration of palliative care into the management of patients with serious disease has the potential to both improve quality of life of patients and families and reduce healthcare costs. Despite these benefits, significant barriers exist in the United States to the early integration of palliative care in the disease trajectory of individuals with serious illness.

Aim: To provide an overview of the barriers to more widespread palliative care integration in the United States.

Objectives: Despite evidence that treatment is effective in reducing recidivism among inmates with substance use problems, scarce resources mean that few of those in need of treatment actually receive it. Computerized substance abuse interventions could be used to expand access to treatment in prisons without placing an undue burden on resources. The major aim of the study was to compare treatment conditions in terms of their service utilization, skills acquisition, and treatment satisfaction.
