Expanding Access to Home-Based Palliative Care

28 september 2019 bijgewerkt door: Susan Enguidanos, University of Southern California

Expanding Access to Home-Based Palliative Care Through Primary Care Medical Groups

This study will test the effectiveness of integrating an evidence-based model of home-based palliative (HBPC) within primary care clinics on patient and caregiver outcomes. The investigators will conduct a randomized controlled trial, randomizing 1,155 seriously ill patients (and approximately 884 family caregivers) who receive primary care from 30-40 regional accountable care organizations (ACOs) in California to one of two study groups: HBPC or enhanced usual care (EUC). Follow-up data will be collected via telephone surveys with patients at 1- and 2-months and with caregivers at 1- and 2-months, and, as appropriate, following the death of the patient.

Background and Significance

Patients with serious illness from cancer, heart failure (HF), and chronic obstructive pulmonary disease (COPD) often receive poor quality of care, resulting in unmitigated pain and related symptoms, unmet psychosocial needs, and significant caregiver burden. Palliative care, a patient-centered approach that provides pain and symptom management and psychosocial and spiritual support, has strong evidence for improved outcomes for these seriously ill patients. Palliative care differs from hospice in that it is offered early in the illness course and in conjunction with other therapies intended to prolong life. Most palliative care programs are hospital-based; few offer care at home, where patients spend the most time and require the most support.

Study Aims

This study will test the effectiveness of integrating an evidence-based model of home-based palliative (HBPC) within primary care clinics on patient and caregiver outcomes. The investigators will conduct a randomized controlled trial, randomizing 1,155 seriously ill patients (and approximately 884 family caregivers) who receive primary care from 30-40 regional accountable care organizations (ACOs) in California to one of two study groups: HBPC or enhanced usual care (EUC). Follow-up data will be collected via telephone surveys with patients at 1- and 2-months and with caregivers at 1- and 2-months, and, as appropriate, following the death of the patient.

The study's specific aims are:

  • Specific Aim 1: Determine differences in improvement on measures of physical and psychological well-being between patients receiving HBPC and patients receiving enhanced usual care (EUC).
  • Specific Aim 2: Determine differences in survival time between patients receiving HBPC and patients receiving EUC.
  • Specific Aim 3: Determine differences in number of emergency department (ED) visits and hospital admissions between patients receiving HBPC and patients receiving EUC.
  • Specific Aim 4: Determine differences in improvement on patient-provider communication between patients receiving HBPC and patients receiving EUC.
  • Specific Aim 5: Determine differences in improvement on psychosocial outcomes between caregivers of patients receiving HBPC and caregivers of patients receiving EUC.

Study Description

Study Population. The study will enroll 1,155 patients and approximately 883 caregivers from primary care medical groups operating under ACO contracts with Blue Shield of California (Blue Shield), the study's insurance partner. About 75% of patients will be age 65 or older; about 55% will be female. About 45% of patients will be ethnic minority members, predominantly of Hispanic decent.

Comparators. The study will compare outcomes from two groups: patients who receive EUC (with usual care enhanced by: 1) provider training in palliative care; 2) case management for EUC patients; and 3) provider support through palliative care consultation) and patients who receive HBPC provided by an HBPC team. HBPC features home visits by an interdisciplinary PC team (physician, nurse, social worker, and chaplain) that provides pain and symptom management, psychosocial support, advance care planning, disease management education, spiritual and grief counseling, and other services as needed.

Outcomes. Primary outcomes are change in patient pain, symptoms, depression, and anxiety. These measures will be collected via patient self-report at baseline and at one- and two-months following enrollment. Change in survival, ED visits, and hospital episodes (including length of stay, when applicable) also are primary outcomes that will be collected from the electronic medical record (EMR). These data will be collected following patient death or at study's end. Secondary patient outcomes are peace, patient-physician communication, and hope.Secondary caregiver outcomes are change in caregiver depression, anxiety, burden, and patient-physician communication, with these assessments all collected at baseline and one- and two-months following enrollment. Caregiver's experience of patient death will be collected one month following patient death, when applicable.

Analytic Methods. Investigation of the main effect of HBPC and EUC on outcomes will be conducted at each follow-up and then on the longitudinal trend. Baseline outcome measures will be treated as covariates to control for potential baseline differences. Repeated measures analyses will be used to investigate the longitudinal effects of program conditions on outcome measures. Sub-analyses will examine outcome differences by patient age, diagnosis, and race.

Experimenteel: Home-based Palliative Care
Home-based palliative care features home visits by an interdisciplinary PC team (physician, nurse, social worker, and chaplain) that provides pain and symptom management, psychosocial support, advance care planning, disease management education, spiritual and grief counseling, and other services as needed.
Ander: Home-based palliative care
The HBPC model consists of home visits by an interdisciplinary primary palliative care team (a physician, nurse, social worker, and chaplain). This team provides pain and symptom management, psychosocial support, advance care planning, spiritual counseling, grief counseling, and other services to meet patient and caregiver needs. Within the first week of a patient's enrollment, team members separately visit the patient at home to assess his/her needs as well as the needs of his/her caregiver. Following the patient's initial assessment, subsequent home visits are based on the patient's and caregiver's needs. At a minimum, a core team member visits the patient at home once per week. Additionally, a 24/7 helpline provides access to nurse counseling and after-hours home visits as needed. As a patient's health declines and he/she becomes eligible for hospice care, HBPC clinicians will refer the patient to hospice.

  • Home-based primary palliative care
Actieve vergelijker: Enhanced Usual Care
Enhanced usual care refers to: 1) usual primary care provided by a primary care physician who has been offered special training in the core elements of palliative care; 2) case management services; and 3) provider support through palliative care consultation.
Ander: Enhanced usual care

Usual primary care consists of: 1) appointment-based access to primary care providers (PCPs) as requested by the patient; 2) case management services; and 3) provider support through palliative care consultation. These PCPs provide family/internal medicine services as well as access to specialist care. They also offer disease case management and pain and symptom management.

These usual care services are enhanced through training in palliative care provided to PCPs. The training addresses core elements of palliative care, specifically these 6 topics: a palliative care overview; strategies for improving patient-provider communications; instruction in ACP; instruction in managing patients' pain and symptoms; care coordination; and preventing medical crises.
