About

This evaluation will examine the feasibility, implementation, and effectiveness of a quality improvement intervention-Intensive Management Patient Aligned Care Team (ImPACT)-for high-risk patients.

Full description

Background: VA's highest-utilizing patients generally have complicated health care needs-including complex and multiple chronic conditions, comorbid mental health conditions, and social stressors-that contribute to high rates of hospitalization, emergency services, and specialty care use. Inspired by emerging intensive primary care models for high-utilizers, VA Palo Alto launched a quality improvement program to augment existing VA primary care (provided by Patient Aligned Care Teams, PACT) with intensive care delivered by a multidisciplinary team. The Intensive management PACT (ImPACT) intervention encompasses a number of evidence-based strategies, including a comprehensive intake process, coordination of specialty care, chronic condition case management, provision of social services, rapid response to deteriorations in health, and facilitation of transitions after high-acuity events.

The ImPACT program was designated as quality improvement (non-research) by the Palo Alto VA. A retrospective evaluation using deidentified data was approved by the Stanford University IRB.

Objectives: The objectives of this evaluation are to assess ImPACT's feasibility, implementation, and effectiveness, and lay the groundwork for future larger-scale efforts and evaluations within the VA system.

Methods: We will partner with the implementation team of VA Palo Alto's ImPACT clinic to conduct a Hybrid Type 1 evaluation of the program's feasibility, implementation, and effectiveness. Specifically, the evaluation will aim to:

1. Evaluate the feasibility and implementation of the pilot ImPACT intervention. Using semi-structured interviews with ImPACT and PACT team members and leadership, we will evaluate the success of intervention delivery, including patient identification, recruitment, and retention; provision and uptake of planned services; and monitoring of patient participation and key outcomes.
2. Evaluate ImPACT's effect on utilization and costs of care. We will use a difference-in-differences approach, wherein we compare changes in VA health care costs (total, as well as inpatient, outpatient, and fee-basis) and utilization (including hospitalizations, emergency department visits, and specialty care) among ImPACT patients and high-utilizing patients who are receiving usual PACT care.
3. Examine the association between ImPACT participation and patient-centered outcomes. Using data from surveys administered in the ImPACT clinic, we will assess patient satisfaction with the ImPACT intervention and overall care, as well as changes in patient-reported outcomes, including health status, symptom burden, and function.

583 participants in 2 patient groups

ImPACT

Experimental group

Description:

Patients in ImPACT receive intensive outpatient care from the ImPACT team. The ImPACT team augments existing PACT primary care with intensive services delivered by a multidisciplinary team (including a physician, nurse practitioner, social worker, recreational therapist, and program coordinator). ImPACT program elements include a comprehensive patient assessment, identification and tracking of patients' goals and priorities, care management for medical and social service needs, co-attendance at specialty care appointments, and coordination of care with VA and non-VA providers, including during and after hospitalization.

Treatment:

Other: ImPACT

PACT

No Intervention group

Description:

Patients in PACT receive usual VA primary care through the VA's Patient Centered Medical Home. VA primary care is delivered by PACT teamlets that comprise a primary care provider, nurse, clinical associate, and administrative associate who are supported by social work, pharmacy, and behavioral health services.
