Evaluation of Intensive Management Patient Aligned Care Team

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:

• 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.
• 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.
• 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.

Inclusion criteria

• Patient receives care from one of 14 primary care providers (MDs, NPs) who have at least three half-days of clinic per week
• Total VA healthcare costs in the top 5% for VA Palo Alto facility during the 9-month eligibility phase (10/1/11-6/30/12) AND/OR
• Risk for one-year hospitalization in November 2012 in the top 5% (using the VA's Care Assessment Need risk-prediction algorithm)

Exclusion criteria

• Enrollment in VA's mental health intensive case management program, home-based primary care, or palliative care programs
• Recipient of inpatient care for over half of the 9-month eligibility phase (10/1/11-6/30/12).
• Total VA healthcare costs in the lowest cost decile in the 9-month eligibility phase (10/1/11-6/30/12)
• Risk for one-year hospitalization in November 2012 in the lowest risk quartile (using the VA's Care Assessment Need risk-prediction algorithm).
