IMPACT: Improving Mood — Promoting Access to Collaborative Treatment

The legacy terms “IMPACT Care” or “IMPACT Model” is largely synonymous with Collaborative Care. The terms originate from the IMPACT study, the first large randomized controlled trial of treatment for depression. The IMPACT study demonstrated that Collaborative Care more than doubled the effectiveness of depression treatment for older adults in primary care settings.

The Collaborative Care model (CoCM) is now recognized as effective in treating a wide range of behavioral health disorders – not just depression. A team-based Collaborative Care approach can also address anxiety and trauma disorders, chronic pain, substance use disorders including alcohol and opioids, and ADHD.

In the largest treatment trial for depression to date, a team of researchers led by Dr. Jürgen Unützer followed 1,801 depressed, older adults from 18 diverse primary care clinics across the United States for two years. The 18 participating clinics were associated with eight health care organizations in Washington, California, Texas, Indiana and North Carolina. The clinics included several Health Maintenance Organizations (HMOs), traditional fee-for-service clinics, an Independent Provider Association (IPA), an inner-city public health clinic, and two Veteran’s Administration clinics.

Half of the patients were randomly assigned to receive the care normally available in their primary care clinic, including medications (70% of usual care patients) and/or referral to specialty mental health. The other half of patients were randomly assigned to receive the IMPACT model of depression care, also known as Collaborative Care. A patient registry was developed for the trial that tracked and measured patient goals and clinical outcomes and facilitated treatment adjustment if a patient was not improving as expected.

As reported in JAMA in 2002, Collaborative Care more than doubled the effectiveness of depression treatment for older adults in primary care settings. At 12 months, about half of the patients receiving Collaborative Care reported at least a 50 percent reduction in depressive symptoms, compared with only 19 percent of those in usual care. A handout of usual care versus IMPACT care presents some reasons why the results were as significant as they were. Analysis of data from the survey conducted one year after IMPACT resources were no longer available showed that the benefits of the IMPACT intervention persisted after one year. IMPACT patients experienced more than one hundred additional depression-free days over a two-year period than those treated in usual care.

Since the end of the trial, over one thousand organizations in the United States and internationally have adapted and implemented Collaborative Care with diverse patient populations and for a variety of behavioral health conditions.

Depression Improvement Across Minnesota, Offering a New Direction (DIAMOND)

DIAMOND was a collaborative effort of 9 health plans, 25 medical groups, and over 80 primary care clinics in Minnesota to implement and study Collaborative Care for depression. The AIMS Center provided consultation and coaching for the initiative. In addition, the National Institute of Mental Health (NIMH) awarded a $3 million grant to HealthPartners Research Foundation to study the DIAMOND initiative over five years. The study evaluated all aspects of DIAMOND, including effects of the program on patient satisfaction, productivity, and program cost-effectiveness. The project used a patient registry that tracks and measures patient goals and clinical outcomes, and facilitates treatment adjustment if a patient is not improving as expected.

AARP Program to Improve Depression Care for Older Adults

Jürgen Unützer is consulting to the American Association of Retired Persons (AARP) to help implement and support comprehensive evidence-based depression care management in the context of its Health Improvement Initiatives.

Dulce + IMPACT: Combining depression and diabetes care management

This research project combined IMPACT depression care management with an existing diabetes care management program for low income, predominantly Spanish-speaking Latinx people in San Diego. The study shows that this combined approach is both effective and cost-effective with this population.

Building Collaborative Care in New Orleans

When hurricanes Katrina and Rita devasted New Orleans, the AIMS Center worked on a Red Cross funded initiative to rebuild the primary care system to include Collaborative Care. The project enhanced the availability of evidence-based mental health services to uninsured, disadvantaged, and minority community members offered through REACH NOLA’s Mental Health Infrastructure and Training Project. It also showed the benefits of integrated mental health care after disasters, particularly for depression and post-traumatic stress disorder (PTSD). To our knowledge, the program is the first time that a Collaborative-Care-based quality improvement approach for mental health treatment had been applied in a post-disaster recovery setting.

Whole Person Integrated Texting for Health (WITH)

The number of older adults is rising sharply and is expected to increase from 40.3 million to 72.1 million between 2010 and 2030. According to the Pew Research Center, 92% of adults aged 65 and older use text messaging. Despite misconceptions to the contrary, text messaging as part of primary care for older adults is growing. Text messaging holds promise as a strategy for engaging older adults in Collaborative Care depression treatment through frequent contact with a behavioral health care manager. The purpose of this research project is to develop and pilot test a text messaging intervention delivered in California primary care settings serving a patient population that is at least 25% older adults. Published research (Bao et. al. 2015) demonstrated that early follow-up contact predicts better clinical outcomes for patients. A recent analysis published by the AIMS Center (Renn et. al. 2021) showed that Collaborative Care was equally effective in older and younger adults but that older adults needed more contact with the behavioral health care manager to achieve these equivalent outcomes. Text messaging may be an effective strategy for both early and more frequent contact with patients. The AIMS Center is partnering with the Archstone Foundation on this project.

Care Partners: Bridging Families, Clinics, and Communities to Advance Late-Life Depression Care

Through Archstone Foundation’s Depression in Late Life Initiative, the Care Partners project seeks to improve depression care for older adults by building innovative and effective community partnerships. Specifically, the Care Partners project has the following goals: 1) develop late-life depression innovations among primary care, community-based organizations (CBOs) and family, 2) build a learning community of clinics, CBOs, and researchers in California who will work together on the Care Partners Late-Life Depression Initiative to improve care for depressed older adults, 3) conduct an evaluation of the developing models, and 4) develop and conduct a Learning Collaborative in Year 5 for California clinics and CBOs interested in improving depression care for older adults. Throughout the project, project teams at the University of Washington (UW) and UC-Davis (UCD) provide technical assistance and evaluation to support site development and sustainment. Together, the community-engaged partnerships have tremendous potential to improve access to care, patient engagement, patient care experience and quality of care. In addition, CBO and clinic partners are well primed to improve care through addressing the social determinants of health.
