Abstract
For almost five decades, the development and implementation of integrated care—the simultaneous combination of primary care with mental health and substance use care—has been a major challenge for the behavioral health care field. Integrated care is exceptionally important because many people with behavioral health conditions also have chronic physical health conditions. Early research findings in the mid-1980s showed that persons with mental illness are likely to develop chronic physical conditions earlier and more severely than other people. These findings precipitated efforts to understand this problem and to develop further appropriate integrated care solutions. Subsequently, the US Surgeon General made care integration a major focus of his landmark 1999 Report on Mental Health, as did the 2008 Mental Health Parity and Addiction Equity Act and the 2010 Patient Protection and Affordable Care Act. However, it was not until 2014, and later, that integrated care actually began to be implemented more broadly. This article reviews these major developmental milestones, examines current activities, and explores likely developments over the next several years. Major current issues include the response to the COVID-19 pandemic, adjusting to its effects on the behavioral health care workforce, and the growing realization that behavioral health care must address the social determinants of life. Likely developments over the next several years will include devising ways to address our workforce crisis, developing effective community interventions, and implementing population health management strategies; implementing the CMS Innovation in Behavioral Health Model; improving reimbursement practices; and exploring the potential of AI for integrated care. Implications for future service organization and training of behavioral health care providers also are discussed. Granted the severity of the current workforce crisis in behavioral health care, urgent efforts are needed to advance the deployment of integrated care in the short-term future.
