The United States is facing an ongoing mental health and substance use crisis. In 2023, 58.7 million US adults had a past-year mental illness, 46.3 million had a substance use disorder (SUD), and 20.4 million had both.1 Overdose and suicide deaths have risen substantially over the past decades,2-6 contributing to declining life expectancy that is unevenly distributed across sociodemographic subgroups.7 In addition to their impact on premature mortality, mental illness and SUD are primary contributors to acute and chronic morbidity and disability.8 Still, only half of people with a mental illness and a quarter with SUD in the United States received any treatment for these conditions in 2023.1
Despite gaps in access to behavioral health treatment, people with mental illness and SUD interact with general health care settings for a range of needs. Two critical points of care are primary and emergency care settings. Primary care is often the first or sole point of contact for most of the population, playing an increasingly significant role in identification, treatment, and referral to other specialties or levels of care for behavioral health conditions.9, 10 Indeed, over a third of visits for any mental illness in the United States occur in primary care settings.11 At the other end of the spectrum, emergency departments (EDs) and hospitals bear the charge of addressing severe behavioral health needs, particularly in the aftermath of the COVID-19 pandemic.12-16 Of all ED encounters between 2018 and 2020, 12% were for behavioral health conditions.15
