We have an innovation that is showing tremendous gains in improving health, especially among vulnerable populations. It has produced a return on investment of 4:1 when applied to children with asthma and a return on investment of 3:1 for Medicaid enrollees with unmet longterm care needs (Felix et al., 2011). Among participating patients with HIV, 60 percent achieve undetectable viral loads (Behforouz, 2014). In fact, examples keep emerging from around the country about its effectiveness in improving health outcomes and reducing emergency room visits and hospitalizations (CHWA, 2013; CDC, 2011; ICER, 2013). If these were the results of a clinical trial for a drug, we would likely see pressure for fast tracking through the FDA; if it was a medical device or a new technology, there would be intense jockeying from a range of start-ups to bring it to market. Instead, despite the promise this innovation has shown for years-and recognition from the Institute of Medicine (IOM, 2010), the Affordable Care Act, and the Department of Laborit still has not been widely replicated or brought into the mainstream of U.S. health care delivery. It is still not supported by most health care financing mechanisms, which causes some organizations that successfully deploy the innovation-and show better health outcomes-to actually lose money (Paquette, 2014). The innovation is the use of community health workers (CHWs), and, more specifically, their integration into team-based primary care. Scaling up the use of CHWs presents a unique set of obstacles, but it is also possible to chart a roadmap forward. The potential to improve care for vulnerable populations, help achieve the Triple Aim of better care, better health and lower costs, and advance population health is too promising to be deterred.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
