Each year, approximately 3.5 million individuals in the United States experience homelessness (“Hunger and Homelessness,” n.d.). Patients experiencing homelessness have negative health outcomes in part due to decreased access to health care (Fitzpatrick et al., 2011). Additionally, the rate of behavioral health disorders (i.e., mental health and substance use disorders) in patients experiencing homelessness is about 66% (“HCH,” 2006; “National Coalition,” 2014). Follow-up rates for behavioral health services embedded within primary care are higher for transient patient populations when compared to specialty mental health services offered off-site: 16% no-show rate in primary care compared to a 35% no-show rate in specialty mental health settings (Reynolds, Chesney, & Capobianco, 2006). This suggests the need for improved primary care behavioral health integration efforts with this population (Miller et al., 2014; Reynolds et al., 2006). Behavioral health providers have varying roles on the primary care team (Collins et al., 2010; “HCH,” 2006; Heath et al., 2013; Miller-Matero et al., 2014; Robinson & Strosahl, 2009) but the Primary Care Behavioral Health (PCBH) consultation role has not been described with this special population as well as quality improvement efforts with practice change.
