Abstract

BACKGROUND: The goal of this systematic literature review was to enhance understanding of substance use, service use, and treatment among Latino subgroups to improve access to care and treatment outcomes in an era of health care reform. METHODS: The authors used 13 electronic databases and manually searched the literature from January 1, 1978, to May 30, 2013. One hundred (69%) of 145 primary research articles met the inclusion criteria. Two blinded, independent reviewers scored each article. Consensus discussions and a content expert reconciled discrepancies. RESULTS: Current rates of alcohol and substance abuse among Latinos are comparable to or surpass other U.S. ethnic groups. Disparities in access and quality of care are evident between Latinos and other ethnic groups. As a heterogeneous group, Latinos vary by geographic region in terms of substance of choice and their cultural identity takes precedence over general ethnic identity as a likely determinant of substance abuse behaviors. There is growing research interest in systems influencing treatment access and adherence among racial/ethnic and gender minority groups. However, studies on Latinos' service use and immediate treatment outcomes have been both limited in number and inconsistent in findings. CONCLUSIONS: This review identified human capital, quality of care, and access to culturally responsive care as key strategies to eliminate disparities in health and treatment quality. Implications are discussed, including the need for effectiveness studies on Latinos served by systems of care that, under health care reform, are seeking to maximize resources, improve outcomes, and reduce variation in quality of care.
