Thirty years of disparities intervention research: what are we doing to close racial and ethnic gaps in health care?

BACKGROUND: A systematic scan of the disparities intervention literature will allow researchers, providers, and policymakers to understand which interventions are being evaluated to improve minority health and which areas require further research. METHODS: We systematically categorized 391 disparities intervention articles published between 1979 and 2011, covering 11 diseases. We developed a taxonomy of disparities interventions using qualitative theme analysis. We identified the tactic, or what was done to intervene; the strategy, or a group of tactics with common characteristics; and the level, or who was targeted by the effort. RESULTS: The taxonomy included 44 tactics, 9 strategies, and 6 levels. Delivering education and training was the most common strategy (37%). Within education and training, the most common tactics were education about disease (14%) and self-management (11%), whereas communication skills training (3%) and decision-making aids (1%) were less frequent. The strategy of actively engaging the community through tactics such as community health workers and outreach efforts accounted for 6.5% of tactics. Interventions most commonly targeted patients (50%) and community members who were not established patients of the intervening organization (32%). Interventions targeting providers (7%), the microsystem (immediate care team) (9%), organizations (3%), and policies (0.1%) were less common. CONCLUSIONS: Disparities researchers have predominantly focused on the patient as the target for change; future research should also investigate how to improve the system that serves minority patients. Areas for further study include interventions that engage the community, educational interventions that address communication barriers, and the impact of policy reform on disparities in care.

A roadmap and best practices for organizations to reduce racial and ethnic disparities in health care.

Over the past decade, researchers have shifted their focus from documenting health care disparities to identifying solutions to close the gap in care. Finding Answers: Disparities Research for Change, a national program of the Robert Wood Johnson Foundation, is charged with identifying promising interventions to reduce disparities. Based on our work conducting systematic reviews of the literature, evaluating promising practices, and providing technical assistance to health care organizations, we present a roadmap for reducing racial and ethnic disparities in care. The roadmap outlines a dynamic process in which individual interventions are just one part. It highlights that organizations and providers need to take responsibility for reducing disparities, establish a general infrastructure and culture to improve quality, and integrate targeted disparities interventions into quality improvement efforts. Additionally, we summarize the major lessons learned through the Finding Answers program. We share best practices for implementing disparities interventions and synthesize cross-cutting themes from 12 systematic reviews of the literature. Our research shows that promising interventions frequently are culturally tailored to meet patients' needs, employ multidisciplinary teams of care providers, and target multiple leverage points along a patient's pathway of care. Health education that uses interactive techniques to deliver skills training appears to be more effective than traditional didactic approaches. Furthermore, patient navigation and engaging family and community members in the health care process may improve outcomes for minority patients. We anticipate that the roadmap and best practices will be useful for organizations, policymakers, and researchers striving to provide high-quality equitable care.

Cervical cancer screening, diagnosis and treatment interventions for racial and ethnic minorities: a systematic review.

OBJECTIVES: To systematically review the literature to determine which interventions improve the screening, diagnosis or treatment of cervical cancer for racial and/or ethnic minorities. DATA SOURCES: Medline on OVID, Cochrane Register of Controlled Trials, CINAHL, PsycINFO and Cochrane Systematic Reviews. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS: We searched the above databases for original articles published in English with at least one intervention designed to improve cervical cancer prevention, screening, diagnosis or treatment that linked participants to the healthcare system; that focused on US racial and/or ethnic minority populations; and that measured health outcomes. Articles were reviewed to determine the population, intervention(s), and outcomes. Articles published through August 2010 were included. STUDY APPRAISAL AND SYNTHESIS METHODS: One author rated the methodological quality of each of the included articles. The strength of evidence was assessed using the criteria developed by the GRADE Working Group. RESULTS: Thirty-one studies were included. The strength of evidence is moderate that telephone support with navigation increases the rate of screening for cervical cancer in Spanish- and English-speaking populations; low that education delivered by lay health educators with navigation increases the rate of screening for cervical cancer for Latinas, Chinese Americans and Vietnamese Americans; low that a single visit for screening for cervical cancer and follow up of an abnormal result improves the diagnosis and treatment of premalignant disease of the cervix for Latinas; and low that telephone counseling increases the diagnosis and treatment of premalignant lesions of the cervix for African Americans. LIMITATIONS: Studies that did not focus on racial and/or ethnic minority populations may have been excluded. In addition, this review excluded interventions that did not link racial and ethnic minorities to the health care system. While inclusion of these studies may have altered our findings, they were outside the scope of our review. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Patient navigation with telephone support or education may be effective at improving screening, diagnosis, and treatment among racial and ethnic minorities. Research is needed to determine the applicability of the findings beyond the populations studied.
