Eliminating health disparities is a Healthy People goal. Given the diverse and sometimes broad definitions of health disparities commonly used, a subcommittee convened by the Secretary's Advisory Committee for Healthy People 2020 proposed an operational definition for use in developing objectives and targets, determining resource allocation priorities, and assessing progress. Based on that subcommittee's work, we propose that health disparities are systematic, plausibly avoidable health differences adversely affecting socially disadvantaged groups; they may reflect social disadvantage, but causality need not be established. This definition, grounded in ethical and human rights principles, focuses on the subset of health differences reflecting social injustice, distinguishing health disparities from other health differences also warranting concerted attention, and from health differences in general. We explain the definition, its underlying concepts, the challenges it addresses, and the rationale for applying it to United States public health policy.

The integration of behavioral health (BH) and primary care services has been the subject of considerable attention for almost a decade. Such work has been motivated by the prevalence of chronic health problems in persons with BH conditions and correspondingly high rates of early death. Service integration efforts typically included cross-referral or bidirectional efforts to add some features of primary care to specialty BH settings or the reverse. This article proposes a third approach based on full service and financial integration and shows how it differs substantially from the other 2 models. This new model has the potential to bring much-needed BH services to persons served in primary care settings who have these conditions, while fostering integrated services in specialty settings for those with the most severe mental or substance use conditions. The Patient Protection and Affordable Care Act could provide a valuable opportunity to implement this third model.
