Understanding Disparities in Persons with Multiple Chronic Conditions: Research Approaches and Datasets. 4. Findings from MCC Literature on Disparities


Research on disparities among the MCC population is not well-developed. Many studies have looked at disparities among individuals with a specific chronic condition, even with two and three chronic conditions, but the research has not been synthesized or considered as a body of research on MCC. Governmental priorities such as the HHS Interagency Workgroup’s objective to address disparities in MCC patients through research on different socio-demographic groups, are intended to spur studies to fill the knowledge gap. As stated earlier in the report, research on multiple chronic conditions  is lacking in general, and research on disparities in the MCC population even more so.

Similar to other forms of disparities research, the studies that have been conducted on the MCC population to-date have been descriptive in nature. The research has focused on identifying the existence of potential disparities in the MCC population, rather than examining the root-causes of these disparities or potential measures for resolution, and is limited in its ability to suggest evidence-based  interventions to reduce disparities among persons with MCC.

Based on the findings from our literature review, key informant interviews, and TAG meetings, we summarized the available MCC disparities research into the following topic areas:

  1. Non-disease specific disparities
  2. Most common disease clusters in men and women
  3. Disease-specific disparities

The literature related to each topic is summarized in turn, below. We describe the kinds of research being conducted under each topic and highlight the findings.
