Critical Elements in the Design of Culturally Appropriate Interventions Intended to Reduce Health Disparities: Immunization Rates among Hispanic Seniors in New Mexico

Abstract

The importance of immunization in protecting seniors against influenza and pneumonia has long been recognized. Nevertheless, immunization rates among Medicare beneficiaries continue to fall short of what is both desirable and achievable. The problem is even more acute among certain racial and ethnic groups in the United States within which rates are below the rate for the country as a whole. This is true in New Mexico where 40 percent of the population is estimated to be Hispanic.

As part of its work on behalf of the Centers for Medicare & Medicaid Services (CMS), the New Mexico Medical Review Association (NMMRA) undertook a project aimed both at reducing the disparities that exist in immunization status between the Hispanic and non-Hispanic population in the state and attempting to increase overall rates in the state for all groups. Developing interventions to reduce disparaties in immunization rates between Hispanic seniors and the rest of the senior population requires more than a straightforward review of the literature and must take into account not only the cultural differences that exist between Hispanics and non-Hispanics but, certainly, in the case of New Mexico, it must attempt to understand the richness and diversity that exists within the Hispanic communities across the state.

To do otherwise runs the risk of designing interventions that are at best ineffective and at worst culturally insensitive and potentially damaging to future efforts to improve health status.

This article describes the process undertaken by NMMRA, a Medicare Quality Improvement Organization (QIO), to collect qualitative data from three culturally different groups of Hispanics in New Mexico. The data are used to design interventions that will increase immunization rates for all Hispanics in New Mexico.
