Protocol - Discrimination in Health Care
Description
The DMS scale is a 7-item instrument that assesses a person’s prior experiences of mistreatment while getting health care that were attributed to race, ancestry, national origin, sex, disability, or age. Each question is rated on a 5-point Likert scale (1-never, 2-rarely, 3-sometimes, 4-most of the time, 5-always).
Specific Instructions
The working group (WG) notes that the DMS scale has been validated for Black/African-American populations, but further testing is warranted among other racial and ethnic groups.

Definition
Discrimination within the health care system can be defined as negative actions or lack of consideration given to an individual or group that occurs because of a preconceived and unjustified opinion and plays an important role in perpetuating health disparities.
Purpose
Evidence suggests that perceived racial discrimination in health care is associated with several important health outcomes, including lower satisfaction with care, reduced adherence to care, lower quality patient/provider communication, underutilization of preventive health services, prolonged symptom duration before diagnosis, and poor overall self-reported health.
