Using a health equity lens to measure patient experiences of care in diverse health care settings.

ABSTRACT

People who are structurally disadvantaged and marginalized often report poor health care experiences, such as inequitable treatment, due to intersecting forms of stigma and discrimination. There are many measures of patient experiences of care, however, few are designed to measure equity-oriented health care. In alignment with ongoing calls to integrate actions in support of health equity, we report on the development and testing of patient-reported experience measures that explicitly use a health equity and intersectional lens. Our analysis focuses on two different scales the Equity-Oriented Health Care Scale-Ongoing, which was evaluated in primary health care settings where patients have an ongoing relationship with providers over time, and the Equity-Oriented Health Care Scale-Episodic, which was tested in an emergency department where care is provided on an episodic basis. Item Response Theory was used to develop and refine the scales. The psychometric properties of each scale were also evaluated. The Equity-Oriented Health Care Scale-Ongoing was first tested with a cohort of 567 patients. The Equity-Oriented Health Care Scale-Episodic was subsequently tested in an emergency department setting with 284 patients. Results of the Item Response Theory analysis for each scale yielded a brief index that captured the level of equity-oriented care when care is ongoing (12 items) or episodic (9 items). Both scales showed evidence of internal consistency and concurrent validity, based on a high correlation with quality of care. They are brief, easy-to-administer patient-reported experience measures that can support organizations to monitor quality of care. Their availability enhances the possibility of measuring equity-oriented health care in diverse contexts and can provide nuanced understandings of quality of care through an intersectional and equity lens.
