Stratified Reporting

Stratified Reporting

To comprehensively address and eliminate health disparities, it is necessary to measure and publicly report – in a standardized and systematic way – the nature and extent of health care disparities. Stratified Reporting provides useful information for targeting quality improvement activities and resources, monitoring health and drug plan performance, and advancing the development of culturally and linguistically appropriate quality improvement interventions and strategies.
