In addition, adjustment indices and a comorbidity scoring system designed to prevent bias from SMM risk assessment were developed and validated in locations without adequate race and ethnicity representation. This study analyzed data from Florida, Maryland, Kentucky, Washington, and New York to externally validate the Bateman and Leonard indices accounting for sociodemographic and racial and ethnic diversity.
