To the Editor The recently published Original Investigation by Wadhera and colleagues1 uses a flag for homelessness in State Inpatient Databases of New York, Florida, and Massachusetts from 2010 through 2015 to study quality of care and outcomes of homeless adults with acute cardiovascular conditions. Cardiovascular conditions among homeless persons is a topic deserving of national focus. However, based on our prior work, we abandoned a similar project because the Healthcare Cost and Utilization Project–State Inpatient Databases seemed inaccurate for this purpose.
