To the Editor: Dr Pletcher and colleagues1 analyzed trends in US emergency departments in opioid prescribing for pain complaints and found considerable differences by race/ethnicity. However, the authors were unable to account for patients' socioeconomic status (SES) and did not consider the potential role of SES in their results. We believe that the observed differences in opioid prescribing by race/ethnicity could be explained by differences in SES.
