In a randomized clinical trial (NCT02790476), Doctor et al1 studied the effect of notifying physicians of a patient’s fatal drug overdose within 12 months of a scheduled drug prescription for that patient. The physicians received an injunction to prescribe safely from their county's medical examiner. This intervention was associated with reductions in overall, high-dose, and new opioid prescriptions. In this article, we evaluate the association of these letters with benzodiazepine prescribing, which also contribute to drug deaths.
