In collaboration with the San Diego Medical Examiner's Office and the State of California's controlled Substance Utilization Review and Evaluation System (CURES), the investigators propose to review opioid poisonings over the past 12 months and will send letters to prescribers in California when at least one of the provider's prescription(s) was filled by a patient who died of an opioid poisoning in San Diego County. The letters will be non-judgmental and factual, explaining that a patient of the provider who was being treated with prescription narcotics died of an opioid poisoning. The letter will also encourage judicious prescribing including use of the CURES system before prescribing. The investigators will evaluate physician prescribing practices over 24 months 12 months pre- and 12 months post-letter using data from the CURES database. The investigators' hypothesis is that letters will make the risk of opioids more cognitively available and that physicians will respond by prescribing opioids more carefully. This will result in fewer deaths due to misuse and more frequent use of the CURES system.

The letters will be factual and nonjudgmental, signed by the County Medical Examiner, and would state that a patient they had treated with controlled substances died of an opioid poisoning. The letter will encourage judicious prescribing, and will provide information developed by an advisory group: how to identify and taper unsafe regimens (high dose, polypharmacy, or use of multiple prescribers); how to identify addiction and compassionately refer patients for medication-assisted treatment; and recommendations to avoid bad outcomes (e.g. "do not fire your patient for signs of addiction.") The letter would also encourage use of the CURES system before prescribing, as well as co-prescribing of naloxone.

Average Change Over Time in Dispensed Narcotics
The hypothesis is that the average change over time in dispensed narcotic represented as monthly morphine milligram equivalent (MME) dose will be larger for prescribers receiving the letter intervention, compared to the average change over time for the control prescribers not receiving the letter intervention.
Time frame: 12 months
Number of Opioid Prescriptions for > 90 Morphine Milligram Equivalent (MME) and ≥ 50 MME
The hypothesis is that there will be fewer opioid prescriptions both at a dose \> 90 morphine milligram equivalent (MME) and at a dose ≥ 50 MME among prescribers receiving the letter intervention, compared to control prescribers not receiving the letter intervention.
Time frame: 12 months
Number of Opioid and Benzodiazepine Co-prescriptions
The hypothesis is that there will be fewer opioid and benzodiazepine co-prescriptions for prescribers receiving the letter intervention, compared to control prescribers not receiving the letter intervention.
Time frame: 12 months
Frequency of CURES Use
The hypothesis is that there will be more frequent use of CURES among prescribers receiving the letter intervention, compared to control prescribers not receiving the letter intervention.
Time frame: 12 months
Number of "New Start" Prescriptions
The hypothesis is that there will be fewer prescriptions for opioid naïve patients by prescribers receiving the letter intervention, compared to control prescribers not receiving the letter intervention.
Time frame: 12 months
