IntroductionCannabinoid hyperemesis syndrome (CHS) is an entity associated with cannabinoid overuse. CHS typically presents with cyclical vomiting, diffuse abdominal pain, and relief with hot showers. Patients often present to the emergency department (ED) repeatedly and undergo extensive evaluations including laboratory examination, advanced imaging, and in some cases unnecessary procedures. They are exposed to an array of pharmacologic interventions including opioids that not only lack evidence, but may also be harmful. This paper presents a novel treatment guideline that highlights the identification and diagnosis of CHS and summarizes treatment strategies aimed at resolution of symptoms, avoidance of unnecessary opioids, and ensuring patient safety.MethodsThe San Diego Emergency Medicine Oversight Commission in collaboration with the County of San Diego Health and Human Services Agency and San Diego Kaiser Permanente Division of Medical Toxicology created an expert consensus panel to establish a guideline to unite the ED community in the treatment of CHS.ResultsPer the consensus guideline, treatment should focus on symptom relief and education on the need for cannabis cessation. Capsaicin is a readily available topical preparation that is reasonable to use as first-line treatment. Antipsychotics including haloperidol and olanzapine have been reported to provide complete symptom relief in limited case studies. Conventional antiemetics including antihistamines, serotonin antagonists, dopamine antagonists and benzodiazepines may have limited effectiveness. Emergency physicians should avoid opioids if the diagnosis of CHS is certain and educate patients that cannabis cessation is the only intervention that will provide complete symptom relief.ConclusionAn expert consensus treatment guideline is provided to assist with diagnosis and appropriate treatment of CHS. Clinicians and public health officials should identity and treat CHS patients with strategies that decrease exposure to opioids, minimize use of healthcare resources, and maximize patient safety.
Most opioid prescription deaths occur among people with common conditions for which prescribing risks outweigh benefits. General psychological insights offer an explanation: People may judge risk to be low without available personal experiences, may be less careful than expected when not observed, and may falter without an injunction from authority. To test these hypotheses, we conducted a randomized trial of 861 clinicians prescribing to 170 persons who subsequently suffered fatal overdoses. Clinicians in the intervention group received notification of their patients' deaths and a safe prescribing injunction from their county's medical examiner, whereas physicians in the control group did not. Milligram morphine equivalents in prescriptions filled by patients of letter recipients versus controls decreased by 9.7% (95% confidence interval: 6.2 to 13.2%; < 0.001) over 3 months after intervention. We also observed both fewer opioid initiates and fewer high-dose opioid prescriptions by letter recipients.
Background: Prescription drug-related fatalities remain a significant issue in the United States, yet there is a relative lack of knowledge on the specialty-specific prescription patterns for drug-related deaths. Methods: We designed a study that investigated medical examiner reports of prescription drug-related deaths that occurred in San Diego County during 2013. A Prescription Drug Monitoring Program search was performed on each of these cases to ascertain which physician specialties had prescribed controlled substances to these patients. The data were analyzed for each specialty, including pills per prescription, type of prescription, doctor shoppers (4 physicians + 4 pharmacies over 1 year), and chronic users (≥3 consecutive months of medications). Main findings: In 2013, 4.5% of all providers in San Diego County wrote a prescription for a patient who died a prescription-related death. There were a total of 713 providers who prescribed 4366 medications totaling 328928 pills. Overall, emergency physicians gave the lowest number of prescriptions per provider (1.6), whereas pain management provided the highest amount per provider (12.9). Most prescriptions went to doctor shoppers (N50%) and chronic users (95.8%). Hydrocodone was the most frequently prescribed medication to those patients whose deaths were related to prescription drugs. Conclusions: Emergency physicians appear to provide fewer prescriptions to those patients who die due to prescription drugs. Emergency physicians do, however, account for a significant proportion of total providers in this study. These results highlight the need to use Prescription Drug Monitoring Program data to closely monitor prescription patterns and to intervene when necessary.
