Increasing emergency department (ED) utilization has contributed to ED overcrowding, with longer ED length of stay (EDLOS) and more patients leaving without being seen (LWBS), and is associated with higher morbidity and mortality rates. Previous studies of provider in triage (PIT) have shown decreased LWBS, but variable improvements in EDLOS. ⋯ We found significantly lower LWBS rates, shorter EDLOS, and shorter door-to-doctor times after PIT implementation. Compared with previous studies in a variety of settings, we found that PIT significantly improved LWBS and all throughput metrics in a safety net setting.

Case Reports
Ultrasound-Guided Serratus Anterior Plane Block for Intractable Herpes Zoster Pain in the Emergency Department.
Herpes zoster (HZV) is a painful vesicular rash that occurs after reactivation in immunosuppressed patients. Analgesia in this patient population has been notoriously difficult. The serratus anterior and erector spinae plane block have both been described as effective thoracic analgesic techniques, but data are limited on their use in HZV. ⋯ A middle-aged man with a history of hypertension and hyperlipidemia presented to the emergency department (ED) with chest and back pain associated with cutaneous rash. Traditional pain regimens were not effective; therefore, a serratus anterior plane block was performed using 25 mL of 0.25% of bupivacaine. The patient's pain decreased from 10 to 2 in 20 min and the patient was discharged without further analgesia. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: As opiate use decreases in prevalence and utility in the ED, alternatives to analgesia are sought. We describe the technique of regional anesthesia using a serratus anterior plane block as another modality that physicians can use to address HZV-related pain.

Sodium nitrite is known to induce methemoglobinemia and hypotension when ingested, but reports of intentional ingestion remain rare. ⋯ We report five cases of severe methemoglobinemia secondary to large sodium nitrite ingestion that were reported to and managed by the California Poison Control System in 2019, resulting in three fatalities. The estimated doses ingested ranged from 15 grams to 113 grams, with one patient surviving after an ingestion of 60 grams. The highest documented methemoglobin level was 73%. The 2 patients who survived received methylene blue early in their clinical course. One patient required higher doses of methylene blue compared with other cases of nitrite-associated methemoglobinemia. In the patients who survived, all symptoms resolved within 24 h. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: These cases highlight the severe toxicity associated with intentional large sodium nitrite ingestion. In management, consideration should be given to administering higher initial or more frequent doses of methylene blue compared with standard practice. Given that sodium nitrite is readily accessible through online vendors, and is being circulated through various suicide forums, it has the potential to be more commonly encountered in the emergency department.

Adult septic arthritis can be challenging to differentiate from other causes of acute joint pain. The diagnostic accuracy of synovial lactate and polymerase chain reaction (PCR) remains uncertain. ⋯ Septic arthritis prevalence in ED adults is lower than reported previously. History and physical examination, synovial lactate, and PCR are inadequate for the diagnosis of septic arthritis. Synovial white blood cell count and Gram stain are the most accurate tests available for septic arthritis.

Human rabies can be prevented through postexposure prophylaxis (PEP). Although the case fatality rate is high, there are only one to three human cases per year in the United States. Despite the low incidence, the cost of rabies diagnostics, prevention, and control is significant. Recommendations exist regarding which patients should receive PEP, though several studies demonstrate a high frequency of unnecessary prescribing of PEP. ⋯ A pharmacist-driven protocol can beneficially influence prescribing habits after potential rabies exposure and is associated with cost savings.
