RESUMO
Wildlife professionals routinely use potent sedatives and anesthetics when chemically immobilizing wildlife and zoo species in remote environments. Accidental exposure to these prescription veterinary drugs is rare but could be rapidly fatal. Commonly used agents include opioids and α2 adrenoreceptor agonists. These drugs can be reversed with specific antagonists; however, they are often not approved for human use. The protocol created here can be used by wildlife health professionals in a field setting with basic human emergency medical response training in coordination with local Emergency Medical Services (EMS). Key components include, building local relationships between EMS and wildlife professionals, focused EMS training, administering opioid and α2 adrenergic antagonists off label, and local evacuation procedures. This framework could allow wildlife management agencies or zoos to mitigate the risk of human exposures to these commonly used drugs, significantly improving occupational safety in an otherwise high-risk environment.

OBJECTIVES: North American pit viper, or crotalid bites, remain a low-incidence and potentially high-consequence medical event. Although the venom of these snakes is known to cause tissue, hematologic, and neurologic toxicity, the published literature on North American crotalid bites remains limited. The National Poison Data System, the data repository for the 55 poison control centers in the United States, offers a unique opportunity to examine nationwide trends involving venomous snake bites. METHODS: National Poison Data System cases involving North American crotalids from 2006 to 2020 were analyzed. Data collected included age and type of snake, date, geographic location, pertinent clinical characteristics, treatments administered, and medical outcomes including incidence of "dry" bites and death. RESULTS: A total of 55,914 cases were identified during the 15-year study period. Cases, especially those involving copperheads, increased during the study period. Most of the cases were reported in July. Cases were reported in all 50 states and Washington, DC, with Texas having the most cases (n = 9115). North Carolina had the largest increase in bites during the study period. Moderate or major medical outcomes were documented in 58% (n = 32,584) of cases, with 25% (n = 14,195) being admitted to a critical care unit. Puncture wound, edema, and pain were the most commonly documented symptoms. Antivenom was documented as being administered in 25% (n = 14,151) of cases. Dry bites were reported in <1.5% of cases. Thirty-two deaths were reported, 23 involving rattlesnakes. CONCLUSIONS: This study demonstrates that reported North American crotalid bites appear to be increasing over time and are associated with potentially significant morbidity. Mortality, however, remains low.

BACKGROUND: The US Food and Drug Administration released a warning related to potential adverse effects related to intentional misuse or abuse ingestions of diphenhydramine in September 2020. We sought to evaluate adolescent-aged (13-19 y) diphenhydramine ingestions reported to US poison control centers to characterize these exposures, adverse effects, outcomes, and trends in outcomes and reasons for ingestion. METHODS: The US National Poison Database System was queried for all exposures to diphenhydramine between January 1, 2007 and December 31, 2020. RESULTS: 47,644 ingestions were included for analysis. An increase in the number of ingestions, percentage of cases due to an intentional reason for ingestion and suspected suicide was observed. More serious outcomes, cardiac complications, seizures, and deaths were more common following intentional ingestions and specifically suspected suicide over misuse or abuse. CONCLUSIONS: Adolescent ingestions of diphenhydramine increased between 2007 and 2020. More serious outcomes, intentional reasons, and suspected suicide also increased over the study interval. Suspected suicide was associated with cardiac complications, seizures, coma, and death at higher rates than misuse or abuse. While misuse and abuse remain a concern, public health interventions focusing on the risk that diphenhydramine pose as an agent of suicide attempt may be of higher impact.

INTRODUCTION: We sought to compare physician assistant (PA) and nurse practitioner (NP) practice in United States emergency departments (ED) based on ED visits as reported by the National Hospital Ambulatory Medical Care Survey (NHAMCS). METHODS: We performed a retrospective, secondary analysis of the 2010 to 2017 NHAMCS with analysis of ED visits, patient demographics, and hospital characteristics. RESULTS: Between 2010 to 2017, 21.0% (95% confidence interval, [CI] +/-3.1%) of ED visits were seen by either a PA/NP (with and without physician involvement) and 8.6% (+/-2.9%) were seen by PA/NP alone. We identified an increase for NP visits between 2014-2016 and found that PA/NP visits share many of the same characteristics. CONCLUSION: While emergency medicine has predominately been a specialty for PAs, the number of ED visits with NPs has been increasing over the past several years. While there are some differences, PAs/NPs share many similar practice characteristics in the ED.

BACKGROUND: Physician Assistants (PAs) are widely used in United States (US) Emergency Departments (EDs). We sought to characterize ED PA utilization and practice characteristics in US EDs 2010-2017. METHODS: A retrospective, secondary analysis of the 2010 to 2017 Center for Disease Control's National Hospital Ambulatory Medical Care Survey (NHAMCS) was performed. National estimates of ED visits involving PAs alone (PA), PAs with physician involvement (PA+), or physician only (PHYS) were analyzed for patient demographics and hospital characteristics. RESULTS: Between 2010 and 2017, an estimated 1 billion US ED visits occurred. 5.0% (95% confidence interval [CI] ±2.7%) of visits were seen by a PA, and 8.2% (±2.7%) by a PA+; 76.3% (±7.2%) by PHYS. No linear trends by year were identified in PA or PA+ visits. PA acuity was highest for semi-urgent/nonurgent (56.4%, ±10.7%). PA see the minority of ambulance arrival [5.8% (±1.3)] and admit less patients [1.7% (±0.7%)]. Less laboratory [53.3% (±10.2%) vs. 67.0% (±6.2%)] and radiographic [38.8% (±6.6%) vs. 51.6% (±4.6%) studies were performed during PA vs. PHYS visits. PA visits were most common for patients 25-44 years old (yo) (32.9%, ±6.2%) and 15-24 yo (19.2%, ±3.7%). Most PA visits result in a length of stay (LOS) between 1 and 1.9 h (32.9%, ±6.7%) compared to most PHYS visits resulting in a LOS >3 h (40.3%, ±3%). CONCLUSIONS: From 2010 to 2017, no linear trends in US ED PA and PA+ utilization were identified. PHYS continue to see the majority of ED patients.

OBJECTIVE: We sought to examine ADHD modified release (MR) and immediate release (IR) stimulant ingestion exposures reported to the National Poison Data System (NPDS) to characterize the nature of the exposures and the outcomes associated with them. METHODS: The NPDS was queried for all single-substance exposures to MR and IR ADHD preparations between January 1, 2007 and December 31, 2017. MR and IR preparations were identified by a generic code of "amphetamine and related compounds" or "methylphenidate" and specific product name containing XR, CD, ER, LA, and SR. RESULTS: A total of 15,796 MR ingestions and 23,418 IR ingestions were identified and followed to known outcome. The majority of ingestions occurred in male patients and in own residence. More serious outcomes (moderate, major, or death) were more common in adult IR and MR ingestions as compared to pediatric; rates of serious outcome increased with age amongst pediatric ingestions. Unintentional ingestions were more common in both MR and IR pediatric cases while intentional ingestions occurred more frequently in adult cases. Symptoms consistent with a hyperadrenergic state were experienced in adult and pediatric patients for both MR and IR ingestions. Supportive care including benzodiazepine administration was more common in IR than MR ingestions. Decontamination with whole bowel irrigation was infrequent. CONCLUSION: Rates of more serious outcome were similar between IR and MR ADHD stimulant ingestions. More serious outcomes were associated with advancing age and intentional ingestions. Similar rates of agitation, tachycardia, and hypertension were experienced by pediatric IR and MR ingestions while more common in adult IR as compared to MR ingestions. Rates of decontamination with whole bowel irrigation were overall low.

BACKGROUND: Medications for opioid use disorder (MOUD) including buprenorphine is recommended for patients with opioid use disorders. We sought to evaluate the frequencies of respiratory depression, intubation, and naloxone administration, and clinical outcomes among patients reported to the National Poison Database System (NPDS) following single-substance and multiple-substance buprenorphine oral exposures. METHODS: NPDS was queried for all MOUD-approved buprenorphine product exposures between 1 January 2003 and 31 December 2019. Data abstracted included year, route, gender, age, site of exposure, management site, medical outcome, recorded "related" respiratory depression ("respiratory rate <10 breaths/min and/or a SpO2 (pulse oximetry)≤90%), reported administration of naloxone and intubation in oral exposure cases followed to known outcome. Concomitant products were also recorded in multiple-substance buprenorphine cases. RESULTS: 27,275 (11,010 multiple and 16,265 single) buprenorphine oral exposures were identified and followed to known outcome. A 65-fold increase in reported cases was reported over the study interval. A steady increase in the frequency of more serious outcomes by year was also observed. Respiratory depression occurred at a frequency of 11.8% (pediatric single-substance), 11.2% (pediatric multiple-substance), 11.3% (adult single-substance), and 11.9% (adult multiple-substance). Among oral exposures of buprenorphine and only one other product, benzodiazepines, opioids, ethanol, and amphetamines were most common. CONCLUSIONS: Oral exposures have increased substantially between 2003 and 2019. More serious outcomes including deaths following oral exposures to buprenorphine have also increased over the same interval for both adult and pediatric patients. Clinically significant rates of respiratory depression in both adult and pediatric patients when taken alone and with additional substances were observed.

BACKGROUND: Physician Assistants (PAs) and Nurse Practitioners (NPs) are widely utilized in United States (US) Emergency Departments(EDs). We sought to characterize ED PA and NP utilization and practice characteristics in US EDs 2010-2017. METHODS: A retrospective, secondary analysis of the Center for Disease Control's National Hospital Ambulatory Medical Care Survey was performed. National estimates of ED visits involving PAs/NPs alone (PA/NP), PAs/NPs with physician involvement (PA/NP+), or physician only (PHYS) were analyzed for patient demographics and hospital characteristics. RESULTS: Between 2010 and 2017, 1 billion US ED visits occurred. 8.4% (±4.2%) of visits were seen by a PA/NP, and 11.8% (±4.5%) by a PA/NP+; 76.3% (±7.2%) by PHYS. There was an increase in utilization by PA/NP observed in 2016. PA/NP acuity was highest for semi-urgent/nonurgent (53.2%, ±8.6%). PA/NP see the minority of ambulance arrivals [5.4% (±1.2%)] and admit less patients overall [1.6% (±0.7%)]. Less laboratory [53.6% (±10.0%) vs. 67.0% (±6.2%)] and radiographic [38.0% (±7.0%) vs. 51.6% (±4.6%)] studies were performed during PA/NP only vs. PHYS visits. PA/NP visits were most common for patients 25-44 years old (yo) (31.1%, ±5.5%) and 0-15 yo (23.9%, ±4.7%). Most PA/NP visits result in a length of stay (LOS) between 1 and 1.9 h (33.4%, ±5.7%) compared to most PHYS visits resulting in a LOS greater than 3 h (40.3%, ±3%). CONCLUSIONS: From 2010 to 2015, PA/NP utilization remained stable until an increase in 2016. There was a decrease in 2017. Various PA/NP patient characteristics are significant compared to PHYS. PHYS continue to see most ED patients.

BACKGROUND: Carnett's sign (CAR) and Closed Eye sign (CE) have been suggested for use in the emergency department setting in the management of abdominal pain. The present study sought to determine the sensitivity/specificity of CAR and CE for pathological CT findings as a primary outcome and for subsequent hospital admission or surgical intervention as secondary outcomes in a community emergency department setting. METHODS: A convenience sample of adults (≥18 y) presenting with acute (<48 h) nontraumatic and non-postoperative abdominal pain determined by treating provider to warrant CT imaging were eligible for enrollment. Treating providers completed a datasheet describing physical examination findings prior to CT imaging. RESULTS: 320 patients were enrolled. 245/320 (76.5%) of enrolled patients had findings on CT Imaging. CAR+ was recorded in 145 and CAR- in 175 patients. CE+ was in 187 and CAR- in 133 patients. Sensitivity and specificity of CAR- for hospital admission was 42.2% and 38.9% and for surgery-44.8% and 43.1%. Sensitivity and specificity of CE- for hospital admission was 28% and 51.6% and for surgery-25.9% and 55%. CAR+ patients were more likely to be admitted or undergo surgery as compared to CAR-. CE+ patients were more likely to be admitted or undergo surgery as compared to CAR-. There were no differences in frequency of pathological CT findings between CAR+ and CAR- or CE+ and CE- patients. CONCLUSION: CAR and CE are neither sufficiently sensitive nor specific for use in the emergency department setting. CT findings were equally likely in CAR+ and CAR- patients. CT Findings were also equally likely in CE+ and CE- patients.

BACKGROUND: In 2014, California signed into law AB1535 permitting pharmacists to dispense naloxone upon request and without physician or midlevel provider prescription. OBJECTIVE: We sought to determine pharmacist knowledge of AB1535, participation, availability of naloxone, future plans for participation, and out-of-pocket charges to consumers amongst outpatient pharmacies in selected California counties. METHODS: All pharmacies in Plumas, Lake, Lassen, Humboldt, Shasta, Fresno, and San Diego Counties were identified. Between January 30 and March 30, 2017, pharmacies meeting inclusion criteria were contacted and the pharmacist-on-duty were queried regarding knowledge, participation, availability, and cost of naloxone. RESULTS: A total of 2296 pharmacies were identified in the 7 counties. Twenty-six were unwilling or unable to participate and an additional 1648 were excluded because of licensing or special pharmacy status. Six-hundred-twenty-two pharmacies completed the survey. There was variation in knowledge of AB1535, participation in, immediate availability of naloxone, charge, and expressed future interest in participation identified. Charge to consumers was similarly variable amongst surveyed pharmacies within counties. CONCLUSIONS: Despite considerable public health and political support, the passage of CA AB1535 has not resulted in broad current, future planned participation, or availability of naloxone in selected counties. Out-of-pocket costs to the consumer remain highly variable.

BACKGROUND: Synovial lactate is a promising biomarker to distinguish septic from aseptic arthritis. If available as a point-of care test, synovial lactate would be rapidly available to aid the emergency provider in clinical decision making. This study assesses the test characteristics of synovial lactate obtained using an EPOC© point-of-care (POC) analyzer to rapidly distinguish septic from aseptic arthritis in the emergency department. METHODS: We enrolled a convenience sample of patients with possible septic arthritis presenting to the emergency department at a large urban academic center between October 2016 and April 2018. Enrolled patients underwent arthrocentesis based on the clinical judgment of the treating provider. We obtained synovial lactate levels (SLL) from the POC device. Standard laboratory analysis, synovial fluid culture, emergency and hospital course, operative procedures, antibiotics, and discharge diagnosis were abstracted from the electronic medical record. RESULTS: Thirty-nine patients undergoing forty separate arthrocentesis procedures were enrolled in this study over the two-year period. The sensitivity and specificity of SLLâ¯≥â¯5â¯mmol/L was 0.55 and 0.76 respectively, with +LR 2.3 and -LR 0.6. The sensitivity and specificity of SLLâ¯≥â¯10â¯mmol/L was 0.27 and 0.97 respectively, with +LR 7.9 and -LR 0.8; SLLâ¯≥â¯10â¯mmol/L performed similarly to overall synovial WBCâ¯≥â¯50,000/µL by conventional laboratory testing. CONCLUSION: It is feasible to obtain a synovial lactate level using the EPOC© POC device. In our study, POC SLL performs similarly to other markers used to diagnose septic arthritis. Further study with larger sample sizes is warranted.

BACKGROUND: Behavioral emergencies account for a significant portion of emergency department (ED) visits in the United States. Substance abuse is common in this population and may precipitate or exacerbate preexisting psychiatric illness. Contrary to ED policy guidelines, many behavior health centers (BH) require a urine drug screen (UDS) in stable patients prior to transfer. OBJECTIVE: We sought to determine the role of the UDS in ED length of stay (LOS), cost, and charges to patients and inpatient psychiatric care. METHODS: We performed a retrospective chart review of all patients transferred to an in-network BH from September 1-30, 2014. Clinical data were extracted and analyzed from our electronic medical record, including records from both the ED visit and the BH stay. RESULTS: There were 205 patient encounters identified; 89 patients had a UDS performed in the ED and 89% were obtained after the ED medical clearance. LOS were similar between the two groups, however, time to ED departure from time of medical clearance was delayed in the UDS group. BH providers mentioned UDS results < 25% of the time and no confirmatory tests were performed. There was no difference in BH LOS or discharge diagnosis of substance-abuse disorder. Patient charges for UDS over the month totaled $21,093. CONCLUSION: The UDS did not seem to have any significant effect on inpatient psychiatric care; whereas ED LOS and cost were both negatively affected. Based on these results, the UDS seems to be of little-to-no benefit in the setting of acute psychiatric illness.

Synthetic cannabinoids (SC), are a novel class of designer drugs which emerged as a drug of abuse in the late 2000's. We report a case series of 6 patients who may have smoked a synthetic cannabinoid product in a remote wilderness setting. They presented with varying degrees of altered mental status, agitation, and seizures. Two were confirmed to have AB-PINACA, ADB-PINACA and their respective pentanoic acid metabolites in biological specimens via liquid chromatography time-of-flight mass spectrometry (LC-TOF/MS). Both compounds had DEA Schedule I classification at the time of case presentation, and 22 SCs are currently temporary or permanent DEA Schedule I. More than 150 SCs are known to date, and new compounds are appearing at a rapid rate on darknet and surface web e-commerce websites, marketed as "research chemicals" or "legal highs." The scale and rapidity of SC evolution make legal control and analytical detection difficult. Nontargeted testing with liquid chromatography high resolution mass spectrometry (LC-HRMS), examining both parent compounds and metabolites, is the ideal method for novel SC identification and confirmation. Due to full agonism at the cannabinoid receptors CB1 and CB2, clinical effects are more severe than marijuana, which is a partial cannabinoid receptor agonist. They include agitated delirium, lethargy and coma, seizures, tachycardia, hypertension, and hallucinations, among other findings. Treatment is primarily symptomatic and aimed at airway protection and control of agitation and seizures. SCs do not appear to be abating anytime soon and require the cooperation of law enforcement, analytical scientists, and clinicians to adequately control. This article is part of the Special Issue entitled 'Designer Drugs and Legal Highs.'
