Trends in oxycodone and oxycodone-containing analgesics administration for back pain in emergency departments in the USA (2007-2018).

BACKGROUND: To describe trends in oxycodone and oxycodone-containing analgesic prescribing for the treatment of back pain among adults in emergency departments (EDs) in the USA from 2007 to 2018. METHODS: Data were gathered from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2007 to 2018. The study population included individuals of all ages presenting to USA EDs. The NHAMCS reasons for visit and oxycodone drug ID codes were used to isolate patients with back pain. The main outcome was the proportion of oxycodone and oxycodone-containing analgesics prescribed for back pain in the EDs over the specified time period. RESULTS: There was a relative decrease in the overall administration of oxycodone for back pain in the EDs by 62.3% from 2007 (244,000 visits) to 2018 (92,000 visits). The proportion of ED patients prescribed with oxycodone-containing analgesics for back pain increased among patients aged 45 years and older (from 43.8% to 57.6%), female patients (from 54.5% to 62.0%), black patients (from 22.5% to 30.4%), and Hispanic/Latino patients (from 9.4% to 19.6%). Oxycodone/acetaminophen was most prescribed and accounted for 90.2% of all oxycodone-containing analgesics in 2007, with a decrease to 68.5% in 2018. Pure oxycodone was the second most prescribed medication, accounting for 6.1% in 2007 and 31.5% in 2018. CONCLUSION: The overall number of oxycodone-containing analgesics decreased significantly from 2007 to 2018. However, that number trended upward in 45-year-old and older, female, black, or Hispanic/Latino patients from 2007 to 2018. The total amount of pure oxycodone increased significantly from 2007 to 2008.

Comparison of Nebulized Ketamine to Intravenous Subdissociative Dose Ketamine for Treating Acute Painful Conditions in the Emergency Department: A Prospective, Randomized, Double-Blind, Double-Dummy Controlled Trial.

STUDY OBJECTIVE: We aimed to assess and compare the analgesic efficacy and adverse effects of intravenous subdissociative-dose ketamine to nebulized ketamine in emergency department (ED) patients with acute painful conditions. METHODS: We conducted a prospective, randomized, double-blind, double-dummy clinical trial in adult patients (ages 18 and older) with a numerical rating scale pain score of ≥5. We randomized subjects to receive either a single dose of 0.3 mg/kg of intravenous (IV) ketamine or 0.75 mg/kg of nebulized ketamine through a breath-actuated nebulizer. Primary outcome was the difference in pain scores on the numerical rating scale between groups at 30 minutes postmedication administration. The secondary outcomes included the need for rescue analgesia, occurrences of adverse events in each group, and the difference in pain scores at 15, 30, 60, 90, and 120 minutes. We calculated a 95% confidence interval (CI) for a mean difference at 30 minutes, with a minimum clinically important difference set at 1.3 points. RESULTS: We enrolled 150 subjects (75 per group). Mean pain scores through numerical rating scale were 8.2 for both groups at baseline, which decreased to 3.6 and 3.8 at 30 minutes, yielding a mean difference of 0.23 (95% CI -1.32 to 0.857). We observed no clinically concerning changes in vital signs. No serious adverse events occurred in any of the groups throughout the study period. CONCLUSION: We found no difference between the administration of IV and nebulized ketamine for the short-term treatment of moderate to severe acute pain in the ED, with both treatments providing a clinically meaningful reduction in pain scores at 30 minutes.

Establishing a rapid assessment service for patients with suspected malignancies for expedited outpatient management.

BACKGROUND: 11% of new cancer diagnoses occur in the emergency department. Historically, these diagnoses disproportionately affect underserved patient populations and are associated with poor outcomes. This is an observational study of the Rapid Assessment Service (RAS) program, which aims to provide timely outpatient follow-up and facilitate a diagnosis for patients discharged from the emergency department with suspected malignancies. METHODS: We performed a retrospective chart review of 176 patients who were discharged from the emergency department with RAS clinic follow up between February 2020 and March 2022. We manually chart reviewed 176 records in order to determine the average time to RAS clinic appointment, average time to diagnosis, and the final diagnosis based on biopsy. RESULTS: 163 of 176 patients (93%) discharged to RAS received reliable follow-up care. 62 of the 176 patients (35%) followed up in the RAS clinic with a mean of 4.6 days. 46 of the 62 patients (74%) who followed up in the RAS clinic were ultimately diagnosed with a new cancer, with a mean time to diagnosis of 13.5 days. The leading new cancer diagnoses included: lung, ovarian, hematologic, head and neck, and renal cancers. CONCLUSIONS: Creating a Rapid Assessment Service facilitated an expedited oncologic work-up and diagnosis in an outpatient setting.

Oral Aspirin/ketamine versus oral ketamine for emergency department patients with acute musculoskeletal pain.

OBJECTIVE: The purpose of this study is to investigate if an orally administered combination of aspirin and ketamine will provide better analgesia than a ketamine alone in adult patients presenting to the Emergency Department (ED) with acute musculoskeletal pain. METHODS: We conducted a prospective, randomized, open-label trial of ED patients aged 18 and older presenting with moderate to severe acute musculoskeletal pain as defined by an 11-point numeric rating scale (NRS) with an initial score of ≥5. Patients were randomized to receive either 324 mg of VTS-Aspirin™ and 0.5 mg/kg of oral ketamine (AOK) that is directly swallowed or 0.5 mg/kg of oral ketamine (OK) alone that is swished first and then swallowed. Patients were assessed at baseline, 30, 60, 90, and 120 min. The primary outcome was a difference in pain scores between the two groups at 60 min post-administration. Secondary outcomes included adverse events and the need for rescue analgesia. RESULTS: We enrolled 60 patients in the study (30 per group). The difference in mean pain scores at 60 min between the AOK and OK groups was 2.6 [95% CI: 1.38-3.77] showing a lower mean pain score in the OK group. At 60 min, the AOK group had a change in mean pain score from 8.4 to 6.3 (difference 2.1; 95% CI: 1.35-3.00). The OK group had a change in mean pain score from 7.8 to 3.7 (difference 4.1, 95% CI: 3.25-4.90). No clinically concerning changes in vital signs were observed. No serious adverse events occurred in either group. The most commonly reported adverse effects were dizziness and fatigue. None of the participants required rescue analgesia at 60 min post-medications administration. CONCLUSION: The administration of an oral combination of VTS-Aspirin ™ and ketamine resulted in less analgesia compared to oral ketamine alone, for the short-term treatment of moderate to severe acute musculoskeletal pain in the ED. CLINICALTRIALS: govRegistration: NCT04860804.

Analgesic Efficacy of Oral Aspirin/Ketamine Combination for Management of Acute Musculoskeletal Pain in the Emergency Department - A Proof of Concept Pilot Study.

BACKGROUND: Musculoskeletal pain (MSK) affects one out of three adults and is the most common source of significant long-term pain, physical disability, and under-treatment in the emergency department (ED). OBJECTIVE: We aimed to assess the analgesic efficacy of a combination of oral VTS-Aspirin® (Vitalis Analgesics, New York, NY) and ketamine in managing acute MSK pain in adult ED patients. METHODS: This was a prospective, proof-of-concept, single-arm, pilot study evaluating the analgesic efficacy of a single dose of oral combination of VTS-Aspirin and ketamine in adult ED patients with acute moderate-to-severe MSK pain. The primary outcome included the difference in pain scores on an 11-point numeric pain rating scale at 60 min. Secondary outcomes included the need for rescue analgesia, the occurrence of adverse events at 60 min, and a change in pain scores at 120 min. RESULTS: We enrolled 25 subjects in the study. The mean baseline pain score was 8.6 and the mean pain score at 60 min decreased to 4.8. The oral ketamine dose ranged from 24 mg to 50 mg, with a mean dose of 37.8 mg. No clinically concerning changes in vital signs were noted. No serious adverse events occurred in any of the subjects. Majority of adverse effects were transient and weak in intensity. CONCLUSION: We demonstrated that administration of an oral combination of VTS-Aspirin and ketamine to adult ED patients with acute MSK pain resulted in clinically significant pain relief in 80% of enrolled subjects.

Paraphimosis Pain Treatment with Nebulized Ketamine in the Emergency Department.

BACKGROUND: Paraphimosis is an acute urological emergency occurring in uncircumcised males that can lead to strangulation of the glans and painful vascular compromise. Ketamine has been used in the emergency department (ED) as an anesthetic agent for procedural sedation, and when administrated in a sub-dissociative dose (low dose) at 0.1-0.3 mg/kg, ketamine has been utilized in the ED and prehospital settings for pain control as an adjunct and as an alternative to opioid, as well as for preprocedural sedation. This report details the case of a pediatric patient who presented to our Pediatric ED with paraphimosis and had his procedural pain treated with ketamine administrated via a breath-actuated nebulizer (BAN). CASE REPORT: This case report illustrates the potential use of ketamine via BAN to effectively achieve minimal sedation for a procedure in pediatric patients in the ED. The patient was a 15-year-old boy admitted to the Pediatric ED complaining of groin pain due to paraphimosis. The patient was given 0.75 mg/kg of nebulized ketamine via BAN, and 15 min after the medication administration the pain score was reduced from 5 to 1 on the numeric pain rating scale. The patient underwent a successful paraphimosis reduction without additional analgesic or sedative agents 20 min after the administration of nebulized ketamine. The patient was subsequently discharged home after 60 min of monitoring, with a pain score of 0. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The use of nebulized ketamine via BAN might represent a viable, noninvasive way to provide a mild sedative and be an effective analgesic option for managing a variety of acute painful conditions and procedures in the pediatric ED.

Take-Pause: Efficacy of mindfulness-based virtual reality as an intervention in the pediatric emergency department.

BACKGROUND: Emergency department (ED) visits are known to be anxiety-ridden and stress-provoking experiences especially in the pediatric population. Distraction techniques have been used as a means to reduce anxiety and stress thereby facilitating care in the ED and making the visit less unpleasant. Our study aimed to evaluate the effectiveness of an active and immersive distraction technique, using a mindfulness-based virtual reality (VR) program (Take-Pause), to alleviate anxiety in pediatric ED patients. METHODS: A prospective, randomized, single-blinded study, evaluating ED patients aged 13-17 years with a chief complaint of acute pain was conducted. Patients were randomized either to the active distraction intervention (VR group), utilizing the VR headset for 5 min, or to the passive distraction intervention (iPad group), playing on an iPad for 5 min. The primary outcome was a difference in the change in anxiety scores on the Spielberger State-Trait Anxiety Inventory between the two groups. Secondary outcomes included a difference in pain scores, respiratory rate, and heart rate between the groups. RESULTS: A total of 110 subjects were enrolled. At 15 min, the mean anxiety score for the VR group improved by 10 points versus 6 points in the iPad group (p < 0.001; 95% confidence interval = 0.44 to 7.6). There was no statistical significance in the reduction of pain scores (p = 0.953) and respiratory rates (p = 0.776) between the groups. Patients enrolled in both groups did not experience any adverse effects. CONCLUSION: Take-Pause, offering an active and immersive distraction technique, is more effective than a passive distraction approach to lower anxiety levels in adolescent ED patients.

Comparison of Nebulized Ketamine at Three Different Dosing Regimens for Treating Painful Conditions in the Emergency Department: A Prospective, Randomized, Double-Blind Clinical Trial.

STUDY OBJECTIVE: We aimed to assess and compare the analgesic efficacies and adverse effects of ketamine administered through a breath-actuated nebulizer at 3 different dosing regimens for emergency department patients presenting with acute and chronic painful conditions. METHODS: This was a prospective, randomized, double-blinded trial comparing 3 doses of nebulized ketamine (0.75 mg/kg, 1 mg/kg, and 1.5 mg/kg) administered through breath-actuated nebulizer in adult emergency department patients aged 18 years and older with moderate to severe acute and chronic pain. The primary outcome included the difference in pain scores on an 11-point numeric rating scale between all 3 groups at 30 minutes. Secondary outcomes included the need for rescue analgesia (additional doses of nebulized ketamine or intravenous morphine) and adverse events in each group at 30 and 60 minutes. RESULTS: We enrolled 120 subjects (40 per group). The difference in mean pain scores at 30 minutes between the 0.75 mg/kg and 1 mg/kg groups was 0.25 (95% confidence interval [CI] 1.28 to 1.78); between the 1 mg/kg and 1.5 mg/kg groups was -0.225 (95% CI -1.76 to 1.31); and between the 0.75 mg/kg and 1.5 mg/kg groups was 0.025 (95% CI -1.51 to 1.56). No clinically concerning changes in vital signs occurred. No serious adverse events occurred in any of the groups. CONCLUSION: We found no difference between all 3 doses of ketamine administered through breath-actuated nebulizer for short-term treatment of moderate to severe pain in the emergency department.

Analgesic efficacy of morphine sulfate immediate release vs. oxycodone/acetaminophen for acute pain in the emergency department.

OBJECTIVE: Previous research demonstrated that administration of Morphine Sulfate Immediate Release (MSIR) results in similar analgesic efficacy to Oxycodone but with significantly lesser degrees of euphoria and reward. The purpose of this study sit to investigate if MSIR combined with Acetaminophen can serve as an opioid analgesic alternative to Oxycodone combined with acetaminophen (Percocet) for acute pain in the Emergency Department (ED). METHODS: A prospective, randomized, double-blind trial of ED patients aged 18 to 64 years presenting with moderate to severe acute pain as defined by an 11-point numeric rating scale (NRS) with an initial score of ≥5 (0 = no pain and 10 = very severe pain). Patients were randomized to receive either 15 mg MSIR combined with 650 mg of Acetaminophen or 10 mg Oxycodone combined with 650 mg Acetaminophen. Patients were assessed at baseline, 30, 45 and 60 min. The primary outcome was reduction in pain at 60 min. Secondary outcomes include drug likeability and adverse events. RESULTS: 80 patients were enrolled in the study (40 per group). Demographic characteristics were similar between the groups (P > 0.05). Mean NRS pain scores at baseline were 8.44 for the MSIR group and 8.53 for the Percocet group (P = 0.788). Mean pain scores decreased over time but remained similar between the groups: 30 min (6.03 vs. 6.43; P = 0.453), 45 min (5.31 vs. 5.48; P = 0.779), and 60 min (4.22 vs. 4.87; P = 0.346). Reduction in mean NRS pain scores were statistically significant from baseline to 30, 45 and 60 min within each group (P < 0.0001 at each time point for both groups). The largest NRS mean difference was from baseline to 60 min: 4.2 (95% CI: 3.43 to 5.01) for MSIR group and 3.61 (95% CI: 2.79 to 4.43) for Percocet group. No clinically significant changes or any serious adverse events were observed in either group. CONCLUSION: MSIR provides similar analgesic efficacy as Percocet for short-term pain relief in the ED, similar rates of nausea/vomiting, and lower rates of likeability of the drug.

Analgesic Efficacy of Intranasal Ketamine Versus Intranasal Fentanyl for Moderate to Severe Pain in Children: A Prospective, Randomized, Double-Blind Study.

PURPOSE: This study aimed to compare analgesic efficacy of intranasal (IN) ketamine to IN fentanyl for moderate to severe pain in children in a pediatric emergency department. METHODS: A prospective, randomized, double-blinded, noninferiority study evaluating children aged 3 to 17 years in a pediatric emergency department with acute moderate to severe pain was conducted. Patients received either 1 mg/kg of IN ketamine or 1.5 µg/kg of IN fentanyl and were evaluated after 10, 20, 30, and 60 minutes. The primary outcome was the degree of pain reduction after 20 minutes. RESULTS: Twenty-two patients were enrolled (11 in each group). Underlying pain conditions represented were musculoskeletal injury (73%) and abdominal pain (27%). At 20 minutes after analgesia, there was no significant difference in pain scores between the fentanyl (median, 2; range, 0-8) and ketamine groups (median, 4; range, 0-7; P = 0.20). The ketamine group showed a significantly greater rate of adverse effects, 73% versus 9% (P = 0.002), and throughout the course of the study period, 7 patients in the ketamine group (64%) group showed some degree of sedation versus no one in the fentanyl group (P = 0.004). CONCLUSIONS: There was insufficient power to support the analgesic noninferiority of IN ketamine at a dose of 1 mg/kg compared with IN fentanyl at a dose of 1.5 µg/kg in children experiencing painful conditions at 20 minutes after administration. Intranasal ketamine was found to be inferior to IN fentanyl in relieving pain at 10 minutes and was found to have significantly greater rates of sedation and dizziness.

Description of Adverse Events in a Cohort of Dance Festival Attendees with Stimulant-Induced Severe Agitation Treated with Dissociative-Dose Ketamine.

BACKGROUND: Emergency clinicians often treat severe agitation resulting from intoxicants, psychiatric illness, and other CNS or systemic diseases. Recreational drugs-especially stimulants-are frequently used by attendees of electronic dance music festivals (EDMFs), and festivalgoers may become dangerously agitated and pose an immediate threat to themselves and others. Although benzodiazepines and antipsychotics are classically used to treat severe agitation, these medications are burdened by safety concerns including respiratory depression and cardiac arrhythmias. The effects of ketamine when used to treat severe agitation in an exclusive cohort of patients with psychostimulant drug-induced toxicity (PDIT) has not previously been reported, and existing literature describes a widely variant safety profile when ketamine is used for sedation of the agitated patient. OBJECTIVE: To describe ketamine's adverse event profile when used to treat patients with severe agitation resulting from PDIT. METHODS: This is a retrospective, observational study enrolling consecutive patients who presented for medical attention at a large outdoor EDMF over a period of eight days on two consecutive weekends in the summer of 2017. The EDMF had an estimated attendance of 40,000 per weekend. A medical tent was set up on-site; patients were managed by a team of EMS providers, nurses and emergency physicians. Medications used, adverse events and the need for repeat dosing were abstracted from prehospital care reports. RESULTS: Over the course of eight days, 1081 of 1186 patients who were evaluated in the medical tent had a recorded chief complaint. 274 of these patients (25.3%) had a chief complaint of altered mental status. In patients presenting with AMS, 68 patients (24.8%) had severe agitation that was treated with dissociative-dose (≥4 mg/kg) intramuscular ketamine. The mean initial dose of ketamine was 308 mg. There were four serious adverse events (5.9%): Two patients (2.9%) had copious hypersalivation treated with atropine, one patient (1.5%) had transient apnea requiring assisted ventilation, and one patient (1.5%) was intubated and transported to the hospital. 42 patients (61.8%) required redosing of calming medications. All patients who received ketamine except the single patient who was intubated and transported were observed in the medical tent until resolution of symptoms and discharged back to the festival. CONCLUSION: In this cohort of festival attendees who developed stimulant-induced severe agitation and were treated with dissociative-dose ketamine, serious adverse events occurred in 5.9% of patients including one patient who was intubated.

Videotaped Unannounced Standardized Patient Encounters to Evaluate Interpersonal and Communication Skills in Emergency Medicine Residents.

BACKGROUND: Communication and interpersonal skills are important for effective patient care but are difficult to measure. Unannounced standardized patient encounters (USPEs) have the benefit of providing a standardized situation and provide a representation of usual care rather than best behavior, while also allowing for video recording without violating patient privacy. We conducted a feasibility pilot study to examine the use of videotaped USPEs in resident education of interpersonal and communication skills and specifically empathy. METHODS: This was a pilot study conducted at an urban community teaching hospital. About 16 first-year emergency medicine engaged in four videotaped USPEs during their normal clinical shifts during 1 academic year. All visible recording equipment was concealed from the residents. The standardized patients completed two assessment forms after each encounter to measure empathy. RESULTS: All 16 residents engaged in four videotaped USPEs for a total of 64 encounters. CONCLUSIONS: We were able to successfully demonstrate the feasibility of using USPEs for assessment of resident interpersonal and communication skills.

Comparison of Oral Ibuprofen and Acetaminophen with Either Analgesic Alone for Pediatric Emergency Department Patients with Acute Pain.

BACKGROUND: Ibuprofen (Motrin; Johnson & Johnson) and acetaminophen (APAP, paracetamol) are the most commonly used analgesics in the pediatric emergency department (ED) for managing a variety of acute traumatic and nontraumatic painful conditions. The multimodal pain management of using a combination of ibuprofen plus acetaminophen has the potential to result in greater analgesia. OBJECTIVE: We compared the analgesic efficacy of a combination of oral ibuprofen plus acetaminophen with either analgesic alone for pediatric ED patients with acute pain. METHODS: We performed a randomized, double-blind superiority trial assessing and comparing the analgesic efficacy of a combination of oral ibuprofen (10 mg/kg dose) plus acetaminophen (15 mg/kg per dose) to either analgesic alone for the treatment of acute traumatic and nontraumatic pain in the pediatric ED. Primary outcomes included a difference in pain scores among the three groups at 60 min. RESULTS: We enrolled 90 patients (30 per group). The difference in mean pain scores at 60 min between acetaminophen and combination groups was 0.30 (95% confidence interval [CI] -0.84 to 1.83); between ibuprofen and combination groups was -0.33 (95% CI -1.47 to 0.80); and between acetaminophen and ibuprofen groups was 0.63 (95% CI -0.54 to 1.81). Reductions in pain scores from baseline to 60 min were similar for all patients in each of the three groups. No adverse events occurred in any group. CONCLUSIONS: We found similar analgesic efficacy of oral ibuprofen and acetaminophen in comparison with each analgesic alone for short-term treatment of acute pain in the pediatric ED, but the trial was underpowered to demonstrate the analgesic superiority of the combination of oral ibuprofen plus acetaminophen in comparison with each analgesic alone.

Does Orally-Administered Radiocontrast Impair Ultrasound Image Quality in Pediatric Patients?

INTRODUCTION: It is commonly assumed that orally-administered radiocontrast material (ORC) preceding abdominal ultrasound (US) performance can obscure image quality and potentially impair diagnostic accuracy when assessing patients with abdominal pain. Due to this concern, ORC administration per protocol for computed tomography (CT) is often delayed until after US performance, potentially contributing to prolonged length of stay in the emergency department (ED) in patients with concern for abdominal pathology. The objective of this study was to evaluate whether early administration of ORC in children with abdominal pain receiving abdominal CT for possible appendicitis obscures subsequent abdominal US image quality. METHODS: We designed a prospective observational study of children <18 years of age presenting to a pediatric ED with abdominal pain who were set to receive ORC prior to obtaining an abdominal CT. These patients received a point-of-care ultrasound (POCUS) of the abdomen to assess the abdominal aorta and right lower quadrant (RLQ) structures (psoas muscle and iliac vessels) pre- and post-ORC administration. Images were compared independently by two blinded emergency US-certified physician-assessors for quality, specifically to determine whether ORC obscured the anatomical structures in question. RESULTS: A total of 17 subjects were enrolled, and each subject had two POCUS studies of the abdomen, one pre- and one post-ORC administration looking to visualize the anatomy of the RLQ and abdominal aorta in both studies. Statistical analysis showed no significant differences in mean values of POCUS image quality scoring by two blinded US-trained physician-assessors for either RLQ structures or abdominal aorta when performed pre- and post-administration of ORC. CONCLUSION: Early ORC administration in children with abdominal pain does not adversely affect image quality of a subsequently performed abdominal US. Patients who may require abdominal CT to determine the etiology of abdominal pain can receive early administration of ORC prior to US performance to help minimize ED length of stay without impairing US diagnostic accuracy.

Administration of Nebulized Ketamine for Managing Acute Pain in the Emergency Department: A Case Series.

Ketamine administration in sub-dissociative doses in the emergency department (ED) results in effective pain relief in patients with acute traumatic and non-traumatic pain, chronic pain, and opioid-tolerant pain. This case series describes five adult ED patients who received nebulized ketamine for predominantly acute traumatic pain. Three patients received nebulized ketamine at 1.5 milligrams per kilogram (mg/kg) dose, one patient at 0.75 mg/kg, and one patient at 1 mg/kg. All five patients experienced a decrease in pain from the baseline up to 120 minutes. The inhalation route of ketamine delivery via breath-actuated nebulizer may have utility for managing pain in the ED.

Urban Emergency Department Response to Measles Outbreak.

In the last year, New York City has had more than 600 confirmed measles cases. For each patient with measles, numerous neonates, unimmunized children, and susceptible adults can be exposed to the highly contagious virus. Working in an emergency department amid such an outbreak presents several challenges because of the crowded nature of the environment, the imperative for rapid identification and isolation of infected patients, and identification of vulnerable individuals who have been in the vicinity when a patient with measles presents. In this report, we discuss our process in navigating these challenges, collaboration with the city's health department, postexposure prophylaxis for individuals exposed in the hospital and the community, and prevention initiatives.
