Principles of Screening for Disease and Health Risk Factors in the Emergency Department.

The emergency department serves as a critical access point to the health system for many patients, especially those with limited resources. Screening for disease or risk factors for poor health outcomes can potentially improve both individual and population health. Screening initiatives should focus on evidence-based strategies and take local epidemiology and ED capacity into consideration. Initiatives should strive for community support and transparency with patients. They should also be financially sustainable for those involved. Screening can identify patients who can then be counseled, provided with prophylaxis or treatment, or referred to external resources. Through screening and intervention, the ED can serve as a vital contributor to individual and population health.

Use of antitussive medications in acute cough in young children.

Acute cough, a common complaint in young children, is often the result of a viral upper respiratory infection. Cough and cold remedies generate billions of dollars in annual sales in the United States, despite a lack of evidence of their efficacy and multiple warnings by the US Food and Drug Administration. The current article begins with the best available evidence for common over-the-counter (OTC) and prescription antitussive remedies in children. The article concludes with a discussion of the pros and cons for the use of antitussives in children with cough. In general, OTC antitussive medications should not be routinely used in children under 2 years of age. In certain cases, antitussives with minimal adverse profile and some evidence of benefit may be recommended after informed counseling.

Between Emergency Department Visits: The Role of Harm Reduction Programs in Mitigating the Harms Associated With Injection Drug Use.

Injection drug use is a major public health problem in the United States. Cocaine, heroin, and methamphetamine are the most commonly injected illicit drugs, whereas opioids are responsible for the majority of overdose fatalities. Although recent emergency department (ED) efforts have focused on expanding capacity for buprenorphine induction for opioid use disorder treatment, the injection of illicit drugs carries specific health risks that require acknowledgment and management, particularly for patients who decline substance use treatment. Harm reduction is a public health approach that aims to reduce the harms associated with a health risk behavior, short of eliminating the behavior itself. Harm-reduction strategies fundamental to emergency medicine include naloxone distribution for opioid overdose. This clinical Review Article examines the specific health complications of injection drug use and reviews the evidence base for 2 interventions effective in reducing morbidity and mortality related to drug injection, irrespective of the specific drug used, that are less well known and infrequently leveraged by emergency medicine clinicians: syringe service programs and supervised injection facilities. In accordance with the recommendations of health authorities such as the Centers for Disease Control and Prevention, emergency clinicians can promote the use of harm-reduction programs in the community to reduce viral transmission and other risks of injection drug use by providing patients with information about and referrals to these programs after injection drug use-related ED visits.

A proposal for selective resuscitation of adult cardiac arrest patients in a pandemic.

Allocation of limited resources in pandemics begs for ethical guidance. The issue of ventilator allocation in pandemics has been reviewed by many medical ethicists, but as localities activate crisis standards of care, and health care workers are infected from patient exposure, the decision to pursue cardiopulmonary resuscitation (CPR) must also be examined to better balance the increased risks to healthcare personnel with the very low resuscitation rates of patients infected with coronavirus disease 2019 (COVID-19). A crisis standard of care that is equitable, transparent, and mindful of both human and physical resources will lessen the impact on society in this era of COVID-19. This paper builds on previous work of ventilator allocation in pandemic crises to propose a literature-based, justice-informed ethical framework for selecting treatment options for CPR. The pandemic affects regions differently over time, so these suggested guidelines may require adaptation to local practice variations.

Consensus Statement on Urgent Care Centers and Retail Clinics in Acute Care of Children.

This article provides recommendations for pediatric readiness, scope of services, competencies, staffing, emergency preparedness, and transfer of care coordination for urgent care centers (UCCs) and retail clinics that provide pediatric care. It also provides general recommendations for the use of telemedicine in these establishments. With continuing increases in wait times and overcrowding in the nation's emergency departments and the mounting challenges in obtaining timely access to primary care providers, a new trend is gaining momentum for the treatment of minor illness and injuries in the form of UCCs and retail clinics. As pediatric visits to these establishments increase, considerations should be made for the type of injury or illnesses that can be safely treated, the required level training and credentials of personnel needed, the proper equipment and resources to specifically care for children, and procedures for safe transfer to a higher level of care, when needed. When used appropriately, UCCs and retail clinics can be valuable and convenient patient care resources.

Effectiveness of SBIRT for Alcohol Use Disorders in the Emergency Department: A Systematic Review.

INTRODUCTION: Alcohol use disorders (AUD) place a significant burden on individuals and society. The emergency department (ED) offers a unique opportunity to address AUD with brief screening tools and early intervention. We undertook a systematic review of the effectiveness of ED brief interventions for patients identified through screening who are at risk for AUD, and the effectiveness of these interventions at reducing alcohol intake and preventing alcohol-related injuries. METHODS: We conducted systematic electronic database searches to include randomized controlled trials of AUD screening, brief intervention, referral, and treatment (SBIRT), from January 1966 to April 2016. Two authors graded and abstracted data from each included paper. RESULTS: We found 35 articles that had direct relevance to the ED with enrolled patients ranging from 12 to 70 years of age. Multiple alcohol screening tools were used to identify patients at risk for AUD. Brief intervention (BI) and brief motivational intervention (BMI) strategies were compared to a control intervention or usual care. Thirteen studies enrolling a total of 5,261 participants reported significant differences between control and intervention groups in their main alcohol-outcome criteria of number of drink days and number of units per drink day. Sixteen studies showed a reduction of alcohol consumption in both the control and intervention groups; of those, seven studies did not identify a significant intervention effect for the main outcome criteria, but nine observed some significant differences between BI and control conditions for specific subgroups (i.e., adolescents and adolescents with prior history of drinking and driving; women 22 years old or younger; low or moderate drinkers); or secondary outcome criteria (e.g. reduction in driving while intoxicated). CONCLUSION: Moderate-quality evidence of targeted use of BI/BMI in the ED showed a small reduction in alcohol use in low or moderate drinkers, a reduction in the negative consequences of use (such as injury), and a decline in ED repeat visits for adults and children 12 years of age and older. BI delivered in the ED appears to have a short-term effect in reducing at-risk drinking.

Molecular alignment in degenerated dissociation channels in strong laser fields.

In this work, we study strong-field molecular alignment in, for the first time, degenerated channels following the same charged states of molecules. By measuring the angular distribution of dissociation fragments from two degenerated N+ + N+ channels of N2, we observe an opposite angular distribution development in these two channels, one expanding and one contracting, when the laser intensity increases. Our further study shows that the expanding channel comes from a nonsequential transition, while the contracting channel involves a sequential transition. We also study the time sequence of the sequential and nonsequential transitions and find that the opposite angular distribution development is due to the different degrees of molecular alignment in these two degenerated channels.

Spectral investigation of higher-order Kerr effects in a tight-focusing geometry.

The role of the Higher-Order Kerr Effects (HOKE) in intensity clamping is experimentally investigated. We fail to observe any evidence of HOKE-based intensity clamping in a tight geometrical focusing experiment. We introduce a polarization-based technique that can distinguish between spectral components from the leading and trailing edges of the pulse. The results of this time-resolved measurement support the ionization theory of intensity clamping.

Physician race/ethnicity predicts successful emergency department analgesia.

UNLABELLED: This study investigated the association between effectiveness of ED pain treatment and race of patients, race of providers, and the concordance of patient and provider race, with a prospective, multicenter study of patients presenting to 1 of 20 US and Canadian EDs with moderate to severe pain. Primary outcome is a 2-point or greater reduction in pain intensity, measured with an 11-point verbal scale, considered the minimum clinically important reduction in pain intensity. A total of 776 patients were enrolled. The sample included 57% female, 44% white, 26% black, and 26% Hispanic. The physician was white in 85% of encounters. Arrival pain score (adjusted odds ratio, 1.14; 95% CI 1.06, 1.24), receipt of any ED analgesia (1.59; 95% CI 1.17, 2.17), and physician nonwhite race (1.68; 95% CI 1.10, 2.55) were significant predictors of clinically significant reduction in pain intensity in multivariate analysis. Nonwhite physicians achieved better pain control without using more analgesics. Future research should explore the determinants of this difference in patient response to pain treatment related to provider race including provider characteristics and training that were not measured in this study. This study provided no evidence supporting an effect of racial concordance on the primary outcome. PERSPECTIVE: This article presents analysis of predictors of clinically important reduction in pain intensity among emergency department patients, finding nonwhite physicians achieving better pain relief with less analgesia. This finding should encourage researchers to investigate elements of the therapeutic relationship that may be enhanced to achieve better pain relief for patients.

Treating headache recurrence after emergency department discharge: a randomized controlled trial of naproxen versus sumatriptan.

STUDY OBJECTIVE: Multiple parenteral medications are used to treat migraine and other acute primary headaches in the emergency department (ED). Regardless of specific headache diagnosis, no medication eliminates the frequent recurrence of primary headache after ED discharge. It is uncertain which medication primary headache patients should be given on discharge from an ED. The aim of this study is to compare the efficacy of oral sumatriptan with naproxen for treatment of post-ED recurrent primary headache. METHODS: This was a randomized, double-blind efficacy trial. We randomized patients to either naproxen 500 mg or sumatriptan 100 mg for headache recurrence after ED discharge. Patients were eligible if they received parenteral therapy for an acute exacerbation of a primary headache in the ED. Patients who met established criteria for migraine without aura were designated a priori as a homogenous subgroup of interest. We followed all patients by telephone 48 hours after ED discharge. The primary endpoint was the between-group difference in change in pain intensity during the 2-hour period after ingestion of either 500 mg naproxen or 100 mg sumatriptan. This difference was measured on a validated 11-point (0 to 10) verbal numeric rating scale (NRS). Satisfaction with the medication and adverse effects were also assessed. Patients who met criteria for migraine without aura were analyzed twice according to a priori design: once as a homogenous subgroup and then again combined with all other primary headaches. RESULTS: Of 410 patients randomized, 383 (93%) had outcome data available for analysis. Two hundred eighty (73%; 95% confidence interval [CI] 68% to 77%) reported headache post-ED discharge and 196 (51%; 95% CI 44% to 58%), including 88 with migraine, took the investigational medication provided to them. The naproxen group improved by a mean of 4.3 NRS points, whereas the sumatriptan group improved by 4.1 points (95% CI for difference of 0.2 points: -0.7 to 1.1 points). Findings were virtually identical among the migraine subset (4.3 versus 4.2 NRS points; 95% CI for difference of 0.1 points: -1.3 to 1.5 points). Seventy-one percent (95% CI 62% to 80%) of naproxen patients and 75% (95% CI 66% to 84%) of sumatriptan patients would want to take the same medication the next time. Adverse effect profiles were also comparable. CONCLUSION: In this trial, nearly three quarters of patients reported headache recurrence within 48 hours of ED discharge. Naproxen 500 mg and sumatriptan 100 mg taken orally relieve post-ED recurrent primary headache and migraine comparably. Clinicians should be guided by medication costs, contraindications, and a patient's previous experience with the medication.

Optimizing emergency department front-end operations.

As administrators evaluate potential approaches to improve cost, quality, and throughput efficiencies in the emergency department (ED), "front-end" operations become an important area of focus. Interventions such as immediate bedding, bedside registration, advanced triage (triage-based care) protocols, physician/practitioner at triage, dedicated "fast track" service line, tracking systems and whiteboards, wireless communication devices, kiosk self check-in, and personal health record technology ("smart cards") have been offered as potential solutions to streamline the front-end processing of ED patients, which becomes crucial during periods of full capacity, crowding, and surges. Although each of these operational improvement strategies has been described in the lay literature, various reports exist in the academic literature about their effect on front-end operations. In this report, we present a review of the current body of academic literature, with the goal of identifying select high-impact front-end operational improvement solutions.

Impact of physician and patient gender on pain management in the emergency department--a multicenter study.

OBJECTIVE: Pain is a complex experience influenced by factors such as age, race, and ethnicity. We conducted a multicenter study to better understand emergency department (ED) pain management practices and examined the influence of patient and provider gender on analgesic administration. DESIGN: Prospective, multicenter, observational study. SETTING: Consecutive patients, >or=8-years-old, presenting with complaints of moderate to severe pain (pain numerical rating scale [NRS] > 3) at 16 U.S. and three Canadian hospitals. OUTCOMES MEASURES: Receipt of any ED analgesic, receipt of opioids, and adequate pain relief in the ED. RESULTS: Eight hundred forty-two patients participated including 56% women. Baseline pain scores were similar in both genders. Analgesic administration rates were not significantly different for female and male patients (63% vs 57%, P = 0.08), although females presenting with severe pain (NRS >or=8) were more likely to receive analgesics (74% vs 64%, P = 0.02). Female physicians were more likely to administer analgesics than male physicians (66% vs 57%, P = 0.009). In logistic regression models, predictors of ED analgesic administration were male physician (odds ratio [OR] = 0.7), arrival pain (OR = 1.3), number of pain assessments (OR = 1.83), and charted follow-up plans (OR = 2.16). With regard to opioid administration, female physicians were more likely to prescribe opioids to females (P = 0.006) while male physicians were more likely to prescribe to males (P = 0.05). In logistic regression models, predictors of opioids administration included male patient gender (OR = 0.58), male patient-physician interaction (OR = 2.58), arrival pain score (OR = 1.28), average pain score (OR = 1.10), and number of pain assessments (OR = 1.5). Pain relief was not impacted by gender. CONCLUSION: Provider gender as opposed to patient gender appears to influence pain management decisions in the ED.

An unusual cause of knee pain discovered at a nurse practitioner clinic.

PURPOSE: To describe an interesting and instructive case of knee pain from nurse practitioner (NP) practice and discuss the epidemiology, pathophysiology, clinical evaluation, and treatment of osteosarcoma. DATA SOURCES: Findings from the history, physical examination, diagnostic testing, and follow-up of the case of an 18-year-old male who first presented with nontraumatic, diffuse left knee pain of 2.5-month duration. CONCLUSIONS: At follow-up, after a trial of conservative treatment, a lesion suspicious for osteosarcoma was seen in the proximal tibia. Osteosarcoma is a rare but dangerous cause of chronic extremity pain, especially in children and adolescents. IMPLICATIONS FOR PRACTICE: NPs must consider malignant bone tumors in the differential diagnosis of traumatic and nontraumatic extremity pain of extended duration, especially in children and adolescents. Thorough, persistent follow-up on recommended tests and referrals is necessary to ensure that important findings are not missed. The care of uninsured patients requires particular attention to cost concerns and access issues.

Disparities in analgesia and opioid prescribing practices for patients with musculoskeletal pain in the emergency department.

INTRODUCTION: Healthy People 2010 seeks to eliminate racial and ethnic disparities in health care; however, disparities due to age and race have been described in emergency department pain treatment. Although pain is a common patient complaint in emergency departments, many people receive no analgesia. This study examined the influence of patient and provider characteristics on ED and discharge analgesia and opioid prescribing practices. METHODS: This descriptive study used chart review of selected variables from ED patients 18 years and older who presented with musculoskeletal pain and were treated by core ED faculty. Logistic regression analyses were performed to determine whether analgesia- and opioid-prescribing disparities existed and were influenced by patient and provider characteristics. RESULTS: A total of 868 patient records were examined. Physician characteristics and wide variation in practice were the only sources of disparities in the prescription of analgesics in the emergency department, but patient characteristics including race, age, chronic pain, and trauma influenced prescription of ED opioids and discharge analgesics. No gender or financial status disparities were found. Fewer opioids and discharge analgesics were prescribed for black patients than for white patients. Younger patients, those with trauma, and those with chronic pain received more opioids and discharge analgesics compared with older patients and those without trauma or chronic pain. Providers who completed emergency medicine residencies and had fewer than 3 years' experience prescribed more analgesics in the emergency department. DISCUSSION: Pain management in our emergency department is widely variable, with some disparities based on patient and physician characteristics. Multicenter prospective studies are needed to validate these findings and examine knowledge and attitude development about pain and its management. Protocols for nurse-initiated analgesia may help improve and standardize ED pain care.

ED predictors of upper gastrointestinal tract bleeding in patients without hematemesis.

OBJECTIVES: In patients with gastrointestinal (GI) tract bleeding, the bleeding source is uncertain in the absence of hematemesis. We sought to identify clinical variables predictive of an upper GI bleeding source. METHODS: This retrospective cohort study involved patients admitted via the ED for GI tract bleeding without hematemesis, who underwent confirmatory testing. We used logistic regression analysis to identify clinical variables independently associated with an upper GI source. RESULTS: Among 325 patients, odds ratios for the strongest predictors were as follows: black stool, 16.6 (95% confidence interval [CI], 7.7-35.7); age less than 50 years, 8.4 (95% CI, 3.2-22.1); and blood urea nitrogen/creatinine ratio 30 or greater, 10.0 (95% CI, 4.0-25.6). Seven (5%) of 151 with none of these factors had an upper GI tract bleed, versus 63 (93%) of 68 with 2 or 3 factors. CONCLUSION: Black stool, age less than 50 years, and blood urea nitrogen/creatinine ratio of 30 or greater independently predict an upper GI tract bleeding source.

Determinants of variation in analgesic and opioid prescribing practice in an emergency department.

OBJECTIVE: Adequate treatment of patients' pain is a top priority for the World Health Organization (WHO), American Medical Association (AMA), and American College of Emergency Physicians (ACEP), but "adequate" is not clearly defined. Most previous studies of emergency department (ED) pain treatments have centered on musculoskeletal pain in terms of rates of analgesia and disparities in treatment based on race and age. This study will examine complaints of pain other than musculoskeletal and will focus on treatment disparities that may result from differences inpatient and physician characteristics. METHODS: This retrospective study is of ED patients 18 years and older with nonmusculoskeletal pain who were seen by ED faculty over a period of eight weeks. Logistic regression and CHI2 tests were performed to quantify effects of doctor, patient, and clinical characteristics on rates of ED analgesia, ED opioids, and analgesic prescriptions at discharge. RESULTS: A total of 1360 patients were included. There was wide variation in the type and frequency of ED analgesia depending on the attending doctor. For example, patients seen by one specific ED doctor were less than half as likely to receive any analgesia and seven times less likely to receive an opioid than those seen by another doctor. Age, race, doctor's training and experience, and whether the patient had chronic pain were important predictors of ED analgesia. There were similar findings for ED opioids and discharge analgesics. CONCLUSION: Pain practices in EDs are highly variable and seem inadequate when measured against the goals of WHO, AMA, and ACEP. Patient age, race, and type of pain and the physician's identity, training, and experience all contribute to practice variation. Further research is needed to identify the causes of these variations, and there is a need to develop interventions to standardize and improve pain assessment and treatment.

Usefulness and validity of diagnostic nasogastric aspiration in patients without hematemesis.

STUDY OBJECTIVE: We estimate the test characteristics of nasogastric aspiration to diagnose upper gastrointestinal tract hemorrhage in patients without hematemesis. METHODS: In this retrospective cohort study, medical records from patients admitted to 2 urban hospitals between 1997 and 2002 for gastrointestinal tract bleeding without hematemesis were reviewed. Positive nasogastric aspiration results were classified by the severity of hemorrhage, and negative results were classified by the presence or absence of bile. The reference standard for nasogastric aspiration was the source of bleeding-upper versus non--upper gastrointestinal tract--from the hospital discharge summary. Confidence intervals (CIs) for proportions and likelihood ratios (LRs) were calculated. RESULTS: Of 333 eligible patients, 235 were offered nasogastric aspiration, and 220 accepted the test. Results of 220 attempts were distributed as follows: negative, 158 (72%), including 9 (4%) with bile; nasogastric aspiration aborted, 13 (6%); and positive, 49 (23%), including 4 (2%) that were strongly positive (> or =450 mL red blood). Test characteristics of nasogastric aspiration to detect upper gastrointestinal tract bleeding in 213 patients with a reference standard diagnosis were as follows: sensitivity 42% (95% CI 32% to 51%), specificity 91% (95% CI 83% to 95%), negative predictive value 64% (95% CI 56% to 71%), and positive predictive value 92% (95% CI 79% to 97%). The nasogastric aspiration accurately predicted the source of bleeding in 66% of patients (95% CI 59% to 72%). The likelihood ratio of a positive nasogastric aspiration was 11 (95% CI 4 to 30), and the likelihood ratio of a negative nasogastric aspiration was 0.6 (95% CI 0.5 to 0.7). CONCLUSION: In patients without hematemesis, a positive nasogastric aspiration, seen in 23%, indicates probable upper gastrointestinal tract bleeding (LR+ 11), but a negative nasogastric aspiration, seen in 72%, provides little information (LR- 0.6).
