Adolescent alcohol use predicts cannabis use over a three year follow-up period.

Background: Alcohol and cannabis use frequently co-occur, which can result in problems from social and academic impairment to dependence (i.e., alcohol use disorder [AUD] and/or cannabis use disorder [CUD]). The Emergency Department (ED) is an excellent site to identify adolescents with alcohol misuse, conduct a brief intervention, and refer to treatment; however, given time constraints, alcohol use may be the only substance assessed due to its common role in unintentional injury. The current study, a secondary data analysis, assessed the relationship between adolescent alcohol and cannabis use by examining the National Institute of Alcohol Abuse and Alcoholism (NIAAA) two question screen's (2QS) ability to predict future CUD at one, two, and three years post-ED visit. Methods: At baseline, data was collected via tablet self-report surveys from medically and behaviorally stable adolescents 12-17 years old (n = 1,689) treated in 16 pediatric EDs for non-life-threatening injury, illness, or mental health condition. Follow-up surveys were completed via telephone or web-based survey. Logistic regression compared CUD diagnosis odds at one, two, or three-year follow-up between levels constituting a single-level change in baseline risk categorization on the NIAAA 2QS (nondrinker versus low-risk, low- versus moderate-risk, moderate- versus high-risk). Receiver operating characteristic curve methods examined the predictive ability of the baseline NIAAA 2QS cut points for CUD at one, two, or three-year follow-up. Results: Adolescents with low alcohol risk had significantly higher rates of CUD versus nondrinkers (OR range: 1.94-2.76, p < .0001). For low and moderate alcohol risk, there was no difference in CUD rates (OR range: 1.00-1.08). CUD rates were higher in adolescents with high alcohol risk versus moderate risk (OR range: 2.39-4.81, p < .05). Conclusions: Even low levels of baseline alcohol use are associated with risk for a later CUD. The NIAAA 2QS is an appropriate assessment measure to gauge risk for future cannabis use.

Resources for Improving Pediatric Readiness and Quality of Care in Rural Communities and Emergency Departments.

OBJECTIVES: To share the process and products of an 8-year, federally funded grant from the Health Resources and Services Administration Emergency Medical Services for Children program to increase pediatric emergency readiness and quality of care provided in rural communities located within 2 underserved local emergency medical services agencies (LEMSAs) in Northern California. METHODS: In 2 multicounty LEMSAs with 24 receiving hospital emergency departments, we conducted focus groups and interviews with patients and parents, first responders, receiving hospital personnel, and other community stakeholders. From this, we (a regional, urban children's hospital) provided a variety of resources for improving the regionalization and quality of pediatric emergency care provided by prehospital providers and healthcare staff at receiving hospitals in these rural LEMSAs. RESULTS: From this project, we provided resources that included regularly scheduled pediatric-specific training and education programs, pediatric-specific quality improvement initiatives, expansion of telemedicine services, and cultural competency training. We also enhanced community engagement and investment in pediatric readiness. CONCLUSIONS: The resources we provided from our regional, urban children's hospital to 2 rural LEMSAs facilitated improvements in a regionalized system of care for critically ill and injured children. Our shared resources framework can be adapted by other regional children's hospitals to increase readiness and quality of pediatric emergency care in rural and underserved communities and LEMSAs.

Buccally absorbed vs intravenous prochlorperazine for treatment of migraines headaches.

OBJECTIVE: To compare the efficacy of buccally absorbed prochlorperazine (BAP) to intravenous prochlorperazine (IVP) for the abortive treatment of migraine headaches. METHODS: Randomized double-blind trial. Eighty subjects aged 18-65 presenting with migraines to the ED of a safety-net, urban hospital. Subjects were randomized to receive either 6 mg BAP plus 2.25 mL saline IV placebo or 10 mg IVP and buccally absorbed saccharine pill placebo. A 100 mm visual analog scale (VAS) was used to assess pain, nausea, and sedation. Comparisons between groups were analyzed by the Mann-Whitney U test or Fisher's exact test. RESULTS: Eighty subjects were recruited from November 2016 to December 2017; 79 completed the study. Demographics: 60 women and 19 men with a mean age of 38 ± 12.2 years. Initial mean VAS pain scores were similar between groups (BAP: 78.5 ± 19.9 mm vs IVP: 76.9 ± 19.5 mm). The improvement in mean VAS pain scores over 60 minutes for the BAP group was not significantly different from the IVP group (-54.9 ± 29.7 mm vs -66.7 ± 23.2 mm, respectively; P = 0.08). No significant differences were found in rates of nausea or sedation. Nine subjects in the BAP group required rescue treatment compared to 1 in the IVP group. Five subjects reported symptoms consistent with akathisia in the IVP group while no adverse effects were reported in the BAP group. CONCLUSION: Buccally absorbed prochlorperazine (BAP) is an effective, non-invasive treatment for migraine headaches when compared to intravenous prochlorperazine (IVP).

Screening for Adolescent Alcohol Use in the Emergency Department: What Does It Tell Us About Cannabis, Tobacco, and Other Drug Use?

BACKGROUND: The pediatric emergency department (PED) represents an opportune time for alcohol and drug screening. The National Institute of Alcohol Abuse and Alcoholism (NIAAA) recommends a two-question alcohol screen for adolescents as a predictor of alcohol and drug misuse. OBJECTIVE: A multi-site PED study was conducted to determine the association between the NIAAA two-question alcohol screen and adolescent cannabis use disorders (CUD), cigarette smoking, and lifetime use of other drugs. METHODS: Participants included 12-17-year olds (n = 4834) treated in one of 16 participating PEDs. An assessment battery, including the NIAAA two-question screen and other measures of alcohol, tobacco and drug use, was self-administered on a tablet computer. RESULTS: A diagnosis of CUD, lifetime tobacco use or lifetime drug use was predicted by any self-reported alcohol use in the past year, which indicates a classification of moderate risk for middle school ages and low risk for high school ages on the NIAAA two-question screen. Drinking was most strongly predictive of a CUD, somewhat weaker for lifetime tobacco use, and weakest for lifetime drug use. This same pattern held for high school and middle school students and was stronger for high school students over middle school students for all three categories. This association was also found across gender, ethnicity and race. The association was strongest for CUD for high school students, sensitivity 81.7% (95% CI, 77.0, 86.5) and specificity 70.4% (95% CI, 68.6, 72.1). Conclusions/Importance: A single question about past year alcohol use can provide valuable information about other substance use, particularly marijuana.

Emergency Medical Services Utilization by Children.

OBJECTIVE: The aim of this study was to compare demographic and clinical features of children (0-14 years old) who arrived at general emergency departments (EDs) by emergency medical services (EMS) to those who arrived by private vehicles and other means in a rural, 3-county region of northern California. METHODS: We reviewed 507 ED records of children who arrived at EDs by EMS and those who arrived by other means in 2013. We also analyzed prehospital procedures performed on all children transported to an area hospital by EMS. RESULTS: Children arriving by EMS were older (9.0 vs 6.0 years; P < 0.001), more ill (mean Severity Classification Score, 2.9 vs 2.4; P < 0.001), and had longer lengths of stay (3.6 vs 2.1 hours; P < 0.001) compared with children who were transported to the EDs by other means. Children transported by EMS received more subspecialty consultations (18.7% vs 6.9%; P < 0.05) and had more diagnostic testing, including laboratory testing (22.9% vs 10.6%; P < 0.001), radiography (39.7% vs 20.8%; P < 0.001), and computed tomography scans (16.8% vs 2.9%; P < 0.001). Children arriving by EMS were transferred more frequently (8.8% vs 1.6%; P < 0.001) and had higher mean Severity Classification Scores compared with children arriving by other transportation even after adjusting for age and sex (ß = 0.48; 95% confidence interval, 0.35-0.61; P < 0.001). Older children received more prehospital procedures compared with younger children, and these were of greater complexity and a wider spectrum. CONCLUSIONS: Children transported to rural EDs via EMS are more ill and use more medical resources compared with those who arrive to the ED by other means of transportation.

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.

Parent and Nurse Satisfaction Using Pacidose® Oral Medication Delivery Device in the Pediatric Emergency Department: A Pilot Study.

PURPOSE: Administering oral medication to infants is challenging for caregivers, often resulting in incomplete delivery of the intended dose. Pacidose® is an oral medication delivery device that consists of a syringe attached to a tunneled pacifier. This study aimed to determine caregiver and nurse satisfaction and success rate of the Pacidose in the administration of acetaminophen to infants in the pediatric emergency department (ED). DESIGN AND METHODS: This was a prospective trial involving a convenience sample of patients who presented to a pediatric ED between November 2015 and August 2016. Patients younger than 24 months with a physician order for acetaminophen were eligible. Each child received a single dose of acetaminophen delivered by the Pacidose. Nurses, parents, and observing investigators were surveyed with a standardized questionnaire regarding the effectiveness, satisfaction and success rate of Pacidose. RESULTS: 61 patients were enrolled. The median age was 10 months and Pacidose was successful in 77% of patients. Those who required an alternative delivery route were older and no longer used pacifiers. Nurses reported that Pacidose helped administer the medication more easily in 66% of infants and 95% of parents preferred the Pacidose over standard delivery devices. CONCLUSIONS: Pacidose was well tolerated by infants, and both parents and nurses were highly satisfied with this method of administering acetaminophen. PRACTICE IMPLICATIONS: Pacidose is an easy to implement device that can help nurses with oral medication administration. It may have the greatest impact in younger children with recent pacifier use.

Pediatric Emergency Department Study of Cardiac Risk in the Novel Patient (PED SCReeN).

OBJECTIVE: We compare pediatric cardiac risk classification and management recommendations between emergency physicians (EPs) and pediatric cardiologists (PCs) in children with a suspected new cardiac disorder. METHODS: We prospectively compared the work-up, assessment, classification, and disposition of patients aged 0 to 21 years presenting to the emergency department with a potential cardiac etiology in whom an electrocardiogram (ECG) was performed. The criterion standard was a blinded assessment by the PC-electrophysiologist after review of the history, physical examination, ancillary tests, and ECG. RESULTS: In 508 subjects, the median age was 15 years (interquartile range, 11-17 years), with a slight female predominance (281, 55.3%). The most common reasons for obtaining an ECG were: chest pain (158, 31.1%) and syncope, presyncope, or possible seizure (146, 28.7%). The most common auxiliary study was a chest radiograph (432, 85% of subjects). A total of 617 electrocardiographic diagnoses were made by EPs and 984 diagnoses by PCs. Sensitivities and specificities varied by discrete class, but disposition decisions were concordant (home or admission). The EPs were highly accurate for the need for emergent cardiology involvement (area under the curve, 0.89). CONCLUSIONS: The EPs and PCs agreed on the evaluation and disposition of children at either low risk or high risk for an acute cardiac presentation in the emergency department. There was considerable variation in management recommendations in the intermediate risk children needing cardiology outpatient follow-up. We recommend the development and implementation of focused training modules on emergency pediatric cardiology and increased communication with pediatric cardiology to improve patient safety and resource utilization.

The sedation mindset: philosophy, science, and practice.

PURPOSE OF REVIEW: Medicine is evolving. An increasing influx of medically complex patients coupled with diminishing resources set the stage for substantial challenges in providing safe, effective sedation and analgesia for children requiring medical procedures. This review will discuss the essential components of a successful sedation plan outside of the traditional operating room setting. RECENT FINDINGS: As the discipline of sedation has developed, specialty societies have created and updated guidelines, policies, and statements intended to guide their own practice. There is a lack of consensus among them regarding appropriate targeted depths of sedation, monitoring requirements, definitions of adverse events, resuscitation skills required, and appropriate sedatives used. A transparent, collaborative approach is needed to ensure the sharing of expertise and to encourage evidence-based consistency and safety optimization across venues and specialties. SUMMARY: To meet this need, a multidisciplinary strategy is essential in training, performance of procedures outside of the operating room, and care coordination. To deliver safe, effective care, the sedationist must: perform a targeted presedation assessment; optimize the patient and family prior to sedation; tailor the induction and maintenance to the specific child's condition, needs, and procedure; safely recover the child; and provide a safe plan for postsedation care.

Paramedics accurately apply the pediatric assessment triangle to drive management.

OBJECTIVE: To provide an evaluation of the Pediatric Assessment Triangle (PAT) as an assessment tool for use by paramedic providers in the prehospital care of pediatric patients. METHODS: Paramedics from Los Angeles Fire Department (LAFD) received training in the Pediatric Education for Prehospital Professionals (PEPP) course, PAT study procedures, and completed training in applying the PAT to assess children 0-14 years of age. A convenience sample of LAFD paramedic assessments of the pediatric patients transported to 29 participating institutions, over an 18-month period ending July 2010, were eligible for inclusion. Patients who were not transported were excluded from the study, as were the assessments of children with special health-care needs (CSHCN). PAT Study Forms, emergency medical services (EMS) report forms, and emergency department (ED) and hospital charts were entered into a secure database. Two study investigators, blinded to paramedic PAT assessment, reviewed hospital charts and determined the category of illness or injury. RESULTS: A total of 1,552 PAT Study Forms were collected. Overall, 1,168 of the patient (75%) assessments met inclusion criteria, were transported, and had all three data points (PAT Study Form, paramedic EMS report form, and ED/hospital chart) available for analysis. When paramedics used the PAT to identify abnormalities in the three arms of the triangle (PAT Paramedic Pattern) and applied that pattern to form a general impression (PAT Paramedic Impression), the agreement resulted in a κ coefficient of 0.93 [95% CI: 0.91-0.95]. The PAT paramedic impression was congruent with field management, as the majority of patients received consistent interventions with local EMS protocols. The PAT Paramedic Impression for instability demonstrated a sensitivity of 77.4% [95% CI: 72.6-81.5%], a specificity of 90.0% [95% CI: 87.1-91.5%] with a positive likelihood ratio (LR+) of 7.7 [95% CI: 5.9-9.1] and a negative likelihood ratio (LR-) of 0.3 [95% CI: 0.2-0.3]. CONCLUSION: The PAT is a rapid assessment tool that can be readily and reliably used by paramedics in the prehospital setting. The PAT should be used in conjunction with other assessments but can safely drive initial field management.

Heart rate, anxiety and performance of residents during a simulated critical clinical encounter: a pilot study.

BACKGROUND: High-fidelity patient simulation has been praised for its ability to recreate lifelike training conditions. The degree to which high fidelity simulation elicits acute emotional and physiologic stress among participants - and the influence of acute stress on clinical performance in the simulation setting - remain areas of active exploration. We examined the relationship between residents' self-reported anxiety and a proxy of physiologic stress (heart rate) as well as their clinical performance in a simulation exam using a validated assessment of non-technical skills, the Ottawa Crisis Resource Management Global Rating Scale (Ottawa GRS). METHODS: This was a prospective observational cohort study of emergency medicine residents at a single academic center. Participants managed a simulated clinical encounter. Anxiety was assessed using a pre- and post-simulation survey, and continuous cardiac monitoring was performed on each participant during the scenario. Performance in the simulation scenario was graded by faculty raters using a critical actions checklist and the Ottawa GRS instrument. RESULTS: Data collection occurred during the 2011 academic year. Of 40 eligible residents, 34 were included in the analysis. The median baseline heart rate for participants was 70 beats per minute (IQR: 62 - 78). During the simulation, the median maximum heart rate was 140 beats per minute (IQR: 137 - 151). The median minimum heart rate during simulation was 81 beats per minute (IQR: 72 - 92), and mean heart rate was 117 beats per minute (95% CI: 111 - 123). Pre- and post-simulation anxiety scores were equal (mean 3.3, IQR: 3 to 4). The minimum and maximum Overall Ottawa GRS scores were 2.33 and 6.67, respectively. The median Overall score was 5.63 (IQR: 5.0 to 6.0). Of the candidate predictors of Overall performance in a multivariate logistic regression model, only PGY status showed statistical significance (P = 0.02). CONCLUSIONS: Simulation is associated with physiologic stress, and heart rate elevation alone correlates poorly with both perceived stress and performance. Non-technical performance in the simulation setting may be more closely tied to one's level of clinical experience than to perceived or actual stress.

Asthma vital signs at triage: home or admission (ASTHmA).

OBJECTIVES: Commonly used acute asthma scoring systems assess severity of symptoms, whereas other clinical models aim to predict hospitalization; all rely on a measure of response to treatment and use the same criteria across age ranges. This may not reflect a child's changing physiology and response to illness as he or she grows older.This study aimed to find age-specific objective predictors of hospitalization readily known at triage. The goal is to identify rapidly those who will likely need admission regardless of treatment administered or response to aggressive treatment in the emergency department (ED). METHODS: Children between 1 and 18 years of age with a final primary ED International Classification of Diseases, Ninth Revision, diagnosis of asthma or asthma-related spectrum of disease were studied using data from the National Hospital Ambulatory Medical Care Survey. The primary outcome was hospital admission (observation unit, ward, monitored, or pediatric intensive care unit).Triage vital signs, mode of arrival, recent visits, emergency severity index score, as well as demographic and socioeconomic factors were incorporated into age-specific forward-selection multiple logistic regression models. RESULTS: In 2,454,983 ED visits for asthma or reactive airway disease among children 1 to 18 years of age, patterns of vital sign predictors for admission varied by age group. Across all ages, diastolic hypotension at triage was an early, consistent, independent predictor of admission, especially in 1- to 3-year-olds (odds ratio, 6.27; 95% confidence interval, 6.01-6.54) and 3- to 6-year-olds (odds ratio, 17.95; 95% confidence interval, 16.80-19.17). CONCLUSIONS: Age-specific assessment is important in the evaluation of acute asthma or reactive airway exacerbation. Diastolic hypotension may serve as an early warning indicator of severity of disease and need for hospitalization. Variability by age group in vital sign predictor for admission calls for further development or refinement of age-specific asthma assessment tools.

Emergency department presentation of the pediatric systemic inflammatory response syndrome.

OBJECTIVES: The epidemiology of the systemic inflammatory response syndrome (SIRS) in children is poorly understood. We sought to determine national estimates of the incidence of pediatric SIRS and its corresponding clinical etiologies presenting to US emergency departments (EDs) using current definitions. METHODS: We analyzed ED visits by children younger than 18 years from 2007 to 2010 in the National Hospital Ambulatory Medical Care Survey. We used a Bayesian logical framework of prior probability distributions for white blood cell count result to make minimum, moderate, and maximum estimates for pediatric SIRS. RESULTS: Taking the minimum and maximum estimates as modified credible intervals, we report an overall incidence of pediatric SIRS presenting to the ED to be 21.7% (95% modified credible interval, 18.1%-25.4%). The national moderate estimate of pediatric ED visits presenting with SIRS was approximately 6.2 million per year. Children with SIRS and without SIRS had similar baseline characteristics, but SIRS patients were younger (2.9 vs 5.5 years; P < 0.0001), had higher triage acuity (emergent, 9.0 vs 6.3%; P < 0.0001), and were more often admitted (7.0 vs 2.4%; P < 0.0001) than children without SIRS. Based on the moderate estimate, infection was the most common (53%) associated etiology, followed by trauma (10%). Other traditional categories of SIRS were extremely rare. Of note, 35% of children with SIRS did not fall into any of the previously established categories. CONCLUSIONS: Pediatric SIRS is common; its associated clinical contexts include potentially dangerous etiologies; many cases of pediatric SIRS can be recognized in triage; and there is significant heterogeneity in the etiology of pediatric SIRS.

The Pediatric Assessment Triangle: accuracy of its application by nurses in the triage of children.

INTRODUCTION: The Pediatric Assessment Triangle (PAT) is a rapid evaluation tool that establishes a child's clinical status and his or her category of illness to direct initial management priorities. Recently the PAT has been incorporated widely into the pediatric resuscitation curriculum. Although intuitive, its performance characteristics have yet to be quantified. The purpose of this research is to determine quantitatively its accuracy, reliability, and validity as applied by nurses at triage. METHODS: In this prospective observational study, triage nurses performed the PAT on all patients presenting to the pediatric emergency department of an urban teaching hospital. Researchers performed blinded chart review using the physician's initial assessment and final diagnosis as the criterion standard for comparison. RESULTS: A total of 528 children were included in the analysis. Likelihood ratios (LRs) were found for instability and category of pathophysiology using the PAT. Children deemed stable by initial PAT were almost 10 times more likely to be stable on further assessment (LR 0.12, 95% confidence interval [CI] 0.06-0.25). The PAT further specified categories of pathophysiology: respiratory distress (LR+ 4, 95% CI 3.1-4.8), respiratory failure (LR+ 12, 95% CI 4.0-37), shock (LR+ 4.2, 95% CI 3.1-5.6), central nervous system/metabolic disorder (LR+ 7, 95% CI 4.3-11), and cardiopulmonary failure (LR+ 49, 95% CI 20-120). DISCUSSION: The structured assessment of the initial PAT, as performed by nurses in triage, readily and reliably identifies high-acuity pediatric patients and their category of pathophysiology. The PAT is highly predictive of the child's clinical status on further evaluation.

An international, interprofessional investigation of the self-reported podcast listening habits of emergency clinicians: A METRIQ Study.

OBJECTIVES: Podcasts are increasingly being used for medical education. A deeper understanding of usage patterns would inform both producers and researchers of medical podcasts. We aimed to determine how and why podcasts are used by emergency medicine and critical care clinicians. METHODS: An international interprofessional sample (medical students, residents, physicians, nurses, physician assistants, and paramedics) was recruited through direct contact and a multimodal social media (Twitter and Facebook) campaign. Each participant completed a survey outlining how and why they utilize medical podcasts. Recruitment materials included an infographic and study website. RESULTS: 390 participants from 33 countries and 4 professions (medicine, nursing, paramedicine, physician assistant) completed the survey. Participants most frequently listened to medical podcasts to review new literature (75.8%), learn core material (75.1%), and refresh memory (71.8%). The majority (62.6%) were aware of the ability to listen at increased speeds, but most (76.9%) listened at 1.0 x (normal) speed. All but 25 (6.4%) participants concurrently performed other tasks while listening. Driving (72.3%), exercising (39.7%), and completing chores (39.2%) were the most common. A minority of participants used active learning techniques such as pausing, rewinding, and replaying segments of the podcast. Very few listened to podcasts multiple times. CONCLUSIONS: An international cohort of emergency clinicians use medical podcasts predominantly for learning. Their listening habits (rarely employing active learning strategies and frequently performing concurrent tasks) may not support this goal. Further exploration of the impact of these activities on learning from podcasts is warranted.

Subdissociative-dose Ketamine Is Effective for Treating Acute Exacerbations of Chronic Pain.

BACKGROUND: Subdissociative-dose ketamine (SDDK) is used to treat acute pain. We sought to determine if SDDK is effective in relieving acute exacerbations of chronic pain. METHODS: This study was a randomized double-blind placebo-controlled trial conducted May 2017 to June 2018 at a public teaching hospital (ClinicalTrials.gov #NCT02920528). The primary endpoint was a 20-mm decrease on a 100-mm visual analog scale (VAS) at 60 minutes. Power analysis using three groups (0.5 mg/kg ketamine, 0.25 mg/kg ketamine, or placebo infused over 20 minutes) estimated that 96 subjects were needed for 90% power. Inclusion criteria included age > 18 years, chronic pain > 3 months, and acute exacerbation (VAS ≥ 70 mm). Pain, agitation, and sedation were assessed by VAS at baseline and 20, 40, and 60 minutes after initiation of study drug. Telephone follow-up at 24 to 48 hours used a 10-point numeric rating scale for pain. RESULTS: A total of 106 subjects were recruited, with three excluded for baseline pain < 70 mm. After randomization, 35 received 0.5 mg/kg ketamine, 36 received 0.25 mg/kg ketamine, and 35 received placebo. Three subjects receiving 0.5 mg/kg withdrew during the infusion due to adverse effects, and one subject in each group had incomplete data, leaving 97 for analysis. Initial pain scores (91.9 ± 8.9 mm), age (46.5 ± 12.6 years), sex distribution, and types of pain reported were similar. Primary endpoint analysis found that 25 of 30 (83%) improved with 0.5 mg/kg ketamine, 28 of 35 (80%) with 0.25 mg/kg ketamine, and 13 of 32 (41%) with placebo (p = 0.001). More adverse effects occurred in the ketamine groups with one subject in the 0.25 mg/kg group requiring a restraint code for agitation. A total of 89% of subjects were contacted at 24 to 48 hours, and no difference in pain level was detected between groups. CONCLUSION: Ketamine infusions at both 0.5 and 0.25 mg/kg over 20 minutes were effective in treating acute exacerbations of chronic pain but resulted in more adverse effects compared to placebo. Ketamine did not demonstrate longer-term pain control over the next 24 to 48 hours.

Predictive Validity of a 2-Question Alcohol Screen at 1-, 2-, and 3-Year Follow-up.

BACKGROUND: The National Institute on Alcohol Abuse and Alcoholism (NIAAA) 2-question screen is a valid adolescent alcohol screening tool. No studies have examined if this tool predicts future alcohol problems. We conducted a study at 16 pediatric emergency departments to determine the tool's predictive validity for alcohol misuse and alcohol use disorders (AUDs). METHODS: Participants (N = 4834) completed a baseline assessment battery. A subsample of participants completed the battery at 1, 2, and 3 years follow up. RESULTS: Of the 2209 participants assigned to follow-up, 1611 (73%) completed a 1-year follow-up, 1591 (72%) completed a 2-year follow-up, and 1377 (62%) completed a 3-year follow-up. The differences in AUDs between baseline NIAAA screen nondrinkers and lower-risk drinkers were statistically significant at 1 year (P = .0002), 2 years (P <.0001), and 3 years (P = .0005), as were the differences between moderate- and highest-risk drinkers at 1 and 2 years (P < .0001 and P = .0088, respectively) but not at 3 years (P = .0758). The best combined score for sensitivity (86.2% at 1 year, 75.6% at 2 years, and 60.0% at 3 years) and specificity (78.1% at 1 year, 79.2% at 2 years, and 80.0% at 3 years) was achieved by using "lower risk" and higher as a cutoff for the prediction of a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnosis. CONCLUSIONS: The NIAAA 2-question screen can accurately characterize adolescent risk for future AUDs. Future studies are needed to determine optimaluse of the screen.

Most routine laboratory testing of pediatric psychiatric patients in the emergency department is not medically necessary.

We examined the patient characteristics and hospital charges associated with routine medical clearance laboratory screening tests in 1,082 children younger than age eighteen who were brought to the emergency department (ED) for involuntary mental health holds--that is, each patient was brought to the ED to be evaluated for being a danger to him- or herself or to others, for being gravely disabled (unable to meet his or her basic needs due to a mental disorder), or both--from July 2009 to December 2010. Testing was performed on 871 of the children; all patients also received a clinical examination. The median charge for blood and urine testing together was $1,235, and the most frequent ordering pattern was the full comprehensive panel of tests. Of the patients with a nonconcerning clinical examination, 94.3 percent also had clinically nonsignificant test results. When we extrapolated cost savings to the national level, omitting routine screening laboratory tests in the population of pediatric patients presenting to the ED on an involuntary psychiatric hold with nonconcerning clinical exams could represent up to $90 million in savings annually, without reducing the ability to screen for emergency medical conditions. Provider-initiated diagnostic testing instead of routine screening would lead to significantly lower charges to the ED and the patient.
