An Operational Framework to Study Diagnostic Errors in Emergency Departments: Findings From A Consensus Panel

OBJECTIVE

To create an operational definition and framework to study diagnostic error in the emergency department setting.

METHODS

We convened a 17-member multidisciplinary panel with expertise in general and pediatric emergency medicine, nursing, patient safety, informatics, cognitive psychology, social sciences, human factors, and risk management and a patient/caregiver advocate. We used a modified nominal group technique to develop a shared understanding to operationally define diagnostic errors in emergency care and modify the National Academies of Sciences, Engineering, and Medicine's conceptual process framework to this setting.

RESULTS

The expert panel defined diagnostic errors as "a divergence from evidence-based processes that increases the risk of poor outcomes despite the availability of sufficient information to provide a timely and accurate explanation of the patient's health problem(s)." Diagnostic processes include tasks related to (a) acuity recognition, information and synthesis, evaluation coordination, and (b) communication with patients/caregivers and other diagnostic team members. The expert panel also modified the National Academies of Sciences, Engineering, and Medicine's diagnostic process framework to incorporate influence of mode of arrival, triage level, and interventions during emergency care and underscored the importance of outcome feedback to emergency department providers to promote learning and improvement related to diagnosis.

CONCLUSIONS

The proposed operational definition and modified diagnostic process framework can potentially inform the development of measurement tools and strategies to study the epidemiology and interventions to improve emergency care diagnosis.

Bilateral Common Iliac Artery Aneurysm, a Case Report

Patient is a 72-year-old male who presented with abdominal pain and hypertension. Through bedside point-of-care ultrasound (POCUS), patient was found to have markedly enlarged bilateral iliac artery aneurysms with signs of impending rupture, which was confirmed on computed tomography (CT) angiogram of the abdomen/pelvis. Patient was immediately taken to the operating room for emergent repair of aneurysm, and was discharged from the hospital the next day. Point-of-care ultrasound is critical in diagnosis and guiding treatment in patients in the emergency department and should be considered in those with undifferentiated abdominal pain.

Topics

Abdominal pain, iliac artery aneurysm, point-of-care ultrasound.

Managing Delirium and Agitation in the Older Emergency Department Patient: The ADEPT Tool

Agitation and delirium are common reasons for older adults to seek care in the emergency department (ED). Providing care for this population in the ED setting can be challenging for emergency physicians. There are several knowledge translation gaps in how to best screen older adults for these conditions and how to manage them. A working group of subject-matter experts convened to develop an easy-to-use, point-of-care tool to assist emergency physicians in the care of these patients. The tool is designed to serve as a resource to address the knowledge translation and implementation gaps that exist in the field. The purpose of this article is present and explain the Assess, Diagnose, Evaluate, Prevent, and Treat tool. Participants were identified with expertise in emergency medicine, geriatric emergency medicine, geriatrics, and psychiatry. Background literature reviews were performed before the in-person meeting in key areas: delirium, dementia, and agitation in older adults. Participants worked electronically before and after an in-person meeting to finalize development of the tool in 2017. Subsequent work was performed electronically in the following months and additional expert review sought. EDs are an important point of care for older adults. Behavioral changes in older adults can be a manifestation of underlying medical problems, mental health concerns, medication adverse effects, substance abuse, or dementia. Five core principles were identified by the group that can help ensure adequate and thorough care for older adults with agitation or delirium: assess, diagnose, evaluate, prevent, and treat. This article provides background for and explains the importance of these principles related to the care of older adults with agitation. It is important for emergency physicians to recognize the spectrum of underlying causes of behavioral changes and have the tools to screen older adults for those causes, and methods to treat the underlying causes and ameliorate their symptoms.

2018 Academic Emergency Medicine Consensus Conference: A Workforce Development Research Agenda for Pediatric Care in the Emergency Department

Each year, more than 30 million children visit U.S. emergency departments (EDs). Although the number of pediatric emergency medicine specialists continues to rise, the vast majority of children are cared for in general EDs outside of children's hospitals. The diverse workforce of care providers for children must possess the knowledge, experience, skills, and systemic support necessary to deliver excellent pediatric emergency care. There is a crucial need to understand the factors that drive the professional development and support systems of this diverse workforce. Through the iterative process culminating with the 2018 Academic Emergency Medicine consensus conference, we have identified five key research themes and prioritized a specific research agenda. These themes represent critical gaps in our understanding of the development and maintenance of the pediatric emergency care workforce and allow for a prioritization of future research efforts. Only by more fully understanding the gaps in workforce needs, and the necessary steps to address these gaps, can outcomes be optimized for children in need of emergency care.

Opportunities for Research in Mental Health Emergencies: Executive Summary and Methodology

Introduction

Despite the ever-increasing numbers of mental health patients presenting to United States emergency departments, there are large gaps in knowledge about acute care of the behavioral health patient. To address this important problem, the Coalition on Psychiatric Emergencies convened a research consensus conference in December 2016 consisting of clinical researchers, clinicians from emergency medicine, psychiatry and psychology, and representatives from governmental agencies and patient advocacy groups.

Methods

Participants used a standardized methodology to select and rank research questions in the order of importance to both researchers and patients.

Results

Three working groups (geriatrics, substance use disorders, and psychosis) reached consensus on 26 questions within their respective domains. These questions are summarized in this document.

Conclusion

The research consensus conference is the first of its kind to include non-clinicians in helping identify knowledge gaps in behavioral emergencies. It is hoped that these questions will prove useful to prioritize future research within the specialty.

A Research Agenda for the Assessment and Management of Acute Behavioral Changes in Elderly Emergency Department Patients

Introduction

Agitation, mental illness, and delirium are common reasons for older adults to seek care in the emergency department (ED). There are significant knowledge gaps in understanding how to best screen older adults for these conditions and how to manage them. In addition, in areas where research has been performed, implementation has been slow. A working group convened to develop a set of high-priority research questions that would advance the understanding of optimal management of older adults with acute behavioral changes in the ED. This manuscript is the product of a breakout session on "Special Populations: Agitation in the Elderly" from the 2016 Coalition on Psychiatric Emergencies' first Research Consensus Conference on Acute Mental Illness.

Methods

Participants were identified with expertise in emergency medicine (EM), geriatric EM, and psychiatry. Background literature reviews were performed prior to the in-person meeting in four key areas: delirium; dementia; substance abuse or withdrawal; and mental illness in older adults. Input was solicited from all participants during the meeting, and questions were iteratively focused and revised, voted on, and ranked by importance.

Results

Fourteen questions were identified by the group with high consensus for their importance related to the care of older adults with agitation in the ED. The questions were grouped into three topic areas: screening and identification; management strategies; and the approach to delirium.

Conclusion

It is important for emergency physicians to recognize the spectrum of underlying causes of behavioral changes, have the tools to screen older adults for those causes, and employ methods to treat the underlying causes and ameliorate their symptoms. Answers to the identified research questions have great potential to improve the care of older adults presenting with behavioral changes.

Pediatric Readiness in the Emergency Department

This is a revision of the previous joint Policy Statement titled "Guidelines for Care of Children in the Emergency Department." Children have unique physical and psychosocial needs that are heightened in the setting of serious or life-threatening emergencies. The majority of children who are ill and injured are brought to community hospital emergency departments (EDs) by virtue of proximity. It is therefore imperative that all EDs have the appropriate resources (medications, equipment, policies, and education) and capable staff to provide effective emergency care for children. In this Policy Statement, we outline the resources necessary for EDs to stand ready to care for children of all ages. These recommendations are consistent with the recommendations of the Institute of Medicine (now called the National Academy of Medicine) in its report "The Future of Emergency Care in the US Health System." Although resources within emergency and trauma care systems vary locally, regionally, and nationally, it is essential that ED staff, administrators, and medical directors seek to meet or exceed these recommendations to ensure that high-quality emergency care is available for all children. These updated recommendations are intended to serve as a resource for clinical and administrative leadership in EDs as they strive to improve their readiness for children of all ages.

Pediatric Medication Safety in the Emergency Department

Pediatric patients cared for in emergency departments (EDs) are at high risk of medication errors for a variety of reasons. A multidisciplinary panel was convened by the Emergency Medical Services for Children program and the American Academy of Pediatrics Committee on Pediatric Emergency Medicine to initiate a discussion on medication safety in the ED. Top opportunities identified to improve medication safety include using kilogram-only weight-based dosing, optimizing computerized physician order entry by using clinical decision support, developing a standard formulary for pediatric patients while limiting variability of medication concentrations, using pharmacist support within EDs, enhancing training of medical professionals, systematizing the dispensing and administration of medications within the ED, and addressing challenges for home medication administration before discharge.

Contrast-enhanced ultrasound findings in soft-tissue lesions: preliminary results

OBJECTIVES

There is currently no widely available, minimally invasive first-level examination that allows physicians to identify soft-tissue lesions that are likely to be malignant. The aim of this pilot study was to explore the potential suitability of dynamic contrast-enhanced ultrasound (DCE-US) for this purpose.

MATERIALS AND METHODS

23 patients were referred to the Veneto Oncological Institute for work-up of superficial soft-tissue lesions. Fourteen lesions were examined with CEUS and enhancement kinetics was analyzed. Subsequently, all lesions were surgically removed and subjected to histological analysis.

RESULTS

The 14 lesions included in the study were histologically classified as malignant (n = 7) or benign (n = 7, including 3 schwannomas). A statistically significant difference between benign and malignant lesions was found in terms of mean times to peak enhancement intensity (p = 0.03) but not mean filling times (FT). When schwannomas were analyzed as a separate group, their mean FT was found to be significantly different from that of the other benign lesions (p = 0.001) and from that of the group comprising other benign lesions as well as malignant lesions (p < 0.005).

CONCLUSIONS

CEUS with analysis of contrast-enhancement kinetics is a relatively low-cost, minimally invasive imaging technique, which appears to be a potentially effective first-level method for identifying suspicious soft-tissue masses.

Frontal Fibrosing Alopecia and Lichen Planopilaris: Clinical, Dermoscopic and Histological Comparison

Frontal fibrosing alopecia (FFA) and lichen planopilaris (LPP) are classified as scarring alopecia. Most authors consider FFA as a clinical variant of LPP on the basis of their similar histological findings; other authors think these pathologies are two different entities. We studied 48 cases of FFA and 86 cases of LPP. Clinical diagnosis was histologically confirmed and all patients underwent videodermoscopy. Moreover, histological study, identifying the main targets of these diseases, results helpful to confirm the diagnosis. FFA selectively affects vellus-like hair in the frontoparietal region and is characterized by a mild skin atrophy and a total loss of follicular openings. In LPP an involvement of total preterminal, terminal and vellus-like follicles, partial or total loss of follicular openings, diffuse hair thinning and twisting, perifollicular erythematous or violaceous papules and mild/severe spinous follicular hyperkeratosis with scalp sclerosis are the features observed. Videodermoscopy improves diagnostic capability, appearing to be helpful to underline FFA and LPP features, confirmed by histologic studies which identify and show different intensity of inflammatory process. Therefore, the two diseases could be considered two different entities on the basis of the different clinical features and the different targets, that can be related to a different pathogenetic mechanism.

Role of psychotherapy in the management of psychiatric diseases

Psychotherapy plays an essential role in the treatment of mental disorders. The use and research of psychological treatment strategies increased drastically over the past decade. The general efficacy of psychotherapy for the treatment of psychiatric diseases is proved and documented in several meta-analyses. Psychotherapy re-searchers have found solutions for acceptable study designs which account for the special character of these interventions and studied the efficacy of psychotherapeutic treatment in more than 1000 intervention trials.Meanwhile evidence-based psychotherapy approaches tailored to a specific diagnosis are dominating the field and question the basis of psychotherapy schools.A new field of research in psychotherapy is the neurobiological basis of mental disorders and the demonstration of neurobiological changes with psycho-therapeutic treatment.

Life cycle of the tick Amblyomma parvum Aragão, 1908 (Acari: Ixodidae) and suitability of domestic hosts under laboratory conditions

Amblyomma parvum is a widespread Neotropical tick found on several domestic animals and is known to harbor a Rickettsia species of yet unknown pathogenicity. However its life cycle on, and suitability of, several of these hosts has not been described. In this work the biology of A. parvum is presented when fed on seven domestic hosts (chicken, dog, rabbit, horse, guinea pig, cattle and goat). The complete life cycle of the tick varied from 96.8 to 102 days. Highest engorgement weight of larvae was from ticks fed on horses and that of nymphs from guinea pigs. Highest larval yield was from guinea pigs and that of nymphs from horses. Engorged female and egg mass weights, yield and conversion of female weight to eggs rates were the highest in dog ticks and the lowest in goat ticks. The highest egg hatching rate was seen in ticks from dogs and the lowest in ticks from cattle. Overall it was seen that dogs were the best host for adult A. parvum ticks, and guinea pigs for immatures. Horses were also shown to be a good host for all tick stages. It can thus be affirmed that A. parvum is a host generalist tick, and its distribution is probably determined by environmental requirements rather than by hosts.

Job market survey of recent pediatric emergency medicine fellowship graduates

OBJECTIVES

The American Academy of Pediatrics Section of Emergency Medicine's Subcommittee on Administration developed a survey tool targeting recent pediatric emergency medicine (PEM) fellowship graduates to assess the current PEM job market in a variety of areas including (1) the new positions accepted, (2) perspectives of fellowship training, and (3) the relationship between PEM and general emergency medicine practice.

METHODS

The 40-question internet-based survey was developed through www.surveymonkey.com. Solicitations to PEM fellowship graduates who completed training between the years 2000 and 2005 were sent via the Section of Emergency Medicine member e-mail list as well as the PEM LISTSERV. Data collection occurred from April to May 2005.

RESULTS

Of 125 survey respondents, 89% completed a 3-year pediatrics residency plus a 3-year PEM fellowship. Offers to graduates of positions with research expectations outnumbered clinical positions, 3:2, with an average of 5 total positions offered per respondent. Thirty-four percent remained at the institution of fellowship graduation, and 71% accepted faculty appointments with medical school affiliation. Seventy percent of work time was spent on clinical duties and 10% on research. Most felt better prepared in the areas of clinical training and teaching than in the areas of research and administration. Additional general emergency medicine exposure was not desired. Half of the respondents felt that a 2-year fellowship program would have met their career goals.

CONCLUSIONS

Recent PEM fellowship graduates felt that job availability was good and were satisfied with their new positions. Respondents perceived better fellowship training in clinical and teaching aspects than in research and administration. New positions were heavily clinical and matched career goals.

Evaluation of a Web-based education program on reducing medication dosing error: a multicenter, randomized controlled trial

CONTEXT

The Broselow Pediatric Resuscitation Tape has been shown to be effective in reducing medication dosing error among pediatric emergency providers. However, the tape has often been used inappropriately or incorrectly.

OBJECTIVE

To evaluate whether a Web-based education program on proper use of the tape could reduce medication dosing errors and time to determine dose.

DESIGN, SETTING, AND PARTICIPANTS

A randomized, controlled trial conducted among 89 pediatric emergency providers from 3 study sites.

INTERVENTION

All study subjects participated in a videotaped simulated stabilization scenario and were then randomly assigned to control or education group. After the intervention, all subjects participated in another simulation.

MAIN OUTCOMES MEASURES

The primary outcomes included dosing deviation from accepted dose range for each medication prescribed and dosing deviation summary, calculated by averaging dosing deviation for all medications. The secondary outcomes included time to determine a dose for each medication prescribed, and dosing time summary; that is, the average time to determine doses for all medications prescribed.

RESULTS

No significant difference was observed in the demographic characteristics of the 2 groups. After the educational intervention, the average (12.6% vs. 24.9%) and median (7.1% vs. 20.1%) dosing deviation summary were much lower in the education group than in the control group. The difference in the median dosing deviation summary between the 2 groups was statistically significant (P = 0.0002). Similar results were observed for the dosing time. The education group demonstrated a lower average (16 vs. 20 seconds) and lower median (15 vs. 18 seconds) dosing time summary than the control group. The difference in the median dosing time summary between the 2 groups was statistically significant (P = 0.02). Analysis of each medication prescribed indicated that the decrease in the dosing deviation and dosing time in the education group was most obvious for several specific medications.

CONCLUSIONS

The Web-based education program on the proper use of the Broselow Pediatric Resuscitation Tape could improve dosing accuracy and reduce dosing time.

Procedural sedation for children with special health care needs

Children with special health care needs represent a growing percentage of pediatric patients treated in all emergency departments. Substantial literature exists concerning the medical treatment of these patients, but there is little written describing the management of procedural sedation or analgesia in this population. This article examines the unique anatomic and physiologic implications of procedural sedation or analgesia management in children with special health care needs.

The potential for errors in children with special health care needs

Children with special health care needs (CSHCN) are at risk for suboptimal treatment when presenting for emergent care to unfamiliar health care providers. Errors in their management may stem from failure to recognize occult conditions, lack of familiarity with rare or complex medical problems, or lack of prior knowledge of baseline physical findings. An emergency information form (EIF) that contains patient-specific information on essential diagnostic and therapeutic interventions may provide a ready personal reference for the emergent care of CSHCN. Coupled with the use of medical identification jewelry and an electronic transmission system, an EIF has the potential to eliminate management errors in the care of these patients.

International Guidelines for Neonatal Resuscitation: An excerpt from the Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care: International Consensus on Science. Contributors and Reviewers for the Neonatal Resuscitation Guidelines

The International Guidelines 2000 Conference on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiac Care (ECC) formulated new evidenced-based recommendations for neonatal resuscitation. These guidelines comprehensively update the last recommendations, published in 1992 after the Fifth National Conference on CPR and ECC. As a result of the evidence evaluation process, significant changes occurred in the recommended management routines for: * Meconium-stained amniotic fluid: If the newly born infant has absent or depressed respirations, heart rate <100 beats per minute (bpm), or poor muscle tone, direct tracheal suctioning should be performed to remove meconium from the airway. * Preventing heat loss: Hyperthermia should be avoided. * Oxygenation and ventilation: 100% oxygen is recommended for assisted ventilation; however, if supplemental oxygen is unavailable, positive-pressure ventilation should be initiated with room air. The laryngeal mask airway may serve as an effective alternative for establishing an airway if bag-mask ventilation is ineffective or attempts at intubation have failed. Exhaled CO(2) detection can be useful in the secondary confirmation of endotracheal intubation. * Chest compressions: Compressions should be administered if the heart rate is absent or remains <60 bpm despite adequate assisted ventilation for 30 seconds. The 2-thumb, encircling-hands method of chest compression is preferred, with a depth of compression one third the anterior-posterior diameter of the chest and sufficient to generate a palpable pulse. * Medications, volume expansion, and vascular access: Epinephrine in a dose of 0.01-0.03 mg/kg (0.1-0.3 mL/kg of 1:10,000 solution) should be administered if the heart rate remains <60 bpm after a minimum of 30 seconds of adequate ventilation and chest compressions. Emergency volume expansion may be accomplished with an isotonic crystalloid solution or O-negative red blood cells; albumin-containing solutions are no longer the fluid of choice for initial volume expansion. Intraosseous access can serve as an alternative route for medications/volume expansion if umbilical or other direct venous access is not readily available. * Noninitiation and discontinuation of resuscitation: There are circumstances (relating to gestational age, birth weight, known underlying condition, lack of response to interventions) in which noninitiation or discontinuation of resuscitation in the delivery room may be appropriate.

The role of emergency physicians in the care of the child in school

Emergency physicians may contribute significantly to the health of children in the school setting. Because children spend the majority of their waking hours in school, they and their adult caretakers experience medical and surgical emergencies on a regular basis. These emergencies include a wide range of problems, such as asthma, seizures, firearms violence, and mass disasters. Additionally, many children in school have limited access to primary care, which increases their risk for medical emergencies. Recent reports from the National Academy of Sciences Institute of Medicine and the Maternal and Child Health Bureau's Emergency Medical Services for Children Program have described the challenges in improving the medical care of children in both the emergency and school settings. The prevalence of school health emergencies provides an opportunity for use of the expertise of emergency physicians. Emergency physicians have an important role in ensuring the proper treatment of emergency medical problems that occur in school. They need to be integrally involved in the development and organization of systems for prevention, initial stabilization, definitive management, and responsible follow-up of medical problems and injuries.

Boomerang babies: emergency department utilization by early discharge neonates

INTRODUCTION

Since 1987 the average length of stay for infants following hospital delivery has decreased 1.8 days. This study was undertaken to evaluate the null hypothesis that early discharge of newborns from nurseries does not result in increased emergency department (ED) utilization during the first 10 days of life. SITE: Thirty community EDs, one university ED.

METHODS

Retrospective review of ED visits of patients two to 10 days of age from 1989 to 1995. The absolute number of ED neonatal visits (NVs) was compared to the total number of ED visits for each year and the ratio of NV/10,000 ED visits determined. The disposition and diagnosis of each patient was noted, and the number and percent of infants admitted to the hospital calculated.

RESULTS

A total of 3.1 million ED visits were reviewed, and 2094 NVs identified. The ratio of NV/10,000 ED visits increased from 4.3 in 1989 to 7.8 in 1995 (P < 0.001), while the average length of stay for deliveries decreased from 2.79 days to 1.85 days. The mean percent of patients admitted from the ED was 10.3% and showed no statistically significant changes over the study period. The majority of visits were for minor medical or educational problems.

CONCLUSION

The null hypothesis is rejected. Early discharge of neonates does result in increased ED utilization. No increase in admission rates for these infants was documented, indicating that patient severity did not increase with ED utilization. There is a need for improved predischarge education and greater access for episodic ambulatory complaints.
