Types of diagnostic errors reported by paediatric emergency providers in a global paediatric emergency care research network.

BACKGROUND: Diagnostic errors, reframed as missed opportunities for improving diagnosis (MOIDs), are poorly understood in the paediatric emergency department (ED) setting. We investigated the clinical experience, harm and contributing factors related to MOIDs reported by physicians working in paediatric EDs. METHODS: We developed a web-based survey in which physicians participating in the international Paediatric Emergency Research Network representing five out of six WHO regions, described examples of MOIDs involving their own or a colleague's patients. Respondents provided case summaries and answered questions regarding harm and factors contributing to the event. RESULTS: Of 1594 physicians surveyed, 412 (25.8%) responded (mean age=43 years (SD=9.2), 42.0% female, mean years in practice=12 (SD=9.0)). Patient presentations involving MOIDs had common undifferentiated symptoms at initial presentation, including abdominal pain (21.1%), fever (17.2%) and vomiting (16.5%). Patients were discharged from the ED with commonly reported diagnoses, including acute gastroenteritis (16.7%), viral syndrome (10.2%) and constipation (7.0%). Most reported MOIDs (65%) were detected on ED return visits (46% within 24 hours and 76% within 72 hours). The most common reported MOID was appendicitis (11.4%), followed by brain tumour (4.4%), meningitis (4.4%) and non-accidental trauma (4.1%). More than half (59.1%) of the reported MOIDs involved the patient/parent-provider encounter (eg, misinterpreted/ignored history or an incomplete/inadequate physical examination). Types of MOIDs and contributing factors did not differ significantly between countries. More than half of patients had either moderate (48.7%) or major (10%) harm due to the MOID. CONCLUSIONS: An international cohort of paediatric ED physicians reported several MOIDs, often in children who presented to the ED with common undifferentiated symptoms. Many of these were related to patient/parent-provider interaction factors such as suboptimal history and physical examination. Physicians' personal experiences offer an underexplored source for investigating and mitigating diagnostic errors in the paediatric ED.

Pediatric Head Injuries in Summer Camps.

Summer camps have a unique supervisory environment that may lead to increased head injury risk for children. The epidemiology of head injuries in camps is unclear. We partnered with CampDoc.com to review head injury reports from camp nurses in 2016 from 197 camps in 36 states. A total of 4290 (92%) reports were coded as definite head injuries, 47% (n = 2002) in female campers, with median camper age of 10 years. Head injury severity was coded as mild (94%, n = 4040), moderate (6%, n = 248), or severe (<1%, n = 2). Only 3% (n = 134) were medically evaluated, and 29% (n = 1221) were sports-related. Head injuries were categorized as definite (3%, n = 137) and probable (13%, n = 572) concussions, with 39% (n = 277) being sports-related and 61% (n = 83) of definite concussions incurred by female campers. Summer camps, while an important location of head injury risk, appear to be a safe environment for youth.

More Is More: Drivers of the Increase in Emergency Medicine Residency Applications.

INTRODUCTION: The average number of applications per allopathic applicant to emergency medicine (EM) residency programs in the United States (US) has increased significantly since 2014. This increase in applications has caused a significant burden on both programs and applicants. Our goal in this study was to investigate the drivers of this application increase so as to inform strategies to mitigate the surge. METHODS: An expert panel designed an anonymous, web-based survey, which was distributed to US allopathic senior applicants in the 2017-2018 EM match cycle via the Council of Residency Directors in Emergency Medicine and the Emergency Medicine Residents Association listservs for completion between the rank list certification deadline and release of match results. The survey collected descriptive statistics and factors affecting application decisions. RESULTS: A total of 532 of 1748 (30.4%) US allopathic seniors responded to the survey. Of these respondents, 47.3% felt they had applied to too many programs, 11.8% felt they had applied to too few, and 57.7% felt that their perception of their own competitiveness increased their number of applications. Application behavior of peers going into EM was identified as the largest external factor driving an increase in applications (61.1%), followed by US Medical Licensing Exam scores (46.9%) - the latter was most pronounced in applicants who self-perceived as "less competitive." The most significant limiter of application numbers was the cost of using the Electronic Residency Application Service (34.3%). CONCLUSION: A substantial group of EM applicants identified that they were over-applying to residencies. The largest driver of this process was individual applicant response to the behavior of their peers who were also going into EM. Understanding these motivations may help inform solutions to overapplication.

Chronic Stress and Negative Marital Quality Among Older Couples: Associations With Waist Circumference.

Objective: More than a third of the U.S. population of older adults is obese. The present study tests the Dyadic Biopsychosocial Model of Marriage and Health, which hypothesizes that, among married couples, individual and partner chronic stress predicts increased waist circumference and these links are exacerbated in negative quality marriages. Method: Participants were from the nationally representative longitudinal Health and Retirement Study (HRS). A total of 2,042 married individuals (in 1,098 married couples) completed psychosocial and waist circumference assessments in 2006 and 2010. Analyses examined whether negative marital quality and chronic stress in Wave 1 (2006) were associated with changes in waist circumference over time. Results: Actor-partner interdependence models revealed that greater partner stress, rather than individuals' own reports of stress, was associated with increased waist circumference over time. Higher perceived negative marital quality among husbands and lower negative marital quality among wives exacerbated the positive link between partner stress and waist circumference. Discussion: Consistent with the Dyadic Biopsychosocial Model of Marriage and Health, partner stress has direct associations with waist circumference among couples and this link is moderated by negative marital quality. Thus, dyadic perceptions of stress and negative marital quality are important to consider for understanding marriage and obesity.

Military trainees can accurately measure optic nerve sheath diameter after a brief training session.

BACKGROUND: Identification of elevated intracranial pressure is important following traumatic brain injury. We assessed the feasibility of educating military trainees on accurately obtaining optic nerve sheath diameter measurements using a brief didactic and hands-on training session. Optic nerve sheath diameter is a noninvasive surrogate marker for elevated intracranial pressure, and may be of value in remote military operations, where rapid triage decisions must be made without access to advanced medical equipment. METHODS: Military trainees with minimal ultrasound experience were given a 5-min didactic presentation on optic nerve sheath diameter ultrasound. Trainees practiced optic nerve sheath diameter measurements guided by emergency physician ultrasound experts. Trainees then measured the optic nerve sheath diameter on normal volunteers. Following this, a trained physician measured the optic nerve sheath diameter on the same volunteer as a criterion standard. An average of three measurements was taken. RESULTS: Twenty-three military trainees were enrolled. A mixed design ANOVA was used to compare measurements by trainees to those of physicians, with a mean difference of - 0.6 mm (P = 0.76). A Bland-Altman analysis showed that the degree of bias in optic nerve sheath diameter measures provided by trainees was very small: d = - 0.004 for the right eye and d = - 0.007 for the left eye. CONCLUSION: This study demonstrates that optic nerve sheath diameter measurement can be accurately performed by novice ultrasonographers after a brief training session. If validated, point-of-care optic nerve sheath diameter measurement could impact the triage of injured patients in remote areas.

Feasibility study of advanced focused cardiac measurements within the emergency department.

BACKGROUND: This study aims to compare the increased time needed to perform advanced focused cardiac measurements in the emergency department, including diastolic heart failure evaluation via E/E', and cardiac output with LVOT/VTI. Patients with pertinent cardiopulmonary symptoms in the emergency department had a focused cardiac ultrasound performed by the emergency department ultrasound team. The ability to obtain basic cardiac windows, evaluate for effusion, systolic ejection fraction, and right-sided heart pressures were recorded. Advanced measurements, along with time to obtain all images and the training level of the provider, were recorded. RESULTS: Fifty-three patients were enrolled. Basic focused cardiac windows were able to be obtained in 80% of patients. The average 4-window focused cardiac ultrasound took 4 min and 49 s to perform. Diastolic measurements were able to be obtained in 51% of patients, taking an average of 3 min and 17 s. Cardiac output measurements were able to be obtained in 53% of patients, taking an average of 3 min and 8 s. CONCLUSION: The ability to obtain these images improved with increasing level of training. Performing both cardiac output and diastolic measurements increased the time with bedside ultrasound by 6 min and 25 s, and were able to be obtained in slightly over half of all ED patients.
