A Framework for Quality Assurance of Pediatric Revisits to the Emergency Department.

BACKGROUND: Emergency department return visits significantly impact medical costs and patient flow. A comprehensive approach to understanding these patients is required to identify deficits in care, system level inefficiencies, and improve diagnosis specific management protocols. We aimed to identify factors needed to successfully analyze return visits to explore root causes leading to unplanned returns and inform system-level improvements. METHODS: A multidisciplinary committee collaborated to develop a quality review process for return visits within 72 hours to our pediatric emergency department that were then subsequently admitted to the hospital. The committee developed methodology and a web-based tool for chart review and analysis. RESULTS: Of 197,076 ED visits (159,164 discharged at initial visit), 5390 (3.4%) patients were discharged and represented to the ED within 72 hours and 1658 (1.0%) of those resulted in admission. Using defined criteria, approximately one third (n = 564) of revisits with admission were identified for chart review. Reason for revisit included natural progression of disease (67.6%), new condition or problem (11.2%), diagnostic error (6.9%), and scheduled or planned readmissions (3.5%). All diagnostic errors had not been previously identified by ED leadership. Of the reviewed cases, most were not preventable (84.0%); however, a number of system-level actions resulted from discussion of the potentially preventable revisits. CONCLUSIONS: Seventy-two-hour ED revisits were efficiently and systematically categorized with determination of root causes and preventability. This process resulted in shared provider-level feedback, identifying trends in revisits, and implementation of system-level actions, therefore, encouraging other institutions to adopt a similar process.

Clinical Experience in a Community Setting During Pediatric Emergency Medicine Fellowship Training.

OBJECTIVES: The aim of this study is to explore current community emergency department (ED) experiences available to pediatric emergency medicine (PEM) trainees and estimate the proportion of graduates taking positions that involve working in a community ED setting. METHODS: We conducted an e-mail-based survey among PEM fellowship directors and assistant directors. RESULTS: There were 55 program director respondents (74% response rate). Thirty-one percent of the surveyed PEM fellowship programs provide training exposure to a community ED setting. Twenty-nine percent of the surveyed programs reported that 25% to 49% of graduating trainees accepted positions that involve working in a community hospital ED setting, 13% responded 50% to 74%, and 4% report 75% to 100% from 2012 to 2016. CONCLUSIONS: There is an overall paucity of a dedicated community rotation for PEM trainees, yet many graduates are seeking employment in community-based EDs. Because the need for community-based PEM physicians continues to rise and to adequately prepare the PEM workforce, PEM fellowship training should consider a curriculum that includes community-based ED clinical experiences.

Identification of Optic Nerve Swelling Using Point-of-Care Ocular Ultrasound in Children.

OBJECTIVE: The aim of this study was to determine the feasibility and accuracy of point-of-care (POC) ocular ultrasound (US) when performed by a pediatric emergency medicine (PEM) physician to detect optic nerve abnormalities concerning for swelling, as compared with the fundus examination performed by an ophthalmologist. METHODS: This was a single-center, prospective cohort pilot study of children aged 12 months to 18 years who required optic disc evaluation by an ophthalmologist. Eligible subjects were enrolled from the emergency department, inpatient wards, and neuro-ophthalmology outpatient clinic of an urban, tertiary care children's hospital. Point-of-care ocular US, specifically assessing optic nerve sheath diameter and optic disc elevation, was performed. Findings on US were compared with findings identified by an ophthalmologist on dilated fundus examination. RESULTS: Seventy-six subjects were enrolled; 20 (26%) of 76 had findings concerning for optic nerve swelling diagnosed by an ophthalmologist on fundus examination. Using a sonographic definition for optic nerve swelling of optic nerve sheath diameter greater than 4.5 mm or the presence of optic disc elevation, the sensitivity and specificity were 90% and 55%, respectively. The success rate of POC ocular US was 100%, and the mean time to completion was 8 minutes. For emergency department subjects in whom direct fundus examination was attempted, the PEM physician could visualize the optic disc and assess for swelling in only 40% (14/35) of examinations. CONCLUSIONS: The results of our study suggest that POC ocular US performed by PEM physicians was feasible and determined to be sensitive but nonspecific in the detection of optic nerve swelling. Additional larger studies may determine generalizability to other nonophthalmologist physicians performing POC ocular US.

Reduced Radiation in Children Presenting to the ED With Suspected Ventricular Shunt Complication.

BACKGROUND: Ventricular shunt complications in children can be severe and life-threatening if not identified and treated in a timely manner. Evaluation for shunt obstruction is not without risk, including lifetime cumulative radiation as patients routinely receive computed tomography (CT) scans of the brain and shunt series (multiple radiographs of the skull, neck, chest, and abdomen). METHODS: A multidisciplinary team collaborated to develop a clinical pathway with the goal of standardizing the evaluation and management of patients with suspected shunt complication. The team implemented a low-dose CT scan, specifically tailored for the detection of hydrocephalus and discouraged routine use of shunt series with single-view radiographs used only when specifically indicated. RESULTS: There was a reduction in the average CT effective dose (millisievert) per emergency department (ED) encounter of 50.6% (confidence interval, 46.0-54.9; P ≤ .001) during the intervention period. There was a significant reduction in the number of shunt surveys obtained per ED encounter, from 62.4% to 5.32% (P < .01). There was no significant change in the 72-hour ED revisit rate or CT scan utilization rate after hospital admission. There were no reports of inadequate patient evaluations or serious medical events. CONCLUSIONS: A new clinical pathway has rapidly reduced radiation exposure, both by reducing the radiation dose of CT scans and eliminating or reducing the number of radiographs obtained in the evaluation of patients with ventricular shunts without compromising clinical care.

Lyme Myocarditis Presenting as Chest Pain in an Adolescent Girl.

A previously healthy adolescent girl presented to the emergency department with new onset chest and right upper quadrant abdominal pain. Laboratory studies and imaging were consistent with myocarditis. She developed heart block after admission and required stabilization in the cardiac intensive care unit. Lyme serology returned positive, and her condition was diagnosed as Lyme disease-associated myocarditis.

Identification of optic disc elevation and the crescent sign using point-of-care ocular ultrasound in children.

Point-of-care ocular ultrasound has been used to detect papilledema. In previous studies, investigators have evaluated only optic nerve sheath diameter as a screen for increased intracranial pressure. In this series of 4 children, we demonstrate 2 additional optic nerve abnormalities using point-of-care ocular ultrasound: optic disc elevation and the crescent sign. Assessing the optic nerve for each of these 3 findings may assist the examiner in detecting papilledema.

Effectiveness of physical exam signs for early detection of critical illness in pediatric systemic inflammatory response syndrome.

BACKGROUND: Early detection of compensated pediatric septic shock requires diagnostic tests that are sensitive and specific. Four physical exam signs are recommended for detecting pediatric septic shock prior to hypotension (cold extremities, mental status, capillary refill, peripheral pulse quality); this study tested their ability to detect patients who develop organ dysfunction among a cohort of undifferentiated pediatric systemic inflammatory response syndrome patients. METHODS: A prospective cohort of 239 pediatric emergency department patients <19 years with fever and tachycardia and undergoing phlebotomy were enrolled. Physicians recorded initial physical exams on a standardized form. Abstraction of the medical record determined outcomes including organ dysfunction, intensive care unit stay, serious bacterial infection, and therapies. RESULTS: Organ dysfunction occurred in 13/239 (5.4%) patients. Presence of at least one sign was significantly associated with organ dysfunction (Relative Risk: 2.71, 95% CI: 1.05-6.99), and presence of at least two signs had a Relative Risk = 4.98 (95% CI: 1.82-13.58). The sensitivity of exam findings ranged from 8-54%, specificity from 84-98%. Signs were associated with increased risk of intensive care and fluid bolus, but not with serious bacterial infection, intravenous antibiotics or admission. Altered mental status and peripheral pulse quality were significantly associated with organ dysfunction, while abnormal capillary refill time and presence of cold, mottled extremities were not. CONCLUSIONS: Certain recommended physical exam signs were associated with increased risk of organ dysfunction, a rare outcome in this undifferentiated pediatric population with fever and tachycardia. Sensitivity was low, while specificity was high. Additional research into optimally sensitive and specific diagnostic strategies is needed.

The utility of early lactate testing in undifferentiated pediatric systemic inflammatory response syndrome.

OBJECTIVES: Failure to recognize shock contributes to inadequate early resuscitation in many children with sepsis. Serum lactate levels are used to identify adult patients with septic shock, but physical examination diagnosis alone is recommended in pediatric sepsis. The authors sought to test the utility of lactate testing in pediatric emergency department (ED) patients with systemic inflammatory response syndrome (SIRS). The hypothesis was that early hyperlactatemia (serum lactate ≥ 4.0 mmol/L) would be associated with increased risk of organ dysfunction. METHODS: This was a prospective cohort study of children younger than 19 years with SIRS presenting to a pediatric ED. The primary outcome was organ dysfunction within 24 hours of triage; secondary outcomes included disposition, serious bacterial infection (SBI), treatments, and mortality. Study personnel measured venous lactate level on a point-of-care meter, with clinicians blinded to results, and patients received usual care. RESULTS: A total of 239 subjects were enrolled; 18 had hyperlactatemia. The hyperlactatemia group had a relative risk of 5.5 (95% confidence interval [CI] = 1.9 to 16.0) of developing 24-hour organ dysfunction. As a test for organ dysfunction, hyperlactatemia had a positive likelihood ratio of 5.0, a sensitivity of 31% (95% CI = 13% to 58%), and specificity of 94% (95% CI = 90% to 96%). Subjects with hyperlactatemia were significantly more likely to receive intravenous (IV) antibiotics and fluid boluses; despite increased therapy, they were at significantly increased risk for intensive care unit (ICU) admission and bacterial infection. CONCLUSIONS: Among undifferentiated children with SIRS, early hyperlactatemia is significantly associated with increased risk of organ dysfunction, resuscitative therapies, and critical illness. The addition of serum lactate testing to the currently recommended clinical assessment may improve early identification of pediatric sepsis requiring resuscitation.
