Patient and Visit Characteristics of Pediatric Patients With High-frequency Low-acuity Emergency Department Visits.

INTRODUCTION: Pediatric patients account for a disproportionate number of low-acuity emergency department (ED) visits. The aim of this study is to describe pediatric patient and visit characteristics for high-frequency users for low-acuity visits. METHODS: This was a retrospective cohort study of children presenting to a tertiary care pediatric ED and an affiliated community ED, over a 2-year period, with at least 10 low-acuity visits. Twenty patients with the highest number of visits were classified as "superusers." We analyzed patient data from the larger sample of high-frequency users and visit specific data from superuser visits. IBM SPSS Statistics 25 (SPSS Inc., Chicago, IL) was used to perform descriptive statistics and to summarize demographic and visit specific variables. RESULTS: We identified 181 high-frequency users with a mean number of visits of 14.3 ± 4.3 and a subpopulation of 20 superusers accounting for 434 visits. The majority of high-frequency users (89%) identified as African American and had public insurance (96.1%). Many patients received primary care affiliated with the home institution. In the first year of the study, 50.3% of high-frequency users were infants younger than 1 year at the index visit and 47.4% of superusers were infants at the index visit.Superuser visits were evenly distributed among seasons and the majority of visits occurred during the weekdays (70.7%). The majority of visits were for medical complaints (86.6%) and almost half (47.6%) resulted in some testing (24.9%) or treatment (30.6%); however, only 1.4% resulted in hospital admission. CONCLUSIONS: In our sample, most high-frequency low-acuity ED patients were infants, African American and have public insurance. Many are seen during clinic hours and are paneled at affiliated clinics. Among superusers, the majority of the visits did not require any testing, intervention, or treatment.

Oculocardiac Reflex in a Pediatric Trauma Patient.

We describe the case of a 6-year-old boy who presented to a tertiary care emergency department after a motor vehicle accident with facial trauma and bradycardia. The patient was found to have an orbital floor fracture and inferior rectus muscle entrapment with resulting bradycardia secondary to the oculocardiac reflex. The oculocardiac reflex is an uncommon cause of bradycardia in the setting of trauma but should be considered because it can necessitate surgical intervention.

Utility of the DIVA score for experienced emergency department technicians.

BACKGROUND: The DIVA score is validated for predicting success of the initial attempt at peripheral intravenous insertion by nurses and physicians. A score of 4 or greater is 50% to 60% likely to have a failed first attempt. The study objective was to assess the validity of this score for emergency department technicians. METHODS: This study used a prospective convenience sample of 181 children presenting to the emergency department with intravenous access attempt by one of 29 emergency department technicians. DIVA score, total number of attempts, and median time to successful intravenous cannulation were obtained. RESULTS: Comparing patients with a DIVA score <4 to ≥4, first-time IV placement failure rates were lower (9% [95% CI, 3-24] vs. 41% [95% CI, 33-49]) and median time to IV placement was shorter (75 [interquartile range (IQR) 42-157] vs. 254 [IQR 91-806]) seconds. In patients with scores ≥4, emergency department technicians with ≥5 years of experience were significantly more likely to be successful on the first attempt (OR 2.8; 95% CI, 1.03-7.63). For every year of technician experience, the time to catheter placement, adjusted for DIVA score, decreased by 25 minutes (P≤0.05, R2=0.05). Comparing our receiver operating curve to the derivation study, the areas were similar (0.67 vs. 0.65). CONCLUSIONS: This study provides preliminary evidence for the validity of the DIVA score when applied to IVs placed by emergency department technicians. For patients with high DIVA scores, ≥5 years of IV experience was associated with higher odds of successful first-time IV placement and shorter time to placement. HIGHLIGHTS The difficult intravenous access (DIVA) score may be generalizable to IVs placed by experienced emergency department technicians (EDTs) Higher odds of first-time success in difficult patients with ≥5 years EDT experience Early identification of difficult access may allow for aid of alternative technology Likely first study to evaluate EDTs IV skills in patients with varying DIVA scores.

A Pediatric Case of Persistent Thrombocytopenia in a Patient Who Developed All.

Inherited thrombocytopenia is a topic that was expanded greatly over the last decade and many new genes are being identified. However, inheritance patterns are not always easy to identify because sporadic cases from de novo mutations may in fact be more common. Few studies have assessed the relationship between thrombocytopenia and malignancies, specifically acute lymphoblastic leukemia (ALL). Here we present a pediatric case of persistent thrombocytopenia associated with T-cell ALL. Our patient was initially diagnosed with immune thrombocytopenic purpura with no evidence of malignancy on bone marrow biopsy but presented shortly after with ALL.

Predicting gangrenous cholecystitis.

BACKGROUND: Gangrenous cholecystitis (GC) is often challenging to treat. The objectives of this study were to determine the accuracy of pre-operative diagnosis, to assess the rate of post-cholecystectomy complications and to assess models to predict GC. METHODS: A retrospective single-institution review identified patients undergoing a cholecystectomy. Logistic regression models were used to examine the association of variables with GC and to build risk-assessment models. RESULTS: Of 5812 patients undergoing a cholecystectomy, 2219 had acute, 4837 chronic and 351 GC. Surgeons diagnosed GC pre-operatively in only 9% of cases. Patients with GC had more complications, including bile-duct injury, increased estimated blood loss (EBL) and more frequent open cholecystectomies. In unadjusted analyses, variables significantly associated with GC included: age >45 years, male gender, heart rate (HR) >90, white blood cell count (WBC) >13,000/mm(3), gallbladder wall thickening (GBWT) ≥ 4 mm, pericholecystic fluid (PCCF) and American Society of Anesthesiology (ASA) >2. In adjusted analyses, age, WBC, GBWT and HR, but not gender, PCCF or ASA remained statistically significant. A 5-point scoring system was created: 0 points gave a 2% probability of GC and 5 points a 63% probability. CONCLUSION: Using models can improve a diagnosis of GC pre-operatively. A prediction of GC pre-operatively may allow surgeons to be better prepared for a difficult operation.

Practice patterns and perceptions of influenza testing amongst pediatric urgent care providers.

INTRODUCTION: Despite a sensitivity of 50% to 70% the rapid influenza diagnostic test (RIDT) continues to play an important role in clinical decision-making due to its quick turn-around time, high specificity, relative simplicity of use, and low cost. METHODS: A quantitative study using a web-based survey was distributed to 110 members of the Society of Pediatric Urgent Care aimed to assess RIDT use for diagnosis and management of influenza in outpatient pediatric patients. RESULTS: Responses from 61 providers were received. Forty-two percent (95% CI 29.5-54.5%) of respondents report higher confidence in their diagnosis of influenza with the aid of a positive RIDT. 28% of respondents (95% CI 16.6-39.4%) report a higher likelihood of prescribing antiviral medications to low-risk patients if an RIDT is positive than without laboratory confirmation. CONCLUSION: Most pediatric urgent care respondents reported higher confidence in their diagnosis and higher likelihood of prescribing antivirals with a positive RIDT rather than by clinical symptoms alone.

Developing and Integrating Asynchronous Web-Based Cases for Discussing and Learning Clinical Reasoning: Repeated Cross-sectional Study.

BACKGROUND: Trainees rely on clinical experience to learn clinical reasoning in pediatric emergency medicine (PEM). Outside of clinical experience, graduate medical education provides a handful of explicit activities focused on developing skills in clinical reasoning. OBJECTIVE: In this paper, we describe the development, use, and changing perceptions of a web-based asynchronous tool to facilitate clinical reasoning discussion for PEM providers. METHODS: We created a case-based web-based discussion tool for PEM clinicians and fellows to post and discuss cases. We examined website analytics for site use and collected user survey data over a 3-year period to assess the use and acceptability of the tool. RESULTS: The learning tool had more than 30,000 site visits and 172 case comments for the 55 published cases over 3 years. Self-reported engagement with the learning tool varied inversely with clinical experience in PEM. The tool was relevant to clinical practice and useful for learning PEM for most respondents. The most experienced clinicians were more likely than fellows to report posting commentary, although absolute rate of commentary was low. CONCLUSIONS: An asynchronous method of case presentation and web-based commentary may present an acceptable way to supplement clinical experience and traditional education methods for sharing clinical reasoning.

Under-triage: A New Trigger to Drive Quality Improvement in the Emergency Department.

The emergency department (ED) is a care setting with a high risk for medical error. In collaboration with our nursing colleagues, we identified a new trigger, under-triage, and demonstrated how its implementation could detect and reduce medical errors in the ED. Methods: We defined under-triage as patient visits with an Emergency Severity Index (ESI) score of 4 or 5 (ie, low acuity), and the patient was admitted to the hospital during the same visit. We defined mistriage, or medical error, when nurse-physician dyad reviewers determined that a different ESI level should have been assigned based on the information available at triage. A multidisciplinary team used nominal group technique to build consensus on key drivers and outcome metrics for this new trigger. We randomly selected 267 charts for review utilizing the under-triage trigger. Results: Of the 125,457 patients triaged as level 4 or 5 in 2019 and 2020, 1.1% (n = 1,423) were under-triaged. Of the 267 charts reviewed, 127 were categorized as mistriage, making the under-triage's positive predictive value trigger 48%. Reviews took 2-10 minutes per chart. We identified 10 categories of under-triage. Nine themes emerged, with four specific and measurable action items mapped to process and outcome metrics. Conclusions: We identify a new, feasible ED trigger, under-triage, that identifies medical error with a high positive predictive value. We identify process and outcome metrics and interventions to improve triage for future patients.

Age-related differences pre-, intra-, and postcholecystectomy: A retrospective cohort study of 6,868 patients.

BACKGROUND: Cholecystectomy (CCY) is increasingly performed in older individuals. We sought to examine age-related differences in pre-, intra-, and postoperative factors at a community hospital, using a very large, single-institution cholecystectomy database. MATERIALS AND METHODS: A retrospective review of 6868 patients who underwent CCY from 2001 to 2013 was performed. ROC analysis identified the optimal age cutoff when complications reached a significant inflection point (<55 and ≥55 years). Multiple clinical features and outcomes were measured and compared by age. Logistic regression was used to examine how well a set of covariates predicted postoperative complications. RESULTS: Older patients had significantly higher rates of comorbidities and underwent more extensive preoperative imaging. Intraoperatively, older patients had more blood loss, longer operative times, and more open operations. Postoperatively, older patients experienced more complications and had significantly different pathological findings. While holding age and gender constant, regression analyses showed that preoperative creatinine level, blood loss and history of previous operation were the strongest predictors of complications. The risk for developing complications increased by 2% per year of life. CONCLUSION: Older patients have distinct pre-, intra-, and postoperative characteristics. Their care is more imaging- and cost-intensive. CCY in this population is associated with higher risks, likely due to a combination of comorbidities and age-related worsened physiological status. Pathologic findings are significantly different relative to younger patients. While removing the effect of age, preoperative creatinine levels, blood loss, and history of previous operation predict postoperative complications. Quantifying these differences may help to inform management decisions for older patients.
