Online education in a hurry: Delivering pediatric graduate medical education during COVID-19.

In the setting of the coronavirus disease 2019 (COVID-19) pandemic, an emergency hospital-wide eWork policy was enacted at Boston Children's Hospital on March 16, 2020. The number of clinicians on campus was restricted to only essential personnel, guidelines limited clinical care delivery to solely non-elective patients, and strict maximums were placed on the numbers of people allowed to congregate in the same physical space. With this abrupt transition to social distancing and electronic communication, the established approach to educating graduate medical trainees became obsolete overnight. Anticipating significant impact on trainee and faculty professional and personal lives, the importance of adaptive teaching strategies was evident. This document details one approach to redesigning the clinical learning system including a description of the learners and environment, the pedagogical principles that guided the approach, and technological tools used in implementation. Additionally, available literature pertinent to this topic is explored, assessment of the work to date is presented, and suggestions are provided regarding future directions related to online graduate medical education.

Case Report: Comparison of Plasma Metagenomics to Bacterial PCR in a Case of Prosthetic Valve Endocarditis.

Molecular assays for infectious diseases have emerged as important clinical decision-making tools. Unbiased, metagenomic next-generation sequencing is a novel approach holding promise to detect pathogens missed by conventional modalities and to deconvolute admixed nucleic acid sequences from polymicrobial infections in order to identify constituent pathogens. Recent studies have raised concerns about the clinical impact of metagenomics assays and whether their expense is justified. Here, we report a case of polyclonal Streptococcus cristatus endocarditis in a 14-year-old woman with a history of Tetralogy of Fallot. Three sets of admission blood cultures and a commercial plasma metagenomics assay were negative for pathogens, despite persistent vegetations observed on the valve during a later procedure. Multiple strains of Streptococcus cristatus were identified from the explanted valve by amplicon-based 16S rRNA sequencing, confirming the patient had received appropriate antibiotic therapy. This case highlights limitations in the use and interpretation of clinical metagenomics for infectious disease diagnosis and indicates that the clinical yield of these tools may depend upon infection type and anatomic location.

Needles in Hay II: Detecting Cardiac Pathology by the Pediatric Chest Pain Standardized Clinical Assessment and Management Plan.

OBJECTIVES: To determine if patients evaluated using the pediatric chest pain standardized clinical assessment and management plan (SCAMP) in cardiology clinic were later diagnosed with unrecognized cardiac pathology, and to determine if other patients with cardiac pathology not enrolled in the SCAMP would have been identified using the algorithm. STUDY DESIGN: Patients 7-21 years of age, newly diagnosed with hypertrophic or dilated cardiomyopathy, coronary anomalies, pulmonary embolus, pulmonary hypertension, pericarditis, or myocarditis were identified from the Boston Children's Hospital (BCH) cardiac database between July 1, 2010 and December 31, 2012. Patients were cross-referenced to the SCAMP database or retrospectively assessed with the SCAMP algorithm. RESULTS: Among 98 patients with cardiac pathology, 34 (35%) reported chest pain, of whom 10 were diagnosed as outpatients. None of these patients were enrolled in the SCAMP because of alternate chief complaints (n = 4) or referral to BCH for management of the new diagnosis (n = 6). Each of these patients would have had an echocardiogram recommended by retrospective application of the SCAMP algorithm. Two other patients with cardiac pathology were among the 1124 patients assessed by the SCAMP. One patient initially diagnosed with noncardiac chest pain presented 18 months later and was diagnosed with myocarditis as an inpatient. One patient seen initially in the emergency department was subsequently diagnosed with pericarditis as an outpatient. CONCLUSIONS: Patients assessed by the chest pain SCAMP at BCH were not later diagnosed with cardiac pathology that was missed at the initial encounter. Nonenrolled outpatients with cardiac pathology and chest pain would have been successfully identified with the SCAMP algorithm.

Post-mortem genetic testing in a family with long-QT syndrome and hypertrophic cardiomyopathy.

Pediatric sudden unexplained deaths are rare and tragic events that should be evaluated with all the tools available to the medical community. The current state of genetic testing is an excellent resource that improves our ability to diagnose cardiovascular disorders that can lead to sudden cardiac arrest. Post-mortem genetic testing is not typically a covered benefit of health insurance and may not be offered to families in the setting of a negative autopsy. This unusual case includes two separate cardiovascular disorders that highlight the use of genetic testing and its role in diagnosis, screening, and risk stratification. The insurance company's decision to cover post-mortem testing demonstrated both compassion as well as an understanding of the long-term cost effectiveness.

Regional implementation of a pediatric cardiology chest pain guideline using SCAMPs methodology.

BACKGROUND AND OBJECTIVES: Chest pain is a complaint for which children are frequently evaluated. Cardiac causes are rarely found despite expenditure of considerable time and resources. We describe validation throughout New England of a clinical guideline for cost-effective evaluation of pediatric patients first seen by a cardiologist for chest pain using a unique methodology termed the Standardized Clinical Assessment and Management Plans (SCAMPs). METHODS: A total of 1016 ambulatory patients, ages 7 to 21 years initially seen for chest pain at Boston Children's Hospital (BCH) or the New England Congenital Cardiology Association (NECCA) practices, were evaluated by using a SCAMPs chest pain guideline. Findings were analyzed for diagnostic elements, patterns of care, and compliance with the guideline. Results from the NECCA practices were compared with those of Boston Children's Hospital, a regional core academic center. RESULTS: Two patients had chest pain due to a cardiac etiology, 1 with pericarditis and 1 with an anomalous coronary artery origin. Testing performed outside of guideline recommendations demonstrated only incidental findings. Patients returning for persistent symptoms did not have cardiac disease. The pattern of care for the NECCA practices and BCH differed minimally. CONCLUSIONS: By using SCAMPs methodology, we have demonstrated that chest pain in children is rarely caused by heart disease and can be evaluated in the ambulatory setting efficiently and effectively using minimal resources. The methodology can be implemented regionally across a wide range of clinical practice settings and its approach can overcome a number of barriers that often limit clinical practice guideline implementation.

Management of pediatric chest pain using a standardized assessment and management plan.

OBJECTIVES: Chest pain is a common reason for referral to pediatric cardiologists and often leads to an extensive cardiac evaluation. The objective of this study is to describe current management practices in the assessment of pediatric chest pain and to determine whether a standardized care approach could reduce unnecessary testing. PATIENTS AND METHODS: We reviewed all patients, aged 7 to 21 years, presenting to our outpatient pediatric cardiology division in 2009 for evaluation of chest pain. Demographics, clinical characteristics, patient outcomes, and resource use were analyzed. RESULTS: Testing included electrocardiography (ECG) in all 406 patients, echocardiography in 175 (43%), exercise stress testing in 114 (28%), event monitoring in 40 (10%), and Holter monitoring in 30 (7%). A total of 44 (11%) patients had a clinically significant medical or family history, an abnormal cardiac examination, and/or an abnormal ECG. Exertional chest pain was present in 150 (37%) patients. In the entire cohort, a cardiac etiology for chest pain was found in only 5 of 406 (1.2%) patients. Two patients had pericarditits, and 3 had arrhythmias. We developed an algorithm using pertinent history, physical examination, and ECG findings to suggest when additional testing is indicated. Applying the algorithm to this cohort could lead to an ∼20% reduction in echocardiogram and outpatient rhythm monitor use and elimination of exercise stress testing while still capturing all cardiac diagnoses. CONCLUSIONS: Evaluation of pediatric chest pain is often extensive and rarely yields a cardiac etiology. Practice variation and unnecessary resource use remain concerns. Targeted testing can reduce resource use and lead to more cost-effective care.

Rapid-response extracorporeal membrane oxygenation to support cardiopulmonary resuscitation in children with cardiac disease.

BACKGROUND: Survival of children with in-hospital cardiac arrest that does not respond to conventional cardiopulmonary resuscitation (CPR) is poor. We report on survival and early neurological outcomes of children with heart disease supported with rapid-response extracorporeal membrane oxygenation (ECMO) to aid cardiopulmonary resuscitation (ECPR). METHODS AND RESULTS: Children with heart disease supported with ECPR were identified from our ECMO database. Demographic, CPR, and ECMO details associated with mortality were evaluated using multivariable logistic regression. Pediatric overall performance category and pediatric cerebral performance category scores were assigned to ECPR survivors to assess neurological outcomes. There were 180 ECPR runs in 172 patients. Eighty-eight patients (51%) survived to discharge. Survival in patients who underwent ECPR after cardiac surgery (54%) did not differ from nonsurgical patients (46%). Survival did not vary by cardiac diagnosis and CPR duration did not differ between survivors and nonsurvivors. Factors associated with mortality included noncardiac structural or chromosomal abnormalities (OR, 3.2; 95% CI, 1.3-7.9), use of blood-primed ECMO circuit (OR, 7.1; 95% CI, 1.4-36), and arterial pH <7.00 after ECMO deployment (OR, 6.0; 95% CI, 2.1-17.4). Development of end-organ injury on ECMO and longer ECMO duration were associated with increased mortality. Of pediatric overall performance category/pediatric cerebral performance category scores assigned to survivors, 75% had scores ≤2, indicating no to mild neurological injury. CONCLUSIONS: ECPR may promote survival in children with cardiac disease experiencing cardiac arrest unresponsive to conventional CPR with favorable early neurological outcomes. CPR duration was not associated with mortality, whereas patients with metabolic acidosis and noncardiac structural or chromosomal anomalies had higher mortality.

Needles in hay: chest pain as the presenting symptom in children with serious underlying cardiac pathology.

INTRODUCTION: Chest pain in children is common, but rarely heralds serious underlying cardiac pathology. Despite this, the anxiety of missing a potentially life threatening condition creates a large burden of referrals and diagnostic testing. We evaluated patients diagnosed with 1 of 9 serious cardiac diseases and detailed the clinical signs and symptoms of the patients presenting with chest pain. METHODS: Patients diagnosed between the ages of 7 and 21 years from January 2000 to December 2009 at Children's Hospital Boston (CHB) were identified from a database using diagnostic and billing codes for aortic dissection, coronary anomalies, dilated cardiomyopathy, hypertrophic cardiomyopathy, myocarditis, pericarditis, pulmonary embolus, pulmonary hypertension, and Takayasu arteritis. Patients with previously diagnosed congenital or acquired heart disease were excluded. RESULTS: Four hundred eighty-four patients were included and 35% presented with chest pain. Forty-one (24%) of these patients with chest pain were diagnosed in the outpatient cardiology clinic, while the remaining 130 patients (76%) were diagnosed in the emergency department (ED) or inpatient setting. Coronary artery anomalies were the most common diagnosis made in cardiology clinic, and 16 of the 23 (70%) patients with serious coronary anomalies had exercise-induced chest pain. Patients presenting to the ED or inpatient units tended to have other important nonspecific symptoms (35-44%), high-risk past medical histories (12%), physical examination findings (32%), and electrocardiogram (ECG) abnormalities (78%) that heighten clinical suspicion of cardiac disease. CONCLUSIONS: Identifying underlying cardiac pathology in the CHB outpatient cardiology department in patients presenting with chest pain is rare, with only 41 cases over a 10-year period. The presence of exertional chest pain was important in identifying patients with coronary artery anomalies. A detailed history and physical examination, along with a critical review of an ECG, seem to identify those patients with rare diseases who need further diagnostic testing.
