Physician workload and practice management in pediatric gastroenterology.

OBJECTIVES: The pediatric gastroenterology workforce has grown in the last few decades. The North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force to understand current pediatric gastroenterology organizations' practice structures. METHODS: 19-item electronic survey was distributed to NASPGHAN members who were clinical or academic division directors. RESULTS: 30% responded to the survey, all directors of academic practices. The median number of clinical sessions per week was seven sessions, and the median individual work relative value unit (wRVU) target for practices was 4000-4500. Healthcare team ratios compared to provider clinical full-time equivalent were reported as the following: Nursing 0.80, medical assistant (MA) 0.29, dietitian 0.29, social worker 0.14, and psychologist 0.13. Regarding compensation, 68.0% were salaried with bonus based on billing or director decision, 28.0% were salaried with no incentive pay, and 4.0% were salaried with a portion at risk if the target was not met, and a bonus was given if the target was met. Most practices participated in a wellness activity with the most common strategies being didactic lectures about physician burnout (80%), annual burnout check-ins (68%), and/or after-hours social activities (60%). CONCLUSIONS: Pediatric gastroenterology practices vary regarding clinical sessions per week and annual wRVU targets with the median at seven sessions per week and an annual goal of 4000-4500 wRVUs, similar to reported national benchmark goals at the 50th percentile. Healthcare teams, including nursing, MAs, dietitians, social workers, and psychologists, had similar ratios of staff to providers for all sizes and types of practices. Most practices are engaging in wellness initiatives.

Implementing Entrustable Professional Activities in Pediatric Fellowships: Facilitating the Process.

BACKGROUND AND OBJECTIVES: Entrustable professional activities (EPAs) will be used for initial certification by the American Board of Pediatrics by 2028. Less than half of pediatric fellowships currently use EPAs for assessment, yet all will need to adopt them. Our objectives were to identify facilitators and barriers to the implementation of EPAs to assess pediatric fellows and to determine fellowship program directors' (FPD) perceptions of EPAs and Milestones. METHODS: We conducted a survey of FPDs from 15 pediatric subspecialties. EPA users were asked about their implementation of EPAs, barriers encountered, and perceptions of EPAs. Nonusers were queried about deterrents to using EPAs. Both groups were asked about potential facilitators of implementation and their perceptions of Milestones. RESULTS: The response rate was 65% (575/883). Of these, 344 (59.8%) were EPA users and 231 (40.2%) were nonusers. Both groups indicated work burden as a barrier to implementation. Nonusers reported more barriers than users (mean [SD]: 7 [3.8] vs 5.8 [3.4], P < .001). Both groups identified training materials and premade assessment forms as facilitators to implementation. Users felt that EPAs were easier to understand than Milestones (89%) and better reflected what it meant to be a practicing subspecialty physician (90%). In contrast, nonusers felt that Milestones were easy to understand (57%) and reflected what it meant to be a practicing subspecialist (58%). CONCLUSIONS: Implementing EPA-based assessment will require a substantial investment by FPDs, facilitated by guidance and easily accessible resources provided by multiple organizations. Perceived barriers to be addressed include FPD time constraints, a need for additional assessment tools, and outcomes data.

Child Health Needs and the Pediatric Gastroenterology Workforce: 2020-2040.

This article is part of an American Board of Pediatrics Foundation-sponsored effort to analyze and forecast the pediatric subspecialty workforce between 2020 and 2040. Herein, an overview of the current pediatric gastroenterology workforce is provided, including demographics, work characteristics, and geographic distribution of practitioners. Brief context is provided on the changing nature of current practice models and the increasing prevalence of some commonly seen disorders. On the basis of a rigorous microsimulation workforce projection model, projected changes from 2020 to 2040 in the number of pediatric gastroenterologists and clinical workforce equivalents in the United States are presented. The article closes with a brief discussion of training, clinical practice, policy, and future workforce research implications of the data presented. This data-driven analysis suggests that the field of pediatric gastroenterology will continue to grow in scope and complexity, propelled by scientific advances and the increasing prevalence of many disorders relevant to the discipline. The workforce is projected to double by 2040, a growth rate faster than most other pediatric subspecialties. Disparities in care related to geography, race, and ethnicity are among the most significant challenges for the years ahead. Changes to training and education, incentives to meet the needs of underserved populations, and new multidisciplinary models for health care delivery will be necessary to optimally meet the volume, diversity, and complexity of children with gastroenterological diseases in the years ahead.

Relationship between epa level of supervision with their associated subcompetency milestone levels in pediatric fellow assessment.

BACKGROUND: Entrustable Professional Activities (EPA) and competencies represent components of a competency-based education framework. EPAs are assessed based on the level of supervision (LOS) necessary to perform the activity safely and effectively. The broad competencies, broken down into narrower subcompetencies, are assessed using milestones, observable behaviors of one's abilities along a developmental spectrum. Integration of the two methods, accomplished by mapping the most relevant subcompetencies to each EPA, may provide a cross check between the two forms of assessment and uncover those subcompetencies that have the greatest influence on the EPA assessment. OBJECTIVES: We hypothesized that 1) there would be a strong correlation between EPA LOS ratings with the milestone levels for the subcompetencies mapped to the EPA; 2) some subcompetencies would be more critical in determining entrustment decisions than others, and 3) the correlation would be weaker if the analysis included only milestones reported to the Accreditation Council for Graduate Medical Education (ACGME). METHODS: In fall 2014 and spring 2015, the Subspecialty Pediatrics Investigator Network asked Clinical Competency Committees to assign milestone levels to each trainee enrolled in a pediatric fellowship for all subcompetencies mapped to 6 Common Pediatric Subspecialty EPAs as well as provide a rating for each EPA based upon a 5-point LOS scale. RESULTS: One-thousand forty fellows were assessed in fall and 1048 in spring, representing about 27% of all fellows. For each EPA and in both periods, the average milestone level was highly correlated with LOS (rho range 0.59-0.74; p < 0.001). Correlations were similar when using a weighted versus unweighted milestone score or using only the ACGME reported milestones (p > 0.05). CONCLUSIONS: We found a strong relationship between milestone level and EPA LOS rating but no difference if the subcompetencies were weighted, or if only milestones reported to the ACGME were used. Our results suggest that representative behaviors needed to effectively perform the EPA, such as key subcompetencies and milestones, allow for future language adaptations while still supporting the current model of assessment. In addition, these data provide additional validity evidence for using these complementary tools in building a program of assessment.

The Use of the Perioperative Nutrition Score in Postoperative Pediatric Inflammatory Bowel Disease Patients.

BACKGROUND AND OBJECTIVES: Preoperative malnutrition is associated with increased postoperative morbidity. The perioperative nutrition score (PONS) was developed to identify patients at risk of malnutrition. We sought to assess the correlation between preoperative PONS and postoperative outcomes in pediatric inflammatory bowel disease (IBD) patients. METHODS: We performed a retrospective cohort study of IBD patients, less than 21 years of age, who underwent elective bowel resection between June 2018 and November 2021. Patients were divided based upon whether they met PONS criteria. The primary outcome was postoperative surgical site infections. RESULTS: 96 patients were included. Sixty-one patients (64%) met at least one PONS criteria, while 35 patients (36%) met none. PONS positive patients more frequently received preoperative TPN supplementation (p < .001). There was no difference in preoperative oral nutritional supplementation between groups. Patients that screened positive for PONS had a longer hospital stay (p = .002), more readmissions (p = .029), and more surgical site infections (p = .002). CONCLUSIONS: Our data highlight the prevalence of malnutrition in the pediatric IBD population. Patients who screened positive had worse postoperative outcomes. Further, very few of these patients received preoperative optimization with oral nutritional supplementation. There is a need for standardization of nutritional evaluation to improve preoperative nutritional status and postoperative outcomes. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Retrospective Cohort.

Physician Burnout in Pediatric Gastroenterology.

OBJECTIVES: Physicians are prone to burnout which can negatively affect the quality of patient care and lead to medical errors. Burnout can also affect physicians by impacting their personal relationships, their sense of career fulfillment, and job satisfaction. The North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a taskforce to investigate burnout among pediatric gastroenterologists. METHODS: A 35-item electronic survey was developed to collect demographic and practice information and characterize the well-being of pediatric gastroenterologists. Burnout was assessed employing 2 single-item measures adapted from the Maslach Burnout Inventory. The survey was distributed to NASPGHAN members 3 times from February 2020 to March 2020. Descriptive statistics, Chi-square, and Fisher exact tests were used. RESULTS: One thousand seven hundred ninety-one e-mails were successfully sent and 408 participants (22.7%) returned surveys. A total of 28.8% reported high risk for emotional exhaustion, 17.5% reported high risk for depersonalization, and 33% reported overall burnout. Participants 44 years of age or younger reported significantly more burnout than those 45 years and older ( P = 0.018). Contributors to high burnout identified included increased patient load/demands, insufficient nursing support, electronic health record (EHR) use, insufficient administrative staff, excessive on-call coverage, and more complex patients. Forty-four percent reported not having enough time for their personal life including family. A total of 16.2% of participants reported that they would not choose to be a pediatric gastroenterologist again. CONCLUSIONS: Pediatric gastroenterologists are at risk for emotional exhaustion, depersonalization, and overall burnout. Strategies to prevent physician burnout should be implemented as soon as feasibly possible to improve individual mental health and patient care.

Single-Center Retrospective Review of the Presentation and Initial Care of Esophageal Button Battery Impactions 2007-2020.

OBJECTIVE: The aims of this study were to characterize the patient population and initial presentation and care of esophageal button battery ingestion and provide descriptive data including factors affecting accurate diagnosis, duration of battery exposure, and battery removal. METHODS: This was a retrospective cohort study from 2007 to 2020 at a single-center, large-volume, urban academic pediatric hospital system. Included participants were children 6 months to 18 years old who underwent removal of an esophageal button battery impaction at our institution. RESULTS: Our cohort comprised 63 patients; ages ranged from 7 to 87 months with a median of 27 months. Median button battery size was 2.12 cm with 59% lodged in the proximal esophagus. A prolonged impaction, greater than 12 hours, occurred in 46% of patients. Risk ratio analysis demonstrated that lack of caregiver suspicion of ingestion was associated with prolonged impaction (risk ratio, 3.39; confidence interval, 2.15-5.34). Misdiagnosis of button battery ingestion occurred in 10% of cases. The majority of patients, 87%, required transfer from a referring facility with a median total distance of 37 miles (range, 1.4-160 miles) from home to facility where battery was removed. CONCLUSION AND RELEVANCE: This study describes the initial presentation and care of a large cohort of pediatric esophageal button battery ingestion. It emphasizes the continued need for primary prevention, prompt identification, and removal of these batteries. There are many challenges in caring for these patients involving multiple pediatric disciplines, and guidelines encompassing a multidisciplinary approach would be beneficial.

Targeted Assessment of Mucosal Immune Gene Expression Predicts Clinical Outcomes in Children with Ulcerative Colitis.

BACKGROUND AND AIMS: We aimed to determine whether a targeted gene expression panel could predict clinical outcomes in paediatric ulcerative colitis [UC] and investigated putative pathogenic roles of predictive genes. METHODS: In total, 313 rectal RNA samples from a cohort of newly diagnosed paediatric UC patients (PROTECT) were analysed by a real-time PCR microfluidic array for expression of type 1, 2 and 17 inflammation genes. Associations between expression and clinical outcomes were assessed by logistic regression. Identified prognostic markers were further analysed using existing RNA sequencing (RNA-seq) data sets and tissue immunostaining. RESULTS: IL13RA2 was associated with a lower likelihood of corticosteroid-free remission (CSFR) on mesalamine at week 52 (p = .002). A model including IL13RA2 and only baseline clinical parameters was as accurate as an established clinical model, which requires week 4 remission status. RORC was associated with a lower likelihood of colectomy by week 52. A model including RORC and PUCAI predicted colectomy by 52 weeks (area under the receiver operating characteristic curve 0.71). Bulk RNA-seq identified IL13RA2 and RORC as hub genes within UC outcome-associated expression networks related to extracellular matrix and innate immune response, and lipid metabolism and microvillus assembly, respectively. Adult UC single-cell RNA-seq data revealed IL13RA2 and RORC co-expressed genes were localized to inflammatory fibroblasts and undifferentiated epithelial cells, respectively, which was supported by protein immunostaining. CONCLUSION: Targeted assessment of rectal mucosal immune gene expression predicts 52-week CSFR in treatment-naïve paediatric UC patients. Further exploration of IL-13Rɑ2 as a therapeutic target in UC and future studies of the epithelial-specific role of RORC in UC pathogenesis are warranted.

Lessons Learned from OpenNotes Learning Mode and Subsequent Implementation across a Pediatric Health System.

BACKGROUND: The 21st Century Cures Act has accelerated adoption of OpenNotes, providing new opportunities for patient and family engagement in their care. However, these regulations present new challenges, particularly for pediatric health systems aiming to improve information sharing while minimizing risks associated with adolescent confidentiality and safety. OBJECTIVE: Describe lessons learned preparing for OpenNotes across a pediatric health system during a 4-month trial period (referred to as "Learning Mode") in which clinical notes were not shared by default but decision support was present describing the upcoming change and physicians could request feedback on complex cases from a multidisciplinary team. METHODS: During Learning Mode (December 3, 2020-March 9, 2021), implementation included (1) educational text at the top of commonly used note types indicating that notes would soon be shared and providing guidance, (2) a new confidential note type, and (3) a mechanism for physicians to elicit feedback from a multidisciplinary OpenNotes working group for complex cases with questions related to OpenNotes. The working group reviewed lessons learned from this period, as well as implementation of OpenNotes from March 10, 2021 to June 30, 2021. RESULTS: During Learning Mode, 779 confidential notes were written across the system. The working group provided feedback on 14 complex cases and also reviewed 7 randomly selected confidential notes. The proportion of physician notes shared with patients increased from 1.3% to 88.4% after default sharing of notes to the patient portal. Key lessons learned included (1) sensitive information was often present in autopopulated elements, differential diagnoses, and supervising physician note attestations; and (2) incorrect reasons were often selected by clinicians for withholding notes but this accuracy improved with new designs. CONCLUSION: While OpenNotes provides an unprecedented opportunity to engage pediatric patients and their families, targeted education and electronic health record designs are needed to mitigate potential harms of inappropriate disclosures.

Evolving Clinical Care in Esophageal Button Batteries: Impact of Expert-Opinion Guideline Adoption and Continued Gaps in Care.

BACKGROUND/OBJECTIVES: Esophageal button battery impactions (BBI) in children pose a significant danger to children. Although there are expert-opinion guidelines to help manage this population, few studies detail the impact of guidelines on the clinical care of these patients. With this study, we aimed to describe the care of these patients before and following adoption of guidelines at a single center. METHODS: Retrospective cohort study of patients with esophageal BBI at a single center, large volume, urban academic pediatric hospital system before adoption of expert-opinion guidelines (2007-2017) and following adoption (2018-2020). RESULTS: Cohort was comprised of 31 patients before adoption and 32 patients following adoption of guidelines. Patient characteristics did not differ between groups. After 2018, significantly more patients received acetic acid irrigation, initial cross-sectional imaging, and serial cross-sectional imaging. There was also an increase in intensive care unit (ICU) stays, number of intubations, nil per os time, and hospital length of stay. There was no difference in patient outcomes. CONCLUSION: This study describes a large cohort of pediatric esophageal BBI before and following adoption of guidelines. Findings detail increased adherence to guidelines resulting in more cross-sectional imaging which led to ICU stays, longer length of stays, and more nil per os time. This study emphasizes the need for multi-disciplinary guidelines as well as further multi-institutional study.

Clinical and Host Biological Factors Predict Colectomy Risk in Children Newly Diagnosed With Ulcerative Colitis.

BACKGROUND: Develop a clinical and biological predictive model for colectomy risk in children newly diagnosed with ulcerative colitis (UC). METHODS: This was a multicenter inception cohort study of children (ages 4-17 years) newly diagnosed with UC treated with standardized initial regimens of mesalamine or corticosteroids (CS) depending upon initial disease severity. Therapy escalation to immunomodulators or infliximab was based on predetermined criteria. Patients were phenotyped by clinical activity per the Pediatric Ulcerative Colitis Activity Index (PUCAI), disease extent, endoscopic/histologic severity, and laboratory markers. In addition, RNA sequencing defined pretreatment rectal gene expression and high density DNA genotyping by the Affymetrix UK Biobank Axiom Array. Coprimary outcomes were colectomy over 3 years and time to colectomy. Generalized linear models, Cox proportional hazards multivariate regression modeling, and Kaplan-Meier plots were used. RESULTS: Four hundred twenty-eight patients (mean age 13 years) started initial theapy with mesalamine (n = 136), oral CS (n = 144), or intravenous CS (n = 148). Twenty-five (6%) underwent colectomy at ≤1 year, 33 (9%) at ≤2 years, and 35 (13%) at ≤3 years. Further, 32/35 patients who had colectomy failed infliximab. An initial PUCAI ≥ 65 was highly associated with colectomy (P = 0.0001). A logistic regression model predicting colectomy using the PUCAI, hemoglobin, and erythrocyte sedimentation rate had a receiver operating characteristic area under the curve of 0.78 (95% confidence interval [0.73, 0.84]). Addition of a pretreatment rectal gene expression panel reflecting activation of the innate immune system and response to external stimuli and bacteria to the clinical model improved the receiver operating characteristic area under the curve to 0.87 (95% confidence interval [0.82, 0.91]). CONCLUSIONS: A small group of children newly diagnosed with severe UC still require colectomy despite current therapies. Our gene signature observations suggest additional targets for management of those patients not responding to current medical therapies.

Early Change in Fecal Calprotectin Predicts One-Year Outcome in Children Newly Diagnosed With Ulcerative Colitis.

INTRODUCTION: While fecal calprotectin (FC) is used to assess disease activity in ulcerative colitis (UC) there are little data concerning the role of serial FC levels at diagnosis in predicting clinical course. We sought to determine whether FC at diagnosis or early change following therapy predicts clinical outcomes in pediatric UC.Methods: Children with newly diagnosed UC were treated with standardized regimens of mesalamine or corticosteroids (CS). CS tapering and escalation to additional therapy or colectomy were by protocol. Patients with baseline or week 4 or week 12 FC levels were included in the analysis. Our primary outcome was CS-free remission on mesalamine at week 52. We compared the prognostic value of a baseline FC as well as a change in FC by week 4 or week 12 in predicting clinical outcomes. RESULTS: The study included 352 children (113 initial mesalamine, 239 initial CS, mean age 12.6 years) with UC. At Week 52, 135 (38.3%), 84 (23.8%), and 19 (5.4%) children achieved CS-free remission, needed anti-tumor necrosis factor therapy or had colectomy respectively. Baseline FC was not associated with CS-free remission at week 52. However, both week 4 (odds ratio [OR] 0.95, 95% confidence interval [CI] 0.901.00) and week 12 FC levels (OR 0.91, 95% CI 0.87-0.96) were associated with outcomes, with the latter having a stronger association with CS-free remission. Patients with a >75% decrease by 12 weeks, had a 3-fold increased likelihood of CS-free remission at 1 year. DISCUSSION: Longitudinal changes in FC may predict 1 year outcomes better than values at diagnosis in children with a new diagnosis of UC.

Fellow Entrustment for the Common Pediatric Subspecialty Entrustable Professional Activities Across Subspecialties.

OBJECTIVE: To determine the relationship between level of supervision (LOS) ratings for the Common Pediatric Subspecialty Entrustable Professional Activities (EPAs) with their associated subcompetency milestones across subspecialties and by fellowship training year. METHODS: Clinical Competency Committees (CCCs) in 14 pediatric subspecialties submitted LOS ratings for 6 Common Subspecialty EPAs and subcompetency milestone levels mapped to these EPAs. We examined associations between these subcompetency milestone levels and LOS ratings across subspecialty training year by fitting per-EPA linear mixed effects models, regressing LOS rating on milestone level and on training year. RESULTS: CCCs from 211 pediatric fellowship programs provided data for 369 first, 336 second, and 331 third year fellows. Mean subcompetency milestone levels increased similarly among subspecialties for most EPAs compared with the reference, Adolescent Medicine. Mean subcompetency milestones mapped to each EPA and mean EPA LOS ratings generally increased by training year across all subspecialties. CONCLUSIONS: Subcompetency milestones levels mapped to each Common Subspecialty EPA and the EPA LOS ratings increase similarly across subspecialties and by training year, providing validity evidence for using EPA LOS to assess pediatric subspecialty trainee performance. This study supports the development of tools to facilitated the CCC evaluation process across all pediatric subspecialties.

Achieving Entrustable Professional Activities During Fellowship.

BACKGROUND AND OBJECTIVES: Entrustable Professional Activities (EPAs) were developed to assess pediatric fellows. We previously showed that fellowship program directors (FPDs) may graduate fellows who still require supervision. How this compares with their expectations for entrustment of practicing subspecialists is unknown. METHODS: We surveyed US FPDs in 14 pediatric subspecialties through the Subspecialty Pediatrics Investigator Network between April and August 2017. For each of 7 common pediatric subspecialty EPAs, we compared the minimum level of supervision that FPDs required for graduation with the level they expected of subspecialists for safe and effective practice using the Friedman rank sum test and paired t test. We compared differences between subspecialties using linear regression. RESULTS: We collected data from 660 FPDs (response rate 82%). For all EPAs, FPDs did not require fellows to reach the level of entrustment for graduation that they expected of subspecialists to practice (P < .001). FPDs expected the least amount of supervision for the EPAs consultation and handovers. Mean differences between supervision levels for graduation and practice were smaller for clinical EPAs (consultation, handovers, lead a team) when compared with nonclinical EPAs (quality improvement, management, lead the profession and scholarship; P = .001) and were similar across nearly all subspecialties. CONCLUSIONS: Fellowship graduates may need continued development of clinical and nonclinical skills in their early practice period, underscoring a need for continued assessment and mentoring. Graduation readiness must be based on clear requirements, with alignment of FPD expectations and regulatory standards, to ensure quality care for patients.

Stratification of risk of progression to colectomy in ulcerative colitis via measured and predicted gene expression.

An important goal of clinical genomics is to be able to estimate the risk of adverse disease outcomes. Between 5% and 10% of individuals with ulcerative colitis (UC) require colectomy within 5 years of diagnosis, but polygenic risk scores (PRSs) utilizing findings from genome-wide association studies (GWASs) are unable to provide meaningful prediction of this adverse status. By contrast, in Crohn disease, gene expression profiling of GWAS-significant genes does provide some stratification of risk of progression to complicated disease in the form of a transcriptional risk score (TRS). Here, we demonstrate that a measured TRS based on bulk rectal gene expression in the PROTECT inception cohort study has a positive predictive value approaching 50% for colectomy. Single-cell profiling demonstrates that the genes are active in multiple diverse cell types from both the epithelial and immune compartments. Expression quantitative trait locus (QTL) analysis identifies genes with differential effects at baseline and week 52 follow-up, but for the most part, differential expression associated with colectomy risk is independent of local genetic regulation. Nevertheless, a predicted polygenic transcriptional risk score (PPTRS) derived by summation of transcriptome-wide association study (TWAS) effects identifies UC-affected individuals at 5-fold elevated risk of colectomy with data from the UK Biobank population cohort studies, independently replicated in an NIDDK-IBDGC dataset. Prediction of gene expression from relatively small transcriptome datasets can thus be used in conjunction with TWASs for stratification of risk of disease complications.

Creation of a Pediatric Choledocholithiasis Prediction Model.

BACKGROUND: Definitive non-invasive detection of pediatric choledocholithiasis could allow more efficient identification of those patients who are most likely to benefit from therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for stone extraction. OBJECTIVE: To craft a pediatric choledocholithiasis prediction model using a combination of commonly available serum laboratory values and ultrasound results. METHODS: A retrospective review of laboratory and imaging results from 316 pediatric patients who underwent intraoperative cholangiogram or ERCP due to suspicion of choledocholithiasis were collected and compared to presence of common bile duct stones on cholangiography. Multivariate logistic regression with supervised machine learning was used to create a predictive scoring model. Monte-Carlo cross-validation was used to validate the scoring model and a score threshold that would provide at least 90% specificity for choledocholithiasis was determined in an effort to minimize non-therapeutic ERCP. RESULTS: Alanine aminotransferase (ALT), total bilirubin, alkaline phosphatase, and common bile duct diameter via ultrasound were found to be the key clinical variables to determine the likelihood of choledocholithiasis. The dictated specificity threshold of 90.3% yielded a sensitivity of 40.8% and overall accuracy of 71.5% in detecting choledocholithiasis. Positive predictive value was 71.4% and negative predictive value was 72.1%. CONCLUSION: Our novel pediatric choledocholithiasis predictive model is a highly specific tool to suggest ERCP in the setting of likely choledocholithiasis.

Continued Supervision for the Common Pediatric Subspecialty Entrustable Professional Activities May Be Needed Following Fellowship Graduation.

PURPOSE: Entrustable professional activities (EPAs) are one approach to competency-based medical education (CBME), and 7 EPAs have been developed that address content relevant for all pediatric subspecialties. However, it is not known what level of supervision fellowship program directors (FPDs) deem necessary for graduation. The Subspecialty Pediatrics Investigator Network (SPIN) investigated FPD perceptions of the minimum level of supervision required for a trainee to successfully graduate. METHOD: In 2017, SPIN surveyed all FPDs of accredited fellowships for 14 subspecialties. For each EPA, the minimum supervision level for graduation (ranging from observation only to unsupervised practice) was set such that no more than 20% of FPDs would accept a lower level. RESULTS: The survey response rate was 82% (660/802). The minimum supervision level for graduation varied across the 7 EPAs from 2 (direct) to 4 (indirect for complex cases), with significant differences between EPAs. The percentage of FPDs desiring a lower minimum supervision level ranged from 3% to 17%. Compared with the 4 nonclinical EPAs (quality improvement, management, lead within the profession, scholarship), the 3 clinical EPAs (consultation, handover, lead a team) had higher minimum supervision graduation levels (P < .001), with less likelihood that an FPD would graduate a learner below their minimum level (P < .001). CONCLUSIONS: Consensus among FPDs across all pediatric subspecialties demonstrates the potential need for ongoing supervision for graduates in all 7 common pediatric subspecialty EPAs after fellowship. As CBME programs are implemented, processes and infrastructure to support new graduates are important considerations for leaders.

Site- and Taxa-Specific Disease-Associated Oral Microbial Structures Distinguish Inflammatory Bowel Diseases.

BACKGROUND: The gut and oral microbiome have independently been shown to be associated with inflammatory bowel disease (IBD). However, it is not known to what extent gut and oral microbial disease markers converge in terms of their composition in IBD. Further, the spatial and temporal variation within the oral microenvironments of IBD remain to be elucidated. PATIENTS AND METHODS: We used a prospectively recruited cohort of patients with IBD (n = 47) and unrelated healthy control patients (n = 18) to examine the spatial and temporal distribution of microbiota within the various oral microenvironments, represented by saliva, tongue, buccal mucosa, and plaque, and compared them with stool. Microbiome characterization was performed using 16S rRNA gene sequencing. RESULTS: The oral microbiome displayed IBD-associated dysbiosis, in a site- and taxa-specific manner. Plaque samples depicted a relatively severe degree of dysbiosis, and the disease-associated dysbiotic bacterial groups were predominantly the members of the phylum Firmicutes. Our 16S rRNA gene analyses show that oral microbiota can distinguish patients with IBD from healthy control patients, with salivary microbiota performing the best, closely matched by stool and other oral sites. Longitudinal profiles of microbial composition suggest that some taxa are more consistently perturbed than others, preferentially in a site-dependent fashion. CONCLUSIONS: Collectively, these data indicate the potential of using oral microbial profiles in screening and monitoring patients with IBD. Furthermore, these results support the importance of spatial and longitudinal microbiome sampling to interpret disease-associated dysbiotic states and eventually to gain insights into disease pathogenesis.
