Engaging All Stakeholders to Create a Trusted, Data-Driven, Process Improvement Approach to Addressing Learner Mistreatment.

Problem: Learner mistreatment has remained an ongoing challenge in academic medicine despite accreditation requirements mandating that every program has systems in place to prevent and respond to mistreatment. While efforts vary across institutions, much remains unanswered in the literature about best practices. Additionally, for the foreseeable future, challenges in the learning environment will likely continue and potentially worsen, given the confluence of multiple external stressors including the COVID-19 pandemic, faculty burnout and general political divisiveness in the nation. It is essential, therefore, to focus on indicators of improvement via process metrics such as knowledge and awareness of mistreatment policies and procedures, willingness to report, reasons for not reporting, and satisfaction with having made a report, while simultaneously focusing on the more complex challenge of eliminating mistreatment occurrences. Intervention: We describe the aspects of our mistreatment prevention and response system first implemented in 2017 along with process and outcome measures. The interventions included expanding our policy outlining appropriate conduct in the teacher-learner relationship; a graduated response protocol to allegations of mistreatment with a clear escalation approach; an online reporting system; a graduate medical education exit survey which mirrors the AAMC Graduation Questionnaire on mistreatment; a robust communication and professional development campaign; a comprehensive data dashboard; and a comprehensive summary report dissemination plan. Context: The interventions were implemented at the largest allopathic medical school in the U.S., with nine campuses across the state. The system is available to all learners, including medical students, graduate students, residents, and fellows. Impact: Both institutional and national data sources have informed the continuous improvement strategies. Data from internal reporting systems, institutional surveys, and national data are presented from 2017 to 2021. Findings include an increasing number of incidents reported each year, including confidential reports from students who include their contact information rather than report anonymously, which we view as an indicator of learner trust in the system. Our data also show consistent improvements in learners' awareness of the policy and procedures and satisfaction with having made a report. We also include other data such as the nature of complaints submitted and timeliness of our institutional response. Lessons Learned: We present several lessons learned that may guide other institutions looking to similarly improve their mistreatment systems, such as a close partnership between faculty affairs, diversity affairs, and educational affairs leadership; communication, professional development, and training through multiple venues and with all stakeholders; easily accessible reporting with anonymous and confidential options and the ability to report on behalf of others; policy development guidance; data transparency and dissemination; and trust-building activities and ongoing feedback from learners.

Defining and identifying early-onset lung disease in cystic fibrosis with cumulative clinical characteristics.

BACKGROUND: Because of the heterogeneity in cystic fibrosis (CF) lung disease among young children, a clinical method to identify early-onset lung disease is needed. OBJECTIVE: To develop a CF early-onset lung disease (CFELD) scoring system by utilizing prospectively collected longitudinal data on manifestations in the first 3 years of life. DESIGN: We studied 145 infants born during 2012-2017, diagnosed through newborn screening by age 3 months, and followed to 36 months of age. Cough severity, pulmonary exacerbations (PEx), respiratory cultures, and hospitalizations were collected at each CF center visit (every 1-2 months in infancy and quarterly thereafter). These data were used to construct the CFELD system and to classify lung disease into five categories: asymptomatic, minimal, mild, moderate, and severe. RESULTS: The most frequent manifestation of CF early lung disease was MD-reported PEx episodes, PEx hospitalizations, and positive Pseudomonas aeruginosa cultures. Parent-reported cough severity was correlated with the number of respiratory hospitalizations (r = 0.48, p < 0.0001). The distribution of CFELD categories was 10% asymptomatic, 17% minimal, 29% mild, 33% moderate, and 12% severe. The moderate and severe categories occurred threefold higher in pancreatic insufficient (PI, 49%) versus sufficient subjects (16%), p < 0.0001. In addition to PI, gastrointestinal and nutrition-related hospitalizations, plasma cytokines interleukin (IL)-6 and IL-10, duration of CFTR modulator therapy, and type of health insurance were significant predictors of CFELD scores. CONCLUSION: The CFELD scoring system is novel, allows systematic evaluation of lung disease prognosis early, and may aid in therapeutic decision-making particularly in the initiation of CFTR modulator therapy.

Efficacy, cost effectiveness, and sustainability of a pediatric high risk asthma clinic.

AIM: At our institution, a pediatric High Risk Asthma clinic has been in operation for over 15 years, targeting children with poorly controlled, and difficult to treat asthma. This study evaluates the outcomes and cost-effectiveness of the High Risk Asthma clinic from 2000 through 2014. METHODS: A retrospective chart review was performed on all patients entering High Risk Asthma clinic from 2000-2014, and total hospitalizations and Emergency Department visits were tallied for the year prior to entering clinic and the year after. Costs incurred, and reimbursements obtained from payors were tallied to determine cost-effectiveness and sustainability. RESULTS: Consistent decreases in hospitalizations (51.2% decrease, P < 0.001) and Emergency Department visits (23.0% decrease, P = 0.048) were seen for patients entering High Risk Asthma clinic, with commensurate significant decreases in related costs. Reimbursements received for outpatient services were sufficient to offset operational costs of the High Risk Asthma clinic, when both clinic visit, and pulmonary function testing charges were included. CONCLUSIONS: A pediatric High Risk Asthma clinic model is efficacious in decreasing hospitalizations and Emergency Department visits for a difficult to treat population, and such a model can be cost-effective and sustainable.

Multifaceted quality improvement initiative to decrease pediatric asthma readmissions.

BACKGROUND: Asthma is the most common chronic disease of childhood and a leading cause of hospitalization in children. A primary goal of asthma control is prevention of hospitalizations. A hospital admission is the single strongest predictor of future hospital admissions for asthma. The 30-day asthma readmission rate at our institution was significantly higher than that of other hospitals in the Children's Hospital Association. As a result, a multifaceted quality improvement project was undertaken with the goal of reducing the 30-day inpatient asthma readmission rate by 50% within two years. METHODS: Analysis of our institution's readmission patterns, value stream mapping of asthma admission, discharge, and follow-up processes, literature review, and examination of comparable successful programs around the United States were all utilized to identify potential targets for intervention. Interventions were implemented in a stepwise manner, and included increasing inhaler availability after discharge, modifying asthma education strategies, and providing in-home post-discharge follow-up. The primary outcome was a running 12-month average 30-day inpatient readmission rate. Secondary outcomes included process measures for individual interventions. RESULTS: From a peak of 7.98% in January 2013, a steady decline to 1.65% was observed by July 2014, which represented a 79.3% reduction in 30-day readmissions. CONCLUSION: A significant decrease in hospital readmissions for pediatric asthma is possible, through comprehensive, multidisciplinary quality improvement that spans the continuum of care.

Diagnosis of Cystic Fibrosis in Screened Populations.

OBJECTIVE: Cystic fibrosis (CF) can be difficult to diagnose, even when newborn screening (NBS) tests yield positive results. This challenge is exacerbated by the multitude of NBS protocols, misunderstandings about screening vs diagnostic tests, and the lack of guidelines for presumptive diagnoses. There is also confusion regarding the designation of age at diagnosis. STUDY DESIGN: To improve diagnosis and achieve standardization in definitions worldwide, the CF Foundation convened a committee of 32 experts with a mission to develop clear and actionable consensus guidelines on diagnosis of CF with an emphasis on screened populations, especially the newborn population. A comprehensive literature review was performed with emphasis on relevant articles published during the past decade. RESULTS: After reviewing the common screening protocols and outcome scenarios, 14 of 27 consensus statements were drafted that apply to screened populations. These were approved by 80% or more of the participants. CONCLUSIONS: It is recommended that all diagnoses be established by demonstrating dysfunction of the CF transmembrane conductance regulator (CFTR) channel, initially with a sweat chloride test and, when needed, potentially with newer methods assessing membrane transport directly, such as intestinal current measurements. Even in babies with 2 CF-causing mutations detected via NBS, diagnosis must be confirmed by demonstrating CFTR dysfunction. The committee also recommends that the latest classifications identified in the Clinical and Functional Translation of CFTR project [http://www.cftr2.org/index.php] should be used to aid with CF diagnosis. Finally, to avoid delays in treatment, we provide guidelines for presumptive diagnoses and recommend how to determine the age of diagnosis.

Diagnosis of Cystic Fibrosis: Consensus Guidelines from the Cystic Fibrosis Foundation.

OBJECTIVE: Cystic fibrosis (CF), caused by mutations in the CF transmembrane conductance regulator (CFTR) gene, continues to present diagnostic challenges. Newborn screening and an evolving understanding of CF genetics have prompted a reconsideration of the diagnosis criteria. STUDY DESIGN: To improve diagnosis and achieve standardized definitions worldwide, the CF Foundation convened a committee of 32 experts in CF diagnosis from 9 countries to develop clear and actionable consensus guidelines on the diagnosis of CF and to clarify diagnostic criteria and terminology for other disorders associated with CFTR mutations. An a priori threshold of ≥80% affirmative votes was required for acceptance of each recommendation statement. RESULTS: After reviewing relevant literature, the committee convened to review evidence and cases. Following the conference, consensus statements were developed by an executive subcommittee. The entire consensus committee voted and approved 27 of 28 statements, 7 of which needed revisions and a second round of voting. CONCLUSIONS: It is recommended that diagnoses associated with CFTR mutations in all individuals, from newborn to adult, be established by evaluation of CFTR function with a sweat chloride test. The latest mutation classifications annotated in the Clinical and Functional Translation of CFTR project (http://www.cftr2.org/index.php) should be used to aid in diagnosis. Newborns with a high immunoreactive trypsinogen level and inconclusive CFTR functional and genetic testing may be designated CFTR-related metabolic syndrome or CF screen positive, inconclusive diagnosis; these terms are now merged and equivalent, and CFTR-related metabolic syndrome/CF screen positive, inconclusive diagnosis may be used. International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes for use in diagnoses associated with CFTR mutations are included.

Cystic Fibrosis Transmembrane Conductance Regulator-Related Metabolic Syndrome and Cystic Fibrosis Screen Positive, Inconclusive Diagnosis.

OBJECTIVE: An unintended consequence of cystic fibrosis (CF) newborn screening (NBS) is the identification of infants with a positive NBS test but inconclusive diagnostic testing. These infants are classified as CF transmembrane conductance regulator-related metabolic syndrome (CRMS) in the US and CF screen positive, inconclusive diagnosis (CFSPID) in other countries. Diagnostic and management decisions of these infants are challenges for CF healthcare professionals and stressful situations for families. As CF NBS has become more widespread across the world, increased information about the epidemiology and outcomes of these infants is becoming available. These data were reviewed at the 2015 CF Foundation Diagnosis Consensus Conference, and a harmonized definition of CRMS and CFSPID was developed. STUDY DESIGN: At the consensus conference, participants reviewed published and unpublished studies of CRMS/CFSPID and used a modified Delphi methodology to develop a harmonized approach to the definition of CRMS/CFSPID. RESULTS: Several studies of CRMS/CFSPID from populations around the world have been published in the past year. Although the studies vary in the number of infants studied, study design, and outcome measures, there have been some consistent findings. CRMS/CFSPID occurs relatively frequently, with CF:CRMS that ranges from 3 to 5 cases of CF for every 1 case of CRMS/CFSPID in regions where gene sequencing is not used. The incidence varies by NBS protocol used, and in some regions more cases of CRMS/CFSPID are detected than cases of CF. The majority of individuals with CRMS/CFSPID do not develop CF disease or progress to a diagnosis of CF. However, between 10% and 20% of asymptomatic infants can develop clinical features concerning for CF, such as a respiratory culture positive for Pseudomonas aeruginosa. Most studies have only reported short-term outcomes in the first 1-3 years of life; the long-term outcomes of CRMS/CFSPID remain unknown. The European CF Society definition of CFSPID and the CF Foundation definition of CRMS differ only slightly, and the consensus conference was able to create a unified definition of CRMS/CFSPID. CONCLUSIONS: CRMS/CFSPID is a relatively common outcome of CF NBS, and clinicians need to be prepared to counsel families whose NBS test falls into this classification. The vast majority of infants with CRMS/CFSPID will remain free from disease manifestations early in life. However, a small proportion may develop clinical features concerning for CF or demonstrate progression to a clinical phenotype compatible with a CF diagnosis, and their long-term outcomes are not known. A consistent international definition of CRMS/CFSPID will allow for better data collection for study of outcomes and result in improved patient care.

Diagnosis of Cystic Fibrosis in Nonscreened Populations.

OBJECTIVE: Although the majority of cases of cystic fibrosis (CF) are now diagnosed through newborn screening, there is still a need to standardize the diagnostic criteria for those diagnosed outside of the neonatal period. This is because newborn screening started relatively recently, it is not performed everywhere, and even for individuals who were screened, there is the possibility of a false negative. To limit irreversible organ pathology, a timely diagnosis of CF and institution of CF therapies can greatly benefit these patients. STUDY DESIGN: Experts on CF diagnosis were convened at the 2015 CF Foundation Diagnosis Consensus Conference. The participants reviewed and discussed published works and instructive cases of CF diagnosis in individuals presenting with signs, symptoms, or a family history of CF. Through a modified Delphi methodology, several consensus statements were agreed upon. These consensus statements were updates of prior CF diagnosis conferences and recommendations. RESULTS: CF diagnosis in individuals outside of newborn screening relies on the clinical evidence and on evidence of CF transmembrane conductance regulator (CFTR) dysfunction. Clinical evidence can include typical organ pathologies seen in CF such as bronchiectasis or pancreatic insufficiency but often represent a broad range of severity including mild cases. CFTR dysfunction can be demonstrated using sweat chloride testing, CFTR molecular genetic analysis, or CFTR physiologic tests. On the basis of the large number of patients with bona fide CF currently followed in registries with sweat chloride levels between 30 and 40 mmol/L, the threshold considered "intermediate" was lowered from 40 mmol/L in the prior diagnostic guidelines to 30 mmol/L. The CF diagnosis was also discussed in the context of CFTR-related disorders in which CFTR dysfunction may be present, but the individual does not meet criteria for CF. CONCLUSIONS: CF diagnosis remains a rare but important condition that can be diagnosed when characteristic clinical features are seen in an individual with demonstrated CFTR dysfunction.

Efficacy and safety of ivacaftor in patients aged 6 to 11 years with cystic fibrosis with a G551D mutation.

RATIONALE: Ivacaftor (VX-770), a cystic fibrosis transmembrane conductance regulator (CFTR) potentiator, has been shown to improve lung function, pulmonary exacerbation rate, respiratory symptoms, and weight gain compared with placebo in patients with cystic fibrosis aged 12 years or older with a G551D-CFTR mutation. OBJECTIVES: This randomized, double-blind, placebo-controlled trial evaluated ivacaftor in patients with cystic fibrosis aged 6-11 years with a G551D-CFTR mutation on at least one allele. METHODS: Patients were randomly assigned to receive ivacaftor administered orally at 150 mg (n = 26) or placebo (n = 26) every 12 hours for 48 weeks in addition to existing prescribed cystic fibrosis therapies. MEASUREMENTS AND MAIN RESULTS: Despite near-normal mean baseline values in FEV1, patients receiving ivacaftor had a significant increase in percent predicted FEV1 from baseline through Week 24 versus placebo group (treatment effect, 12.5 percentage points; P < 0.001). Effects on pulmonary function were evident by 2 weeks, and a significant treatment effect was maintained through Week 48. Patients treated with ivacaftor gained, on average, 2.8 kg more than those receiving placebo at Week 48 (P < 0.001). The change from baseline through Week 48 in the concentration of sweat chloride, a measure of CFTR activity, with ivacaftor was -53.5 mmol/L (P < 0.001) versus placebo. The incidence of adverse events was similar in the two groups. CONCLUSIONS: In patients who are younger and healthier than those in previously studied populations, ivacaftor demonstrated a significant improvement in pulmonary function, weight, and CFTR activity compared with placebo. Clinical trial registered with www.clinicaltrials.gov (NCT00909727).

Hypoalbuminemia in a cystic fibrosis patient with severe erosive esophagitis.

An 8-year-old patient with cystic fibrosis presented with hypoalbuminemia as the main symptom of severe erosive esophagitis. Extensive evaluation failed to reveal a nutrition, pancreatic, intestinal, or renal explanation of his hypoalbuminemia. Identification and treatment of the esophagitis led to resolution of the hypoalbuminemia.

Hepatobiliary abnormalities and disease in cystic fibrosis: epidemiology and outcomes through adulthood.

OBJECTIVES: There is limited data regarding the prevalence of hepatobiliary disease in North American patients with cystic fibrosis (CF) through adulthood. Our aim was to determine the prevalence of, and risk factors for, CF-related hepatobiliary abnormalities and determine factors that predict the development of CF-related hepatobiliary disease. METHODS: We performed a retrospective cohort study of all CF patients who presented to a UnitedStates tertiary care referral academic center over a 32-year period. "CF-related hepatobiliary abnormality" was defined as the presence of abnormal liver chemistries on one or more occasion and "CF-related hepatobiliary disease" was defined as biochemical, physical examination, or ultrasonographic abnormalities on at least 2 consecutive examinations spanning a 1-year period. RESULTS: Two-hundred eighty-three CF patients who presented between the years 1970 and 2002 were identified, with an age range of 2 months to 63 years. Sixty-five percent had CF-related hepatobiliary abnormalities with a higher prevalence seen in CF patients <18 years of age (84% vs. 16%, P<0.01). Fifteen percent of our cohort had CF-related hepatobiliary disease with 93% of cases occurring in individuals before age 18. One quarter of individuals with CF-related hepatobiliary abnormalities developed hepatobiliary disease. CONCLUSIONS: Abnormal liver chemistries in CF are common though most of CF patients lack clinical evidence of liver disease and the severe complications of fibrosis/cirrhosis are rare. The risk of liver involvement decreases significantly with age, falling by 10% per annum for those described as having CF-related hepatobiliary disease. CF-related hepatobiliary disease is a rare occurrence after age 18.

High-attenuation mucus plugs on MDCT in a child with cystic fibrosis: potential cause and differential diagnosis.

High-attenuation mucus plugging is a rare finding in both adults and children. When it occurs, the field of differential diagnoses is typically quite small and includes acute hemorrhage, aspiration of radiodense material, and allergic bronchopulmonary aspergillosis (ABPA). The last of these three diagnoses is the most difficult to make, although ABPA is more commonly seen in children with cystic fibrosis (CF) or asthma. ABPA is radiographically characterized by recurrent mucus plugging, atelectasis, and central bronchiectasis. Thus far, high-attenuation mucus plugs have only been reported in adults. We report a rare case of a child with CF who had high-attenuation mucus plugs and atelectasis that raised the possibility of ABPA. We discuss the differential diagnoses of this finding and the role of multidetector CT in these children.

Growth hormone treatment improves growth and clinical status in prepubertal children with cystic fibrosis: results of a multicenter randomized controlled trial.

CONTEXT: This multicenter, randomized, controlled, crossover trial of prepubertal children with cystic fibrosis (CF) tests the hypotheses that recombinant human GH (rhGH) treatment 1) improves height, weight, lean mass, and bone content irrespective of baseline measures; 2) improves clinical status and quality of life; and 3) has continued effect after cessation after 1 yr of treatment. METHODS: Sixty-one prepubertal subjects (

High-resolution computed tomography imaging of airway disease in infants with cystic fibrosis.

RATIONALE: The development of early lung disease in patients with cystic fibrosis (CF) remains poorly defined. OBJECTIVE: Determine whether asymptomatic infants with CF have evidence for changes in airway structure when assessed by high-resolution computed tomography, and whether airway structure correlates with airway function in this age group. METHODS: Thirteen infants with CF (8-33 mo) and 13 control infants (7-25 mo) were evaluated. Airway wall and lumen areas were measured from three 1-mm-thick cross-sectional images obtained from upper, middle, and lower lobes during a respiratory pause with the lungs inflated to an airway pressure of 20 cm H2O. Lung tissue density was measured from images obtained during a respiratory pause at FRC. Forced expiratory flows were measured by the rapid thoracic compression technique in 11 infants with CF. RESULTS: Airway wall area increased more per unit increase in airway size, whereas airway lumen area increased less per unit increase in airway size in the CF than in the control group. Among infants with CF, a greater ratio of wall to lumen area correlated with lower airway function. In addition, lung density at relaxed (passive) FRC was lower for infants with CF than for control infants (0.38 vs. 0.43 g/ml; p < 0.02). CONCLUSIONS: Our results indicate that infants with CF have thickened airway walls, narrowed airway lumens, and air trapping, when assessed by high-resolution computed tomography, and measurements of airway structure correlated with airway function.

Growth hormone treatment enhances nutrition and growth in children with cystic fibrosis receiving enteral nutrition.

OBJECTIVES: Impaired longitudinal growth and poor weight gain are common and important problems in children with cystic fibrosis. This study evaluates the hypothesis that adjunctive growth hormone (GH) therapy augments the growth response to nutritional supplementation. STUDY DESIGN: We recruited 18 prepubertal children who received enteral nutritional supplementation for at least 2 years before enrollment. Nine were randomly assigned to receive no GH for 1 year, followed by 1 year of GH. Nine were randomly assigned to receive 1 year of GH followed by a second year of GH. Measurements included height, weight, pulmonary function, lean tissue mass, bone mineral content, hospitalizations, outpatient antibiotic use, and caloric intake. RESULTS: Growth hormone resulted in significant improvement in height, weight, bone mineral content, lean tissue mass, and number of hospitalizations. Pulmonary function was similar at baseline. Absolute forced vital capacity and forced expiratory volume in 1 minute significantly increased in GH treatment, but there was no significant change in percent predicted pulmonary function. Caloric intake was similar in both groups during both years. CONCLUSIONS: These results suggest that GH is a useful for enhancing growth in children with cystic fibrosis receiving enteral nutritional supplementation.
