Improvement Science Increases Routine Lipid Screening in General Pediatric Cardiology.

OBJECTIVE: To evaluate the effectiveness of patient education, physician counseling, and point-of-care (POC) testing on improving adherence to lipid screening national guidelines in a general pediatric cardiology practice (2017-2023). STUDY DESIGN: Regional primary care providers were surveyed regarding lipid screening practices. Key drivers were categorized (physician, patient, and system) with corresponding interventions. Pediatric cardiologists started offering lipid screening during regular visits by providing families with preventive cardiovascular education materials and lab phlebotomy testing. System redesign included educational posters, clinical intake protocol, physician counseling, electronic health record integration, and POC testing. Run charts and statistical process control charts measured screening rates and key processes. RESULTS: The primary care survey response rate was 32% (95/294); 97% supported pediatric cardiologists conducting routine lipid screening. Pediatric cardiology mean baseline lipid screening rate was 0%, increased to 7% with patient education, and to 61% after system redesign including POC testing. Screening rates among 1467 patients were similar across age groups (P = .98). More patients received lipid screening by POC (91.7%) compared with phlebotomy (8.3%). Lipid abnormalities detected did not differ by screening methodology (P = .49). CONCLUSION: Patient education, counseling, and POC testing improved adherence to national lipid screening guidelines, providing a possible model for primary care implementation.

Obstetric imaging practice characteristics associated with prenatal detection of critical congenital heart disease in a rural US region over 20 years.

OBJECTIVE: To identify clinical practice characteristics associated with the frequency of prenatal critical congenital heart disease (CCHD) detection (i.e., the number of liveborn infants with postnatally confirmed CCHD identified on prenatal sonography) over 20 years in a rural setting comprised of 11 primarily low-volume obstetric hospitals and the single tertiary academic hospital to which they refer. METHODS: This was a retrospective cohort study of all patients in the referral region with an initial prenatal and/or postnatal diagnosis of CCHD from 01/01/2002 to 12/31/2021. The frequency of prenatal CCHD detection at the time of an obstetric ultrasound was reported, as was the change in detection over time. Critical congenital heart disease detection was assessed as a function of cardiac lesion type, practice setting, and practice characteristics. RESULTS: There were 271 cases with a confirmed postnatal CCHD diagnosis, of which 49% were identified prenatally. The majority of community practices each averaged <10 CCHD cases in total over the study period. Prenatal detection at the tertiary academic hospital's obstetric ultrasound unit was 64%, compared to 22% at the combined referring community practices (p < 0.001), though CCHD detection improved over time in both settings. Professional accreditation by the American Institute of Ultrasound in Medicine, image interpretation by radiology or Maternal Fetal Medicine, and use of video clips of ventricular outflow tracts were associated with improved prenatal CCHD detection. CONCLUSIONS: Our data demonstrate the infrequency of CCHD cases at small-volume, rural hospitals and the substantial variation in prenatal CCHD detection across practice settings. Our methods allowed for the identification of practice characteristics associated with prenatal CCHD detection.

Bicuspid aortic valve and its ascending aortopathy.

PURPOSE OF REVIEW: To synthesize and critically assess recent clinical and research advancements in pediatric bicuspid aortic valve (BAV) and its associated aortopathy. RECENT FINDINGS: In pediatric patients with BAV, progressive aortic dilation (i.e. bicuspid aortopathy) is commonly present and associated with increased risk for aortic aneurysm, dissection, and surgery in adulthood. Ongoing research explores the cause, incidence, and progression of bicuspid aortopathy to promote earlier diagnosis and improve preventive management. Recent findings include: high familial incidence and need for improved familial screening; safety of recreational physical activity in most affected children; potential for medical management to slow aortic growth; feasibility of pediatric registries to evaluate longitudinal outcomes; and potential genetic and hemodynamic biomarkers for disease risk stratification. SUMMARY: Pediatric bicuspid aortopathy is an important area for investigation and preventive management to improve long-term cardiovascular outcomes. Recent literature promotes familial screening, recreational exercise, medical prophylaxis, registry-based longitudinal evaluation, and continued scientific inquiry.

Living with Congenital Aortic Stenosis: Exercise Restriction, Patterns of Adherence, and Quality of Life.

Modern consensus panel guidelines recommend restriction from most organized sports for patients with moderate or severe aortic stenosis (AS). However, there is little published data on how frequently physicians deviate from guidelines, how well patients adhere to exercise restrictions, or the effect of restriction on patient-reported quality of life. In this study, we surveyed 93 subjects with AS and their cardiologists regarding participation in organized sports, physical activity, weightlifting, and exercise restriction. Subjects completed the pediatric quality of life inventory (PedsQL) and the pediatric cardiac quality of life inventory (PCQLI). We found that subjects with severe AS (n = 3) were commonly, but not universally, restricted from organized sports (n = 2, 66%). Subjects with moderate AS (n = 40) were rarely restricted from organized sports (n = 6, 17%). No physician-specific characteristics were associated with increased likelihood of recommending exercise restriction. Subjects were more likely to be restricted if they were older (16 years vs. 13 years, p 0.02) and had moderate versus mild AS (p 0.013). PCQLI scores for teens and young adults with AS (age 13-25) were lower than a comparison group of patients with mild congenital heart disease. For all age groups, the PedsQL social functioning score was lower for subjects with exercise restriction (p 0.052). In summary, cardiologists apply consensus guidelines leniently when restricting patients with moderate/severe AS from organized sports and weightlifting. Patients with AS routinely adhere to exercise restriction recommendations. Children and young adults with AS and exercise restriction have lower QOL scores in the social functioning domain.

Indomethacin for symptomatic patent ductus arteriosus in preterm infants.

BACKGROUND: Symptomatic patent ductus arteriosus (PDA) is associated with mortality and morbidity in preterm infants. In these infants, prophylactic use of indomethacin, a non-selective cyclooxygenase inhibitor, has demonstrated short-term clinical benefits. The effect of indomethacin in preterm infants with a symptomatic PDA remains unexplored. OBJECTIVES: To determine the effectiveness and safety of indomethacin (given by any route) compared to placebo or no treatment in reducing mortality and morbidity in preterm infants with a symptomatic PDA. SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to search Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 7), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R); and Cumulative Index to Nursing and Allied Health Literature (CINAHL), on 31 July 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomized controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA: We included RCTs and quasi-RCTs that compared indomethacin (any dose, any route) versus placebo or no treatment in preterm infants. DATA COLLECTION AND ANALYSIS: We used the standard methods of Cochrane Neonatal, with separate evaluation of trial quality and data extraction by at least two review authors. We used the GRADE approach to assess the certainty of evidence for the following outcomes: failure of PDA closure within one week of administration of the first dose of indomethacin; bronchopulmonary dysplasia (BPD) at 28 days' postnatal age and at 36 weeks' postmenstrual age; proportion of infants requiring surgical ligation or transcatheter occlusion; all-cause neonatal mortality; necrotizing enterocolitis (NEC) (≥ Bell stage 2); and mucocutaneous or gastrointestinal bleeding. MAIN RESULTS: We included 14 RCTs (880 preterm infants). Four out of the 14 included studies were judged to have high risk of bias in one or more domains. Indomethacin administration was associated with a large reduction in failure of PDA closure within one week of administration of the first dose (risk ratio (RR) 0.30, 95% confidence interval (CI) 0.23 to 0.38; risk difference (RD) -0.52, 95% CI -0.58 to -0.45; 10 studies, 654 infants; high-certainty evidence). There may be little to no difference in the incidence of BPD (BPD defined as supplemental oxygen need at 28 days' postnatal age: RR 1.45, 95% CI 0.60 to 3.51; 1 study, 55 infants; low-certainty evidence; BPD defined as supplemental oxygen need at 36 weeks' postmenstrual age: RR 0.80, 95% CI 0.41 to 1.55; 1 study, 92 infants; low-certainty evidence) and probably little to no difference in mortality (RR 0.78, 95% CI 0.46 to 1.33; 8 studies, 314 infants; moderate-certainty evidence) with use of indomethacin for symptomatic PDA. No differences were demonstrated in the need for surgical PDA ligation (RR 0.66, 95% CI 0.33 to 1.29; 7 studies, 275 infants; moderate-certainty evidence), in NEC (RR 1.27, 95% CI 0.36 to 4.55; 2 studies, 147 infants; low-certainty evidence), or in mucocutaneous or gastrointestinal bleeding (RR 0.33, 95% CI 0.01 to 7.58; 2 studies, 119 infants; low-certainty evidence) with use of indomethacin compared to placebo or no treatment. Certainty of evidence for BPD, surgical PDA ligation, NEC, and mucocutaneous or gastrointestinal bleeding was downgraded for very serious or serious imprecision. AUTHORS' CONCLUSIONS: High-certainty evidence shows that indomethacin is effective in closing a symptomatic PDA compared to placebo or no treatment in preterm infants. Evidence is insufficient regarding effects of indomethacin on other clinically relevant outcomes and medication-related adverse effects.

Outcomes for Ectopia Cordis.

OBJECTIVES: To utilize a large multicenter neonatal cohort to describe survival and clinical outcomes of very low birth weight (VLBW) or preterm infants with ectopia cordis. STUDY DESIGN: Data were prospectively collected on 2 211 262 infants (born 2000-2017) from 845 US centers. Both VLBW (401-1500 g or 22-29 weeks of gestation) and non-VLBW (>1500 g and >29 weeks) infants had diagnoses or anatomic descriptors consistent with ectopia cordis and/or pentalogy of Cantrell. The primary outcome was neonatal survival, defined as hospital discharge or initial length of stay of ≥12 months. RESULTS: In total, 180 infants had ectopia cordis, 135 (76%) with findings of pentalogy of Cantrell. VLBW infants comprised 52% of the population. VLBW mortality was 96% with 79% dying within 12 hours, compared with 59% and 36%, respectively, for non-VLBW. One-third of VLBW infants received life support compared with 65% of non-VLBW. Surgery was reported for 34% of VLBW and 68% of non-VLBW infants. Congenital heart disease was reported in 8% of VLBW and 36% of non-VLBW, with conotruncal abnormalities most common. Survival exceeded 50% for infants >2500 g and >37 weeks of gestation. CONCLUSIONS: Survival of VLBW infants with ectopia cordis was poor and substantially worse compared with non-VLBW, with notable discrepancies in resuscitative efforts and surgical interventions. Although gestational age and weight strongly influence current survival, more detailed information regarding the severity of cardiac and noncardiac abnormalities is required to fully determine prognosis and inform counseling.

Impact of dipyridamole on adenosine dosing in pediatric and young adult patients after heart transplantation.

BACKGROUND: Relative contraindications to adenosine use have included heart transplant and dipyridamole. We previously demonstrated the safety and efficacy of adenosine-induced atrioventricular (AV) block in healthy young heart transplant recipients while suspending dipyridamole therapy (dual antiplatelet agent). This prospective follow-up study evaluated the safety and efficacy of adenosine use in the same cohort of heart transplant recipients while on dipyridamole. METHODS: Adenosine was incrementally dosed until AV block occurred (maximum 200 mcg/kg up to 12 mg). The primary outcome was clinically significant asystole (≥12 seconds). Secondary outcomes included maximal adenosine dose, AV block duration, dysrhythmias, and clinical symptoms. Outcomes were compared to the parent study. RESULTS: Thirty of 39 eligible patients (5-24 years) were tested. No patient (0%, CI 0%-8%) experienced clinically significant asystole. AV block occurred in 29/30 patients (97%, CI 86%-100%). The median dose causing AV block was 50mcg/kg (vs 100 mcg/kg off dipyridamole; P = .011). Seventeen patients (57%, CI 39%-72%) required less adenosine to achieve AV block on dipyridamole; six (20%) required more. AV block occurred at doses ≥25 mcg/kg in all patients. In pairwise comparison to prior testing off dipyridamole, no significant change occurred in AV block duration, frequency of cardiac ectopy, or incidence of reported symptoms. No atrial fibrillation/flutter occurred. CONCLUSIONS: AV block often occurs at twofold lower adenosine doses in healthy young heart transplant recipients taking oral dipyridamole, compared with previous testing of this cohort off dipyridamole. Results suggest that initial dosing of 25 mcg/kg (maximum 0.8 mg) with stepwise escalation poses low risk of prolonged asystole on dipyridamole.

Prospective Study of Adenosine on Atrioventricular Nodal Conduction in Pediatric and Young Adult Patients After Heart Transplantation.

BACKGROUND: Supraventricular tachycardia is common after heart transplantation. Adenosine, the standard therapy for treating supraventricular tachycardia in children and adults without transplantation, is relatively contraindicated after transplantation because of a presumed risk of prolonged atrioventricular block in denervated hearts. This study tested whether adenosine caused prolonged asystole after transplantation and if it was effective in blocking atrioventricular nodal conduction in these patients. METHODS: This was a single-center prospective clinical study including healthy heart transplant recipients 6 months to 25 years of age presenting for routine cardiac catheterization during 2015 to 2016. After catheterization, a transvenous pacing catheter was placed and adenosine was given following a dose-escalation protocol until atrioventricular block was achieved. The incidence of clinically significant asystole (≥12 seconds after adenosine) was quantified. The effects of patient characteristics on adenosine dose required to produce atrioventricular block and duration of effect were also measured. RESULTS: Eighty patients completed adenosine testing. No patient (0%; 95% confidence interval, 0-3) required rescue ventricular pacing. Atrioventricular block was observed in 77 patients (96%; 95% confidence interval, 89-99). The median longest atrioventricular block was 1.9 seconds (interquartile range, 1.4-3.2 seconds), with a mean duration of adenosine effect of 4.3±2.0 seconds. No patient characteristic significantly predicted the adenosine dose to produce atrioventricular block or duration of effect. Results were similar across patient weight categories. CONCLUSIONS: Adenosine induces atrioventricular block in healthy pediatric and young adult heart transplant recipients with minimal risk when low initial doses are used (25 µg/kg; 1.5 mg if ≥60 kg) and therapy is gradually escalated.

Transcatheter stenting of superior vena cava obstruction after pediatric heart transplantation: A single-center experience assessing risk factors and outcomes.

Transcatheter stent implantation for SVC obstruction following OHT has been well described, particularly in pediatric patients. This study describes a large single-center pediatric heart transplant experience that investigates the risk factors for SVC stenosis requiring stent implantation and its associated outcomes. All pediatric OHTs between January 1, 2000, and December 12, 2016, were examined for risk factors. Twelve of 349 (3.4%) OHTs required SVC stent implantation. Patients who required stents were younger (2.5 years vs 10.0 years, P = 0.0097), weighed less (8.6 kg vs 26.0 kg, P = 0.0024), and were more likely to have had CHD (83% vs 32%, P = 0.001) or previous SCPA (58% vs 18%, P = 0.002). Bicaval anastomosis was not associated with subsequent SVC stent implantation. Symptoms included SVC syndrome and chylous effusions. All 12 patients had evidence of significant SVC obstruction by both echocardiographic Doppler interrogation and transcatheter angiography. There were no acute procedural complications; however, reinterventions were common (four of 12 patients) and occurred at a mean of 5.7 ± 3.6 months poststent implantation. In conclusion, transcatheter SVC stent implantation is safe and effective after OHT. There were significant associations between SVC stent implantation and younger age, smaller weight, CHD, and history of SCPA, but not with bicaval anastomosis or donor-recipient weight ratio.

Pediatric Cardiology Condolence Letter Writing: Does a Fellowship Curriculum Impact Practice?

CONTEXT: Condolence letter (CL) writing after the death of a child is an important opportunity for humanism. Pediatric cardiology fellowship training now recognizes the importance of palliative care, but rarely includes CL education, despite its fragile patient population. OBJECTIVES: To address this professionalism gap, a formal CL writing curriculum was created and implemented in a pediatric cardiology fellowship. This study investigated the impact of the curriculum on pediatric cardiology CL writing, and broader CL practices and beliefs. METHODS: Pediatric cardiology fellows at a high volume urban academic program from 2000 to 2022 were divided into two cohorts (exposure to CL curriculum [2014-2022] vs. no exposure [2000-2013]) and responded by anonymous electronic multiple choice and open ended survey to assess the CL curriculum and describe current CL practices and beliefs. Impact of curriculum elements was determined by ordinal ranking. A 5-point Likert scale was used to report physician behaviors. Chi-square tests of independence were utilized for group comparisons. RESULTS: The overall survey response rate was 59% (63/107). Cardiologists who participated in the curriculum (64%, 35/55) were more likely to report writing CLs (80% vs. 40%; P < 0.01). Impactful curriculum elements included the opportunity for all fellows to contribute to a CL (78%) and identifying a primary fellow to write the CL (66%). A majority (>75%) of curriculum participants agreed that formal teaching increased their frequency, ability, and comfort in writing CLs. CONCLUSION: Development of condolence expression educational programs in pediatric cardiology training should be expanded.

Retrospective study of medical student scholarship and career trajectory following a mentored preclinical cardiovascular summer research fellowship.

OBJECTIVES: Developing a preclinical training infrastructure for cardiovascular clinician-scientists is an academic workforce priority. The Cardiovascular Research Institute of Vermont developed a cardiovascular summer research fellowship (SRF), wherein medical student awardees were selected by merit-based application and completed mentored research between the first and second years. We aimed to study the impact of the SRF on medical student scholarship and career planning. DESIGN: Retrospective survey study. SETTING: Single academic medical centre. PARTICIPANTS: All SRF participants from 2015 to 2020. INTERVENTIONS: Not applicable. PRIMARY AND SECONDARY OUTCOME MEASURES: Prior SRF participants were surveyed to ascertain current position, research engagement and perspectives regarding SRF experience. Comparisons to American Association of Medical Colleges Graduation Questionnaire data from equivalent years were made using χ2 tests. RESULTS: Survey response rate was 87% (20/23), 55% were women. Median time from SRF completion was 2 years (IQR 0.75-2.25), with 75% still enrolled in medical school and 25% in residency. As a result of the first-year summer programme, 45% published a peer-reviewed abstract or manuscript, which was equivalent to the national rate for graduating students (53%, p=0.4). Most respondents (80%) were active in additional research projects during school separate from the SRF, 90% anticipated a career involving research (vs 53% nationally, p<0.001) and 75% planned to pursue a career in cardiovascular medicine. CONCLUSION: Medical students completing a mentored cardiovascular SRF after their first year have a high rate of academic scholarship, with publication rate already equivalent to national peer graduates. Preclinical SRF students strongly anticipate cardiovascular medicine and research careers.

Increasing Pediatric Morning Report Educational Value Through Quality Improvement.

BACKGROUND: Morning report (MR) is a common case-based conference in graduate medical education. Recent studies highlight participant dissatisfaction with the educational value of MR, but data are lacking on means for improvement. We aimed to increase MR quality and participant satisfaction at our academic pediatric residency program. METHODS: Improvement science was used to develop and implement a new standardized pediatric MR process (intervention), with 5 core educational elements and structured resident-faculty mentorship. Educational elements were measured via feedback forms and tracked using a run chart. Residents and faculty were surveyed regarding MR quality and satisfaction at baseline and 6 months postintervention; responses were analyzed using mixed effects logistic regression. RESULTS: The median of educational elements increased from 3 to 5 (5 maximum) during the 6-month study period and 12-months poststudy. Baseline and postintervention survey response rates were 90% (18 of 20) for residents and 66% (51 of 77) for faculty. Residents reporting high quality MR changed from 50% to 72% (P = .20), and faculty from 29% to 85% (P <.001). Satisfaction with MR content increased for both residents (50%-89%, P = .03) and faculty (25%-67%, P <.001). Resident satisfaction with faculty mentorship before MR increased from 28% to 78% (P = .01); satisfaction with faculty feedback after MR increased from 11% to 56% (P = .02). CONCLUSIONS: Improvement science can be used to develop a new pediatric graduate medical education process. Requiring core educational elements and providing structured mentorship were associated with improvements in pediatric MR quality and participant satisfaction.

Simulation as an Educational Tool in the Pediatric Cardiac Intensive Care Unit.

PURPOSE OF REVIEW: This review highlights the use of simulation as an educational tool in the highly specialized pediatric cardiac intensive care unit (PCICU). RECENT FINDINGS: Healthcare simulation is used in high acuity medical environments to test healthcare systems. Healthcare simulation can improve team training, patient safety, and improve medical decision-making. Complex physiologies in the PCICU demand effective teamwork to consistently deliver high-quality patient care. Simulation-based PCICU learning objectives depend on a structured cognitive load framework to account for individual learner abilities, team constructs, and healthcare resources. SUMMARY: PCICU simulation programs are strengthened by utilizing traditional education theory, with careful consideration of complex physiologies, interprofessional personnel, and center-specific resources. Virtual platforms should continue to evolve to provide additional, more convenient venues for individual learners and teams. Healthcare systems should frequently intersect with simulation educators to create relevant learning objectives that will contribute to patient safety, improve team performance, and patient outcomes.

Effect of Losartan or Atenolol on Children and Young Adults With Bicuspid Aortic Valve and Dilated Aorta.

Bicuspid aortic valve aortopathy is defined by dilation of the aortic root (AoRt) and/or ascending aorta (AsAo), and increases risk for aortic aneurysm and dissection. The effects of medical prophylaxis on aortic growth rates in moderate to severe bicuspid aortopathy have not yet been evaluated. This was a single-center retrospective study of young patients (1 day to 29 years) with bicuspid aortopathy (AoRt or AsAo z-score ≥ 4 SD, or absolute dimension ≥ 4 cm), treated with either losartan or atenolol. Maximal diameters and BSA-adjusted z-scores obtained from serial echocardiograms were utilized in a mixed linear effects regression model. The primary outcome was the annual rate of change in AoRt and AsAo z-scores during treatment, compared with before treatment. The mean ages (years) at treatment initiation were 14.2 ± 5.1 (losartan; n = 27) and 15.2 ± 4.9 (atenolol; n = 18). Median treatment duration (years) was 3.1 (IQR 2.4, 6.0) for losartan, and 3.7 (IQR 1.4, 6.6) for atenolol. Treatment was associated with decreases in AoRt and AsAo z-scores (SD/year), for both losartan and atenolol (pre- vs post-treatment): losartan/AoRt: +0.06 ± 0.02 vs -0.14 ± 0.03, p < 0.001; losartan/AsAo: +0.20 ± 0.03 vs -0.09 ± 0.05, p < 0.001; atenolol/AoRt: +0.07 ± 0.03 vs -0.02 ± 0.04, p = 0.04; atenolol/AsAo: +0.21 ± 0.04 vs -0.06 ± 0.06, p < 0.001. Treatment was also associated with decreases in absolute growth rates (cm/year) for all comparisons (p ≤ 0.02). Medical prophylaxis reduced proximal aortic growth rates in young patients with at least moderate and progressive bicuspid aortopathy.

Impact of an institutional grant award on early career investigator applicants and peer reviewers.

BACKGROUND: Obtaining research funding support is integral to a successful career in science. Training and practice in grant writing, as well as engagement in peer review of grant applications may help lead to successful research funding. However, there is little evidence on the impact of institutional programs on the career development of early career investigators (ECIs). OBJECTIVES: Understand the impact of participation in an institutional research award program on the career development of ECIs. METHODS: The Cardiovascular Research Institute of Vermont established an Early Career Research (ECR) award program in 2018. ECIs who participated as applicants or reviewers in the first 3 years of the program (2018-2020) were surveyed to understand the impact of the ECR award program on their grant writing and professional development. RESULTS: Ninety-four percent of 17 applicants and 90% of 19 reviewers completed the survey. Ninety-two percent of funded and 75% of unfunded applicants, and 87% of reviewers reported that the program was beneficial to their professional development. Similarly, 85% of funded applicants, 75% of unfunded applicants, and 80% of reviewers reported improvement in their grant-writing skills. All respondents reported they would recommend the ECR award program to their peers. CONCLUSIONS: This single-institution ECR award program had a positive impact on ECI's professional development and grant-writing skills and may lead to further extramural funding opportunities.

Variation of Patent Ductus Arteriosus Treatment in Very Low Birth Weight Infants.

BACKGROUND: Patent ductus arteriosus (PDA) treatment is common among very low birth weight (VLBW) infants. Given limitations in evidence, controversy exists regarding treatment risks and benefits. In this study, we describe PDA treatment trends and variation in a large, US, multicenter VLBW infant cohort. METHODS: Data were collected through Vermont Oxford Network on 291 292 VLBW infants born 2012-2019 at 806 US NICUs. PDA diagnosis and treatment rates, further categorized as pharmacologic, invasive, or combined, were determined. NICUs were classified as capable versus noncapable of invasive PDA treatment. Infant and hospital characteristics were examined by NICU type and treatment quartile. Geographic NICU distribution and treatment rates were described in 9 US census divisions. RESULTS: Of all infants, 24.6% were diagnosed with and 20.5% were treated for PDA. Diagnosis and treatment rates decreased over the study period. Treatment was predominantly pharmacologic. Treatment rates varied widely among NICUs (0% to 67%) despite similar infant characteristics. The median treatment rate was higher at NICUs capable of pharmacologic and invasive treatment (20.3%, interquartile range 13.3-28.6) than at NICUs capable of only pharmacologic treatment (8.9%, interquartile range 2.9-14.8). Treatment rates were highest in the northeast and lowest in the west. Invasive treatment was more common in the west. CONCLUSIONS: PDA diagnosis and treatment rates are trending downward. Wide variation exists in PDA treatment despite a largely uniform VLBW infant population. This variation correlates with differences in hospital treatment capabilities and geography. Further understanding of the effects of treatment disparity could aid in guiding clinical management.

Successful Increase of Outpatient Clinic Continuity in a Fellowship Quality Improvement Project.

BACKGROUND: Patient-to-physician continuity is the result of coordinated and consistent care. Optimizing continuity can be a challenge in medical training without impacting work hours. We sought to use quality improvement science during graduate medical training to increase outpatient continuity. OBJECTIVE: The primary goal was to improve outpatient continuity in our pediatric cardiology fellowship, without increasing trainee clinic hours, from a baseline of 38% to ≥70% within 18 months. METHODS: Our fellowship conducted a quality improvement project across 3 years to improve continuity-of-care in our outpatient clinic using the Institute for Healthcare Improvement model for improvement. We conducted Plan-Do-Study-Act cycles and completed a key driver diagram using a multidisciplinary team. We defined continuity as a patient being evaluated by their primary fellow or a different fellow that was provided a handoff. The outcome measure was the continuity rate over 2-week periods. RESULTS: Continuity improved from 38% to ≥80%. The improvement resulted from a series of interventions, including creating a handoff system among fellows, identifying follow-up patients in advance, and communicating this information to the clinic team. Although we anticipated a decrease when new fellows were incorporated, continuity continued to be ≥70%. This system retained continuity above 90% one year after completion of the project. CONCLUSIONS: Our fellowship created a system change to improve primary patient-to-fellow continuity care rates. We achieved sustainable continuity by working with a multidisciplinary team without altering staffing, infrastructure, or fellow work hours. This project engaged trainees to address the practical application of quality improvement methodology to solve a common clinical problem.

A Case of Mitral Valve Endocarditis Complicated by Multiple Embolic Phenomena: Leaping from Adult Guidelines to Pediatric Critical Care Decisions.

Early surgical intervention for children with infective endocarditis (IE) and cerebrovascular sequelae has significant risks, resulting in practice variation amongst pediatric cardiologists, intensivists, and cardiothoracic surgeons. The limited pediatric consensus recommendations make decision making for practitioners challenging. The added risk of multiorgan dysfunction syndrome can make these decisions even more difficult. We present the case of a 14-year-old with IE and resultant multiorgan dysfunction syndrome including cerebrovascular complication, successfully treated by primary valve repair within the 1st week of diagnosis.
