Positive Outcomes of Optimizing Student-Preceptor Continuity in a Traditional Block Clerkship.

PROBLEM: Student-preceptor discontinuity during 3rd-year clerkships limits the quality and quantity of supervision, teaching, and feedback. Although longitudinal integrative clerkships increase continuity and are associated with improved student and preceptor experience, they require schoolwide curricular reform. Alternative innovations enhancing student-preceptor relationships within the constraints of a traditional block clerkship may demonstrate similar benefits. INTERVENTION: We piloted a continuity-enhanced general pediatric ambulatory schedule during 2 consecutive clerkship blocks in 2013. Students in the continuity-enhanced model (n = 29) were assigned 1-3 primary clinic preceptors, whereas those in the traditional model (n = 30) worked with 5-8. Data were gathered from student assessments and anonymous student and preceptor surveys. We used t and Fisher's exact tests to compare the two groups and performed thematic analysis of free-text survey comments. CONTEXT: Our school utilizes a block clerkship model with approximately 30 students rotating through the pediatric clerkship every 8 weeks. During the 3-week ambulatory portion, students spend 8 half days in the general pediatric ambulatory clinic. At the conclusion of each clinic, attendings completed brief student evaluation cards. Traditionally, student and attending schedules were created independently, resulting in transient supervisory relationships and dissatisfaction with clinical engagement, feedback, and evaluation. OUTCOME: Seventy-three percent (43/59) of the students completed the survey. Ten general ambulatory attendings collectively completed 87.5% (35/40) of the monthly surveys. Continuity students received significantly more narrative evaluation comments (10.6 vs. 5.8, p <. 001) from general ambulatory clinic attendings and were more likely to have at least one general ambulatory clinic attending endorse being able to provide meaningful feedback and evaluation (n = 29, 100% vs. n = 20, 66.7%, p <. 001). Continuity students were also more likely to endorse being able to ask at least one of these attendings for a letter of recommendation (71.4% vs. 9.1%, p <. 001) and to have at least one general ambulatory clinic attending endorse being able to provide a meaningful letter of recommendation if asked (62.1% vs. 3.3%, p <. 001). Students (88.4%) and attendings (85.7%) preferred the continuity-enhanced schedule. The most frequent theme of both student and attending free-text survey remarks were relationships and assessment. LESSONS LEARNED: Intentional scheduling of clerkship students to enhance preceptor continuity resulted in significant positive outcomes echoing the relationship-based educational benefits of longitudinal clerkships, particularly in regards to student assessment and feedback. Clerkship directors and other medical educators should consider implementing small changes within block clerkships to maximize student-preceptor continuity.

Nonsurgical management of cardiac missiles.

Modern air-powered pellet guns are capable of propelling their projectiles at velocities of 250 to 930 ft/s depending on their propulsion system-rivaling traditional small caliber firearms in the potential for serious soft tissue injuries. Management decisions regarding thoracic/cardiac pellet gun injuries must be based on the presentation and stability of the patient and the location of the retained pellet. We present a report of the nonsurgical management of an 8-year-old girl with a retained pericardial pellet and small stable effusion.

Bartonella endocarditis in a child with tetralogy of Fallot complicated by PR3-ANCA positive serology, autoimmune hemolytic anemia, and acute kidney injury.

Although the role of ANCA in infective endocarditis is unclear, Bartonella henselae has been implicated as the culprit in cases of PR3-ANCA positive subacute bacterial endocarditis (SBE) with glomerulonephritis. In this case, a Coombs-positive autoimmune hemolytic anemia and glomerulonephritis accompanied a PR3-ANCA positive SBE caused by Bartonella henselae.

Efficacy of a Web-Based Oral Case Presentation Instruction Module: Multicenter Randomized Controlled Trial.

OBJECTIVE: Effective self-directed educational tools are invaluable. Our objective was to determine whether a self-directed, web-based oral case presentation module would improve medical students' oral case presentations compared to usual curriculum, and with similar efficacy as structured oral presentation faculty feedback sessions. METHODS: We conducted a pragmatic multicenter cluster randomized controlled trial among medical students rotating in pediatric clerkships at 7 US medical schools. In the clerkship's first 14 days, subjects were instructed to complete an online Computer-Assisted Learning in Pediatrics Program (CLIPP) oral case presentation module, an in-person faculty-led case presentation feedback session, or neither (control). At the clerkship's end, evaluators blinded to intervention status rated the quality of students' oral case presentations on a 10-point scale. We conducted intention-to-treat multivariable analyses clustered on clerkship block. RESULTS: Study participants included 256 CLIPP (32.5%), 263 feedback (33.3%), and 270 control (34.2%) subjects. Only 51.1% of CLIPP subjects completed the assigned presentation module, while 98.5% of feedback subjects participated in presentation feedback sessions. Compared to controls, oral presentation quality was significantly higher in the feedback group (adjusted difference in mean quality, 0.28; 95% confidence interval, 0.08, 0.49) and trended toward being significantly higher in the CLIPP group (0.19; 95% confidence interval, -0.006, 0.38). The quality of presentations in the CLIPP and feedback groups was not significantly different (-0.10; 95% confidence interval, -0.31, 0.11). CONCLUSIONS: The quality of oral case presentations delivered by students randomized to complete the CLIPP module did not differ from faculty-led presentation feedback sessions and was not statistically superior to control.

Pediatric interventional cardiology in the United States is dependent on the off-label use of medical devices.

OBJECTIVE: A substantial unmet medical device need exists in pediatric care. As a result, the off-label use of approved devices is routine in pediatric interventional cardiology, but the extent and nature of this practice has not been previously described. The purpose of this study, therefore, is to evaluate the prevalence and nature of off-label cardiac device use in an active pediatric interventional program in the United States. STUDY DESIGN: This study is a retrospective review of all interventional cardiac procedures performed at our institution from July 1, 2005 to June 30, 2008. Diagnostic (noninterventional) catheterizations, myocardial biopsies, invasive electrophysiology studies, and studies involving investigational devices were excluded. Interventions performed were compared with the manufacturer's labeled indications for each device. RESULTS: During this 3-year period, 473 patients (median age 4.1 years) underwent 595 transcatheter interventions. An approved device was utilized for an off-label application in 63% of patients, and in 50% of all interventions performed. The most frequent off-label procedures were stent implantations (99% off-label), balloon dilations (78% off-label), and coil embolizations (29% off-label). In contrast, the off-label use of septal and ductal occluders was relatively uncommon. CONCLUSIONS: In our routine (noninvestigational) practice of pediatric interventional cardiology, 63% of patients underwent procedures utilizing medical devices for off-label indications. These data underscore the need to enhance cardiac device review and approval processes in the United States to include pediatric applications.

Kawasaki disease without fever.

Kawasaki disease (KD) characteristically presents with prolonged, remittent fever in addition to other clinical findings. We report the case of a 3-month-old boy who developed characteristic manifestations of KD and coronary aneurysms in the absence of fever. This case report underlines the difficulty to diagnose KD in young infants.

Novel fibrillin 1 mutation in a case of neonatal Marfan syndrome: the increasing importance of early recognition.

Neonatal Marfan syndrome (MFS) is a severe form of classic MFS caused by mutations in a specific region of the fibrillin 1 gene (FBN1). We report a case of an infant with neonatal MFS who presented with flexion contractures in utero and severe skeletal and cardiovascular manifestations at birth. A novel de novo missense mutation in exon 26 of FBN1 was demonstrated. Because of potential new therapies, it is increasingly important to recognize neonatal MFS in utero as well as shortly after birth to initiate the appropriate diagnostic work-up and management.
