Pediatric residency program handover: before and after the ACGME requirement.

OBJECTIVE: To determine what changes occurred in pediatric residency programs with regards to handover education and assessment before and after the Accreditation Council for Graduate Medical Education (ACGME) requirement mandating monitoring safe handover practices in July 2011. METHODS: We sent surveys at 2 time periods to all pediatric program directors in the United States, as identified from a list provided by the Association of Pediatric Program Directors. Respondents were asked about their program demographics, whether they had handover curricula, how trainees were taught to perform handovers, and perceived barriers to effective handover. RESULTS: Response rates were 58% in both survey years. After the ACGME requirement, only 1 of 3 of programs reported a handover curriculum with goals, objectives, and assessment tools. There was a statistically significant increase in the percentage of those responding that resident handover education primarily occurred by role modeling (66% vs 82%; P < .05). Other learners (visiting residents, medical students) also continued to learn handover skills by role modeling (55% vs 56%; P = NS). Lack of feedback and interruptions were recognized as barriers to successful handover by program directors in both survey years. CONCLUSIONS: There is a continued need for handover curricula with didactic and practical components as well as assessment pieces within pediatric residency programs. Barriers to effective handover such as lack of feedback and interruptions continue to be major problems. There is a lack of faculty ownership and interest in learner handover that may affect long-term successes. Because role modeling continues to be the main way in which trainees learn handover, specific attention should be given to teach role-modeling techniques.

Occult cardiotoxicity in childhood cancer survivors exposed to anthracycline therapy.

BACKGROUND: More than 50% of >270 000 childhood cancer survivors in the United States have been treated with anthracyclines and are therefore at risk of developing cardiotoxicity. Cardiac magnetic resonance (CMR) has demonstrated utility to detect diffuse interstitial fibrosis and changes in regional myocardial function. We hypothesized that CMR would identify occult cardiotoxicity characterized by structural and functional myocardial abnormalities in a cohort of asymptomatic pediatric cancer survivors with normal global systolic function. METHODS AND RESULTS: Forty-six long-term childhood cancer survivors with a cumulative anthracycline dose ≥200 mg/m(2) and normal systolic function were studied 2.5 to 26.9 years after anthracycline exposure. Subjects underwent transthoracic echocardiography, CMR with routine cine acquisition, tissue characterization, and left ventricular strain analysis using a modified 16-segment model. Extracellular volume was measured in 27 subjects, all of whom were late gadolinium enhancement negative. End-systolic fiber stress was elevated in 45 of 46 subjects. Low average circumferential strain magnitude (εcc) -14.9±1.4; P<0.001, longitudinal strain magnitude (εll) -13.5±1.9; P<0.001, and regional peak circumferential strain were seen in multiple myocardial segments, despite normal global systolic function by transthoracic echocardiography and CMR. The mean T1 values of the myocardium were significantly lower than that of control subjects at 20 minutes (458±69 versus 487±44 milliseconds; P=0.01). Higher mean extracellular volume was observed in female subjects (0.34 versus 0.22; P=0.01). CONCLUSIONS: Asymptomatic postchemotherapy pediatric patients have abnormal myocardial characteristics and strain parameters by CMR despite normal global cardiac function by standard transthoracic echocardiography and CMR measures.

Reinfection and relapse in early Lyme disease.

To determine whether recurrent episodes of appropriately treated Lyme disease are caused by reinfection or relapse, we monitored pertinent clinical manifestations and serology of residents of an endemic site each year for 14 years. Of 253 episodes of early Lyme disease recorded among 213 residents, we observed 40 recurrent episodes. Virtually all included an erythema migrans (EM) rash that appeared at body sites that differed from those of the initial rash, no subjects produced detectable levels of specific antibody between sequential episodes, all episodes occurred a year or more after the initial EM episode, and all occurred during late spring and early summer. People experiencing recurrent episodes tended to have frequent contact with vector ticks. Prompt administration of standard antibiotic therapy for early Lyme disease reliably eliminates persistent infection and prevents relapse.

Looking into the institutional review board: observations from both sides of the table.

Institutional review board (IRB) reviews offer the benefit of perspective afforded by the board's distance from the research and the research subjects. At the same time, distance from research subjects that is geographic, socioeconomic, cognitive, linguistic, and cultural can undermine the positive role of perspective. In addition, distance between IRB and investigators, largely a result of attitudes and communication, can prolong the review process and can obscure its message. The tension that often characterizes IRB-investigator relationships is due, in part, to variability in the application of federal regulations by IRBs across institutions and, on the part of investigators, inexperience, communication problems, and difficulties in anticipating the needs of their subjects. Contributing to the variability are the demographics and the culture of the IRB, attitudes that influence IRB-investigator relationships, and the adequacy of support from the institution. The effects of these factors on review decisions and on the performance of the human subjects protection system are largely unstudied. The movement for IRB accreditation is causing institutions to examine their overall research protection system and promises a more collaborative approach, where IRB and investigators accept their common charge to meet the needs of subjects and to improve the quality of research.
