RESUMEN
BACKGROUND: To date, there are limited radiation dose data on CT-guided procedures in pediatric patients. OBJECTIVE: Our goal was to quantify the radiation dose associated with pediatric CT-guided drain placement and follow-up drain evaluations in order to estimate effective dose. MATERIALS AND METHODS: We searched the electronic medical record and picture archiving and communication system (PACS) to identify all pediatric (<18 years old) CT-guided drain placements performed between January 2008 and December 2013 at our institution. We compiled patient data and radiation dose information from CT-guided drain placements as well as pre-procedural diagnostic CTs and post-procedural follow-up fluoroscopic abscess catheter injections (sinograms). Then we converted dose-length product, fluoroscopy time and number of acquisitions to effective doses using Monte Carlo simulations and age-appropriate conversion factors based on annual quality-control testing. RESULTS: Fifty-two drainages were identified with mean patient age of 11.0 years (5 weeks to 17 years). Most children had diagnoses of appendicitis (n=23) or inflammatory bowel disease (n=11). Forty-seven patients had diagnostic CTs, with a mean effective dose of 7.3 mSv (range 1.1-25.5 mSv). Drains remained in place for an average of 16.9 days (range 0-75 days), with an average of 0.9 (0-5) sinograms per patient in follow-up. The mean effective dose for all drainages and follow-up exams was 5.3 mSv (0.7-17.1) and 62% (32/52) of the children had effective doses less than 5 mSv. CONCLUSION: The majority of pediatric patients who have undergone CT-guided drain placements at our institution have received total radiation doses on par with diagnostic ranges. This information could be useful when describing the dose of radiation to parents and providers when CT-guided drain placement is necessary.

BACKGROUND: Alcohol misuse, which includes the full spectrum from risky drinking to alcohol dependence, is a leading cause of preventable death in the United States. PURPOSE: To evaluate the benefits and harms of behavioral counseling interventions for adolescents and adults who misuse alcohol. DATA SOURCES: MEDLINE, EMBASE, the Cochrane Library, CINAHL, PsycINFO, International Pharmaceutical Abstracts, and reference lists of published literature (January 1985 through January 2012, limited to English-language articles). STUDY SELECTION: Controlled trials at least 6 months' duration that enrolled persons with alcohol misuse identified by screening in primary care settings and evaluated behavioral counseling interventions. DATA EXTRACTION: One reviewer extracted data and a second checked accuracy. Two independent reviewers assigned quality ratings and graded the strength of the evidence. DATA SYNTHESIS: The 23 included trials generally excluded persons with alcohol dependence. The best evidence was for brief (10- to 15-minute) multicontact interventions. Among adults receiving behavioral interventions, consumption decreased by 3.6 drinks per week from baseline (weighted mean difference, 3.6 drinks/wk [95% CI, 2.4 to 4.8 drinks/wk]; 10 trials; 4332 participants), 12% fewer adults reported heavy drinking episodes (risk difference, 0.12 [CI, 0.07 to 0.16]; 7 trials; 2737 participants), and 11% more adults reported drinking less than the recommended limits (risk difference, 0.11 [CI, 0.08 to 0.13]; 9 trials; 5973 participants) over 12 months compared with control participants (moderate strength of evidence). Evidence was insufficient to draw conclusions about accidents, injuries, or alcohol-related liver problems. Trials enrolling young adults or college students showed reduced consumption and fewer heavy drinking episodes (moderate strength of evidence). Little or no evidence of harms was found. LIMITATIONS: Results may be biased to the null because the behavior of control participants could have been affected by alcohol misuse assessments. In addition, evidence is probably inapplicable to persons with alcohol dependence and selective reporting may have occurred. CONCLUSION: Behavioral counseling interventions improve behavioral outcomes for adults with risky drinking. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

RATIONALE AND OBJECTIVES: Designed to provide broad-based training in all aspects of imaging, the diagnostic radiology residency program must provide educational experiences that not only provide technical training, but also meet accreditation standards. With the breadth of material to cover during training, carefully orchestrated educational experiences must be planned. This manuscript reports a breast imaging boot camp curriculum with longitudinal outcomes, highlighting the boot camp's pedagogy and adaptability for residencies to meet the challenges of the Accreditation Council for Graduate Medical Education (ACGME) Diagnostic Radiology Milestones Second Revision. MATERIALS AND METHODS: Breast block curriculum analysis, faculty leader preparation, and evaluation of all objective external benchmarks were undertaken commencing in 2012 and continuing through 2019. Specific curriculum changes include fundamental didactic lectures and self-study education modules, hands-on simulation activities, and team-building time. Upon publication of The Diagnostic Radiology Milestones Second Revision December 2019, all competencies were assessed in the context of the boot camp resident educational experiences. RESULTS: Following curriculum implementation, resident anonymous evaluation scores of the breast block, resident in-training examination scores, American Board of Radiology Core examination scores, and radiology residency educational website analytics all increased immediately and significantly. The curriculum meets twenty-four Diagnostic Milestones per participating resident when mapped against the newly implemented ACGME requirements. CONCLUSIONS: Breast imaging boot camp is a successful innovative curriculum, readily meeting our learners' needs in all objective benchmarks. Further, the adaptable model has the potential to play important roles in assisting residencies to meet the challenges of the ACGME Diagnostic Radiology Milestones Second Revision July 1, 2020 implementation date.

Bloom's Taxonomy, an integral component of learning theory since its inception, describes cognitive skill levels in increasing complexity (Remember, Understand, Apply, Analyze, Evaluate, and Create). Considering Bloom's Taxonomy when writing learning objectives and lecture material, teaching residents at the workstation and creating multiple choice questions can increase an educator's effectiveness. The incorporation of higher Bloom levels aids in cultivating critical thinking skills vital to image interpretation and patient care, and becomes increasingly important as the radiologist's role evolves with the continued development of artificial intelligence. Following established tenets of multiple choice question writing, involving trainees in the question writing process, and incorporating audience response systems into lectures are all strategies in which higher Bloom level skills can be accomplished.
