Violence Exposure Among Women in the Sex Industry and Their Children in El Alto, Bolivia: A Comparative Cross-Sectional Study.

We conducted a comparative cross-sectional study to compare the prevalence of exposure to workplace violence and intimate partner violence (IPV) in 125 female sex workers (FSWs) and 125 age-matched control women working in other professions (non-FSWs) and their children in El Alto, Bolivia. Violence exposure was assessed using the Demographic Health Survey Domestic Violence Module. To determine associations between work type and violence exposure, we conducted multivariate logistic regression. One-third of working mothers experienced sexual IPV, regardless of their profession. FSWs experienced higher rates of severe physical IPV and workplace violence. Children of FSWs were approximately three times more likely to be exposed to violence in the workplace. In Bolivia, strategies to reduce exposure to violence within the home and in FSW workplaces are paramount to minimizing negative impacts on women and their children. These findings have implications for policies to improve education, living wages, and social interventions to prevent and mitigate violence against women and children.

Implementing and Assessing a Resident Diversity Council to Address the Need for a Diverse Clinical Workforce.

Importance: Minoritized racial and ethnic groups remain underrepresented in medicine (UIM) compared with the general population. Although many residency programs want to train a diverse group of individuals, methods for implementation are not fully established. Objective: To describe the implementation and restructuring of the Boston Combined Residency Program (BCRP) Diversity Council and evaluate the association between restructuring the BCRP Diversity Council and the number of UIM interns. Design, Setting, and Participants: A retrospective cohort study was conducted on a large academic pediatric residency program at Boston Children's Hospital and Boston Medical Center. Interns who matched in the BCRP from March 17, 2011, to March 18, 2021, were included. Interns who matched in an affiliated medicine-pediatrics residency were excluded because they are not universally exposed to the same recruitment efforts as individuals in the other BCRP tracks. Exposure: Because the BCRP Diversity Council was restructured in 2016, 2011-2016 was defined as the prerestructuring era and 2017-2021 as the postrestructuring era. Main Outcomes and Measures: The primary outcome was the proportion of interns who self-identified as UIM. Results: A total of 516 BCRP interns from 2011 to 2021 were included. A total of 62 individuals (12.0%) identified as racial and ethnic identities UIM (ie, American Indian/Alaska Native, Black/African American, Hispanic/Latino, and Native Hawaiian/Pacific Islander). During the 6-year prerestructuring Diversity Council era, 27 of the 275 BCRP interns (9.8%) were UIM; 35 of 241 BCRP interns (14.5%) were UIM during the 5-year restructured Diversity Council era (χ2 P = .10). Conclusions and Relevance: In this cohort study, the number of UIM interns was higher after the BCRP Diversity Council was restructured, although the difference was not statistically significant. As the magnitude of the Diversity Council's influence is multidimensional, perhaps studying additional aspects would have better captured its impact. The BCRP Diversity Council has expanded innovative recruitment initiatives, supported efforts to improve the resident experience, and collaborated with the residency and institutional leadership to promote an inclusive and antiracist learning environment.

Effect of a Novel Mindfulness Curriculum on Burnout During Pediatric Internship: A Cluster Randomized Clinical Trial.

IMPORTANCE: Mindfulness curricula can improve physician burnout, but implementation during residency presents challenges. OBJECTIVE: To examine whether a novel mindfulness curriculum implemented in the first 6 months of internship reduces burnout. DESIGN, SETTING, AND PARTICIPANTS: This pragmatic, multicenter, stratified cluster randomized clinical trial of a mindfulness curriculum randomized 340 pediatric interns to the intervention or control arm within program pairs generated based on program size and region. Fifteen US pediatric training programs participated from June 14, 2017, to February 28, 2019. INTERVENTIONS: The intervention included 7 hour-long sessions of a monthly mindfulness curriculum (Mindfulness Intervention for New Interns) and a monthly mindfulness refresher implemented during internship. The active control arm included monthly 1-hour social lunches. MAIN OUTCOMES AND MEASURES: The primary outcome was emotional exhaustion (EE) as measured by the Maslach Burnout Inventory 9-question EE subscale (range, 7-63; higher scores correspond to greater perceived burnout). Secondary outcomes were depersonalization, personal accomplishment, and burnout. The study assessed mindfulness with the Five Facet Mindfulness Questionnaire and empathy with the Interpersonal Reactivity Index subscales of perspective taking and empathetic concern. Surveys were implemented at baseline, month 6, and month 15. RESULTS: Of the 365 interns invited to participate, 340 (93.2%; 255 [75.0%] female; 51 [15.0%] 30 years or older) completed surveys at baseline; 273 (74.8%) also participated at month 6 and 195 (53.4%) at month 15. Participants included 194 (57.1%) in the Mindfulness Intervention for New Interns and 146 (42.9%) in the control arm. Analyses were adjusted for baseline outcome measures. Both arms' EE scores were higher at 6 and 15 months than at baseline, but EE did not significantly differ by arm in multivariable analyses (6 months: 35.4 vs 32.4; adjusted difference, 3.03; 95% CI, -0.14 to 6.21; 15 months: 33.8 vs 32.9; adjusted difference, 1.42; 95% CI, -2.42 to 5.27). None of the 6 secondary outcomes significantly differed by arm at month 6 or month 15. CONCLUSIONS AND RELEVANCE: A novel mindfulness curriculum did not significantly affect EE, burnout, empathy, or mindfulness immediately or 9 months after curriculum implementation. These findings diverge from prior nonrandomized studies of mindfulness interventions, emphasizing the importance of rigorous study design and suggesting that additional study is needed to develop evidence-based methods to reduce trainee burnout. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03148626.

MINdI: Mindfulness Instruction for New Interns.

Introduction: Trainee burnout has reached epidemic proportions and is increasing among physicians compared to non-health care professionals. Burnout is associated with depression and lower empathy, poor patient adherence to medical plans, and early physician retirement. Mindfulness is the quality of being nonjudgmental and present and has been shown to decrease physician burnout. Implementation of mindfulness curricula may decrease trainee burnout. Methods: Using Kern's six-step approach, we developed an easy-to-implement, facilitator-friendly mindfulness curriculum for pediatric interns. Curricular sessions were held monthly during preexisting 1-hour didactics over 6 months, facilitated by individuals without mindfulness experience. Learners were assessed on knowledge, attitudes, and behavior with postintervention surveys during a pilot in 2016. Qualitative data were used for curricular improvement resulting in the published curriculum. Results: Postcurriculum surveys from our pilot revealed that 69% of interns reported a more positive attitude toward mindfulness, while 62% reported having (1) greater knowledge about evidence supporting mindfulness, (2) improved knowledge on how to apply mindfulness techniques, and (3) the belief that techniques they had learned positively impacted their lives. Thirty-three percent endorsed using mindfulness techniques more frequently than they had prior to the start of the mindfulness curriculum. Discussion: Our novel curriculum provided longitudinal mindfulness training that meaningfully impacted trainee knowledge, behaviors, and attitudes. The curricular structure overcame the need for local topic experts and was feasible to implement within the confines of our complex program structure. Ongoing work will determine the impact of our curriculum on objective measures of burnout, empathy, and mindfulness.

Application Factors Associated With Clinical Performance During Pediatric Internship.

OBJECTIVE: Our goal was to identify aspects of residency applications predictive of subsequent performance during pediatric internship. METHODS: We conducted a retrospective cohort study of graduates of US medical schools who began pediatric internship in a large pediatric residency program in the summers of 2013 to 2017. The primary outcome was the weighted average of subjects' Accreditation Council for Graduate Medical Education pediatric Milestone scores at the end of pediatric internship. To determine factors independently associated with performance, we conducted multivariate linear mixed-effects models controlling for match year and Milestone grading committee as random effects and the following application factors as fixed effects: letter of recommendation strength, clerkship grades, medical school reputation, master's or PhD degrees, gender, US Medical Licensing Examination Step 1 score, Alpha Omega Alpha membership, private medical school, and interview score. RESULTS: Our study population included 195 interns. In multivariate analyses, the aspects of applications significantly associated with composite Milestone scores at the end of internship were letter of recommendation strength (estimate 0.09, 95% confidence intervals [CI]: 0.04, 0.15), numbers of clerkship honors (est. 0.05, 95% CI: 0.01-0.09), medical school ranking (est. 0.04, 95% CI: 0.08-0.01), having a master's degree (est. 0.19, 95% CI: 0.03-0.36), and not having a PhD (est. 0.14, 95% CI: 0.02-0.26). Overall, the final model explained 18% of the variance in milestone scoring. CONCLUSIONS: Letter of recommendation strength, clerkship grades, medical school ranking, and having obtained a Master's degree were significantly associated with higher clinical performance during pediatric internship.

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.

Feedback on oral presentations during pediatric clerkships: a randomized controlled trial.

OBJECTIVE: To measure the effects of participating in structured oral presentation evaluation sessions early in pediatric clerkships on students' subsequent presentations. METHODS: We conducted a single-blind, 3-arm, cluster randomized controlled trial during pediatric clerkships at Boston University School of Medicine, University of Maryland School of Medicine, Oregon Health & Science University, and Case Western Reserve University School of Medicine. Blocks of students at each school were randomly assigned to experience either (1) no formal presentation feedback (control) or a small-group presentation feedback session early in pediatric clerkships in which students gave live presentations and received feedback from faculty who rated their presentations by using a (2) single-item (simple) or (3) 18-item (detailed) evaluation form. At the clerkship end, overall quality of subjects' presentations was rated by faculty blinded to randomization status, and subjects reported whether their presentations had improved. Analyses included multivariable linear and logistic regressions clustered on clerkship block that controlled for medical school. RESULTS: A total of 476 participants were evenly divided into the 3 arms, which had similar characteristics. Compared with controls, presentation quality was significantly associated with participating in detailed (coefficient: 0.38; 95% confidence interval [CI]: 0.07-0.69) but not simple (coefficient: 0.16; 95% CI: -0.12-0.43) feedback sessions. Similarly, student self-report of presentation improvement was significantly associated with participating in detailed (odds ratio: 2.16; 95% CI: 1.11-4.18] but not simple (odds ratio: 1.89; 95% CI: 0.91-3.93) feedback sessions. CONCLUSIONS: Small-group presentation feedback sessions led by faculty using a detailed evaluation form resulted in clerkship students delivering oral presentations of higher quality compared with controls.

Why do children with ADHD discontinue their medication?

OBJECTIVE: To examine factors associated with parent-reported discontinuation of attention-deficit/hyperactivity disorder (ADHD) medication. METHODS: The authors conducted a telephone survey of parents of children 6 to 18 years old who had recently initiated ADHD medication according to insurance claims. RESULTS: A total of 127 parents of children with ADHD who had recently initiated ADHD medication completed the survey (43% response rate); 21% discontinued the ADHD medication. Parents of discontinuers were less likely to report having discussed the risks and benefits of ADHD medication with primary care providers (59% vs 82%, P = .03) and were more likely to report psychological side effects (58% vs 21%, P > .001). Multivariate analyses demonstrated that both psychological side effects and perceived inadequate medication effectiveness were associated with discontinuation. CONCLUSIONS: Many children discontinue ADHD medication within the first year, often because of psychological side effects or perceived inadequate medication effectiveness. Improved methods for psychological side effect management, setting realistic medication goals, and assessing therapeutic success are needed.

ADHD medications and risk of serious cardiovascular events in young and middle-aged adults.

CONTEXT: More than 1.5 million US adults use stimulants and other medications labeled for treatment of attention-deficit/hyperactivity disorder (ADHD). These agents can increase heart rate and blood pressure, raising concerns about their cardiovascular safety. OBJECTIVE: To examine whether current use of medications prescribed primarily to treat ADHD is associated with increased risk of serious cardiovascular events in young and middle-aged adults. DESIGN, SETTING, AND PARTICIPANTS: Retrospective, population-based cohort study using electronic health care records from 4 study sites (OptumInsight Epidemiology, Tennessee Medicaid, Kaiser Permanente California, and the HMO Research Network), starting in 1986 at 1 site and ending in 2005 at all sites, with additional covariate assessment using 2007 survey data. Participants were adults aged 25 through 64 years with dispensed prescriptions for methylphenidate, amphetamine, or atomoxetine at baseline. Each medication user (n = 150,359) was matched to 2 nonusers on study site, birth year, sex, and calendar year (443,198 total users and nonusers). MAIN OUTCOME MEASURES: Serious cardiovascular events, including myocardial infarction (MI), sudden cardiac death (SCD), or stroke, with comparison between current or new users and remote users to account for potential healthy-user bias. RESULTS: During 806,182 person-years of follow-up (median, 1.3 years per person), 1357 cases of MI, 296 cases of SCD, and 575 cases of stroke occurred. There were 107,322 person-years of current use (median, 0.33 years), with a crude incidence per 1000 person-years of 1.34 (95% CI, 1.14-1.57) for MI, 0.30 (95% CI, 0.20-0.42) for SCD, and 0.56 (95% CI, 0.43-0.72) for stroke. The multivariable-adjusted rate ratio (RR) of serious cardiovascular events for current use vs nonuse of ADHD medications was 0.83 (95% CI, 0.72-0.96). Among new users of ADHD medications, the adjusted RR was 0.77 (95% CI, 0.63-0.94). The adjusted RR for current use vs remote use was 1.03 (95% CI, 0.86-1.24); for new use vs remote use, the adjusted RR was 1.02 (95% CI, 0.82-1.28); the upper limit of 1.28 corresponds to an additional 0.19 events per 1000 person-years at ages 25-44 years and 0.77 events per 1000 person-years at ages 45-64 years. CONCLUSIONS: Among young and middle-aged adults, current or new use of ADHD medications, compared with nonuse or remote use, was not associated with an increased risk of serious cardiovascular events. Apparent protective associations likely represent healthy-user bias.

ADHD drugs and serious cardiovascular events in children and young adults.

BACKGROUND: Adverse-event reports from North America have raised concern that the use of drugs for attention deficit-hyperactivity disorder (ADHD) increases the risk of serious cardiovascular events. METHODS: We conducted a retrospective cohort study with automated data from four health plans (Tennessee Medicaid, Washington State Medicaid, Kaiser Permanente California, and OptumInsight Epidemiology), with 1,200,438 children and young adults between the ages of 2 and 24 years and 2,579,104 person-years of follow-up, including 373,667 person-years of current use of ADHD drugs. We identified serious cardiovascular events (sudden cardiac death, acute myocardial infarction, and stroke) from health-plan data and vital records, with end points validated by medical-record review. We estimated the relative risk of end points among current users, as compared with nonusers, with hazard ratios from Cox regression models. RESULTS: Cohort members had 81 serious cardiovascular events (3.1 per 100,000 person-years). Current users of ADHD drugs were not at increased risk for serious cardiovascular events (adjusted hazard ratio, 0.75; 95% confidence interval [CI], 0.31 to 1.85). Risk was not increased for any of the individual end points, or for current users as compared with former users (adjusted hazard ratio, 0.70; 95% CI, 0.29 to 1.72). Alternative analyses addressing several study assumptions also showed no significant association between the use of an ADHD drug and the risk of a study end point. CONCLUSIONS: This large study showed no evidence that current use of an ADHD drug was associated with an increased risk of serious cardiovascular events, although the upper limit of the 95% confidence interval indicated that a doubling of the risk could not be ruled out. However, the absolute magnitude of such an increased risk would be low. (Funded by the Agency for Healthcare Research and Quality and the Food and Drug Administration.).

Implementing a systems-oriented morbidity and mortality conference in remote rural Nepal for quality improvement.

PROBLEM: In hospitals in rural, resource-limited settings, there is an acute need for simple, practical strategies to improve healthcare quality. SETTING: A district hospital in remote western Nepal. KEY MEASURES FOR IMPROVEMENT: To provide a mechanism for systems-level reflection so that staff can identify targets for quality improvement in healthcare delivery. Strategies for change To develop a morbidity and mortality conference (M&M) quality improvement initiative that aims to facilitate structured analysis of patient care and identify barriers to providing quality care, which can subsequently be improved. DESIGN: The authors designed an M&M involving clinical and non-clinical staff in conducting root-cause analyses of healthcare delivery at their hospital. Weekly conferences focus on seven domains of causal analysis: operations, supply chain, equipment, personnel, outreach, societal, and structural. Each conference focuses on assessing the care provided, and identifying ways in which services can be improved in the future. EFFECTS OF CHANGE: Staff reception of the M&Ms was positive. In these M&Ms, staff identified problem areas in healthcare delivery and steps for improvement. Subsequently, changes were made in hospital workflow, supply procurement, and on-site training. LESSONS LEARNT: While widely practiced throughout the world, M&Ms typically do not involve both clinical and non-clinical staff members and do not take a systems-level approach. The authors' experience suggests that the adapted M&M conference is a simple, feasible tool for quality improvement in resource-limited settings. Senior managerial commitment is crucial to ensure successful implementation of M&Ms, given the challenging logistics of implementing these programmes in resource-limited health facilities.

Patient-centered design of an information management module for a personally controlled health record.

BACKGROUND: The development of health information technologies should be informed by iterative experiments in which qualitative and quantitative methodologies provide a deeper understanding of the abilities, needs, and goals of the target audience for a personal health application. OBJECTIVE: Our objective was to create an interface for parents of children with attention-deficit hyperactivity/disorder (ADHD) to enter disease-specific information to facilitate data entry with minimal task burden. METHODS: We developed an ADHD-specific personal health application to support data entry into a personally controlled health record (PCHR) using a three-step, iterative process: (1) a needs analysis by conducting focus groups with parents of children with ADHD and an heuristic evaluation of a prerelease version of a PCHR, (2) usability testing of an initial prototype personal health application following a "think aloud" protocol, (3) performance testing of a revised prototype, and (4) finalizing the design and functionality of the ADHD personal health application. Study populations for the three studies (focus groups and two usability testing studies) were recruited from organizations in the greater Boston area. Study eligibility included being an English- or Spanish-speaking parent who was the primary caretaker of a school-age child with ADHD. We determined subjects' health literacy using the Test of Functional Health Literacy in Adults (TOFHLA). We assessed subjects' task burden using the National Aeronautics and Space Administration (NASA) Task Load Index. To assess the impact of factors associated with the time spent entering data, we calculated Pearson correlation coefficients (r) between time on task and both task burden and subject characteristics. We conducted t tests to determine if time on task was associated with successful task completion. RESULTS: The focus groups included three cohorts: 4 Spanish-speaking parents with diverse health literacy, 4 English-speaking parents with lower health literacy, and 7 English-speaking parents with higher health literacy. Both the initial usability testing cohort (n = 10) and the performance-testing cohort (n = 7) included parents of diverse health literacy and ethnicity. In performance testing, the prototype PCHRs captured patient-specific data with a mean time on task of 11.9 minutes (SD 6.5). Task burden experienced during data entry was not associated with successful task completion (P = .92). Subjects' past computer experience was highly correlated with time on task (r = .86, P = .01), but not with task burden (r = .18, P = .69). The ADHD personal health application was finalized in response to these results by (1) simplifying the visual environment, (2) including items to support users limited by health literacy or technology experience, and (3) populating the application's welcome screen with pictures of culturally diverse families to establish a personal family-oriented look and feel. CONCLUSIONS: Our patient-centered design process produced a usable ADHD-specific personal health application that minimizes the burden of data entry.

Adverse drug event rates in six community hospitals and the potential impact of computerized physician order entry for prevention.

CONTEXT: Medications represent a major cause of harm and are costly for hospitalized patients, but more is known about these issues in large academic hospitals than in smaller hospitals. OBJECTIVE: To assess the incidence of adverse drug events (ADEs) in six community hospitals. DESIGN: Multicenter, retrospective cohort study. SETTING: Six Massachusetts community hospitals with 100 to 300 beds. PATIENTS: From 109,641 adult patients hospitalized from January 2005 through August 2006, a random sample of 1,200 patients was drawn, 200 per site. MAIN OUTCOME MEASURES: ADEs and preventable ADEs. METHODS: Presence of an ADE was evaluated using an adaptation of a trigger instrument developed by the Institute for Health Care Improvement. Independent reviewers classified events by preventability, severity, and potential for preventability by computerized physician order entry (CPOE). RESULTS: A total of 180 ADEs occurred in 141 patients (rate, 15.0/100 admissions). Overall, 75% were preventable. ADEs were rated as serious in 49.4% and life threatening in 11.7%. Patients with ADEs were older (mean age, 74.6 years, p < 0.001), more often female (60.3%, p = 0.61), and more often Caucasian (96.5%, p < 0.001) than patients without ADEs. Of the preventable ADEs, 81.5% were judged potentially preventable by CPOE. CONCLUSIONS: The incidence of ADEs in these community hospital admissions was high, and most ADEs were preventable, mostly through CPOE. These data suggest that CPOE may be beneficial in this setting.

Occurrence of adverse, often preventable, events in community hospitals involving nephrotoxic drugs or those excreted by the kidney.

Medication errors in patients with reduced creatinine clearance are harmful and costly; however, most studies have been conducted in large academic hospitals. As there are few studies regarding this issue in smaller community hospitals, we conducted a multicenter, retrospective cohort study in six community hospitals (100 to 300 beds) to assess the incidence and severity of adverse drug events (ADEs) in patients with reduced creatinine clearance. A chart review was performed on adult patients hospitalized during a 20-month study period with serum creatinine over 1.5 mg/dl who were exposed to drugs that are nephrotoxic or cleared by the kidney. Among 109,641 patients, 17,614 had reduced creatinine clearance, and in a random sample of 900 of these patients, there were 498 potential ADEs and 90 ADEs. Among these ADEs, 91% were preventable, 51% were serious, 44% were significant, and 4.5% were life threatening. Of the potential ADEs, 54% were serious, 44% were significant, 1.6% were life threatening, and 96.6% were not intercepted. All 82 preventable events could have been intercepted by renal dose checking. Our study shows that ADEs were common in patients with impaired kidney function in community hospitals, and many appear potentially preventable with renal dose checking.

Trends in otitis media treatment failure and relapse.

OBJECTIVES: The goals were to describe trends in acute otitis media, treatment failure, and relapse and in high-dose amoxicillin use and to determine whether treatment of acute otitis media with high-dose amoxicillin was associated with treatment failure or relapse. METHODS: We conducted a retrospective study of acute otitis media visits made between 1996 and 2004 by children 2 months to 12 years of age in a large group practice, using computerized data. We defined acute otitis media as an otitis media visit with antibiotics dispensed (preceded by 30 days without otitis media visits), treatment failure as initiation of treatment with a second antibiotic before the first prescription was finished, and relapse as initiation of antibiotic treatment after the first prescription was finished but within 30 days after the index acute otitis media episode. The primary independent measure was high-dose amoxicillin (>70 mg/kg per day). We evaluated changes over time and determined whether high-dose amoxicillin use was associated with otitis media treatment failure or relapse. RESULTS: We identified 111,335 acute otitis media visits over a 9-year period. The incidence of acute otitis media decreased from 385.1 visits per 1000 enrollees in 1996 to 188.8 visits per 1000 enrollees in 2004. The proportion of acute otitis media visits treated with high-dose amoxicillin increased from 1.7% in 1996 to 41.9% in 2004. Both otitis media treatment failure and relapse rates decreased from 1996 to 2004 (from 3.9% to 2.6% and from 9.2% to 8.9%, respectively). The odds of treatment failure or relapse did not differ between acute otitis media episodes treated with high-dose and low-dose amoxicillin. CONCLUSIONS: During the past decade, acute otitis media, treatment failure, and relapse became less common and high-dose amoxicillin use increased. However, high-dose amoxicillin treatment did not reduce the risk of individual infections resulting in adverse outcomes.

Preventing stroke among children with sickle cell anemia: an analysis of strategies that involve transcranial Doppler testing and chronic transfusion.

BACKGROUND: Transcranial Doppler ultrasonography can identify children with sickle cell anemia who are at elevated risk of stroke and may benefit from chronic transfusions. Uncertainty about the risk/benefit trade-offs of chronic transfusion has led some clinicians to decide not to offer transcranial Doppler ultrasonography screening. OBJECTIVES: Our goals were to (1) compare the projected benefits and risks of 6 primary stroke-prevention strategies, (2) estimate the optimal frequency of screening, and (3) identify key assumptions that influence the risk/benefit relationship. METHODS: We designed a decision model to compare 6 primary stroke-prevention strategies: (1) annual transcranial Doppler ultrasonography screening until age 16 with children at high risk of stroke receiving monthly transfusion for life; (2) annual transcranial Doppler ultrasonography until age 16 with transfusions until age 18; (3) biannual transcranial Doppler ultrasonography until age 16 with transfusions until age 18; (4) annual transcranial Doppler ultrasonography until age 10 with transfusion until age 18; (5) 1-time screening at age 2 with transfusion until age 18; and (6) no intervention. Assumptions were derived from the published literature. RESULTS: For a hypothetical cohort of 2-year-old children, the optimal strategy was transcranial Doppler ultrasonography screening annually until age 10 with children at high risk receiving monthly transfusions until age 18. The optimal strategy would prevent 32% of strokes predicted to occur without intervention. The optimal strategy led to benefits similar to more intensive screening and transfusion strategies but resulted in fewer adverse events. All the intervention strategies resulted in net losses in life expectancy, because the projected mortality averted by stroke prevention was outweighed by the projected increase in mortality from transfusion. Results were sensitive to adherence rates to iron-chelation therapy. CONCLUSIONS: The optimal stroke-prevention strategy was projected to be annual transcranial Doppler ultrasonography screening until age 10 with transfusion for children at high risk until age 18. Better adherence to chelation therapy would improve life expectancy in all intervention strategies.

Pediatricians' clinical decision making: results of 2 randomized controlled trials of test performance characteristics.

OBJECTIVE: To determine whether presenting test performance characteristics influences clinical management. DESIGN: Two questionnaire-based, randomized controlled trials. SETTING: Mailed surveys with 2 clinical vignettes. PARTICIPANTS: Randomly selected US pediatricians (N=1502). INTERVENTION: Vignette-specific, randomly assigned test information: no additional information (control), test characteristics (TC), or TC defined. In the pertussis vignette, the TC group received the direct fluorescent antibody test's sensitivity and specificity, and the TC defined group received the same information with definitions. In the urinalysis vignette, the TC group received the false-positive rate of persistent microhematuria in predicting renal disease, and the TC defined group received a definition of this information. MAIN OUTCOME MEASURES: In the pertussis vignette, diagnostic test choice and management of erythromycin therapy and hospital discharge plans. In the urinalysis vignette, serum laboratory testing and nephrology referral plans. RESULTS: Six hundred fifty-three participants (49.5% of those eligible) returned completed surveys. In the pertussis vignette, significantly more of the TC (73%) and TC defined (71%) groups ordered the best-performing test than did controls (21%) (P<.001 for both comparisons). Receiving test characteristics did not significantly affect erythromycin therapy or hospital discharge plans (P>or=.40). In the urinalysis vignette, the TC defined group referred to nephrology (30%) and checked laboratory tests (88%) significantly more often than did controls (19%, P=.01; 78%, P=.01, respectively), but the TC and control groups' testing and referral plans did not differ significantly (22% vs 19%, P=.36; 75% vs 78%, P=.48, respectively). CONCLUSION: Providing test performance characteristics influenced certain clinical decisions, sometimes in unexpected ways.

Systematic review of the relationship between early introduction of solid foods to infants and the development of allergic disease.

OBJECTIVE: To assess the evidence that early solid feeding (before age 4 months) increases the risk of allergic disease. DATA SOURCES: MEDLINE, the Cochrane Library, and the Drugs and Pharmacology section of EMBASE with key words "infant," "food," and "allergy." STUDY SELECTION: We found 2719 article citations and reviewed references of relevant articles. We critically evaluated the methods and results of articles that met inclusion criteria. We identified 13 studies that met inclusion criteria. There was only 1 controlled trial. DATA EXTRACTION: Allergic disease. DATA SYNTHESIS: Five studies found a positive association between early solid feeding and eczema, with a persistence of the association for 10 years in 1 study. Four studies found no association. One study found an association between early solid feeding and pollen allergy. We found no strong evidence to support the association between early solid feeding and the development of persistent asthma, persistent food allergy, allergic rhinitis, or animal dander allergy. CONCLUSIONS: Systematic review of available evidence suggests that early solid feeding may increase the risk of eczema. However, there are little data supporting an association between early solid feeding and other allergic conditions. Since many studies had problematic methods, additional controlled trials are needed to help guide physicians as they advise parents about the allergic risks of early introduction of solids.

Pediatricians' screening urinalysis practices.

OBJECTIVE: To determine pediatricians' routine screening urinalysis practices. STUDY DESIGN: This was a survey of a nationally representative sample of pediatricians practicing in the U.S. regarding their screening urinalysis practices in childhood. RESULTS: Of the 1502 pediatricians sampled, 653 eligible subjects participated, for an estimated response rate of 49.5%. The vast majority of participants (78%) routinely screen asymptomatic children with urinalysis in at least 1 age group. Pediatricians' screening urinalysis practice varies based on age group: 9% screen during infancy (<1 year), 60% screen during early childhood (1 up to 5 years), 55% screen during late childhood (5 to 12 years), and 58% screen during adolescence (13 to 20 years). The majority of pediatricians (58%) routinely screen more than 1 age group. Some 38% of the pediatricians surveyed believe that the overall health of children is improved by screening all asymptomatic children with urinalysis. CONCLUSIONS: Many pediatricians routinely conduct screening urinalysis during childhood, frequently at ages not recommended by the American Academy of Pediatrics.
