Music plays an important role in the socialization of children and adolescents. Popular music is present almost everywhere, and it is easily available through the radio, various recordings, the Internet, and new technologies, allowing adolescents to hear it in diverse settings and situations, alone or shared with friends. Parents often are unaware of the lyrics to which their children are listening because of the increasing use of downloaded music and headphones. Research on popular music has explored its effects on schoolwork, social interactions, mood and affect, and particularly behavior. The effect that popular music has on children's and adolescents' behavior and emotions is of paramount concern. Lyrics have become more explicit in their references to drugs, sex, and violence over the years, particularly in certain genres. A teenager's preference for certain types of music could be correlated or associated with certain behaviors. As with popular music, the perception and the effect of music-video messages are important, because research has reported that exposure to violence, sexual messages, sexual stereotypes, and use of substances of abuse in music videos might produce significant changes in behaviors and attitudes of young viewers. Pediatricians and parents should be aware of this information. Furthermore, with the evidence portrayed in these studies, it is essential for pediatricians and parents to take a stand regarding music lyrics.

Objective Characterize and compare care in children with hemangiomas, who do or do not undergo airway procedures. Methods National retrospective cohort study of patients aged 0–18 with hemangiomas, from 33 freestanding United States pediatric hospital discharge records, 2001–2005. The main outcome measures were therapy, readmission and mortality. Results Of 2890 patients diagnosed with hemangiomas, 337 (12%) underwent airway procedures. Most airway procedures were for patients between ages 1 and 11 months. Patients with hemangiomas and airway procedures had more steroid use (80%), increased readmission (30%), and increased mortality (2%) compared to hemangioma patients without airway procedures. Procedures (i.e. laser, open surgery, tracheotomy) and age over 4 months in airway procedure patients were associated with decreased readmission. Increased readmissions were associated with systemic steroid administration. Conclusion Hemangioma patients who undergo airway procedures experience increased medical and surgical therapy compared to those who do not. Readmission is increased in patients with hemangiomas and airway procedures, but surgical intervention and age greater than 4 months decreased readmission.

OBJECTIVE: To test the independent association of adult language input, television viewing, and adult-child conversations on language acquisition among infants and toddlers. METHODS: Two hundred seventy-five families of children aged 2 to 48 months who were representative of the US census were enrolled in a cross-sectional study of the home language environment and child language development (phase 1). Of these, a representative sample of 71 families continued for a longitudinal assessment over 18 months (phase 2). In the cross-sectional sample, language development scores were regressed on adult word count, television viewing, and adult-child conversations, controlling for socioeconomic attributes. In the longitudinal sample, phase 2 language development scores were regressed on phase 1 language development, as well as phase 1 adult word count, television viewing, and adult-child conversations, controlling for socioeconomic attributes. RESULTS: In fully adjusted regressions, the effects of adult word count were significant when included alone but were partially mediated by adult-child conversations. Television viewing when included alone was significant and negative but was fully mediated by the inclusion of adult-child conversations. Adult-child conversations were significant when included alone and retained both significance and magnitude when adult word count and television exposure were included. CONCLUSIONS: Television exposure is not independently associated with child language development when adult-child conversations are controlled. Adult-child conversations are robustly associated with healthy language development. Parents should be encouraged not merely to provide language input to their children through reading or storytelling, but also to engage their children in two-sided conversations.

Although television viewing has been a normative activity for 50 years, the rise of infant viewing is a relatively recent phenomenon. The American Academy of Pediatrics discourages TV viewing in the first two years of life. The scientific evidence base supporting this recommendation has been meager but is growing. This article reviews the limitations of our current knowledge and argues in favor of additional focused research on media's effects on very young children.

Neonatal seizures are one of the most common neurological disorders in infants. However, the optimal treatment strategy for neonatal seizures remains controversial and there is little data regarding current treatment of neonatal seizures. In this study we describe the current treatment of neonatal seizures and variation in practice among 31 pediatric hospitals in the United States. We retrospectively identified 6099 infants hospitalized in the first month of life in one of 31 pediatric hospitals participating in the Pediatric Health Information System, with a discharge diagnosis of seizure. As expected, most treated infants received phenobarbital. However, there was significant interhospital variability for all treatments studied including any antiepileptic drug treatment, phenytoin treatment, antiepileptic drug treatment through discharge, number of antiepileptic drugs used, and treatment with pyridoxine (P < .001). These findings highlight the need for rigorous controlled outcome studies to determine optimal therapy for neonatal seizures and devise treatment standards.

To test the hypothesis that children enrolled in Medicaid managed care health plans that provide asthma-specific communication to providers would be more likely to have adequate asthma medication filling.We conducted a historical cohort study of 4498 children (2-17 years old) with moderate-severe asthma in Washington State and Tennessee Medicaid managed care programs from 2000 to 2002. Interviews with health plans were conducted to identify communication strategies health plans used to improve asthma care by providers in the plan. The main outcome measure was guideline-recommended filling of asthma preventer medications.Children in plans that provided specific feedback to providers about asthma quality and notified providers when children had an asthma-related event had the highest mean days plus or minus SE of filling in the 365-day follow-up period (164.6 +/- 13 days) compared with children in plans with neither (135.3 +/- 10.8 days; P.05). In children with the greatest asthma severity, enrollment in a plan with both features was associated with 27.1 additional days of filling (95% CI, 0.7-53.4 days) during the follow-up period.Health plan communication to providers was associated with increased preventer filling in children with moderate-severe asthma in 2 state Medicaid programs.

Objective To analyze the content of food and drink commercials aired during after-school hours on Spanish-language television. Study design We performed a content analysis of food and drink advertisements, evaluating product type, food category, and message content. All advertisements aired during after-school hours (3 to 9 p.m .) on 2 U.S. Spanish-language television stations were sampled over a 1-week period in the spring of 2006. Results We reviewed 60 hours of programming. Of the non-program content, 47% was for product advertisements, 15% (n = 153) of which was for food/drink. A mean of 2.5 food/drink commercials aired per hour (range 0-8), and the median duration was 30 seconds; 31% of food/drink commercials advertised fast food, and 27% advertised drinks, most (54%) of which were sugared. About one third (31%) of the food/drink commercials targeted children, 12% featured Latino celebrities, and 19% made reference to Latino culture. Only 16% of the food/drink commercials had health-related content. Conclusions Children viewing Spanish-language television in the United States after school are exposed to food and drink commercials, most of which advertise unhealthy foods, including fast food and sugared drinks. Food and beverage advertising on Spanish-language television may play an important role in the high risk of overweight among Latino children.

OBJECTIVES. The goals were to evaluate the use of touchscreen computer kiosks, containing only child health–promoting information, in urban, low-income, community settings and to characterize the users of these kiosks.METHODS. Three user-driven touchscreen computer kiosks were placed in low-income urban locations in Seattle, Washington, from March 2005 to October 2005. The locations included a public library, a Department of Motor Vehicles office, and a McDonald's restaurant. Users selected age-appropriate modules with prevention information and screening tools. Users entered the age of the child and were presented with age-appropriate modules. On exiting, users were asked to rate their experience and to provide basic demographic data.RESULTS. In total, there were 1846 kiosk sessions. Almost one half occurred at McDonald's. Seventy-eight percent of users identified themselves as first-time users. Users sought information for children of all ages. Sixty-one percent of first-time users explored 1 module. First-time users were most interested in television/media use (16%), smoke exposure (14%), attention-deficit/hyperactivity disorder screening (12%), and asthma assessment (11%). At-risk children were identified in 52% of sessions. Eighty-seven percent of first-time users who completed the asthma assessment had children whose asthma was uncontrolled. Twenty-eight percent of users responded to ≥1 question on the exit survey. Of those, 48% had less than a high school education, and 26% had never used the Internet. Approximately one half found the kiosk easy to use (57%) and the information easy to understand (55%); 66% said there was at least some new information. Fifty-five percent planned to try some of the things they had learned, and 49% intended to talk to their child's doctor about what they had learned.CONCLUSIONS. User-driven computer kiosks were used in community settings to obtain child health information. Users found the kiosks easy to use. Additional study on improving use and understanding the impact is needed.

BACKGROUND In the evaluation of infants with bronchiolitis there is little evidence to support the use of diagnostic testing, particularly complete blood counts (CBCs). However, the extent to which CBCs are ordered in the evaluation of infants with bronchiolitis is unknown. OBJECTIVES (1) To determine institutional variability in ordering of initial and repeat CBCs in infants hospitalized with bronchiolitis; (2) to examine the relationship between proportion of admissions with CBCs and mean hospital charges. METHODS We analyzed the Pediatric Health Information System database, which contains demographic and diagnostic data from 30 U.S. children's hospitals. We restricted our analysis to children less than 12 months old with a primary discharge diagnosis of bronchiolitis and an APR-DRG of bronchiolitis/asthma. We performed multivariate ANOVA to examine variability in initial and repeat CBC ordering across hospitals, controlling for potential confounders. We used stratified logistic regression to determine which factors were associated with repeat CBCs. We examined the relationship between proportion of admissions with CBCs and mean hospital charges using t tests. RESULTS 17,397 children were included in the analysis, and 48.2% had at least 1 CBC, whereas 7.8% had more than 1 CBC. The proportion of admissions with initial (23.2%-70.2%) and repeat (0%-18.6%) CBCs varied significantly across hospitals. Compared to those hospitals with the lowest proportion of admissions with CBCs, hospitals with higher proportions of CBCs had significantly higher mean hospital stay charges. CONCLUSIONS Given the potential downstream medical and financial consequences associated with CBC ordering in evaluation of infants with bronchiolitis, explanations for institutional variation warrant exploration.

Objective To assess how parents perceive long-term risks for developing obesity-related chronic health conditions. Methods A Web-based nationally representative survey was administered to 502 US parents with a 5- to 12-year-old child. Parents reported whether their child was most likely to be at a healthy weight or overweight, and the probability that their child would develop hypertension, heart disease, depression, or type 2 diabetes in adulthood. Responses of parents of children with overweight and obesity were compared to those of healthy-weight children using multivariate models. Results The survey had an overall response rate of 39.2%. The mean (SD) unadjusted parent predicted health risks were 15.4% (17.7%), 11.2% (14.7%), 12.5% (16.2%), and 12.1% (16.1%) for hypertension, heart disease, depression, and diabetes, respectively. Despite underperceiving their child's current body mass index class, parents of children with obesity estimate their children to be at greater risk for obesity-related health conditions than parents of healthy-weight children by 5 to 6 percentage points. Having a family history of a chronic disease, higher quality of care, and older parent age were also significant predictors of estimating higher risk probabilities. Conclusions Despite evidence that parents of children who are overweight may not perceive these children as being overweight, parents unexpectedly estimate greater future risk of weight-related health conditions for these children. Focusing communication about weight on screening for and reducing the risk of weight-related diseases may prove useful in engaging parents and children in weight management.

OBJECTIVE. The purpose of this work was to conduct a systematic review of experimental trials for the effects of television viewing by infants and preschoolers. METHODS. Searches were conducted as of January 2005 on several online bibliographic databases for the disciplines of medicine, psychology, education, and communications. Relevant bibliographies were also reviewed. The article contents were critically evaluated to determine whether they met inclusion criteria. Data were extracted from each included article regarding study methods and results. RESULTS. Twelve controlled trials met all of the criteria for inclusion in this review. All of the studies focused on the effect of television content rather than viewing time. The findings suggest that educational television programs are successful in broadening young children's knowledge, affecting their racial attitudes, and increasing their imaginativeness. There is insufficient experimental evidence for effects of viewing these programs on either children's prosocial behavior or their aggressive behavior. Finally, there is some evidence that viewing cartoons has a negative effect on children's attentional abilities. CONCLUSIONS. A number of gaps remain in the literature. Although the amount of time children spend viewing television raises concern, the studies presented here focus only on content. Despite the fact that infants are the fastest growing television market segment, the controlled trials only include children aged ≥3 years. Finally, the clinical utility of the findings are questionable given that most studies included small group sizes, all took place in nonnaturalistic settings, and all but 1 study only evaluated short-term effects of television viewing.

Although the amount of television that young children watch at home is well-described, to date no study has examined how much television preschool children watch in day care settings. We performed a cross-sectional analysis using the Profile of Child Care Settings Study, examining predictors of television viewing in center (n = 2089) and home-based (n = 583) child care programs. On average, preschool-aged children were reported to watch more than four times as much television while at home-based programs than at center-based programs (1.39 hours per day vs 0.36 hours per day); with significant differences between groups in the type of television content viewed, and in the proportions of programs in which no television viewing occurred at all. The proportion of programs where preschool-aged children watched no television during the child care day was 65% in center-based programs and 11% in home-based programs. The hours a program was open each day was associated with increased television viewing in both se...

BACKGROUND. The advent of tandem mass spectrometry has made it possible to test newborns for multiple conditions efficiently. It is not known how state newborn screening programs have changed screening practices in response to this technology and how it affects the number of false-positive test results.METHODS. We obtained data from the National Newborn Screening and Genetics Resource Center regarding the screening practices for each of the 50 states, to determine the number of mandated disorders added to state newborn screening panels between 1995 and 2005. Combining these data with reported specificities from the literature and the number of births in each state, we estimated the number of infants who would have received false-positive results through screening with tandem mass spectrometry in 2005.RESULTS. The average state mandated screening for 5 disorders in 1995 (range: 0–8 disorders). Wyoming was the only state that decreased its panel size over the next decade. Kansas and Texas were the only states that did not add disorders to their panels between 1995 and 2005; the average state added 19. Iowa, Minnesota, Mississippi, South Dakota, and Tennessee each added ≥40 disorders. Assuming that an individual test for a disorder had a specificity of 99.995%, we estimated that ∼2575 infants would have received false-positive results through screening with tandem mass spectrometry in 2005. If specificity was assumed to be 99.9%, then the number increased to >51000.CONCLUSIONS. State newborn screening programs have expanded dramatically in the past decade. Because the benefit of such testing may be unclear in some cases and because the number of infants who may receive false-positive results and may be labeled falsely as having disease is potentially sizeable, a more cautious approach is needed.

Objective To determine differences in case fatality rates between children with and without Down syndrome. Study design We used the Pediatric Health Information System (PHIS) database, which includes demographic and diagnostic data from freestanding children's hospitals. Using Poisson regression, we determined the risk of mortality from sepsis for children with Down syndrome, after controlling for potential confounding factors. Results A total of 35,645 patients met our inclusion criteria, of which 3936 (11%) died during hospitalization. Altogether, 620 of the included patients also had a diagnosis of Down syndrome; 106 (17%) of these died during hospitalization. Children with Down syndrome had significantly elevated risk of mortality (mortality rate ratio = 1.30; 95% confidence interval = 1.06 to 1.59) after adjusting for potential confounding factors including demographics, pathogens, and concomitant conditions. Conclusions Children with Down syndrome and sepsis have elevated risk of mortality. These findings have implications for treatment decisions, communications about prognosis, and future research.

Background: Providers' interest in satisfying parents may provide an impetus for unnecessary antibiotic use in children. Objectives: To determine (1) whether receipt of antibiotics at a visit for cough and cold symptoms was associated with increased satisfaction and (2) whether nonreceipt of antibiotics at an initial visit but subsequent receipt of antibiotics in the course of the same illness episode was associated with decreased satisfaction. Methods: Prospective cohort study of patients 2–10 years of age presenting to a university-affiliated pediatric clinic with cough and cold symptoms. Parents were enrolled at the index visit and then followed up by phone at least 7 days later (mean time to follow-up, 14.9 days). Satisfaction with the index visit on a 10 point scale was the primary outcome. The primary predictors were whether antibiotics were prescribed at the index visit and, if not, whether they were prescribed since that visit. Linear and median regression were used to adjust for income, child age, parental race and individual provider. Results: A total of 539 parents were enrolled in the study, and 378 (70%) completed follow-up interviews. The mean age of participating children was 4.67 years (SD 2.16). Overall 47% of patients received antibiotics at the index visit, and 8% of those that did not reported receiving them between the index visit and the follow-up assessment. In the regression model, receiving antibiotics at the index visit trended toward being associated with higher satisfactions scores (0.28; P = 0.08). Among those who did not receive antibiotics initially, receiving them subsequently was associated with significantly lower median satisfaction score for the index visit (−3.0; P Conclusions: Receiving antibiotics after an initial visit for cough and cold symptoms at which antibiotics were not prescribed is associated with decreased satisfaction. Use of contingency prescriptions may be an important intervention.

To determine pediatricians' routine screening urinalysis practices.This was a survey of a nationally representative sample of pediatricians practicing in the U.S. regarding their screening urinalysis practices in childhood.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.Many pediatricians routinely conduct screening urinalysis during childhood, frequently at ages not recommended by the American Academy of Pediatrics.

Objectives: To evaluate the validity of parents’ self reported home safety practices concerning smoke detectors, bike helmets, car seats, and water heater temperature. Setting: Parents of children 12 years old and under whose child had made at least one visit to a study clinic in the years 2000–2003. Methods: As part of a randomized controlled trial to improve patient provider communication and preventive practices, parents’ responses to telephone interview were compared with observations of safety practices during a home visit. Home visits were completed within nine weeks of the telephone interview. Parents were not told that the visit was part of a validation study and home visit observers were unaware of the interview responses. The authors calculated sensitivities, specificities, positive and negative predictive values, and their corresponding confidence intervals. Results: Sensitivity (0.78 to 0.98) and positive predictive values (0.75 to 1.00) were high for all items. Specificities and negative predictive values were more variable and the highest estimates (specificity 0.95 to 1.00, negative predictive value 0.95 to 0.97) were for car seat types. Conclusions: The results suggest that parent self report practice of certain injury prevention behaviors (owning a car seat, hot water temperatures) is reliable, whereas self reports on other practices (working smoke detectors, properly fitting bike helmets) may be overstated.

This study examined the association between early emotional support provided by parents and child internalizing and externalizing problems, using a nationally representative, longitudinal sample of 1361 children. Parental emotional support was assessed using the Home Observation for the Measurement of the Environment, incorporating both parent report and interviewer observation. We found that, controlling for child externalizing problems at age 6 years, parental emotional support at age 6 years was negatively related to child externalizing problems at age 8 years. A developmental model that assessed the timing of the emergence of this relationship was then analyzed by including parental emotional support at ages 2, 4, and 6 years as predictors of child externalizing problems at age 8 years. The developmental model suggested that less parental emotional support as early as age 2 years is associated with later externalizing problems in children. This study discusses the importance of very early parental emotional support in promoting positive child development. J Dev Behav Pediatr 26:267-275, 2005. Index terms: parenting, emotional support, child internalizing, child externalizing.

Background Tobacco use results in 500,000 premature deaths annually. Most smokers begin using tobacco before age 21, so the greatest impact on preventing smoking-related mortality is likely to come from campaigns targeting youths. This study estimates the cost-effectiveness of an anti-smoking media campaign and $1 per pack increase in cigarette taxes on the lifetime decrease in smoking-attributable mortality among the cohort of all 18-year-olds in the United States during the year 2000. Methods Cost-effectiveness analysis conducted from a societal perspective. Results The combined effects of a media campaign and $1 per pack tax increase will result in a societal savings of between $590,000 per life-year saved, at a 3% discount rate and $1.4 million per life year saved, at a 7% discount rate. Conclusions A media campaign and $1 per pack cigarette tax increase will reduce overall smoking prevalence, significantly decrease smoking-attributable mortality, and decrease net societal costs.

Objectives. We know little about the variation in diagnosis and management of bronchiolitis. The objectives of this study were (1) to document variations in treatment and diagnostic approaches, lengths of stay (LOSs), and readmission rates and (2) to determine which potentially modifiable process of care measures are associated with longer LOSs and antibiotic usage. Methods. We used the Pediatric Health Information System, which includes demographic, diagnostic, and detailed patient-level data on 30 large children's hospitals. We examined infants who were younger than 1 year and hospitalized for bronchiolitis (October 2001–September 2003). Multivariate analysis of variance was used to determine whether the variance in the outcomes was hospital related after controlling for other covariates. Linear regression was used to model predictors of increased LOS. Logistic regression was used to model antibiotic usage. Analyses were stratified by age group ( Results. A total of 17397 patients were included in the analysis. The mean LOS was 2.97 days; 72% of patients received chest radiographs, 45% received antibiotics, and 25% received systemic steroids. The mean LOS varied considerably across hospitals (range: 2.40–3.90 days), and hospital remained a significant contributor to LOS variation after controlling for our covariates. Variations in the use of diagnostic tests and medications as well as readmission rates also existed and also remained significant after controlling for covariates. The factors associated with the greatest increases in LOS in the regression analyses included higher severity scores and use of antibiotics, bronchodilators, and corticosteroids. The strongest predictors of antibiotic use in the logistic regression analyses were higher severity scores and receipt of a blood or cerebrospinal fluid culture. Receiving a chest radiograph was a significant predictor of antibiotic use in older but not younger infants. Conclusions. Considerable, unexplained variation exists in the inpatient management of bronchiolitis. The development of national guidelines and controlled trials of new therapies and different management approaches are indicated.

Background.—A digital divide with respect to computer and Internet access has been noted in numerous studies and reports. Equally important to ownership is comfort with computers and Internet technology, and concerns about privacy of personal data. Objective.—To measure how households in a pediatric clinic vary in their attitudes toward computers, concerns about Internet confidentiality, and comfort using the Internet and whether these views are associated with household income or education. Design/Methods.—A phone survey was administered to a population-based sample of parents with children aged 0 to 11 years. All children received medical care from a community-based clinic network serving patients in King County, Wash. Results.—Eighty-eight percent of respondents used a computer once a week or more, and 83% of respondents reported favorable feelings toward computers. Although 97% of respondents were willing to share personal information over the Internet, many respondents considered data security important. While household income and parental education were associated with comfort and familiarity with computers, the effect is small. Respondents who already owned a computer and had Internet access did not differ in their perceptions according to socioeconomic or educational attainment. Conclusions.—Most families like using computers and feel comfortable using the Internet regardless of socioeconomic status. Fears about the digital divide's impact on the attitudes of parents toward computers or their comfort using the Internet should not be seen as a barrier to developing Internet-based health interventions for a pediatric clinic population.

Background Several systematic reviews of school-based smoking prevention trials have shown short-term decreases in smoking prevalence but have not examined long-term follow-up evaluation. The purpose of this study was to conduct a systematic review of rigorously evaluated interventions for school-based smoking prevention with long-term follow-up data. Methods We searched online bibliographic databases and reference lists from review articles and selected studies. We included all school-based, randomized, controlled trials of smoking prevention with follow-up evaluation to age 18 or 12th grade and at least 1 year after intervention ended, and that had smoking prevalence as a primary outcome. The primary outcome was current smoking prevalence (defined as at least 1 cigarette in the past month). Results The abstracts or full-text articles of 177 relevant studies were examined, of which 8 met the selection criteria. The 8 articles included studies differing in intervention intensity, presence of booster sessions, follow-up periods, and attrition rates. Only one study showed decreased smoking prevalence in the intervention group. Conclusions Few studies have evaluated the long-term impact of school-based smoking prevention programs rigorously. Among the 8 programs that have follow-up data to age 18 or 12th grade, we found little to no evidence of long-term effectiveness.

To conduct a population-based survey of television and other media usage in young children to determine (1) total media usage; (2) the proportion of children who have televisions in their bedrooms and who eat breakfast or dinner in front of the television; and (3) predictors of parental concern about the amount of television their child watches.Telephone survey administered to 1454 parents of children11 years old derived from a diverse clinic population.The mean age of the index child was 5.05 years. Mean daily reported child media use was as follows: television (1.45 hours; SD, 1.5); videos (1.1 hours; SD, 1.30); and computer games (0.54 hours; SD, 0.96). Thirty percent of parents reported that their child ate breakfast or dinner in front of the television in the past week, and 22% were concerned about the amount of television that their child watched. In multivariate linear regression, eating breakfast or dinner in front of the television in the past week was associated with increased hours of television viewing (0.38 hours [0.21, 0.54]) and video (0.19 hours [0.04, 0.34]). Having a television in a child's bedroom was associated with increased hours of television (0.25 hours [0.07, 0.43]), video viewing (0.31 hours [0.16, 0.47]), and computer games (0.21 hours [0.10, 0.32]). In general, higher parental education was associated with decreased hours of television and video but not computer games. Older children were 2 to 3 times more likely than younger children to have a television in their bedroom and to have eaten a meal in front of it in the past week. More educated parents were less likely to report that their child had a television in their bedroom and more likely to be concerned about the amount of television their child viewed.Combined video and computer game usage exceeded television usage. Both children of low- and high-income parents are at risk for certain behaviors associated with television usage. Parents whose children watched more television were more likely to be concerned about the amount of television their child viewed.

Objective. To test the hypothesis that late adolescent drinking behavior (ages 17–20) is associated with harmful and binge drinking in early adulthood (ages 30–31). Methods. We used the National Longitudinal Survey of Youth (NLSY), a nationally representative longitudinal data set. We used harmful and binge drinking at ages 17 to 20 to predict harmful and binge drinking at ages 30 to 31, stratifying for gender and controlling for confounders. Results. Data were available on harmful drinking at both the adolescent and the early adult age period for 3790 individuals and on binge drinking for 2387 individuals. Harmful drinking during adolescence was significantly associated with harmful drinking at ages 30 to 31 for men only. Among male adolescents, 14% of harmful drinkers continued harmful drinking at ages 30 to 31, compared with 4% of nonharmful drinkers who became harmful drinkers. In Poisson regression models, binge drinking during adolescence was associated with binge drinking at ages 30 to 31 for both men and women, generating relative risks of 2.3 (95% confidence interval: 1.8–3.0) and 3.0 (95% confidence interval: 2.4–4.8), respectively. Half of binge-drinking male adolescents and one third of binge-drinking female adolescents engaged in binge drinking into early adulthood, compared with 19% for non–binge-drinking male adolescents and 8% of non–binge-drinking female adolescents. Conclusions. Problem drinking during adolescence is associated with problem drinking in early adulthood. Efforts to prevent and treat adolescent problem drinking could have an impact on the progression of alcohol-related disease.

Background Tobacco is the leading cause of death in the United States. The majority of people who smoke begin before age 18. Objective Determine the number of smoking-attributable deaths and years of potential life lost (YPLL) in adults that might be saved through interventions to reduce smoking prevalence among children and adolescents. Methods Calculation of the smoking-attributable mortality and years of potential life lost by age 85 among the cohort of people aged 18 in 2000. Results By age 85, there would be 127,670 smoking-attributable deaths among women and 284,502 deaths among men, for a total 412,172 smoking-attributable deaths in the United States among the cohort of 3,964,704 people aged 18 years alive in 2000. Through large-scale multimedia campaigns and a $1 increase in the price per pack of cigarettes, smoking prevalence could be reduced by 26% and would result in an annual savings of 108,466 lives and 1.6 million YPLL. Conclusions Interventions to decrease smoking prevalence among children and adolescents can have large effects on adult mortality.

Background. We recently found documentation discrepancies in 60% of resident daily-progress notes with respect to patient weight, medications, or vascular lines. To what extent information systems can decrease such discrepancies is unknown. Objective. To determine whether a point-of-care personal digital assistant (PDA)-based patient record and charting system could reduce the number of resident progress-note documentation discrepancies in a neonatal intensive care unit (NICU). Design/Methods. We conducted a before-and-after trial in an academic NICU. Our intervention was a PDA-based patient record and charting system used by all NICU resident physicians over the study period. We analyzed all resident daily-progress notes from 40 randomly selected days over 4 months in both the baseline and intervention periods. Using predefined reference standards, we determined the accuracy of recorded information for patient weights, medications, and vascular lines. Logistic and Poisson regression were used in analyses to control for potential confounding factors. Results. A total of 339 progress notes in the baseline period and 432 progress notes in the intervention period were reviewed. When controlling for covariates in the regression, there were significantly fewer documentation discrepancies of patient weights in notes written by using the PDA system (14.4%–4.4% of notes; odds ratio [OR]: 0.29; 95% confidence interval [CI]: 0.15–0.56). When using the PDA system, there were no significant changes in the numbers of notes with documentation discrepancies of medications (27.7%–17.1% of notes; OR: 0.63; 95% CI: 0.35–1.13) or vascular lines (33.6%–36.1% of notes; OR: 1.11; 95% CI: 0.66–1.87). Conclusions. The use of our PDA-based point-of-care patient record and charting system showed a modest benefit in reducing the number of documentation discrepancies in resident daily-progress notes. Further study of PDAs in information systems is warranted before they are widely adopted.

Background. Personal digital assistants (PDAs) are being increasingly used in medical practice. Although they have been touted as having the ability to improve efficiency and safety, little is known about pediatricians’ use of and attitudes about PDAs. Objective. Our goals were to 1) determine the percentage of pediatricians using PDAs and computers, 2) determine perceived strengths and weaknesses of PDAs, and 3) explore characteristics associated with beliefs and use. Design/Methods. Pediatricians (2130) were selected randomly from the American Medical Association Physician Masterfile of US-licensed physicians. All participants were mailed a survey along with a prepaid return envelope and a $1 incentive. Up to 3 mailings were sent per participant. Results. Of eligible participants, 63.2% returned a survey. There were no significant differences between respondents and nonrespondents with respect to sex, type of practice, and present employment. Thirty-five percent of respondents currently use PDAs at work, and 40% currently use PDAs for personal use. Of those using PDAs, the most commonly used applications were for drug reference (80%), personal scheduling (67%), and medical calculations (61%). Few pediatricians are currently using PDAs for prescription writing (8%) or billing (4%). Users of PDAs were more likely to be male (adjusted odds ratio [AOR]: 2.29; 95% confidence interval [CI]: 1.64–3.19), in an urban community (AOR: 1.81; 95% CI: 1.30–2.55), in training (AOR: 2.64; 95% CI: 1.58–4.42), not in private practice (AOR: 1.47; 95% CI: 1.03–2.11), and a more recent graduate of medical school (AOR: 1.04 per year; 95% CI: 1.02–1.06). When controlling for covariates, those using PDAs were more likely to believe that PDAs can decrease medical errors (AOR: 2.22; 95% CI: 1.46–3.38) and increase efficiency (AOR: 2.40; 95% CI: 1.56–3.71). When compared with nonusers, users were less likely to view the small screen size (AOR: 0.53; 95% CI: 0.37–0.77) or system speed (AOR: 0.47; 95% CI: 0.26–0.84) as a problem but were significantly more likely to view memory as an issue (AOR: 3.48; 95% CI: 2.30–5.25). Conclusions. More than one third of pediatricians are using PDAs in clinical practice. There seems to be a general consensus among users that they have the potential to improve patient safety and streamline care. Future studies should explore means to utilize their potential.

Objective To conduct a systematic review of controlled trials for adolescent smoking cessation. Methods Online bibliographic databases were searched as of June 2002, and reference lists from review articles and the selected articles were also reviewed for potential studies. The methodology and findings of all retrieved articles were critically evaluated. Data were extracted from each article regarding study methods, intervention studied, outcomes measured, and results. Results The abstracts or full-text articles of 281 relevant studies were examined, of which six met the selection criteria. Included were three school-based studies, a study in pregnant adolescent girls, a hospital-based study, and a trial of laser acupuncture. All three of the school-based studies reported significant impacts on cessation rates, although only one of these was a randomized trial. None of the studies had follow-up times of >5.2 months. Conclusions There is very limited evidence demonstrating efficacy of smoking-cessation interventions in adolescents, and no evidence on the long-term effectiveness of such interventions. Smoking-cessation interventions that have proven most effective in adults, such as nicotine replacement and antidepressant use, have not been studied in adolescents in a controlled manner.

Objective To conduct a systematic review of randomized controlled trials of smoking prevention interventions for youth delivered via medical or dental providers' offices. Methods Online bibliographic databases were searched as of July 2002, and reference lists from review articles and the selected articles were also reviewed for potential studies. The methodology and findings of all retrieved articles were critically evaluated. Data were extracted from each article regarding study methods, intervention studied, outcomes measured, and results. Results The literature search returned 81 abstracts from MEDLINE and 49 from Cochrane Clinical Trials Registry (CCTR); of these, four articles met the inclusion criteria. Included were two studies conducted in primary care, and one each in dental and orthodontic offices. Only one study demonstrated a significant effect on smoking initiation; in that study, 5.1% of the intervention group and 7.8% of the control group reported smoking at 12-month follow-up (odds ratio= 0.63; 95% confidence interval, 0.44–0.91). None of the studies had follow-up times greater than 3 years. Conclusions There is very limited available evidence demonstrating efficacy of smoking prevention interventions in adolescents conducted in providers' offices and no evidence for long-term effectiveness of such interventions.

Context. Medical errors are common and potentially dangerous. Little is known about the role of documentation errors.Objective. To determine the proportion of resident physician progress notes that contained discrepancies, and to identify predictors of such discrepancies.Design/Methods. We conducted a retrospective cross-sectional chart review of resident physician progress notes over 40 random days in a 4-month period in a neonatal intensive care unit. Using predetermined criteria, we compared resident documentation of patient weights, medications, and vascular lines to other sources of information and recorded the numbers of documentation discrepancies.Results. There were discrepancies in 209 (61.7%) notes with respect to weight, vascular lines, or medications. Discrepancies occurred in the documentation of medications in 103 (27.7%) progress notes, of vascular lines in 119 (33.9%) progress notes, and of weights in 45 (13.3%) progress notes. Notes both omitted information regarding medications (18.2%) and vascular lines (13.9%) and documented inaccurate information regarding medications (18.6%) and vascular lines (30.1%). Patients with more medications or vascular lines, and with longer lengths of stay, were significantly more likely to have higher rates of documentation errors.Conclusions. Daily progress notes written by resident physicians in the neonatal intensive care unit often contain inaccurate, or omit pertinent, information. Alternative means or methods of documentation are warranted.

Context.—The importance of continuity of care as a means to promote care coordination remains controversial. Objective.—To determine if there is an association between having an objective measure of continuity of care and parental perception that care is well coordinated. Design.—Cross-sectional study. Setting and Population.—Seven hundred fifty-nine patients presenting to a primary care clinic completed surveys that included 5 items from the Components of Primary Care Index (CPCI) that relate to care coordination. Main Predictor Variable.—A continuity of care index (COC) that quantifies the degree of dispersion of care among providers. Main Outcome Measures.—Likelihood of parents reporting high scores on the care coordination domain as well as each of the 5 individual CPCI items related to care coordination. Results.—Greater continuity of care was associated with higher scores on the CPCI care-coordination domain (P Conclusions.—Greater continuity of primary care is associated with better care coordination as perceived by parents. Efforts to improve and maintain continuity may be justified.

Objective. To compare the continuity of care experienced by children who are in foster care with that of children who are not in foster care and are covered under Medicaid managed care and Medicaid fee-for-service (FFS).Methods. This retrospective cohort study used Medicaid claims/encounter data from Washington state. A total of 903 children who were in foster care and continuously enrolled in Medicaid for 24 months (1998–1999) were matched by age, gender, and rural/urban residence to 903 Medicaid managed care enrollees and 903 FFS beneficiaries who were not in foster care. Indices of the continuity of primary care experienced were calculated for each patient, and differences in continuity among the cohorts were assessed by running 3 multiple linear regression models for all possible pairings of cohorts, controlling for age, gender, rural/urban residence, and total number of primary care visits.Results. Foster care status was associated with decreased continuity of care relative to nonfoster managed care status (β = −0.12; 95% confidence interval [CI]: −0.15 to −0.09). Nonfoster FFS status was associated with lower continuity than managed care (β = −0.09; 95% CI: −0.12 to −0.06) and slightly higher continuity than foster care status (β = 0.03; 95% CI: 0.01–0.06).Conclusion. Although not dramatically different, continuity seems somewhat lacking for children in foster care. It is unclear to what degree the observed difference is confounded by the managed care/FFS distinction. As the enrollment of children in foster care into managed care plans has been controversial, efforts to promote the consistency of contact with providers while maintaining the flexibility afforded by FFS coverage seem warranted.

Context. End-of-life care is an important yet underdeveloped component of pediatric hospital services. Objectives. We sought 1) to describe the demographics of children who die in children's hospitals, 2) to describe the prevalence of complex chronic conditions (CCCs) among these cases, and 3) to test the hypotheses that cases with a greater number of CCC diagnoses experience longer periods both of mechanical ventilation and of hospitalization before death. Design and Methods. We identified all deaths of patients 0 to 24 years old that occurred in the 60 hospitals contributing discharge data to the National Association of Children's Hospitals and Related Institutions data consortium for the years 1991, 1994, and 1997. We classified discharge diagnoses into 9 major categories of CCCs (cardiovascular, neuromuscular, malignancy, respiratory, renal, metabolic, gastrointestinal, hematologic/immunologic, and other congenital/genetic). Results. Of the 13 761 deaths identified, 42% had been admitted between 0 and 28 days of life, 18% between 1 and 12 months, 25% between 1 and 9 years, and 15% between 10 and 24 years. Fifty-three percent were white, 20% were black, and 9% were Hispanic. The principal payer was listed as a governmental source for 42% and a private insurance company for 35%. Based on all the discharge diagnoses recorded for each case, 40% had no CCC diagnosis, 44% had diagnoses representing 1 major CCC category, 13% had diagnoses representing 2 CCC categories, and 4% had diagnoses representing 3 or more CCC categories. Among cases that had no CCC diagnoses, the principal diagnoses were related to prematurity and newborn disorders for 32% of these cases, injuries and poisoning for 26%, and an assortment of acute and infectious processes for the remaining 42%. Mechanical ventilation was provided to 66% of neonates, 40% of infants, 36% of children, and 36% of adolescents. Cases with CCCs were more likely than non-CCC cases to have been mechanically ventilated (52% vs 46%), and to have been ventilated longer (mean: 11.7 days for CCC cases vs 4.8 days for non-CCC cases). The median duration of hospitalization was 4 days, while the mean was 16.4 days. After adjustment for age, sex, year, and principal payer, compared with patients with no CCC diagnoses, those with 1 major CCC category had a significantly lower hazard of dying soon after admission (hazard ratio [HR]: 0.60; 95% confidence interval [CI]: 0.57-0.62), those with 2 CCC categories even lower (HR: 0.53; 95% CI: 0.50-0.57), and those with 3 or more CCC categories the lowest hazard of rapid death (HR: 0.51; 95% CI: 0.46-0.57). This trend of diminishing hazard of rapid death was significant across the 3 groups of children with 1 or more CCCs. Conclusions. Children's hospitals care for a substantial number of dying patients, who differ widely by age and medical conditions. Children who die in the hospital with CCCs are more likely to experience longer periods of mechanical ventilation and hospitalization before death.

OBJECTIVES: Examine prospective associations between parent-reported early childhood self-regulation problems and media exposure (television and video viewing) at 2 years. We hypothesized that children with poor self-regulation would consume more media, possibly as a parent coping strategy. METHODS: We used data from 7450 children in the Early Childhood Longitudinal Study–Birth Cohort. When children were 9 months and 2 years old, parents completed the Infant Toddler Symptom Checklist (ITSC), a validated scale of self-regulation. With daily media use at 2 years as our outcome, we conducted weighted multivariable regression analyses, controlling for child, maternal, and household characteristics. RESULTS: Children watched an average of 2.3 hours per day (SD 1.9) of media at age 2 years. Infants with poor self-regulation (9-month ITSC score ≥3) viewed 0.23 hour per day (95% confidence interval [CI] 0.12–0.35) more media at 2 years compared with those with 9-month ITSC score of 0 to 2; this remained significant in adjusted models (0.15 hour per day [95% CI 0.02–0.28]). Children rated as having persistent self-regulation problems (ITSC ≥3 at both 9 months and 2 years) were even more likely to consume media at age 2 (adjusted β 0.21 hour per day [95% CI 0.03–0.39]; adjusted odds ratio for >2 hours per day 1.40 [95% CI 1.14–1.71]). These associations were slightly stronger in low socioeconomic status and English-speaking households. CONCLUSIONS: Early childhood self-regulation problems are associated with mildly increased media exposure, even after controlling for important confounding variables. Understanding this relationship may provide insight into helping parents reduce their children’s screen time.

Context.The benefits of continuity of pediatric care remain controversial.Objective.To determine whether there is an association between having a continuous relationship with a primary care pediatric provider and decreased risk of emergency department (ED) visitation and hospitalization.Design.Retrospective cohort study.Setting and Population.We used claims data from 46 097 pediatric patients enrolled at Group Health Cooperative, a large staff-model health maintenance organization, between January 1, 1993, and December 31, 1998, for our analysis. To be eligible, patients had to have been continuously enrolled for at least a 2-year period or since birth and to have made at least 4 visits to one of the Group Health Cooperative clinics.Main Exposure Variable.A continuity of care (COC) index that quantifies the degree to which a patient has experienced continuous care with a provider.Main Outcome Measures.ED utilization and hospitalization.Results.Compared with children with the highest COC, children with medium continuity were more likely to have visited the ED (hazard ratio [HR]: 1.28 [1.20–1.36]) and more likely to be hospitalized (HR: 1.22 [1.09–1.38]). Children with the lowest COC were even more likely to have visited the ED (HR: 1.58 [1.49–1.66]) and to be hospitalized (HR: 1.54 [1.33–1.75]). These risks were even greater for children on Medicaid and those with asthma.Conclusions.Lower continuity of primary care is associated with higher risk of ED utilization and hospitalization. Efforts to improve and maintain continuity may be warranted.

Clinicians, health services researchers, and third-party payers, among others, are justifiably interested in the outcomes of pediatric medical care and are, therefore, supportive of research in this area. Pediatric populations pose some unique methodologic challenges for health services researchers. To date, however, many of the approaches, models, and techniques used in pediatric outcomes research have been imported uncritically from experience with adult populations. As a result, some of the most interesting and salient aspects of pediatric outcomes research have yet to be fully developed. These include the following: 1) the problems posed by the dynamics of childhood development, 2) an emphasis on health supervision, 3) the need to see children within the context of a family system and to appreciate the interrelatedness of child health domains, 4) the measurement of the effects of interventions that span sectors, and 5) the paucity of available data sources. This article reviews these problematic areas and argues for a broad conceptual definition of pediatric health, a systems approach to assessing outcomes, and increased interdisciplinary collaboration.

We assessed the reading habits of internists with and without epidemiological training because such information may help guide medical journals as they make changes in how articles are edited and formatted. In a 1998 national self-administered mailed survey of 143 internists with fellowship training in epidemiology and study design and a random sample of 121 internists from the American Medical Association physician master file, we asked about the number of hours spent reading medical journals per week and the percentage of articles for which only the abstract is read. Respondents also were asked which of nine medical journals they subscribe to and read regularly. Of the 399 eligible participants, 264 returned surveys (response rate 66%). Respondents reported spending 4.4 hours per week reading medical journal articles and reported reading only the abstract for 63% of the articles; these findings were similar for internists with and without epidemiology training. Respondents admitted to a reliance on journal editors to provide rigorous and useful information, given the limited time available for critical reading. We conclude that internists, regardless of training in epidemiology, rely heavily on abstracts and prescreening of articles by editors.

The effect of a journal's prestige on readers' impressions of an article is unknown. Two hypotheses were tested: first, that attribution of a study to a "high" prestige journal would be associated with improved impressions and attribution to a "low" prestige journal would be associated with diminished impressions; and second, that formal training in epidemiology and biostatistics would mitigate the effects of this journal attribution bias. The study was designed as a trial among a random sample of 264 internists. Participants were asked to read an article and an abstract from either the Southern Medical Journal (SMJ) or the New England Journal of Medicine (NEJM). Questionnaires were constructed that either attributed the article or abstract to its source or presented it as unattributed. After each article or abstract, respondents were asked to rate the quality of the study, the appropriateness of the methodology employed, the significance of the findings, and its likely effects on their practice. A 20-point impression score was created based on responses to these statements. The effect of attribution to a specific journal and formal epidemiology training on impression scores were assessed using linear regression. Of the 399 eligible participants, 264 questionnaires were returned (response rate 66%). Differences in impression scores associated with attribution of an article or abstract to the NEJM were.71 [95% C.I. (-.44-1.87)] and.50 [95% C.I. (-.87-1.87)] respectively; differences in impression scores associated with attribution of an article or abstract to the SMJ were -.12 [95% C.I. (-1.53-1.30)] and -.95 [95% C.I. (-2.41-.52)]. A stratified analysis demonstrated that epidemiology training did not meaningfully alter the effect of journal attribution on participants' impression scores. If journal attribution bias exists, it is likely to exert small and clinically insignificant effects when physicians read articles carefully. Formal training in epidemiology and biostatistics does not appear to alter these results.

Objective:To conduct a systematic review of rigorously evaluated treatments for infant colic.Methods.Online bibliographic databases were searched for the term “colic” in articles classified as clinical trials or randomized controlled trials and conducted in infants. Reference lists from review articles, meta-analyses, and the selected articles were also reviewed for potential studies. The abstracts or full-text articles of 57 relevant studies were examined, of which 22 met the selection criteria. The methodology and findings of all retrieved articles were critically evaluated. Data were extracted from each article regarding study methods, intervention studied, outcomes measured, and results.Results.Four of the interventions studied had data of adequate quality and statistically significant numbers needed to treat (NNT): hypoallergenic diet (NNT = 6), soy formula (NNT = 2), reduced stimulation (NNT = 2), and herbal tea (NNT = 3).Conclusions.There are some effective therapies for infant colic, but additional rigorous studies of existing and alternative therapies are needed.

Objectives.Advances in medical technology and public health are changing the causes and patterns of pediatric mortality. To better inform health care planning for dying children, we sought to determine if an increasing proportion of pediatric deaths were attributable to an underlying complex chronic condition (CCC), what the typical age of CCC-associated deaths was, and whether this age was increasing.Design.Population-based retrospective cohort from 1980 to 1997, compiled from Washington State annual censuses and death certificates of children 0 to 18 years old.Main Outcome Measures.For each of 9 categories of CCCs, the counts of death, mortality rates, and ages of death.Results.Nearly one-quarter of the 21 617 child deaths during this period were attributable to a CCC. Death rates for the sudden infant death syndrome (SIDS), CCCs, and all other causes each declined, but less so for CCCs. Among infants who died because of causes other than injury or SIDS, 31% of the remaining deaths were attributable to a CCC in 1980 and 41% by 1997; for deaths in children 1 year of age and older, CCCs were cited in 53% in 1980, versus 58% in 1997. The median age of death for all CCCs was 4 months 9 days, with substantial differences among CCCs. No overall change in the age of death between 1980 to 1997 was found (nonparametric trend test).Conclusions.CCCs account for an increasing proportion of child deaths. The majority of these deaths occur during infancy, but the typical age varies by cause. These findings should help shape the design of support care services offered to children dying with chronic conditions and their families.

Background. The benefits of continuity of care (COC) have not been firmly established for pediatric patients. Objective. To assess whether greater COC is associated with lower emergency department (ED) utilization. Setting. Outpatient teaching clinic at Children's Hospital and Regional Medical Center, Seattle, WA. Patients. All 785 Medicaid managed care children ages 0 to 19 years followed at Children's Hospital and Regional Medical Center between 1993 to 1997 who had at least four outpatient visits. Methods. Retrospective claims-based analysis. COC was quantified based on the number of different care providers in relation to the number of clinic visits. Results. Attending COC was significantly greater than resident COC. In a multiple event survival analysis, compared with those patients in the lowest tertile of attending COC, those in the middle tertile had 30% lower ED utilization (hazard ratio 0.70 [0.53–0.93]) and those in the highest tertile had 35% lower ED use (hazard ratio 0.65 [0.50–0.80]). Resident COC was not significantly associated with ED use. Conclusion. Greater COC with attending physicians in outpatient teaching clinics is associated with lower ED utilization.

Background. The increasing complexity of medical care and a desire to increase quality and control costs have led to growing use of clinical practice guidelines (CPGs). It is unclear how helpful these guidelines are to the practitioners expected to use them. We surveyed pediatricians about their knowledge and impressions of four well-publicized CPGs: the American Academy of Pediatrics' “Practice Parameter for Hyperbilirubinemia in Newborns” (hyperbilirubinemia), “A Guideline for the Management of Febrile Infants” (fever), the Agency for Health Care Policy and Research's “Guideline for Otitis Media With Effusion” (otitis), and the US Preventive Services Task Force Guide to Clinical Preventive Services (preventive care). Objectives. 1) What percentage of practicing pediatricians are aware of these guidelines? 2) How helpful do they find them? 3) What are practitioners' perceived limitations of these guidelines? 4) Have these guidelines affected provider behavior? 5) Are there features of a provider's training or practice that are associated with changing practice as a result of guidelines? Design. A national survey of 600 pediatricians selected at random from the American Medical Association master file. Results. A total of 300 of 555 eligible participants (54%) returned surveys. Of the respondents, 66% were aware of the hyperbilirubinemia guideline, 64% of the fever guideline, 50% of the otitis guideline, but only 16% knew of the preventive care guidelines. Mean helpfulness scores (1 to 10 scale, where 1 = “not at all helpful” and 10 = “extremely helpful”) ranged from 3.67 to 6.67 for the different guidelines. In terms of limitations, 15% to 33% of respondents reported that CPGs were “too cookbook,” 6% to 19% reported that they were “too time-consuming,” and 4% to 16% reported that they were “too cumbersome.” Additional reported limitations were believing that a guideline left no room for personal experience and judgment, concern of increased liability risk, and poor parental acceptance of CPG recommendations. The proportions reporting change in management as a result of a CPG were 28% for the hyperbilirubinemia guideline, 36% for the fever guideline, 19% for the preventive care guidelines, and 28% for the otitis guideline. Mean helpfulness scores reported by nonuniversity-affiliated physicians were significantly higher than those reported by university-affiliated physicians. In a regression model of respondents aware of a particular guideline, more recent graduation from medical school and increased helpfulness scores were associated with guideline-related behavior change. Conclusion. In their present form, CPGs are not perceived as very helpful by most practitioners. More recent medical school graduates and nonuniversity-affiliated physicians are more likely to find them helpful and more likely to change their behavior because of them.

Medical students and resident physicians spend much of their training engaged in transient, time-limited relationships with patients, families, and other care providers. This article offers a partial catalog of the problems that the evanescent nature of trainees' relationships with others creates in their lives, the strategies they often use to address these problems, and the deleterious consequences these strategies may have on their behavior and ethical development.
