Risky Teen Driving in a Rural Southern State.

OBJECTIVE: Alabama is one of the five US states with the highest teen driving mortality. We recruited teen drivers to participate in a questionnaire regarding high-risk driving behaviors. METHODS: Teens were recruited from a large county school system to participate in a voluntary anonymous survey. Questions were taken in part from the National Youth Risk Behavior Survey. Descriptive statistics and odds ratios with 95% confidence intervals were calculated. RESULTS: A total of 1023 teen drivers participated (46% boys, 47% African American, 39% white, 6% Latino, and 7% other). In all, 526 students (52%) reported inconsistent seat belt use. Half of the teens surveyed reported using a cellular telephone while driving within the past 30 days (51%); 10% admitted to driving after drinking alcoholic beverages in the past 30 days, with 23% saying they had ridden with a driver who had been drinking. CONCLUSIONS: High-risk teen driving behaviors were reported by many of the participants in our study. The majority of teens surveyed do not routinely wear seatbelts. Common misperceptions still exist regarding seatbelts and should be a focus of future education. Future research should focus on parental behaviors and correcting misperceptions of young drivers.

Teen driving behaviors in a rural southern state.

OBJECTIVES: Motor vehicle crashes are the leading cause of death for teenagers. Alabama ranks fourth in the United States for teen crash fatalities. We sought to describe risky driving behaviors among teens in the rural areas of the state's most populous county. METHODS: A questionnaire was adapted from the Youth Risk Behavior Surveillance System. Each of the schools in Jefferson County, Alabama, participated in 2009 and 2010. Surveys were anonymous and data were entered into an Excel spreadsheet. Inclusion criteria were age 15 years and older. RESULTS: A total of 1399 surveys met inclusion criteria. A total of 52% of respondents were boys; 64% were white, 29% were African American, and 3% were Hispanic. Respondents were 15 (38%), 16 (36%), 17 (21%), and 18 (5%) years old. When asked about behaviors during driving in the last 30 days, 41% reported texting and 11% reported driving after drinking. Teens reported being a passenger in a car with the driver texting (67%) or after the driver had been drinking (27%) in the last 30 days. Overall, 58% reported not wearing a seatbelt; 13% reported driving after using drugs; 60% reported routinely exceeding the speed limit; 80% reported having discussed safe driving with a parent, but only 16% with their doctor; 25% had signed a safe driving contract; and 63% had taken a driving class. CONCLUSIONS: Many risky behaviors were identified for both teen drivers and passengers. A concerning number of teens are not receiving safe driving educational messages from parents, doctors, or driver's education classes. Some interventions have been instituted; however, more outreach efforts should be made to focus on strengthening driving laws and educating parents and teens.

Knowledge and management of sports concussions among coaches and certified athletic trainers in Alabama.

OBJECTIVES: To identify modifiable barriers in resources, knowledge, and management that may improve the care of young athletes with concussions in the state of Alabama. METHODS: An electronic survey was distributed to 2668 middle and high school coaches of contact sports in Alabama, and a paper survey was completed by 79 certified athletic trainers (ATCs) in 2010. Questions focused on their resource availability, knowledge of concussions based on the 2008 Consensus Statement on Concussion in Sport: the 3rd International Conference on Concussion in Sport (commonly known as the Zurich consensus statement), and management of concussions. RESULTS: A total of 402 (16% response rate) coaches and 55 ATCs (70% response rate) responded to the survey. This study highlights that ATC coverage often is limited to the high school level, football, and competitions. Both coaches and ATCs primarily use physicians to make return-to-play decisions, although coaches (43.7%) usually refer to primary care physicians, whereas ATCs (43.6%) refer to orthopedic or sports medicine physicians. The study also revealed that coaches and ATCs desire education and could expand concussion awareness by providing education to parents and athletes. No overall difference was seen in the knowledge and management of concussions between coaches and ATCs; however, ATCs were more likely to identify symptoms that are positive for concussions (P = 0.04). Both groups had difficulty recognizing subtle symptoms such as trouble sleeping, personality changes, and dizziness; they also were unaware that strenuous mental activities could delay concussion recovery, although ATCs scored significantly better than coaches (P < 0.001). Neither coaches nor ATCs consistently use standardized measures such as the Sports Concussion Assessment Tool 2 (7.5% vs 56.4%) or neuropsychological testing (5.3% vs 14.5%). CONCLUSIONS: This study describes coaches' and ATCs' varying knowledge and management techniques and highlights areas in which targeted interventions and outreach could be useful. These areas include increased ATC availability, coach/ATC concussion education, improved parent/athlete education, increased "return to think" awareness, and more consistent use of Sports Concussion Assessment Tool 2.

Children's injury database: development of an injury surveillance system in a pediatric emergency department.

BACKGROUND: Injuries are the leading cause of death in children and are also a leading cause of all emergency department (ED) visits for children. Obtaining epidemiologic data to define the wide range of childhood injuries for individual communities is challenging. The Children's Injury Database (CID) is an injury surveillance system developed to collect data from injury-related visits to our tertiary care pediatric emergency department. RESULTS: During 2021, a total of 15,168 injury visits were analyzed representing 22% of total ED visits (68,834). A total of 2053 injury visits (13.5%) resulted in hospital admission. The 10 leading injury types included: falls, poisonings, motor vehicle collision (MVC), assault, dog bite, burns, sports, pedestrian, bicycle, and all-terrain vehicle (ATV). Admission rates varied by age group with children ages 13 years and older having the highest rate of admission (18.4%). The median length of stay (LOS) for all injured children requiring admission was 2 days while the median LOS for preschoolers was 1 day, the median LOS for school-age children was 2 days, and the median LOS for teenagers was 3 days. While MVCs were the most common cause of vehicle-related injuries, ATV-related injuries had the highest rate of admission (51%). CONCLUSIONS: In this study, teenagers had significantly higher admission rates, lengths of stay, and hospital charges. Black and Hispanic children were under-represented in the number of visits for injuries compared to all ED visits. Further research should focus on disparities in injury-related visits based on race as well as gender. CID has demonstrated that injury surveillance systems can assist with reporting new injury patterns while also acting as a stimulus for new research ideas, planning interventions targeting the most at-risk populations, and evaluating the effectiveness of injury prevention interventions.

Paramedic King Laryngeal Tube airway insertion versus endotracheal intubation in simulated pediatric respiratory arrest.

INTRODUCTION: Pediatric endotracheal intubation (ETI) is difficult and can have serious adverse events when performed by paramedics in the prehospital setting. Paramedics may use the King Laryngeal Tube airway (KLT) in difficult adult airways, but only limited data describe their application in pediatric patients. OBJECTIVE: To compare paramedic airway insertion speed and complications between KLT and ETI in a simulated model of pediatric respiratory arrest. METHODS: This prospective, randomized trial included paramedics and senior paramedic students with limited prior KLT experience. We provided brief training on pediatric KLT insertion. Using a random allocation protocol, participants performed both ETI and KLT on a pediatric mannequin (6-month old size) in simulated respiratory arrest. The primary outcomes were 1) elapsed time to successful airway placement (seconds), and 2) proper airway positioning. We compared airway insertion performance between KLT and ETI using the Wilcoxon signed-ranks test. Subjects also indicated their preferred airway device. RESULTS: The 25 subjects included 19 paramedics and 6 senior paramedic students. Two subjects had prior adult KLT experience. Airway insertion time was not statistically different between the KLT (median 27 secs) and ETI (median 31 secs) (p = 0.08). Esophageal intubation occurred in 2 of 25 (8%) ETI. Airway leak occurred in 3 of 25 (12%) KLT, but ventilation remained satisfactory. Eighty-four percent of the subjects preferred the KLT over ETI. CONCLUSIONS: Paramedics and paramedic students demonstrated similar airway insertion performance between KLT and ETI in simulated, pediatric respiratory arrest. Most subjects preferred KLT. KLT may provide a viable alternative to ETI in prehospital pediatric airway management.

A new after-hours clinic model provides cost-saving, faster care compared with a pediatric emergency department.

OBJECTIVE: The objective of this study was to compare the charges and length of stay of demographically and clinically matched nonemergent patients managed in a new After-Hours Clinic (AHC) model versus a pediatric emergency department (PED). METHODS: Retrospective cross-sectional study conducted in a tertiary-care urban academic children's hospital. The AHC was off-site from the children's hospital emergency department. After-Hours Clinic patients were matched with PED patients for age, date and time of presentation, and chief complaint. The 95% confidence intervals for the difference in the means were used to compare the outcome variables of charges and length of stay. RESULTS: Of 471 patients seen at AHC in January 2008, 130 were matched to PED patients for date and time of presentation, age, and chief complaint, giving 260 study patients. There was no significant difference between AHC and PED patients in relationship to date and time of presentation, sex, age, and chief complaint. Comparing the length of stay and charges between AHC and PED patients revealed a significant difference in each. The patient-visit length-of-stay mean time for the AHC was 81.2 minutes less than the mean time for the PED (95.6 vs 176.8 minutes). The patient-visit mean charge for the AHC was $236.20 less than the mean charge for the PED ($226.00 vs $462.20). CONCLUSIONS: Our AHC model showed a significant reduction in length of stay and charges in compared demographically and clinically matched PED patients. This may be an effective model to help address emergency department overcrowding and promote patient safety.

Emergency department poisoning visits in children younger than 6 years: comparing referrals by a regional poison control center to referrals by other sources.

OBJECTIVE: The study purpose was to compare medical appropriateness and costs of regional poison control center (RPCC) versus non-RPCC referrals to children's hospital emergency department (ED) for acute poison exposure. METHODS: This is a retrospective cross-sectional study of children (<6 years) during an 8-month period, who presented for poison exposure. Demographic and clinical patient characteristics were abstracted onto a uniform data form. Medical appropriateness was determined by presence of 1 of 4 criteria by 3 independent reviewers blinded to the patients' race, source of referral, charges, and disposition. RESULTS: Determination of medical appropriateness was matched by all 3 reviewers in 187 patients who make up the study population. There were 92 RPCC-referred cases and 95 non-RPCC-referred controls. Groups were comparable by age, sex, toxin, and symptoms. For RPCC referrals, 84 were self-transported, and 8 were transported by emergency medical services. For non-RPCC referrals, 60 were self-referred/transported, 26 were transported by emergency medical services, and 9 were physician referred. Regional poison control center referrals had a 39.1% higher rate of medical appropriateness than did non-RPCC referrals (odds ratio, 13.0; 95% confidence interval, 3.6-36.1). For this sample, mean charges for inappropriate ED poison exposure visits were $313.42, and the cost per RPCC call was $25, thus giving a potential return on investment of 12.54 to 1 favoring RPCC triage. CONCLUSIONS: When compared with other referral sources, RPCC triage results in fewer unnecessary ED visits in this age group. Increasing prehospital use of poison centers would likely decrease unnecessary ED referrals and related costs.

Analysis of child passenger safety restraint use at a pediatric emergency department.

PURPOSE: The objectives of the study were to determine the number of children properly restrained during transit to a pediatric emergency department for care and to ascertain parental knowledge of Alabama laws and American Academy of Pediatrics (AAP) guidelines and where they obtain this information. METHODS: An emergency department (patient care rooms) waiting area, convenience sample of Alabama parents who have children younger than or 13 years of age were surveyed over a 5-week period. Appropriate use of child passenger safety (CPS) restraints was determined using Alabama law and AAP recommendations. Use of Car Seat Checks provided by Children's Hospital and Safe Kids, knowledge of Alabama laws and CPS guidelines, and the source of information used by parents were ascertained. RESULTS: Among 525 patients identified, 520 (99.0%) participated. Appropriate use per Alabama law and AAP guidelines was 72.3% and 60.6%, respectively; 5.0% were unrestrained. Booster seats were the most commonly misused restraint. Car seats were reportedly used correctly by 81.9%. Parents who had used the Car Seat Checks program had correct booster seat and car seat use rates of 95.8% and 61.5%, respectively. Unfortunately, only 31.2% of patients had knowledge of the Car Seat Checks program, and only 40.6% knew the current law. Most often, parents stated that the hospital where their child was born was the primary (and sometimes only) source of CPS information. CONCLUSIONS: This study illustrates the need for improving parental knowledge of appropriate child passenger restraint use (especially booster seats) and Car Seat Checks programs. Car seat program assistance is associated with high levels of appropriate use.

Factors associated with HIV viral load in a respondent driven sample in Los Angeles.

This study used a modified version of the Behavioral Model for Vulnerable Populations to examine the predisposing, enabling, and need factors associated with detectable viral load (VL). HIV status was measured using saliva and confirmed by blood. Of 797 persons enrolled, 193 were HIV positive and provided VL counts. A hierarchical multivariate logistic regression approach demonstrated that the predisposing factors of homelessness and recent substance abuse, particularly methamphetamine abuse, had a negative association with VL. The negative association of homelessness on VL was weakened with the introduction of enabling and need utilization factors. Mediation analysis indicated homelessness and HIV medication taking significantly associated with methamphetamine use as a predictor of detectable viral load. Guided policy to address substance abuse among those who are HIV positive is needed to improve biological outcomes.

Parental preferences for boarding locations when a children's hospital exceeds capacity.

STUDY OBJECTIVE: Our objective is to determine parental preferences for boarding locations when a children's hospital is at full capacity. We also assess parental interest in transfer to a general hospital when a children's hospital is experiencing crowding. METHODS: Eligible patients were surveyed within 24 hours of admission. Surveys were completed in emergency department (ED) and inpatient areas. Previous admission was not required; children with chronic illnesses were included. Parents were asked whether they would prefer their child to board in an ED hallway or inpatient hallway or whether they had no preference. Parents were also asked the maximum acceptable waiting time for an inpatient bed and whether they would prefer to be transferred to another hospital should the children's hospital not have a bed available. Responses were hypothetical and confidential and did not affect care. RESULTS: A total of 382 patients met enrollment criteria and 359 (94%) were enrolled; 58.8% (95% confidence interval [CI] 53.5% to 63.9%) preferred boarding on inpatient hallways, 11.1% (95% CI 8.2% to 15.0%) preferred ED hallways, and 30.1% (95% CI 25.4% to 35.2%) had no preference. Seventy percent (95% CI 65.2% to 74.9%) of parents preferred to wait at a children's hospital despite crowding. Most parents believed that the maximum acceptable waiting time was less than or equal to 3 hours. CONCLUSION: Parents of pediatric patients prefer boarding on inpatient hallways over ED hallways. The majority of parents prefer to remain at a children's hospital despite crowded conditions, but some parents may be amenable to transfer. These results may help institutions develop strategies to improve patient satisfaction when hospital capacity is exceeded.

Effectiveness of fever education in a pediatric emergency department.

OBJECTIVE: This study was designed to assess the impact of a brief educational video shown to parents during an emergency department visit for minor febrile illnesses. We hypothesized that a video about home management of fever would reduce medically unnecessary return emergency department visits for future febrile episodes. METHODS: A convenience sample of 280 caregivers presenting to one urban pediatric emergency department was enrolled in this prospective, randomized cohort study. All the caregivers presented with a child aged 3 to 36 months with complaint of fever and were independently triaged as nonemergent. A pretest and posttest were administered to assess baseline knowledge and attitudes about fever. One hundred forty subjects were randomized to view either an 11-minute video about home management of fever or a control video about child safety. Subjects were tracked prospectively, and all return visits for fever complaints were independently reviewed by 3 pediatric emergency physicians to determine medical necessity. RESULTS: There were no differences between the fever video and the control groups in baseline demographics (eg, demographically comparable). The fever video group had a significant improvement in several measures relating to knowledge and attitudes about childhood fever. There was no statistical difference between the intervention and control groups in subsequent return visits or in the determination of medical necessity. CONCLUSIONS: A brief standardized video about home management of fever improved caregiver knowledge of fever but did not decrease emergency department use or increase medical necessity for subsequent febrile episodes.

Sexual orientation and testing for prostate and colorectal cancers among men in California.

BACKGROUND: Previous quantitative studies have not compared the use of prostate and colorectal cancer (CRC) testing between gay/bisexual and heterosexual men. METHODS: We analyzed cross-sectional data on 19,410 men in the California Health Interview Survey. The percentage of respondents age 50 and over who received prostate and CRC tests was calculated across subgroups defined by self-reported sexual orientation, race/ethnicity, and a combined variable on sexual orientation and race/ethnicity. Multivariate regression analysis was used to identify variables on respondent characteristics that were independently associated with testing. RESULTS: In bivariate analyses, the percentage of gay/bisexual men receiving CRC tests was 6-10% greater than that of heterosexuals. There were no overall differences in prostate-specific antigen (PSA) test use between gay/bisexual and heterosexual men; however, use of these tests by gay/bisexual African Americans was 12-14% lower than that of heterosexual African Americans and 15-28% lower than that of gay/bisexual whites. In multivariate analyses, gay/bisexual men had greater odds of ever receiving CRC tests [odds ratio (OR) = 1.67; 95% confidence interval (CI) = 1.06-2.65], and lower odds of having an up-to-date PSA test than did heterosexuals (OR = 0.61; 95% CI = 0.42-0.89). However, interactions between sexual orientation and living situation showed that gay/bisexual men who lived alone had greater odds of receiving PSA tests than did other men (OR = 1.93; 95% CI = 1.23-3.03). CONCLUSIONS: Sexual orientation is independently associated with cancer testing among men. Future work should investigate the differences in this association by race/ethnicity and living situation.

Synthesis and solid-state structure of a Pt-Ru-P ternary metal phosphide (PtRuP2) as a carbon nanocomposite.

Reactive thermal degradation of Pt(PPh3)(Cl)(mu2-Cl)2Ru(Cl)(eta3:eta3-C10H16)/Vulcan carbon powder composites gives a nanocomposite powder containing nanocrystals of the expected PtRu alloy phase along with nanocrystals of an unknown substance. Yields of the unknown phase increase when PPh3 is added to the composite prior to thermal treatment. The new substance has been identified as a ternary metal phosphide, PtRuP2. Full-profile Rietveld analysis of the XRD pattern of this phase is consistent with a primitive Pm3m cubic unit cell (CsCl-type) having a cell constant of 2.78 A. Fully disordered Pt and Ru atoms occupy the (0, 0, 0) atomic positions with P atoms occupying interstitial sites at the (1/2, 1/2, 1/2) atomic positions.

Bicycle injury documentation before and after charting intervention.

BACKGROUND: Previous studies have shown that routinely completed free-text emergency department medical records contain limited information necessary for injury surveillance. We instituted an injury documentation sheet into our emergency department records to evaluate the impact on completeness of bicycle injury documentation rates. METHODS: The pretest/posttest study design used E-codes to identify bicycle-related injuries. A standardized data collection tool was utilized to review these charts. Time periods before (January 1 to December 31, 2004) and after (January 1 to June 30, 2005) institution of a standardized documentation sheet were reviewed. Data were entered into the computer program, Epistat, and scores were used for comparison. RESULTS: Initial review (n = 667) revealed mean age of patients 8.6 years, with 46% African American and 67% male. Helmet usage was documented in 49% of the charts (81 were wearing helmets; 245 were not wearing helmets). Mechanism of injury was documented as bicycle alone in 587, bicycle versus car in 13, and bicycle versus stationary object in 64. After implementation of an injury data sheet (n = 205), it was found that the mean age was 9.24 years, with 51% African American and 43% male. Helmet use was documented in 77% of cases (26 wearing helmets; 132 not wearing). Mechanism was documented as bicycle alone in 125, bicycle versus car in 66, and bicycle versus stationary object in 14. Helmet use was much more frequently documented after the initiation of an injury documentation reminder sheet (z = 6.97; P < 0.001; 95% confidence interval, 20.2-35.8). CONCLUSION: The use of standard injury documentation prompts increased completeness of documentation. With improved documentation, more accurate injury surveillance can be performed.

Black-White mortality from HIV in the United States before and after introduction of highly active antiretroviral therapy in 1996.

OBJECTIVES: We sought to describe Black-White differences in HIV disease mortality before and after the introduction of highly active antiretroviral treatment (HAART). METHODS: Black-White mortality from HIV is described for the nation as a whole. We performed regression analyses to predict county-level mortality for Black men aged 25-84 years and the corresponding Black:White male mortality ratios (disparities) in 140 counties with reliable Black mortality for 1999-2002. RESULTS: National Black-White disparities widened significantly after the introduction of HAART, especially among women and the elderly. In county regression analyses, contextual socioeconomic status (SES) was not a significant predictor of Black:White mortality rate ratio after we controlled for percentage of the population who were Black and percentage of the population who were Hispanic, and neither contextual SES nor race/ethnicity were significant predictors after we controlled for pre-HAART mortality. Contextual SES, race, and pre-HAART mortality were all significant and independent predictors of mortality among Black men. CONCLUSIONS: Although nearly all segments of the Black population experienced widened post-HAART disparities, disparities were not inevitable and tended to reflect pre-HAART levels. Public health policymakers should consider the hypothesis of unequal diffusion of the HAART innovation, with place effects rendering some communities more vulnerable than others to this potential problem.

Attitudes and perceptions of AIDS clinical trials group site coordinators on HIV clinical trial recruitment and retention: a descriptive study.

HIV-seropositive blacks, Hispanics, women of all ethnicities, and injection drug users (IDUs) have low rates of clinical trial participation. The opinions of research nurses and study coordinators as potential facilitators and barriers to access to clinical trials may contribute to this disparity. Study coordinators and research nurses from the adult AIDS Clinical Trials Group (ACTG) clinical trials units responded to an anonymous computer-based survey comprising multiple choice questions and clinical scenarios. Descriptive statistics were used to determine frequencies of responses. Recruitment rates of blacks, Hispanics, women and IDUs were mostly rated appropriate compared with the geographic region demographics. Most sites ranked white men as being the most interested in clinical trials. Sites rated their most effective interactions were with white men. Respondents felt they were less likely to enroll individuals who had missed previous clinical appointments or did not speak English. Perceptions that IDUs, Hispanics, blacks, and, to a lesser extent, women had less interest in clinical trials participation than white males may affect recruitment of the targeted populations. Interventions to improve interactions with targeted populations and to remove logistical and language barriers may improve the diversity of clinical trial participants.

Accuracy of weight estimation methods for children.

OBJECTIVES: To evaluate differences in accuracy of 2 weight estimation methods for children when compared with measured weights: the Broselow-Luten tape (patient's height as the predictor) and the devised weight estimation method (DWEM) (patient's height and body habitus as predictors). METHODS: Information was obtained prospectively on a convenience sample of patients presenting through triage on nonconsecutive days at the Children's Hospital Emergency Department. Weight was measured in kilograms, and a measured length or height in centimeters was obtained, as well as 2 independent assessments of body habitus. Weights were then estimated using the Broselow-Luten tape and the DWEM. This study evaluated 4 separate weight classes: less than or equal to 10 kg, 10.1 to 20 kg, 20.1 to 36 kg, and 36.1 kg or more. One hundred children were recruited into each weight class, for a total of 400 children. Comparisons of estimations with measured weights were made using the Pearson correlation coefficient method. Mean percentage errors were calculated for weight estimations by both methods. RESULTS: Both the Broselow-Luten and DWEM weight estimations when compared with measured weights showed statistical correlation (using the Pearson correlation coefficient). However, the Broselow-Luten method had a negative mean percentage error in all weight classes, and the DWEM had a negative mean percentage error in classes greater than 20 kg, indicating an underestimation of weight in those classes. CONCLUSIONS: Although both the Broselow-Luten and DWEM weight estimations show statistical correlation with measured weights, the Broselow-Luten method underestimates weights in all weight classes, and the DWEM underestimates weights in the weight classes greater than 20 kg.

Pediatric Residents' Perceptions of Potential Professionalism Violations on Social Media: A US National Survey.

BACKGROUND: The ubiquitous use of social media by physicians poses professionalism challenges. Regulatory bodies have disseminated guidelines related to physicians' use of social media. OBJECTIVE: This study had 2 objectives: (1) to understand what pediatric residents view as appropriate social media postings, and (2) to recognize the degree to which these residents are exposed to postings that violate social media professionalism guidelines. METHODS: We distributed an electronic survey to pediatric residents across the United States. The survey consisted of 5 postings from a hypothetical resident's personal Facebook page. The vignettes highlighted common scenarios that challenge published social media professionalism guidelines. We asked 2 questions for each vignette regarding (1) the resident's opinion of the posting's appropriateness, and (2) their frequency of viewing similar posts. We also elicited demographic data (age, sex, postgraduate year level), frequency of Facebook use, awareness of their institutional policies, and prior social media training. RESULTS: Of 1628 respondents, 1498 (92.01%) of the pediatric residents acknowledged having a Facebook account, of whom 888/1628 (54.55%) reported daily use and 346/1628 (21.25%) reported using Facebook a few times a week. Residents frequently viewed posts that violated professionalism standards, including use of derogatory remarks about patients (1756/3256, 53.93%) and, much less frequently, about attending physicians (114/1628, 7.00%). The majority of the residents properly identified these postings as inappropriate. Residents had frequently viewed a post similar to one showing physicians drinking alcoholic beverages while in professional attire or scrubs and were neutral on this post's appropriateness. Residents also reported a lack of knowledge about institutional policies on social media (651/1628, or 40.00%, were unaware of a policy; 204/1628, or 12.53%, said that no policy existed). A total of 372/1628 respondents (22.85%) stated that they had never received any structured training on social media professionalism. CONCLUSIONS: Today's residents, like others of their generation, use social media sites to converse with peers without considering the implications for the profession. The frequent use of social media by learners needs to change the emphasis educators and regulatory bodies place on social media guidelines and teaching professionalism in the digital age.

Brief report: Influenza vaccination and health care workers in the United States.

OBJECTIVE: To determine influenza vaccination rates among U.S. health care workers (HCWs) by demographic and occupational categories. DESIGN AND PARTICIPANTS: We analyzed data from the 2000 National Health Interview Survey (NHIS). Weighted multivariable analyses were used to evaluate the association between HCW occupation and other variables potentially related to receipt of influenza vaccination. HCWs were categorized based on standard occupational classifications as health-diagnosing professions, health-assessing professions, health aides, health technicians; or health administrators. MAIN INDEPENDENT VARIABLES: Demographic characteristics and occupation category. MAIN OUTCOME VARIABLES: Receipt of influenza vaccination within 12 months of survey. ANALYSIS: Descriptive statistics and weighted multivariable logistic regression. RESULTS: There were 1,651 HCWs in the final sample. The overall influenza vaccination rate for HCWs was 38%. After weighted multivariable analyses, HCWs who were under 50 (odds ratio [OR] 0.67%, 95% confidence interval [CI]: 0.50 to 0.89, compared with HCWs 50 to 64), black (OR 0.57 95% CI: 0.42, 0.78, compared with white HCWs), or were health aides (OR 0.73%, 95% CI: 0.51, 1.04, compared with health care administrators and administrative support staff) had lower odds of having been vaccinated against influenza. CONCLUSIONS: The overall influenza vaccination rate among HCWs in the United States is low. Workers who are under 50, black, or health aides have the lowest rates of vaccinations. Interventions seeking to improve HCW vaccination rates may need to target these specific subgroups.

Interventions to increase children's booster seat use: a review.

BACKGROUND: In children aged 4 to 8 years, booster seats are estimated to reduce by 59% the odds of sustaining clinically significant injuries during a motor vehicle crash, compared to using ordinary vehicle seat belts. Given the safety benefits of booster seats, public health and traffic safety agencies recommend their use for children aged 4 to 8 years traveling in motor vehicles, until the vehicle seat belt can fit them properly. Despite these benefits, booster seat use remains low. Interventions aimed at promoting the use of booster seats for children aged 4 to 8 years have been implemented, but there is little evidence regarding their effects. METHODS: The Cochrane methodology was used to assess the effects of interventions to increase booster seat use for children aged 4 to 8 years. The reviewers searched online databases, scanned reference lists, hand-searched journals, and contacted relevant agencies and researchers for both randomized controlled trials and controlled before-and-after evaluation studies. The search concluded in 2005 and was not restricted by publication status or language. RESULTS: The search yielded 1350 potential studies. Of these, five studies involving 3070 individuals met the inclusion criteria. Interventions were generally effective in increasing booster seat use among children aged 4 to 8 years. Education paired with incentive or distribution programs produced more consistent results than education-only interventions that targeted parents, children, or both. CONCLUSIONS: Incentives or the distribution of free booster seats combined with education increase the use of booster seats.
