Telemedicine Quality Improvement during the Corona Virus 2019 Pandemic Increases Pediatric Weight Management Access

Background

The corona virus 2019 pandemic disrupted care for pediatric patients with chronic conditions, including those with childhood obesity. Lockdowns forced providers to create new ways of caring for this population. Telemedicine was a promising but previously unavailable solution. This quality improvement report details how the Healthy and Fit Children's Clinic transitioned and improved care via telemedicine.

Methods

Between March 2020 and April 2021, the quality improvement project team incorporated the Model for Improvement to transition the clinic to telemedicine. The team tracked Healthy and Fit Children's Clinic appointments, no-shows, billing and reimbursement data, and noted unintended consequences or unanticipated barriers. Patients and their families were given a satisfaction survey at the end of each telemedicine encounter.

Results

Compared with pre-telemedicine implementation, there was a 120% increase in completed patient clinic visits per week and a sustained positive shift above the established baseline. Telemedicine no-show rates achieved <10%, with an average sustained rate of <20%, compared with unchanged in-person no-show rates of >50% pre- and post-telemedicine implementation. There was a 74% increase in monthly billing and a sustained positive shift above the pre-telemedicine baseline. On average, patients rated all six satisfaction questions ≥92 on the 100-point scale (compared with 83 pre-telemedicine).

Conclusions

This transition to telemedicine was successful and could be translatable to other clinic sites. Patients attended their clinic visits more consistently and were highly satisfied with their care. In a population where continuity of care is paramount, telemedicine shows promise as a tool to treat childhood obesity.

Evaluating a web-based training curriculum for disseminating best practices for the care of newborns with neonatal opioid withdrawal syndrome in a rural hospital, the NOWS-NM Program

BACKGROUND

The incidence of neonatal opiate withdrawal syndrome (NOWS) in the US has grown dramatically over the past two decades. Many rural hospitals not equipped to manage these patients transfer them to hospitals in bigger cities.

METHODS

We created a curriculum, the NOWS-NM Program, a web-based curriculum training in best practices. To evaluate the curriculum, we conducted pre- and post-surveys of NOWS knowledge, attitudes, and care practices, plus post-curriculum interviews and focus groups.

RESULTS

Fourteen participants completed both pre- and post-curriculum surveys. They indicated an increase in knowledge and care practices. A small number of respondents expressed negative attitudes about parents of infants with NOWS at pre-test, the training curriculum appeared to have no impact on such attitudes at post-test. Sixteen participants participated in focus groups or interviews. Qualitative data reinforced the positive quantitative results and contradicted the negative survey results, respondents reported that the program did reduce stigma and improve provider/staff interactions with patients.

CONCLUSIONS

This curriculum demonstrated positive impacts on NOWS knowledge and care practices. Incorporating focus on core concepts of trauma-informed care and self-regulation in future iterations of the curriculum may strengthen the opportunity to change attitudes and address the needs expressed by participants and improve care of families and babies with NOWS.

High Prevalence of Elevated Alanine Aminotransferase in American Indian Children Seen in a Pediatric Weight Management Clinic

INTRODUCTION

Elevated alanine aminotransferase (ALT) can indicate risk of metabolic dysfunction-associated steatotic liver disease. However, there is little data about the prevalence of elevated ALT in American Indian (AI) children.

METHODS

Baseline data from children attending the pediatric weight management clinic were used to describe the prevalence of elevated ALT, stratified by race and ethnicity.

RESULTS

The prevalence of elevated ALT was higher among children who were male, were older, had higher body mass index Z scores, and were non-Hispanic and AI.

DISCUSSION

In this clinic, AI children with overweight and obesity had a disproportionately high prevalence of elevated ALT; root causes of this disparity should be identified.

Evaluating a Web-based Training Curriculum for Disseminating Best Practices for the Care of Newborns with Neonatal Opioid Withdrawal Syndrome in a Rural Hospital, the NOWS-NM Program

Background

The incidence of neonatal opiate withdrawal syndrome (NOWS) in the US has grown dramatically over the past two decades. Many rural hospitals not equipped to manage these patients transfer them to hospitals in bigger cities.

Methods

We created a curriculum, the NOWS-NM Program, a mobile/web-based curriculum training in best practices. To evaluate the curriculum, we conducted pre- and post-surveys of NOWS knowledge, attitudes, and care practices, plus post-curriculum interviews and focus groups.

Results

Fourteen participants completed both pre- and post-curriculum surveys. They indicated an increase in knowledge and care practices. A small number of respondents expressed negative attitudes about parents of infants with NOWS at pre-test, the training curriculum appeared to have no impact on such attitudes at post-test. Sixteen participants participated in focus groups or interviews. Qualitative data reinforced the positive quantitative results and contradicted the negative survey results, respondents reported that the program did reduce stigma and improve provider/staff interactions with patients.

Conclusions

This curriculum demonstrated positive impacts on NOWS knowledge and care practices. Incorporating focus on core concepts of trauma-informed care and self-regulation in future iterations of the curriculum may strengthen the opportunity to change attitudes and address the needs expressed by participants and improve care of families and babies with NOWS.

Significance

This project evaluates a novel curriculum covering best practices in care of infants with neonatal opiate withdrawal syndrome (NOWS) and is oriented toward supporting care in rural NM hospitals. We evaluated the curriculum with both quantitative and qualitative methods. Results support the effectiveness of the curriculum to increase competence of rural providers in the care of patients with NOWS. The NOWS-NM Program is a novel and effective mobile training tool, especially for under-resourced, rural hospitals.

Teen and caregiver perspectives on success, clinician role, and family involvement in ACTION PAC, a weight management intervention trial

OBJECTIVE

Describe perspectives of teens and caregivers regarding motivations, successes, and challenges related to participation in ACTION PAC (ClinicalTrials.gov: NCT02502383), a two-year weight management trial.

METHODS

Intervention group participants received 16 short motivational interviewing (MI) sessions with school-based health center (SBHC) primary care clinicians over two years. Post-study, we conducted semi-structured interviews with purposefully sampled intervention group teens and their caregivers. Interviews were audio recorded, transcribed, and managed in NVivo 11. Three independent coders analyzed the data, developed a coding tree, examined how codes intersected and clarified relationships through memo writing.

RESULTS

The clinician's role and use of motivational interviewing and family involvement in behavior changes were cited as critical to success. Some adolescents noted difficulty in sustaining behavior changes post-intervention and social and systemic barriers to behavior change.

CONCLUSION

Future studies should identify strategies to sustain teen motivation, better involve families, and address systemic barriers.

INNOVATION

In this study, which simulated real-world SBHC conditions, adolescents appreciated the use of an MI approach and felt that was key to their success, indicating the potential to continue use of this approach to motivating behavior changes in SBHC settings.

Virtual Intrauterine Device Placement Training Improves Clinician Comfort

Background and Objectives: Virtual intrauterine device (IUD) training options can improve clinician continuing education and patient IUD access. Our objective was to evaluate a virtual, hands-on IUD training for primary care clinicians. Methods: Training sessions occurred via video conferencing and included didactic instruction on IUD eligibility, counseling, placement, and removal. Trainers used pelvic models to demonstrate procedures for all Food and Drug Administration-approved IUDs and guided trainees during hands-on practice with IUDs. Surveys administered before and immediately after training assessed clinician satisfaction and evaluated pre-to-posttraining changes in self-rated comfort level with IUD procedures. We evaluated the changes using Wilcoxon signed-rank sum tests. Results: Thirty-four New Mexico clinicians were trained during 29 sessions from January-June 2021. Trainees (n=32 responding to pre/postsurveys) included nurse practitioners and midwives (48%), physician assistants (28%), physicians (17%), and clinicians in training (7%). Approximately one-third (37%) had previous experience placing IUDs. Elements of training delivery were highly rated by clinicians, with all trainees successfully using the virtual platform and half indicating that they would potentially choose a virtual training over an in-person option in the future. After the training, clinicians reported significantly increased comfort with all aspects of IUD placement and removal (P≤.01). Conclusions: An interactive, virtual IUD training model was highly rated among practicing clinicians and increased their comfort with IUD placement and removal.

Individual differences in the effects of the ACTION-PAC intervention: an application of personalized medicine in the prevention and treatment of obesity

There is an increased interest in the use of personalized medicine approaches in the prevention or treatment of obesity, however, few studies have used these approaches to identify individual differences in treatment effects. The current study demonstrates the use of the predicted individual treatment effects framework to test for individual differences in the effects of the ACTION-PAC intervention, which targeted the treatment and prevention of obesity in a high school setting. We show how methods for personalized medicine can be used to test for significant individual differences in responses to an intervention and we discuss the potential and limitations of these methods. In our example, 25% of students in the preventive intervention, were predicted to have their BMI z-score reduced by 0.39 or greater, while at other end of the spectrum, 25% were predicted to have their BMI z-score increased by 0.09 or more. In this paper, we demonstrate and discuss the process of using methods for personalized medicine with interventions targeting adiposity and discuss the lessons learned from this application. Ultimately, these methods have the potential to be useful for clinicians and clients in choosing between treatment options, however they are limited in their ability to help researchers understand the mechanisms underlying these predictions.

Facilitators and Barriers to Pediatric Clinical Trial Recruitment and Retention in Rural and Community Settings: A Scoping Review of the Literature

Children in rural settings are underrepresented in clinical trials, potentially contributing to rural health disparities. We performed a scoping review describing available literature on barriers and facilitators impacting participation in pediatric clinical trials in rural and community-based (non-clinical) settings. Articles identified via PubMed, CINAHL, Embase, and Web of Science were independently double-screened at title/abstract and full-text levels to identify articles meeting eligibility criteria. Included articles reported on recruitment or retention activities for U.S.-based pediatric clinical studies conducted in rural or community-based settings and were published in English through January 2021. Twenty-seven articles describing 31 studies met inclusion criteria. Most articles reported on at least one study conducted in an urban or suburban or unspecified community setting (n=23 articles; 85%); fewer (n=10; 37%) reported on studies that spanned urban and rural settings or were set in rural areas. More studies discussed recruitment facilitators (n=25 studies; 81%) and barriers (n=19; 61%) versus retention facilitators (n=15; 48%) and barriers (n=8; 26%). Descriptions of recruitment and retention barriers and facilitators were primarily experiential or subjective. Recruitment and retention facilitators were similar across settings and included: contacts/reminders, community engagement and relationship-building, consideration of participant logistics, and incentives. Inadequate staff and resources were commonly cited recruitment and retention barriers. Few studies have rigorously examined optimal ways to recruit and retain rural participants in pediatric clinical trials. To expand the evidence base, future studies examining recruitment and retention strategies should systematically assess and report rurality and objectively compare relative impact of different strategies.

Capacity Building for a New Multicenter Network Within the ECHO IDeA States Pediatric Clinical Trials Network

Introduction: Research capacity building is a critical component of professional development for pediatrician scientists, yet this process has been elusive in the literature. The ECHO IDeA States Pediatric Clinical Trials Network (ISPCTN) seeks to implement pediatric trials across medically underserved and rural populations. A key component of achieving this objective is building pediatric research capacity, including enhancement of infrastructure and faculty development. This article presents findings from a site assessment inventory completed during the initial year of the ISPCTN. Methods: An assessment inventory was developed for surveying ISPCTN sites. The inventory captured site-level activities designed to increase clinical trial research capacity for pediatrician scientists and team members. The inventory findings were utilized by the ISPCTN Data Coordinating and Operations Center to construct training modules covering 3 broad domains: Faculty/coordinator development; Infrastructure; Trials/Research concept development. Results: Key lessons learned reveal substantial participation in the training modules, the importance of an inventory to guide the development of trainings, and recognizing local barriers to clinical trials research. Conclusions: Research networks that seek to implement successfully completed trials need to build capacity across and within the sites engaged. Our findings indicate that building research capacity is a multi-faceted endeavor, but likely necessary for sustainability of a unique network addressing high impact pediatric health problems. The ISPCTN emphasis on building and enhancing site capacity, including pediatrician scientists and team members, is critical to successful trial implementation/completion and the production of findings that enhance the lives of children and families.

Formative Evaluation for Implementation of a Low Literacy Pictorial Asthma Action Plan Delivered via Telehealth Improves Asthma Control

Consistently uncontrolled asthma in children is an increasing concern in the United States. The use of asthma action plans with asthma education is inconsistent and may be improved with adaptations for low literacy. The objective of this study was formative evaluation for implementation of the New Mexico Pictorial Asthma Action Plan (NM PicAAP). Quality improvement processes guided NM PicAAP face validation and telehealth direct patient care implementation. The asthma control test was selected to measure asthma control. NM PicAAP was revised for face validity, and training curriculum on its use and telehealth implementation processes were developed. Seven youth received NM PicAAP via telehealth direct care, which increased overall asthma control scores over 1 month. NM PicAAP may be useful and effective for improving asthma care in children via telehealth. Additional testing is needed to assess applicability.

Rural-Urban Differences in Baseline Dietary Intake and Physical Activity Levels of Adolescents

INTRODUCTION

Differences in dietary intake and physical activity may explain the higher prevalence of obesity among adolescents living in rural versus urban settings. The objective of this cross-sectional secondary analysis was to compare baseline dietary intake and physical activity of adolescents by rurality.

METHODS

We analyzed data on 940 adolescents who participated in ACTION PAC (Adolescents Committed to Improvement of Nutrition and Physical Activity), an obesity prevention and management intervention trial conducted from 2014 through 2017 in 8 public high schools in the southwestern United States. Dietary intake was assessed with the Block Food Screener, and participants completed an exercise log and wore an accelerometer to provide data on physical activity. We compared data by rural-urban commuting area (RUCA) codes and log population density by using multilevel models, with students nested within zip code and repeated measures for accelerometer analysis.

RESULTS

After adjusting for socioeconomic status and ethnicity, accelerometer data indicated that moderate-to-vigorous physical activity was 8.17 min/d (P = .02) higher and sedentary time was 20.42 min/d (P = .02) lower in moderately urban areas than in the urban reference area. Each 1-unit increase in log population density was associated with higher reported intake of whole grains (0.02 ounce equivalents, P = .03), potatoes (0.01 cup equivalents, P = .02), and added sugar (0.37 tsp, P = .02) after adjusting for socioeconomic status and ethnicity.

CONCLUSION

Differences in reported dietary intake and physical activity level by measures of rurality were small and inconsistent in direction to explain the disparities observed in rural versus urban areas.

Motivational Interviewing to Treat Adolescents With Obesity: A Meta-analysis

CONTEXT

Successful treatment approaches are needed for obesity in adolescents. Motivational interviewing (MI), a counseling approach designed to enhance behavior change, shows promise in promoting healthy lifestyle changes.

OBJECTIVE

Conduct a systematic review of MI for treating overweight and obesity in adolescents and meta-analysis of its effects on anthropometric and cardiometabolic outcomes.

DATA SOURCES

We searched Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, PsychINFO, Web of Science, Cochrane Library, and Google Scholar from January 1997 to April 2018.

STUDY SELECTION

Four authors reviewed titles, abstracts, and full-text articles.

DATA EXTRACTION

Two authors abstracted data and assessed risk of bias and quality of evidence.

RESULTS

Seventeen studies met inclusion criteria; 11 were included in the meta-analysis. There were nonsignificant effects on reducing BMI (mean difference [MD] -0.27; 95% confidence interval -0.98 to 0.44) and BMI percentile (MD -1.07; confidence interval -3.63 to 1.48) and no discernable effects on BMI z score, waist circumference, glucose, triglycerides, cholesterol, or fasting insulin. Optimal information size necessary for detecting statistically significant MDs was not met for any outcome. Qualitative synthesis suggests MI may improve health-related behaviors, especially when added to complementary interventions.

LIMITATIONS

Small sample sizes, overall moderate risk of bias, and short follow-up periods.

CONCLUSIONS

MI alone does not seem effective for treating overweight and obesity in adolescents, but sample size and study dose, delivery, and duration issues complicate interpretation of the results. Larger, longer duration studies may be needed to properly assess MI for weight management in adolescents.

Overweight adolescents' brain response to sweetened beverages mirrors addiction pathways

Many adolescents struggle with overweight/obesity, which exponentially increases in the transition to adulthood. Overweight/obesity places youth at risk for serious health conditions, including type 2 diabetes. In adults, neural substrates implicated in addiction (e.g., orbitofrontal cortex (OFC), striatum, amygdala, and ventral tegmental area) have been found to be relevant to risk for overweight/obesity. In this study, we examined three hypotheses to disentangle the potential overlap between addiction and overweight/obesity processing by examining (1) brain response to high vs. low calorie beverages, (2) the strength of correspondence between biometrics, including body mass index (BMI) and insulin resistance, and brain response and (3) the relationship between a measure of food addiction and brain response using an established fMRI gustatory cue exposure task with a sample of overweight/obese youth (M age = 16.46; M BMI = 33.1). Greater BOLD response was observed across the OFC, inferior frontal gyrus (IFG), nucleus accumbens, right amygdala, and additional frontoparietal and temporal regions in neural processing of high vs. low calorie beverages. Further, BMI scores positively correlated with BOLD activation in the high calorie > low calorie contrast in the right postcentral gyrus and central operculum. Insulin resistance positively correlated with BOLD activation across the bilateral middle/superior temporal gyrus, left OFC, and superior parietal lobe. No relationships were observed between measures of food addiction and brain response. These findings support the activation of parallel addiction-related neural pathways in adolescents' high calorie processing, while also suggesting the importance of refining conceptual and neurocognitive models to fit this developmental period.

Effect of Including Alcohol and Cannabis Content in a Sexual Risk-Reduction Intervention on the Incidence of Sexually Transmitted Infections in Adolescents: A Cluster Randomized Clinical Trial

Importance

Adolescents in the juvenile justice system are at high risk for sexually transmitted infections (STIs). Concurrent use of alcohol and cannabis increase this risk.

Objective

To determine whether a theory-based sexual risk-reduction intervention that included alcohol- and cannabis-focused content resulted in greater reductions in STIs than an intervention that included alcohol-related content only and an intervention that did not include substance use content.

Design, Setting, and Participants

Cluster randomized clinical trial with 3 conditions. Between July 1, 2010, and December 10, 2014, adolescents living at a juvenile detention facility in the southwestern United States were tested and treated for STI before randomization and again 12 months after the intervention. Data analyses were conducted in July and August 2017. Eligibility criteria included (1) being aged 14 to 18 years, (2) able to speak English, (3) having a remaining detention term of less than 1 month, and (4) signing a release granting access to STI results if tested at intake. Six hundred ninety-three adolescents were assessed for eligibility. Of these, 460 completed baseline assessments and were randomized to 1 of 3 intervention conditions. Data analysis was by intent-to-treat.

Interventions

There were 3 intervention conditions: sexual risk reduction intervention (SRRI); SRRI plus alcohol content (SRRI + ETOH); and SRRI + ETOH plus cannabis content (SRRI + ETOH + THC). Interventions were conducted in same-sex groups by trained clinicians and included video presentations with discussion, group activities, and active feedback by participants, consistent with the principles of motivational enhancement therapy.

Main Outcomes and Measures

Although not the outcome on which the study was originally powered, the main outcome variable presented herein is STI incidence (Chlamydia trachomatis and/or Neisseria gonorrhoeae) 12 months after the intervention.

Results

Of the 460 participants randomized, mean (SD) age was 15.8 (1.1) years, 347 participants (75.4%) were male, and 57.0% were of Hispanic ethnicity. Among the participants, 143 were randomized to SSRI, 155 to SRRI + ETOH, and 162 to SRRI + ETOH + THC. Attrition at 12-month follow-up was 99 (21.5%) for the STI outcome variable. Participants in the SRRI + ETOH + THC intervention had lower incidence of STI at follow-up (3.9%) than those in either the SRRI (12.4%; odds ratio, 0.29; 95% CI, 0.10-0.84) or the SRRI + ETOH (10.2%; odds ratio, 0.36; 95% CI, 0.12-1.05) interventions.

Conclusions and Relevance

An intervention delivered in a motivational enhancement therapy format that includes theory-based sexual risk reduction combined with alcohol- and cannabis-focused elements is effective at reducing STI incidence among justice-involved adolescents. This 1-session manualized intervention can be delivered in the context of short-term detention and is easily disseminated to juvenile justice agencies.

Risky Sex in High-Risk Adolescents: Associations with Alcohol Use, Marijuana Use, and Co-Occurring Use

Risky sexual behavior and substance use appear to be interconnected behaviors among adolescents, but data are scarce regarding the extent to which sexual risk behavior is associated with high levels of marijuana and alcohol use, both separately and in combination. 301 adolescents were recruited from a short-term detention facility, and substance use and risky sexual behavior were assessed. We found that adolescents who frequently used marijuana, but not alcohol, reported significantly less risky sex as well as greater intentions to use condoms than either adolescents who frequently used alcohol, but not marijuana, or adolescents who frequently used both substances. Substance use status as a predictor of future risky sexual behavior followed a similar pattern. When designing interventions to reduce substance use in the context of risky sex, it might be especially effective to target efforts toward reducing harm associated with alcohol use, either alone or in combination with marijuana use.

Training Primary Care Providers in the Use of Motivational Interviewing for Youth Behavior Change

BACKGROUND AND PURPOSE

Adolescent obesity is a global epidemic. Motivational interviewing (MI) is a promising strategy to address adolescent obesity risk behaviors. However, primary care providers (PCPs) tend to express discomfort with learning and adopting MI practices and with addressing patient weight issues. PCP proficiency in using MI to discuss body mass index, health screening results, and nutrition and physical activity behaviors after receiving training and coaching from an MI expert and practicing the technique was evaluated. We hypothesized that comfort with MI would increase consistently over time.

METHODS

Self-assessment surveys in MI proficiency were administered to PCPs after every youth participant MI session. MI comfort as determined by proficiency was categorized into low, medium, and high comfort according to survey Likert scale responses. Data were analyzed using analysis of variance (ANOVA) and Fisher's exact tests.

RESULTS

Two hundred twenty-seven youth were seen for MI-based discussions by 4 PCPs. Two hundred twenty-six surveys had complete data for analysis. As anticipated, overall PCPs reported significantly more comfort with MI from the first to the final MI session over a 2- to 3-month period (p< .001). Comfort scores did not increase linearly over time for all PCPs. Despite standard training practices, overall MI proficiency as measured by comfort scores varied by PCP (p< .01).

IMPLICATIONS FOR PRACTICE

This type of MI training program should be considered for clinical nurses and nurse practitioners during their nursing education training to facilitate their ability to consistently and effectively support youth behavior change for conditions such as obesity (ClinicalTrials.gov Number NCT02502383).

Association between circulating CCL2 levels and modifiable behaviors in overweight and obese adolescents: a cross-sectional pilot study

BACKGROUND

We evaluated the relationship between an early inflammatory biomarker, chemokine (C-C motif) ligand 2 (CCL2), and other clinical biomarkers and lifestyle behaviors, in overweight/obese adolescents at high risk of developing cardiometabolic derangements.

METHODS

We collected anthropometric measurements, clinical biomarkers, and three 24-h dietary recalls from 21 vocational high school students (91% male), 14-19 years, with body mass index (BMI) ≥25 kg/m2. Pearson's or Spearman's correlation coefficients were used to examine relationships.

RESULTS

Mean BMI was 33.2 kg/m2 (range 25.7-45.6) and 38% were prediabetic by fasting glucose. Mean CCL2 was 512.9 pg/mL (range 220-917) and positively correlated with triglycerides (r=0.45; p=0.04) and TNF-α (r=0.57; p=0.007) and marginally negatively correlated with fruit/vegetable intake (r=-0.42, p=0.06) and omega-3 fatty acids (r=-0.41, p=0.07).

CONCLUSIONS

CCL2 was positively associated with pro-inflammatory biomarkers and negatively associated with some anti-inflammatory dietary factors.

Usability Testing of an HPV Information Website for Parents and Adolescents

OBJECTIVE

Parents make the decisions regarding their children's health care. Unfortunately, many parents are misinformed about HPV and HPV vaccines. In order to help parents make an informed decision regarding HPV vaccination for their daughter, the GoHealthyGirls website was created for parents and their adolescent daughters. Usability testing was conducted with members of the target population to refine the website prior to conducting an efficacy trial.

METHODS

Parents with girls (n=9) between the ages of 11-13 and 11-13 year old adolescents (n=10) were recruited for usability testing. The testing consisted of completing twelve scenarios where participants were asked to find specific information on the GoHealthyGirls site. This was followed by a self-administered system usability scale-to determine ease of use and functionality of the website-and a user satisfaction survey.

RESULTS

Both adult and adolescent participants were able to easily find the requested information and reported an increased positive opinion of HPV vaccines after visiting the website. Both groups of participants reported favorable evaluations of using the website.

CONCLUSION

The GoHealthyGirls website has the potential to help parents of adolescent daughters make an informed decision about HPV vaccination. A large scale efficacy trial will determine its usefulness.

Investigating stakeholder attitudes and opinions on school-based human papillomavirus vaccination programs

BACKGROUND

In several countries worldwide, school-based human papillomavirus (HPV) vaccination programs have been successful; however, little research has explored US stakeholders' acceptance toward school-based HPV vaccination programs.

METHODS

A total of 13 focus groups and 12 key informant interviews (N = 117; 85% females; 66% racial/ethnic minority) were conducted with 5 groups of stakeholders: parents of adolescent girls, parents of adolescent boys, adolescent girls, middle school nurses, and middle school administrators throughout the 5 public health regions of New Mexico.

RESULTS

All groups of stakeholders lacked knowledge on HPV and HPV vaccines. Stakeholders were interested in--but apprehensive about--the benefits of HPV vaccination. Despite previous literature showing the benefits of using middle schools as an HPV vaccination site, stakeholders did not deem middle schools as a viable site for vaccination. Nurses reported that using the school as an HPV vaccination site had not occurred to them; parents and adolescents stated they were uncertain about using this type of program. School administrators indicated that they lacked implementation authority.

CONCLUSIONS

Our study uncovered barriers to using middle schools as a site of HPV vaccination. Resources should be directed toward increased support and education for middle school nurses who function as opinion leaders relevant to the uptake of HPV vaccination.

Beta-test Results for an HPV Information Web site: GoHealthyGirls.org - Increasing HPV Vaccine Uptake in the United States

A web site, GoHealthyGirls, was developed to educate and inform parents and their adolescent daughters about human papillomavirus (HPV) and HPV vaccines. This article provides an overview of web site development and content followed by the results of a beta-test of the web site. 63 New Mexican parents of adolescent girls tested the site. Results indicated that GoHealthyGirls was a functioning and appealing web site. During this brief educational intervention, findings suggest that the web site has the potential to increase HPV vaccine uptake. This research supports the Internet as a valuable channel to disseminate health education and information to diverse populations.

Different models of HPV vaccine decision-making among adolescent girls, parents, and health-care clinicians in New Mexico

OBJECTIVE

Human papillomavirus (HPV) vaccination rates in the United States have been lower than anticipated since the vaccine became widely available globally in 2006. Of particular concern are data that suggest disparities in vaccine receipt among US ethnic minority and health disparity populations such as Hispanics, who are disproportionately affected by cervical cancer. Given these trends, it is important to examine actual vaccination decision-making processes among clinicians, parents, and adolescents to identify strategies to enhance uptake.

DESIGN

We conducted a mixed-method study examining HPV vaccine decision-making, utilizing both structured questionnaires of primarily Hispanic mothers and daughters (aged 12-18) and semi-structured interviews with mothers, daughters, and health-care clinicians to more deeply investigate decision-making dynamics. Quantitative analysis was used for descriptive purposes, while qualitative analysis featured an iterative process to examine factors related to decision-making surrounding the HPV vaccine. The study was conducted in two primary care clinics serving predominantly Hispanic patients in an urban New Mexico setting through Research Involving Outpatient Setting Network (RIOS Net), a primary care practice-based research network.

RESULTS

We administered 22 questionnaires and conducted 30 interviews. We identified three aspects of vaccine delivery that were similar across clinics: availability/supply of the vaccine, favorable clinician attitudes toward the vaccine, and clinicians' competing demands. We also identified three decision-making stages (pre-encounter, encounter, and post-encounter), though we found distinct differences in decision-making processes at the two sites. We describe the differences between an encounter-based and a process-based model of decision-making, and the ways in which explanatory factors might influence the decision-making process.

CONCLUSION

Our findings suggest that factors other than race and ethnicity, such as education, socioeconomic status, and health-care access, play an important role in HPV vaccination decisions. Further research to elucidate the specific informational needs and communication strategies associated with these factors will be needed to enhance vaccine uptake.

An adaptive CBPR approach to create weight management materials for a school-based health center intervention

PURPOSE

From our previous clinical work with overweight/obese youth, we identified the need for research to create an effective weight management intervention to address the growing prevalence of adolescent metabolic syndrome. Formative assessment through an adaptive community-based participatory research (CBPR) approach was conducted toward the development of a nutritional and physical activity (DVD) and clinician toolkit for a school-based health center (SBHC) weight management intervention.

METHODS

We first conducted parent and adolescent interviews on views and experiences about obesity while convening a community advisory council (CAC) recruited from two participating urban New Mexico high schools. Thematic findings from the interviews were analyzed with the CAC to develop culturally and developmentally appropriate intervention materials.

RESULTS

Themes from the parent and adolescent interviews included general barriers/challenges, factors influencing motivation, and change facilitators. The CAC and university-based research team reached consensus on the final content of nutrition and physical activity topics to produce a DVD and clinician toolkit through six monthly sessions. These materials used in the SBHC intervention resulted in a greater reduction of body mass index when compared to adolescents receiving standard care.

CONCLUSIONS

Formative assessment using an adaptive CBPR approach resulted in the creation of culturally and age appropriate weight reduction materials that were acceptable to study participants. This trial is registered with ClinicalTrials.gov NCT00841334.

School-based health center intervention improves body mass index in overweight and obese adolescents

Adolescents Committed to Improvement of Nutrition and Physical Activity (ACTION) was undertaken to determine feasibility of a school-based health center (SBHC) weight management program. Two urban New Mexico SBHCs were randomized to deliver ACTION or standard care. ACTION consisted of eight visits using motivational interviewing to improve eating and physical activity behavior. An educational nutrition and physical activity DVD for students and a clinician toolkit were created for use as menu of options. Standard care consisted of one visit with the SBHC provider who prescribed recommendations for healthy weight. Sixty nondiabetic overweight/obese adolescents were enrolled. Measures included BMI percentile, waist circumference, insulin resistance by homeostasis model assessment (HOMA-IR), blood pressure, triglycerides, and HDL-C levels. Pre- to postchanges for participants were compared between groups. Fifty-one students (mean age 15 years, 62% female, 75% Hispanic) completed pre- and postmeasures. ACTION students (n = 28) had improvements in BMI percentile (P = 0.04) and waist circumference (P = 0.04) as compared with students receiving standard care (n = 23). No differences were found between the two groups in blood pressure, HOMA-IR, triglycerides, and HDL-C. The ACTION SBHC weight management program was feasible and demonstrated improved outcomes in BMI percentile and waist circumference.

An adaptive community-based participatory approach to formative assessment with high schools for obesity intervention*

BACKGROUND

In the emerging debate around obesity intervention in schools, recent calls have been made for researchers to include local community opinions in the design of interventions. Community-based participatory research (CBPR) is an effective approach for forming community partnerships and integrating local opinions. We used CBPR principles to conduct formative research in identifying acceptable and potentially sustainable obesity intervention strategies in 8 New Mexico school communities.

METHODS

We collected formative data from 8 high schools on areas of community interest for school health improvement through collaboration with local School Health Advisory Councils (SHACs) and interviews with students and parents. A survey based on formative results was created to assess acceptability of specific intervention strategies and was provided to SHACs. Quantitative data were analyzed using descriptive statistics while qualitative data were evaluated using an iterative analytic process for thematic identification.

RESULTS

Key themes identified through the formative process included lack of healthy food options, infrequent curricular/extracurricular physical activity opportunities, and inadequate exposure to health/nutritional information. Key strategies identified as most acceptable by SHAC members included healthier food options and preparation, a healthy foods marketing campaign, yearly taste tests, an after-school noncompetitive physical activity program, and community linkages to physical activity opportunities.

CONCLUSION

An adaptive CBPR approach for formative assessment can be used to identify obesity intervention strategies that address community school health concerns. Eight high school SHACs identified 6 school-based strategies to address parental and student concerns related to obesity.

Acanthosis nigricans predicts the clustering of metabolic syndrome components in Hispanic elementary school-aged children

BACKGROUND

Acanthosis nigricans (AN) is a dermatologic condition associated with hyperinsulinemia, a marker of insulin resistance that is the principal abnormality in metabolic syndrome (MetS). We examined the association of AN with the clustering of MetS components.

METHODS

A cross-sectional study was conducted in an urban school-based health center in New Mexico. Students without diabetes were evaluated for AN, a family history of type 2 diabetes, body mass index (BMI), and MetS components. The clustering of MetS components by BMI category and AN status was assessed by comparing the group means of summed average z-scores of fasting insulin, triglycerides, high-density lipoprotein-cholesterol, and systolic blood pressure among the students. A multivariate model with BMI category and AN status controlling for Tanner stage was performed to identify the variables associated with the clustering of MetS components.

RESULTS

Complete data were available for 90 children (age, 9.7±1.4 years; 94% Hispanic; 60% female). In multivariate modeling of MetS cluster z-score, significant differences were found between the students with BMI <85th percentile [-0.27; 95% confidence interval (95% CI)=-0.42 to -0.11] and (a) the students with BMI 85th-94.9th percentile with AN (0.74; 95% CI=0.17-1.31) and (b) the students with BMI ≥95th percentile with AN (0.86; 95% CI=0.54-1.18). No significant differences in the MetS cluster z-score were seen between the students with BMI <85th percentile and those with BMI 85th-94.9th percentile without AN (0.24; 95% CI=-0.33 to 0.81) or those with BMI ≥95th percentile without AN (0.31; 95% CI=-0.13 to 0.75).

CONCLUSIONS

Overweight/obese Hispanic elementary school-aged children with AN exhibit clustering of MetS components and could benefit from early intervention.

The "ins" and "outs" of provider-parent communication: perspectives from adolescent primary care providers on challenges to forging alliances to reduce adolescent risk

PURPOSE

For several decades, the goal to protect adolescents' confidentiality in addition to state and professional mandates to provide confidential health services have sometimes outweighed the interest of involving parents in risk reduction efforts. More recently, experts acknowledge that a balance must be found between maintaining adolescent confidentiality and involving parents in preventing poor adolescent outcomes resulting from risky behaviors. The purpose of this research was to elucidate the challenges in and identify solutions to realizing this newer vision in the primary care setting.

METHODS

We conducted a qualitative study featuring in-depth interviews with 37 primary care providers among whom a significant component of their practice involved adolescent patients. Purposeful sampling was aimed at a diversity of gender, practice specialty, practice venues, and geographic areas.

RESULTS

We identified individual and structural barriers and facilitators to involving parents in their adolescents' primary care. Barriers included parents' lack of knowledge and awareness of their children's risk behaviors; providers time constraints and competing clinical demands, concerns for confidentiality and developing a trusting relationship with the child; and legal and system requirements that limit engagement with parents. Facilitators included interest and for some, planned approaches by the provider to engage the parent; encouragement by the provider to the adolescent to communicate with a trusted adult about their risky behavior; and opportunities to educate the parent about risk reduction in general.

CONCLUSION

Opportunities for further research on strategies to improve communication and develop a partnership between providers and parents are described.

Implementation of a walking school bus: lessons learned

BACKGROUND

Obesity is rapidly becoming the most common chronic medical condition affecting children. To address this crisis, an Albuquerque, New Mexico, elementary school partnered with University of New Mexico researchers and conducted a Walking School Bus (WSB). The purpose of this article is to examine the feasibility of implementing a WSB.

METHODS

This pilot study featured 2 WSBs conducted for 10 weeks with kindergarten through fifth-grade students from a predominantly Hispanic elementary school. Qualitative and quantitative data, including coordinator field notes, attendance records, surveys of student and parent satisfaction, and a focus group, were used to evaluate feasibility.

RESULTS

Student and adult participants expressed a high degree of enthusiasm regarding their involvement in the WSB. Participants uniformly indicated that the WSB provided a supportive and safe environment to promote social interaction and physical activity. Conducting a WSB in an urban, underserved school district is feasible but requires attention to ensure participants' involvement and safety. In particular, it is recommended to begin the planning process early to enhance investment from key stakeholders.

CONCLUSION

Effective, low-cost interventions are increasingly desired as solutions to the problem of obesity. The WSB has emerged as a promising strategy to address obesity and encourage partnerships across different social levels. Further research is necessary to assess the logistical challenges associated with conducting a large-scale WSB trial and whether such efforts lead to reductions in obesity risk factors.

Acanthosis nigricans and diabetes risk factors: prevalence in young persons seen in southwestern US primary care practices

PURPOSE

Evidence shows acanthosis nigricans is often associated with hyperinsulinemia and may indicate increased risk of type 2 diabetes mellitus. The purpose of this study was to determine the association of acanthosis nigricans with type 2 diabetes risk factors and disease in young persons.

METHODS

We conducted a cross-sectional study in the Research in Outpatient Settings Network, a practice-based research network in southwestern US communities. Participating clinicians (N = 96) collected data on children and young adults aged 7 to 39 years seen during a 2-week sampling period. The main outcomes were the prevalence of acanthosis nigricans, type 2 diabetes risk factors (ethnicity, family history of type 2 diabetes, hypertension, overweight/obesity), type 2 diabetes, and the relationships among these.

RESULTS

Among 1,133 patients sampled, risk factors for type 2 diabetes were common: 69% had a family history of the disease; 3% of children (aged 7 to 19 years) and 12% of adults had hypertension; 43% of children and 73% of adults were overweight or obese; and 80% were members of ethnic minorities. Acanthosis nigricans was found in 17% of children and 21% of adults. Among children and adults alike, the more type 2 diabetes risk factors that were present, the higher the prevalence of acanthosis nigricans (P <.001). The prevalence ratio for type 2 diabetes in patients with acanthosis nigricans was 1.97 (95% confidence interval, 1.18-3.27; P = .01) after controlling for age, body mass index, and the number of type 2 diabetes risk factors. Clinicians reported that the identification of acanthosis nigricans frequently led to discussions about lifestyle modification for decreasing the risk of type 2 diabetes.

CONCLUSIONS

Patients with acanthosis nigricans are likely to have multiple risk factors for type 2 diabetes. Acanthosis nigricans may be an independent risk factor for this disease. Detection of acanthosis nigricans may help clinicians more rapidly identify high-risk individuals for diabetes counseling.

Lacrimal fossa block: an audit of a minimally invasive regional anaesthetic technique for endoscopic dacryocystorhinostomy (DCR)

The lacrimal fossa block (LFB), a new development to provide regional anaesthesia for endoscopic dacryocystorhinostomy, is reported. Cadaveric study showed that the block needle, inserted as described, made direct contact with the periosteum of the frontal process of the maxilla within the lacrimal fossa. This technique enables both relevant divisions of the trigeminal nerve to be anaesthetized through a single entry site and, as this injection is confined to the anterior part of the orbit, ocular complications are minimized. An audit of 66 patients has shown that this technique, combined with standard intranasal local anaesthesia, provides good intraoperative analgesia, causes minimal diplopia and has a high level of patient acceptability.

Absorption of lidocaine during aspiration anesthesia of the airway

STUDY OBJECTIVE

To determine the optimal solution to use when anesthetizing the airway by aspiration of lidocaine.

DESIGN

Randomized, double-blind clinical study.

SETTING

University hospital.

PATIENTS

96 adult ASA physical status 1,II, and III patients, scheduled for diagnostic flexible bronchoscopy.

INTERVENTIONS

Patients were randomized to receive one of 5 solutions of lidocaine: Group A (n = 16): 1% lidocaine, 0.2 mL. kg(-1); Group B (n = 16): 1.5% 0.2 mL. kg(-1); Group C (n = 32): 2% 0.2 mL. kg(-1); Group D (n = 16): 1% 0.3 mL. kg(-1), and Group E (n = 16): 2% 0.3 mL. kg(-1). Fiberoptic bronchoscopy was performed after the airway was anesthetized with this aspiration technique, using the assigned lidocaine solution. The scope was manipulated in the trachea to test for anesthesia.

MEASUREMENTS AND MAIN RESULTS

Successful airway anesthesia was determined by tolerance to bronchoscopy without sustained coughing, and also by the number of lidocaine supplements, if any, that were given via the bronchoscope. Arterial plasma concentrations of lidocaine were measured in 33 patients from Groups C, D, and E. All solutions provided equally effective anesthesia of the airway. All patients tolerated endoscopy through the vocal cords, and 94 patients required no supplementary anesthesia, or only one dose of lidocaine, during bronchoscopy to the carina. The highest peak plasma concentrations of lidocaine were 5.02 and 6.28 microg. mL. No patient had signs of toxicity.

CONCLUSIONS

This technique produced anesthesia of the airway to the carina, safely, suitable for awake intubation, in 94 of 95 patients. The use of 1% lidocaine, 0.2 to 0.3 mL. kg(-1), so that the volume is 10 to 20 mL, is recommended.

Anesthesia of the airway by aspiration of lidocaine

PURPOSE

Lidocaine instilled onto to the back of the tongue of a supine subject and aspirated has been reported to provide effective topical anesthesia of the airway. The purpose of this study was to observe endoscopically the fate of lidocaine so instilled and document the efficacy of anesthesia for awake fibreoptic intubation.

METHODS

In Part I of the study, a fibreoptic bronchoscope was positioned in the pharynx of three volunteers lying supine and the route followed by tinted lidocaine solution instilled onto the back of the protruded tongue during mouth breathing was observed. In Part 2, the airway of 39 patients requiring awake fibreoptic intubation was anesthetized by having them gargle twice with 5 ml lidocaine 2%, followed by instillation of 0.2 ml-kg(-1) or 20 ml lidocaine 1.5% (whichever was less) onto the dorsum of their tongues as described above. The efficacy of anesthesia was scored by the patient reaction (coughing or gagging) to instrumentation in the pharynx, at the glottis, and in the trachea; to passage of the tracheal tube into the trachea; and to the presence of the tube in the trachea.

RESULTS

Lidocaine instilled on to the back of the tongue was swallowed initially but ultimately pooled in the pharynx and was aspirated. In all patients the trachea was intubated without requiring supplemental lidocaine, and all but one patient tolerated the tracheal tube in situ.

CONCLUSION

A combination of lidocaine gargles and lidocaine instilled on to the back of the tongue and aspirated provides effective anesthesia of the pharynx, larynx, and trachea for awake fibreoptic intubation.

An audit of induction of anaesthesia in neonates and small infants using pulse oximetry

The frequency and severity of hypoxaemia during induction of anaesthesia in neonates and small infants at the Norfolk and Norwich Hospital, a district general hospital, was compared, using pulse oximetry, with that of the nearest specialist hospital, the Queen Elizabeth Hospital for Sick Children in London. There were differences in staffing and the choice of anaesthetic techniques between the hospitals. One third of the patients in both hospitals experienced desaturation of more than 5% (moderate or severe hypoxaemia) at one or more recordings during induction. The highest incidence of hypoxaemia was associated with awake intubation. There was no statistical difference in the incidence or severity of hypoxaemia between the hospitals. In the district general hospital, moderate or severe hypoxaemia of greater than 30 s duration was more likely if an anaesthetist with a regular paediatric operating list was not present at induction (p < 0.01).

Rupture of membranes before the onset of spontaneous labour increases the likelihood of instrumental delivery

We studied obstetric outcome in 350 consecutive nulliparous women in spontaneous labour and term pregnancy. Women who presented with rupture of membranes before the onset of contractions were more likely to deliver by forceps compared with those in whom contractions preceded rupture of membranes. This increased likelihood of instrumental delivery was significant with and without the use of extradural analgesia in labour (P less than 0.05 and P less than 0.001, respectively). Furthermore, significantly more women with premature rupture of membranes received extradural analgesia in labour (P less than 0.01). We conclude that any study which aims to examine the influence of extradural analgesia on the outcome of delivery should include premature rupture of membranes as a bias factor.

Longitudinal study of serum antibody response to bovine corneal protein (BCP 54) in Behçet's disease

Serum samples from a patient diagnosed as having active Behçet's syndrome with iritis were evaluated by the enzyme-linked immunosorbent assay for antibodies against a purified bovine corneal protein, molecular weight 54,000 daltons (BCP 54). Significantly elevated antibody levels to BCP 54 were found in all serum samples collected over a 2-year period. Anti-BCP 54 antibody levels remained within a very narrow range, at least twofold higher than those of controls. In contrast, no antibody to retinal S antigen was detected. These results indicate the presence of specific anti-BCP 54 autoantibodies in sera from a Behçet's patient and suggest that autoantibodies may play a role in the etiopathogenesis of uveitis.

Studies on a new lymphocyte mitogen from Bordetella pertussis. I. Induction of proliferation and polyclonal antibody formation

Pertussis B mitogen (PBM), isolated from culture supernatant fluids of Bordetella pertussis, is a potent mitogen for mouse and human lymphocytes. In mice, > 95% of the blast cells recovered from PBM cultures bear surface immunoglobulins. Therefore, PBM seems to induce proliferation of mouse B lymphocytes, but not T cells. The proliferative response observed is nonspecific because cells from all mouse strains tested, including germfree animals, are responsive. Moreover, the mitogenic activity of PBM is independent of T lymphocytes, macrophages, or serum factors. When human peripheral blood or cord blood lymphocytes are cultured in the presence of PBM, a high level of thymidine incorporation by these cells is detected. Furthermore, PBM can induce polyclonal antibody formation by both mouse and human lymphocytes. Despite similar methods of isolation, PBM is distinct from the lymphocytosis-promoting factor of B. pertussis, a previously described T cell mitogen.

The in vitro effects of Bordetella pertussis lymphocytosis-promoting factor on murine lymphocytes. IV. Generation, characterization, and specificity of cytotoxic lymphocytes

Cytotoxic effector lymphocytes were induced in cultures of mouse spleen or lymph node cells by lymphocytosis promoting factor (LPF). The LPF-activated cytotoxic cells: (a) were not generated unless proliferation occurred; (b) sedimented in the lighter density fraction of a bovine serum albumin gradient; (c) were large, blast-like cells; and (d) were lysed by Thy-1.2 antiserum plus complement and, therefore, were T cells. Neither LPF alone nor supernates from stimulated cultures were cytotoxic. Unlike the situation with concanavalin A and phytohemagglutinin P, LPF-stimulated cytotoxic effector lymphocytes required no further addition of mitogen for maximal cytotoxicity. The effector cells displayed specificity, destroying only allogeneic but not syngeneic normal cells; in the case of tumor cells, both allogeneic and syngeneic cells werelysed in the absence of added mitogen. The reason for differentiated cytotoxicity toward syngeneic tumor and normal cells is not clear but may have some relevance to in vivo tumor rejection initiated by Bordetella pertussis.

The in vitro effects of Bordetella pertussis lymphocytosis-promoting factor on murine lymphocytes. III. B-cell dependence for T-cell proliferation

The nature of the helper lymphocytes in lymphocytosis-promoting factor (LPF)-induced proliferation was explored. Removal of macrophages from adherent splenocytes by either carbonyl-iron incubation or passage through Sephadex G-10 columns did not affect their synergistic function. Nor did cytolysis with Thy-1.2 antiserum and complement. The helper cells were found to be surface immunoglobulin-positive (sIg+) because they are retained by anti-Ig columns, susceptible to lysis by rabbit anti-mouse immunoglobulin and complement, and occurred in the sIg+ fractions of splenocytes after separation on the fluorescence-activated cell sorter. Further delineation of the surface markers on helper cells showed that complement receptors are not the determining marker for synergistic function. The requirement for B-helper cells in the stimulation of T lymphocytes by LPF is unique for a mouse of T-cell mitogen.

The mitogenic effect of the lymphocytosis promoting factor from Bordetella pertussis on human lymphocytes

The purified lymphocytosis promoting factor (LPF) from Bordetella pertussis was found to be a potent mitogen for peripheral blood lymphocytes (PBL) from normal adults as well as for cord blood lymphocytes. Proliferation occurred in autologous plasma or fetal calf serum, regardless of previous exposure to pertussis infection or immunization. Only one adult human serum, from a physician constantly working with B. pertussis, inhibited the mitogenic response to LPF and this serum was shown to contain precipitating antibody against LPF. The proliferative effect of LPF was characteristic of a "nonspecific" mitogen and not of antigen stimulation of sensitized cells.LPF, phytohemagglutinin, and concanavalin A were approximately equal in potency although variation occurred depending upon the cell donor. Experiments with lymphocyte subpopulations obtained by rosetting techniques employing sheep erythrocytes, mouse erythrocytes, and sheep erythrocytes coated with antibody and complement suggested the requirement of a multicellular system for LPF mitogencity.PBL from most patients with chronic lymphatic leukemia and lymphosarcoma cell leukemia were even less responsive to LPF than to phytohemagglutinin, whereas PBL from patients with lymphosarcoma usually responded to both mitogens. It can be inferred from the results of experiments with both normal and leukemic cells that LPF, which is a murine thymus-derived (T)-cell mitogen, is also a T-cell mitogen for human PBL. The exact cell requirement and mode of action, however, are as yet unknown.
