Item Attitudes About the Use of Newborn Dried Blood Spots for Research: A Survey of Underrepresented Parents(Elsevier, 2015-09) Hendrix, Kristin S.; Meslin, Eric M.; Carroll, Aaron E.; Downs, Stephen M.; Department of Pediatrics, IU School of MedicineObjective To identify the relative importance of factors that impact parents’ attitudes toward use of their child’s dried newborn blood spots for research purposes. Methods Respondents were parents aged 18 and older with at least one child aged 17 or younger born in Indiana visiting an urban pediatrics clinic. They were asked to rate the acceptability of hypothetical scenarios involving the research use of blood spots. Three pieces of information varied between the scenarios: 1) who would be conducting the research; 2) whether the child’s identity would be linked to the spots; and 3) whether and how often the parents’ consent would be sought before the research began. Results A total of 506 predominantly black and low-income parents completed the survey. The conjoint analysis model showed good fit (Pearson’s R = 0.998, P < .001). The rank order of factors affecting parents’ attitudes was: 1) consent (importance score = 64.9), 2) whether the child’s identity was linked to the spot (importance score = 19.4), and 3) affiliation of the researcher using the spots (importance score = 14.6). Respondents preferred being asked for their consent each time their children’s spots would be used. They preferred that the children’s identity not be linked to the spots and that the research be conducted by university researchers, though these issues had less impact on attitudes than consent. Conclusions Parents strongly prefer that consent be sought for each use of their children’s blood spots. These findings have implications for future research and policy-making decisions.Item Early cow's milk introduction is associated with failed personal-social milestones after 1 year of age(Springer-Verlag, 2014-07) Bennett, William E.; Hendrix, Kristin S.; Thompson-Fleming, Rachel T.; Downs, Stephen M.; Carroll, Aaron E.; Department of Pediatrics, IU School of MedicineBoth the American Academy of Pediatrics (AAP) and the Institute of Medicine (IOM) recommend delaying the introduction of cow's milk until after 1 year of age due to its low absorbable iron content. We used a novel computerized decision support system to gather data from multiple general pediatrics offices. We asked families whether their child received cow's milk before 1 year of age, had a low-iron diet, or used low-iron formula. Then, at subsequent visits, we performed a modified developmental assessment using the Denver II. We assessed the effect of early cow's milk or a low-iron diet on the later failure of achieving developmental milestones. We controlled for covariates using logistic regression. Early cow's milk introduction (odds ratio (OR) 1.30, p = 0.012), as well as a low-iron diet or low-iron formula (OR 1.42, p < 0.001), was associated with increased rates of milestone failure. Only personal-social milestones (OR 1.44, p = 0.002) showed a significantly higher rate of milestone failure. Both personal-social (OR 1.42, p < 0.001) and language (OR 1.22, p = 0.009) showed higher rates of failure in children with a low-iron diet. CONCLUSIONS: There is an association between the introduction of cow's milk before 1 year of age and the rate of delayed developmental milestones after 1 year of age. This adds strength to the recommendations from the AAP and IOM to delay cow's milk introduction until after 1 year of age.Item An emerging field of research: challenges in pediatric decision making(SAGE Publications, 2015-04) Lipstein, Ellen A.; Brinkman, William B.; Fiks, Alexander G.; Hendrix, Kristin S.; Kryworuchko, Jennifer; Miller, Victoria A.; Prosser, Lisa A.; Ungar, Wendy J.; Fox, David; Department of Pediatrics, IU School of MedicineThere is growing interest in pediatric decision science, spurred by policies advocating for children's involvement in medical decision making. Challenges specific to pediatric decision research include the dynamic nature of child participation in decisions due to the growth and development of children, the family context of all pediatric decisions, and the measurement of preferences and outcomes that may inform decision making in the pediatric setting. The objectives of this article are to describe each of these challenges, to provide decision researchers with insight into pediatric decision making, and to establish a blueprint for future research that will contribute to high-quality pediatric medical decision making. Much work has been done to address gaps in pediatric decision science, but substantial work remains. Understanding and addressing the challenges that exist in pediatric decision making may foster medical decision-making science across the age spectrum.Item Ethics and Childhood Vaccination Policy in the United States(American Public Health Association, 2016-02) Hendrix, Kristin S.; Sturm, Lynne A.; Zimet, Gregory D.; Meslin, Eric M.; Department of Pediatrics, IU School of MedicineChildhood immunization involves a balance between parents' autonomy in deciding whether to immunize their children and the benefits to public health from mandating vaccines. Ethical concerns about pediatric vaccination span several public health domains, including those of policymakers, clinicians, and other professionals. In light of ongoing developments and debates, we discuss several key ethical issues concerning childhood immunization in the United States and describe how they affect policy development and clinical practice. We focus on ethical considerations pertaining to herd immunity as a community good, vaccine communication, dismissal of vaccine-refusing families from practice, and vaccine mandates. Clinicians and policymakers need to consider the nature and timing of vaccine-related discussions and invoke deliberative approaches to policy-making.Item Human Papillomavirus Vaccine Initiation among 9-13-Year-Olds in the United States(Elsevier, 2015) Donahue, Kelly L.; Hendrix, Kristin S.; Sturm, Lynne A.; Zimet, Gregory D.; Department of Pediatrics, IU School of MedicineOBJECTIVE: The quadrivalent and 9-valent human papillomavirus (HPV) vaccines are licensed for administration among 9-26-year-old males and females, with routine vaccination recommended for 11-12-year-olds. Despite the availability of the vaccine at younger ages, few studies have explored vaccine uptake prior to age 13, and national HPV vaccination surveillance data is limited to 13-17-year-olds. Our objective was to examine rates and predictors of HPV vaccine initiation among 9-13-year-olds in the United States. METHODS: A national sample of mothers of 9-13-year-olds in the United States (N=2,446) completed a 2014 Web-based survey assessing socio-demographic characteristics, child's HPV vaccination history, provider communication regarding the vaccine, and other attitudes and behaviors pertaining to vaccination and healthcare utilization. The main outcome measure was child's initiation of the HPV vaccine (i.e., receipt of one or more doses). RESULTS: Approximately 35% of the full sample and 27.5% of the 9-10-year-olds had initiated HPV vaccination. Females were more likely than males to have initiated HPV vaccination by the age of 13 but not by younger ages. Strength of health provider recommendation regarding HPV vaccination was a particularly salient predictor of vaccine initiation. CONCLUSIONS: Approximately a third of children may be initiating the HPV vaccine series before or during the targeted age range for routine administration of the vaccine. Because coverage remains below national targets, further research aimed at increasing vaccination during early adolescence is needed. Improving providers' communication with parents about the HPV vaccine may be one potential mechanism for increasing vaccine coverage.Item The influence of resuscitation preferences on obstetrical management of periviable deliveries(Nature Publishing Group, 2015-03) Edmonds, Brownsyne Tucker; McKenzie, Fatima; Hendrix, Kristin S.; Perkins, Susan M.; Zimet, Gregory D.; Department of Obstetrics & Gynecology, IU School of MedicineObjective Determine the relative influence of patient's resuscitation preferences on periviable delivery management. Methods Surveyed 295 obstetrician-gynecologists about managing periviable preterm premature rupture of membranes. Across 10 vignettes, we systematically varied gestational age; occupation; method of conception; and resuscitation preference. Physicians rated their likelihood (0-10) of proceeding with induction, steroids, and cesarean. Data were analyzed via conjoint analysis. Results 205 physician responses were included. Median ratings for management decisions were: induction 1.89; steroids 5.00; cesarean for labor 3.89; cesarean for distress 4.11. Gestational age had the greatest influence on physician ratings across all decisions (importance values ranging from 72.6-86.6), followed by patient's resuscitation preference (range= 9.3-21.4). Conclusion Gestational age is weighted more heavily than patients’ resuscitation preferences in obstetricians’ decision-making for periviable delivery management. Misalignment of antenatal management with parental resuscitation preferences may adversely affect periviable outcomes. Interventions are needed to facilitate more patient-centered decision-making in periviable care.Item Pediatricians’ Responses to Printed Clinical Reminders: Does Highlighting Prompts Improve Responsiveness?(Elsevier, 2015-03) Hendrix, Kristin S.; Downs, Stephen M.; Carroll, Aaron E.; Department of Pediatrics, IU School of MedicineObjective Physicians typically respond to roughly half of the clinical decision support prompts they receive. This study was designed to test the hypothesis that selectively highlighting prompts in yellow would improve physicians' responsiveness. Methods We conducted a randomized controlled trial using the Child Health Improvement Through Computer Automation clinical decision support system in 4 urban primary care pediatric clinics. Half of a set of electronic prompts of interest was highlighted in yellow when presented to physicians in 2 clinics. The other half of the prompts was highlighted when presented to physicians in the other 2 clinics. Analyses compared physician responsiveness to the 2 randomized sets of prompts: highlighted versus not highlighted. Additionally, several prompts deemed high priority were highlighted during the entire study period in all clinics. Physician response rates to the high-priority highlighted prompts were compared to response rates for those prompts from the year before the study period, when they were not highlighted. Results Physicians did not respond to prompts that were highlighted at higher rates than prompts that were not highlighted (62% and 61%, respectively; odds ratio 1.056, P = .259, NS). Similarly, physicians were no more likely to respond to high-priority prompts that were highlighted compared to the year before, when the prompts were not highlighted (59% and 59%, respectively, χ2 = 0.067, P = .796, NS). Conclusions Highlighting reminder prompts did not increase physicians' responsiveness. We provide possible explanations why highlighting did not improve responsiveness and offer alternative strategies to increasing physician responsiveness to prompts.Item POINT: Should Childhood Vaccination Against Measles Be a Mandatory Requirement for Attending School? Yes.(Elsevier, 2015-10) Silverman, Ross D.; Hendrix, Kristin S.; Department of Health Policy, Richard M. Fairbanks School of Public HealthItem Rebuttal From Prof Silverman and Dr Hendrix.(Elsevier, 2015-10) Silverman, Ross D.; Hendrix, Kristin S.; Department of Health Policy, Richard M. Fairbanks School of Public HealthItem Screen Exposure and BMI Status in 2-11 Year Old Children(Sage, 2014-06) Hendrix, Kristin S.; Carroll, Aaron E.; Downs, Stephen M.; Department of Pediatrics, IU School of MedicineObjective. To measure the relationship between screen exposure and obesity in a large, urban sample of children and to examine whether the relationship is moderated by sociodemographics. Methods. We asked parents of 11 141 children visiting general pediatrics clinics if the child had a television (TV) in the bedroom and/or watched more than 2 hours of TV/computer daily. We measured children’s height and weight, then used logistic regression to determine whether screen exposure indicators predicted obesity (body mass index ≥85th percentile) and interacted with race/ethnicity, sex, age, and health care payer. Results. Having a TV in the bedroom predicted obesity risk (P = .01); however, watching TV/computer for more than 2 hours a day did not (P = 0.54). There were no interactions. Conclusions. Asking whether a child has a TV in the bedroom may be more important than asking about duration of screen exposure to predict risk for obesity.
