Management of Croup in the Emergency Department: The Role of Multidose Nebulized Epinephrine.

OBJECTIVES: Croup occasionally requires medical intervention for respiratory distress. Mainstays of treatment are corticosteroids and nebulized epinephrine. Diagnosis and assessment of severity remain clinical. Safety of discharge from an emergency department (ED) after treatment with corticosteroids and 1 nebulized epinephrine has been established. No evidence exists regarding risk associated with discharge after multidose nebulized epinephrine. Many patients requiring multidose nebulized epinephrine are reflexively admitted. The purpose of this study was to provide a descriptive analysis of the current management of croup, specifically patients requiring multidose nebulized epinephrine. METHODS: The Pediatric Health Information System was used to extract information on patients diagnosed with croup age 0 to 11 years, evaluated in pediatric EDs from 2004 to 2014, who received corticosteroids and at least 1 nebulized epinephrine. We retrospectively assessed patients requiring multidose nebulized epinephrine, evaluating risk of return for additional care associated with discharges and reviewing admissions for markers of disease severity. RESULTS: A total of 95,403 patients were identified. Those requiring corticosteroids and multidose nebulized epinephrine (N = 8084) were less likely to return for further care if discharged from the ED (5.4% return single dose, 0.8% return multidose: P < 0.0001) and were admitted at a higher rate (10.7% admission single dose, 70.5% admission multidose: P < 0.0001). Of those admitted, only 31.7% received more than 2 treatments. CONCLUSIONS: Patients requiring single-dose nebulized epinephrine are managed differently than those requiring multidose nebulized epinephrine. There is likely a role for multidose nebulized epinephrine in the outpatient management of croup. A prospective study is needed.

Adverse Pregnancy and Neonatal Outcomes Among Marshallese Women Living in the United States.

Objective Despite heterogeneity among Pacific Islanders, most studies aggregate them regardless of origin. Thus, limited information is available about perinatal outcomes among various subgroups of Pacific Islanders in the United States, including immigrants from the Republic of the Marshall Islands. We sought to evaluate perinatal outcomes among Marshallese women. Methods We conducted a cross-sectional study of women with at least one singleton live birth between 1997 and 2013 in two Arkansas counties using birth certificate data from the Arkansas Department of Health. Unadjusted and adjusted prevalence ratios (PR) and 95% confidence intervals (CI) were calculated from modified Poisson regression models. Results Of the 91,662 singleton births in both counties during the study period, 2488 were to Marshallese women. In adjusted analyses, Marshallese women had higher prevalence of "other medical risk factors" (PR = 1.47; 95% CI 1.30, 1.65) than NH White women. Marshallese women had higher rates of precipitous labor and fetal distress during labor compared to NH White women (PR = 2.65; 95% CI 2.22, 3.17 and 1.89; 95% CI 1.62, 2.21, respectively). Marshallese were also more likely to have tocolysis (PR = 1.43; 95% CI 1.16, 1.76), forceps (PR = 1.68; 95% CI 1.16, 2.43) or vacuum (PR = 1.89; 95% CI 1.60, 2.22) used in delivery and cesarean section (PR = 1.13; 95% CI 1.01, 1.27). Marshallese infants had higher rates of anemia (PR = 3.10; 95% CI 2.01, 4.77), birth injury (PR = 2.13; 95% CI 1.50, 3.03), assisted ventilation < 30 min (PR = 2.11; 95% CI 1.64, 2.71), preterm birth (PR = 1.67; 95% CI 1.50, 1.83), and small-for-gestational age (PR = 1.25; 95% CI 1.12, 1.39) than NH White infants. Conclusions Marshallese women and infants had higher rates of adverse perinatal outcomes compared to their NH White counterparts. Additional studies are needed to determine if perinatal outcomes among the Marshallese differed from other Pacific Islander subgroups.

Long-Term Neurodevelopment of Low-Birthweight, Preterm Infants with Patent Ductus Arteriosus.

OBJECTIVE: To evaluate whether the presence of patent ductus arteriosus (PDA) in preterm infants worsens long-term neurodevelopmental outcomes. STUDY DESIGN: This was a secondary observational analysis of data from 1090 preterm low-birthweight infants in the Infant Health and Development Program (IHDP), a multicenter longitudinal cohort study of outcomes assessed from 3 to 18 years of age. Multivariable analysis was adjusted for IHDP treatment group (intervention or follow-up), birth weight, maternal race, maternal education, infant sex, maternal preconception weight, Home Observation Measurement of the Environment (HOME) total score at 12 months, neonatal health index, and gestational age. RESULTS: Of the 1090 patients (49% male) included in the analysis, 135 had a PDA. Mean birth weight (1322 g vs 1871 g; P < .0001) and gestational age (30.2 weeks vs 33.4 weeks, P < .0001) were lower and mean ventilator days (11.8 vs 1.3; P < .0001), vasopressor use (12.6% vs 1.2%; P < .0001), and congestive heart failure (8.9% vs 0.1%; P < .0001) were higher in the PDA group. There were no differences between the PDA and no-PDA groups in maternal education level and HOME total score at age 12 months. Multivariable analysis demonstrated no between-group differences in cognitive development or behavioral competence at age 3, 8, and 18 years. CONCLUSIONS: The presence of a PDA in moderately preterm, low-birthweight infants does not impact long-term neurodevelopmental outcomes.

A Cross-Sectional Study of Emergency Department Visits by Children After All-Terrain Vehicle Crashes, Motor Vehicle Crashes, and Sports Activities.

OBJECTIVES: All-terrain vehicle (ATV) crashes have been responsible for significant injuries among children, despite public education efforts. Our study examined pediatric ATV injury patterns in US emergency departments (EDs) compared with injuries after motor vehicle crash (MVC) and sports activities. METHODS: We studied 2006 to 2011 data from the Nationwide Emergency Department Sample. Children younger than 18 years and involved in ATV crashes, MVC, or sports activities were included. The primary outcome analyzed was a constructed binary measure identifying severe trauma, defined as injury severity score greater than 15. Logistic regression models were fit to determine the association between mechanism of injury and severe trauma. RESULTS: A total of 6,004,953 ED visits were identified. Of these, ATV crashes accounted for 3.4%, MVC accounted for 44.7%, and sports activities accounted for 51.9%. Emergency department visits after ATV crashes were more likely to result in admission (8%) and incur higher median charges ($1263) compared with visits after sports activities (1%, $1013). Visits after sports activities were 90% less likely to result in severe trauma when compared with ATV crash visits. Emergency department visits after ATV crashes result in severe injuries similar to those sustained in MVC (odds ratio, 1.03; P = 0.626). CONCLUSIONS: Pediatric ED visits after ATV crashes result in significant injuries and charges. Public health interventions such as education, legislation, and engineering are needed to reduce injuries among children and the subsequent ED visits for care. The impact of proven interventions may be greatest for children living in rural areas and among older children, 10 to 17 years old.

Factors associated with inpatient hospitalizations among patients aged 1 to 64 years with congenital heart defects, Arkansas 2006 to 2011.

BACKGROUND: Individuals with congenital heart defects (CHDs) have high hospital resource use. We sought to identify factors associated with hospital costs and multiple hospitalizations among individuals with CHDs. METHODS: Data from the 2006 to 2011 Healthcare Cost and Utilization Project Arkansas State Inpatient Databases were linked across encrypted patient identifiers to develop a cohort of Arkansas residents aged 1 to 64 years who were hospitalized at least once with a CHD during this time period. Infants were excluded because patient identifiers were missing for 18 to 52% each year. CHDs were identified using principal and secondary International Classification of Diseases, Ninth Revision, Clinical Modification diagnoses codes. All hospitalizations of individuals ever admitted with a CHD were included. Mean and median patient-level costs were estimated; the association of hospital costs and patient readmissions were examined with linear and logistic regression. RESULTS: There were 1,185,868 inpatient hospitalizations of Arkansas residents aged 1 to 64 years between 2006 and 2011; these were accrued by 603,925 patients. Of those, 2542 patients (0.42%) had at least one hospitalization with a CHD diagnosis. Total costs for these 2542 patients were $126,999,837 and they accumulated 7898 hospitalizations. Factors associated with increased costs included patient age, CHD type, cardiac procedures, and comorbidities. Factors associated with hospital readmission within 1 year included age, CHD type, expected payer, and comorbidities. CONCLUSION: Individuals with CHDs in Arkansas experience variation in hospital use and costs by patient characteristics. Future research should investigate factors associated with readmissions, cardiac procedures, and comorbidities, as these are strongly associated with hospital costs.

Population-based study of hospital costs for hospitalizations of infants, children, and adults with a congenital heart defect, Arkansas 2006 to 2011.

BACKGROUND: Congenital heart defects (CHDs) are common birth defects and are associated with high hospital costs. The objectives of this study were to assess hospitalization costs, across the lifespan, of patients with CHDs in Arkansas. METHODS: Data from the 2006 to 2011 Healthcare Cost and Utilization Project Arkansas State Inpatient Databases were used. We included hospitalizations of patients whose admission occurred between January 1, 2006, and December 31, 2011, and included a principal or secondary CHD ICD-9-CM diagnosis code (745.0-747.49, except 747.0 and 745.5 for preterm infants). Hospitalizations were excluded if they involved out-of-state residents, normal newborn births, or if missing data included age at admission, state of residence, or hospital charges. Children were defined as those < 18 years-old at time of admission. RESULTS: Between 2006 and 2011, there were 2,242,484 inpatient hospitalizations in Arkansas. There were 9071 (0.4%) hospitalizations with a CHD, including 5,158 hospitalizations of children (2.2% of hospitalizations among children) and 3,913 hospitalizations of adults (0.2% of hospitalizations of adults). Hospital costs for these CHD hospitalizations totaled $355,543,696. The average annual cost of CHD hospitalizations in Arkansas was $59,257,283 during this time period. Infants accounted for 72% of all CHD-related hospital costs; total costs of CHD hospitalizations for children were almost five times those of hospitalization costs for adults with CHD. CONCLUSION: Hospitalizations with CHDs account for a disproportionate share of hospital costs in Arkansas. Hospitalizations of children with CHD accounted for a higher proportion of total hospitalizations than did hospitalizations of adults with CHD.

Variation in child health care utilization by medical complexity.

Children with medical complexity (CMC) have multiple specialty need, technology dependence, and high health care utilization. The objective of this study is to profile types of pediatric health care utilization and costs by increasing levels of medical complexity. This is a cross-sectional study of the 2007, 2008 and 2009 Full-Year Data Sets from the Medical Expenditure Panel Survey. Medical complexity was defined by a higher number of positive items from the five question children with special health care needs (CSHCN) Screener. CMC were defined by ≥ 4 positive screener items. Outcomes included the number of inpatient, outpatient, and emergency department visits, associated costs and diagnoses, and reported satisfaction. ICD-9 codes were grouped by Clinical Classifications Software. Of 27,755 total study subjects ≤ 17 years, 4,851 had special needs and 541 were CMC. Older age, male gender, white/non-Hispanic race/ethnicity, and public insurance were all associated with medical complexity (all p < 0.001). CMC had an annual mean of 19 annual outpatient visits ($616) and 0.26 inpatient visits ($3,308), with other significant cost drivers including home health ($2,957) and prescriptions ($2,182). The most common reasons for non-CSHCN and less-complex CSHCN outpatient visits were viral illnesses, while the main reasons for CMC visits were for mental health. Compared to families without CSHCN, those with CMC have, on average, lower satisfaction with health care (8.4 vs. 8.9 out of 10, p < 0.001). Health care models for CMC should account for mental health conditions that may be driving high numbers of outpatient encounters.

Emergency Care of Children with Ambulatory Care Sensitive Conditions in the United States.

BACKGROUND: Ambulatory care sensitive (ACS) conditions are health problems that could be prevented or ameliorated with adequate access to primary care services. OBJECTIVES: To determine the extent to which ACS conditions account for care received by children in U.S. emergency departments (EDs) and the patient charges for this care. METHODS: A retrospective, cross-sectional analysis of the 2010 Nationwide Emergency Department Sample was performed. Patients 0-19 years of age were included and visits for ACS conditions were identified. Main outcome measures were the percentage of visits for ACS conditions, regression models predicting presentation for ACS conditions based on patient demographic characteristics, and ED charges for ACS ED visits. RESULTS: Of almost 30 million pediatric ED visits in the United States in 2010, 13.2% were for exclusively ACS conditions. Patients with public or no insurance were 1.2 times more likely than privately insured patients to present for an ACS condition. Lower household income (adjusted odds ratio [aOR] 1.49; 95% confidence interval [CI] 1.33-1.66) and younger patient age (aOR = 2.55; 95% CI 2.41-2.69) were also predictive of an ACS ED visit. The total of charges for ACS visits was almost $3 billion, of which publicly insured patients accounted for $1.5 billion. CONCLUSIONS: Almost one in seven U.S. pediatric ED visits may be preventable by quality primary care. Patients with public insurance and lower income are more likely than other groups to present with ACS conditions. Better access to and use of primary care services could reduce health care costs and relieve ED overcrowding.

Hospital utilization in adults with single ventricle congenital heart disease and cardiac arrhythmias.

OBJECTIVES: The study sought to identify the impact of cardiac arrhythmias on hospitalizations in adults with single ventricle (SV) congenital heart disease (CHD). BACKGROUND: Surgical advances have dramatically improved survival in patients with CHD. Cardiac arrhythmias and sudden cardiac death are common in adults with CHD. METHODS AND RESULTS: Data from 43 pediatric hospitals in the 2004 to 2011 Pediatric Health Information System database were used to identify patients ≥18 years of age admitted with International Classification of Diseases-9th Revision codes for a diagnosis of either hypoplastic left heart syndrome (HLHS), tricuspid atresia (TA) or common ventricle (CV), and a cardiac arrhythmia. Primary and secondary diagnoses, length of stay (LOS), hospital charges, and interventional procedures were determined. Multilevel models were used to evaluate differences in demographics, diagnoses, and clinical outcomes among the 3 subgroups (HLHS, TA, and CV). Interactions of charges with arrhythmia and admission year were examined using ANOVA. There were 642 admissions in 424 patients with SV CHD and an arrhythmia diagnosis. A single arrhythmia diagnosis was present in 454 admissions (71%). Total hospital charges were $80.7 million with mean charge per admission of $127,296 ± 243,094. The mean charge per hospital day was $16,653 ± 17,516 and increased across the study period (P < 0.01). Arrhythmia distributions were impacted by SV anatomic subtype (P < 0.001). Hospital resource utilization was significantly different among arrhythmia groups (P < 0.001). CONCLUSIONS: In adults with SV CHD, arrhythmias are affected by SV anatomic subtype and impact adversely upon hospital resource utilization.

Examination of mental health status and aggravation level among mothers of children with isolated oral clefts.

OBJECTIVE: To examine self-reported mental health status and aggravation level in mothers of children with isolated oral clefts. METHODS: Population-based sample of children (aged 4 to 9 years) with isolated oral clefts was enumerated from births from 1998 through 2003 in Arkansas, Iowa, and New York State. Mothers of 294 children completed the Mental Health Inventory 5-item questionnaire and Aggravation in Parenting Scale. The Mental Health Inventory and Aggravation in Parenting Scale scores, stratified by poor (Mental Health Inventory ≤ 67) and better (Mental Health Inventory > 67) mental health status or high (Aggravation in Parenting Scale ≤ 11), moderate (Aggravation in Parenting Scale = 12 to 15) and low (Aggravation in Parenting Scale = 16) aggravation, were compared by selected maternal and child characteristics. Mean scores for each instrument and proportion of mothers with poor mental health or high aggravation were compared with those reported in the National Survey of American Families. RESULTS: Mean scores for each instrument and proportion of mothers with poor mental health or high aggravation differed little from published data. Mothers with poor mental health tended to be less educated, to have lower household incomes, and to rate their health and their child's health lower than those in better mental health. Mothers with high aggravation tended to have lower household incomes, to have more children, and to rate their health and their child's health lower than those with moderate or low aggravation. CONCLUSIONS: Mothers of affected children were not more likely to experience poor mental health or high aggravation compared with published data; however, sociodemographic characteristics were associated with maternal psychosocial adaptation. Brief screeners for mental health and parenting administered during routine appointments may facilitate identifying at-risk caregivers.

Implementing provider-based sampling for the National Children's Study: opportunities and challenges.

BACKGROUND: The National Children's Study (NCS) was established as a national probability sample of births to prospectively study children's health starting from in utero to age 21. The primary sampling unit was 105 study locations (typically a county). The secondary sampling unit was the geographic unit (segment), but this was subsequently perceived to be an inefficient strategy. METHODS AND RESULTS: This paper proposes that second-stage sampling using prenatal care providers is an efficient and cost-effective method for deriving a national probability sample of births in the US. It offers a rationale for provider-based sampling and discusses a number of strategies for assembling a sampling frame of providers. Also presented are special challenges to provider-based sampling pregnancies, including optimising key sample parameters, retaining geographic diversity, determining the types of providers to include in the sample frame, recruiting women who do not receive prenatal care, and using community engagement to enrol women. There will also be substantial operational challenges to sampling provider groups. CONCLUSION: We argue that probability sampling is mandatory to capture the full variation in exposure and outcomes expected in a national cohort study, to provide valid and generalisable risk estimates, and to accurately estimate policy (such as screening) benefits from associations reported in the NCS.

Separation anxiety in children ages 4 through 9 with oral clefts.

Background : Psychosocial research on children with oral clefts (OCs), i.e., clefts of the lip, palate, or lip and palate, has suggested that these children may have higher rates of anxiety in general, but overall results have been equivocal. In this study we estimated the prevalence of separation anxiety disorder (SAD) in a population-based sample of children with OCs and identified associated risk factors. Methods : Parents of 279 children with OCs, identified through three state birth defect registries, responded to a postal survey that included the Separation Anxiety subscale of the Screen for Child Anxiety-Related Emotional Disorders (SCARED) and items regarding the child's OC and its sequelae, parent and child health, parent mental health, family structure, and socioeconomic status indicators. Associations with SA were evaluated using bivariate and multivariate statistics. Results : One quarter (24%) of the children screened positive for SAD, which was substantially higher than the U.S. child population estimates of 3% to 5%. OC-related impairments in speaking and eating more than doubled the risk of SAD, as did lower socioeconomic status and lower maternal health rating. Maternal mental health and marital status remained in the logistic model but were not significant. Conclusions : Children with OCs appear to be at increased risk for SAD as measured by the SCARED instrument. OC-related problems with speech and eating more than doubled the risk of SAD. The use of targeted screening tools may help refine our understanding of psychosocial adjustment in children with OCs.

Primary care physician experience with children with oral clefts in three states.

BACKGROUND: The experience of primary care physicians in Arkansas, Iowa, and New York treating children with oral clefts (OCs) was investigated, along with their knowledge and comfort caring for or referring these children. METHODS: A mail survey was conducted with all primary care physicians in Iowa and Arkansas, and a random sample of 4000 physicians in New York, selected from the American Medical Association (AMA) Master File. The final dataset consisted of 1435 usable surveys. Outcome measures were experience and comfort providing care to or referring children with OC. Differences between states were tested using Pearson or Kruskal-Wallis chi-square tests, or F-tests for differences in means. RESULTS: Two-thirds of respondents had provided care to a child with an OC since completing residency. Physicians were most comfortable providing routine care and much less comfortable providing counseling on cleft-related issues. Eighty percent had an organized cleft team to which they could refer. About two-thirds were very comfortable with the expertise available for surgical care, speech, and hearing; half were for dental care; only 40% were for behavioral or emotional counseling. Two-thirds were interested in continuing medical education (CME) on cleft care. CONCLUSIONS: Primary care physicians in all three states had little experience with children with OCs. This limited experience poses significant barriers to care. Increased experience during training and CME opportunities could improve knowledge and comfort with providing OC-related care. Increasing knowledge of referral options for team care and other cleft-related services could also help physicians when caring for children with OCs.

Prenatal diagnosis of orofacial clefts: association with maternal satisfaction, team care, and treatment outcomes.

OBJECTIVE: Prenatal diagnosis of an orofacial cleft is thought to allow mothers greater opportunity to become prepared for the special needs of an infant with a cleft and plan for the care of their child. Using a population-based sample, we determined which children were more likely to be diagnosed prenatally, and whether early diagnosis was associated with maternal satisfaction and treatment outcomes. DESIGN: Interviews were completed with 235 (49% of eligible) mothers of children ages 2 to 7 with orofacial clefts initially enrolled in the National Birth Defects Prevention Study from the Arkansas, Iowa, and New York sites. Maternal satisfaction with information, support, and treatment outcomes was compared between women who received a prenatal diagnosis and those who did not. RESULTS: Of 235 infants with clefts, 46 (19.6%) were identified prenatally. One third of mothers were somewhat or not satisfied with information provided by medical staff. Satisfaction did not vary by timing of the diagnosis. Infants diagnosed prenatally were no more likely to have received care provided by a recognized multidisciplinary cleft team (76%) than were infants diagnosed at birth (78%). Speech problems and facial appearance as rated by the mother did not vary by timing of the diagnosis. CONCLUSIONS: Timing of the cleft diagnosis did not alter maternal satisfaction with information, whether care was provided by a designated cleft team, or maternal perception of facial appearance or speech. Further research should determine whether prenatal diagnoses alter maternal anxiety or influence postnatal morbidity.

Interdisciplinary craniofacial teams compared with individual providers: is orofacial cleft care more comprehensive and do parents perceive better outcomes?

OBJECTIVE: The primary objective was to examine whether children with orofacial clefts received more comprehensive care and whether their parents perceived better outcomes if the care was delivered by interdisciplinary teams compared with individual providers. DESIGN: Data about services received and outcomes were collected from mothers of children with orofacial clefts. PARTICIPANTS: Mothers of children born between 1998 and 2003 with orofacial clefts from Arkansas, Iowa, and New York who participated in the National Birth Defects Prevention Study were eligible. MAIN OUTCOME MEASURE(S): Services and treatments received and maternal perception of cleft care, health status, aesthetics, and speech were evaluated by team care status. RESULTS: Of 253 children, 24% were not receiving team care. Of those with cleft lip and palate, 86% were enrolled in team care. Compared with children with team care, those without had fewer surgeries and were less likely to have seen a dentist, received a hearing test, or had a genetic consultation. Mothers of children lacking team care were twice as likely to give lower ratings for overall cleft care; maternal perceptions of global health, facial appearance, and speech did not differ by team care status. CONCLUSIONS: Recommended care tended to be received more often among those with team care. A larger, longitudinal study might answer questions about whether team care provides the best care and the role that type and severity of the condition and racial/ethnic differences play in the services received and outcomes experienced.

Control selection and participation in an ongoing, population-based, case-control study of birth defects: the National Birth Defects Prevention Study.

To evaluate the representativeness of controls in an ongoing, population-based, case-control study of birth defects in 10 centers across the United States, researchers compared 1997-2003 birth certificate data linked to selected controls (n = 6,681) and control participants (n = 4,395) with those from their base populations (n = 2,468,697). Researchers analyzed differences in population characteristics (e.g., percentage of births at > or =2,500 g) for each group. Compared with their base populations, control participants did not differ in distributions of maternal or paternal age, previous livebirths, maternal smoking, or diabetes, but they did differ in other maternal (i.e., race/ethnicity, education, entry into prenatal care) and infant (i.e., birth weight, gestational age, and plurality) characteristics. Differences in distributions of maternal, but not infant, characteristics were associated with participation by selected controls. Absolute differences in infant characteristics for the base population versus control participants were < or =1.3 percentage points. Differences in infant characteristics were greater at centers that selected controls from hospitals compared with centers that selected controls from electronic birth certificates. These findings suggest that control participants in the National Birth Defects Prevention Study generally are representative of their base populations. Hospital-based control selection may slightly underascertain infants affected by certain adverse birth outcomes.

Maternal reports of satisfaction with care and outcomes for children with craniosynostosis.

Craniosynostosis is a congenital deformity caused by premature fusion of cranial suture(s). Surgical outcomes of craniosynostosis have been well documented; however, limited published data are available regarding access to care and social and psychological health outcomes for children with craniosynostosis. The authors conducted a population-based, multistate study of maternal perceptions of care and outcomes for children with craniosynostosis born from January 1998 through December 2003. Mothers of 147 children were contacted and asked to complete a structured telephone interview; 82 mothers (55.8%) participated. Overall, the mean ages of children and their mothers at the time of interview were 4.4 and 34.8 years, respectively. Mothers interviewed tended to be white and, at a minimum, high school graduates. Most mothers reported being satisfied with the craniosynostosis-related information and support provided by medical care providers, and access to primary and specialty care was most often rated as satisfactory. Mothers tended to report the physical health of their child to be good; however, delays in cognitive and emotional development, hearing loss, and speech problems were identified. In addition, statistically significant differences among mothers in each state were noted for reports of the quality of team care, primary care, learning interventions, and perceived need for additional surgeries. These results suggest some limitations in craniosynostosis-related care and provide guidance to medical and surgical care providers in making need-based improvements in craniosynostosis surgery and care. Future studies are recommended to replicate this evaluation in additional populations.

Birth defects and military service since 1990.

The National Birth Defects Prevention Study (NBDPS) is an ongoing, multicenter, case-control study of over 30 major birth defects, and is one of the largest studies of the causes of birth defects to date. Data from it were examined to determine if maternal or paternal military service since 1990 as reported during the interview was associated with birth defects among offspring. Logistic regression was used to produce odds ratios (ORs) adjusted for major confounders. Overall, the results indicated no statistically significant association between parental military service since 1990 and increased risk of birth defects.

Trends in the postfortification prevalence of spina bifida and anencephaly in the United States.

BACKGROUND: The prevalence of NTDs in the US declined significantly after mandatory folic acid fortification; however, it is not known if the prevalence of NTDs has continued to decrease in recent years relative to the period immediately following the fortification mandate. METHODS: Population-based data from 21 birth defects surveillance systems were used to examine trends in the birth prevalence of spina bifida and anencephaly during 1999-2000, 2001-2002, and 2003-2004. Prevalence data were stratified by non-Hispanic White, non-Hispanic Black, and Hispanic race or ethnicity. Prevalence ratios were calculated by dividing the birth prevalences during the later time periods (2001-2002 and 2003-2004) by the birth prevalences during 1999-2000. RESULTS: During 1999-2004, 3,311 cases of spina bifida and 2,116 cases of anencephaly were reported. Hispanic infants had the highest prevalences of NTDs for all years. For all infants, the combined birth prevalences of spina bifida and anencephaly decreased 10% from the 1999-2000 period to the 2003-2004 period. The decline in spina bifida (3%) was not significant; however the decline in anencephaly (20%) was statistically significant. CONCLUSIONS: While the prevalences of spina bifida and anencephaly in the United States have declined since folic acid fortification in the food supply began, these data suggest that reductions in the prevalence of anencephaly continued during 2001-2004 and that racial and ethnic and other disparities remain.
