Transcutaneous bilirubinometry was originally developed as a potential replacement for invasive blood sampling, but its clinical application is still limited to a screening method for hyperbilirubinemia. Reasons for this limited clinical value may be diverse.

This study provides insight into the reasons for the limited clinical value of transcutaneous bilirubinometry. This aids to both better interpretation of the measured TcB value from a patient and to possible improvement of the clinical value of the technique. (Read the full article)

Tenfold medication error is a well-recognized risk of pharmacotherapy in pediatric practice but little evidence describes the circumstances of such errors.

This study identified 252 tenfold medication errors, 22 of which resulted in patient harm. We identified opioids and other high-risk medications to be associated with tenfold medication error and frequent, recurrent causes, mechanisms, and error enablers that suggest areas for future improvements.

Trisomy 13 and trisomy 18, common chromosomal abnormalities, are generally considered fatal within the first year after birth, although some children live longer. Little is known, however, about the inpatient medical courses of these infants and children.

Evaluation of nationally representative hospitalization data demonstrates that a significant number of children with trisomy 13 and trisomy 18 live beyond 1 year of age and that the care they receive includes both medical and surgical treatments. (Read the full article)

The presumed causes of neonatal deaths globally have remained unchanged over the past decade and include infections (~30%), prematurity (~30%), and asphyxia (~25%). Great uncertainty surrounds these estimates and, in addition, cases are likely misclassified as stillbirths.

These observational findings indicate that asphyxia accounts for a much higher percentage (60% of early deaths). Prematurity (18%), low birth weight (8%), and overt infection are much less common. The 5-minute Apgar score is an unreliable indicator of birth asphyxia. (Read the full article)

Rural Alaska children have high rates of hospitalization with lower respiratory tract infections from a variety of pathogens. Past studies of risk factors for respiratory syncytial virus infection associated medically high-risk status, household crowding, and infant feeding practices with hospitalization.

This study reveals the importance of medically high-risk status and infant feeding practices as important factors in respiratory hospitalization. In addition, we identified woodstove use and the absence of 2 or more sinks in household as risk factors for hospitalization. (Read the full article)

Cross-sectional studies have demonstrated associations between the white matter injury and cognitive impairment in very preterm born children. Longitudinal studies confirmed the relationships between cerebral MRI at term and neurodevelopmental outcomes at up to 2 years old.

White matter injury (but not gray matter injury) on term MRI predicted cognitive impairments of very preterm born infants at 9 years old. Qualitative assessment of white matter signal intensities showed limited predictive values of cognitive impairments. (Read the full article)

Disparities in outcomes of ethnic minority children have been reported, and have been ascribed to having barriers to access to health care. Minority parents have indicated that difficulties in access are because of problems with transportation and being non-English speaking.

This population-based study of Texas infants with severe congenital heart disease reports that neither home distance from a cardiac center nor Hispanic children having a Latin American–born parent were risk factors for first-year mortality. (Read the full article)

Primary care settings provide an important venue for early detection of substance use and intervention, but adolescent screening rates need improvement. Screening and brief interventions appear effective in reducing adult problem drinking but evidence for effectiveness among adolescents is needed.

A computer-facilitated system for screening, feedback, and provider brief advice for primary care can increase adolescent receipt of substance use screening across a variety of practice settings, and shows promise for reducing adolescents’ use of alcohol and cannabis. (Read the full article)

Most mothers in the United States do not meet recommendations for exclusive breastfeeding; however, little is known about how long mothers intend to exclusively breastfeed or how hospital practices affect achieving these intentions.

Most mothers who want to exclusively breastfeed intend to do so for ≥3 months, but the majority are not meeting their intended duration. Mothers are more likely to achieve their intended duration when their infant is not supplemented in the hospital. (Read the full article)

Parents are increasingly following alternative immunization schedules. Current studies suggest up to 21% of parents in the United States are intentionally delaying or refusing some or all of the recommended early-childhood vaccines.

This is the first study to use Immunization Information System data to quantify the proportion of children consistently delaying receipt of vaccines. Consistent-limiting children were found to have lower levels of recommended vaccines. (Read the full article)

There is no literature on the concentrations of vitamin B₆ vitamers in cerebrospinal fluid of preterm and term newborn infants. This knowledge, however, is highly important, because vitamin B₆ plays a pivotal role in brain development and functioning.

In cerebrospinal fluid of newborn infants, B₆ vitamer concentrations are strongly dependent on postmenstrual age, indicating that vitamin B₆ homeostasis in brain differs between preterm and term newborns. This has implications for the evaluation of epilepsy and vitamin B₆ deficiency. (Read the full article)

Adherence to Pediatric Advanced Life Support resuscitation guidelines for children with sepsis is low; however, few studies have been conducted in the tertiary care emergency department setting.

Adherence to septic shock guidelines in a tertiary care pediatric emergency department is low. Adherence to fluid guidelines and the entire PALS algorithm was associated with a shorter hospital length of stay. (Read the full article)

Data suggest that delivery at high-volume, high-technology hospitals reduces neonatal mortality. No study has examined other complications or compared the effects in multiple states by using a study design to control for unmeasured differences in case mix.

The survival benefit to delivering at a high-level NICU between 1995 and 2005 is larger than previously reported and varies between states. The survival benefits affect both extremely and moderately preterm infants. Complication rates were similar between hospital types. (Read the full article)

Although the impact of changes in the economy on child physical abuse rates is not well understood, there is concern that increased numbers of children may have been victims of physical abuse as a result of the recent economic recession.

Results of this study demonstrate that the rate of admissions for physical abuse to pediatric hospitals has increased during the past 10 years and suggest an association between that increase and the housing mortgage crisis. (Read the full article)

Because most childhood tuberculosis cases are sputum smear-negative, diagnosis relies largely upon clinical presentation, tuberculin skin testing, and chest radiograph. Diagnostic limitations contribute to treatment delays and high mortality. However, childhood tuberculosis (TB) mortality risk factors are not well documented.

This study demonstrates that false-negative TST is common in children with active TB and is associated with increased risk of death. A negative TST should not delay anti-TB therapy. Improved diagnostic modalities are urgently needed in resource-limited settings. (Read the full article)

Vitamin D is essential for bone health and for cardiovascular and immune function. In critically ill adults, vitamin D deficiency is common and associated with sepsis and with higher critical illness severity. The influence on pediatric critical illness is unclear.

We found a high prevalence of vitamin D deficiency in critically ill children, which was associated with higher critical illness severity. Vitamin D deficiency was less common in younger patients, in non-Hispanic white patients, in patients admitted over the summer, and in children taking supplemental vitamin D, with increasing amounts being more protective. (Read the full article)

Vitamin D is a pleiotropic hormone important for proper functioning of multiple organs. Adult critical care studies have suggested vitamin D as a modifiable risk factor. No studies have investigated the prevalence, risk factors, or role in pediatric critical illness.

This study provides evidence that the majority of critically ill children have vitamin D deficiency at the time of PICU admission, and that lower levels are associated with hypocalcemia, catecholamine administration, significant fluid bolus requirements, and longer PICU admissions.

Cholestasis predisposes to the development of fat-soluble vitamin (FSV) deficiency. D-α tocopheryl polyethylene glycol-1000 succinate and coadministered FSVs are absorbed in spite of cholestasis.

Infants with biliary atresia with total bilirubin >2 mg/dL are at risk for fat-soluble vitamin (FSV) deficiency. A multivitamin preparation containing d-α tocopheryl polyethylene glycol-1000 succinate alone is not effective in treating biochemical FSV insufficiency in cholestatic infants.

A growing number of epidemiologic studies suggest that individuals with lower vitamin D levels are at higher risk of acute respiratory tract infection. Randomized controlled trials are needed to determine if vitamin D supplementation would decrease this risk.

In a randomized controlled trial of 247 Mongolian children with vitamin D deficiency in winter, with double-blinding and 99% follow-up, vitamin D supplementation significantly reduced the risk of acute respiratory tract infections. (Read the full article)

Forearm fractures are unique injuries which are associated with lower bone mineral density in adults and white children. The relationships among bone mineral density, 25-hydroxyvitamin D status, and risk for forearm fracture have not been investigated in African American children.

Our data support an association between both lower bone mineral density and vitamin D deficiency and increased odds of forearm fracture in African American children. Promotion of bone health is indicated in this population. (Read the full article)

Skills learned in standardized courses are estimated to last only a few months. Neonatal Resuscitation Program certification is mandatory for all pediatric residents and is valid for 2 years. Exact timing of when proficiency is lost is unknown.

Neonatal Resuscitation Program skills deteriorate immediately after certification, whereas knowledge is better retained. Significant skill deficits were seen at baseline raising concerns regarding the efficacy of the current course structure. Discrepancies in knowledge and skill retention may impact caregiver performance. (Read the full article)

Evaluation of neonatal surgical outcomes is necessary to guide improvements in the quality of care. Meaningful comparisons must adjust for factors that alter outcomes independent of the surgical procedures.

Herein is described a method that permits risk adjustment for the broad range of noncardiac neonatal surgery, regardless of gestational age, to permit useful comparisons for quality improvement. (Read the full article)

Although several studies have demonstrated increased morbidity and mortality with pH1N1 in children, others have found its clinical course to be similar to seasonal influenza. Moreover, most studies were conducted at single centers, thus raising concerns about generalizability of findings.

This analysis provides national-level active hospital-based surveillance data comparing pH1N1 with 5 previous years of seasonal influenza A and demonstrates differences in risk factors and clinical presentation but not in ICU admission or mortality. (Read the full article)

Risk of preterm birth (PTB) has been noted to be higher for newborns with congenital heart defects (CHDs). The role of associated anomalies, whether PTB is spontaneous or medically induced, or specific categories of CHDs have not been elucidated.

By using population-based data, we found that PTB associated with CHDs was due to spontaneous PTB. Associated anomalies accounted for a small part of this increase, and there were specific associations between categories of CHDs and PTB. (Read the full article)

Changes in resident work hours are believed to have an impact on resident education and patient safety.

This study provides an understanding of the impact of changes in resident work hours on the staffing strategies of children’s hospitals. (Read the full article)

Findings from 3 studies suggest that the diagnosis of venous thromboembolism in hospitalized US children has increased in recent years.

This study provides additional evidence of an increasing trend in the rate of venous thromboembolism-associated hospitalization in US children, as well as a concurrent increase in the prevalence of venous catheter procedures. (Read the full article)

Despite numerous preventive strategies including prophylaxis with 400 IU/day of vitamin D in recent years, the deficiency of vitamin D in infants is still a global health problem.

This study reveals that the risk of vitamin D deficiency is high in exclusively breastfed infants, especially in winter, despite vitamin D supplementation. Therefore, it is suggested that an adjustment of vitamin D dosage for seasonal variation might be necessary. (Read the full article)

Significant variation in congenital hypothyroidism screening operations/performance has been observed in the United States. The origin of this variation remains unknown, in part because of a lack of evaluation. Accordingly, debates persist about optimal screening operations including laboratory testing methods.

Four distinct screening protocols applied to Michigan resident infants are compared in detecting congenital hypothyroidism overall and specific to cases characterized by high initial thyrotropin concentrations thought to have a more severe form of the disease. (Read the full article)

Clinical guidelines for the evaluation of suspected physical abuse in young children emphasize performing radiologic imaging to screen for occult fractures. Little is known about the degree of adherence to guidelines for screening for occult fractures among pediatric hospitals.

Adherence to guidelines related to screening for occult fractures in young children diagnosed with physical abuse varies significantly among pediatric hospitals. Use of screening in infants who have injuries associated with a high likelihood of abuse also varies among pediatric hospitals. (Read the full article)

The false-positive rate of newborn screening for classic congenital adrenal hyperplasia (CAH) remains high and has not been significantly improved by adjusting 17α-hydroxyprogesterone cutoff values for birth weight and/or gestational age. In response, 4 states have initiated second-tier steroid profile screening.

Under second-tier screening, the false-positive rate remains high, and classic CAH cases missed by screening (false-negatives) occur more frequently than reported. Physicians are cautioned that a negative screen does not necessarily rule out CAH. (Read the full article)

There are limited data on current testing and treatment patterns for children hospitalized with pneumonia, and on whether institutional guidelines affect care.

The use of institutional clinical practice guidelines was not associated with changes in diagnostic testing, hospital length of stay, or costs for children hospitalized with pneumonia, but was associated with increased use of narrow-spectrum antibiotics. (Read the full article)

The rising burden of allergy is most evident in infancy, indicating the importance of early exposures. Reduced vitamin D status in pregnancy has been associated with atopy and respiratory outcomes, but there is less information on other early allergic outcomes.

Cord blood 25-hydroxyvitamin D₃ concentrations <50 nmol/L were highly prevalent in an Australian population. Lower vitamin D levels were associated with increased risk of eczema at 12 months of age, whereas there was no association with sensitization or food allergy. (Read the full article)

Heart rate continues to be the single most important indicator of well-being in a newborn. Availability of a reliable method to determine heart rate in the first minute would help determine resuscitation interventions, particularly for the extremely premature infant.

Electrocardiograms can provide a reliable, continuous heart rate in the most premature infants in the first minute of resuscitation compared with pulse oximeters. (Read the full article)

Patients living in rural versus urban counties encounter different health care environments. Whether these differences result in different health care utilization for rural versus urban infants is not known.

In this study, infants living in rural California counties were hospitalized less often than infants living in urban counties. Among those hospitalized, infants living in rural counties were hospitalized for fewer cumulative days than infants residing in urban counties. (Read the full article)

Hypothalamic-pituitary-adrenal axis suppression caused by inhaled corticosteroids is considered rare. Adrenal crisis has been described in children treated with high doses of inhaled fluticasone propionate. It was recommended that doses licensed for children should not be exceeded.

Biochemically confirmed hypothalamic-pituitary-adrenal axis dysfunction may occur in two-thirds of children treated with corticosteroids. Suppression may occur at low doses and especially with concomitant nasal steroids. Children with poor adherence or obesity may be less prone to adrenal crisis. (Read the full article)

Pediatric tuberculosis is significant for public health professionals because it is an indicator of the recent transmission of tuberculosis in the community. Data on incidence and clinical features of pediatric tuberculosis from China are scarce.

We conducted this study to describe the patient characteristics, clinical–epidemiological profile, and treatment outcomes for pediatric tuberculosis in a referral hospital setting in China. (Read the full article)

National asthma treatment guidelines include the recommendation that all asthma patients receive a written asthma action plan. No previous study has sought to examine the readability, suitability, and content of asthma action plans within a nationally representative sample.

Although variability was found across written asthma action plans, and improvements in readability, suitability, and content are needed, there were also many common elements that would support a move to a single universal standard action plan. (Read the full article)

There is widespread belief that many hospital readmissions in adults are avoidable by improvements in care and discharge planning processes, resulting in significant cost savings; however, current studies have not examined the preventability of such readmissions in children’s hospitals.

The overall rate of pediatric 15-day readmissions considered to be preventable was low, less than 2% of total hospital admissions. Pediatric readmissions are unlikely to serve as a highly productive focus for cost savings or quality measurement. (Read the full article)

The medical home likely plays a positive role in outpatient health outcomes. Asthma is a common and frequent reason for pediatric hospitalization. It is unknown whether having a quality medical home can prevent readmission in children hospitalized for asthma exacerbations.

Poor access to a medical home was associated with increased readmission for asthma, whereas other measured aspects of medical home were not. Children with private insurance and good access to care had the lowest rates of readmission within a year. (Read the full article)

Children with congenital heart disease (CHD) are at increased risk for poor growth. Several factors may play a role in poor growth, including feeding difficulties, increased caloric requirements, and the effects of cardiac lesions on growth regulation.

In children with CHD, impaired growth as measured by weight, length, and head circumference occurs simultaneously rather than sequentially, supporting the theory that altered growth regulation likely plays an important role in the poor growth of children with CHD. (Read the full article)

Outcomes analyses after trauma reveal long-term disability but are limited to specific injuries, older data, or all ages combined. There are no contemporary assessments of physical disability among children after inpatient rehabilitation for a wide range of traumatic injuries.

This is the first contemporary study to describe the physical disability of a large pediatric cohort after inpatient rehabilitation for various injuries. After a mean 21-day inpatient rehabilitation stay, significant reductions in functional disability were achieved across injury mechanisms. (Read the full article)

Cow’s milk consumption has opposite effects on vitamin D and iron levels in children; however, the amount of cow’s milk intake required for sufficient stores of vitamin D and iron is poorly understood, and existing guidelines on consumption are unclear.

Two cups of cow’s milk per day is sufficient to maintain healthy vitamin D and iron stores for most children. Wintertime vitamin D supplementation appears particularly important among children with darker skin pigmentation. (Read the full article)

Socioeconomic status (SES) is inversely related to mortality and health in children; the higher an individual’s SES, the less likely illness and death. It is unknown whether the association of SES and pediatric mortality exists in the inpatient setting.

Within children’s hospitals, in-hospital mortality is inversely associated with SES, but is lower than expected for even the lowest SES quartile. The association between SES and mortality varies by clinical service line. (Read the full article)

Because pediatric appendicitis is challenging to diagnose, computed tomography (CT) is used frequently. Childhood radiation exposure is associated with increased risk of cancer. Ultrasound avoids radiation exposure but is less sensitive for appendicitis than CT.

Controlling for referral bias, evaluation at a community compared with a children’s hospital is associated with higher CT and lower ultrasound use before appendectomy. CT and ultrasound accuracy for appendicitis in children varies with hospital type. (Read the full article)

Adequate vitamin D is essential for skeletal health in developing children. Although excess body weight is associated with risk of vitamin D deficiency, the national prevalence of vitamin D deficiency in overweight and obese children is unknown.

Vitamin D deficiency is highly prevalent in overweight and obese children, and severely obese and minority children are disproportionately affected. There are many modifiable factors associated with vitamin D deficiency in overweight and obese children. (Read the full article)

Previous studies suggest that hospitals under the greatest financial strain may be more prone to adverse events because they have limited resources to invest in quality and safety.

The patient population served, rather than hospital category, best predicts measured quality, underscoring the need for robust risk adjustment when incentivizing quality or comparing hospitals. Thus, problems of quality may not be systemic across hospital categories. (Read the full article)

A reduced nephron number is associated with glomerular hyperfiltration, resulting in renal injury such as hypertension, proteinuria, and chronic kidney disease. Patients with a solitary functioning kidney have an increased risk of dialysis in early adulthood.

This study demonstrates that a subset of children with a solitary functioning kidney progress toward renal injury during childhood. Risk factors for renal injury are ipsilateral anomalies of the kidney and urinary tract and small renal length. (Read the full article)

A small number of studies have found that the introduction of smoke-free legislation has been associated with a reduction in hospital admissions and emergency department visits for asthma.

The implementation of smoke-free legislation in England was associated with an immediate 8.9% reduction in hospitalizations for asthma along with a decrease of 3.4% per year. (Read the full article)

A number of studies have shown that home-visiting interventions can improve outcomes for children being raised in families that face multiple adversities. It is less clear how well these benefits are sustained over long periods.

The current study shows that the Early Start program of home visitation has benefits in terms of reducing child abuse, increasing parental competence, and improving childhood behavioral adjustment for up to 9 years, suggesting long-term benefits of home visitation. (Read the full article)

Rapid initiation of effective chest compressions (CCs) for patients in cardiac arrest improves outcomes, yet even trained rescuers fail to provide consistently effective CCs. Pediatric data on CC quality and objective measures of CC work are limited.

CC quality deteriorates similarly in pediatric and adult models, and overall work done to compress the pediatric chest is similar to that in adults. Power output during CC performance is analogous to that generated during intense exercise such as running. (Read the full article)
