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.

The impact of prematurity and maternal socioeconomic status and education level on achievement-test scores up to 8th grade.

BACKGROUND: The relative influence of prematurity vs. maternal social factors (socioeconomic status and education level) on academic performance has rarely been examined. OBJECTIVE: To examine the impact of prematurity and maternal social factors on academic performance from 3rd through 8th grade. METHODS: We conducted a retrospective cohort study of infants born in 1998 at the University of Arkansas for Medical Sciences. The study sample included 58 extremely low gestational age newborns (ELGANs, 23‒<28 weeks), 171 preterm (≥28‒<34 weeks), 228 late preterm (≥34‒<37 weeks), and 967 term ((≥37‒<42 weeks) infants. Neonatal and maternal variables were collected including maternal insurance status (proxy measure for socioeconomic status) and education level. The primary outcomes were literacy and mathematics achievement-test scores from 3rd through 8th grade. Linear mixed models were used to identify significant predictors of academic performance. All two-way interactions between grade level, gestational-age (GA) groups, and social factors were tested for statistical significance. RESULTS: Prematurity, social factors, gender, race, gravidity, and Apgar score at one minute were critical determinants of academic performance. Favorable social factors were associated with a significant increase in both literacy and mathematic scores, while prematurity was associated with a significant decrease in mathematic scores. Examination of GA categories and social factors interaction suggested that the impact of social factors on test scores was similar for all GA groups. Furthermore, the impact of social factors varied from grade to grade for literacy, while the influence of either GA groups or social factors was constant across grades for mathematics. For example, an ELGAN with favorable social factors had a predicted literacy score 104.1 (P <.001), 98.2 (P <.001), and 76.4 (P <.01) points higher than an otherwise similar disadvantaged term infant at grades 3, 5, and 8, respectively. The difference in their predicted mathematic scores was 33.4 points for all grades (P <.05). CONCLUSION: While there were significant deficits in academic performance for ELGANs compared to PT, LPT, and term infants, the deficit could be offset by higher SES and better-educated mothers. These favorable social factors were critical to a child's academic achievement. The role of socioeconomic factors should be incorporated in discussions on outcome with families of preterm infants.

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.

Injured Children Receive Twice the Radiation Dose at Nonpediatric Trauma Centers Compared With Pediatric Trauma Centers.

BACKGROUND: Use of cranial CT scans in children has been increasing, in part due to increased awareness of sports-related concussions. CT is the largest contributor to medical radiation exposure, a risk factor for cancer. Long-term cancer risks of CT scans can be two to three times higher for children than for adults because children are more radiosensitive and have a longer lifetime in which to accumulate exposure from multiple scans. STUDY AIM: To compare the radiation exposure injured children receive when imaged at nonpediatric hospitals (NPHs) versus pediatric hospitals. METHODS: Injured children younger than 18 years who received a CT scan at a referring hospital during calendar years (CYs) 2010 and 2013 were included. Patient-level factors included demographics, mode of transportation, and Injury Severity Score, and hospital-level factors included region of state, radiology services, and hospital type and size. Our primary outcome of interest was the effective radiation dose. RESULTS: Four hundred eighty-seven children were transferred to the pediatric trauma center during CYs 2010 and 2013, with a median age of 7.2 years (interquartile range 5-13). The median effective radiation dose received at NPHs was twice that received at the pediatric trauma center (3.8 versus 1.6 mSv, P < .001). Results were confirmed in independent and paired analyses, after controlling for mode of transportation, emergency department disposition, level of injury severity, and at the NPH trauma center level, hospital type, size, region, and radiology services location. CONCLUSION: NPHs have the potential to substantially reduce the medical radiation received by injured children. Pediatric CT protocols should be considered.

Knowledge of Appropriate Outpatient Pediatric Echocardiogram Ordering in Primary Care Physicians and Trainees.

Appropriate Use Criteria (AUC) for the initial use of outpatient pediatric echocardiography were established to aid all clinicians in the evaluation of children with possible heart disease, and limit low diagnostic yield studies. We sought to (1) assess PCPs' and trainees' awareness of the AUC document; (2) compare their knowledge of appropriate echocardiogram ordering with that of pediatric cardiologists; and (3) identify additional medical and nonmedical factors affecting PCP echocardiogram ordering. An online survey with clinical scenarios derived from the AUC guidelines was distributed to PCPs and trainees in Arkansas, and pediatric cardiologists from Arkansas Children's Hospital and Cincinnati Children's Hospital Medical Center. Respondents were also asked to rate whether additional medical and nonmedical factors have "no," "mild," "moderate," or "major" impact on PCP echocardiogram ordering. Survey data were collected from 148 respondents. Awareness of the AUC was significantly lower in PCPs (21.4%) and trainees (14%) than in pediatric cardiologists (90.5%, p <0.001). For all rarely appropriate clinical scenarios, cardiologists had stronger agreement with the AUC document (90.9%) than did the PCP group (50.3%) and trainees (53.3%, p <0.001). The strongest additional factors affecting PCP echocardiogram ordering were parental anxiety, difficulty distinguishing innocent from pathologic murmurs, and legal implications of a missed diagnosis. In conclusion, PCPs and trainees are largely unaware of the existence of the pediatric echocardiogram AUC. Educational strategies to improve appropriate echocardiogram ordering should address not only increasing awareness of AUC, but also other factors affecting decision-making.

How often is congenital heart disease recognized as a significant comorbidity among hospitalized adults with congenital heart disease?

BACKGROUND: Despite frequent life-long hemodynamic and electrophysiologic abnormalities, adults with congenital heart defects (CHDs) are often lost to medical follow-up. Using a cohort of adults with CHD receiving hospital care in Arkansas, we sought to determine how often a CHD is recognized and coded during hospital admissions. METHODS: Data for this study come from the Agency for Healthcare Research and Quality's Arkansas State Inpatient Database (SID) for years 2004 to 2012. Using unique identifiers that link patients across hospitalizations, we created a cohort of 3973 patients≥18years old with an ICD-9 code for a CHD diagnosis noted at discharge during any hospitalization. RESULTS: These 3973 patients had 19,638 hospitalizations. A CHD was listed as the principal diagnosis in 3% of hospitalizations, a secondary diagnosis in 22%, and no CHD was listed in 75% of hospitalizations. Among patients with a critical CHD, no critical CHD was noted in 69% of hospitalizations. Cardiovascular events (heart failure, arrhythmias, cerebrovascular accidents, embolic event, or death) occurred in 60% of hospitalizations of critical CHD patients wherein no critical CHD was recorded. CONCLUSIONS: CHDs are rarely acknowledged during hospitalizations of adults with a known CHD even when cardiovascular events occur. Improved awareness, disclosure and attention to comorbid CHDs among patients and providers may improve hospital management and outcomes of cardiovascular events.

National In-Hospital Outcomes of Pregnancy in Women With Single Ventricle Congenital Heart Disease.

Most patients with single ventricle (SV) congenital heart disease are expected to survive to adulthood. Women with SV are often counseled against pregnancy; however, data on pregnancies in these women are lacking. We sought to evaluate in-hospital outcomes of pregnancy in women with SV. We used nationally representative data from the 1998 to 2012 National Inpatient Sample to identify women ≥18 years of age admitted to the hospital with International Classification of Diseases-9th Revision codes for an intrauterine pregnancy and a diagnosis of hypoplastic left heart syndrome, tricuspid atresia, or common ventricle. A matched comparison group without a diagnosis of congenital heart disease or pulmonary hypertension was identified from the database. National estimates of hospitalizations were calculated. Length of stay, hospital charges, and complications were analyzed and compared between groups. Charge data were adjusted to 2012 dollars. There were 282 admissions of pregnant women with SV (69% with deliveries) and 1,405 admissions in the control group (88% with deliveries). Vaginal delivery was more common in SV (74% vs 71%, p <0.001). Length of stay (4.1 ± 0.91 vs 2.8 ± 0.18 days, p <0.001) and charges ($30,787 ± 8,109 vs $15,536 ± 1,006, p <0.0001) were higher in the SV group. Complications occurred in most SV admissions and were more common in the SV group than in the control group. No deaths occurred. Cardiovascular complications occurred in 25% of pregnancy-related hospitalizations, although in-hospital pregnancy-related death is rare. Vaginal delivery is common in these patients. These data suggest that pregnancy and vaginal delivery can be tolerated in women with SV, although the risk for a cardiovascular event is significantly higher than in the general population.

The Clinical Impact of a Web-Based Image Repository on Radiation Exposure in Injured Children.

PURPOSE: The long-term cancer risks for children exposed to radiologic images can be two to three times higher than for adults because children are more sensitive to radiation and have a longer lifetime in which to accumulate exposure from CT scans. Injured children often undergo repeat CT imaging if they are transferred from non-pediatric hospitals to a Level I pediatric trauma center (PTC). This study determined the impact of a statewide web-based image repository (WBIR) on repeat imaging among transferred injured children. METHODS: All injured children who underwent CT imaging and were transferred to the PTC in 2010 (pre-WBIR) and 2013 (post-WBIR) were included. Patient-level factors studied included demographics, body region of scan, Injury Severity Score, and Emergency Department (ED) disposition. Change from pre to post on rate of repeat imaging was assessed. RESULTS: Two hundred fifty-four and 233 children, with a median age of 7.3 years, were transferred to the Children's Hospital in 2010 and 2013, respectively. Repeat imaging levels at the PTC were lower post-WBIR than pre-WBIR (20% versus 33%, odds ratio [OR] 0.54, P = .005). Images of the head decreased most significantly (60% versus 33%, OR 0.33). Images performed at Level II and III trauma centers were repeated less often after WBIR. CONCLUSIONS: The WBIR significantly reduced repeat imaging among injured children transferred to a PTC, especially children transferred from Level II and Level III trauma centers, children with lower-acuity injuries, and children with initial scans of the head. Radiation savings are expected to be beneficial to children.

The National Children's Study: Recruitment Outcomes Using the Provider-Based Recruitment Approach.

OBJECTIVE: In 2009, the National Children's Study (NCS) Vanguard Study tested the feasibility of household-based recruitment and participant enrollment using a birth-rate probability sample. In 2010, the NCS Program Office launched 3 additional recruitment approaches. We tested whether provider-based recruitment could improve recruitment outcomes compared with household-based recruitment. METHODS: The NCS aimed to recruit 18- to 49-year-old women who were pregnant or at risk for becoming pregnant who lived in designated geographic segments within primary sampling units, generally counties. Using provider-based recruitment, 10 study centers engaged providers to enroll eligible participants at their practice. Recruitment models used different levels of provider engagement (full, intermediate, information-only). RESULTS: The percentage of eligible women per county ranged from 1.5% to 57.3%. Across the centers, 3371 potential participants were approached for screening, 3459 (92%) were screened and 1479 were eligible (43%). Of those 1181 (80.0%) gave consent and 1008 (94%) were retained until delivery. Recruited participants were generally representative of the county population. CONCLUSIONS: Provider-based recruitment was successful in recruiting NCS participants. Challenges included time-intensity of engaging the clinical practices, differential willingness of providers to participate, and necessary reliance on providers for participant identification. The vast majority of practices cooperated to some degree. Recruitment from obstetric practices is an effective means of obtaining a representative sample.

Risk Factors for Increased Hospital Resource Utilization and In-Hospital Mortality in Adults With Single Ventricle Congenital Heart Disease.

Most patients with single ventricle congenital heart disease are now expected to survive to adulthood. Co-morbid medical conditions (CMCs) are common. We sought to identify risk factors for increased hospital resource utilization and in-hospital mortality in adults with single ventricle. We analyzed data from the 2001 to 2011 Nationwide Inpatient Sample database in patients aged ≥18 years admitted to nonteaching general hospitals (NTGHs), TGHs, and pediatric hospitals (PHs) with either hypoplastic left heart syndrome, tricuspid atresia or common ventricle. National estimates of hospitalizations were calculated. Elixhauser CMCs were identified. Length of stay (LOS), total hospital costs, and effect of CMCs were determined. Age was greater in NTGH (41.5 ± 1.3 years) than in TGH (32.8 ± 0.5) and PH (25.0 ± 0.6; p <0.0001). Adjusted LOS was shorter in NTGH (5.6 days) than in PH (9.7 days; p <0.0001). Adjusted costs were higher in PH ($56,671) than in TGH ($31,934) and NTGH ($18,255; p <0.0001). CMCs are associated with increased LOS (p <0.0001) and costs (p <0.0001). Risk factors for in-hospital mortality included increasing age (odds ratio [OR] 5.250, CI 2.825 to 9.758 for 45- to 64-year old vs 18- to 30-year old), male gender (OR 2.72, CI 1.804 to 4.103]), and the presence of CMC (OR 4.55, CI 2.193 to 9.436) for 2 vs none). No differences in mortality were found among NTGH, TGH, and PH. Cardiovascular procedures were more common in PH hospitalizations and were associated with higher costs and LOS. CMCs increase costs and mortality. In-hospital mortality is increased with age, male gender, and the presence of hypoplastic left heart syndrome.

Novel Educational Module for Subclavian Central Venous Catheter Insertion Using Real-Time Ultrasound Guidance.

OBJECTIVE: Given increasing evidence supporting a real-time ultrasound (US)-guided approach for subclavian vein (SCV) central venous catheter (CVC) insertion as compared with the traditional landmark approach, we sought to develop a standardized curriculum to offer healthcare providers a means to attain increased competency and confidence in US-guided SCV CVC insertion. DESIGN: Retrospective review of prospectively collected data. SETTING: Single institution's American College of Surgeons Level 1 Accredited Education Institute within an academic tertiary care center. SUBJECTS: A total of 77 residents and midlevel providers working in our surgical intensive care unit. INTERVENTIONS: Providers participated in a tiered educational module designed to teach safe US-guided SCV CVC insertion. The education consisted of a multimedia didactic presentation and a hands-on simulation session, including US anatomy on live subjects and anatomical model-based SCV CVC insertion. MEASUREMENTS AND MAIN RESULTS: Assessment of the effect of education included a written examination and confidence survey, administered pre- and postintervention, and videotaped simulation session graded by blinded expert evaluators. Of the 77 participants, 70 participants completed a posttest with a median 5-point increase in score compared with that of the pretest score (p < 0.0001). Confidence ratings based on a 5-point Likert scale demonstrated an increase in confidence in SCV CVC insertion (p < 0.0001), using the landmark approach (p < 0.0001), using US-guided approach (p < 0.0001), and in use of US to image the SCV (p < 0.0001). Postgraduate year-1 residents had lower mean global rating score (p = 0.010) than any other participants. CONCLUSIONS: This comprehensive hands-on teaching module-based curriculum enhanced learner knowledge of and confidence in US-guided SCV CVC insertion. This module can be implemented in simulation centers for teaching safe and successful SCV CVC insertion.

Lessons from Prenatal Care Provider-Based Recruitment into the National Children's Study.

In response to recruitment difficulties experienced by the National Children's Study, alternatives to the door-to-door recruitment method were pilot tested. This report describes outcomes, successes, and challenges of recruiting women through prenatal care providers in Benton County, Arkansas, USA. Eligible women residing in 14 randomly selected geographic segments were recruited. Data were collected during pregnancy, at birth, and at 3, 6, 9, 12, 18, and 24 months postpartum. Participants were compared to non-enrolled eligible women through birth records. Of 6402 attempts to screen for address eligibility, 468 patients were potentially eligible. Of 221 eligible women approached to participate, 151 (68%) enrolled in the 21-year study. Enrolled women were similar to non-enrolled women in age, marital status, number of prenatal care visits, and gestational age and birth weight of the newborn. Women enrolled from public clinics were more likely to be Hispanic, lower educated, younger and unmarried than those enrolled from private clinics. Sampling geographic areas from historical birth records failed to produce expected equivalent number of births across segments. Enrollment of pregnant women from prenatal care providers was successful.

Comparison of in-hospital and longer-term outcomes of hybrid and Norwood stage 1 palliation of hypoplastic left heart syndrome.

OBJECTIVES: The hybrid approach for the initial management of hypoplastic left heart syndrome shifts the risks of major open surgery from the vulnerable neonatal period to an older age. This study determined differences between the hybrid and the standard Norwood procedures in postoperative in-hospital mortality, renal failure, and survival to at least 2 years of age. METHODS: Data from the Pediatric Health Information System, a detailed hospital discharge database of 43 freestanding children's hospitals, were analyzed. The Pediatric Health Information System includes demographic information, diagnosis, and procedure and clinical service data. Instrumental variable regression techniques were used to estimate the predicted probability of in-hospital mortality, renal failure, and survival to 24 months of age for infants with hypoplastic left heart syndrome who received a hybrid or Norwood procedure. The statistical models controlled for demographics and comorbid chromosomal anomalies. RESULTS: A total of 3654 infants with hypoplastic left heart syndrome underwent intervention from 1998 to 2012. Of these, 242 underwent the hybrid approach and the remainder underwent the Norwood procedure. Instrumental variable models showed significantly reduced odds of patients who underwent the hybrid approach being diagnosed with renal failure (adjusted risk ratio [ARR], 0.48; 95% confidence interval [CI], 0.26-0.89); increased odds of surviving initial hospitalization (ARR, 1.28; 95% CI, 1.06-1.55); increased odds of survival, indicated by readmissions more than 6 months after initial hospitalization (ARR, 1.53; 95% CI, 1.05-2.22); and a decrease in length of stay by 20 days for the initial surgical hospitalization (95% CI, -27.4 to -13.9). CONCLUSIONS: The short term hospital-based outcomes and longer-term survival outcomes of the hybrid approach for hypoplastic left heart syndrome may be better than those of the Norwood procedure.

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.

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.

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.

Maltreatment-Related Emergency Department Visits Among Children 0 to 3 Years Old in the United States.

The emergency department (ED) is a vital entry point in the health care system for children who experience maltreatment. This study fills a gap in the maltreatment literature by presenting systematic, national estimates of maltreatment-related ED visits in the United States by children ≤3 years old, from 2006 to 2011, using the Nationwide Emergency Department Sample (NEDS). Children who experienced and likely experienced maltreatment were identified via International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes. Maltreatment was classified as physical or sexual abuse, neglect, or poly-victimization. The clinical and demographic profiles of children who experienced maltreatment were described. Approximately 10,095 children who experienced maltreatment (0.1% of total ED visits) and 129,807 children who likely experienced maltreatment (1.2% of total ED visits) were documented each year. Maltreatment was associated with significantly greater risk of injury, hospitalization, and death in the ED setting. Physical abuse was the most common explicit maltreatment diagnosis (33 ED visits per 100,000 children ≤3 years old) and neglect was the most common likely maltreatment diagnosis (436 ED visits per 100,000 children ≤3 years old). This study established the NEDS as a valuable complement to existing surveillance efforts of child maltreatment from a public health perspective.
