Health-Related Quality of Life for Parents of Infants with Bronchopulmonary Dysplasia.

OBJECTIVE: To determine how bronchopulmonary dysplasia (BPD) affects health-related quality of life (HRQL) among infants from NICU hospitalization through 1-year postdischarge. STUDY DESIGN: This was a prospective cohort study of infants with BPD and their parents. Parent HRQL was measured with the PedsQL Family Impact Module before NICU discharge and 3- and 12-months post-discharge. At 12 months, parent-reported child health outcomes included questions from the Test of Respiratory and Asthma Control in Kids, Warner Initial Developmental Evaluation of Adaptive and Functional Skills, and National Survey of Children with Special Health Care Needs. HRQL change over time was assessed by multivariable linear regression. RESULTS: Of 145 dyads, 129 (89%) completed 3-month follow-up, and 113 (78%) completed 12-month follow-up. In the NICU, lower HRQL was associated with earlier gestational age, postnatal corticosteroids, outborn status, and gastrostomy tubes. At 3 months, lower HRQL was associated with readmissions and home oxygen use. At 12 months, lower HRQL was associated with parent-reported difficulty breathing, lower developmental scores, and not playing with other children. At 3 and 12 months, 81% of parents reported similar or improved HRQL compared with the NICU period. Parents reporting infant respiratory symptoms experienced less improvement. CONCLUSIONS: BPD affects parent HRQL over the first year. Most parents report similar or better HRQL after discharge compared with the NICU stay. Less improvement is reported by parents of infants experiencing respiratory symptoms at 12 months. Efforts to improve parent HRQL should target respiratory symptoms and social isolation.

Return visit rates after an emergency department discharge for children with sickle cell pain episodes.

BACKGROUND: High return visit rates after hospitalization for people with sickle cell disease (SCD) have been previously established. Due to a lack of multicenter emergency department (ED) return visit rate data, the return visit rate following ED discharge for pediatric SCD pain treatment is currently unknown. PROCEDURE: A seven-site retrospective cohort study of discharged ED visits for pain by children with SCD was conducted using the Pediatric Emergency Care Applied Research Network Registry. Visits between January 2017 and November 2021 were identified using previously validated criteria. The primary outcome was the 14-day return visit rate, with 3- and 7-day rates also calculated. Modified Poisson regression was used to analyze associations for age, sex, initial hospitalization rate, and a visit during the COVID-19 pandemic with return visit rates. RESULTS: Of 2548 eligible ED visits, approximately 52% were patients less than 12 years old, 50% were female, and over 95% were non-Hispanic Black. The overall 14-day return visit rate was 29.1% (95% confidence interval [CI]: 27.4%-30.9%; site range 22.7%-31.7%); the 7- and 3-day return visit rates were 23.0% (95% CI: 21.3%-24.6%) and 16.7% (95% CI: 15.3%-18.2%), respectively. Younger children had slightly lower 14-day return visit rates (27.3% vs. 31.1%); there were no associations for site hospitalization rate, sex, and a visit occurring during the pandemic with 14-day returns. CONCLUSION: Nearly 30% of ED discharged visits after SCD pain treatment had a return visit within 14 days. Increased efforts are needed to identify causes for high ED return visit rates and ensure optimal ED and post-ED care.

Safely reducing unnecessary benign breast biopsies by applying non-mass and DWI directional variance filters to ADC thresholding.

BACKGROUND: Thresholding apparent diffusion coefficient (ADC) maps obtained from Diffusion-Weighted-Imaging (DWI) has been proposed for identifying benign lesions that can safely avoid biopsy. The presence of malignancies with high ADC values leads to high thresholds, limiting numbers of avoidable biopsies. PURPOSE: We evaluate two previously reported methods for identifying avoidable biopsies: using case-set dependent ADC thresholds that assure 100% sensitivity and using negative likelihood ratio (LR-) with a fixed ADC threshold of 1.50 × 10-3 mm2/s. We evaluated improvements in efficacy obtained by excluding non-mass lesions and lesions with anisotropic intra-lesion morphologic characteristics. STUDY TYPE: Prospective. POPULATION: 55 adult females with dense breasts with 69 BI-RADS 4 or 5 lesions (38 malignant, 31 benign) identified on ultrasound and mammography and imaged with MRI prior to biopsy. FIELD STRENGTH/SEQUENCE: 1.5 T and 3.0 T. DWI. ASSESSMENT: Analysis of DWI, including directional images was done on an ROI basis. ROIs were drawn on DWI images acquired prior to biopsy, referencing all available images including DCE, and mean ADC was measured. Anisotropy was quantified via variation in ADC values in the lesion core across directional DWI images. STATISTICAL TESTS: Improvement in specificity at 100% sensitivity was evaluated with exact McNemar test with 1-sided p-value < 0.05 indicating statistical significance. RESULTS: Using ADC thresholding that assures 100% sensitivity, non-mass and directional variance filtering improved the percent of avoidable biopsies to 42% from baseline of 10% achieved with ADC thresholding alone. Using LR-, filtering improved outcome to 0.06 from baseline 0.25 with ADC thresholding alone. ADC thresholding showed a lower percentage of avoidable biopsies in our cohort than reported in prior studies. When ADC thresholding was supplemented with filtering, the percentage of avoidable biopsies exceeded those of prior studies. DATA CONCLUSION: Supplementing ADC thresholding with filters excluding non-mass lesions and lesions with anisotropic characteristics on DWI can result in an increased number of avoidable biopsies.

Prospective Risk Stratification Identifies Healthcare Utilization Associated with Home Oxygen Therapy for Infants with Bronchopulmonary Dysplasia.

OBJECTIVE: To test whether prospective classification of infants with bronchopulmonary dysplasia identifies lower-risk infants for discharge with home oxygen who have fewer rehospitalizations by 1 year after neonatal intensive care unit discharge. STUDY DESIGN: This is a prospective single-center cohort that included infants from 2016 to 2019 with bronchopulmonary dysplasia, defined as receiving respiratory support at 36 weeks of postmenstrual age. "Lower-risk" infants were receiving ≤2 L/min nasal cannula flow, did not have pulmonary hypertension or airway comorbidities, and had blood gas partial pressure of carbon dioxide <70 mm Hg. We compared 3 groups by discharge status: lower-risk room air, lower-risk home oxygen, and higher-risk home oxygen. The primary outcome was rehospitalization at 1 year postdischarge, and the secondary outcomes were determined by the chart review and parent questionnaire. RESULTS: Among 145 infants, 32 (22%) were lower-risk discharged in room air, 49 (32%) were lower-risk using home oxygen, and 64 (44%) were higher-risk. Lower-risk infants using home oxygen had rehospitalization rates similar to those of lower-risk infants on room air (18% vs 16%, P = .75) and lower rates than higher-risk infants (39%, P = .018). Lower-risk infants using home oxygen had more specialty visits (median 10, IQR 7-14 vs median 6, IQR 3-11, P = .028) than those on room air. Classification tree analysis identified risk status as significantly associated with rehospitalization, along with distance from home to hospital, inborn, parent-reported race, and siblings in the home. CONCLUSIONS: Prospectively identified lower-risk infants discharged with home oxygen had fewer rehospitalizations than higher-risk infants and used more specialty care than lower-risk infants discharged in room air.

Quality Improvement Project to Improve the Timeliness of Care for Children With Testicular Torsion in the Emergency Department.

Introduction: Testicular torsion (TT) is a urologic emergency that requires timely diagnosis and surgery. We noted variation in the door-to-detorsion times for patients with TT at our institution and our orchiectomy rate was 25.8%. We aimed to decrease the mean door-to-detorsion time from 124.6 to 114.6 minutes or less over 12 months. Methods: A multidisciplinary team of pediatric emergency medicine, radiology, urology physicians, and nurses, was formed. Our key drivers were use of Testicular Workup for Ischemia and Suspected Torsion (TWIST) score, prompt urology consultation, and efficient transfer from emergency department (ED) to operating room. Our process measures were TWIST score documentation rate and early urology consultation rate, outcome measures were door-to-detorsion time and orchiectomy rate, and balancing measure was ultrasound utilization rate. Early urology consultation occurred when the ED provider documented telephone communication with urology, immediately after placing a testicular doppler ultrasound (TDUS) order and before TDUS result. Results: Over 2 years, 45 cases of TT were diagnosed. TWIST score documentation was implemented and was sustained at 78%. This improved early urology consultations from 40% to 60%. The mean door-to-detorsion time improved from 124.6 to 114.2 minutes. There was no reduction in the orchiectomy rate or TDUS utilization rate. Conclusions: A quality improvement project to improve the timeliness of care for children with TT resulted in expedited ED care but did not impact the orchiectomy rate.

Correlates of sexually transmitted infection testing following women's release from jail.

Given incarcerated women's frequent transitions between jail and community, it is important to seize opportunities to provide comprehensive health care. A potential time to provide care might be when getting tested for sexually transmitted infections (STIs). Our objective was to determine the proportion of women receiving STI testing and correlates, following jail release. This secondary analysis was of one-year follow-up data from women who participated in a jail-based cervical health literacy intervention in three Kansas City jails from 2014 to 2016. Most (82%) completed the survey in the community. The analysis included 133 women. Mean age 35 years (19-58 years). Sixty-two percent obtained STI testing within one-year post-intervention. Using logistic regression this was associated with younger age (odds ratio [OR] = 0.87; 95% confidence interval [CI] 0.80, 0.95), receiving high school education (OR = 4.33; 95% CI 1.00, 18.74), having insurance (OR = 4.32; 95% CI 1.25, 14.89), no illicit drug use (OR = 0.09; 95% CI 0.01, 0.81), and no drinking problem (OR = 0.04; 95% CI 0.00, 0.45). In this study, many women sought STI testing following jail release. Clinicians/public health practitioners may find it useful to engage these high-risk women in broader women's health services seeking STI testing.

The association between timely opioid administration and hospitalization in children with sickle cell disease presenting to the emergency department in acute pain.

INTRODUCTION: The National Heart, Lung, and Blood Institute guidelines for sickle cell disease (SCD) pain crisis management recommend opioids within 60 minutes of emergency department (ED) registration and every 30 minutes thereafter until acute pain is managed. These guidelines are based on expert opinion without published, supporting data. OBJECTIVE: To evaluate the association between timely ED opioid administration and hospitalization rates in children with SCD. METHODS: Retrospective cohort of children presenting to a children's hospital ED with SCD pain between January 1, 2014, and April 30, 2018. Visits were extracted using ICD codes, chief complaints, and receipt of at least one opioid, and then reviewed to confirm the visit was an uncomplicated pain crisis. The primary outcome was hospitalization, yes or no. Generalized estimating equations were used to determine adjusted odds of hospitalization for the timely administration of initial and second doses of opioids. RESULTS: Of the 902 eligible visits, 368 (40.8%) resulted in hospitalization. The mean (SD) age was 11.9 (± 5.2) years. The first opioid was administered within 60 minutes of arrival in 601 (66.6%) visits. The second opioid was administered within 30 minutes of the first in 84 (12.3%) visits. Receipt of the first opioid within 60 minutes of arrival was not associated with decreased hospitalization (1.30 [0.96-1.76]). However, receipt of the second dose within 30 minutes of the first was associated with decreased hospitalization (0.56 [0.33-0.94]). CONCLUSION: This study suggests an association between children with SCD receiving a second dose within 30 minutes of the first opioid dose and decreased hospitalizations.

Discrimination of benign from malignant breast lesions in dense breasts with model-based analysis of regions-of-interest using directional diffusion-weighted images.

BACKGROUND: There is an increasing interest in non-contrast-enhanced magnetic resonance imaging (MRI) for detecting and evaluating breast lesions. We present a methodology utilizing lesion core and periphery region of interest (ROI) features derived from directional diffusion-weighted imaging (DWI) data to evaluate performance in discriminating benign from malignant lesions in dense breasts. METHODS: We accrued 55 dense-breast cases with 69 lesions (31 benign; 38 cancer) at a single institution in a prospective study; cases with ROIs exceeding 7.50 cm2 were excluded, resulting in analysis of 50 cases with 63 lesions (29 benign, 34 cancers). Spin-echo echo-planar imaging DWI was acquired at 1.5 T and 3 T. Data from three diffusion encoding gradient directions were exported and processed independently. Lesion ROIs were hand-drawn on DWI images by two radiologists. A region growing algorithm generated 3D lesion models on augmented apparent-diffusion coefficient (ADC) maps and defined lesion core and lesion periphery sub-ROIs. A lesion-core and a lesion-periphery feature were defined and combined into an overall classifier whose performance was compared to that of mean ADC using receiver operating characteristic (ROC) analysis. Inter-observer variability in ROI definition was measured using Dice Similarity Coefficient (DSC). RESULTS: The region-growing algorithm for 3D lesion model generation improved inter-observer variability over hand drawn ROIs (DSC: 0.66 vs 0.56 (p < 0.001) with substantial agreement (DSC > 0.8) in 46% vs 13% of cases, respectively (p < 0.001)). The overall classifier improved discrimination over mean ADC, (ROC- area under the curve (AUC): 0.85 vs 0.75 and 0.83 vs 0.74 respectively for the two readers). CONCLUSIONS: A classifier generated from directional DWI information using lesion core and lesion periphery information separately can improve lesion discrimination in dense breasts over mean ADC and should be considered for inclusion in computer-aided diagnosis algorithms. Our model-based ROIs could facilitate standardization of breast MRI computer-aided diagnostics (CADx).

Home Oxygen Use and 1-Year Readmission among Infants Born Preterm with Bronchopulmonary Dysplasia Discharged from Children's Hospital Neonatal Intensive Care Units.

OBJECTIVE: To determine associations between home oxygen use and 1-year readmissions for preterm infants with bronchopulmonary dysplasia (BPD) discharged from regional neonatal intensive care units. STUDY DESIGN: We performed a secondary analysis of the Children's Hospitals Neonatal Database, with readmission data via the Pediatric Hospital Information System and demographics using ZIP-code-linked census data. We included infants born <32 weeks of gestation with BPD, excluding those with anomalies and tracheostomies. Our primary outcome was readmission by 1 year corrected age; secondary outcomes included readmission duration, mortality, and readmission diagnosis-related group codes. A staged multivariable logistic regression was adjusted for center, clinical, and social risk factors; at each stage we included variables associated at P < .1 in bivariable analysis with home oxygen use or readmission. RESULTS: Home oxygen was used in 1906 of 3574 infants (53%) in 22 neonatal intensive care units. Readmission occurred in 34%. Earlier gestational age, male sex, gastrostomy tube, surgical necrotizing enterocolitis, lower median income, nonprivate insurance, and shorter hospital-to-home distance were associated with readmission. Home oxygen was not associated with odds of readmission (OR, 1.2; 95% CI, 0.98-1.56), readmission duration, or mortality. Readmissions for infants with home oxygen were more often coded as BPD (16% vs 4%); readmissions for infants on room air were more often gastrointestinal (29% vs 22%; P < .001). Clinical risk factors explained 72% of center variance in readmission. CONCLUSIONS: Home oxygen use is not associated with readmission for infants with BPD in regional neonatal intensive care units. Center variation in home oxygen use does not impact readmission risk. Nonrespiratory problems are important contributors to readmission risk for infants with BPD.

Can PROMIS domains of pain and physical functioning detect changes in health over time for children with sickle cell disease?

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) includes multiple domains that measure pain and physical functioning which are valid and reliable for use in children with sickle cell disease. The responsiveness of these measures to detect changes in health status over time among children with sickle cell disease is unknown. PROCEDURE: We conducted a prospective cohort study of children presenting to emergency department (ED) with vaso-occlusive crises. Children completed PROMIS surveys in the ED and at two follow-up time points (7-10 days and 1-3 months) after their acute care visit. Linear mixed models were used to determine if there were significant changes in PROMIS T scores over time. We used a patient's global assessment of change in pain question to anchor the changes in PROMIS scores (mean and 95% confidence interval). A change was considered statistically significant if the 95% CI did not include 0. RESULTS: We found that patients improved significantly in all domains 1 to 3 months after discharge from an acute care visit for pain. In addition, the pain and physical stress experience domains were responsive to change 7 to 10 days after discharge. Using the anchor of change in pain, for children who had considerable improvement in pain, there were significant changes in PROMIS T scores ranging from 6 to 15. CONCLUSIONS: Relevant PROMIS domains detect changes in children experiencing acute vaso-occlusive crises. These domains can be used in research and clinic settings to measure clinically relevant change in children with sickle cell disease.

Parent Preferences Regarding Home Oxygen Use for Infants with Bronchopulmonary Dysplasia.

OBJECTIVES: To determine parent preferences for discharge with home oxygen in infants with bronchopulmonary dysplasia. STUDY DESIGN: This was a prospective study of parents of infants born at <32 weeks' gestation with established bronchopulmonary dysplasia and approaching neonatal intensive care unit (NICU) discharge. Parents were presented a hypothetical scenario of an infant who failed weaning to room air and 2 options: discharge with home oxygen or try longer to wean oxygen. The initial scenario risks reflected a 1.5-week difference in NICU length of stay and no differences in other outcomes. Length of stay and readmission outcomes were increased or decreased until the parent switched preference. Three months after discharge, parents were asked to reconsider their preference. Differences were analyzed by χ2 or Kruskal-Wallis tests. RESULTS: Of 125 parents, 50% preferred home oxygen. For parents preferring home oxygen, the most important reason was comfort at home (79%). Forty percent switched preference when the length of stay difference decreased by 1 week; 35% switched when readmission increased by 5%. For parents preferring to stay in NICU, the most important reason was fear of taking care of the child at home (73%). Thirty-two percent switched preference when the length of stay difference increased by 1 week; 31% switched when readmission decreased by 5%. One hundred ten parents completed the 3-month follow-up; 80 were discharged with home oxygen. Seventy-eight percent would prefer home oxygen (97% who initially preferred home oxygen and 60% who initially preferred to stay in the NICU). CONCLUSIONS: Parents weigh differences in NICU length of stay and readmission risk similarly. After discharge, most prefer earlier discharge with home oxygen. Earlier education to increase comfort with home technology may facilitate NICU discharge planning.

Consensus-based Criterion Standard for the Identification of Pediatric Patients Who Need Emergency Medical Services Transport to a Hospital with Higher-level Pediatric Resources.

BACKGROUND: Emergency medical services (EMS) providers must be able to identify the most appropriate destination facility when treating children with potentially severe medical illnesses. Currently, no validated tool exists to assist EMS providers in identifying children who need transport to a hospital with higher-level pediatric care. For such a tool to be developed, a criterion standard needs to be defined that identifies children who received higher-level pediatric medical care. OBJECTIVE: The objective was to develop a consensus-based criterion standard for children with a medical complaint who need a hospital with higher-level pediatric resources. METHODS: Eleven local and national experts in EMS, emergency medicine (EM), and pediatric EM were recruited. Initial discussions identified themes for potential criteria. These themes were used to develop specific criteria that were included in a modified Delphi survey, which was electronically delivered. The criteria were refined iteratively based on participant responses. To be included, a criterion required at least 80% agreement among participants. If an item had less than 50% agreement, it was removed. A criterion with 50% to 79% agreement was modified based on participant suggestions and included on the next survey, along with any new suggested criteria. Voting continued until no new criteria were suggested and all criteria received at least 80% agreement. RESULTS: All 11 recruited experts participated in all seven voting rounds. After the seventh vote, there was agreement on each item and no new criteria were suggested. The recommended criterion standard included 13 items that apply to patients 14 years old or younger. They included IV antibiotics for suspicion of sepsis or a seizure treated with two different classes of anticonvulsive medications within 2 hours, airway management, blood product administration, cardiopulmonary resuscitation, electrical therapy, administration of specific IV/IO drugs or respiratory assistance within 4 hours, interventional radiology or surgery within 6 hours, intensive care unit admission, specific comorbid conditions with two or more abnormal vital signs, and technology-assisted children seen for device malfunction. CONCLUSION: We developed a 13-item consensus-based criterion standard definition for identifying children with medical complaints who need the resources of a hospital equipped to provide higher-level pediatric services. This criterion standard will allow us to create a tool to improve pediatric patient care by assisting EMS providers in identifying the most appropriate destination facility for ill children.

Parents' pain medication underdosing is associated with more emergency department visits in sickle cell disease.

OBJECTIVE: To determine the association between health literacy, medication knowledge, and pain treatment skills with emergency department (ED) use of parents of children with sickle cell disease (SCD). METHODS: Parents of children 1- to 12-years-old with SCD were enrolled. Health literacy was assessed using the Newest Vital Sign. Parents completed a structured interview assessing knowledge of the dosage and frequency of home pain medications and an applied skills task requiring them to dose a prescribed pain medication. Underdosage was defined by too small a dose (dosage error) or too infrequent a dose (frequency error). The association between medication knowledge and applied skills with ED visits for pain over the past year was evaluated using Poisson regression adjusting for genotype. RESULTS: One hundred parent/child pairs were included; 50% of parents had low health literacy. Low health literacy was associated with more underdose frequency errors (38% vs. 19%, P = 0.02) on the skills task. On medication knowledge, underdose dosage errors (adjusted incidence rate ratio [aIRR] 2.0, 95% confidence interval [CI] 1.3-3.0) and underdose frequency errors (aIRR, 1.7, 95% CI 1.2-2.6) were associated with a higher rate of ED visits for pain. On the skills task, underdose dosage errors (aIRR 1.6, 95% CI 1.1-2-.4) and underdose frequency errors were associated with more ED visits (aIRR 1.5, 95% CI 1.1-2.1). CONCLUSIONS: For medication knowledge and skills tasks, children of parents who underdosed pain medication had a higher rate of ED visits for pain. Health literate strategies to improve parents' medication skills may improve pain treatment at home and decrease healthcare utilization.

The Benefits and Challenges of Preconsent in a Multisite, Pediatric Sickle Cell Intervention Trial.

Enrollment of patients in sickle cell intervention trials has been challenging due to difficulty in obtaining consent from a legal guardian and lack of collaboration between emergency medicine and hematology. We utilized education and preconsent in a pediatric multisite sickle cell intervention trial to overcome these challenges. Overall, 48 patients were enrolled after being preconsented. Variable Institutional Review Board policies related to preconsent validity and its allowable duration decreased the advantages of preconsent at some sites. The utility of preconsent for future intervention trials largely depends on local Institutional Review Board policies. Preeducation may also benefit the consent process, regardless of site differences.

Targeted Intraoperative Radiotherapy for the Management of Ductal Carcinoma In Situ of the Breast.

Multiple long-term studies have demonstrated a propensity for breast cancer recurrences to develop near the site of the original breast cancer. Recognition of this local recurrence pattern laid the foundation for the development of accelerated partial breast irradiation (APBI) approaches designed to limit the radiation treatment field to the site of the malignancy. However, there is a paucity of data regarding the efficacy of APBI in general, and intraoperative radiotherapy (IORT), in particular, for the management of ductal carcinoma in situ (DCIS). As a result, use of APBI, remains controversial. A prospective nonrandomized trial was designed to determine if patients with pure DCIS considered eligible for concurrent IORT based on preoperative mammography and contrast-enhanced magnetic resonance imaging (CE-MRI) could be successfully treated using IORT with minimal need for additional therapy due to inadequate surgical margins or excessive tumor size. Between November 2007 and June 2014, 35 women underwent bilateral digital mammography and bilateral breast CE-MRI prior to selection for IORT. Patients were deemed eligible for IORT if their lesion was ≤4 cm in maximal diameter on both digital mammography and CE-MRI, pure DCIS on minimally invasive breast biopsy or wide local excision, and considered resectable with clear surgical margins using breast-conserving surgery (BCS). Postoperatively, the DCIS lesion size determined by imaging was compared with lesion size and surgical margin status obtained from the surgical pathology specimen. Thirty-five patients completed IORT. Median patient age was 57 years (range 42-79 years) and median histologic lesion size was 15.6 mm (2-40 mm). No invasive cancer was identified. In more than half of the patients in our study (57.1%), MRI failed to detect a corresponding lesion. Nonetheless, 30 patients met criteria for negative margins (i.e., margins ≥2 mm) whereas five patients had positive margins (<2 mm). Two of the five patients with positive margins underwent mastectomy due to extensive imaging-occult DCIS. Three of the five patients with positive margins underwent successful re-excision at a subsequent operation prior to subsequent whole breast irradiation. A total of 14.3% (5/35) of patients required some form of additional therapy. At 36 months median follow-up (range of 2-83 months, average 42 months), only two patients experienced local recurrences of cancer (DCIS only), yielding a 5.7% local recurrence rate. No deaths or distant recurrences were observed. Imaging-occult DCIS is a challenge for IORT, as it is for all forms of breast-conserving therapy. Nonetheless, 91.4% of patients with DCIS were successfully managed with BCS and IORT alone, with relatively few patients requiring additional therapy.

The proportion of potentially preventable emergency department visits by patients with sickle cell disease.

BACKGROUND: Emergency department (ED) visits by children with sickle cell disease (SCD) are often classified as urgent based on resource utilization. This classification may not accurately reflect the potentially preventable nature of SCD visits. We sought to determine the proportion of SCD crisis-related pediatric ED visits that are possibly preventable. PROCEDURE: We reviewed 2 years of ED visits with a diagnosis of SCD with crisis at a hospital with an established sickle cell program. Criteria for preventable visits were predefined by pediatric hematologists. Non-pain-related chief complaints requiring emergent evaluation or painful episodes preceded by 2 opioid doses were considered not preventable; others were potentially preventable. RESULTS: The study included 603 visits by 187 patients; 33% were potentially preventable. Overall, 29% of visits were emergent based on non-pain-related emergent complaints. Of the remaining pain-related visits, 26% were preceded by 2 or more doses of opioids at home. Visits by children with asthma were 0.58 times as likely to be preventable, due to more non-pain-related emergent chief complaints (32%) and more children (36%) taking 2 or more opioid doses. CONCLUSIONS: Approximately two thirds of SCD crisis-related pediatric ED visits are not immediately preventable; that percentage is higher in children with asthma.

Intravenous magnesium for pediatric sickle cell vaso-occlusive crisis: methodological issues of a randomized controlled trial.

Multiple recent Sickle Cell Disease studies have been terminated due to poor enrollment. We developed methods to overcome past barriers and utilized these to study the efficacy and safety of intravenous magnesium for vaso-occlusive crisis (VOC). We describe the methods of the Intravenous Magnesium in Sickle Vaso-occlusive Crisis (MAGiC) trial and discuss methods used to overcome past barriers. MAGiC was a multi-center randomized double-blind placebo-controlled trial of intravenous magnesium versus normal saline for treatment of VOC. The study was a collaboration between Pediatric Hematologists and Emergency Physicians in the Pediatric Emergency Care Applied Research Network (PECARN). Eligible patients were randomized within 12 hours of receiving intravenous opioids in the Emergency Department (ED) and administered study medication every 8 hours. The primary outcome was hospital length of stay. Associated plasma studies elucidated magnesium's mechanism of action and the pathophysiology of VOC. Health-related quality of life was measured. Site-, protocol-, and patient-related barriers from prior studies were identified and addressed. Limited study staff availability, lack of collaboration with the ED, and difficulty obtaining consent were previously identified barriers. Leveraging PECARN resources, forging close collaborations between Sickle Cell Centers and EDs of participating sites, and approaching eligible patients for prior consent helped overcome these barriers. Participation in the PECARN network and establishment of collaborative arrangements between Sickle Cell Centers and their affiliated EDs are major innovative features of the MAGiC study that allowed improved subject capture. These methods could serve as a model for future studies of VOCs.

Varying patterns of home oxygen use in infants at 23-43 weeks' gestation discharged from United States neonatal intensive care units.

OBJECTIVES: To compare proportions of infants at different gestational ages discharged from the neonatal intensive care unit (NICU) on home oxygen, to determine how many were classified with chronic lung disease based on timing of discharge on home oxygen, and to determine the percentage discharged on home oxygen who received mechanical ventilation. STUDY DESIGN: We evaluated a retrospective cohort of infants of 23-43 weeks' gestational age discharged from 228 NICUs in 2009, using the Pediatrix Clinical Data Warehouse. Multilevel logistic regression analysis identified predictors of home oxygen use among extremely preterm, early-moderate preterm, late preterm, and term infants. Duration of mechanical ventilation and median length of stay were calculated for infants discharged on home oxygen. RESULTS: For the 48877 infants studied, the rate of home oxygen use ranged from 28% (722 of 2621) in extremely preterm infants to 0.7% (246 of 34 934) in late preterm and term infants. Extremely preterm infants composed 56% (722 of 1286) of the infants discharged on home oxygen; late preterm and term infants, 19% (246 of 1286). After gestational age, mechanical ventilation was the main predictor of home oxygen use; however, 61% of the late preterm and term infants discharged on home oxygen did not receive ventilation. The median length of hospital stay was 95 days (IQR, 76-114 days) for extremely preterm infants discharged on home oxygen, but only 15 days (IQR, 10-22 days) for late preterm and term ventilated infants discharged on home oxygen. CONCLUSION: Although home oxygen use is uncommon in later-gestation infants, the greater overall numbers of later-gestation infants contribute significantly to the increased need for home oxygen for infants at NICU discharge. Neither respiratory failure nor lengthy hospitalization is a prerequisite for home oxygen use at later gestational age.
