Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are significant public health concerns around the world. Despite decreasing incidence, there is still a significant disease burden, ...especially in developing nations. This review provides background on the history of ARF, its pathology and treatment, and the current reported worldwide incidence of ARF and prevalence of RHD.
The purpose of this statement is to address the state of evidence on the routine use of pulse oximetry in newborns to detect critical congenital heart disease (CCHD).
A writing group appointed by the ...American Heart Association and the American Academy of Pediatrics reviewed the available literature addressing current detection methods for CCHD, burden of missed and/or delayed diagnosis of CCHD, rationale of oximetry screening, and clinical studies of oximetry in otherwise asymptomatic newborns. MEDLINE database searches from 1966 to 2008 were done for English-language papers using the following search terms: congenital heart disease, pulse oximetry, physical examination, murmur, echocardiography, fetal echocardiography, and newborn screening. The reference lists of identified papers were also searched. Published abstracts from major pediatric scientific meetings in 2006 to 2008 were also reviewed. The American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. In an analysis of pooled studies of oximetry assessment performed after 24 hours of life, the estimated sensitivity for detecting CCHD was 69.6%, and the positive predictive value was 47.0%; however, sensitivity varied dramatically among studies from 0% to 100%. False-positive screens that required further evaluation occurred in only 0.035% of infants screened after 24 hours.
Currently, CCHD is not detected in some newborns until after their hospital discharge, which results in significant morbidity and occasional mortality. Furthermore, routine pulse oximetry performed on asymptomatic newborns after 24 hours of life, but before hospital discharge, may detect CCHD. Routine pulse oximetry performed after 24 hours in hospitals that have on-site pediatric cardiovascular services incurs very low cost and risk of harm. Future studies in larger populations and across a broad range of newborn delivery systems are needed to determine whether this practice should become standard of care in the routine assessment of the neonate.
Options for the circulatory support of pediatric patients under the age of 5 years are currently limited to short-term extracorporeal devices, the use of which is often complicated by infection, ...bleeding, and thromboembolism. Recognizing this void, the National Heart, Lung, and Blood Institute solicited proposals for the development of novel circulatory support systems for infants and children from 2 to 25 kg with congenital or acquired cardiovascular disease. Five contracts were awarded to develop a family of devices that includes (1) an implantable mixed-flow ventricular assist device designed specifically for patients up to 2 years of age, (2) another mixed-flow ventricular assist device that can be implanted intravascularly or extravascularly depending on patient size, (3) compact integrated pediatric cardiopulmonary assist systems, (4) apically implanted axial-flow ventricular assist devices, and (5) pulsatile-flow ventricular assist devices. The common objective for these devices is to reliably provide circulatory support for infants and children while minimizing risks related to infection, bleeding, and thromboembolism. The devices are expected to be ready for clinical studies at the conclusion of the awards in 2009.

The Risk Adjustment for Congenital Heart Surgery (RACHS-1) classification is an established method for predicting mortality for congenital heart disease surgery. It is unknown if this extends to the ...cost of hospitalization or if differences in economic and medical outcomes exist in certain subpopulations. Using data obtained from the University HealthSystem Consortium, we examined inpatient resource use by patients with International Classification of Diseases, Ninth Revision, procedure codes representative of RACHS-1 classifications 1 through 5 and 6 from 2006 to 2012. A total of 15,453 pediatric congenital heart disease surgical admissions were analyzed, with overall mortality of 4.5% (n = 689). As RACHS-1 classification increased, the total cost of hospitalization, hospital charges, total length of stay, length of intensive care unit stay, and mortality increased. Even when controlled for RACHS-1 classification, black patients (n = 2034) had higher total costs ($96,884 ± $3,392, p = 0.003), higher charges ($318,313 ± $12,018, p <0.001), and longer length of stay (20.4 ± 0.7 days, p <0.001) compared with white patients ($85,396 ± $1,382, $285,622 ± $5,090, and 18.0 ± 0.3 days, respectively). Hispanic patients had similarly disparate outcomes ($104,292 ± $2,759, $351,371 ± $10,627, and 23.0 ± 0.6 days, respectively) and also spent longer in the intensive care unit (14.9 ± 0.5 days, p <0.001). In conclusion, medical and economic measures increased predictably with increased procedure risk, and admissions for black and Hispanic patients were longer and more expensive than those of their white counterparts but without increased mortality.

Objective To decrease interruptions around a centrally-located, centralised, open paediatric medication station. Methods Several established human factors methodologies were used to study paediatric ...medication administration, including cases with ‘walk through’ and verbal protocols; semi-structured interviews, including critical incident analysis; hierarchical task analysis; and observation. Results Inexpensive barriers were constructed that protected the tasks likely to lead to errors if interrupted. Meanwhile, sight lines were maintained preserving a family-friendly sense of accessibility of nurses, staff situation awareness and collegiality. Interruptions were significantly reduced and staff attitudes towards the station were significantly improved. Discussion Targeted barriers may prove useful in other interruptive and chaotic hospital workspaces. They do not require costly training, can be achieved inexpensively and may reduce distractions and interruptions during tasks vulnerable to error. Additionally, the human factors methodologies employed can be applied to other safety improvement projects.
Hospitals are increasingly compared based on clinical outcomes adjusted for severity of illness. Multiple methods exist to adjust for differences between patients. The challenge for consumers of this ...information, both the public and healthcare providers, is interpreting differences in risk adjustment models particularly when models differ in their use of administrative and physiologic data. We set to examine how administrative and physiologic models compare to each when applied to critically ill patients.
We prospectively abstracted variables for a physiologic and administrative model of mortality from two intensive care units in the United States. Predicted mortality was compared through the Pearsons Product coefficient and Bland-Altman analysis. A subgroup of patients admitted directly from the emergency department was analyzed to remove potential confounding changes in condition prior to ICU admission.
We included 556 patients from two academic medical centers in this analysis. The administrative model and physiologic models predicted mortalities for the combined cohort were 15.3% (95% CI 13.7%, 16.8%) and 24.6% (95% CI 22.7%, 26.5%) (t-test p-value<0.001). The r(2) for these models was 0.297. The Bland-Atlman plot suggests that at low predicted mortality there was good agreement; however, as mortality increased the models diverged. Similar results were found when analyzing a subgroup of patients admitted directly from the emergency department. When comparing the two hospitals, there was a statistical difference when using the administrative model but not the physiologic model. Unexplained mortality, defined as those patients who died who had a predicted mortality less than 10%, was a rare event by either model.
In conclusion, while it has been shown that administrative models provide estimates of mortality that are similar to physiologic models in non-critically ill patients with pneumonia, our results suggest this finding can not be applied globally to patients admitted to intensive care units. As patients and providers increasingly use publicly reported information in making health care decisions and referrals, it is critical that the provided information be understood. Our results suggest that severity of illness may influence the mortality index in administrative models. We suggest that when interpreting "report cards" or metrics, health care providers determine how the risk adjustment was made and compares to other risk adjustment models.

BACKGROUND Meaningful education of residents in systems-based practice is notoriously challenging, despite its recognition as 1 of the 6 Accreditation Council for Graduate Medical Education core ...competencies. To address this challenge, surgery residents and other members of the health care team were organized into interdisciplinary workgroups that were tasked with developing solutions to “systems issues” confronted on a daily basis. The project’s goals included providing more meaningful, hands-on educational experience for residents in system-based practice, while also generating practical solutions to workflow issues through interprofessional collaboration. PROJECT DESIGN Project participants included all surgery residents at the University of Virginia in Charlottesville, VA, as well as surgical health care professionals across all disciplines. Participants were organized into workgroups. Over the course of 3 sessions, each of 1-hour, each workgroup identified commonly encountered systems issues, chose 1 issue to address, and determined an implementable solution for this issue. In total, 140 participants were divided among 13 workgroups. PROJECT EXECUTION Workgroup topics ranged from improving paging etiquette to standardizing interdisciplinary communication. In total, 9 of the 13 proposals have been piloted or fully implemented as standard practice at our institution, either within a single unit or over the entire health system. DISCUSSION This project demonstrates an innovative approach toward resident education in system-based practice, providing residents with a hands-on experience in problem solving from a systems perspective. These interdisciplinary workgroups generated effective solutions to issues that were meaningful to frontline health care providers. Interdisciplinary collaboration within the workgroups served as a valuable team-building exercise to improve relations between the disciplines. This project can serve as a model for other institutions desiring meaningful education in the Accreditation Council for Graduate Medical Education competency of systems-based practice.

Background and Aims
Chylothorax (CTX) occurs in 3% to 6% of children after surgery for congenital heart disease with significant morbidity and mortality. Octreotide has been proposed as therapy, but ...there are no predictors of response. The objective of this study was to identify possible predictors of response to octreotide.
Methods
Single‐center retrospective review of patients who developed CTX after cardiac surgery. Data collected included demographics, cardiac lesion, surgical data, hospital course, CTX volume and duration, and interventions for CTX. Patients who received octreotide as part of their therapy were compared to those who did not.
Results
A total of 1150 patients underwent 1455 cardiac surgeries with 67 (4.6%) episodes of CTX. Patients with CTX were younger, lower weight, more likely to undergo cardiopulmonary bypass, and had higher RACHS‐1 scores and mortality. Nineteen patients with CTX received octreotide as part of their treatment and six (32%) had at least 50% reduction in CTX volume. Patients who responded to octreotide had lower CTX volume (18 mL/kg/day vs. 55 mL/kg/day, p = 0.023) and a higher proportion of patients with single ventricle anatomy (67% vs. 18%, p = 0.046).
Conclusions
There is a subset of patients who seem to respond to octreotide, but they have lower CTX volume and may have already been improving before octreotide therapy. Patients with single ventricle anatomy seemed to respond to octreotide and may benefit from its use. doi: 10.1111/jocs.12263 (J Card Surg 2014;29:259–264)

Compliance with secondary antibiotic prophylaxis for acute rheumatic fever (ARF) should decrease the rate of recurrence; however, efficacy in a highly endemic area has not been studied. A ...retrospective chart review of patients <21 years old with a diagnosis of ARF in the Northern Mariana Islands was performed. Patient compliance with benzathine penicillin G (BPG) prophylaxis was assessed. One hundred forty-four patients with ARF were identified and considered eligible, and the recurrence rate was 38%. Mean level of compliance with BPG was 59% in patients with no recurrence of ARF and 57% in patients with recurrence of ARF. Level of compliance was not shown to be associated with odds of recurrence. There was a trend toward significance (
p
= 0.06), with those patients who had carditis at the time of diagnosis of ARF having higher odds of recurrence. A remarkably high recurrence rate of ARF was found in this population, but there was no difference in compliance with secondary antibiotic prophylaxis between those with and without recurrence of ARF. These findings stress the need to improve methods of primary prevention and secondary antibiotic prophylaxis for ARF.
