We evaluated the relationship between apical surface fluid (ASF) and protein secretion in Calu-3 cells grown at an air-liquid interface. Calu-3 monolayers responded to forskolin, a cystic fibrosis transmembrane regulator (CFTR) channel agonist, by secreting a significant amount of ASF. Such a response from Calu-3 monolayers was not observed with CFTR(More)
INTRODUCTION Data quality and fitness for analysis are crucial if outputs of analyses of electronic health record data or administrative claims data should be trusted by the public and the research community. METHODS We describe a data quality analysis tool (called Achilles Heel) developed by the Observational Health Data Sciences and Informatics(More)
BACKGROUND AND OBJECTIVES Palivizumab can reduce hospitalizations due to respiratory syncytial virus (RSV), but many eligible infants fail to receive the full 5-dose series. The efficacy of clinical decision support (CDS) in fostering palivizumab receipt has not been studied. We sought a comprehensive solution for identifying eligible patients and(More)
This article examines the current role of telehealth as a tool in the delivery of pediatric health care. It defines telemedicine and telehealth and provides an overview of different types of telehealth services. The article then explores the potential of telehealth to improve pediatric health care quality and safety through increased access to care,(More)
Objective PEDSnet is a clinical data research network (CDRN) that aggregates electronic health record data from multiple children's hospitals to enable large-scale research. Assessing data quality to ensure suitability for conducting research is a key requirement in PEDSnet. This study presents a range of data quality issues identified over a period of 18(More)
OBJECTIVE To examine the effect of ambulatory health care processes on asthma hospitalizations. METHODS A retrospective cohort study using electronic health records was completed. Patients aged 2-18 years receiving health care from 1 of 5 urban practices between Jan 1, 2004 and Dec 31, 2008 with asthma documented on their problem list were included.(More)
BACKGROUND Neonates exposed to mechanical ventilation may develop bronchopulmonary dysplasia (BPD). BPD neonates exhibit a 25-30% increase in energy expenditure which may decrease the rate of growth and development. Heliox has been shown to improve pulmonary function and may decrease energy expenditure. We hypothesized that heliox would provide a safe(More)
