OBJECTIVES To compare the patient characteristics, clinical conditions, and short-term recidivism rates of emergency department (ED) patients who leave against medical advice (AMA) with those who leave without being seen (LWBS) or complete their ED care. METHODS All eligible patients who visited the ED between July 1, 2004, and June 30, 2005 (N = 31,252)(More)
STUDY OBJECTIVE We identify patient characteristics associated with uncompleted visits to the emergency department (ED). METHODS We used registration and billing data to conduct a pair-matched case-control study. ED patients who left without being seen (cases) between July 1 and December 31, 2004, were matched to patients who stayed and were treated(More)
BACKGROUND The repulsive guidance molecule (RGM) proteins, originally discovered for their roles in neuronal development, have been recently identified as co-receptors in the bone morphogenetic protein (BMP) signaling pathway. BMPs are members of the TGFbeta superfamily of signaling cytokines, and serve to regulate many aspects of cellular growth and(More)
OBJECTIVE Children with moderate to severe traumatic brain injury (TBI) show early neurobehavioral deficits that can persist several years after injury. Despite the negative impact that TBI can have on a child's physical, cognitive, and psychosocial well-being, only 1 study to date has documented the receipt of health care services after acute care and the(More)
BACKGROUND AND OBJECTIVE Children with traumatic brain injuries often show impaired executive function (the ability to carry out goal-directed behavior). The Behavior Rating Inventory of Executive Function, a caregiver-report questionnaire, measures executive function in everyday activities. In this study, our goal was to use the Behavior Rating Inventory(More)
OBJECTIVES This consensus conference presentation article focuses on methods of measuring crowding. The authors compare daily versus hourly measures, static versus dynamic measures, and the use of linear or logistic regression models versus survival analysis models to estimate the effect of crowding on an outcome. METHODS Emergency department (ED) visit(More)
STUDY OBJECTIVE We determine the effect of crowding on emergency department (ED) waiting room, treatment, and boarding times across multiple sites and acuity groups. METHODS This was a retrospective cohort study that included ED visit and inpatient medicine occupancy data for a 1-year period at 4 EDs. We measured crowding at 30-minute intervals throughout(More)
OBJECTIVES To document health-related quality of life (HRQOL) of children with traumatic brain injury (TBI) and to examine the relationship between TBI severity and HRQOL during the first year after injury. DESIGN Prospective cohort study. SETTING Four pediatric level I trauma centers. PATIENTS Children with TBI (n = 330). MAIN EXPOSURE Traumatic(More)
STUDY OBJECTIVE We examine the validity of the emergency department (ED) occupancy rate as a measure of crowding by comparing it to the Emergency Department Work Index Score (EDWIN), a previously validated scale. METHODS A multicenter validation study was conducted according to ED visit data from 6 academic EDs for a 3-month period in 2005. Hourly ED(More)
OBJECTIVES To assess the reliability and validity of the Pediatric Quality of Life Inventory, version 4.0 (PedsQL), and to compare it with that of the Behavior Rating Inventory of Executive Function (BRIEF) among children with traumatic brain injury (TBI). DESIGN Prospective cohort study that documented the health-related quality of life of 391 children(More)
