PURPOSE To present a normative volumetric database, spanning 5 decades of life, of cerebrospinal fluid, subarachnoid cerebrospinal fluid, total brain volume, total ventricular volume (component ventricular volumes of lateral, temporal horn, and third and fourth ventricles) and estimates of white and gray matter, based on a multispectral segmentation of(More)
BACKGROUND Randomized, controlled trials have shown that prophylactic antibiotics are effective in preventing surgical-wound infections. However, it is uncertain how the timing of antibiotic administration affects the risk of surgical-wound infection in actual clinical practice. METHODS We prospectively monitored the timing of antibiotic prophylaxis and(More)
OBJECTIVE The aim of the study was to investigate the relationship between blood glucose level, measured as HbA(1c), and frequency of self-monitoring in patients with type 2 diabetes. Daily self-monitoring is believed to be important for patients treated with insulin or oral agents to detect asymptomatic hypoglycemia and to guide patient and provider(More)
OBJECTIVE To characterize complications among infants hospitalized for bronchiolitis or respiratory syncytial virus (RSV). STUDY DESIGN Retrospective data from 684 infants with bronchiolitis or RSV pneumonia, < or =1 year old, admitted to 10 children's hospitals from April 1995 to September 1996. Outcomes included complication rates and effects on(More)
OBJECTIVES To determine if gestational age (GA) is independently associated with hospital resource use and outcomes among infants hospitalized for respiratory syncytial virus (RSV). STUDY DESIGN Analysis of retrospective data from 304 infants (</=1 year) with bronchiolitis or RSV pneumonia admitted to nine children's hospitals from April 1995 to September(More)
UNLABELLED Horn SD, DeJong G, Smout RJ, Gassaway J, James R, Conroy B. Stroke rehabilitation patients, practice, and outcomes: is earlier and more aggressive therapy better? OBJECTIVE To examine associations of patient characteristics, rehabilitation therapies, neurotropic medications, nutritional support, and timing of initiation of rehabilitation with(More)
We review the advantages and disadvantages of several goodness-of-fit tests which may be used with discrete data: the multinomial test, the likelihood ratio test, the X2 test, the two-stage X2 test and the discrete Kolmogorov-Smirnov test. Although the X2 test is the best known and most widely used of these tests, its use with small sample sizes is(More)
OBJECTIVE To prospectively monitor occupational therapy activities and intervention techniques used during inpatient stroke rehabilitation in order to provide a description of current clinical practice. METHODS Data were collected prospectively from 954 clients with stroke receiving occupational therapy from six U.S. rehabilitation hospitals. Descriptive(More)
BACKGROUND AND PURPOSE Improving clinical outcomes requires continuous measurement and interpretation in conjunction with treatment process and patient characteristics. The purposes of this study were: (1) to describe implementation and integration of electronic functional status outcomes into an electronic health record (EHR) for the promotion of clinical(More)
OBJECTIVE Hospital care for children with viral lower respiratory illness (VLRI) is highly variable, and its relationship to severity and impact on outcome is unclear. Using the Pediatric Comprehensive Severity Index, we analyzed the correlation of institutional practice variation with severity and resource utilization in 10 children's medical centers. (More)
