BACKGROUND Nursing workload is increasingly thought to contribute to both nurses' quality of working life and quality/safety of care. Prior studies lack a coherent model for conceptualising and measuring the effects of workload in healthcare. In contrast, we conceptualised a human factors model for workload specifying workload at three distinct levels of(More)
OBJECTIVES To evaluate the efficacy of a specific protocol of conservative therapy for infant gastroesophageal reflux. STUDY DESIGN Retrospective evaluation of the response to telephone teaching of conservative therapy by a single instructor as part of the screening process for a pharmacotherapy study of infantile reflux. Feeding modifications included(More)
Eosinophilic esophagitis, long known to be a feature of acid reflux, has recently been described in patients with food allergies and macroscopically furrowed esophagus. The pathophysiology and optimal management of patients with eosinophilic esophagitis is unclear. We describe our clinical experience related to eosinophilic esophagitis and obstructive(More)
To determine whether thickening of infant formula feedings with rice cereal increases coughing, we studied 25 infants from birth to 6 months of age, referred for evaluation of gastroesophageal reflux. Coughing was blindly quantified after each of a pair of isocaloric meals (one thickened and one unthickened). Coughing was more frequent after thickened(More)
To improve history-taking of infants with suspected gastroesophageal reflux, we developed an Infant Gastroesophageal Reflux Questionnaire consisting of 161 items covering demographics, symptoms (regurgitation, weight deficit, respiratory difficulties, fussiness, apnea, and pain or bleeding of esophagitis), and possible causes (feeding volume and frequency,(More)
To identify the prevalence of reflux symptoms in normal infants, to characterize the diagnostic validity of a previously described 138-item Infant Gastroesophageal Reflux Questionnaire (I-GERQ) for separating normal infants from those with gastroesophageal reflux disease (GERD), and to identify potentially provocative caretaking practices, we administered(More)
OBJECTIVES A genetic locus for pediatric reflux was proposed on chromosome 13q14, but is unconfirmed in independent kindreds. We sought to test this locus in families with multiple affected infants from our database of well characterized infants with reflux. METHODS We screened the database for families with multiple affected infants. Affected proband(More)
BACKGROUND Gastro-oesophageal reflux afflicts up to 7% of all infants. Histamine-2 receptor antagonists are the most commonly prescribed medications for this disorder, but few controlled studies support this practice. AIM To evaluate the safety and efficacy of famotidine for infant gastro-oesophageal reflux disease. METHODS Thirty-five infants, 1.3-10.5(More)
Gastroesophageal reflux is a disorder with well-characterized histopathological features in the adult, but the incidence and pathogenesis of epithelial injury in children are poorly understood. Esophageal suction biopsies from 80 infants exhibiting symptoms of reflux were studied by computer-assisted image analysis and the results compared to routine(More)
OBJECTIVES To determine the natural history of infant gastroesophageal reflux disease (GERD) with esophagitis, we periodically analyzed symptoms and biopsies during 1 yr in 19 infants randomly assigned to placebo in a pharmacotherapy study. METHODS One hundred infants who were referred during 1994-1999 for GERD, were unresponsive to 2-wk life-style(More)
