Although the risk factors for acquiring infection by extended-spectrum beta-lactamase (ESBL)-producing bacteria have been investigated in hospitalized patients, such risk factors have not been defined in the community setting. In this study, clinical data from a total of 311 nonhospitalized patients with community-acquired urinary tract infection (128 with(More)
The effect of oral cimetidine or ranitidine on the pharmacokinetics of the nonsteroidal anti-inflammatory agent flurbiprofen was studied. Nine healthy volunteers participated in the study. The subjects were divided into three groups, and each group alternated therapy with each of the following treatments: flurbiprofen 200 mg (two 100-mg tablets),(More)
False physiologic monitor alarms are extremely common in the hospital environment. High false alarm rates have the potential to lead to alarm fatigue, leading nurses to delay their responses to alarms, ignore alarms, or disable them entirely. Recent evidence from the U.S. Food and Drug Administration (FDA) and The Joint Commission has demonstrated a link(More)
BACKGROUND Alarm fatigue is reported to be a major threat to patient safety, yet little empirical data support its existence in the hospital. OBJECTIVE To determine if nurses exposed to high rates of nonactionable physiologic monitor alarms respond more slowly to subsequent alarms that could represent life-threatening conditions. DESIGN Observational(More)
Learning to use a new electronic anesthesia information management system can be challenging. Documenting anesthetic events, medication administration, and airway management in an unfamiliar system while simultaneously caring for a patient with the vigilance required for safe anesthesia can be distracting and risky. This technical report describes a(More)
This paper describes an analog computer program used to predict warfarin dosages following an initial three daily doses of 10 mg. The program simulates the patient's response to warfarin and suggested dosages can be entered into the program daily to predict the dose necessary for the patient. Warfarin dosage predictions were made for 29 patients. There was(More)
Aparent partition coefficients and inhibitory activities against sensitive and resistant Escherichia coli were determined for 14 tetracyclines. The difference in the kinetics of inhibition of the two organisms is discussed in terms of their permeabilities. The partition coefficients were determined in an octanol-buffer system. Values for eight compounds(More)
