Objective. To determine whether a computerized decision support system could increase the proportion of oral quinolone antibiotic orders placed for hospitalized patients.
Design. Prospective, interrupted time‐series analysis.
Setting. University hospital in the south‐eastern United States.
Subjects. Inpatient quinolone orders placed from 1 February 2001 to 31 January 2003.
Intervention. A web‐based intervention was deployed as part of an existing order entry system at a university hospital on 5 February 2002. Based on an automated query of active medication and diet orders, some users ordering intravenous quinolones were presented with a suggestion to consider choosing an oral formulation.
Main outcome measure. The proportion of inpatient quinolone orders placed for oral formulations before and after deployment of the intervention.
Results. There were a total of 15 194 quinolone orders during the study period, of which 8962 (59%) were for oral forms. Orders for oral quinolones increased from 4202 (56%) before the intervention to 4760 (62%) after, without a change in total orders. In the time‐series analysis, there was an overall 5.6% increase (95% CI 2.8–8.4%; P < 0.001) in weekly oral quinolone orders due to the intervention, with the greatest effect on nonintensive care medical units.
Conclusions. A web‐based intervention was able to increase oral quinolone orders in hospitalized patients. This is one of the first studies to demonstrate a significant effect of a computerized intervention on dosing route within an antibiotic class. This model could be applied to other antibiotics or other drug classes with good oral bioavailability.
Herpes simplex virus (HSV) pseudotumor is a rare presentation of HSV and has not been previously reported in the stomach. A 51-year-old man with a medical history of HIV presented with new-onset dysphagia. Endoscopy revealed an HSV-positive mass at the gastroesophageal junction. After antiviral treatment, the patient returned with a 100-pound unintentional weight loss. Computed tomography showed an infiltrative mass with enlarged lymph nodes. The mass had progressed despite HSV treatment, and a repeat set of biopsies were negative for HSV with cells concerning for B-cell lymphoma. The patient was taken to the operating room for a full-thickness biopsy because of increasing concern for malignancy. The procedure was complicated by gastric perforation, leading to a total gastrectomy. Final pathology demonstrated an HSV-positive pseudotumor, negative for malignancy. It is important to diagnose gastric masses, especially in HIV-positive patients at high risk of infection and malignancy. However, immunocompromised patients with an HSV-positive mass should be treated for HSV pseudotumor with a longer than standard duration of antiviral therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
