African American female with renal failure presenting with skin lesions: a case report.

Use of on-line evidence-based resources at the point of care.

Background And Objectives: The utility of on-line evidence-based summary databases for answering clinical questions at the point of care is not well understood. Our objectives were to determine if family physician faculty could answer their questions using on-line resources and the proportion of answers that influenced patient care.

Methods: This was a prospective study in which clinical faculty in an urban residency training office recorded their clinical questions and their search results.
