Leis, MD MSc FRCPC Division of Infectious Diseases Sunnybrook Health Sciences Centre Physician Lead, Antimicrobial Stewardship Team Faculty Quality Improvement Advisor, Centre for QuIPS Assistant Professor, Department of Medicine University of Toronto Sunnybrook Health Sciences Centre Toronto, Ontario Medical Research: What is the background for this study? What are the main findings? Dr. Leis: We know that urinary tract infections are frequently diagnosed among general medicine patients who lack symptoms of this infection.  We wondered whether urinalysis ordering practices in the Emergency Department influence diagnosis and treatment for urinary tract infection among these asymptomatic patients.  We found that over half of patients admitted to the general medicine service underwent a urinalysis in the Emergency Department of which over 80% lacked a clinical indication for this test.  Urinalysis results among these asymptomatic patients did influence diagnosis as patients with incidental positive results were more likely to undergo urine cultures and treatment with antibiotics for urinary tract infection.  The study suggests that unnecessary urinalysis ordering contributes to over-diagnosis and treatment of urinary tract infection among patients admitted to general medicine service.
