  • Background: The diagnosis and management of catheter associated urinary tract infections (CAUTIs) starts by obtaining a urine culture, often triggered by subjective observations that may not relate to infection.

    Methods: We surveyed medicine and surgery resident physicians (RPs) in 2 large teaching hospitals on what triggers a urine culture in a catheterized patient and when to administer antimicrobials for a positive urine culture result.

    Results: 124 RPs participated in the survey. About half of the RPs (58/124; 46.8%) felt their knowledge about the diagnosis of CAUTI is above average or excellent, and 68.5% received lectures addressing appropriate indications for urine cultures within the last year. RPs showed less than optimal knowledge on what triggers ordering a urine culture in patients with an indwelling catheter with RPs obtaining urine cultures for foul smelling urine (45%), cloudy urine (42%), sediments in urine (26.5%), hematuria (16.6%), chronic urinary catheter on admission (16.1%), and darker looking urine (15%). Residents tended to order more urine cultures the higher the urine analysis white cell counts: for 25 cells (33.3%), for 100 cells (67.5%), and for 500 cells (82.5%). For asymptomatic bacteriuria, 58.3% would change the catheter, 24.2% would treat bacteriuria for a patient going for a non-urologic surgery, and 17.5% will administer antibiotics.

    Conclusion: There are significant opportunities for improvement in training the resident physicians regarding the appropriate reasons for collecting urine cultures, the clinical diagnosis of CAUTI, and management. We suggest programs to evaluate their residents’ knowledge and practice, and implement educational interventions if needed.
