Restricted Reporting for Positive Urine Cultures

February 26, 2020 updated by: Peter Daley, Memorial University of Newfoundland

Restricted Reporting for Positive Urine Cultures Randomized Controlled Trial

Asymptomatic bacteriuria (AB) is a condition in which bacteria are detected in urine culture without urinary symptoms. The inappropriate use of antibiotic treatment for AB selects bacterial flora to express resistance mutations. Reducing inappropriate antibiotic use for AB is difficult, since the microbiology laboratory cannot distinguish patients with AB. The investigators study will use a restricted laboratory report requesting the physician to call the laboratory for culture results. The restricted report may reduce the rate of inappropriate treatment of AB.

Detailed Description

Positive urine cultures during the study period will be randomized to restricted microbiology laboratory reporting or standard microbiology laboratory reporting. Physician or patient consent will not be collected. Patient records will be assessed by the investigator to determine if patients have AB or urinary tract infection. Physician antibiotic treatment decision in both groups will be collected.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Standard Reporting
Microbiology laboratory will report identification and susceptibility results
Experimental: Restricted Reporting
Microbiology laboratory will report "Positive urine cultures may represent asymptomatic bacteriuria or urinary tract infection. If urinary tract infection is suspected clinically, please call 777-xxxx (researcher mobile phone) for identification and susceptibility results"
Behavioral: Restricted Reporting
An abbreviated version of the microbiology report indicating that growth is present and the physician should call the lab for further details if clinically important
