DescriptionPurpose of Project
Urine cultures are one of the most important lab tests utilized, in the work up of a urinary tract infection (UTI) amongst patients with neurological diseases. The purpose of this project was to assess the current practice of the use of urine cultures in this patient population to improve practice.
Methodology
A retrospective chart review was conducted for patients in a Neuro-Oncology acute care unit. Participants included 53 patients over 60 days. Data was retrieved from the quality improvement (QI) department. Descriptive statistics were used to analyze the results of urine culture utilization.
Results
A total of 64 urine cultures were ordered from the 53-patient convenience sample over 60 days. Out of 64 urine cultures ordered, 70.3% (45) were negative, 18.8% (12) were positive and 10.9 % (7) were contaminated samples. There were 22.64% (12) of patients who had >1 urine culture ordered in one hospital stay. Of the 22.64%, there were 23 orders placed, which represents 35.94% of the total amount of urine cultures ordered. Patients w/ > or = 2 orders within 3 days or less represented 50% (6) of increased usage of urine cultures.
Implications
Most Neuro-Oncology patients received a urine culture order, many times without checking for previous orders, as there were many repeated orders sent to the lab. The amount of negative urine culture orders compared to the amount positive indicates, that many patients might not need a urine culture during their hospital stay.
