A multidisciplinary approach is needed to use this quality indicator. Evaluation of urine strip and sediment according to the presence of contamination effect the rates of accurate test result, guidance of the clinician correctly, patient follow-up and requesting new sample. This feature also fulfils the rule of objectivity in quality indicators. It also plays an important role in the monitoring and effectiveness of regulatory and preventive activities. Material and Methods: Urine culture samples which were resulted as contaminated and synchronous full urinalysis test results were scanned retrospectively between July 2017 and December 2017. The patients were evaluated according to their age, sex, and being inpatient or outpatient. Strip and microscopy findings were evaluated from the results of full urine analysis. Results: 1537 urine culture test results were analyzed in 6 months for the study. Those which were considered as contamination were evaluated together with their total urine analysis at the same time. It was found that 82% were female, 18% were male, 58% were older than 65 years, 24% were between 18-65 years, 11% were <1-year-old of these patients. The test was requested 67% and 33% respectively from outpatient and inpatient. Leukocyte esterase and nitrite were found positive %33 and %16 respectively in urine strips. When urine microscopy was evaluated, 52% had abundant bacteria and 56% had more than 5 leukocytes in each area. It was found that 63.3% of the patient have no signs in microscopy or strip in <1-year-old group. Conclusions: In our study, it was found that contamination rates were higher especially over 65 years and female sex. It is important to explain the method of sampling and to be more careful when approving the test results of full urine analysis in this population. Considerations during sample collection and the selection of materials are of great importance for clinical follow-up in younger than 1-year-old population.eninfo:eu-repo/semantics/openAccessConference Object1131
