Diagnostic accuracy of uriSed automated urine microscopic sediment analyzer and dipstick parameters in predicting urine culture test results.
Urinary tract infection (UTI) is one of the most common types of infection. Currently, diagnosis is primarily based on microbiologic culture, which is time- and labor-consuming. The aim of this study was to assess the diagnostic accuracy of urinalysis results from UriSed (77 Electronica, Budapest, Hungary), an automated microscopic image-based sediment analyzer, in predicting positive urine cultures. ⋯ Although the specificity of the UriSed analyzer was within acceptable limits, the sensitivity value was low. Thus, UriSed urinalysis resuIts do not accurately predict the outcome of culture.

Comparative Study
Analytic performance of bacteriuria and leukocyturia obtained by UriSed in culture positive urinary tract infections.
Urine analysis is one of the most common tests for assessing urinary-tract infections, which are the most frequently occurring infectious diseases in community populations. Urine culture is still the 'gold standard' for the detection of urinary tract infection, however, it is time- and labor-intensive and and has a high number of unnecessary cultures. The aim of this study was to evaluate the analytical and diagnostic performance of a new urinalysis system LabUMat with UriSed (77 Elektronika, Budapest, Hungary) in comparison to urine culture as the reference method. ⋯ When screening with the UriSed for community-acquired urinary tract infection, a cut-off value of 85 bacteria/microL and 13 WBCs/microL should be adopted. Diagnostic performance of UriSed is satisfactory and use of this instrument is a reliable method for screening out a major part of the culture negative samples. It would improve the efficiency of microbiology laboratory, and unnecessary antibiotic prescriptions could be reduced.

Inappropriate treatment of catheter-associated asymptomatic bacteriuria in a tertiary care hospital.
Evidence-based guidelines state that asymptomatic bacteriuria is not a clinically significant condition in men and nonpregnant women and that treatment is unlikely to confer clinical benefit. We hypothesized that, among patients with indwelling catheters or condom collection systems, many who receive a diagnosis of and are treated for catheter-associated urinary tract infection (CAUTI) actually have asymptomatic bacteriuria and, therefore, that antibiotic therapy is inappropriate. ⋯ Better recognition of CAABU and the distinction between this condition and CAUTI, consistent with evidence-based guidelines, may play a key role in reducing unneeded antibiotic usage in hospitalized patients.
