Abstract Background A urinary tract infection (UTI) is very common and patients frequently present to their General Practitioner and emergency department with symptoms. Diagnosis of the infection is made by examining fresh urine with microscopy, to detect white cells and epithelial cells shed from the bladder or by submitting the urine for microbial culture. Patients are often requested to provide a urine specimen, but very little is known about the patient experiences of carrying out the task or their preference of specimen collection method. The aim of this study was to explore patient experiences and preferences between four different urine specimen collection methods for diagnosing the presence of a UTI.Materials Semi-structured interviews were conducted and explored patient experiences of four different urine specimen collection methods (midstream urine specimen (MSU), catheter specimen (CSU), Peezy MSU™ and Natural void). The interviews consisted of four open-ended questions and all data were collated and organised using NVivo to establish themes that emerged from the data.Results The natural void without technique was repeatedly referred to and was regarded as being the most straightforward of all of the sampling methods. Pain symptoms were described only in the catheter method and not in the MSU, Peezy MSU™ or natural void method. The catheter was regarded as the urine collection method that produced the best specimen for diagnostic testing by the patients’. Conclusion A majority of the participants expressed the desire for straightforward urine sampling methods and preferred the natural void as a standard method in clinical practice.

Abstract:The problem of deciding the optimal sequence of diagnostic tests can be structured in decision trees, but unmanageable bushy decision trees result when the sequence of two or more tests is investigated. Most modelling techniques include tests on the basis of gain in certainty. The aim of this study was to explore a model for optimizing the sequence of diagnostic tests based on efficiency criteria. The probability modifying plot shows, when in a specific test sequence further testing is redundant and which costs are involved. In this way different sequences can be compared. The model is illustrated with data on urinary tract infection. The sequence of diagnostic tests was optimized on the basis of efficiency, which was either defined as the test sequence with the least number of tests or the least total cost for testing. Further research on the model is needed to handle current limitations.

Background: Antibiotic resistance emerged as clinical problem challenge the effective treatment of infections. Virulence factor may play an important role in the influence of antimicrobial resistance. Objective: To determine the frequency of resistance gene in E. coli clinical isolates from women with urinary tract infection. Materials and Methods: Fifteen E.coli clinical isolates were tested by PCR to determine their molecular characterization. Results: The bla CTX –M gene was not detected in 6.7% out of the tested 15 E. coli clinical isolates from women with urinary tract infection. However, bla OXA gene was detected in all E. coli tested clinical isolates from pregnant women, female student and diabetic women with urinary tract infection. While bla TEM gene and bla SHV gene were not detected in 33.3% and 40% out of the tested E. coli clinical isolates respectively. Conclusions: Four types of ESBL genes were detected, and shows new trend of distribution, which indicated the predominance of OXA and CTX-M genes.
