Comparison microbiological indices in spontaneous voided urine or urine obtained from incontinence material

This dataset belongs to the PROGRESS study (diagnosing urine tract infections in elderly nursing home residents)The data are for a comparison of urine culture and urine dipstick results in urine that is spontaneously voided or obtained from incontinence material. Obtaining a urine specimen for diagnosis is often a challenge in this population. If urine obtained from incontinence material could be used instead, this would make it possible that UTI treatment is started more frequently based on a proper microbiological evidence, rather than empirically. We performed a laboratory-based non-inferiority study comparing these two sources of urine with regards to the presence of uropathogens in the culture, the number of colony counts in the culture, and the semi-quantitive results of the dipstick test (leucocytes and nitrite).Urine specimens were randomly sampled from routine specimens present in a single bacteriology laboratory in a tertiary hospital. Specimens were used within 24 hours of voiding. Remnants of the urine (10 ml) were poured on incontinence material, incubated for 3 hours, after which dissected material was added to 9 ml of sterile water, and vortexed for 10 seconds. Bacterial cultures were conducted using routine procedures in which bacterial growth was assessed after overnight incubation, and species were identified though Maldi-tof mass spectrometry. Dipstick analysis used Combur2 from Roche.Data structureThe file is in a .cvs format outputted through STATA version 16.0. The dataset is organised in the long format. The variable “pair” links the two urine sources. CodebookThe file is in a .xlsx format. It lists the variables present in the database with their type, description, categorisation, and additional comments where applicable.
