The Effect of Collection Method On Urinalysis Results in Women With Pelvic Organ Prolapse

Translating Evidence into Clinical Practice: Adding to the Evidence Base: The Effect of Collection Method On Urinalysis in Women with Pelvic Organ Prolapse

“…Examining the study under review (Shalom et al, 2014) for internal validity or whether it answers the intended questions or hypotheses revealed that the researchers stated a hypothesis that indicated the midstream clean catch urine would not be as effective for women with pelvic organ prolapse as the sterile catheterized urine based on specific parameters of the urinalysis. To that end, they set about seeking agreement between the two methods of urinalysis as well as seeking differences.…”

“…Having stated the study (Shalom et al, 2014) is internally valid, it offers opportunity to discuss the sampling, design, and statistics employed. The researchers stated how the sample size was determined but not whether there was any randomization involved.…”

“…The researchers (Shalom et al, 2014) have indicated that the lack of agreement between the methods has to do with the advanced prolapse present in the women of the sample population. T'his argument seems possible and even likely.…”

“…The method of urine collection is the focus of the study by Shalom, Liao, O'Shaughnessy, and Winkler (2014), and the researchers have chosen to measure agreement between the two methods based on six outcomes of the urinalysis. Urinalysis is needed to determine the presence of any infection.…”

“…Of interest in the current study under review (Shalom et al, 2014) is the use of fhe kappa statistic for measuring agreement between raters on a urinalysis method. Aspects of the study itself as well as the use of the kappa statistic will be explored in this review.…”
