Randomized Controlled Trial Comparative Study Clinical TrialIncidence of urinary tract infections in patients with short-term indwelling urethral catheters: a comparison between a 3-day urinary drainage bag change and no change regimens.
The current practice of caring for hospitalized patients with indwelling urethral catheters in Siriraj Hospital is to change the drainage bag every 3 days. In an extensive medical literature search, no evidence was noted to support this practice. ⋯ There is no evidence for the necessity of a bag change every 3 days at Siriraj Hospital; the urine bag can be left longer than 3 days. However, the appropriate frequency of urinary drainage bag change needs additional study because the sample size in this study does not rule out a false-negative result.
