Abstract

Patients with long-term indwelling urinary catheters are at an increased risk for urinary tract infection due to bacteriuria. Catheter-associated urinary tract infections (CAUTIs) are a significant source of morbidity and mortality in long-term care facilities as well as in ambulatory patients requiring long-term catheterization. There is increased interest in the financial impact of CAUTI as Medicare no longer provides reimbursement for nosocomial CAUTIs. Ascending bacteria may in part enter the closed drainage system when the patient switches between leg and night collection bags. In an attempt to reduce this ascent, a double valve lock-out system was devised that maintains a closed system during bag exchange. The concept is introduced and CAUTIs are reviewed.

Highlights

The urinary catheter is a device that serves as a tube to mechanically drain the bladder for a variety of pathological conditions or surgical procedures
Indwelling urinary catheters have the highest risk of nosocomial infection due to the fact that they remain in the bladder for a long period of time and allow microbial colonization and invasion [1]
As of 2008, Medicare will no longer be reimbursing for Catheterassociated urinary tract infections (CAUTIs) [5]

Summary

Introduction

The urinary catheter is a device that serves as a tube to mechanically drain the bladder for a variety of pathological conditions or surgical procedures. The time was measured from the point of inoculation to the point of colonization of the drainage port, which is just proximal to the bladder model, and compared between the two sets of drainage bags They found that it took 14 days to colonize the single valve system while it took more than 21 days to colonize the double nonreturn valve system. They concluded that the double nonreturn valve increased the time necessary for bacterial colonization of the catheter, suggesting that a double nonreturn valve system is able to be used on a long term without increasing the risk of infection in a catheterized bladder model with twice daily bag emptying [13]. This paper introduces an approach to improve the integrity of the closed urinary drainage system
