Nosocomial urinary tract infections

Convenience to the hospital staff is certainly not an acceptable reason for the use of a potentially dangerous drainage tube. An indwelling urinary drainage catheter should be used only in patients who need multiple straight urinary catheterizations, develop urinary obstruction or incontinence, or are comatose and require frequent urinary output measurements. An indwelling catheter may also be needed for drainage or stenting during or following genitourinary surgery. Once it has been determined that urinary catheterization is necessary, a closed urinary drainage system catheter must be carefully and aseptically inserted by experienced hospital personnel after careful preparation. The closed drainage system must be meticulously maintained throughout the patient's hospitalization and catheterization. After the catheter is removed, a urinary culture should be performed to identify any postcatheter infection. If there is infection, the patient must be treated with antibiotics. If symptoms of a urinary tract infection, bacteremia, or sepsis ensue, treatment must be rapidly begun with antibiotics as appropriate on the basis of drug sensitivity testing. These techniques will not eliminate bacteriuria associated with urinary drainage catheters. However, they will reduce the incidence, morbidity, and mortality associated with urinary catheterization.
