Decontamination of urinary bags for rehabilitation patients

Patients with neurologic injuries frequently have permanent indwelling or external catheters connected to disposable urinary bags. These patients routinely disconnect the bed bag during the day and apply a leg bag which can be concealed under their clothes. In our rehabilitation unit, both bags are discarded daily. This study investigated the possibility of safely reusing bed and leg bags. The procedure involved decontamination of the bags using 180 ml of a 1% solution of sodium hypochlorite. Initially, discarded bed and leg bags were decontaminated in the lab to ensure effectiveness of the procedure. Next, 22 patients reused their bed and leg bags with daily decontamination by the rehabilitation nursing staff. These bags were reused for two to eight days. Cultures of 137 bags were obtained to evaluate the technique. All cultures were negative. Baseline urine cultures for both time periods showed no significant difference in rates of bacteriuria. The potential savings for one year on our rehabilitation unit, with an average of 12 catheterized patients, would be approximately $39,000. Although this methodology conflicts with thoughts about not reusing disposable products, we have shown that the procedure can be done safely in rehabilitation patients and it is easy and inexpensive.
