Abstract:

Objective: To investigate the relationship between the change of the bag and urinary tract infections, in order to reduce
the incidence of urinary tract infection. Methods: The indwelling catheter patients and (or) family members were told about the
research purpose and methods. The selection of patients and family members into the group were fully respected. The observation group
did not replace the drainage bag,while the control group changed drainage bag 7 d according to the prescription. The urinary specimens
of two groups of patients with indwelling catheter were collected and sent for bacterial culture. Results: The difference of the infection
rate between the control group and the observation group was statistically significant (P < 0.05). Conclusion: Not changing the
drainage bag can reduce urinary tract infection.

Key words: urinary tract infection, indwelling catheter, drainage bag
