Variability in catheter microwave sterilization techniques in a single clinic population

Area of Science:

• Urology
• Infection Control
• Medical Device Sterilization

Background:

• Clean intermittent catheterization (CIC) is a common procedure for bladder management.
• Home sterilization of urinary catheters is crucial for preventing infections.
• Microwave sterilization is a frequently used method by patients for home catheter care.

Purpose of the Study:

• To assess the microwave sterilization techniques employed by patients undergoing clean intermittent catheterization.
• To identify variations and potential issues in patient-practiced microwave sterilization methods.

Main Methods:

• A two-part survey was administered to patients performing CIC.
• The initial survey gathered data on urinary catheter use and home sterilization practices.
• A follow-up survey specifically assessed microwave sterilization techniques in detail.

Main Results:

• High return rates for both initial (64%) and follow-up (85%) surveys were achieved.
• Most respondents (75%) have used CIC for over 5 years, with 80% performing it 4-5 times daily.
• Significant variation in sterilization frequency was noted (daily to less than weekly).
• While 71% reported no difficulty, 63% experienced catheter melting during microwaving.
• Practices regarding rotation tables, water usage, microwave wattage, time, and power settings showed considerable diversity.

Conclusions:

• Substantial variability exists in patient-performed microwave catheter sterilization techniques, even with uniform instructions.
• The impact of these diverse practices on effective sterilization remains unclear.
• Further research is needed to establish optimal and safe microwave sterilization protocols for home use.
