Adaptation and validation of a portable steam sterilizer for processing intrauterine device insertion instruments and supplies in low-resource settings.

BACKGROUND

Difficulties with adequately processing intrauterine device (IUD) insertion instruments and supplies have led to use of potentially contaminated items, compromising the quality and safety of IUD insertion services in Bangladesh. A sterilization process for IUD insertion instruments and supplies by using a commercially available portable steam sterilizer was developed and validated.

METHODS

Racks provided with the sterilizer were used during sterilization of wrapped supplies (gloves and cotton balls). Metal compartments to hold insertion instruments were built to fit into the sterilizer. After sterilization, supplies were transported to rural service sites in plastic bags, whereas instruments remained in the sterilizer, which was transported in a carrying case. To validate the sterilizer, laboratory testing was conducted by using chemical and biologic indicators for steam sterilization and field testing in Bangladesh with chemical indicators.

RESULTS

Results indicated that sterilization cycles were effective in achieving sterility of IUD insertion supplies and instruments at sterility assurance levels of 10(-5) and 10(-6), respectively.

CONCLUSIONS

Use of this sterilizer for IUD insertion supplies and instruments will improve the quality of service delivery in the Bangladesh family-planning program and has application for use in many other low-resource settings.
