The impact of a sterile processing program in Northwest Tanzania: a mixed-methods study

Area of Science:

• Healthcare worker training
• Surgical instrument sterilization
• Patient safety in low- and middle-income countries

Background:

• Inadequate training for surgical instrument sterilization poses risks to healthcare workers and patients in low- and middle-income countries.
• Sterile processing practices are critical for preventing surgical site infections and ensuring patient safety.

Purpose of the Study:

• To evaluate the impact of education and training on sterile processing practices in ten hospitals in Northwestern Tanzania.
• To assess the effectiveness of a training program on healthcare workers' knowledge and application of sterile processing best practices.

Main Methods:

• A mixed-methods study combining quantitative data (hospital assessments, participant test scores) and qualitative data (interviews).
• Pre- and post-training assessments of sterile processing practices and participant knowledge.
• Thematic analysis of interviews conducted 4 months after training completion.

Main Results:

• Training directly correlated with improved test scores and enhanced sterile processing practices, particularly in instrument cleaning.
• Significant improvements were observed in the appearance of instruments, with rusted and discolored items restored.
• Participants reported practice changes, increased motivation, confidence, and awareness of challenges and resource constraints.

Conclusions:

• Education and follow-up support for sterile processing workers increase knowledge and improve practice, thereby reducing risks.
• Further research on the impact of mentorship is needed to guide future investments in training programs.
• Enhanced sterile processing knowledge and application are vital for improving healthcare safety in resource-limited settings.
