The study examines how inadequate preprocessing of reusable surgical instruments can contribute to biofilm formation, incomplete cleaning and healthcare-associated infections. Conducted at a tertiary hospital, the research introduced an evidence-based preprocessing protocol covering immediate removal of visible contaminants, keeping instruments moist, appropriate cleaning agents, safe transportation, instrument-specific handling and standardized staff training. Following implementation, the rate of instruments requiring initial re-cleaning fell significantly from 0.67% to 0.085%, while staff knowledge assessment scores improved from 58.06 to 95.83 out of 100.
The findings highlight that effective infection prevention depends not only on subsequent disinfection and sterilization but also on the quality of cleaning and preprocessing that takes place beforehand. The study emphasizes the importance of standardized procedures, appropriate cleaning practices, trained personnel and continuous quality monitoring in healthcare facilities. By addressing contamination at the earliest stage of instrument reprocessing, healthcare institutions can improve cleaning efficiency, reduce repeated handling, protect delicate instruments and strengthen overall infection prevention measures.
