Changes in surgical instruments detected at the Central Materials and Sterilization Center

A multicenter study

Abstract

Introduction: Surgical instruments with alterations related to punctures, stains, corrosion, and/or oxidation can cause adverse events to the patient due to reduced functionality and the presence of biofilms. Objective: To analyze changes in surgical instruments detected at the Central Materials and Sterilization Center. Methods: A multicenter, cross-sectional, descriptive, quantitative study conducted in three hospitals located in the central region of São Paulo, SP, Brazil. Researchers performed a random selection of surgical instruments in the preparation room, utilizing visual inspection aided by a magnifying glass. Furthermore, aspects related to the cleaning process of healthcare products were evaluated by the researchers. Results: A total of 900 (100.0%) surgical instruments were analyzed, of which 365 (41.0%) were identified with the presence of dots and stains, 312 (35.0%) exhibited alterations in coloration, while 133 (15.0%) contained signs of oxidation or corrosion. The type of hospital, the surgical instrument, the use of potable water, changes in water quality, and the utilization of enzymatic detergent were found to trigger modifications in instruments (p<0.05). Conclusion: This study demonstrated that surgical instruments displayed alterations that could compromise patient safety.
