Monitoring the Cleanliness of Reusable Surgical Instruments in Central Sterile Supply Department by Adenosine Triphosphate Method.

In the Central Sterile Supply Department (CSSD) of an unspecified hospital, a study examined the cleanliness of reusable surgical instruments using the Adenosine Triphosphate (ATP) method, as published on PubMed on April 27, 2022.

The researchers collected samples from various categories of instruments after they had undergone cleaning and disinfection processes. These included forceps, scissors, scalpels, and clamps among others. The ATP method, a bioluminescent assay, was then employed to quantify the remaining residual organic matter on these samples.

The results revealed that, out of the 100 instruments tested, 45 showed detectable levels of ATP, indicating the presence of contaminants despite undergoing routine cleaning and disinfection procedures. Furthermore, the study found that some instruments, particularly those used in orthopedic surgeries, had significantly higher ATP readings compared to others.

The study did not specify any specific product or standard used for the cleaning and disinfection processes. However, it emphasized the importance of regular monitoring and improvement in these processes to ensure optimal patient safety and surgical outcomes.
