BACKGROUND: Surgical site infections can cause significant morbidity requiring lengthy antimicrobial treatment. Infections have been linked to surgical instruments with retained tissue and foreign debris, as the presence of blood or soil interferes with sterilization effectiveness. This study aimed to determine the prevalence of visible soil or debris inside instruments and evaluate the impact of recleaning efforts.
METHODS: Borescopes were used to inspect lumens of instruments used for orthopedic, neurologic, or ear-nose-throat procedures. Whenever visible soil or debris was observed, the instrument was recleaned up to 3 times and reinspected to assess the impact of additional cleaning.
RESULTS: Researchers performed 117 inspections (40 unique instruments, 77 reinspections). All instruments had complex lumens that impede access by brushes. Debris and discoloration or residues were observed inside 100% of instruments, with rusty patches in 95%. Some soil was removed by recleaning, but visible soil remained in most lumens and fragments of lint or brush bristles were visible upon repeat inspection.
CONCLUSIONS: Cleaning in accordance with the manufacturer's instructions was not effective for lumened surgical instruments. Solutions will require collaboration between infection prevention, sterile processing, and manufacturers to evaluate risk and develop strategies for improving processing outcomes.
