Methods: A qualitative study developed with 12 nurses from hospitals in the South and Southeast Brazilian regions, with data collected in March 2021 through online interviews. Bardin's content analysis was performed with the support of the IRaMuTeQ software.
Results: The interpretations were classified considering the following aspects: indirect care provided by Central Sterile Supply Departments (27.16%), low visibility of Central Sterile Supply Departments for patient safety (26.92%), difficulty in internal communication (30.69%) and difficulties learning from errors and fair culture (15.23%).
