Review of Clinical Practices on Reducing PICC Catheter Infection Rates through Quality Control Circles (QCC) Activities

Peripherally Inserted Central Venous Catheters (PICC) are now widely used in clinical nursing. However, catheter-related infections have become a major concern in clinical practice. This review summarizes the application of Quality Control Circle (QCC) activities in reducing PICC infection rates and finds that QCC activities play a significant role in improving nurses' competencies, standardizing operating procedures, enhancing patient education, optimizing environmental materials and so on, thereby effectively reducing infection rates. Clinical data show that QCC has an outstanding application effects in groups such as cancer patients, neonatal patients, and leukemia patients, with an improvement in infection rates over 50%. Moreover, QCC activities enhance nurses' professional competence and help establish a systematic infection prevention and control framework. The QCC model provides a standardized improvement pathway for clinical catheter management and holds significant guiding value.
