Balancing Costs and Clinical Outcomes: A Cost-Effectiveness Study of PICC Types Across Chinese Healthcare Settings

Long-term intravenous therapies often necessitate the use of peripherally inserted central catheters (PICCs). Antimicrobial-coated PICCs have been introduced to minimize central line-associated bloodstream infections (CLABSIs). A decision-analytic cost-effectiveness model was developed from a societal perspective, utilizing real-world data concerning PICC-related complications and costs from Class 3A hospitals and community hospital settings in China. The analysis compared the quality-adjusted life years (QALYs) for patients receiving antimicrobial-coated PICCs versus standard PICCs, with catheter-associated costs included. Incremental cost-effectiveness ratios (ICERs) were calculated in Chinese Yuan (CNY) per QALY gained. Patients with antimicrobial-coated PICCs experienced slightly fewer complication-related events, leading to significantly lower costs for managing complications. In the Class 3A hospital setting, the average total cost per patient was lower with antimicrobial-coated PICCs (CNY 62,800) compared to standard PICCs (CNY 102,900), primarily due to the reduced expenses for treating CLABSIs and related unknown fever. The ICER demonstrated that the coated PICC was the strongest option, showing a negative ICER (cost-saving of approximately CNY 4 million per QALY gained in the base-case Class 3A hospital scenario). In community hospital care scenarios, the cost advantage of antimicrobial-coated PICCs remained. Thus, the antimicrobial-coated PICC strategy was cost-saving, providing equal or improved health outcomes at lower costs in China’s medical center and community hospitals, making it a more efficient choice for long-term vascular access.
