Objective To discuss the practical effect of process reengineering in PICC reengineer-ing management. Methods PICC process was analyzed and the original unreasonable process was reengineered. The number of cases for tube insertion, success rate of paracentesis, incidence rate of compli-cations and patients satisfaction degree with nursing before and after implementing process reengineering were compared nsing χ2 test. Results After the promotion for clinical use of PICC, the numbers of cases for tube insertion, success rate of paracentesis and incidence rate of complication evidently decreased, pa-tients satisfaction degree increased greatly. Conclusions Process reengineering makes the PICC man-agement more standard, safe and highly effective.
