Abstract: Objective: To improve the collection, storage and delivery quality of venous blood specimens, shorten the time for delivering specimens, and reduce the incidence of unqualified specimens. Methods: The nursing department collaborated with medical affairs department, laboratory department, logistics management centre, clinical departments, and information department. The core focused on specimen collection and storage quality, barcode quality, collection and storage method quality, specimen delivery quality, data analysis, and continuous improvement. Based on the hospital's holographic view system of patients, this study established a workflow for venous blood specimen management before the test, consisting of specimen trajectory display, problem information warning, feedback for clinical processing, management information push, and continuous quality improvement. A quality management pathway for venous blood specimens before the test was constructed, which consisted of three modules. The effectiveness of the pathway was evaluated after a 3-month application period. Results: In comparison to the same period last year, after the implementation of the quality management pathway for venous blood specimens before the test, the rate of unqualified venous blood specimens decreased from 0.31‰ to 0.19‰. The rate of unqualified specimens due to improper collection and storage decreased from 0.17‰ to 0.07‰. The turnaround time was shortened, and the delay rate of specimen transportation decreased, and the differences were statistically significant (P<0.05). Conclusion: The quality management pathway for venous blood specimens before the test based on the holographic view system of patients achieved tracing and management of the entire specimen process, providing a convenient query channel for clinical medical staff, reducing communication time costs, effectively improving the quality of venous blood specimens before the test, and reducing the rate of unqualified specimens.
