Abstract

Objective: To explore the application effect of lean management in improving the quality of outpatient blood collection services.

Methods: For this study, a total of 146,907 patients whose blood was sampled by outpatient services between April 2020 and September 2020 were selected. We analyzed the influence of various factors on the waiting time and satisfaction levels of the patients for blood collection and eliminated confounders based on the results of the analysis. Lean management for the outpatient blood collection service was implemented in July 2020. Thus, the 38,275 cases sampled on weekday mornings between April and June 2020 were selected as the ordinary management group, while the 39,473 cases sampled on weekday mornings between July and September 2020 belonged to the lean management group. Finally, the changes in waiting time and the satisfaction levels of the patients were evaluated.

Results: The age and gender of the patients and the length of service of the staff, who administered blood collection had a negligible effect on the waiting time (Z=-1.243, P=0.418; Z=-1.569, P=0.389; Z = -1.062, P= 0.563), while there was a statistical difference in the waiting time between different days and different sessions (Z = -2.581, P = 0.013 and Z = -4.672, P < 0.001). We also found that the length of service of blood collection staff, day, session, and age and gender of patients did not have a meaningful effect on patient satisfaction (P > 0.05). Overall, the median waiting time of outpatients decreased from 22 min to 13 min after the implementation of lean management (Z =10.522, P < 0.001), while the satisfaction level of outpatients increased from 95.37% to 98.33% (χ ² = 559.580, P < 0.001).

Conclusion: The application of lean management can significantly shorten outpatient waiting time for blood collection, improve patients satisfaction levels, and enhance the overall patient experience. Thus, lean management can significantly improve the service quality of outpatient blood collection.
