Abstract：Objective Based on real world data, to analyze the cost of hemostatic materials for patients in diagnosis related groups
(DRG) in a hospital over a period of time, to support for the management and control of such consumables. Methods The data from
a certain DRG group in the medical record data of H hospital from January to October 2022 was selected, and Spearman, Mann
Whitney U, and Kruskal-Wallis statistical methods were used to analyze the use of hemostatic materials in patients with different
surgical procedures and departments under this DRG group, as well as the differences in cost effectiveness and clinical efficacy of
using different types of hemostatic materials. Results The cost of hemostatic materials was positively correlated with hospitalization
cost. The cost of hemostatic materials varied with different surgical types. In the selected key operations, there were differences in
the cost of hemostatic materials between the two departments of four kinds of operations, and differences in the cost of hemostatic
materials between different diagnosis and treatment groups of two kinds of operations. The average cost of the six kinds of operations
in the DRG group was related to the utilization rate of the two hemostatic materials with the lowest unit price and the highest.
Compared with other hemostatic materials with the highest unit price, in terms of cost effect, the per capita hospitalization cost was
higher in some surgeries, and the difference in hospitalization cost was statistically significant, but there was no difference in clinical
effect. Conclusion The departments, operation methods, diagnosis and treatment groups and product categories that should be
focused on for the control of such consumables are clarified. In addition, according to the research results, management suggestions is
proposed from multiple dimensions, which can be used for reference to standardize clinical consumption behavior and fine control of
hemostatic materials.
