The instruments employed by hospitals participating in the basic study were mainly from various manufacturers such as Sysmex, Stago, Werfen, Sekisui, Beckman, Mindray, Succeeder, BSBE, and Rayto, involving 96 instruments, of which 11 hospitals used instruments from two manufacturers, with the use of each brand of blood coagulation analyzers shown in Fig. 4. As shown from the figure, among the hospitals participating in the study, the proportion of hospitals using Sysmex instruments was 39%, the proportion of those using Mindray was 23%, followed by 14% for Succeeder and 7% for BSBE, indicating that the domestic instruments have been recognized by hospitals to a certain extent. Among the 80 hospitals participating in the study, 75 hospitals had used the corresponding matching reagents, while 5 hospitals had chosen reagents of non-instrument brands; in terms of the selection of consumables, 74 hospitals used matching consumables, indicating that these hospitals preferred to choose the original matching reagents and consumables, with the reason being that the selection of matching reagents and consumables could largely ensure the suitability between the items and the instruments. However, the use of non-instrument brand reagents and consumables signifies that due to the cost pressure of imported reagents and the advocacy of national policies, some hospitals are prepared to choose manufacturers with reliable quality and cost advantages, such as Shanghai Sun Biotech and BSBE.
