How to screen patients admitted due to trauma and query blood transfusion information?

[xujiameng]

Hi,
I am using the HIRID database to screen patients admitted for trauma, but the database does not seem to contain information about the diagnosis of admission or the type of treatment the patient receives. Can I screen patients admitted to the hospital for trauma through other channels?

In addition, by searching keywords, I retrieved the following IDs related to blood transfusion in the table:
1000050, 1000744 (Transfusion of plasma (FFP))
1000100, 1000743 (Intravenous blood transfusion of packed cells)
1000245, 1000201 (Platelet transfusion)

But` I am not sure if I have missed other fluids related to blood transfusion.
