2021 Cardiac Surgery Annual Report

Length of Stay (LOS)

Transfusion rate by procedure type and blood product type Data is collected for each specific blood product – red blood cells (RBC), platelets, cryoprecipitate (cryo) and fresh frozen plasma (FFP). Table 6 shows the transfusion rate for each blood product by procedure type in 2021.

• Total LOS = from hospital admission to hospital discharge • Pre-operative LOS = from hospital admission to date of operation. This includes only the time before surgery at RNSH, and does not include inpatient waiting time at outside hospitals • Post-operative ICU LOS = from date of operation to end ICU care • Post-operative LOS = from date of operation to discharge from ICU
