To be honest I am not an expert on this, but here is something I copy and pasted about PABD.
"Pre-operative autologous blood donation (PABD) aims to provide a supply of safe blood for patients undergoing surgery who might need a blood transfusion while at the same time increasing the patient's total red blood cell (RBC) mass due to the PABD-induced stimulation of erythropoiesis before scheduled elective surgery.
Meta-analyses on PABD have shown that this practice: (i) reduces the use of allogeneic blood transfusion by 63%, (ii) increases overall RBC transfusions (i.e. allogeneic and autologous RBC units) by 30%, and (iii) causes a decline of patients' haemoglobin (Hb) concentration by more than 1 g/dL from before commencing PABD to immediately prior to surgery
The wastage of unneeded PABD units varied from 18% to above 50%"
And from UpToDate - a medical wikipedia doctors use "We believe that PAD programs currently have marginal value and cost effectiveness"
Okay, I was curious as a frequent blood donor but someone who also has major issues with Canadian Blood Services as an organization. I'd really love nothing more than to have something to give them a hard time about.
