None of the algorithms to predict blood loss and
transfusion needs in TJA proposed so far7,22-26 appear to
be widely effective16,27. According to our data, the simple
measurement of basal haemoglobin concentration could
be sufficient to effectively reduce non-used autologous
and allogeneic blood units, as already suggested
elsewhere28,29. Specifically, if autologous blood were
requested only for patients with a baseline haemoglobin
concentration below a threshold of 14.65 g/dL, a total
of 83 requested and non-used allogeneic blood units
(31.7%) would have been saved, while only one patient
(0.4%, THA) would have needed an emergency request
for blood. The threshold calculated for the PABD
patients was higher (15.85 g/dL). Use of this threshold
trigger in blood transfusion decision-making would
have saved only 9.5% of discarded units (15 out of
157), while two patients (1.1%) would have needed an
emergency request for blood units. Furthermore, there
appears no reason to adopt different threshold triggers
for PABD+PCS and PCS only patients, as their starting
conditions are identical.
