To evaluate the use of a computerized physician order entry (CPOE) protocol on manual red blood cell (RBC) exchange transfusion in critically ill children with sickle cell disease.
We conducted a retrospective study of children with sickle cell disease who received a manual RBC exchange transfusion before (2001 to 2008, n=22) and after (2008 to 2009, n=11) implementation of a CPOE protocol. Outcomes included compliance with protocol, percentage reduction in sickle hemoglobin, and peak hemoglobin during exchange.
Compliance with the manual exchange protocol improved after introduction of CPOE (pre-CPOE: 20 protocol violations vs. post-CPOE: 3 violations, P=0.02). Percentage reduction in sickle hemoglobin also improved (pre-CPOE: 55% vs. post-CPOE: 70%, P=0.04), whereas peak hemoglobin during RBC exchange was similar (pre-CPOE: 12.0 g/dL vs. post-CPOE: 11.5 g/dL, P=0.25). However, hemoglobin levels after the mean of 7 hours of exchange were significantly higher pre-CPOE (pre-CPOE: 11.5 g/dL vs. post-CPOE: 10.5 g/dL, P=0.006).
Use of CPOE for manual RBC exchange transfusion in children is associated with improved protocol compliance, improved reduction of sickle hemoglobin, and better maintenance of hemoglobin levels in a goal range during prolonged exchanges.
