Objectives And Background:
There are few studies of quality interventions to mitigate the risk of transfusion-associated circulatory overload (TACO). Our aim was to reduce TACO risk in patients admitted to internal medicine at our hospital, by addressing gaps in transfusion practice.
Materials And Methods:
A 3-month baseline audit of red blood cell (RBC) transfusion orders was conducted. An intervention consisting of a transfusion order set and physician checklist was developed and implemented based on identified gaps, followed by a 3-month post-intervention audit. Compliance with appropriateness criteria for RBC transfusion was ascertained, along with documentation of transfusion rate, diuretic usage and consent.
Results:
A total of 97 transfusion orders from 68 inpatients and 95 orders from 62 inpatients were audited in the baseline and post-intervention groups, respectively. Compliance with appropriateness criteria was similar pre- and post-intervention (87 versus 85%, P = 0·81). Specification of transfusion rate improved (84 versus 98%, P < 0·01), and diuretics were appropriately ordered more frequently for patients with TACO risk factors (37 versus 64%, P < 0·01). Timing of diuretics shifted from between or post-transfusion to pre-transfusion (35 versus 86%, P < 0·01), without increases in hypokalemia or acute kidney injury. No case of TACO was observed during the study. Documentation of specific risks discussed during consent discussion improved (4 versus 23%, P < 0·01).
Conclusion:
A checklist and order set are tools that can improve the quality of transfusion orders by increasing the judicious use of pre-transfusion diuretics and augmenting the specification of transfusion rate. These interventions could be adapted to electronic order formats to improve transfusion safety.
