Abstract

Background: To assess blood utilization practices
by evaluating the cross-match ordering and
transfusion ratio in surgical and nonsurgical patients
to avoid unnecessary transfusion and wastage of
blood.
Methods: In this prospective study patients
belonging to age of 1 year to 60 years, which were
admitted in Pediatric, Medicine, Surgery,
Gynae/OBS / Orthopaeds/ wards were included.
Cross-matched to transfusion ratio (C/T ratio),
Transfusion probability (%) and Transfusion Index
(Ti) for each of these patients was performed during
the study period. C/T ratio is used as a measure of
the efficiency of blood ordering practice. It should
ideally be between 2 and 2.5. We compared our
results with the ideal.
Results: Requests from 2800 patients were sent to
prepare 3547 cross matched units. Of these, 2723
units were transfused. Overall C/T was 1.3, %T
76.7%,Ti 0.9. Of the total cross match requested
44.4% were requested by surgical department
including Gynae/OBS, Urology, Neurosurgery,
Orthopeads and General surgeries. Out of all
surgical departments C/T of Gynae/OBS was 2.5% &
of all other surgical departments was 1.7% &Ti o.4.
C/T ratio of nonsurgical patients was 1.09.
Conclusion: Overall blood utilization was
encouraging, but excessive cross-matching with
minimal transfusion practice was observed in
Gynae/OBS patients which can be minimized by
considering transfusion triggers before requesting
cross-match.
