Blood Utilization Review Using Transfusion Indices in a Tertiary Care Center: A Retrospective Observational Study.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background Excessive preoperative blood requisition often results in non-utilization, aging, and wastage of blood units and resources. Transfusion indices help assess the efficiency of the blood requisition process. Hence, this study aimed to analyze blood utilization patterns using transfusion indices across various departments in a tertiary care center. Methodology This study employed a retrospective, observational design, utilizing blood bank records collected over a one-year period from April 1, 2023, to March 31, 2024. A total of 5,881 patients were analyzed. The primary aim was to evaluate blood utilization efficiency by calculating key transfusion indices based on the crossmatching and transfusion of packed red blood cells (PRBCs). These indices included the crossmatch-to-transfusion (C/T) ratio, transfusion probability (TP), and transfusion index (TI). Results Out of 6,694 blood requisitions received during the study period, 5,881 patients underwent PRBC transfusions. A total of 11,894 PRBC units were crossmatched, of which 7,759 (65.23%) units were ultimately transfused. Transfusion indices demonstrated notable variations across different departments. The General Surgery Department recorded the highest C/T ratio at 2.05, while Hemato-oncology and Radiotherapy achieved the highest TP of 96%. In contrast, Dermatology reported the lowest TP at 74%. Gastro-surgery stood out with the highest TI of 2.47. Despite these differences, all departments operated within the established acceptable transfusion thresholds, maintaining C/T ratios below 2.5, TP values above 30%, and TI levels exceeding 0.5. Conclusions Departments with outlier indices should adopt restrictive transfusion practices. Educational programs and department-specific guidelines can optimize blood utilization, reducing unnecessary transfusions, costs, and resource consumption.
