“…Another trial by Mondy et al used a vein suitability scoring in young whole blood donors for predicting phlebotomy outcomes and demonstrated a very low failure rate (<1%) in donors with the highest vein score of 12 and most phlebotomy failures occurred (63%) with vein score of less than 7.5. Only one study in apheresis donors where VST was assessed for phlebotomy/procedure outcomes showed a score difference between successful and failed phlebotomy outcomes where the median scores were 9 and 8, which was statistically significant, unlike in our study 11 …”

“…Only one study in apheresis donors where VST was assessed for phlebotomy/ procedure outcomes showed a score difference between successful and failed phlebotomy outcomes where the median scores were 9 and 8, which was statistically significant, unlike in our study. 11 Though there was no statistically significant correlation between vein score and LFA, it was noted that in donors with vein scores of 0-7, 84% had no LFA, and only 5% had continuous LFA. Also, the percentage of donors with no LFA was lesser in the 10-12 group compared to the group of 0-7 and 8-9 scores.…”

IntroductionDonor vein assessment for the selection of good quality veins is crucial for a successful apheresis procedure. This study intends to find out the effectiveness of a vein assessment scoring tool (VST) used and found to be effective in selecting whole blood donors to reduce the difficulty in identifying good quality veins for the plateletpheresis procedure.Materials and methodsThis was a prospective observational study on platelet apheresis donors with the application of a VST consisting of three vein descriptor parameters (vein visibility, vein palpability, and vein size) with 5 Likert‐type responses constituting a score of 0–12 for each arm. Two vein assessors independently evaluated the vein in both arms and marked their responses blinded from each other as well from the principal investigator. The scores were then calculated and analyzed at the end of the study for their association with phlebotomy and procedural outcomes.ResultsA total of 190 donors were recruited. The mean scores for the arms with successful and failed phlebotomy were 9.1 and 9.4 (SD 2.3), respectively. The intra‐class correlation Alpha Cronbach value was 0.834 and 0.837 for total scoring in the left arm and right arm, respectively, between the two assessors. Scores neither showed a correlation with other outcomes like low flow alarms, hematoma formation, number of phlebotomy attempts, and procedure completion.ConclusionThe study showed that the vein score tool did not truly predict the phlebotomy outcome in apheresis donors, though there was a good degree of inter‐assessor reliability.
