ABSTRACT
BACKGROUND:
This study aims to determine the phlebotomy and procedural outcomes using a vein assessment tool (VAT) in Double Dose Platelet (DDP) collections by apheresis.METHODS:
VAT was based on assessing vein visibility, palpation and size with maximum score of 12 and the least being 0 and the scores were graded as adequate and inadequate. A vein-viewer was used for studying cubital vein patterns (type 1-5). Phlebotomy outcome was defined based on need for re-puncture. Procedural outcomes in terms of target yield attained and RBC reinfusion completed. Chi square test and Mann- Whitney U test were used to assess the vein score and pattern against phlebotomy and procedural outcome.RESULTS:
Out of 200 DDP collections, the phlebotomy was successful in 88 % with good procedural outcome in 94 % donations. The cut off in VAT scores for successful phlebotomy was ≥8 (AUC 70 %). Median vein scores of the arm selected for phlebotomy was 9 and graded adequate in 154 (77 %) donations.Odds for successful phlebotomy was 3.7 times higher when donors had an adequate VAT grades(p = 0.003). Procedural outcomes was favourable when at least one arm had adequate VAT grade when compared to both arms being inadequate (98 % vs 82 %; p < 0.001). Phlebotomy failure was more with first time apheresis donors than repeat apheresis donors (p = 0.014).CONCLUSION:
This study indicated that a VAT score with a cut off of ≥8 had better phlebotomy and procedural outcomes in DDP collections and that donor with at least one arm having the VAT score of ≥8 are preferred for DDP collections.Palavras-chave
