“…This could potentially be attributed to staff targeting male donors, who they perceive as being more suited to plasmapheresis, or to males reporting a greater number of risky behaviours, such as travel, which prevent donors from giving whole blood. Similarly, Hirani and colleagues [11] found poorer vein suitability for blood donation among females compared to males. Therefore, more males may have been converted to plasma in our cohort based on vein quality.…”

Offering new and returned donors the option to give plasma: implications for donor retention and donor adverse events

Background and Objectives In 2018, Australian Red Cross Lifeblood changed its plasmapheresis eligibility criteria to allow donors to donate plasma without the requirement of a prior successful whole blood donation. This study evaluated the impact of this policy change on donor retention and donor safety. Materials and Methods All donors who had attempted to give their first plasma or whole blood donation from January to June 2018 were included in this retrospective cohort study. Donor characteristics and adverse events were analysed for this index donation, and the cohort was followed for 18 months to analyse time to return, subsequent donation frequency and predictors of return. Results Male and younger donors provided a significantly greater proportion of first donation plasma than females and older donors. New donors who gave plasma had the highest rate of donor adverse events, including vasovagal reactions and phlebotomy injuries. Nevertheless, donor retention was not affected, with more new donors returning and at a greater subsequent donation frequency after a plasma donation compared to new donors donating whole blood. Firsttime plasma donors who had previously donated whole blood, however, had greater and quicker rates of return, and more subsequent donations. Conclusion Offering new donors the option to give plasma had a positive effect on donor return and subsequent donation frequency. Removing the requirement of a prior whole blood donation is a viable way to increase plasma collections although the combined effect of new donor status and plasmapheresis procedure on adverse event risk needs to be considered.

“…13 In the study by Hirani et al mentioned above, it was shown that when experienced staff members were compared with staff having experience of <6 months, the vein score had a good correlation with phlebotomy outcome. 8 It is expected to help in reducing subjectivity with the development of additional training and supporting training materials.…”

“…As of date, very little literature is available for assessing vein suitability among apheresis donors, although studies on vein assessment for whole blood donors using vein assessment scoring tools (VST) show better phlebotomy outcome. 8 Ideally, the vein score assessment system would generate a consistent result in assessing vein suitability when used by any phlebotomist, irrespective of their experience or other variables in phlebotomy. This study intends to find out the effectiveness of a VST used and found to be effective in selecting whole blood donors in reducing the difficulty in identifying good quality veins for the plateletpheresis procedure.…”

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.

“…The majority of individual WAHVAC variables ( n = 17, 85.0%; and n = 16, 80.0%, respectively) also had excellent agreement for interrater and test–retest reliability (adjusted κ statistics >0.75). The WAHVAC has an advantage over other instruments that assess peripheral intravenous cannulation complexity for the insertion of catheters (Civetta et al, 2019; Hirani et al, 2019; Pagnutti et al, 2016; Van Loon et al, 2019) as the variables on the instrument are specific to HD VA.…”

“…Instruments that assess access complexity for the related but different scenario of peripheral intravenous catheter insertion are common (Civetta et al, 2019; Hirani et al, 2019; Pagnutti et al, 2016; Van Loon et al, 2019). There is currently no “gold standard” for grading the complexity of HD VA and no published instrument to assess HD VA complexity.…”

Background: The Western Australian Haemodialysis Vascular Access Classification instrument was developed to classify the cannulation complexity of the arteriovenous fistula or arteriovenous graft as simple, challenging, or complex. Although the instrument was developed by experts in haemodialysis nursing, the instrument had not undergone formal validity or reliability testing. Objectives: Evaluate the Western Australian Haemodialysis Vascular Access Classification instrument for content validity, interrater and test-retest reliability. Design: Prospective cohort study. Participants: Content validity was assessed by haemodialysis nursing experts (n = 8). The reliability testing occurred in one in-centre and one satellite haemodialysis unit in Western Australia from September to November 2019. Reliability testing was performed by 38 haemodialysis nurses in 67 patients receiving haemodialysis and 247 episodes of cannulation. Measurements: Interrater and test-retest reliability assessment was conducted using κ, adjusted κ, Bland-Altman plots, intraclass correlation coefficient and Pearson's correlation coefficient. Results: The final version of the instrument (n = 20 items) had individual item-level content validity indices ranging from 0.625 to 1.00 with a scale-level content validity index of 0.89. For both interrater (n = 172 pairs) and test-retest (n = 101 pairs), most individual variables had excellent adjusted κ (n = 33 variables), some fair to good agreement (n = 6 variables) and one variable with poor agreement. The classification of simple, challenging and complex demonstrated adjusted κ of fair to good, to excellent agreement for interrater reliability with lower levels of agreement for test-retest reliability.Conclusions: This instrument may be used to match a competency-assessed nurse to perform the cannulation thereby minimising the risk of missed cannulation and trauma.
