“…Over 800 million units of blood are collected worldwide each year, but only 38% of these are collected in developing countries. [1][2][3][4][5][6][7] Recruiting more blood donors is thus crucial to ensuring a clinical blood supply. However, many first-time donors, especially younger donors, often lack knowledge about blood donation and experience discomfort during the process, including dizziness, sweating, and pallor, which are collectively referred to as the vasovagal response (VVR).…”

Objective Vasovagal reaction (VVR) is an adverse reaction to blood donation. Applied muscle tension (AMT) has been reported to reduce the probability of VVR during blood donation; however, the results have been controversial. We therefore conducted a meta-analysis to systematically evaluate the effect of AMT in reducing VVR. Methods We searched six major databases using “applied muscle tension” and “blood donation-related vasovagal response” as keywords. Relevant articles published in English or Chinese between 1 January 2000 and 30 June 2021 were included in the analysis. The quality of the included articles was evaluated and publication bias was assessed by forest and funnel plots and by Egger's test. Results Fifty-one articles were identified, of which six were included according to the pre-defined inclusion and exclusion criteria. A fixed-effects model was adopted for effect size combination and revealed a relative risk of 0.52 (95% confidence interval 0.40 to 0.67). The AMT group was superior to the control in terms of VVR prevention. A funnel plot and Egger's test suggested that the findings were accurate and reliable with low publication bias. Conclusion AMT could effectively reduce VVR during blood donation. Further multicenter studies with large sample sizes are needed to confirm these results.

BACKGROUND Social media platforms have demonstrated significant potential in influencing behaviors and have become the cornerstone for many public health and agency efforts. Blood collection agencies have embraced social media for the recruitment and retention of donors, as well as to encourage donation-related behaviors. Regular day-to-day social media status updates constitute a large part of the communication strategies employed by blood banks. OBJECTIVE Despite the promise of social media for behavior change, the evidence for the persuasive effects of day-to-day social media status updates remains scant, not only in the realm of blood donation, but across all health domains. We therefore examine long term attitudinal and behavioral outcomes to understand the impact of organizations social media page efforts on (health) behavior. METHODS We conducted a randomized controlled trial where we invited all newly registered blood donors to participate in our study to investigate the effects of a blood bank's Facebook page on donation attitudes and behavior. Participants (N = 1,891) were randomized to either the experimental or the control group. Participants were randomly assigned either to follow a blood bank's Facebook page or not. This 2 (new Facebook followers, non-Facebook follower) x 2 (pre-measure, post-measure) mixed design with an additional observational arm (current Facebook followers, N = 415) varied between and within participants and results were measured at two and twelve months after participation. RESULTS After one year, no interaction effects (group x time) for attitudinal variables were found (attitude towards blood donation; intention to donate; attitude towards blood bank; warmth; competence; donorship contemplation; contemplating the blood bank. The experiment group was 32% more likely to have made a first donation (OR: 1.32, CI: 1.01-1.73) compared to the control group. Similarly, the experiment group made 12% more whole blood and 17% more total blood donations after one year compared to the control group (resp. IRR:1.12, CI: 1.01-1.24; IRR:1.17, CI: 1.06-1.28). CONCLUSIONS After one year, no interaction effects (group x time) for attitudinal variables were found (attitude towards blood donation; intention to donate; attitude towards blood bank; warmth; competence; donorship contemplation; contemplating the blood bank. The experiment group was 32% more likely to have made a first donation (OR: 1.32, CI: 1.01-1.73) compared to the control group. Similarly, the experiment group made 12% more whole blood and 17% more total blood donations after one year compared to the control group (resp. IRR:1.12, CI: 1.01-1.24; IRR:1.17, CI: 1.06-1.28).
