Description of intervention(s) / exposure
Intervention: Applied Muscle Tension (AMT)

Applied Muscle Tension is a behaviour therapy technique, which has been found to increase cerebral blood flow and blood pressure (BP). The technique involves tensing and relaxing the large muscles (hamstrings, abdominal muscles) in the body

15 Australian Blood Donor Centres will be randomised in a step wedged fashion to commence a phased roll out of AMT during all eligible plasma donations at 2 weekly intervals, over a period of approximately 30 weeks.

Donors donating during the in the intervention phases will be instructed using written materials and face to face instruction from donor centre staff to: 1) cross their legs, 2) squeeze their inner thigh and abdominal muscles, and 3) stretch their ankles. They will be asked to hold this position for 5 seconds, then relax for 5 seconds, repeating the cycle 5 times, and then switch legs.

The average plasma donation time is 45minutes. All intervention phase donors will be instructed to perform AMT at different time points during the plasma donation (Needle In, 15min & 30min after donation starts, Needle out and before getting off the donor chair). Compliance to AMT will be by direct observation by Donor Centre staff and a post donation donor survey.
Intervention code [1] 317119 0
Prevention
Comparator / control treatment
Standard of care will be used as the control for the study. Standard of care is for staff to encourage donors to use AMT before getting up from the donation couch only, in accordance with current practice for the prevention of orthostatic intolerance.
Control group
Active

Outcomes
Primary outcome [1] 323579 0
Difference between intervention and control groups in the composite rates of phlebotomist-registered presyncope and syncopal reactions.

Data will be obtained through linkage to Lifeblood National Blood Management System donor records
Timepoint [1] 323579 0
72 hours after cessation of plasma donation
Primary outcome [2] 323580 0
Sustainability of the implementation of Applied Muscle tension during plasma donations. This will be evaluated by mixed approach of both qualitative and quantitative methods including staff and donors knowledge and satisfaction of AMT used during a plasma donation to identify if the intervention is still being used as intended.

One-on one open ended audio recorded phone interviews will be conducted with a sample of staff members, and a study specific survey will be sent to all participating staff members. Donors will also receive a study specific survey to complete
Timepoint [2] 323580 0
Staff knowledge and feedback will be assessed via study-specific survey at the end of the 30 week trial and 6 months after the completion of the 30 week trial, Staff satisfaction will also be assessed with a sample of staff in one on one interviews or focus groups (audio recorded) commencing at 3 months after the completion of the 30 week trial,
Secondary outcome [1] 382262 0
Difference between intervention and control groups in the number of donor adverse events (AEs). Known adverse events include phlebotomy injures (e.g.: haematoma), localised infections and citrate reactions. AEs will be recorded either directly by donor centre staff present during the donation or reported directly by the donor post donation to our national call centre.
Timepoint [1] 382262 0
Immediately after blood donation or within 24 hours after donation if a delayed reaction occurs
Secondary outcome [2] 382263 0
Difference between intervention and control groups in Blood Donor Reaction Inventory (BDRI) scores a participant reported outcome

Donors will be assessed on how they feel post donation using the BDRI's 6 item Likert Scale 0-5,
Timepoint [2] 382263 0
within 72 hours post cessation of donation
Secondary outcome [3] 382277 0
Difference between intervention and control group scores of the Blood Donor Self Efficacy Scale a participant reported outcome

Donors will assessed on 8 items on a Likert Scale 1-7 as part of the Blood Donor Self Efficacy scale (France CR, Montalva R, France JL, Trost Z. Enhancing attitudes and intentions in prospective blood donors: evaluation of a new donor recruitment brochure. Transfusion. 2008;48(3):526-30.)
Timepoint [3] 382277 0
within 72 hours post cessation of donation
Secondary outcome [4] 382278 0
Difference between intervention and control groups in length of time taken to complete apheresis procedure. The time taken for each collection is measured from the start of the donation by the automated blood collection system until completion or early termination and recorded by the phlebotomists in the donors electronic record
Timepoint [4] 382278 0
from start to finish of the blood donation
Secondary outcome [5] 382279 0
Difference between intervention and control groups in sub optimal/ underweight collections. The weight of collections are measured at the end of the donation by the automated blood collection system and recorded by the phlebotomists in the donors electronic record
Timepoint [5] 382279 0
Immediately after blood donation
Secondary outcome [6] 382281 0
Difference between intervention and control groups in retention rates (rates of return for subsequent donations). This will be assessed by using Lifebloods National Blood Management Systems donation records
Timepoint [6] 382281 0
4 months from initial donation
