The study was conducted in two blood transfusion centers and 282 people over the age of 18 participated. It was important to understand whether augmented reality could help reduce anxiety during the blood draw.

Participants in the experiment were asked to use the Microsoft HoloLens 2 AR headset with a special application developed by Abbott and American Blood Banks. The created augmented reality avatar focuses the donor’s attention on selecting and planting seeds that grow into colorful trees and flowers on the environment and equipment. Relaxing music plays in the background and eye movements are enough to check it out. Before and after the session, study participants filled out special questionnaires, and at the end of the study, medical staff also filled out their questionnaires.

The results were impressive. According to them, 84% of donors decided to try an unfamiliar AR headset because it was “interesting,” “fun,” “cool,” or “something new.” 68% of donors and 69% of healthcare workers described the device as “easy” to use.

During the procedure and parallel use of the headset, initial anxiety, reported by 50.3% of participants who were mostly female, under 20 years of age, and first-time blood donors, was significantly reduced in 68.4%. For everyone, anxiety reduction increased by an average of 3.6 times. 54% of anxious donors had a strong desire and readiness to use the device again.

There were also mild “side effects” that occurred in 4.6% of participants: near-syncopal vasovagal reactions and hematomas were common.
