Choice architecture for young adult blood donor recruitment - a feasibility study.
2021
Blood shortages remain an ongoing challenge, ameliorable by increasing blood donations. Choice architecture is an emerging concept in psychology dealing with the targeted presentation of options to encourage a desired decision. A pilot study was designed to test the feasibility of implementing six choice architecture strategies on a Midwest high-school blood drive. These include framing, conformity, mere measurement, availability heuristic, loss aversion and status quo bias. A pre-post interrupted time-series evaluation was performed to evaluate for an immediate impact on blood donations. All six of the intended choice architecture strategies were successfully implemented. The pre-intervention 5-year average number of blood donations per blood drive was 15 (4.3% of age eligible donors) whereas post intervention, the number of blood donors rose to 25 (7.1% of age eligible donors; p-value = .0013). The application of choice architecture to blood donor recruitment strategies is feasible and has the potential to reduce the burden of blood shortages.
