Encouraging Blood Donation in Patients With a Blood Type in Short Supply
Encouraging Blood Donation in Patients With a Blood Type in Short Supply
As of November 2021, partly due to the COVID-19 pandemic, there has been a months-long national shortage of several types of blood in the U.S. (O-Pos, O-Neg, A-Neg, B-Neg, and AB-Neg), which has extended to a local blood shortage within the Geisinger community. The broad aim of this collaborative healthcare operations quality improvement project is to determine whether a message indicating that a patient's own blood type is in short supply increases the likelihood that they will donate, compared to a message that mentions a blood shortage without referencing the patient's blood type, or no message at all. Scientists in Geisinger's Behavioral Insights Team (BIT), part of Geisinger's Steele Institute for Health Innovation, will collaborate with Miller Keystone, where Geisinger refers patients who wish to donate blood and from whom Geisinger receives blood for clinical purposes. Patients with one of the needed blood types will be randomized to receive 1) a message about a blood shortage that does not specify the blood types in short supply or their own blood type (no-blood-type message), 2) the same message modified slightly to specify the recipient's blood type, and to mention that their blood type is in short supply (blood-type message), or 3) no message (shortage control group). A second no-contact control group of patients without any of the needed blood types will also be observed (no-shortage control group). Both the blood-type and no-blood-type messages are informed by behavioral science, emphasizing supply needs in local hospitals and providing community-relevant examples of why someone might need blood (e.g., farming or industrial accidents). The BIT will compare how many patients in each group choose to donate blood. They hypothesize that: 1) patients who receive either message will be more likely to donate than patients who receive no message; and 2) patients who receive the blood-type message will be more likely to donate than those who receive the no-blood-type message. With respect to the latter hypothesis, informing the recipient that they have one of the needed blood types may increase their perception that they are in a semi-unique position to help someone in need as compared to a more general message that may suffer from a diffusion of responsibility effect.
