Granular Data Selection and Altruistic Benefit Framing Increase EHR-Based Research Data Donation: A Mixed- Methods Study
This mixed-methods study demonstrates that offering patients granular control over specific data entries and framing the donation in terms of altruistic public benefit significantly increases both their willingness to donate electronic health record data for research and their trust in the data recipient.

Imagine your digital health record as a massive, high-tech backpack filled with every story your body has ever told: the scraped knee from childhood, the flu you fought last winter, the prescription for your anxiety, and even the embarrassing moment you caught a cold at a party. Now, imagine scientists want to peek inside these backpacks from millions of people to find patterns that could cure diseases or make hospitals run smoother. This is the world of Electronic Health Records (EHRs) and secondary data use. It's a bit like a library where your medical history is a book; usually, you only let the librarian read it to help you personally. But what if you could lend that book to a research team to help solve a mystery? The big question isn't just can they read it, but will you let them? People are often worried about privacy, or they might think, "Why should I share my secrets?" This study dives into how we can design the "permission slip" for this data sharing so that people feel safe, trusted, and actually want to say yes.
The researchers from Technische Universität Berlin set up a clever experiment to test two specific "superpowers" they could give to the permission slip: Granular Data Selection and Benefit Framing. Think of Granular Data Selection like giving you a pair of scissors. Instead of being forced to either hand over your entire backpack or keep it locked tight, you get to cut out specific pages you don't want to share. Benefit Framing is the sales pitch: are they telling you, "This helps everyone" (Altruistic), "This helps you specifically" (Self-benefit), or both?
In their first study, they invited 632 people to interact with a realistic mock-up of a German health app. They randomly assigned these participants to different scenarios: some could pick and choose their data, while others had to take it or leave it. They also showed different versions of the "why" message. The results were surprisingly clear. When people were given the scissors—the ability to select or deselect individual health entries—78% of all participants ended up donating their data, but those with the choice were significantly more likely to say yes. In fact, having the option to choose made people 3.13 times more likely to donate than those who couldn't. It turns out, giving people control is a massive trust-builder.
The study also tested the sales pitches. When the message focused on altruism—explaining how the data would help other patients and medical research—donation rates jumped significantly compared to saying nothing at all. However, the "self-benefit" pitch (telling people it might help them personally in the future) didn't work any better than silence. It seems people are more motivated by the idea of helping the greater good than by vague promises of future personal rewards. Interestingly, the researchers found that while people were generally willing to share, they were picky about what they shared. Among those who could choose, over 90% donated data for common things like insect bites or broken wrists. But when it came to sensitive topics like depression (74.6% donated) or gonorrhea (83.5% donated), people were much more likely to cut those pages out.
In a second phase, the researchers sat down with 30 people to chat about their choices. They found that the "scissors" (data selection) were loved because they allowed people to keep their dignity intact. Participants felt that being able to hide their most sensitive entries made them feel safer and more in control, which actually made them more willing to share the rest of their data. As for the messages, the interviews confirmed that people viewed data donation as a civic duty to help society, rather than a transaction for personal gain.
So, what's the takeaway? If you want people to share their health data for research, don't just ask for it all or tell them it will make them rich and healthy. Instead, give them a pair of scissors. Let them decide exactly which pages of their medical story they want to share. When people feel they have control over their sensitive secrets, they are much more likely to trust the system and contribute to the greater good. The study suggests that the best way to unlock the potential of health data isn't to force a "yes" or "no," but to offer a "yes, but only these parts."
