How do you recruit patients for market research without burning them out?

The big thing with chronic illness panels is keeping surveys under 10 minutes and spacing them out — we typically wait 6-8 weeks between touchpoints minimum. Also, small incentives tied to *each* survey (even $10-15 gift cards) beat a big payout at the end because people don't trust they'll see it. Patient advocacy orgs are also gold for warm recruitment since those patients are already motivated to contribute.
