Participant recruitment is the single most common reason usability studies get delayed or compromised. Finding qualified clinicians who match your screener, are available on your study dates, and actually show up is harder than most teams anticipate. This guide covers the full process: writing screeners, sourcing participants, managing no-shows, and handling incentives.
IEC 62366-1 requires you to define intended user groups as part of your use specification. These user groups drive your recruitment. Each group needs its own screener with specific inclusion and exclusion criteria.
Common user groups in medical device studies include physicians (by specialty — ED, ICU, surgery, cardiology, radiology, primary care), nurses (RN, NP, CRNA — by specialty and setting), surgical technologists, respiratory therapists, biomedical engineers, pharmacists, patients (by diagnosis, treatment history, health literacy), and lay caregivers.
Your screener is the filter that determines who qualifies. It should capture professional credentials and licensure, years of experience, clinical setting (hospital, clinic, home health, ambulatory), experience with similar devices or procedures, frequency of relevant tasks, and any exclusion criteria (employment at a competitor, prior participation in studies for this device, conflicts of interest).
Keep screeners focused. Overly restrictive criteria narrow your feasible pool and extend recruitment timelines. If a criterion isn't directly tied to your use specification or risk analysis, question whether it's necessary.
Healthcare professionals are hard to reach through traditional market research panels. The most reliable channels are direct relationships with health systems and academic medical centers, where you can work through nurse managers and department chiefs to identify candidates. Professional society networks and patient advocacy organizations are also productive, especially for specialty populations.
Location matters. Markets with large academic medical centers and diverse health systems provide deeper recruitment pools. Minneapolis, for example, offers access to the University of Minnesota Medical Center, M Health Fairview, Allina Health, and Hennepin Healthcare, which collectively cover virtually every clinical specialty.
For certain studies — particularly those involving consumer or patient populations — FDA may expect that recruitment not reveal the study sponsor or device identity. This is called self-selection blinding, and it means your recruitment advertising and screener cannot mention the company name or product.
Participants must self-select based on their own characteristics, not based on interest in a specific product. This adds complexity to recruitment and requires careful screener and advertising design.
Clinician no-show rates are a reality of usability research. Physicians get pulled into emergencies. Nurses get called for extra shifts. The single most effective mitigation is over-recruiting by 20-30%: if you need 15 completions, recruit 18-20.
Beyond that, confirmation cadence matters. Reminders at 48 hours, 24 hours, and morning-of significantly reduce drop-off. Schedule backup participants for each session slot when possible, and keep incentives at fair market value for the specialty. A $150 honorarium that made sense for a lay user will not hold an interventional cardiologist's calendar.
Participant incentives must reflect fair market value for the participant's time and expertise. Rates vary significantly by user group: lay users may accept $75-150 for a 90-minute session, while specialist physicians may require $300-500+ per hour.
Incentives must be compliant with applicable regulations (Open Payments / Sunshine Act for physicians). Handle incentive distribution professionally — same-day payment, clear documentation, and W-9 collection as required.
