The Short Answer
Recruiting physicians and other healthcare professionals is the hardest and most expensive recruitment problem in research, for three compounding reasons: incidence is tiny, honoraria are high, and the audience has almost no discretionary time.
Expect honoraria of roughly $3 to $8 per minute depending on topic, with 60-minute in-depth interviews running $200–$500+ before any provider margin. Combine that with a specialty-level incidence rate that can sit under 5%, and you are in the $50+ CPI territory described in our sample cost guide — often well above it.
The winning moves are: verify credentials properly, respect clinical schedules, keep instruments short, and use asynchronous formats so a cardiologist can participate at 21:00 between charting rather than on your calendar at 14:00.
Why HCP Recruitment Is So Difficult
Time is the binding constraint, not money. Physicians receive numerous research invitations, which makes engagement more challenging, and their working day is scheduled in advance in ways most professions are not. A $400 honorarium does not create a free hour at 14:00 on a Tuesday.
Incidence collapses fast at specialty level. "Physicians" is a feasible audience. "Rheumatologists who have prescribed a specific biologic to 10+ patients in the last six months" may be a few thousand people nationally. Every added criterion multiplies both cost and field time.
Verification is non-negotiable. High honoraria attract misrepresentation. Anyone can claim to be a physician in a screener, and the incentive to do so scales with the payment.
The category is heavily served — and heavily surveyed. Dedicated HCP panels exist precisely because general panels cannot deliver, and one HCP platform reported paying out $25 million in honoraria in a single year. That scale means the physicians reachable through panels are, by definition, the ones already answering a lot of research — the concentration issue covered in professional respondents and panel conditioning.
Where to Recruit HCPs
Specialist HCP panels. The default for pharma, medtech, and diagnostics work. They pre-verify credentials and hold specialty, practice setting, and prescribing profile. Fastest route to feasibility; highest exposure to frequent-responder concentration.
Professional associations and societies. Slower, often requiring approval, but reaches practitioners who are not panel members — valuable when you suspect panel bias.
Your own users. If you are a health-tech company, your clinician users are already identified, credential-verified through onboarding, and have a stake in your product. This is the highest-quality and cheapest frame available, and it is routinely overlooked.
KOL and referral routes. For very low incidence, snowball sampling through a small seed group is often the only feasible approach. Slow, non-representative, but sometimes the only way to reach 12 interventional neuroradiologists.
Health systems and clinics. Institutional recruitment usually triggers IRB review — plan for it early, and read our guide to IRB approval for user research.
Verification: What "Verified Physician" Should Mean
Ask any provider to specify:
- Licence-level verification against a primary source (NPI in the US, GMC in the UK, equivalent registries elsewhere) — not a self-reported screener
- Specialty confirmation independent of the respondent's own claim
- Re-verification cadence — credentials go stale as clinicians move, retire, or change specialty
- Duplicate prevention across blended supply, so the same physician is not reached twice through two suppliers
If the answer is "our panelists confirm their credentials at registration," that is self-report with extra steps. Use the ESOMAR 37 framework to press on validation properly.
Design Rules That Raise HCP Participation
- Keep it short and say so honestly. Understating length is the fastest way to burn an audience you cannot replace. Fifteen minutes is a realistic ceiling for most survey work.
- Go asynchronous. Scheduling is the biggest single point of failure. Anything requiring a calendar slot loses candidates who would otherwise have participated.
- Lead with clinical relevance. HCPs respond to research that engages real clinical judgment. Marketing-flavoured questions read as pharma promotion and depress both response and quality.
- Get the terminology right. Wrong drug class, wrong dosing convention, or wrong care-pathway language signals the study was not built by anyone clinically literate, and respondents disengage.
- Pay properly and promptly. Benchmark honoraria per minute, not per survey, and confirm the tax treatment — our guide to incentives and 1099 rules covers the mechanics.
- Plan for compliance up front. Patient data, adverse-event reporting obligations, and consent handling all shape the design. See HIPAA-compliant AI user research and interview recording consent laws.
Where Koji Changes the Economics
The dominant HCP cost is not the honorarium — it is the coordination around a person who has no free hour. Koji attacks exactly that:
- AI-moderated voice and text interviews run asynchronously, around the clock. A physician participates at 21:00 after clinic, in their own time. No calendar negotiation, no rescheduling, no no-shows consuming your field window.
- Every interview runs in parallel. 30 clinician interviews complete in the time one scheduled call takes — decisive when your audience is small and your field window is short.
- Invite known clinicians directly via CSV or CRM sync, with personalized interview links. For health-tech teams, incidence is 100% and credentials are already verified through your own onboarding.
- Customizable AI consultants carry correct clinical framing and terminology into every session, and probe follow-ups consistently — no interviewer variance across 30 conversations, no moderator bias.
- Six structured question types — open_ended, scale, single_choice, multiple_choice, ranking, yes_no — capture prescribing frequency or satisfaction ratings alongside the clinical reasoning behind them, in one study rather than a survey plus a follow-up IDI.
- Automatic thematic analysis and one-click reports turn a small, expensive sample into a decision immediately, instead of adding weeks of synthesis to an already long timeline.
- Published pricing — €29/month Insights, €79/month Interviews, credits included. Against $200–$500 per traditional IDI, the platform cost is a rounding error.

Frequently Asked Questions
How much does it cost to recruit physicians for market research? Honoraria typically run $3-$8 per minute, with 60-minute in-depth interviews at $200-$500+ before provider margin. Combined with specialty-level incidence often under 5%, effective cost per complete frequently exceeds $50 and can go much higher for narrow specialties.
How much should I pay a physician for a research interview? Benchmark per minute rather than per session. Quick 5-minute polls run $5-$15, while hour-long in-depth interviews reach $200-$500+. Specialists and rare profiles command more, and prompt payment materially affects willingness to participate again.
How do I verify that a research participant is really a doctor? Require primary-source licence verification (NPI, GMC, or the local registry) rather than self-report, independent specialty confirmation, a re-verification cadence, and duplicate prevention across suppliers.
Why is it so hard to recruit healthcare professionals? Time, not money, is the constraint. Clinical schedules are fixed in advance, HCPs receive a high volume of research invitations, and specialty-level targeting produces very low incidence rates.
What is the best way to interview busy clinicians? Asynchronous formats. Removing the calendar removes the biggest failure point — AI-moderated interviews let clinicians participate whenever they are free, including outside business hours, and run in parallel rather than sequentially.
Do I need IRB approval to research physicians? For commercial market research, usually not. Research conducted through health systems, involving patient data, or intended for publication typically does require IRB review — confirm before fielding rather than after.
