Healthcare recruitment: verification burden is now the binding constraint

The supply of clinicians willing to take part in research has held up better than most predictions. What has changed is the evidentiary standard: clients increasingly need to demonstrate that a respondent was who they claimed to be, to a level that a self-reported specialty cannot satisfy.

Verification is now most of the cost

On specialist physician studies, verification and quality assurance routinely exceed the honorarium as a share of the cost per complete. Pricing models built when the honorarium dominated no longer describe the work.

Register coverage is uneven

Public registers make licence verification straightforward in some markets and impossible in others. Multi-country healthcare studies therefore run at different verification standards by market unless the design accounts for it, and the variation is rarely documented.

• Strong public registers: verification against an authoritative source
• Partial registers: verification of registration but not of current practice
• No accessible register: documentary evidence plus knowledge screening

What good looks like

A healthcare study that can be defended states its verification method per market, retains the evidence, and reports the rejection rate at each stage. A study that reports only a final sample size is asking the client to take the hardest part on trust.
