Speed to Contact: The Metric That Makes or Breaks Recruitment

When a potential participant submits an interest form, a countdown starts. Sales research has shown for years that contact rates collapse as minutes turn into hours; clinical trial recruitment behaves the same way. A person motivated enough to fill out a form at 9pm is rarely as motivated by Friday.

Why sites are slow

Almost no coordinator wants to be slow. Slowness is structural:

• Leads arrive in a shared inbox that gets checked between visits.
• Nobody is explicitly assigned to new leads on any given day.
• The lead's information lives in one system and the call log in another.

Building a fast-response operation

Route leads automatically. Every new lead should land in a queue with an owner the moment it arrives — not after someone exports a spreadsheet.

Set an SLA and measure it. Pick a target — say, first contact attempt within 2 business hours — and report on it weekly. What gets measured gets managed.

Use multiple channels immediately. An automated text or email confirmation ("We received your interest in the migraine study — a coordinator will call you today") buys goodwill and keeps the lead warm even if the call comes later.

Protect calling time. Sites that block 30 minutes each morning and afternoon purely for lead outreach consistently outperform those that squeeze calls between visits.

What good looks like

High-performing sites reach 70–80% of new leads because they attempt contact fast and more than once. Sites that respond within a day of "when we get to it" often connect with fewer than half. Same leads, same budget — the difference is entirely operational. Speed is free; you just have to design for it.
