Where do the default benchmarks come from?
- Screen failure 36.3% and dropout 19.1%: Tufts CSDD Phase II and III averages (Tufts CSDD).
- Why budget matters: 53% of sites regularly pay for recruitment from their own funds (SCRS), so the plan should name what the sponsor funds.
- Approvals: FDA treats ads and flyers for prospective subjects as materials IRBs review (FDA).
- Staffing: one 25 practice trial measured 3.7 staff hours per randomized patient (PMC).
How do you keep the plan useful?
Review it weekly against actual numbers by source. Recruitment is the improvement area sites rank first, at 65% in SCRS's survey (SCRS); a plan that is updated weekly is how it gets managed rather than hoped for. See how to write a recruitment plan.
