Why study startup takes so long, and where sites lose weeks

Short answerStudy startup averages 31.4 weeks from site identification to completion, per Tufts CSDD, and is no faster than it was 20 years ago. The contract and budget stages account for most of the cycle time, and budget misalignment between sponsor and site is one of the top causes of delayed starts, according to SCRS. Sites control their own turnaround, budget preparation, and readiness to enroll.

How long does startup take?

31.4 weeks from site identification to startup completion, about a month longer than a decade earlier (Tufts CSDD). Getz has noted that site activation is no faster today than it was 20 years ago, despite new technology (Clinical Leader).

Where does the time go?

  • Contracts and budgets. Tufts found the early stages, from contract and budget sent to execution and from execution to site initiation, account for the majority of cycle time (Applied Clinical Trials).
  • Budget misalignment. SCRS survey data ranks it among the top causes of delayed trial starts, often requiring multiple rounds of negotiation (Bourne Partners, citing SCRS).
  • IRB approval. Some sites never get through contracting and budgeting or never get IRB approval; about 40% of North American sites sponsors look to engage do not activate (Clinical Trial Vanguard).
  • Initiation to first patient. The most variable stage of all (Applied Clinical Trials).

Which delays does a site control?

  1. Turnaround time on CDAs, feasibility, contracts, and regulatory documents. Track your own days per step.
  2. A ready budget. Build your internal budget from the protocol before the sponsor offer arrives, with data backed justifications for each line (Bourne Partners).
  3. Standard documents on file: CVs, licenses, training certificates, SOPs.
  4. Patients waiting at activation. The stage after initiation is where prepared sites pull ahead.

How do sites use startup time well?

Startup is dead time for enrollment unless the site uses it. Reviewing records for candidates and briefing local physicians about the coming study mean referrals start arriving when the initiation visit ends rather than weeks later.

Why research coordinators leave, and how sites keep them

Site turnover runs 35% to 61% a year, and 85% of departing staff go to sponsors and CROs. Here is why coordinators leave, what turnover costs a site, and what keeps them.

Sponsor training burden: where coordinator hours really go

Sites average 17.5 hours per study per month on training, and 65% of mandatory training is considered redundant. Here is the data, the industry efforts to cut it, and what sites can do now.
