From Protocol to Practice: Preventing Deviations Before They Happen
A closer look at how protocol clarity and SOP alignment directly impact compliance outcomes during FDA inspections.
Protocol deviations are the bane of clinical operations. While some are unavoidable—weather delays preventing a subject visit, for instance—the vast majority of deviations are self-inflicted wounds caused by ambiguous protocol language and conflicting Standard Operating Procedures (SOPs).
The Clarity Imperative
When a protocol dictates that an assessment must occur "prior to dosing," does that mean 5 minutes prior, or any time within the preceding 24 hours? Without explicitly defined time windows, sites are forced to interpret the protocol, leading to inconsistent execution and inevitable deviations.
Preventing deviations requires a rigorous, cross-functional review of the protocol before it is finalized. Clinical operations, data management, and quality assurance must evaluate the protocol not just for scientific validity, but for operational feasibility. A protocol that cannot be flawlessly executed in a real-world clinical setting is a failed protocol.
