Manual fidelity, protocol adherence, and deviation management

The manuals converge on a strong expectation of manualised, protocol-defined delivery. Across the extracts, fidelity is tied to following the approved therapy manual, keeping to the specified sequence and timing of preparatory, dosing, integration, follow-up, or assessment procedures, and maintaining accurate documentation in source records, eCRFs, or research charts. Many also link fidelity to participant safety, data integrity, and audit or inspection readiness. They also converge on active monitoring of adherence. Several sources describe checklists, supervision, audio or video recording, blinded or central review, and sponsor or monitor feedback as ways to detect drift and support corrective action. Deviation management is a repeated theme, with manuals referring to documenting departures, escalating significant or unresolved deviations, and recording corrective actions. Sources differ in how much flexibility they allow. Some emphasise strict protocol compliance and avoidance of unapproved deviations, waivers, or off-protocol interventions, while others explicitly allow clinical judgment or flexibility within protocol boundaries, especially in response to participant safety or unfolding experience. The manuals also differ in emphasis, some focus heavily on psychotherapy fidelity and therapist behaviour, while others foreground operational requirements such as visit windows, eligibility, washout periods, controlled substance handling, or regulatory reporting.
