Saving studies with reader and assessor training

Sunday, January 1, 2017

Although many CROs offer out­standing research capabilities, not every assessor or overreader receives sufficient instruction to reduce variability and error. To avoid multimillion-dollar misfor­tunes, sponsors should prioritize assessor and overreader education to improve data quality.

  1. Site evaluators or assessors must receive protocol training to reduce variability amongst data collection personnel. This should highlight: study endpoints, enrollment criteria and demo­graphic requirements; patient preparation to be completed before acquiring data points; equipment operation procedures for consistent data collection and entry; the laboratory’s data acquisition standards, including patient-specific lead placement at each time point and expla­nations of protocol-required imaging sequences; and query resolution processes.
  2. Overreading physicians must receive training prior to subject assessment to minimize inter- and intra-reader variability. Training should include: re­views of protocol design, pri­mary and secondary endpoints, time points and assessment criteria; an intracalibration session reviewing reading techniques, discussing scor­ing definitions and practicing reading case examples using central laboratory systems; an intercalibration session com­paring findings to one another and to diagnostic standards; individual review sessions to certify performance before reading study cases; periodic reviews to test for variability and recalibrate; and adjudica­tion procedures—some studies use multiple overreaders with an adjudicator.

Well-trained readers and as­sessors are essential to reducing clinical trials’ data variability. With the ever-increasing costs, complexity and number of clinical trials, sponsors must rigorously train CRO personnel to maximize drug approval chances.
