Module 1: Lesson 1
Compare paper and electronic CRF workflows, identify unique error risks for each, understand correction requirements by medium, and apply data integrity principles across both systems.
A conceptual hero image depicting the convergence of paper and electronic CRF workflows under a single set of data integrity principles. The left side shows a paper CRF page with a handwritten entry, a pen, and a multi-part carbon form fanned slightly to reveal duplicate copies beneath. The right side shows an EDC screen with structured data fields, an audit trail log, and a real-time edit check notification. Between the two sides, a central column of shared principles -- attributable, legible, contemporaneous, original, accurate -- bridges both systems, conveying that the medium differs but the obligations do not.
There is a question I have heard in nearly every GCP training session I have conducted since the late 1990s, when electronic data capture systems first began displacing paper case report forms in large-scale trials. Someone raises a hand -- usually a coordinator with several years of paper CRF experience -- and asks a version of: "Does EDC change the rules?"
The answer is no. And understanding why it is no -- deeply, not just as a memorized fact -- is what this lesson is about.
ICH E6(R3) does not prescribe a medium. It prescribes principles. Data must be attributable, legible, contemporaneous, original, accurate, complete, secure, and reliable regardless of whether those data are recorded in blue ink on a multi-part carbon form or typed into a validated electronic system with real-time edit checks and an automated audit trail. The guideline's language in Annex 1, Section 4 is deliberately technology-agnostic: it speaks of "data acquisition tools" and "computerized systems" without privileging one format over another.
But here is what changes, and it changes substantially: the how. How you enter data. How the system prevents certain errors and introduces others. How corrections are made, documented, and verified. How the sponsor accesses the data. How the audit trail is maintained. The principles are the what -- the fixed obligations. The medium determines the how -- the specific workflows that fulfill those obligations.
You will encounter both systems in your career. Some sponsors still use paper CRFs, particularly for small investigator-initiated trials and studies in resource-limited settings. Most large, sponsor-funded trials use EDC. And a surprising number of studies use hybrid workflows -- paper source documents transcribed into electronic CRFs, or EDC systems supplemented with paper worksheets for data that the system cannot capture. You need to understand both.
