Good Clinical Practice is a standard most people in research know by name. Fewer talk about what it looks like when it is actually working — not just on inspection day, but on the day-to-day level of source documentation, participant interactions, and protocol deviation reporting. Justin Coffeen, a clinical research professional based in Lakewood Ranch, Florida, holds IHI Good Clinical Practice certification and has worked across orthopedics, oncology, and hepatology research.
What GCP Is Designed to Do
GCP is an international ethical and scientific quality standard for designing, conducting, recording, and reporting clinical trials involving human participants. The standard exists to ensure that trial data is credible and that the rights, integrity, and confidentiality of trial participants are protected. Those two goals — data quality and participant protection — are not separate priorities in GCP. They are the same priority expressed from different directions.
In practice, GCP compliance means that every data point entered into a case report form can be traced back to a source document. It means that protocol deviations are identified, documented, and reported rather than corrected quietly. It means that consent was obtained before any study procedure occurred, and that consent was genuinely informed rather than procedurally satisfied.
Where Compliance Tends to Break Down
Most GCP failures are not the result of intentional misconduct. They are the result of pressure — site pressure to enroll, time pressure to complete assessments, institutional pressure to maintain sponsor relationships. Under that pressure, documentation shortcuts develop. A note written from memory three days after a visit. A consent form signed after the blood draw. A deviation reported weeks late because no one was sure whether it met the threshold.
The problem with each of these is not just regulatory. It is epistemic. The data becomes less trustworthy. A record written three days after the visit reflects what the coordinator remembers, not necessarily what the participant reported. That distinction matters in a phase III trial where participant-reported outcomes are primary endpoints.
The Practical Habits That Keep a Site Compliant
Compliant sites tend to share certain habits. Source documents are written contemporaneously — at the visit, not after it. Protocol deviations are reported promptly, because the culture at the site treats early reporting as professional rather than embarrassing. Consent discussions are treated as real conversations, not signatures to collect.
The clinical background that Justin Coffeen brings to research work is relevant here. As a practicing chiropractic physician and clinical instructor, he spent years in settings where documentation was tied directly to patient care decisions. A chart entry in a clinical practice matters because a future provider may read it and make a treatment decision based on it. That same orientation carries into research: the record matters because a regulatory reviewer, a statistician, or a future patient may rely on it.
GCP as a Professional Standard, Not Just a Requirement
It is possible to view GCP compliance as an external requirement — something imposed by sponsors and regulators that a site manages around. It is also possible to view it as a professional standard that reflects the actual obligations of working with human participants in a research context. The latter view tends to produce more consistently compliant sites, because the motivation for documentation accuracy is internal rather than inspectional.
For Justin Coffeen, that internal motivation is connected to the clinical training he brings to research work. Participants in clinical trials are not just data sources. They are people who have enrolled in a study, often because they or someone they know is dealing with a condition the study is trying to address. That context does not change the documentation requirements. It gives those requirements their purpose.
