Why do we do some of the things we do in clinical study reports? Part 1

Over the past three months I have been doing a series of workshops focused on the authorship of clinical research reports for a couple clients. This work has me posing questions about two very specific notions
  1. Why do people still demand that a clinical research report intended for incorporation into regulatory submission packages must be written as “stand-alone” documentation?
  2. Why do we still organize clinical research reports by the long-standing convention of Introduction, Objectives, Methods, Results, Discussion, and Conclusion?

In this post let’s consider the notion of the “stand-alone” clinical study report.

First question I have is why must these documents be stand alone? The term “stand alone” generally refers to a document or device that is self-contained and does not require any other document or device to fully function. I argue that a clinical study report submitted to a drug regulatory agency is part of a larger corpus and as such the report should never be construed as a stand-alone document.

It is a given that most submissions made to drug regulatory agencies contain multiple research studies. So you will never have a “stand-alone” research study. So an individual study is part of a corpus of clinical research that best operates collectively. Also regulatory submissions have multiple sections as mandated by guidance that are topoi (places of argument) for different and often integrated attributes of clinical research drawn from this corpus. So clearly the clinical study report is not a stand-alone document in the instance of interpretation and argumentation.

Another point, a clinical study report incorporated into a regulatory submission will have numerous appendices including the final version research protocol and the statistical analysis plan. So I struggle to understand the premise that says you must incorporate extensive elements of the protocol and stats plan into the body of the clinical study report in order to assure the report is a stand-alone document. I truly fail to see the merit of this premise.

My last point is why do so many feel it is necessary to write the Introduction Sections to clinical study reports in the classic inductive form of rhetoric that moves from describing the disease condition, to the therapeutic void, to the chemical or biological construct of the drug under study and how this drug’s pharmacological action addresses a therapeutic void. The standard response is, “well we want to make this a stand-alone document.” Why? All the rhetorical moves you are trying to make in the Introduction will happen for sure elsewhere in the drug submission package in the appropriate topos. So why waste your time here, at the low level of the clinical study report? In my way of thinking the study report Introduction is intended to convey only two points:
  1. Why are you doing the study (the answers to what questions do you want at the end of the study that you do not have now?)
  2. What previous work has informed the design of this study?
