What term refers to detailed, written instructions to achieve uniformity of the performance of a specific function?

• A. Adverse Event Log
• B. Case Report Form
• C. Standard Operating Procedures (SOPs)
• D. Study Protocol

Answer: (C)

Standard operating procedures (SOPs) are detailed, written instructions that guide how a specific function should be performed to achieve consistent, uniform results. In clinical research, SOPs lay out the exact steps, responsibilities, and required documentation so that every person carries out a task the same way, regardless of who does it. This standardization supports reliability, quality, and regulatory compliance. For example, a SOP on obtaining informed consent would specify the exact language to present, the process for documenting consent, who can witness signatures, and how to handle situations where a subject cannot sign.

An adverse event log is simply a place to record events, a Case Report Form is the document used to collect trial data, and a study protocol outlines the overall plan and design of the trial, not the step-by-step execution of routine tasks.
