Statistical process control methods enhance clinical trial monitoring by analyzing patient data over time. These quality control tools improve data accuracy and trial management efficiency.

Area of Science:

  • Clinical trial methodology
  • Statistical quality control
  • Biostatistics

Background:

  • Clinical trials generate vast amounts of data requiring robust monitoring.
  • Traditional monitoring methods may not fully leverage accumulating data for real-time insights.
  • Industrial process control offers proven statistical tools for quality assurance.

Purpose of the Study:

  • To adapt and apply industrial process and quality control statistical methods to clinical trial data.
  • To address challenges in applying these methods to time-dependent patient and monitoring characteristics.
  • To demonstrate the utility of these methods in enhancing clinical trial oversight.

Main Methods:

  • Application of Shewhart charts, breakpoint regression, and recursive residuals.
