ePRO Information

The EXACT was designed as an eDiary for use in clinical studies of COPD.

The EXACT eDiary is completed by study participants on a handheld electronic platform similar in size to a smartphone.

  • Although validation studies were conducted using the Palm® Tungsten E2, the instrument is transferable to other electronic handheld platforms.
  • Specifications for formatting and layout are available to assure ease of patient use and consistency across studies.

Although a paper-pen booklet is available, this method of administration is not recommended.

  • Paper-pen daily diaries are bulky, cannot be tracked for daily compliance, and require manual data entry with associated error risk, among other limitations.
  • All performance evaluations of the EXACT and E-RS are based on data from ePRO devices.
