What is PROQOLID™?

PROQOLID™ is a comprehensive online database designed to assist academic researchers, physicians, students, pharmaceutical companies, health authorities, and international organizations in the search and evaluation of Clinical Outcome Assessments (COAs).

The success of Patient-Centered Outcomes (PCO) Research depends a great deal on the choice of appropriate COAs. They should be selected by the domains they measure as well as the populations and the therapeutic areas they cover. Practical issues such as the availability of translations, copyrights, and access to COAs are also important considerations.

Mapi Research Trust created the PROQOLID™ database in 2002 as a tool to help you find the COA that is right for your needs and to provide a better knowledge and understanding of the relevant use of COAs.

The database has grown exponentially over the years, based on recommended sources such as the FDA (U.S. Food and Drug Administration), the EMA (European Medicines Agency), and the Research and Development scientific community.

What can be found in PROQOLID™?

Today, more than 2300 COAs are comprehensively described in the PROQOLID™ database, providing users with two levels of information access:

  • A free access level corresponding to basic information on the COA and available to all users at no charge
  • A member access level available to users who subscribe to PROQOLID™. A username and password are required to access this advanced level of information.

PROQOLID™ mainly focuses on the original COAs developed: it provides descriptive information on COAs as well as descriptions of COAs related to the original (if relevant). The adequacy of the study methodology and the psychometric properties are not evaluated.

The access provided by PROQOLID™ does not constitute a license to use the COAs

The COAs presented in PROQOLID™ may have specific conditions of use. PROQOLID™ does not provide copies of the COAs. In some cases, PROQOLID™ may provide review copies of COAs for information purposes only. Should users of PROQOLID™ wish to use a copyrighted COA described in PROQOLID™, users should contact either the copyright holder of the COA or Mapi Research Trust in order to ensure compliance with the conditions of use of the COA.
