GRIDD Project Phases & Outcomes

The GRIDD project, a multi-year, multi-phases project will  produce benefits that will endure for generations to come.

The implementation of each phase will result in a new GRIDD methodology called Global Research of Impact on Patients (GRIP),  a novel Patient-Reported Impact of Dermatological Diseases (PRIDD) measurement tool, as well as a data that will help transform the way the world sees and addresses dermatological diseases.

GRIDD Project Timeline: 2017 – 2024

Phase 1 - A Systematic review of published patient-reported outcomes (PRO) measures of the life impact of dermatology diseases and expanded the patient-centred item (impact) identification inventory. Design and implement the GRIP methodology.

Phase 1









Systematic Literature Review - Completed

  • Engaged with leading academic institutions and their experts to co-lead the GRIDD project.

  • Conducted a systematic literature review of 12,957 existing patient-centered outcome measures used in dermatology using databases including PubMed; Embase; PsychInfo; Cinhal. Findings from this systematic literature review revealed that existing measures used both in research and clinical settings don’t meet the scientific standards.

  • 59 generic, 23 dermatology-specific and 149 disease-specific patient-reported outcomes (PROs) used in dermatology research and practice were identified. None met COSMIN Standard A

  • Initiated a patient-centred item (impact) identification inventory

The results from GRIDD Phase 1 Systematic Literature Review (2017-2018) found that existing patient-impact measurement tools (questionnaires) used in both dermatology research and clinical settings don’t meet the commonly accepted scientific standards. This means there is currently no COSMIN A Standard for dermatology.GRIDD will address this gap with PRIDD: the A Standard patient-impact measurement tool that will provide the data for many applications including elevating dermatology in the global disease rankings;
allowing the integration of the patient’s voice in dermatology care and treatments and ultimately provide those with dermatology conditions worldwide a better quality of life.
