The goals of this project are to increase the efficiency and effectiveness of clinical research studies and treatment, increase data quality, facilitate data sharing and aggregation of information across studies, and help educate new clinical investigators. Background In December 2016, members from the world-wide ME/CFS community were invited to join a CDE development working group (WG) to prepare standard template case report forms (CRFs) and instrument recommendations for clinical research studies. The almost 60 member WG is comprised of patient advocates, clinicians and researchers whose expertise includes a variety of ME/CFS research domains. Design/Methods The CDE WG divided into thirteen subgroups: (1) Baseline/Covariate Information; (2) Fatigue; (3) Post-Exertional Malaise; (4) Sleep; (5) Pain; (6) Neurologic; (7) Cognitive; (8) Central Nervous System Imaging; (9) Autonomic; (10) Neuroendocrine; (11) Immune; (12) Quality of Life/Functional Status/CPET/Activity; and (13) Biomarkers. Regular subgroup meetings were held to discuss their purview, review forms and instruments within their domain currently used in ME/CFS research and applicable CDEs from other NINDS CDE disease recommendations. Results Working group end products included a summary of recommendations, templates (CRFs), CDE detail reports, instrument recommendations, and guideline documents. Public Review is scheduled for December 2017 - January 2018 to elicit feedback from the community. The version 1.0 recommendations are expected to be posted to the NINDS CDE website in late February 2018. Conclusions NINDS/CDC encourage the use of CDEs by the clinical research community to expedite study start-up, standardize data collection, and allow for future data sharing. The development of CDEs is an iterative process. Updates will be made to these ME/CFS CDEs as research progresses and feedback is received from the community.
