All data including studies and users are stored in IPSM. The screening and data extraction will be done through croudsourcing and thus we decided on using the survey functionality of REDCap where each record is assigned to a reviewer indicated in the database.
Since we follow a three stage review process we had to multiply each instrument for screening and extraction three times. As the complexity increased the dictionnary functionality of REDCap was not sufficiently efficient and we moved on using the programming language Dhall to describe our schema which made changes through the protoptyping phase much faster. The dhall-REDCap api we build can be found here
We are using published studies from ISPM’s Living Evidence on COVID-19 systematic review.
