Given that Wikipedia is the most read resource by medical practitioners, the interview has many relevant pointers on ensuring safe practices. I quote them from the paper and with some modifications they apply to any and all sources used in Wikimedia content.
- A retraction filter (or whatever mechanism the database in question allows) must be applied to the end output of any search strategy.
- Journals/databases must make retractions more visible (step 1 above depends on it).
- Collaborations (e.g. Cochrane, Campbell, The JBI) need to incorporate into their handbooks directives around retraction. For example, a scan for retractions after data sourcing; a scan for retractions before data extraction; a scan for retractions before review submission.
- The reporting guidelines for systematic reviews (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA) needs to include an item stating that authors have checked if any included studies have been retracted.
- Journal editors should require authors, when submitting manuscripts, to confirm that they have checked that none of the included studies have been retracted. Authors should also include a statement in the paper stating they have done this.
- Proofreaders may also have an important role to play. For example, authors of one review included in their reference list a citation that clearly indicated the reference was for a retracted paper. Proofreaders could be trained to spot and report these anomalies.
Registering retractions in Wikidata would be a start.
