Indeed, I think you have "focussed" on a key issue! That provision of practical "know-how" - reliable, relevant, actionable health care information - available when required offline (once downloaded) and in easily assimilable form e.g. "how-to" video clips, accounts for the good performance in assessments for HIFA of mHealth apps like the International Red Cross/ Red Crescent's First Aid app, the Mother and Child Health Education Trust's HealthPhone, and Hesperian's Safe Pregnancy and Birth app. ( See http://www.hifa.org/sites/default/files/publications_pdf/FINAL%202017%20... )
As you say, if valuable sources like Wikipedia could somehow be filtered and drawn upon to provide that sort of information, their use by citizens (and front line health care workers) would surely be increased.
