Medical associations and their publications how are you keeping clinical content current and actually read?

I spend a lot of time around the publishing side of medical associations and societies the journals, clinical guidelines, CME materials, and member-facing content these orgs put out. It's a corner of publishing that runs on different rules than most of what gets discussed here, and I'd love to hear how others are tackling a few recurring problems.

A handful of things that seem genuinely hard in this space:

• Content goes stale fast. Clinical guidance gets revised, but the published version often lives on as a static PDF. How are you handling versioning so members aren't reading outdated guidance?
• Engagement is low even when the content is good. Members pay dues, get access to a journal or guideline library, and then barely open it. Has anyone found formats or delivery methods that actually move usage?
• Accessibility is non-negotiable but expensive. Meeting WCAG / 508 on dense clinical material with tables, figures, and references is a real lift. Curious what workflows people use.
• Mobile. Practitioners want to pull something up between patients, not sit at a desktop. How are you making long-form clinical content usable on a phone?

If you work in or with a medical society on the publishing side: what's working for you, and what have you given up on? Genuinely looking for ideas and war stories here.
