Congresses occupy an unusual place in medical culture. They're expensive, carbon-heavy, and take doctors away from their patients for days at a time. They're also genuinely valuable, and the medical profession knows it, which is why attendance hasn't declined even as digital alternatives have multiplied.
Before arguing that something needs to change, it's worth being honest about what congresses actually do well. And before dismissing the criticism, it's worth being equally honest about where they structurally fall short.
Congresses do three things that other formats haven't matched
They create shared moments. There's something that happens when a large field gathers in one place that asynchronous formats haven't replicated. Major trial results land differently when presented in a full auditorium. Debates sharpen when the people disagreeing are in the same room. The informal exchanges between people who otherwise only know each other's papers produce something with real professional value.
They signal what the field thinks matters. A conference programme is a curated argument about where a discipline is directing its attention. The curation reflects the biases of whoever is doing the selecting, but it still provides a useful read on collective priorities.
They create a predictable moment for CME. For many doctors, the annual congress is when formal CME obligations get met. That's not ideal as a design, but it works as a mechanism: it creates a socially reinforced moment for structured learning that busy clinical schedules might otherwise crowd out.
But they were never designed for staying current
The problem isn't that congresses are bad. It's that they're being asked to do something they weren't built for.
Relevance is a structural casualty. A congress programme has to serve an entire specialty. The sessions directly relevant to any individual attendee's subspecialty, patient population, or clinical questions will always be a fraction of the total. You can pre-select sessions, but you can't change the fundamental tension between breadth and relevance that the format creates.
Batch learning leaves gaps the rest of the year. Attending once or twice a year means long gaps between structured exposure to new evidence. In a field where relevant research is published continuously, that cadence creates a problem that congresses aren't designed to solve.
The costs are real, and not only financial. Two days at a congress means two days away from patients and everything else that fills a clinical week. The CO2 cost of international medical travel is recognised in the medical literature and by professional associations as a meaningful problem. These aren't reasons to stop attending, but they're real costs that should be part of how the profession evaluates its CME infrastructure.
The question isn't whether to attend. It's what fills the rest of the year.
Congresses aren't going away, and they shouldn't. The things they do well, community, shared moments, collective curation, are genuinely hard to replicate. But treating them as a complete answer to how doctors stay current is a category error. They were never designed for that, and the evidence that doctors feel chronically behind despite attending them regularly suggests the gap is real.
The annual congress handles one moment. The other fifty weeks still need something.
