Station medical and evacuation capability — continuing enhancements

Station medical capability continues to be enhanced through 2024–2026 via COMNAP-coordinated protocols — including telemedicine links to home-country hospitals, standardised in-station surgical capability at larger stations, and refined winter-evacuation protocols. Overwintering medical evacuation remains possible only in narrow winter weather windows; most medical issues are managed on-station.

Who it affects: Overwintering staff at all national Antarctic stations.

Standardised station-health and psychological-screening protocols

COMNAP continues to coordinate standardised health-and-psychological-screening protocols across national Antarctic programmes — particularly for overwintering roles. Multi-week deployment workups, psychological interviews, medical clearance ("PQ" — Physically Qualified — in US Antarctic Program language), and dental fitness are the near-universal pre-deployment requirements.

Who it affects: Station personnel and prospective applicants across national programmes.
