What successful adaptation reveals about capability and dependence in healthcare: A Brittle Threshold perspective

Successful adaptation in hospital, military, rural emergency, and community vaccination teams reorganizes collective work across four domains, revealing Brittle Threshold signals beyond task completion.

• Why it matters: Teams can keep performance after adapting, but success alone hides how the supporting conditions for later adaptation may be narrowing.
• What they did: A secondary qualitative analysis of 34 anonymized interviews from four studies during COVID-19, military surgical resuscitation, rural emergency care, and community-led mass vaccination used Brittle Threshold as a sensitizing concept.
• The result: Adaptations were sustained under varied conditions, sometimes via shared learning and expanded skills or alternative support, and sometimes by continued dependence on specific individuals, restricted access, or sustained personal effort.
