During a large medical emergency, which level of hospital surge management would most likely require mutual aid from external facilities?

• A. Tier Level 6
• B. Tier Level 2
• C. Tier Level 1
• D. Tier Level 3

Answer: (A)

Surge management levels increase as a hospital stretches beyond its normal capacity, moving from reorganizing within the facility to the point where demand overwhelms internal resources. At the top surge level, beds, staff, and supplies are so strained that the hospital cannot safely care for all patients using its own resources alone. This is when mutual aid from external facilities becomes necessary, with regional coordination, patient transfers, and use of additional outside resources to balance the load. Lower levels still rely primarily on internal adjustments—reallocating staff, repurposing space, delaying nonurgent care, and expanding contingencies—without needing outside hospitals to the same extent. So, the scenario that most clearly requires mutual aid from external facilities is the highest surge level.
