Ambulance Diversion Avoidance vs. Equitable Regional Load Balancing

Business Context

Individual hospitals seek to avoid ambulance diversion, the practice of redirecting incoming ambulances to other facilities when at capacity, because diversion delays care for patients already en route and can strain relationships with emergency medical services. At the same time, a regional health system, or a set of hospitals serving overlapping populations, benefits from load balancing, distributing patient volume across facilities so that no single hospital becomes critically overwhelmed while others operate below capacity. A hospital that never diverts, out of local operational pride or contractual pressure, may absorb dangerous overcrowding that a regional load-balancing approach would have prevented.

Healthcare TRIZ Resolution

Rather than treating diversion avoidance and regional load balancing as opposing goals, the resolution establishes a shared, real-time regional capacity visibility system that allows emergency medical services and hospital operations centers to see current capacity across all participating facilities, and applies load balancing proactively, before any single facility reaches crisis capacity, rather than reactively through last-resort diversion. This shifts the mechanism from an individual hospital’s binary diversion decision to a continuous, regional, data-driven redistribution of incoming patients.

Applicable TRIZ Principles

Principle 5 – Merging Merge individual hospital capacity data into a single, shared regional visibility system rather than leaving each facility to manage its own capacity in isolation.

Principle 15 – Dynamics Redistribute incoming patient volume continuously and proactively based on real-time capacity data, rather than through an infrequent, binary diversion decision.

Principle 23 – Feedback Provide continuous feedback on regional capacity status to emergency medical services dispatch, so routing decisions reflect current conditions rather than default patterns.

Expected Outcome

Reduced crisis-level overcrowding

Fewer diversion events

More equitable regional load

Better regional visibility

Decision Indicators

Early indicators that this contradiction is limiting organizational performance include:

Wide disparities in occupancy between nearby facilities serving overlapping populations, without a mechanism to redistribute volume

Diversion decisions made in isolation by individual hospitals without visibility into regional capacity

Emergency medical services routing patients based on default patterns rather than current capacity data

No shared regional capacity dashboard or equivalent visibility mechanism across participating facilities

Repeated crisis-level overcrowding at one facility coinciding with underutilized capacity at a nearby facility

Monitoring these indicators helps regional health system and emergency medical services leadership recognize when a lack of shared visibility, rather than absolute regional capacity, is the true constraint.
