Patient flow,
finally made visible.
For Ramsay Santé, Pole Star deployed continuous patient tracking across ambulatory services - powered by NAO® Track NG - to turn invisible patient flow into something teams can actually see and optimize.
High throughput, low visibility
Ramsay Santé is one of the world's leading private healthcare providers. In its ambulatory services, large numbers of patients pass through every day - arriving, being seen, and leaving without an overnight stay.
Ambulatory services are outpatient care delivered without an overnight admission - consultations, diagnostics and day procedures where a patient arrives, moves through several steps, and goes home the same day.
That throughput is exactly what makes flow hard to see. A patient moves from reception to waiting to consultation to exam to discharge - and when that movement isn't tracked, bottlenecks and waiting times stay invisible until they show up as frustration.
Track the people, and the flow reveals itself
Pole Star deployed continuous tracking of people within ambulatory services - each patient carrying a lightweight BLE wristband tag, located as they move through every step of their visit.
Continuous people tracking
Patients are located continuously across ambulatory services - the whole journey, not just check-in and check-out.
Lightweight patient tags
A simple wristband tag does the work - nothing for the patient to operate, nothing to install.
Flow you can act on
Movement data makes waiting times and bottlenecks measurable - the first step to smoothing them out.
Tracking that lasts - because maintenance is the real cost
In a live clinical setting, a tracking system is only useful if it stays running with minimal upkeep. So the deployment was tuned - through specific infrastructure and tag configuration - to stretch battery life as far as it will go.
How the battery is saved
The key is motion-triggered tracking: a tag only works hard when the patient is actually moving. When someone is sitting still - in a waiting area or a consultation - the tag goes quiet, and the battery isn't spent reporting a position that hasn't changed.
Paired with a tuned beacon layout, that keeps both the fixed infrastructure and the patient tags alive far longer than an always-on approach would allow.
A BLE tracking chain, tuned for the ward
Patient tags broadcast over Bluetooth Low Energy; fixed devices pick up the signal; and NAO® Track NG turns it into a live position - the same architecture, replicated across each deployment.
Patient tags
Lightweight BLE wristbands, motion-triggered to save battery.
NAO® BlueSpot
BLE beacon infrastructure - up to 10 years battery life.
NAO® BlueListener
Captures tag signals and feeds the positioning engine.
NAO® Track NG
The engine that computes continuous, real-time position.
Not a pilot - a pattern, deployed three times
Delivered across three deployments - the same architecture and tag configuration proven and replicated, not reinvented site by site.
Flow becomes measurable
Continuous tracking makes patient movement and waiting visible - the basis for optimizing it.
Low-maintenance by design
Battery-optimized tags and beacons mean less upkeep in a busy clinical setting.
Ready to scale
A proven, repeatable pattern that extends to further sites with confidence.

See the flow you've
never been able to measure.
If patients queue in your outpatient services and you can't see where the time goes, the same continuous, battery-optimized patient tracking - powered by NAO® Track NG - can be deployed in your facilities and replicated across sites.
