56.8%
of everyone who left a hospital had under two years of service. The average RN tenure is 6.8 years — but the unit is re-staffed constantly at the junior end.
Where Noria Is Going
The Senior Nurse Who Never Leaves the Unit
Nursing has always run on apprenticeship — juniors got good by working beside veterans who had seen the septic patient go bad before the vitals said so. That transfer is breaking down. Noria is building the layer that carries it instead.
Experience Compression
The problem isn't that nurses are inexperienced. It's that experience keeps leaving before it transfers — and it leaves from the junior end, fastest.
29.0%
of all RN separations are first-year nurses. Nearly a quarter of newly hired RNs (22.7%) leave inside twelve months.
$60,090
to replace one bedside RN. The average hospital loses $5.19M a year to RN turnover, and every point of turnover is worth $294,976.
All figures:NSI Nursing Solutions, 2026 National Health Care Retention & RN Staffing Report(data covering CY2025).
“These departments will turn over their entire RN staff in less than four and a half years.”
That is NSI describing telemetry, step down and emergency, where five-year cumulative turnover reached 117.8%, 115.4% and 113.6%. Med-surg is not far behind: at 18.1% annual turnover it runs above the 17.6% national average.
A unit that replaces its entire staff inside five years cannot run on apprenticeship. There is no stable senior cohort for the knowledge to live in.

When the junior end of a unit turns over continuously, juniors end up precepting juniors. The tacit knowledge that never reaches a chart — I don't like how this patient looks — walks out faster than it can be handed on. The cost shows up twice: as risk at the bedside, and as the specific burnout of never feeling competent.
And the gap stays open a long time. A vacant med-surg RN post takes 83 days to fill — above the 78-day national average — so the unit absorbs the missing experience for nearly three months before a replacement even starts orienting.
What We're Building
Noria already sits in the nursing workflow, reading the chart and capturing voice notes. That position lets it do something no standalone education tool can.
Scaffolding at the moment of need
Built — in the demo today
When a patient needs a procedure the unit has a policy for, Noria surfaces the hospital's own approved protocol alongside vitals and meds — cited to source, the same way every Epic-derived claim is. Noria never writes clinical guidance; it retrieves yours.
Experience-matched assignment
In design — charge-nurse view
Charge nurses assign by gut and availability, because that is all they have. Noria can offer an advisory view built from what nurses have actually charted — not self-assessment — so a stretch assignment is a deliberate choice with support attached, rather than an accident.
What This Will Never Be
A system that reasons about a nurse's experience could very easily become a system that ranks nurses. We think that product would deserve to fail, and it would be killed on the unit within a week. So the constraints came first, before the feature:
It never tells a nurse they are inexperienced.
No "new for you" labels, no competency scores, no graduation or student framing. Support is framed as a resource — "Protocol", "Reference" — identical to what every other nurse sees.
Nobody over their shoulder can tell.
If the system adjusts anything, it adjusts prominence, invisibly. A nurse is never told why something surfaced, and the screen looks the same to a colleague walking past.
It is not a manager scorecard.
The record belongs to the nurse, not the unit. The moment this becomes a surveillance input for performance review, it stops being a tool nurses will accept — and rightly becomes a labor issue.
It never invents clinical guidance.
Noria retrieves and cites the hospital’s approved protocol. It does not author medical content, and it shows its source every time.
Where This Actually Stands
The protocol scaffolding is built and running in our demo. The charge-nurse assignment view exists as a working read-only prototype. Neither has been through a pilot, and we have not measured an outcome from either yet — this page describes a direction we are committing to publicly, not results we are claiming.
If you run a med-surg unit and this describes a problem you have, we'd like to build it with you.
