How it works
One pipeline, from a quiet lab trend to a coordinated nephrology visit.
Springbox doesn't ask a primary care team to do anything new. It watches the data that already flows through the EHR, does the administrative work a referral usually gets stuck on, and keeps a human care coordinator in the loop the whole way.
The five stages
What actually happens at each step.
EHR signals, read continuously
Springbox connects to the EHR's existing data feed — serum creatinine and eGFR trends, urine albumin-creatinine ratio (uACR), diagnosis codes, medications, and risk factors like diabetes and hypertension. Nothing is entered by hand, and nothing changes about how a visit is documented.
An AI risk model built for CKD trajectory
The model looks for the pattern that matters clinically: not a single low eGFR reading, but a trend, combined with albuminuria and risk factors, that maps to a KDIGO risk category. It's tuned to flag patients who are heading toward stage 3b–4 CKD, not just those already there.
A one-click flag inside the PCP's workflow
A flagged patient shows up as a review item in the clinician's existing inbox, with the supporting labs and trend already summarized. Confirming it takes one click — there's no separate risk dashboard to check.
Prior authorization, drafted automatically
Once confirmed, Springbox assembles the prior-authorization packet against the patient's payer rules — diagnosis codes, supporting labs, and medical necessity documentation — so the referral isn't stuck behind paperwork the practice has to build from scratch.
A matched, coordinated nephrology referral
The referral goes out to a nephrology practice with capacity and network fit, records attached. A Springbox care coordinator helps the patient get scheduled and understand what to expect.
A loop, not a hand-off
Updates from the nephrology visit — and ongoing labs afterward — flow back into the primary care record, so the PCP stays informed and the risk model keeps learning from what actually happened.
Why the timing matters
KDIGO's CKD guideline points to an eGFR below 30 mL/min/1.73m² — or a faster-than-expected decline, or a very-high-risk category on the KDIGO heat map — as the point to involve nephrology. Reaching that point earlier gives a care team more room to slow progression, manage anemia and mineral bone disease, and plan ahead instead of reacting to a crisis. Springbox is built to surface that moment as early as the data allows, not wait for it to become unmissable.
