The Clinical Challenge

Why global renal care is failing to scale

850M

Patients worldwide living with chronic kidney disease

ISN/Global Atlas

60%

The Clinical Gap

Data Blind Spots

Generic databases ignore renal-toxic additives

Analysis: Up to 1000mg hidden phosphorus/day

Static Protocols

One-size-fits-all limits fail CKD progression

Analysis: 40% of patients exceed safety limits

Lab Disconnect

No integration with real-time lab results

Analysis: Critical latencies in dietary adjustment

Zero Portability

Offline functionality is absent in clinics

Analysis: Care gaps in resource-limited settings

Safety Watchdog

Elite Clinical Safety Watchdog

An autonomous inference engine that monitors every entry against established renal protocols.

Rule Logic: Potassium Safety Protocol

IF (Serum K > 5.5 mmol/L) THEN Limit = 2000mg ELSE IF (CKD Stage >= 4) THEN Limit = 2500mg ELSE Limit = CalculateByWeight(IBW, Dialysis)

The system triggers proactive overrides when lab results deviate from baseline safe zones.

Dynamic Logic: Rules adapt to your CKD-EPI stage changes
Lab Integration: Alerts trigger when diet conflicts with recent labs
Medical Precision: Corrected Calcium and AjBW formulas included

Clinical Inference Logic

Deterministic priority-based nutritional orchestration

The Renal Companion CDSS utilizes a multi-layered deterministic inference engine to resolve complex nutritional constraints in real-time, ensuring absolute patient safety and guideline adherence.

Baseline Calibration

Calculation of IBW (Hamwi) and CKD-EPI (2021) eGFR to establish the patient's biological ceiling.

Priority Resolution

Clinical rules are cross-referenced against comorbidities. Higher priority protocols dynamically override chronic baselines.

Lab Feedback Loop

Real-time calibration based on biomarkers. Serum K > 5.5 or Na > 145 triggers immediate proactive safety caps.

Predictive Biomarker Mapping

Academic-grade trend analysis and metabolic modeling

Leveraging sophisticated mathematical models to monitor disease progression and metabolic load.

Linear Regression Trends

90-day trajectory mapping of GFR and Creatinine to detect 'Rapid Decline'.

Metabolic Acidosis Modeling

Dynamic calculation of PRAL (Potential Renal Acid Load) scores to prevent diet-induced complications.

slope = (n∑XY - ∑X∑Y) / (n∑X² - (∑X)²)
