Our Client

Global health-tech leader with a bedside wound-care mobile app used by frontline nurses.

Challenges

  • Evaluations took ~14 minutes per wound using paper rulers and manual forms.

  • Variability across clinicians/lighting reduced accuracy; re-keying into EHR slowed throughput.

  • Mandate: embed AI into the existing mobile app—no extra steps, no double entry.

What We Delivered

  • Vision Model (12M+ labeled wound datapoints): Robust edge detection and auto-calibration via reference marker for consistent measurements.

  • On-Device Inference: TensorFlow Lite on iOS/Android (<200 ms, offline) to keep latency predictable and attention on the patient.

  • FHIR-Native Integration: Write images, dimensions, and notes directly to Epic/Cerner/MEDITECH; no double entry; full audit trail; HIPAA/GDPR controls.

  • Deployment at Scale: SDK packaging + MDM rollout; zero production downtime.

Results

  • –79% evaluation time: 14 → 3 minutes per wound; nurses reclaimed ~1 hour/shift.

  • 95% measurement accuracy vs. laser ruler (N = 1,200 images).

  • Consistency: Standardized measurements now support value-based care metrics and insurer audits.

  • Early Insight: Longitudinal data flags stalled wounds 7 days sooner for proactive intervention.
