Case Study

RPM platform from 0 to 1 and beyond

CareTrust is an RPM and patient engagement platform purpose-built for remote care programs. It connects patients to their care teams through Bluetooth-enabled vital sign collection, patient-reported outcomes, secure messaging, and intelligent engagement mechanics — delivered through a native mobile app or SMS, meeting patients wherever they are.

The Situation

At Adnab Research, the clinical team set out to build a remote patient monitoring platform from the ground up to extend its population health services. From the start, the focus was on HIPAA compliant, secure infrastructure. Over time, the vision expanded to a flexible patient engagement platform capable of supporting diverse workflows, driving sustained patient adherence, and operating as an API first system for seamless integration with external cloud platforms.

Phase 1 — Build an MVP

Service: Product Build · 0→1

Challenge: Define and ship a first working version of a patient engagement platform capable of Bluetooth vital sign collection, patient-reported outcomes, and questionnaire delivery — across both iOS and Android.

Approach: Defined the full product requirements. Recruited, hired, and led the engineering team. Selected a cross-platform mobile stack to maximize velocity and eliminate platform fragmentation. Led delivery end-to-end through the first production release.

Outcomes:

Working iOS/Android app with BLE device integration
Pulse oximeter, blood pressure monitor, and weight scale connected
PRO collection and questionnaire delivery live
Foundational patient UX shipped

Phase 2 — Platform Expansion

Service: Product Strategy · Scale

Challenge: A single-channel mobile app left behind patients with limited smartphone access and left high-value clinical features — engagement, communication, intelligence — entirely on the table.

Approach: Expanded to SMS delivery for low-touch programs. Added HIPAA-compliant secure chat between patients and care teams. Introduced a gamification layer to drive sustained engagement. Built AI-generated reports to turn collected patient data into actionable clinical intelligence.

Outcomes:

Multi-modal platform: app and SMS serving any patient population
Secure messaging live for care team communication
Gamification mechanics driving measurable engagement lift
AI report generation turning passive data into clinical insight

Phase 3 — Integration Strategy

Service: Platform Architecture · API-First

Challenge: CareTrust was collecting valuable patient data but operating as an island. Care teams needed that data flowing into systems they already worked in. The platform needed to extend beyond vitals into the full patient journey.

Approach: Built a comprehensive API layer enabling bidirectional data exchange with external platforms, EHRs, and analytics systems. Extended the platform's use case surface to include appointment management and scheduling, transforming CareTrust from a data collection tool into a full patient engagement infrastructure layer.

Outcomes:

REST API layer enabling third-party system integrations
Appointment management and scheduling capabilities live
CareTrust positioned as infrastructure, not a point solution
Data flowing bidirectionally across the care ecosystem

Note: What started as a focused MVP became a platform strategy — one built to expand in every direction: more modalities, more clinical programs, more integrations. The decision to build cross-platform from day one, and API-first by phase three, meant CareTrust could operate as infrastructure rather than just another point solution in an already crowded remote care market.
