12 / day
house calls per physician, optimally routed
Case study · House-call clinic
House-call routing for 12 patients/day — across multiple doctors, with EHR sync.
A US clinic running daily house calls needed a routing system that didn't fall apart. Administrators were manually planning routes for multiple doctors visiting up to 12 patients a day at homes, nursing facilities, and hospitals. We built a custom admin platform plus a PWA for doctors with offline caching, route optimization, and EHR sync.

The challenge
Three problems — all at once.
Administrators were assigning each doctor up to 12 patients daily for house calls — but planning was manual, time-consuming, and error-prone.
Integration with existing EHRs was non-negotiable. Patient medical history, diagnoses, medications, treatment plans, immunizations, allergies, imaging, and lab results all had to sync from other providers' systems.
Doctors needed to work in the field — at homes, in nursing facilities, in hospitals — often with patchy or no network. The application had to function offline and still produce accurate route optimization.
What we did
Seven specific things.
- 01Built an admin panel with mini-CRM + PHI handling: patient and doctor management, schedule creation, role-based access (Super Admin, Admin, Doctor)
- 02Encrypted PHI on the server with EHR-sync flows accepting both manual entry and system import
- 03Built a PWA for physicians — daily routes, patient history, schedule visible weeks ahead, with full offline operation and cache-first sync
- 04Created the route-optimization scheduler: factors in call frequency (biweekly, weekly, specific days), 12-patient-per-day cap, location coordinates, and distance calculations via Google Maps
- 05Added multi-format clinical notes — text, audio, voice-to-text — so doctors can document in their hands-free workflow
- 06Delivered 10 admin reports: Missed Patients, Completed Visits, Audio Notes, Provider Summary, Referral Census, Referrals, Routes, New Patients, Documents, Weekly Route Overview
- 07Released features gradually so the clinic's end-users could test as the product evolved
