Patient App: Scheduling, Intake & Messaging
The outpatient network’s call center was buried in rescheduling calls and simple status questions. Paper intake arrived incomplete, which delayed appointments and frustrated clinical staff. Patients expect the ease of consumer apps, but leadership was not ready to replace the electronic health record (EHR)—only to improve what surrounds it.
Business impact at a glance.
Completed digital pre-visit intake rose by 36% compared to the prior web-only flow.
No-show rate for digitized appointment types decreased by 19%.
Call center volume for “when is my appointment” style inquiries fell by an estimated 14%.
Patient app store ratings stabilized above 4.3 after three post-launch iterations.
Clinical staff reported faster rooming when intake arrived complete.
Business Challenge
- Scheduling interfaces to the EHR varied by site and could not sustain high-volume mobile traffic without throttling.
- Patients abandoned long questionnaires on small screens before finishing.
- Care teams wanted secure messaging without exposing the full medical chart on a phone.
- The app had to work well with large text, screen readers, and older adults with varying dexterity.
- Compliance required audit trails and the minimum patient data on the device necessary for each task.
Our Approach
We shipped a single Flutter codebase for iOS and Android, integrated through the client’s existing integration hub (middleware)—not by writing directly from the app into the EHR. Pre-visit steps were broken into short, save-and-resume flows. Push notifications opened the right appointment screen; message retention followed clinical policy on the server. We tested with real patient cohorts and refined language, layout, and touch targets before wider clinic rollout.
Phase 01
Discovery & alignment
Workshops, process and systems review, success metrics.
Phase 02
Design & planning
Architecture, experience and workflow design, delivery plan.
Phase 03
Build & validation
Implementation, integration, testing, demos, refinements.
Phase 04
Go-live & enablement
Controlled rollout, training, handover, post-launch tuning.
What We Delivered
- Built appointment list, reschedule requests, and calendar exports.
- Implemented guided pre-visit questionnaires with validation and EHR handoff.
- Added secure in-app messaging with role-based visibility.
- Integrated proxy PDF viewers for lab letters with watermarking.
- Localized key flows for two primary languages used in the service area.
- Established release cadence with phased clinic rollout and training videos.
Technology Stack
Patients actually finish the forms before they arrive. That single change saved our front desk hours every week.
