Stroke Connect

Reducing Time-to-Treatment for Stroke Patients

Reducing Time-to-Treatment for Stroke Patients

At a Glance

Stroke Connect is a clinical collaboration platform designed to connect pre-hospital stroke assessment with in-hospital decision-making. This system is integrated into mobile stroke units (ambulances equipped with CT machines) and hospital systems. It enables real-time data sharing, guided workflows, and remote expert collaboration to reduce time-to-treatment in acute stroke cases.

Process Followed

Design Thinking Framework + Linear Design Process

Analysis of user research insights -> Design thinking workshops -> Ideation -> Validation -> Iteration -> Mobile-desktop harmonization

Role & Responsibilities

My work focused on interaction design across mobile and desktop platforms, ensuring usability, consistency, and harmonization within a regulated medical environment, while supporting users with very different professional backgrounds.

Aim

Stroke Connect’s digital workflows aim to standardize and accelerate clinical decision-making during the most critical phase of care.

Team at Work

This project was both exciting and challenging at the same time. Collaborations took place between product and engineering teams to discuss GTM strategies and UX priorities. Deep domain research and expert discussions were done to understand regulatory constraints.

Involved

A small team of two interaction designers and a visual designer was working on the collaboration module for Stroke Connect

Project Scope & Context

Stroke care is designed for an extremely time-sensitive workflow. Every minute without treatment for the patient increases brain damage and worsens outcomes.

Key Challenges

Data Silos

Information black box between ambulance teams, radiologists, neurologists, and hospital systems

Delayed Clinical Decision

Lack of real-time insights in pre-hospital care settings

Variability in Clinician Workflows

Personas of multiple stakeholders with different medical professions and workflows

Research KPI

Reduce time-to-treatment for patients with a heart stroke

UX Role & Contributions

1. Design challenge

How might we create a user experience that enables clinicians to rapidly and confidently document, review, and communicate clinical assessments in time-critical, high-stress environments?

User groups:

  • Physicians

  • Paramedics

Context of use:

  • On-scene emergency settings

  • Ambulance environment

  • Remote consultation between hospital and field teams

2. User Research Insights

Conducted several field studies, qualitative and quantitative interviews

3. UX Strategy & Design Principles

Based on research, core design principles include:

  • Clarity over complexity: Simplify data entry and reduce unnecessary UI elements during time-critical tasks.

  • Contextual guidance: Provide task-based workflows with embedded help.

  • Real-time communication: Integrate chat, video, and alerts directly into the patient data view.

  • Responsiveness under constraints: Ensure performance even in low-bandwidth environments.

4. Interaction & Interface Design

See Design

UX deliverables:

  • Prototype demonstrating guided NIHSS assessment

  • Real-time image and data sharing screen

  • Usability flows for mobile and desktop interactions

  • Accessibility considerations for field usage

  1. Heuristic Evaluation

I conducted heuristic evaluations using 10 usability heuristics, resulting in:

  • Identification of interaction risks

  • Simplification of complex flows

  • Improved clarity around critical actions and states

Outcome & Impact

Delivered interaction concepts that support fast, safe clinical decision-making

  • Reduce time-to-treatment by ~30 minutes

  • Patient recovery outcomes improve by up to ~65% compared to standard care pathways.

  • Enhanced clinician confidence in remote stroke assessment

  • Reduced cognitive load during high-pressure clinical documentation

  • Improved collaboration between field teams and hospital specialists
