Overview
Micromed is a leading player in cardiology in Brazil. This project involved the complete replacement of the legacy Thundera platform with a new workstation for medical reports. The goal was to modernize the technology and, most importantly, to solve critical usability issues that impacted medical efficiency.

The Challenge
In cardiology, "time is muscle". Doctors deal with thousands of exams daily, and every second saved in the reporting process directly impacts patient response time.
The Problem
The previous platform presented:
- Legacy Technology: Difficulty and high cost to implement improvements.
- Workflow Friction: An average of 6 clicks to perform a simple report.
- Cognitive Load: Outdated interface, making it difficult to prioritize critical exams.
- Instability: Frequent logouts required repetitive authentication workflows.
Key Metric: Reduce the average reporting time while maintaining clinical safety.

Discovery Process
We began with a deep dive into the telemedicine ecosystem, visiting and interviewing doctors at reference institutions: Albert Einstein, Beneficência Portuguesa (BP), InCor, and Samaritano.

Some key Insights
- The Continuous Flow: Doctors desired an automatic "next exam" dynamic, without having to return to the main list.
- Critical Data: Information such as Age, Sex, and Heart Rate are fundamental for interpretation and needed greater prominence.
- The "Tigrão Doctor": Experienced doctor profile seeking extreme speed; for them, the system should be as agile and direct as possible.

The solution
We designed the new workstation focusing on performance, clarity, and predictability.
Pillars of the New Interface
- Click Optimization: Drastic reduction in steps for submitting normal reports (higher volume).
- Visual Hierarchy: Patient data and ECG tracing gained prominence, with enhanced zoom tools.
- High-Demand Workflow: Implementation of the sequential reporting mode to optimize work in large centers.
- Pre-analysis AI: Training and implementation of Micromed's own AI for screening exams and ordering worklists.

Validation and Iteration
To ensure the effectiveness of the solution, we conducted rigorous testing cycles:

Success Metrics: Application of the SUS (System Usability Scale) questionnaire to measure usability perception.

Design Adjustments:
Design Adjustments: We refined the ready-made phrase box and the signaling of exams with interference after feedback from tests.
Beta Test: Controlled launch at Beneficência Portuguesa for validation in a real, high-pressure environment.

Beta Test
The beta test was conducted with cardiologists at Beneficência Portuguesa, comparing the previous platform with the new Workstation.
The results validated the core goal of the project: significantly reducing report turnaround time.
