How this project came up
Information fragmentation in healthcare is one of the leading underlying causes for problems such as misdiagnoses, data loss, incorrect medications, legal issues and fraud [1]. The problems also escalate when patients do not have control over their own personal health information. In 2020, the US Department of Health and Human Services (HHS) established rules that would provide patients safe, secure access to their health data while letting them opt to share to big tech or other [2, 3].
Introducing MediLinker
Ideated by Dell Medical School, MediLinker is a digital health wallet that enables patients to manage health records, medication and insurance through blockchain.
Goal
The client, Dell Medical School was interested in:
understanding how their app fits in with the competitor space
understanding if it provides value to their customers
exploring design improvements to better assist potential users

Overview
The goal of MediLinker is to develop an electronic health identity management system that bridges fragmented data silos to form a patient-centric health record using blockchain technology.Similar to the concept of a 'digital wallet', MediLinker enables its users to manage and control their health records, medical and insurance information.

Process
Client Kickoff
OBJECTIVE:
Design to assist better understanding and adoption of Blockchain based Digital Health Wallet
WAYS TO ACHIEVE THAT:
1. Comfortability wIth Blockchain and digitizing health information
Ensure users feel comfortable with Blockchain and digitizing health information
2. Security, Transparency, Privacy = Trust
Prioritize security, transparency and privacy to gain users’s trust
3. Help
Better onboarding, tutorials can provide workflows to help and enable user understanding,

Heuristic Evaluation
Heuristic Evaluation was used to identify usability problems so that it can be addressed in the next iteration of the UI design.
Usability was measured based on Jakob Nielsen's 10 Heuristics.
A severity level from 1-4 was established to identify the most serious problem in order to allocate resources, time and effort to address it.
Competitive Analysis
Competitive Analysis was done as part of the initial research to identify the competition and understand their current practices, strengths and weaknesses.
This would help identify MediLinker's key differentiators that would make it stand out from its competition and improvement areas as well. The competition was divided into 4 levels.
Kano Model
The insights from the Competition Analysis was presented to the client as a Kano Model. Kano Model was used as it provides a plan by prioritizing features depending on user satisfaction and the current level of its implementation.
The Kano Model analysis is categorized as:
Must-Haves: These are features that users expect to see, and therefore, the design must have
Performance: Also known as 'Satisfiers', these features can increase user satisfaction. The more 'performance/satisfier' features, the better.
Delighters: Also known as 'Excitement', these features that users don't expect to see (unavailable from competition) which can influence the users' level of satisfaction.
App Redesign
Upon considering the recommendations from the Competitive Analysis and Heuristic Evaluation, the client's design team updated their design as shown below.
