Nemours App

The cross-platform, multilingual patient portal developed by Nemours Children’s Health.

Overview

ABOUT THE APP

AGILE DEVELOPMENT

AGILE DEVELOPMENT

Patient families use the Nemours app to schedule appointments, communicate with their care team, have video visits, view test results and much more. Users can securely access medical records, health tools and educational resources.

AGILE DEVELOPMENT

The cross-functional team follows an iterative approach to discover issues and opportunities, define a project, develop ideas and deliver solutions. I collaborate with stakeholders from business, clinical, engineering and marketing.

9 members of a project team

At the beginning of a project about virtual check-in, we met with stakeholders to learn relevant information and assess the current situation. After these conversations, we had a better understanding of the problem, goals, objectives, project scope and next steps.

CONTEXTUAL INQUIRY

Research output shows the patient experience of arriving at the hospital

For this project, I did a field study to observe the ‘context of use’ and ask questions about relevant processes. This research output visualizes the current experience of arriving at the hospital and details the organization’s actions at each step of check-in.

UX competitive analysis shows 8 screenshots from competitors

Before working on task flows, I do secondary UX research to evaluate similar offerings by other hospitals and identify opportunities for design.

I then explore a range of options to present to stakeholders and share with the app team. After receiving feedback, concepts are fleshed out.

Usability Methods

PERSONAS

MODERATED TESTING

PROTOTYPING

Personas are co-created with stakeholders. We leverage them when discussing use-case scenarios to ensure diverse perspectives are being considered.

The results of preference testing between 3 design options

High-fidelity interactive prototypes are created in Figma. We often do preference testing to see which option users prefer and why.

Sample page from usability report

During usability sessions, participants are asked to think aloud as they complete a series of tasks using either a prototype or test account.

Sample results from a task on usertesting.com

The human insight platform is utilized to quickly get feedback from contributors. I develop test plans, build tests, analyze results, create reports, and share findings with stakeholders.

ITERATIVE DESIGN

UI designs before and after usability testing

This example, from a health tool for obesity, shows how user feedback informed the design. An iterative process allows us to quickly make changes and refinements before developer handoff.

CARD SORTING

Example of results from card sorting

This method is employed to continuously improve the app’s information architecture. It helps us determine how to intuitively organize content and identify common language.

The Impact

RESULTS

A human-centered approach to design has resulted in a widely-used mHealth app. Since the Nemours app launched in 2020, enrollment in the patient portal has steadily grown from 25% to 80%. It has consistently maintained high ratings—4.9 in the App Store and 4.8 on Google Play. Researchers have published articles and given presentations about several of the mobile health tools and interventions available in the app. Most importantly, it has helped families in Florida and the Delaware Valley manage care for over 500,000 children.
