Background Story

This is a hackathon project.

I joined a Samsung B2B 3-day hackathon in Seattle. We were tasked to team up with attendees on the spot and teams must be composed of atleast 1 designer, 1 developer and 1 project manager. Once the team is formed, we had to choose the project we want to work on based on the pre-set enterprise projects Samsung prepared. Due to the medical background of both I & another teammate, we decided to take a healthcare project. Because it was a Samsung event, we were required to use their technologies both hardware (Samsung Galaxy Note 10) and software including DeX & Knox.

I was the dedicated designer of the team, and our entry won the Most Original/ Inventive UX/ UI.

The Challenge

Electronic Visit Verification

What’s the customer need?
The Cures Act mandates all Medicaid personal care services must implement electronic visit verification (EVV) for in-home visits by January 2020. And all home health services must meet the same mandate by January 2023. Agencies need to implement a solution that is in place, on time, cost-effective, and efficient.

Target customer
- Personal homecare agencies

Target audience
- Owner
- General Manager
- Procurement
- Finance Director

Customer pain points
- Completing the EVV process in real-time
- The need for a low-cost, reliable solution.

Research



Since this is only a 3-day project, we didn’t have the luxury of doing an extensive research. We forego user survey and interviews, and instead turn to online research, and to my personal experience as a nurse. The best online source we found was a Youtube video of a home health nurse detailing her usual routine when visiting patients.

Top takeaways from the video:

  1. Home caregivers are mandated to use a form called Form 485 -- a document that contains all the info the care providers need to know when visiting a patient.
  2. Some home care providers still use pen and paper when documenting their visits.
  3. It’s quite common for care providers to delay charting their visits hours or days after they're completed.

User Personas



Celia

27, F
Registered Nurse

Goals:

  1. Find an easier way to document visit.
  2. Make everything available online.
  3. Centralized source of patient information.

Frustrations:
  1. Too many paperworks to file and track.
  2. Lack of access to other care provider’s documentation.
  3. No real-time feedback on approval of visit.



Deanna

48, F
Nurse Manager

Goals:

  1. Easy delegation of assignments.
  2. Better supervision of care providers.
  3. Being able to work even not in front of the desktop computer.
Frustrations:
  1. Decentralized system for delegation and approval of visits.
  2. Having to learn and navigate different softwares.
  3. Not being able to work on the go.



Competitive Analysis

Because all existing EVV’s need a member’s login, we weren't able to get into any of them to play around to investigate further. We had to completely rely on the previews in the app store and random online images. These are some of the wireframes I found from few companies.

Strengths:
  1. Shows list of all upcoming visits
  2. Has patient's vital info
  3. Allows signature capture

Weaknesses:
  1. Burdensome onboarding
  2. Outdated interface
  3. Inconsistent menu

Information Architecture



User Stories

Due to time constraints, we decided to design only for new visit experience. Meaning a nurse who had previously visited other patients but is visiting a new patient. Here are our assumptions for the design.

User #1: Nurse / Care Provider
  1. Already registered in the system
  2. Visiting a new patient for the first time

User #2: Manager
  1. Already registered in the system
  2. Logging in to check the visit details and approve the completion of the visit.

User #3: Patient (Part-time user)
  1. Owns a patient ID with an NFC capability
  2. Physically capable of providing signature

As a care provider I want to ...
  • Easily and securely sign in
  • See my upcoming visits
  • Conveniently pull up my patient's contact info & location
  • See my patient's records in app
  • Document on the fly.
  • Submit my report at the end of my shift
As a manager I want to ...
  • Easily and securely sign in
  • See all my urgent and important tasks in one glance
  • Assign patients to care providers
  • Review and approved completed visits
  • Be able to work away from my desk
As a patient I want to ...
  • Be assured my care provider knows all the important info about me
  • Make sure I'm getting the right treatment
  • Keep my privacy protected
  • Be billed only for completed visits and necesssary treatments
  • Know that my care providers properly coordinate with each other

User Flows

For the sake of preventing fraud - the main purpose of EVV, there were 2 main user flows for this app:

  1. Care Provider
  2. Manager
For the Care Provider, the main tasks are:
  1. Sign in
  2. Start client visit
  3. Verify client’s medical record and plan of care of the particular visit
  4. Perform and document care
  5. Verify care provided
  6. End shift & submit report for approval
For the Manager, the main tasks are:
  1. Sign in
  2. Review visit details.
  3. Approve completion of visit.

Wireframes

I did a very quick pen and paper low fidelity wireframe and presented it to the team for critique and input. Since I did most of the research and they trusted me due to my authority in the nursing field, they actually didn’t do much critiquing. I think it’s an inherent limitation of hackathons of this kind due to the limited time and manpower teams have. If this was a real-world project, I would have consulted authorities in the field to check the strengths and weaknesses of the design and iterate before moving into high fidelity wireframes.

We also skipped lo-fi wireframe testing for the same reason, and jump right into hi-fi wireframes.

Branding



Brand Name & Logo

The name & logo weren’t part of the judging criteria so we didn’t spend any time brainstorming on it. When the event ended, we still didn’t have a name or logo for our product. The name and logo you see now are my additions post-competition.

Like my other projects, I want the name to be short and easily identifiable with the product- Home Health was the obvious choice.

As with the logo, I aimed for a basic-looking and straightforward logo with the silhouette of a house and the cross associated with medical facilities.

Color

Red for healthcare.
Orange for wellness.

I also chose to utilize a spectrum of different colors as an identifier of each tab of the medical forms, reminiscent of a well-designed filing drawer. This way it’s easier for caregivers to sort the list of text heavy pages.

As part of proper & complete client record verification, each tab’s background color lightens indicating that the tab has been opened already. This provides a visual cue for the caregiver to make sure they had not skip a section.

In addition, the font weight becomes slightly heavier on the lighter background to achieve better contrast.



Typography

Samsung runs on Android so we used Google’s Material Design guidelines for the typography. We used Roboto for the main typeface and Lato for the headings.

Lato was chosen due to its semi-rounded details that gives a feeling of warmth, while its strong structure provides stability and seriousness.

Visual Design



Mockups & Preference Tests

Again, due to time constraints, I decided to reuse the Android UI I already have from a previous project. I adopted the branding colors of red and orange but decided to be more playful and use gradients instead of solid colors. This gave the product a more modern look.

For the preference tests, I did a quick guerilla test among my teammates. This is one of the screens they asked a revision for and the redesign I made.

Testing & Conclusion



All of our tests were conducted among the members of our team. Everyone navigated the prototype without a problem. Unfortunately, but quite expected with our timeline, we weren’t able to make the product fully functional. Out of all the necessary codes we needed to make, we were only successful at making the timestamp appear after the NFC device was tap on the Samsung Note 10.

Despite that, we still won the Most Original and Inventive UX/UI award.

Key Takeaways

I really enjoyed designing Home Health. As a nurse, it’s a goal of mine to design a healthcare product. The hackathon experience was eye-opening because it was the first time I had to work with a team to build a product. It gave me a more holistic view of the roles of each member and how different front-end and back-end development are.

As per the user interface itself, I am happy on how it turned out especially for something built in just 3 days. Given that I reused most of my elements from previous projects, I realized how big of a difference a library can make for decision making and speed of building overall. I didn’t need to make the tiny decisions on text sizing, spacing, drop shadows, etc. Instead, I was able to focus on the big picture- the vital data that needs to be present in the app, the security measures, how to address the customer's pain points.

If I can do it all over again, I would have done an extensive research. I would interview home healthcare providers, their managers, and other stakeholders. I’d make sure to consult with them throughout the whole process - all the way to user testing. Also, I would have studied the laws governing the healthcare space including HIPAA.

As a Samsung product, I would design an interface compatible with their DeX station so users can have a seamless experience on both mobile and desktop screens. I would incorporate more ways that can leverage the Samsung ecosystem.
