HypoMap

HypoMap

 

Overview

A novel, patented, system for identifying hypoglycemic unawareness in patients. Through creating a simple way for patients to document their symptoms the HypoMap system allows doctors to identify diabetes patients who exhibit moderate to acute hypoglycemic unawareness like never before.

Responsibilities
I was the Lead Designer on this project and responsible for wires, user testing, prototyping, and all design. I worked alongside one Product Manager to make sure all goals were reached.

 

Three Goals

 

Patient & Doctor Flows

Working closely with Joslin Diabetes Center we were able to rely on their deep wealth of knowledge regarding current hypoglycemia diagnosis techniques and treatment plans. Using this research the Product Manager and I sat down and hammered out a basic flow of what a new hypoglycemia treatment would look like. 

 
 

1st Appointment
In this step of the process the doctor identifies several hypoglycemia events with the patient. The doctor prescribes HypoMap to the patient using some of our marketing collateral that guides the patient through the process of either becoming a new Glooko user or adding the HypoMap to their existing account.

Monitoring Period
Once the patient is up and running with the Glooko app and syncing their meter with Glooko all they have to do is log some information into the app every time they're hypoglycemic. Using the Glooko Web Platform the doctor always has access to a patients data as it's entered into the app. The length of the monitoring period is determined by the doctor.

2nd Appointment
After the monitoring period is over the patient and doctor either meet in person or over the phone to discuss the results. This is where the HypoMap web views come in. They take all the patient reports and create simple visualizations to identify hypoglycemic unawareness, frequency of events, and any patterns around their events. 

 

App Wires

We focused on solving two main problems with the app. Prompting people to complete a hypo report when we detect low blood sugar and making completing a report a breeze. 

 
 

Sync Prompt
When the patient syncs their meter with Glooko they get a notification of all the hypo events they have had. This leads the user to the HypoMap section of their Glooko App where they can fill out a Hypo report.

 
 

Hypo Report
After selecting a particular hypo event a patient can fill out a hypo report that goes through the symptoms, causes, and treatments for each hypo event.

 

Web Wires

I started with the base data we needed to display: blood glucose, symptoms, causes, treatments and time. Using this data and hierarchy of needs I gleaned from talks with several doctors I put together basic wires of how to display this information.

 

Awareness
Hypo symptoms are ranked from least to most severe along the x-axis while glucose is listed along the y-axis. The ability to link symptoms to glucose levels in a heat map view presents the information in the simplest way possible.

Reports This view will act as the full breakdown of all data from each report filled out by the patient and all hypo events as well.

Patterns The patterns view highlights hypo events on a calendar by the time of day that they occurred. This is important for patients the have specific off days or have events occur more often at a particular time. Evenings being the most dangerous.

User Feedback

After getting everyone on the team to agree on the wires I mocked up a quick version of the web views and a version of the mobile app in InVision. From now on when the Product Manager and I ran user testing we would have something concrete to show and get feedback on. We followed a weekly feedback schedule with nurses, and doctors  from Joslin Clinic to make sure the web product was headed in the right direction. We also ran parallel feedback sessions with current Glooko users at our office with the InVision prototype.

 
 

User Learnings

 

RESULTS

 

Mobile

Sync Popup, HypoMap Home and Hypo Event User app journey starts with syncing their device. This is where we detect if they have had any hypo events and notify them. A section within the app is designated for hypo events where the user can see past events and how many reports they have filled out. If a hypo event consists of more than one reading, selecting that event will bring up the Hypo Event screen where the user can see how many hypo readings this report will encompass.

Symptoms, Information, Causes The report screens have an emphasis on simplicity, selecting the icons that relate to their condition and moving on. The question mark at the top right serves to inform about the section.

Treatment, Require Assistance, Summary The treatment section includes an extra step where the user can select if they required any assistance which in the doctor platform is a major red flag that needs to be discussed with the patient. The final section is a summary page where the user can see everything they entered, and if they choose to edit any part of it.

Web Platform

  Awareness This is the star view, a heat map that mixes blood glucose events with ranked hypoglycemia symptoms to clearly show at what point a patient is feeling their hypoglycemia. Someone in the top left of the heat map will have good hypoglycemia awareness while someone in the bottom right will be in real trouble. Having low blood glucose while not feeling symptoms can be deadly.

Full Report This view encompasses all the data coming from the user reports but it's main function is to bucket events by time of day. Over night hypoglycemia events are the most dangerous and in this view they appear at the top of the list. Users can also see a quick graph of each hypoglycemia event and the events surrounding it by clicking on the graph in the top right of each event.

  Calendar A simple yet powerful view that shows the time of day that hypoglycemia events occur over the span of a month. An easy way of spotting patterns this view is the predecessor to later projects where we start to really hone in on patterns and algorithms to identify them.

Key Learning

Personal

Everyone is part of the solution
Having only one clinic providing the majority of the feedback proved to be a hindrance to mass adoption. Every clinic & health care provider has a method, a unifying method would include them in the conversation.

Company

Stop the creep
A successful product cycle must be setup to identify and prevent scope creep . Setting hard stop dates on project features while prioritizing a more iterative process minimizes resource waste and unproven solutions.
