Mayo Clinic Decision Aid
In spring 2016, Mayo Clinic partnered with Georgia Tech to redesign printed depression medication decision aids. The goal was to prototype a digital decision aiding tool to help doctors facilitate conversations that are positive and constructive when treating patients with depression.
The iPad was selected as our target device for its accessibility — doctors can easily hand it over to patients for view; additionally, there is the ease of potentially user-testing prototypes by deploying iPads in existing Mayo Clinic patient rooms. My project team delivered a Keynote prototype to demonstrate key features, and documented each steps of the process for discussion and iteration purposes. To understand user requirements, Mayo Clinic shared 3 private videos to show us the scenarios of use for the existing paper decision-making aids.
Mayo Clinic presented 13 medications to treat depression, each with their own pros and cons.
The Decision Aid
The existing decision aid (DA) provides evidence-based information about depression medication options and their characteristics to help patients take part in the decision making process during their visit at Mayo Clinic.
However, clinicians decides how and when to use, and may not elect to use the DA; typically 3-4 cards are used.
Designers at Mayo Clinic's Research Unit hosted conference calls to brief the project context, and provided 3 private videos that showed how the paper DA is used.
To understand the experience more deeply, I mapped out the associated emotions in each step of the decision-making process during a clinical visit.
A patient may start out depressed, and frown at the need to understand medicinal context. But out of a need for better mental health, he or she will persevere by thinking through the clinician's overwhelming statements. At the end, the patient may feel relieved yet exhausted by the professional terminologies.
HMW waive the patient from the work of absorbing medical information, so the patient can attend to a conversation where the doctor can provide the right advice and guidance?
In total there were 7 rounds of design critiques/reviews. I share specific and final design details here.
The screen is merely an aid.
The decision-aid was not supposed to aid a singular decision by either the patient or the doctor. It is to aid a mutual, collective, and joint one through a conversation. In my early iterations, I believed my users would want to use the tool to select the medicine of their choice as fast as possible (complete the task given). I was wrong.
As a result, the protoype evolved throughout critiques to recede into the background by providing only browsing interactions — minimum input/output. This is so the attention of the doctor and patient may be given to each other; the most important task to actually complete is for the the patient to begin to converse with the doctor and vice versa.
By restraining on-screen interactions, I intentionally reserve space for that to happen. The simple accordion interaction and short app experience redistributes attention to what’s not in the app — the patient’s conversation with the doctor; what my project team ultimately aimed to achieve.
Dr. Ian Hargraves, Designer at Mayo Clinic made this remark during our final critique:
"The accordion menu is symbolic of space-making for the most important issue, as it expands and contracts."
5+ year impact
Mayo Clinic's Knowledge and Evaluation Research Unit has since adopted my team's design vision and core user experience for development, and deployed a functioning web app to share with the general public and research community.
