Proteus Discover

Proteus Digital Health is a silicon valley technology company looking to transform healthcare through an entirely new category of pharmaceuticals called Digital Medicines. Over ten years of development has seen the company accumulate hundreds of patents, conduct multiple clinical trials and win FDA approval for it’s completely unique product — a tiny ingestible sensor that, when combined with medication, can be tracked by a wearable patch. This technology allows the company to develop apps that can be used by patients to see whether they are taking their medication correctly.

Proteus Discover uses this technology to help patients with type 2 diabetes, high blood pressure or hepatitis C better manage their daily medication taking — conditions that when not treated properly can lead to serious complications.

Case study: Introducing Proteus Discover


The technology behind Proteus Discover is so novel that doctors and nurses struggled to explain to patients what it is, how it works, and what value it brings. Lengthy set up appointments were needed to answer patient questions and get them started on the programme. To relieve this burden, a website was create to:

  • show the value of the product and encourage patients to register

  • reassure patients that it’s safe and secure

  • set the correct mental model about how it works in order to avoid confusion in later use


As the design lead on this project I managed the creation of this site from conception through to final delivery. This involved:

  • working with the user research team to develop and test value propositions and messaging

  • working with product and service design teams to plan how the sites sits within the patient journey

  • working with a copywriter to develop content

  • working with film makers and animators to create video content

  • developing how the brand is expressed online

  • creating design iterations and working with the user research team to evaluate solutions

  • creating specs, and working with interaction designers and developers to realise the build of the site


The launch of the website allowed clinical sites to do patient outreach over phone or email. Therefore reaching a larger number of patients and increasing enrolment. By allowing patients to register at home in their own time, the site also reduces the number of clinic visits for patients.

Case study: Patient set up


Proteus Discover was initially launched at low volumes with a handful of clinical sites. Individual parts were shipped directly to clinics, where nurses helped patients get set up. In order to make the product commercially viable at scale, we needed a kit that could be supplied through a mail order pharmacy, that patients could use to get set up on their own.

As the product is used across a number of different use cases, we could not create one complete package that would work for everyone. Patients either download an app to their phone, or are loaned an iPad. They will have different combinations of medications. They may need different quantities of disposable adhesive strips depending duration of use. We therefore needed to create a packaging solution that would provide an easy to use starter kit, that could be shipped with the supplies needed for ongoing use.


As the design lead on this project, my role was to ensure that we could get the best possible patient experience within a complicated product launch. In particular, I was responsible for:

  • working closely with the product management team to gather requirements from multiple stakeholders and driving alignment on priorities

  • translating requirements into a clear design brief

  • collaborating with product designers Tone Design to develop concepts for the physical form of the kit

  • developing effective quick start guides and working with interaction designers to ensure a smooth transition from the physical to digital experience

  • developing how the brand identity is applied to packaging

  • working closely with the user research team to conduct usability studies, observing every session and taking part in daily debriefings

  • finalising design outcomes, creating specs, and working with packaging supplier to deliver the final product


Due to regulatory constrains we had to keep parts of the medical device in their primary packaging and ‘over pack’ these with the starter kit. This meant we had to ensure that patients could easily find the parts that they needed in the correct order, whilst being presented with boxes within boxes. 

Having previously tested numerous configurations of kits and quick start guides, our final usability study showed the highest level of success in set up from any user testing to date. As a result we were confident that we could launch with a design solution that would help get patients set up without confusion. 

We established that paper instructions should focus on getting patients into the app experience and over come basic problems which were surfaced in user testing, such as trouble finding the on/off button on the iPad, and confusion about where to look for the app.

Further work: Brand development

In developing the brand, we not only thought about values, tone of voice and visual identity, but also inclusive design principles, such as ensuring our typography, colour pallet and graphic devices were legible enough to meet the accessibility standards demanded by a medical device.
