At a Glance

Stryker approached us to redesign the Consolidated Operating Room Equipment (CORE) console which houses controls for drilling and irrigation during surgery.

 

Through an iterative design and research process, we created a simple and user-friendly design that increased the confidence and accessibility to information. It allowed circulating nurses and sales reps that control the system, as well as surgeons who need to see the information from a distance, in the stressful operating room environment, to access the information when it matters.

How we did it

Our role was to re-design the CORE experience while maintaining its current feature set, following brand guidelines, and keeping in mind the next generation of CORE systems that would follow to ensure a seamless transition for users. This all needed to happen on a 7-inch screen that lives within operating rooms around the world. We needed to improve the system by delivering tailored experiences to each user: the surgeon, sales rep and circulating nurse. 

How We Did It

Curvy line

To re-design this product we followed an iterative research and design process. We started with stakeholder interviews to familiarize ourselves with the current product and identify the following design philosophy to guide the wireframes we created. 

 

Scalable and Consistent Framework

Create a consistent visual language and workflow to increase predictability and approachability inside the operating room while creating an intuitive menu structure to simplify common tasks. Maintain a future-forward perspective to allow the interface to accommodate additional features to come.

 

Ease of Learning for Each Role

Provide each user type with the right information at the right time, allowing for more complexity when it is needed to allow for users to master each feature.

 

Important Features to the Forefront

Stay one step ahead of the user by providing easily accessible actions, options and alerts when the situation and user group benefits from it.

 

Error Avoidance and Recovery

Plan for how errors occur and provide the user with paths to avoid and recover whenever possible, providing an extra layer of comfort when exploring the system.

How to image

Our team observed surgeries to kick start an initial discovery research phase focused on understanding who used the system and how they interacted with it, as well as what the system needed to accomplish for each role. We then entered rounds of usability testing with sales reps and circulating nurses to refine our designs.

 

Since usability testing could not take place during live surgery, we had to get creative in order to test our designs. During the first round of testing, design concepts on an iPad were placed inside of the console to mirror its real use inside the OR. For the second round of testing, we converted our research lab in San Jose, CA to an operating room to recreate the experience circulating nurses would have during surgery. Because of this setting, we were able to utilize our higher fidelity prototype with updated designs. Both approaches allowed the research participants to get in the right headspace and feel closer to the real environment in which they would use the product in yielding more organic and honest feedback. 

The
Outcomes

The final design solution reduced the likelihood of errors in the high stakes surgical environment. It was simple and consistent making it easy for surgeons, nurses, and sales reps to use and allow each role to complete goals quickly and efficiently; all while the patient is on the operating table. All designs and accompanying specification documents were delivered to Stryker’s developers to guide them to bring the system to life consistently with the findings from research.
