Diagnosis VTE

Decision Support in the Emergency Room

Medical staff at the emergency room are faced with diagnosing and treatining a range of conditions daily, where decisions often have to be made on the fly. We helped the ER at St. Olavs Hospital leverage digital technology to aid their decision-making process.

Background

Deep Vein Thrombosis is caused by blood clots forming to block the deep veins of the leg, and in the case of Pulmonary Embolism, when these clots block the arteries of the lung. These are common conditions occuring daily at the ER, which are frequently hard to diagnose and potentially life threatening.

We have worked with St. Olavs and NTNU TTO develop an application to specifically diagnose and treat these cases, working from the first sketches to clinical testing of the app. Starting from guidelines that span hundreds of pages, we have worked towards a tool that can be used effectively in the clinical setting.

Design Process

Integrating digital tools into clinical practice is still in its infancy, and we were lucky to work with a clinic willing to take these first steps. The app has taken shape over several iterations and is currently being tested at St. Olavs. Throughout the process it has become abundantly clear how understanding the context is critical to success.

The user insights led us to structure the app for maximum flexibility and ease of use while staying within the clinical guidelines. Each stage in the patient journey is presented as an individual module in the app, used independently from each other. To provide relevance to users with varying bakcgrounds and proficiencies we worked toward the following goals:

1

Make the guidelines actionable

The existing guidelines weigh in at 840 pages. What doctors need in situ is quick, concise information.

2

Adapt to various levels of competence

We took a barebones approach to the interface to maximize efficiency for experienced users. An additional layer of background info is available on-demand.

3

Divide and conquer

A patient will typically interact with several doctors at different wards. The interface has a modular structure to allow different entry and exit points.

4

A little logic goes a long way

TUnlike static guidelines, the app allows us to filter out irrelevant information based on choices made, and thus significantly easing the cognitive load.
