Neopenda (Vitals Monitoring Dashboard) - UX Case Study

Mid-fidelity Tablet App Prototype (UX)


UX Designer/Lead Prototyper: In addition to conducting interviews, concept tests, and usability tests with my team, I prototyped the most critical feature of our solution in Axure over two days, delegated the converged prototype design to team members, and refined the final prototype after testing.

Facilitator: I led and facilitated group activities for synthesis, ideation, information architecture, and goal setting for internal group and external client meetings.

Tech Translator: I was familiar with the tech stack used by Neopenda’s dev team to create their web app prototype, including Node.js and React, and took the time to translate descriptions of technology to the design team.

Neopenda tasked our team to work on a 4-in-1 vitals monitoring system for neonates in low-resource environments.

We entered the world of Ugandan neonatal nurses.

Africa has the highest fertility rate in the world. However, the lack of infrastructure, skilled people, and functioning equipment results in bleak outcomes for newborns. Many newborns are premature and have problems at birth, which are exacerbated by the lack of monitoring equipment, and the disproportionate newborn-to-nurse ratio in NICUs. Our client, Neopenda, passed along several statistics comparing NICUs in Uganda to the United States. In low-resource environments, nurses have to manually check newborn vitals one at a time in NICUs with a 20:1 newborn-to-nurse ratio. In comparison, NICUs in the United States have a 1:1 newborn-to-nurse ratio and high-end equipment to monitor sick newborns.

Neopenda’s goal is to bring vital signs monitoring, a basic tenet of clinical care, to Uganda and other low-resource environments in an affordable device.

Our client
Sona (CEO) and Tess (CTO) met at Columbia University completing their Master’s in Biomedical Engineering. They conducted interviews and design feedback sessions with over 150 nurses and doctors at 43 health facilities in every region of Uganda.

Our audience
We focused on nurses and physicians (neonatologists, pediatricians, obstetricians) in Ugandan health facilities who work with newborns, with a focus on ill newborns in neonatal special care units (NICUs). In Uganda, neonatal nurses tend to be female, 20-50 years old, speak English, and educated in nursing, but low-income and may have limited familiarity with tablet/app technology.

It was exciting to work on a project that impacts the lives of neonates in low-resource environments. In addition to impacting the lives of Ugandan babies, I had the unique opportunity to develop a remote test plan to test our solution in Uganda, speak with Ugandan nurses and understand their unique perspectives, and face the challenge of designing an effective display of quantitative data. In addition to bringing a web development background and familiarity with the tech stack Neopenda’s development team used to build the initial prototype, I also brought my perspective of living in a developing country (Indonesia), seeing the chaos and disorganization of medical wards in countries outside the United States, as well as my experience speaking to non-native English speakers.
