After we visited the injection molder, we then visited St. Paul Hospital, a provincial hospital located in the heart of Hanoi. Though we are targeting district hospitals – which are typically smaller and have fewer resources in terms of staff, funding, and capabilities – our interview with doctors from St. Paul was fruitful. We received two validating responses to the user experience around Otter’s interface, which we have been working throughout this past semester. (Upon asking Dr. Duong Nguyen to set the temperature to 33 degC, she pressed the buttons and then shot us a glance that said, “Is that it?”)

We also began formulating a clearer picture of medical need around Otter used in conjunction with Firefly phototherapy, our primary use-case. To better uncover this information, we created a new prop nary an hour prior to the interview: the patient flipbook. The patient flipbook allows us to quickly ask healthcare workers about which equipment they would use with a variety of patients with jaundice by highlighting four characteristics: gestational age, weight, core temperature, and jaundice severity. There is a range per characteristic (ex: mild jaundice to severely jaundice), again – allowing us to quickly cover a broad range of patients and their hypothetical journeys.

Though these are two positive takeaways from our interview, we must retain team- and project-awareness as we progress through the trip. We must remember to always validate with our target market in mind; demand at a single provincial does not equate to blanket demand at district hospitals. And, we should continuously balance streamlining our interview process against eliminating interviewing bias and answering many project questions thoroughly. Forward and onwards!
