The Problem

The Solution

We achieved

Today, this project is live and helping the Korea University Hospital build an extensive user database and treat them better. On average, around 350 patients use this platform on a daily basis in the hospital.

Leading the design process

Uncovering problems through stakeholder interviews

During patient research at the medical center, we identified inefficiencies in the hospital system, prompting our project initiation. Through interviews and observational research with doctors, nurses, and patients, we comprehensively understood existing problems.

Our solution benefits all stakeholders: doctors can optimize patient time for precise diagnosis and treatment, nurses can streamline communication and focus on essential care tasks, and patients can utilize waiting time effectively, receiving accurate diagnoses promptly.

Conceptualization

Through visualization of the hospital service process, we identified areas for improvement in efficiency and highlighted challenges faced by stakeholders. Specifically, we pinpointed two key pain points: the documentation and waiting time experienced by newly arrived patients, and the collation of patient data for medical research purposes.

Wireframing & Usability Testing

Created low-fi wireframes and developed to mid-fi to conduct user testing. Usability testing assesses 3 main aspects: UX writing, accessibility, and overall usability. I conducted unmoderated user testing to earn rapid feedback and efficient data collection. It contained internal sessions with a medical team and external sessions with three regular patients who visit the hospital more than 3 times a month.

UX Writing Audit: Enhancing Patient-Friendliness

Collaborating with a medical team, I reviewed the clarity, accessibility, and empathy of the UX writing to ensure that it effectively communicates information to users with diverse backgrounds and levels of health literacy. Specifically, we assessed whether the terminology used in the app is user-friendly and accessible to patients, avoiding jargon and technical language whenever possible in favor of plain language that is easy to understand.

Accessibility Enhancement

Mainly focusing on UI accessibility assessment, I ensured every component met the color contrast ratio and touched target sizes of interactive components to be larger than 44x44px

Discoverability improvement

Users encountered difficulties navigating back and forth within the questionnaires. To address this, I relocated the back button beside the next button for smoother navigation. Additionally, users tended to overlook the note feature located at the bottom section for adding extra information. I integrated this option into the main section for easier access and utilization.
