Centralized Care

Human Designed Logo :)

Inspiration

One of our teammate's sister is a CRNA who often feels disconnected with her numerous patients and feels like she never has time to get caught up. She also feels like her patients who cannot get out of bed/are out of reach of a help button, but are able to use their phones need access to a way to contact their nurse for help. We created a solution.

What it does

Centralized Care lets CRNAs log into a mobile app, tap an inexpensive NFC chip beside a patient, and instantly pull up the patient’s most recent records from a secure cloud. The dashboard also lets users update notes in real time so the information stays current for everyone on the team. For patient log-in, they are able to press a call button that sends a push notification to the staffs' phone.

How we built it

We used an Expo Go front‑end, a Flask back‑end, and Ngrok for seamless tunneling, all communicating over HTTPS. The NFC tag is embedded in the patient’s chart, the phone’s NFC reader acquires a unique ID, which we match against hospital credentials stored in a json until we can implement a proper, secure database.

Challenges we ran into

Collaboration issues, we are first time hackers so being able to work together was hard. NFC capabilities on Apple are paywalled in their app developer program, so we had to work around it. Being able to use GitHub and not being able to see everyone's code at the same time. The time constraints were also giving us an issue, and being able to balance work life and code life.

Accomplishments that we're proud of

We finished our project full stack and we have a fully functioning app and system. It just needs to be upgraded in the future for proper security. We are also very proud of getting together and persevering through the hard times. Our hard work allowed us to get submitted and allowed us to be proud of our first outside-of-class project that we worked on together.

What we learned

We learned how to work more collaboratively as a team, how to manage time constraints more efficiently, and we learned how to use AI to help our workflow in an ethical way.

What's next for Centralized Care

We intend to implement proper security protocols, deploy a pilot on a real ICU, gather workflow feedback, and iterate. We also intend to incorporate role‑based dashboards and push‑automation for medication updates. Once done, we’ll open‑source the code to help hospitals worldwide jump‑start bedside data modernization. We still need to have the NFC data show up on the app rather than its dedicated server.

My name is Payton Keller, I am a second year computer engineering major. I handled backend development and integrated the code with the nfc capabilities. I hosted the tunneling for Flask to MeiliSearch that allowed the CNA to view the patient details on the website (not yet for the app). We attended workshops and we implemented these new skills into our project.

Payton Keller
I designed the Centralized Care logo and helped design the app's UI in Figma, then built the Welcome, Login and CNA Dashboard screens in React Native (Expo) and connected them with navigation. I also built the real-time patient-to-CNA call notification with Firebase and tested it on two phones.

Effie McCoy
As a UI/UX developer on Centralized Care, I started brainstorming with hand drawings and Figma. I then brought the idea to life with React Native with Expo, my priority being visual hierarchy through color and low cognitive load. This is my first time implementing any sort of application out of these softwares, but I was excited to see my work on my own device. As a general our team was nervous going into this contest knowing we have exams on Monday and had multiple hours leaving the contest to attend work. However, we were united on one cause which was our friend Wendy as mentioned in our presentation. We wanted to make sure our ideas were fully implemented to show our care and possibly push for that change in the future for all CNAS. A huge part of the process for me was brainstorming between paper designs, psychology research about mobile app designs, and discussion with Claude about possible improvements.

Jos Wirbel
I was the backend developer for the project, where I used Flask and SQLite to build a secure authorization system for our CNA user base. I also created a patient login system that gave them access to a “call” button similar to the emergency buttons that can be seen in hospitals. Finally, I implemented system that allows CNAs to access and update patient information which would then be sent back to the database.
