Design an App to help Peritoneal Dialysis (PD) patients have better control of the dialysis process via data recording and trend analysis.


Over 1,000,000 kidney failure patients are found to be depressed. UpperMed’s solution, PD care, will help PD patients to solve their daily challenge. In order to better track their treatment journey, PD care APP can record body liquid balance, blood pressure and body weight. Patients with a smart phone can use our APP to download the data and manage their health with the member of the family and physicians.Peritoneal dialysis(PD) patients Uppermed created a portable device for Peritoneal Dialysis patients to self-dialysis everywhere and anytime

Problem statement


Traditional treatment 

PD is driven by gravity, by hanging 2kg dialysis bag at a higher place. Being away from home, it is very challenging to find a friendly place which is clean to do dialysis.

Manually writing down the body data, wasting time and annoying 

PD patients need to record their inflow volume and outflow volume manually by themselves on paper 4 times a day. It is time wasting and hard to track the data.

Portable PD care, users can do treatment anywhere

APP to record and track body data and treatment progress

Business model

Charge customers directly with subscription model (charge per month). Approach customers through doctor.


Understand PD patients' pain point and doctor's need

Interviewing over 20 Peritoneal Dialysis patients from age 35 to 60, we discovered two main problems and developed a persona below. Most of them already started dialysis from 10 years ago. They wish to have a life like normal people to keep working and traveling.

Peter, 40, a manager in a semi-conductor company

Continuous Ambulatory Peritoneal Dialysis treatment for 5 years. I exchange body fluids in the office bathroom, in the car or a meeting room without people.


I feel annoyed that every time I exchange the body fluid I need to record the time and the fluid volume manually. And if I'm too busyI might ignore the abnormal value I had. 


I wish someone could help me check my abnormal value so that I don't need to calculate by myself, and also remind me to make a return visit to the hospital in my busy life.

The purpose of this product

  • Patients do self treatment at home 

  • Easy communication between doctors and patients

  • Help doctors tracking patients progress easily

Clear way to show important information after syncing up data from self-treatment machine

Abnormal value reminding:
explain the reason and contact way to the doctor or nu

Tracking the patients' improvement progress

Remind the patients returning checking

Learn from other competitors

  • Graph to show the specific time, and can check the details.

  • Show the most important value for the data: the average, the total (depends on the item) 

  • Patients can remark the in the data 


Ideation for dashboard

Patients need to measure 2 times for pressure, two times for weight and 4 times for CAPD.

With the tab bar, it's easy to see where they are now and switch to different item's trend.


Change to different periods easily to view other trends.


After clicking note icon, there is a modal popup showing the note details on the same page. It makes it easy to view the note taken on that day and it's useful for patients to communicate with the doctors.

Clicking "check my appointment" will lead to my appointment detail page, where patients can edit the note.

UI and Illustration ideation

This takes reference from This lively and flexible style really suits uppermed. We want to promote a relaxing and healthy lifestyle, so we apply blue and green colours, and plants to be the main illustration.

Flower blooming represents the hope and life.

Illustration icon

Icons with colour spot makes it easy to recognise, and has a lively style to it too.

Plant illustration

Adding texture to the grass makes it into a rich looking and multilevel design.

Iteration after usability test

A total tests were performed on 10 patients. In addition to operational problems, we also found issues on operational problems, we also found issues on patients’ concerns. For example, the blood tests that patients need to have every three months often require a lot of paper records. Some patients also expressed a desire to be able to understand the normal range of each body data without having to go through a thick manual. Their requests give us a better understanding of the needs of the peritoneal dialysis population.


Improvement from aiming easy to communicate with doctor and nurse, easy to navigate, easy for non-tech users 

1.Today for the title of this page is not that flexible in stead of using general title like My dashboard.
2.Too many icons for non tech people are not easy to use at the first time.
3.Too many action on the main page.
4.Interaction is not that user- friendly.
5.Too many information on one page, users are hard to digest and find the useful information.

When the user is already on the detailed page, they usually cannot think to go back to the dashboard to add data.

This project required cooperating with a startup doing a hardware and software product and I'm responsible for the App design. The challenging part is verifying the Bluetooth connection with the hardware device and the App because of the slow implementation of the device. Therefore we tried to focus on the App and get user feedback via interviews and usability tests with patients. This App will also help this startup to get funding by showing good test results from the patients and doctors. The most interesting part is to transform the complex paper note-taking method into a digital one with simple input and output communication. 

Results and next step

10/10 of patients think the concept is successful and help their life easier while doing dialysis treatment.
7/10 of patients think it's good to quickly see their today results on dashboard .
5/5   of doctor and nurses provide
 positive feedback  will help them remind patients to return visit the hospital. It reduces labor from hopistal.

In the future, there might be a version for Hemodialysis patients and a specific online market function for Kidney disease patients to purchase their medicine and supplies, as well as a function to add partners so they will feel less lonely doing treatments and allow data to be tracked by family.

Lessons learned

It is a project through which I understand more about Peritoneal Dialysis patients. Their life is so inconvenient because of doing Continuous Ambulatory Peritoneal Dialysis. They need to exchange body fluid four times a day. I developed empathy to put myself in their shoes. This App is to help them reduce the pain for an inconvenience in daily life such as recording the body condition on paper. Therefore, they can live happily and like normal people with Uppermed.

I joined the project starting with the interview, usability test with patients. I cooperated with a CEO in a tech start-up, to think from a business and product perspective. I enjoyed this project by transforming the user's pain point into an innovative and workable solution that is satisfying for the users.
