Infection Surveillance Platform for Hospital
nurses to record patient data.

The Challenge

One in seventeen patients die due to Hospital Acquired Infections (HAIs)
Our goal was to build a platform that would help nurses capture critical patient information quickly and with minimal clicks.The fundamental premise was to help hospitals digitize the information captured by nurses on a daily basis and generate reports to detect and/or prevent HAIs. This app was designed for a tablet that was going to be used by hospitals across India.
The main goals were:
1.HAI incidence tracking and infection prevention strategy
2.Record drug bug mismatch and adverse drug reaction.

The Team

Co-Founder/CTO, UI Designer, Data Scientist

Timeline

12 Weeks, 15 Hours a week

My Role

As a UX/UI Designer I was part of a two member design team. Together we were responsible for end-to-end design and development of the digital platform. In addition, I was also responsible for conducting user testing and synthesizing results to iterate on the mock ups and clickable prototypes. I worked closely alongside the Data Scientist and the CTO.

The Solution

To facilitate effective real time surveillance, infection control and prevention of HAIs we developed a platform to recorded patient data on a daily basis by nurses. Doctors can then use the collected data to take precautionary and remedial steps to avoid HAIs.

Daily Examination

On a daily basis the nurses check every patient, file the report and the doctors review.

Drug Mismatch

Drug bug mismatch is not recorded

Manual Reports

Patient data is recorded in files and case sheets manually by the nurses

Staff Shortage

Due to shortage of staff patient infection alerts are not recorded in real time

Design

To facilitate effective real time surveillance, infection control and prevention of HAI’s we developed a platform to help nurses record patient data on a daily basis. Doctors could then use the collected data to take precautionary and remedial steps to avoid HAI’s among hospital patients. We designed for two interfaces. Both these interfaces were designed for a tablet.

Nurse Interface

This interface was designed to be used by nurses everyday to:
1. Collect old and new patient’s personal information
2. Hospital admission and discharge summary
3. Investigate infections
4. Medical Information

Doctor Interface

This interface is a dashboard for Doctors providing:

1. An overview of all the patients currently admitted
2. Information on the positive and suspected infections.
3. The doctor app also provides individual patient information (based on the data collected through the nurse app)
4. Important alerts about patients

Initial User Flow

Ideation 

It was important for the app to be easy to use and capture essential information quickly and efficiently. We also had to ensure that the interaction was familiar and learnable. There was a lot of data to be recorded and thus it was challenging to ensure that the cognitive load for the user (nurse) was minimum.
The Information Architecture (IA) hierarchy was: Create Patient profile > Daily investigations > Upload Report

Initial Sketches

Low Fidelity Wireframes

Usability Testing Insights and Iterations

Due to the aggressive deadlines I had to conduct user testing on the first draft of the high fidelity prototype. I conducted remote testing through video conferencing with 3 participants: 2 nurses and 1 IT head at different hospitals. Based on the feedback and additional data collected and synthesized, I had to redesign the interface.

Updated User Jourrney

The first step of redesign was to simplify the user flow.

Before

Iviz Old Design onboarding

1. Form is very long and overwhelming
2.Hospitals do not have patient pictures on any form.
3. Generate patient Unique Health Identification (UHID) during onboarding
4. Add drugs and dosage tab to the patient daily recording
5. Provide an option to view all patients
6. Some interactions are not perceivable
7. Make it more intuitive

After

Final Design

Learnings

This internship was my first full-time assignment as an UI/UX Designer. Since the organization was an early stage start-up, my colleague and I had to design and build the app from the ground up. Despite the steep learning curve, it was an extremely rewarding experience since I had the opportunity to successfully apply my classroom learnings to real world challenges.
The primary learnings from this project were:
• How to create designs that can capture essential information quickly and minimize cognitive load for maximum usability.
• The Importance of iteration in design. The first design is never the last one.
