My Role

UX Researcher and Designer

Timeline

Spring 2024 Semester: Jan 2024 to May 2024

Overview

Developed a Clinical Decision Support System to enhance personalized nutrition guidance for dietitians. This project integrates behavior change theories with UX research to support nutritionists in tailoring recommendations to individual health needs, thereby improving the accuracy and effectiveness of care.

Concept Statement

Bridge UX design and clinical research to empower dietitians with a user-centered tool that adapts to unique patient diagnoses and needs.

Research Approach

Conducted mixed-methods UX research, including interviews with dietitians and clinical researchers, to understand the decision-making processes in nutrition education. Insights from these studies informed the system’s design, emphasizing a personalized approach to nutrition education.

Why something like this is necessary?

In the rapidly evolving field of nutrition, staying current with the latest research and guidelines is a challenge. Clinical Decision Support Systems (CDSS) offer essential benefits for nutritionists and their clients.

Accurate Decision-Making

CDSS provides evidence-based recommendations, reducing human error and ensuring precise nutritional advice based on the latest research.

Efficient Data Management

CDSS organizes and interprets patient data efficiently, saving time and allowing nutritionists to focus more on patient care.

Personalized Nutrition Plans

CDSS tailors recommendations to individual needs, improving adherence and health outcomes through customized dietary plans.

Up-to-Date Information

CDSS continuously updates with the latest studies and guidelines, ensuring nutritionists always have access to current data.

Improved Patient Outcomes

By using CDSS, nutritionists can provide more effective care, leading to better health outcomes in managing diseases, supporting weight loss, or enhancing performance.

Collaborative Care

CDSS facilitates better communication among healthcare providers, ensuring dietary recommendations are integrated with overall treatment plans.

In summary, a CDSS is vital for modern nutritionists, enhancing care quality, improving patient outcomes, and advancing the nutrition field.

Problem Statementâť“

Nutritionists often struggle to provide personalized dietary guidance due to the complexity of individual health conditions and behavioral factors. Existing tools lack the sophistication to integrate these elements effectively, resulting in suboptimal outcomes.

Our solution: a CDSS that empowers nutritionists to deliver precise, personalized recommendations by incorporating behavior change theories and individual diagnoses.

The Big Opportunities

Opportunity from a Research Standpoint

Implementing a Clinical Decision Support System (CDSS) for nutritionists offers significant research opportunities. It allows for the collection and analysis of vast amounts of data on dietary habits, health outcomes, and patient compliance. This data can be used to identify trends, develop new nutritional guidelines, and enhance evidence-based practices. Furthermore, it provides a platform for conducting longitudinal studies to understand the long-term impacts of personalized nutrition plans.

Opportunity from a UX Deep Dive Standpoint

A CDSS provides a unique opportunity to delve into the user experience (UX) of nutritionists and their clients. By focusing on UX design, we can create an intuitive, user-friendly interface that simplifies data entry, improves user satisfaction, and enhances engagement. A deep dive into UX also helps in identifying pain points and areas for improvement, ensuring that the system meets the needs of its users effectively. This focus on UX can lead to higher adoption rates and better overall user experience.

Opportunity from a Business Standpoint

From a business perspective, developing and implementing a CDSS for nutritionists presents a lucrative opportunity. It opens up new revenue streams through subscription models, partnerships with healthcare providers, and data analytics services. Additionally, it can position a company as a leader in the health tech industry, attracting investment and fostering innovation. The system's ability to improve patient outcomes and streamline workflows can also lead to cost savings for healthcare providers, further driving its market adoption.

In conclusion, the development and implementation of a CDSS for nutritionists offer vast opportunities from research, UX, and business perspectives, making it a highly valuable endeavor.

Objectives

There are 4 types of objectives we planned around:

User Objectives

To understand the pain points of nutritionists with varying levels of experience, and give them an easy to adopt solution which can help them deliver nutrition education to their patients in a more efficient manner, tailored to their behavior patterns.

Business Objectives

Since this is a non-funded research initiative, the business objective is to deliver a prototype that would attract funding/grants to this project to take it further, and eventually deploy it to the healthcare technology market.

Time Bound Goals

Since this project is part of an entire research lab at the Dell Medical School at the University of Texas at Austin, my personal time bound goal was to deliver initial UX research insights in collaboration with the clinical research team. My responsibility was also to deliver the first high fidelity prototype by May 2024. The long term goal is to have a working, developed prototype with the core functionalities by Fall of 2025

Metrics of Success

Successful adoption by both new and experienced dieticians, high SUS (System Usability Scale Scores), and in the longer term, higher patient satisfaction.

Research Methods

Literature Review:

Analyzing existing studies on behavior change theories and their application in nutritional counseling.

Surveys and Interviews:

Engaging with nutritionists to understand their pain points and requirements.

Competitive Analysis:

Evaluating current CDSS tools to identify gaps and opportunities for improvement.

Insights

User Insights:

Through in-depth interviews and surveys with dietitians and patients, we gained valuable insights into their needs and pain points. Dietitians emphasized the need for a streamlined interface that integrates seamlessly with existing workflows and allows quick access to personalized educational materials. Patients expressed a desire for clear, easy-to-understand dietary recommendations that are tailored to their individual health goals and preferences. These insights shaped our approach, ensuring that our CDSS interface is both user-friendly and highly personalized.

Market Insights:

Our market research revealed a growing demand for digital tools that support personalized nutrition education. The healthcare industry is increasingly focusing on individualized treatment plans, driven by advances in data analytics and behavior change theory. Competitor analysis highlighted the gap between current offerings and the specific needs of dietitians and patients, validating the unique value proposition of our CDSS. This market trend underscores the potential impact and adoption of our solution in clinical settings.

Testing Assumptions

Impact on Project:

To validate our design assumptions, we conducted several rounds of user testing with dietitians and patients. Initial prototypes were evaluated for usability, functionality, and effectiveness in delivering personalized nutrition education. Feedback indicated a need for more intuitive navigation and enhanced integration with electronic health records. By iterating on these prototypes and incorporating user feedback, we significantly improved the user experience, ensuring our CDSS meets the practical needs of its users.
