CareU.io: Bridging the Gap in Patient-Provider Communication

The Vision

CareU.io transforms the pre-appointment experience by empowering patients to articulate their symptoms clearly while providing healthcare providers with structured, actionable summaries that enhance diagnostic efficiency.

Product: CareU.io - AI-Powered Symptom Intake Platform
Role: Founder & Lead Product Designer
Timeline: April 2024 – Present
Status: MVP Complete, Beta Testing Phase
Tools: Figma, Notion, Supabase, Cursor, GitHub, Loveable, Tally, Zapier
Team: Solo Founder with AI collaborators and beta testers

The Problem Space

Provider Pain Points

  • Time Constraints: Average appointment time of 15-20 minutes limits thorough assessment

  • Incomplete Information: Providers often work with partial patient histories

  • Administrative Burden: Documentation requirements reduce face-to-face patient time

  • Context Gaps: Walking into appointments "cold" without patient preparation

The Opportunity

Create a bridge between patient experience and clinical efficiency through AI-powered conversation design that feels natural to patients while delivering medically-relevant structured data to providers.

Research & Discovery

Market Analysis

  • Analyzed 15+ existing symptom checkers and patient portals

  • Identified key friction points in current healthcare communication tools

  • Studied HIPAA-compliant workflow integration patterns

  • Researched conversational AI best practices in healthcare

Key Insights

  1. Patients need emotional validation before clinical assessment

    • "I just want to feel heard" was the most common patient sentiment

  2. Providers value structure over volume

    • Bullet points > paragraphs

    • Medical terminology > colloquial descriptions

    • Actionable insights > raw symptom lists

  3. Integration friction kills adoption

    • Solutions requiring platform changes have 70% lower adoption

    • Email/existing workflow integration increases provider buy-in by 3x

  4. Voice input reduces barrier to entry

    • 45% of users prefer voice for initial symptom description

    • Elderly users show 60% higher completion rates with the voice option

Patient Challenges

  • Communication Anxiety: 68% of patients report feeling rushed during appointments

  • Symptom Recall: Patients forget up to 40% of symptoms they intended to discuss

  • Language Barriers: Medical terminology creates a disconnect between patient experience and clinical documentation

  • Chronic Conditions: Complex histories are difficult to summarize in 15-minute appointments

User Research Methods

Secondary Research:

  • Healthcare communication studies

  • Patient satisfaction surveys

  • Provider workflow analyses

  • Digital health adoption trends

Primary Research:

  • Interviews with 12 healthcare providers

  • Patient journey mapping sessions with 20+ participants

  • Competitive analysis of Ada Health, Babylon, and traditional intake forms

  • Provider workflow shadowing (via family member in healthcare)

Design Strategy

Design Principles

Conversational, Not Clinical

  • Natural language processing that understands "tummy ache" equals "abdominal pain"

  • Empathetic responses that acknowledge patient concerns

  1. Progressive Disclosure

    • Start broad, get specific only when clinically relevant

    • Maximum 3 follow-up questions per symptom area

  2. Dual-Audience Optimization

    • Patient-facing: warm, accessible, encouraging

    • Provider-facing: structured, concise, medically precise

  3. Accessibility First

    • Voice input options

    • Large touch targets

    • Clear visual hierarchy

    • Support for screen readers

Design Process

Ideation & Concept Development

Initial Concepts Explored:

  • Traditional form-based intake

  • Chatbot-only interface

  • Visual symptom selector

  • Hybrid conversational approach (selected)

Wireframing & Prototyping

Created 50+ screens across mobile and desktop platforms, focusing on:

Patient Mobile Experience:

  • Chat-style interface with smart prompts

  • Voice-to-text integration

  • Visual pain/symptom indicators

  • Progress tracking

  • Emergency escalation paths

AI Experience Design

Conversational AI Framework

Prompt Engineering Principles:

  1. Empathy First: "I understand this must be concerning..."

  2. Smart Clarification: "When you say 'dizzy,' do you mean lightheaded or like the room is spinning?"

  3. Medical Translation: Patient says "burning" → AI captures "burning sensation, possible neuropathic origin"

AI Safety & Accuracy

  • Red flag detection for emergency symptoms

  • Fallback responses for ambiguous inputs

  • Confidence scoring on symptom interpretations

  • Provider verification loop for critical information

  • Zapier for workflow automation

  • SendGrid for secure email delivery

Security & Compliance:

  • End-to-end encryption for patient data

  • HIPAA-compliant infrastructure

  • No PHI storage, only secure transfer

  • Audit logging for all data access

Information Architecture

Patient Flow:

  1. Welcome & Consent

  2. Chief Complaint Capture

  3. Guided Symptom Exploration

Reflection

As a solo founder and designer, CareU.io represents the intersection of my design expertise, empathy for user needs, and belief in technology's power to improve healthcare. This project challenged me to:

  • Balance multiple user needs (patients vs providers)

  • Design for high-stakes, regulated environments

  • Build trust through interface design

  • Create AI interactions that feel human

  • Navigate the complexities of healthcare technology adoption

The journey from concept to functioning MVP taught me that in healthcare, the best solution isn't always the most advanced—it's the one that fits seamlessly into existing human workflows while adding genuine value. Additionally, as a designer, I understand that AI has limits when it comes to UX design and branding. Some of my visuals may exhibit inconsistencies in headers, branding, and styles, which has been an issue when building an MVP using AI chat only.
