Intro

Note

The shipped MVP was built under tight timelines and constraints: legacy infrastructure, legal sign-off, and shifting requirements. This case study reflects the design direction I was driving toward in parallel, exploring a more refined approach to the same problem.

The Challenge

Scrap two siloed Medical Information and Medical Affairs platforms, and build a centralized experience. One unified hub for publications, product information, disease education, congress materials, and more, designed for time-strapped healthcare professionals.

CORE DEFINITION

The clinical and scientific content pharmaceutical companies are required to provide to healthcare professionals: dosing guidance, drug interaction data, clinical trial results, therapy area education, and more.

STRATEGIC FOCUS

Focuses on strategic, high-level scientific engagement, evidence generation, and Key Opinion Leader management. For HCPs, this content doesn't just inform, but it directly shapes patient care.

Research

Research Overview

Multiples sources of evidence shaped our direction. Analytics showed an 82% bounce rate and barely 1 page per session. This was a strong signal that HCPs weren't finding what they came for.

HCP surveys and internal audits gave us the qualitative layer. Our internal audits in particular gave insights into the usability and accessibility failures behind those numbers. All sources informed where we focused our design efforts

Discovery Survey Insights

52%

of HCPs consider pharma medical websites a critical source of scientific content

92%

contact a pharma company's medical information service up to 5 times every 6 months

80%

of oncologists access prescribing and dosing info during or between patient consultations

My Role

What Did I Do?

I led UX across the platform's most high-impact features:

Search Mechanism
The platform's core use case. End-to-end ownership from concept through stakeholder alignment and delivery

Search Results Page
Content hierarchy, dynamic filtering, and tagging logic

Congresses Experience
Redesigned filter logic and layout system

Meraki Design System Integration
Collaborated directly with Pfizer's system team, proposing and introducing new components

While two designers led other areas of the platform, I owned the search system from early concept through stakeholder alignment, iteration, and delivery.

Development

From Ideation to Implementation

This was primarily a search problem. But the solution wasn't as simple as improving a search bar. Getting the right clinical content in front of the right user, compliantly and quickly, meant rethinking how queries are structured, how results are ranked and tagged, and how someone filters through thousands of assets when they have five minutes between patients.

Many, many iterations of the search experience

Project Workflow

Every decision needed sign-off from client, regulatory, and engineering teams. So that was fun. The constraints meant we had to focus on the essentials, and make some trade-offs along the way.

The Final Solution

Feature Showcase

Segmented Search

A search drawer accessible from anywhere on the site, letting users toggle between query modes: product, disease state, and beyond. Built to scale, so new query types can be added in future phases without rebuilding from scratch.

Search mechanism examples

Search Results & Filtering

Results tagged by content type, paired with a dynamic filter panel. HCPs can scan through thousands of assets by therapy area, indication, file type, and more.

Result Card Anatomy

The result card structure was carefully considered. HCPs often have limited time, so we need to ensure that each result communicates the most important information at a glance.

Congresses

A redesigned layout and filter system giving HCPs fast access to congress schedules, materials, and session content. Improved signposting and hierarchy.

Mobile Experience

HCPs aren't always at a desk. Research shows more than a quarter of HCPs spend three or more hours a day accessing clinical resources on their smartphones, and mobile drug referencing is one of the most common on-the-job use cases. The platform was fully optimized for mobile, with every core interaction thoughtfully adapted for smaller screens.

Takeaways

Impact & Next Steps

Phase I unified two legacy platforms across two markets into one cohesive system. The foundation is built to grow, with personalization, chatbot integration, and AI-assisted search on the roadmap for Phase II and III.

What we’re tracking post launch:

Bounce rate — targeting a significant reduction from the 82% baseline

Pages per session — measuring deeper engagement beyond the 1.03 avg

Search completion rate — % of queries that result in a content interaction

Time-to-content — how quickly HCPs reach what they came for

Return visit rate — a signal of platform trust and utility
