The Betsy Lehman Center
Designing an interface for providers to access patient safety tools
🚩 Problem
Patient safety errors occur frequently in medical clinics and impact patient health outcomes.
🥅 Goal
Collaborate with BLC to understand why these safety errors occur even though healthcare providers (HCPs) have tools to prevent them and deliver a targeted solution.
💡 Outcome
Design a website based in behavioral change theory to connect HCPs to patient safety resources.
Overview
The Betsy Lehman Center for Patient Safety (BLC), a Massachusetts state agency, needed to understand why patient safety errors were occurring more frequently in outpatient clinics than inpatient clinics, despite the availability of safety tools for healthcare providers.
Over the course of four months, I worked with the Deputy Director of the BLC to create a website that would give providers access to existing safety tools. I conducted research using literature reviews & in-depth interviews (IDIs), synthesized data with affinity mapping, and designed high-fidelity wireframes based in research insights.
📝 Process
Understand the Background
I conducted a literature review to understand why patient safety errors occur, which errors occur most commonly, and what tools exist to tackle them.
I learned the causes of safety errors occurring in clinics and bucketed them into four categories of an affinity diagram.
My research revealed there are a lot of safety tools available to prevent safety errors, but they aren’t utilized by providers. I conducted primary research to uncover the behavioral causes that prevented HCPs from employing these tools.
Conduct Primary Research
I conducted in-depth interviews (IDIs) to understand why providers aren’t using tools available to them. I conducted six IDIs with providers among five clinics. I used IDIs to uncover cause of provider behavior.
I created a research plan based in the Technology Acceptance Model (TAM), a behavioral change theory that would help providers adopt a new behavior.
I developed three research stimuli to conduct interviews: a discussion guide and two sample patient safety tools.
I recruited subjects by leveraging the existing BLC network and researching nearby clinics in the Boston area.
🧠 Synthesis
Analyze the Data
I used qualitative coding to translate findings into actionable insights. Analysis revealed two overarching issues preventing providers from using existing tools:
#1 Lack of Time - HCPs want to improve patient safety, but lack time during their workday to learn about and/or implement new safety protocols
#2 Lack of Safety Culture - Most offices lack adequate patient safety culture that results in frequent medical error
💥 Impact
Research Informed Design
The team was able to build a one-stop-shop website for targeted, peer-reviewed patient safety tools. We directly targeting our two key insights from research:
#2 Lack of Safety Culture
Created site sub-pages that directly addressed patient safety issues that were highlighted by stakeholders in interviews
Developed a specific sub-section for the website with tools directly related to improving patient safety culture
#1 Lack of Time
Created a simple website format that was quick to navigate
Populated the website with tools that were generalizable, easy-to-use, and scalable
Highlighted a “Tool of the Month” subpage to deliver BLC-reviewed tools directly to providers
⏪ What would I do differently?
Next Steps
Immediate
Complete usability tests (unstructured, moderated card sorting) on wireframes to determine if the website architecture is end-user intuitive
Complete heuristic evaluation of patient safety tools to determine if they are useful and appropriately labeled in the easy-medium-hard scale
Long-term
Conduct a longitudinal/diary study to observe whether a behavioral change has occurred after the availability of this website
Survey providers to assess if there has been a decrease in safety errors in clinics
Identify unintended outcomes and update the site to address these issues
What would I change?
With More Time & Budget
Increase number of interviews with HCPs to find more patterns in insights
Observe providers in clinics over a longer course of time to understand the key intervention points necessary to change behavior
Complete usability testing on low fidelity prototypes with HCPs to highlight issues with the wireframes early on
