Summary
Background: The Website Developmental Model for the Healthcare Consumer (WDMHC) is an extensive
and successfully evaluated framework that incorporates user-centered design principles.
However, due to its extensiveness its application is limited. In the current study
we apply a subset of the WDMHC framework in a case study concerning the development
and evaluation of a website aimed at childhood cancer survivors (CCS).
Objective: To assess whether the implementation of a limited subset of the WDMHC-framework is
sufficient to deliver a high-quality website with few usability problems, aimed at
a specific patient population.
Methods: The website was developed using a six-step approach divided into three phases derived
from the WDMHC: 1) information needs analysis, mock-up creation and focus group discussion;
2) website prototype development; and 3) heuristic evaluation (HE) and think aloud
analysis (TA). The HE was performed by three double experts (knowledgeable both in
usability engineering and childhood cancer survivorship), who assessed the site using
the Nielsen heuristics. Eight end-users were invited to complete three scenarios covering
all functionality of the website by TA.
Results: The HE and TA were performed concurrently on the website prototype. The HE
resulted in 29 unique usability issues; the end-users performing the TA encountered
eleven unique problems. Four issues specifically revealed by HE concerned cosmetic
design flaws, whereas two problems revealed by TA were related to website content.
Conclusion: Based on the subset of the WDMHC framework we were able to deliver a website that
closely matched the expectancy of the end-users and resulted in relatively few usability
problems during end-user testing. With the successful application of this subset of
the WDMHC, we provide developers with a clear and easily applicable framework for
the development of healthcare web-sites with high usability aimed at specific medical
populations.
