This study aimed to utilize usability engineering methods in order to identify facilitators and barriers to
electronic referral system adoption by radiation oncologists at Princess Margaret Cancer Centre, and
provide recommendations for electronic referral system design. Analyses included workflow analysis of
radiation oncologists reviewing referrals, belief elicitation interviews with radiation oncologists, a
heuristic evaluation of an existing electronic referral system interface, and cognitive walkthrough of that
interface with radiation oncologists. Based on these findings, the system interface was redesigned using
mock-up software to address identified usability issues. The existing and redesigned interfaces were
compared using observational usability testing with radiation oncologists. The redesigned system
interface yielded reduced task times and enhanced user satisfaction as compared to the existing
interface. Thus, user-centred design was useful in determining facilitators and barriers to e-referral
adoption.
