Trial Outcomes & Findings for Usability Study of OnTrack Tools (NCT NCT05330234)
NCT ID: NCT05330234
Last Updated: 2024-03-18
Results Overview
In systems engineering, the system usability scale (SUS) is a simple, ten-item attitude Likert scale giving a global view of subjective assessments of usability. It was developed by John Brooke\[1\] at Digital Equipment Corporation in the UK in 1986 as a tool to be used in usability engineering of electronic office systems. The measure is scored on a 0-100 scale, a higher score means a better outcome.

Therapists
Single arm study. Participants are members of the therapy team at Imperial College Healthcare NHS Trust's stroke wards.
OnTrack Tools: The intervention is the OnTrack Tools system consisting of a graphical user interface (GUI) used to manage patients who are users of the OnTrack rehabilitation system. Participants will be asked to complete clinical and non-clinical tasks in simulation using OnTrack Tools. The themes for the scenarios of use presented in each of the three phases are summarised below:
Phase 1 - Account creation, system onboarding and general system navigation. Phase 2 - Individual patient management. Phase 3 - Content and data management.

SECONDARY outcome
Timeframe: Up to 60 days.The PSSUQ (Post-Study System Usability Questionnaire is a 16-item standardized questionnaire. It is widely used to measure users' perceived satisfaction of a website, software, system or product at the end of a study. PSSUQ follows a 7-point Likert Scale (+ NA option). 1 is "strongly agree" and 7 is "strongly disagree" Results are calculated by averaging the scores from the 7 points of the scale. The PSSUQ has one overall score and 3 sub-scales, namely system usefulness, information quality, and interface quality scored as follows: Overall: the average scores of questions 1 to 16 System Usefulness (SYSUSE): the average scores of questions 1 to 6 Information Quality (INFOQUAL): the average scores of questions 7 to 12 Interface Quality (INTERQUAL): the average scores of questions 13 to 15 The lower the scores, the better the performance and the higher the perceived satisfaction.
