Usability of the "Systematic Review Support" computer system: a methodological study.

Background: (1) The "Systematic Review Support" system has a high degree of perceived usability.

Background: (2)  Its use facilitates the exclusion of duplicate references and the selection of studies.

Background: (3)  Remote and synchronous usability testing made research possible during the pandemic.

Background: (4)  Combining usability techniques made it possible to identify the necessary adjustments.

Background: (5)  The method used expanded the test's capacity in a real context of use.

to evaluate the usability of the "Systematic Review Support" computer system.

methodological study involving 21 students who evaluated the computer system in a remote and synchronous usability test. Two activities were carried out, containing 21 tasks simulating the initial steps of a review study, proposals for eliminating duplicate references, selecting studies and resolving disagreements between evaluators. At the end, participants answered the System Usability Scale questionnaire. The measures used were: completion rate with assistance (effectiveness) and time to complete the task (efficiency). The data was described in a table using the mean, standard deviation, minimum and maximum values.

in a total of 21 tasks, the participants had an assisted completion rate of 9% and an average time of 55.1 minutes (the expected time being 60 minutes). The average score provided by the System Usability Scale instrument was 82.4 (considering a score from 0 to 100), median 85; minimum value 35 and maximum 97.5.

the computer system has the effectiveness and efficiency parameters required of a computer review tool. It has a usability score of 82.4 on a scale of 0 to 100 assessed by the System Usability Scale instrument. The version presented incorporates the adjustments identified in the test in use.
