Abstract [en]

Urologists, researchers and statisticians work with a centralized database in Stockholm containing more than two million prostate cancer patient records. In order to expedite the analytical process, an interactive visualization system was developed through the collaboration of Janssen and KTH. The usability of the system was measured in terms of efficiency and satisfaction. The efficiency of the system was evaluated by measuring task-time and the number of errors per task, and the satisfaction of the user was evaluated using well-established questionnaires. Through this usability evaluation, the system was evaluated as easy to use and understand.

Abstract [sv]

Urologer, forskare och statistiker arbetar med en centraliserad databas i Stockholm som består av mer än två miljoner vårdjournaler för prostata cancer patienter. För att påskynda denna process har ett interaktivt visualiserings system utvecklats genom ett samarbete mellan Janssen och KTH. Användarvänligheten av system mättes genom hur effektivt och tillfredställande det var att använda. Effektiviteten av systemet utvärderades genom att mäta hur lång tid användarna tog på sig att utföra en uppgift, samt hur många misstag de begick medan de utförde uppgiften. Tillfredsställelsen och användarvänligheten av systemet utvärderades genom väl etablerade frågeformulär. Systemet evaluerades till lätt att använda och förstå.
