A Cognitive User Centered Redesign of a Radiotherapy Chart

Abstract

We describe the human factors analysis and redesign of the radiotherapy paper chart used at the radiotherapy unit of Rambam Medical Center. The chart is a paper form used by multiple team members. It is the main record of relevant information and treatment orders. It also serves as the major follow up and quality control tool. As such, the chart is a major communication, reference and decision making aid, which has a direct influence on the treatment quality and patients safety and health. Analysis of the existing chart revealed multiple content and format design problems, which raise the probability of errors. The new design of the chart attempts to resolve these problems. At present, it has been adopted by the unit and hospital and is in the process of being produced and introduced to the unit.
