Evaluation of a flowchart-based EHR query system: a case study of RetroGuide
Huser, Vojtech et al, Journal of Biomedical Informatics, Article in Press, Accepted Manuscript
Provision of query systems which are intuitive for non-experts has been recognized as an important informatics challenge. We developed a prototype of a flowchart-based analytical framework called RetroGuide that enables non-experts to formulate query tasks using a step-based, patient-centered paradigm inspired by workflow technology. We present results of the evaluation of RetroGuide in comparison to Structured Query Language (SQL) in laboratory settings using a mixed method design.
