The main research question was: Which usability evaluation approaches are appropriate and deployable to rapidly evaluate patient-centered eHealth inventions being iteratively developed in health care, and is it feasible to conduct an easily applicable eHealth usability evaluation as well as counter and tackle challenges that might arise during the agile eHealth usability evaluation with elderly users? The results of the triangulation study showed that the implementation of an agile, easily applicable, and useful eHealth usability evaluation with prospective users such as elderly patients proved to be feasible. Overall, 43 eHealth usability evaluation methods were identified as suitable for agile, easily applicable, and useful eHealth usability evaluations.
