The increasing use of electronic patient-reported outcome (ePRO) measures brings with it a need and an opportunity for those involved in their development, translation and use to work closely together to secure successful results.

In this case study, the collaborating parties have each contributed their expertise towards the successful migration of a patient-reported outcome (PRO) measure from its original paper-based format through to an electronic tablet-based format in more than 25 language versions.

The study focussed on the endometriosis health profile (EHP), a widely-used measure for assessing health-related quality of life in women with endometriosis, with the aim of creating an electronic version.
