Protocol for a rapid review to inform concept elicitation and measure selection for an electronic patient-reported outcome (ePRO) system for patients with haematological malignancies receiving CAR-T cellular therapies

This protocol describes a rapid review that aims to examine the existing literature reporting the use of patient-reported outcomes (PROs) and patient-reported outcome measures (PROMs) associated with CAR-T cell therapies. The review findings will inform measure selection for a new electronic PRO (ePRO) system for use with patients with haematological malignancies who receive CAR-T cell therapies.
