Evaluation of Usability and Acceptance of a New Autoinjector Intended for Methotrexate Subcutaneous Self-Administration in the Management of Rheumatoid Arthritis.

ABSTRACT:

Introduction

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease, for which the introduction of injectable treatments has had a major impact on quality of life directly related to the disease. The purpose of this descriptive study was to evaluate the usability of a new autoinjector, intended for methotrexate self-administration, based on the device's design and instructions for use (IFU).

Methods

This multicenter trial included three user groups: a group of patients with established RA subdivided into two groups according to their hand disability, and a group of caregivers or nurses. Each subject performed three simulated injections with a water-filled device on a foam pad. The first injection was made just after reading the IFU without further instruction
