Can a previously co-designed device be used by others? A service evaluation of the use of the Sativex spray holder for individuals with multiple sclerosis.

PURPOSE

Co-design has previously been used to design custom assistive devices, involving the end user in the process to ensure the device meets their needs. From devices previously created, designs could be re-used and modified to meet variations in the needs of other individuals with similar clinical needs. This service evaluation explored the re-usability of a holder for helping administer the spray medication Sativex, for individuals with multiple sclerosis.

METHODS

This evaluation was conducted in a UK based Rehabilitation Engineering NHS department. Five individuals who were currently prescribed Sativex trialled the device and provided feedback to further customise the device. Questionnaires evaluated the satisfaction and impact of the devices provided. The resources to provide the devices were calculated.

RESULTS

Three of the five individuals who trialled the Sativex spray holder were using long term. Modifications to the shape of the holder were made due to differences in hand strength and dexterity from the initial user. Results indicated high satisfaction with the device and service provided, with improvements in the individuals' competence, adaptability and self-esteem. The mean cost of providing and modifying the device was £78.62.

CONCLUSIONS

The previously co-designed Sativex spray holder was used by other individuals, demonstrating how a co-design framework can be used to identify user needs and modifications to previous designs and then implement design changes. The wider use of the device helped off-set the initial costs associated with co-designing devices. Further work is required to explore how other devices could be modified to meet individual needs.
