Introduction: 

Wheelchair casters fail frequently in the field causing multiple user consequences and wheelchair breakdowns. To inform caster design improvement, there exists no validated tools that can collect caster failures. This need motivated the development of a user-reported, caster failure inspection tool (C-FIT).

 

Methods: 

To develop C-FIT, a multistep design and testing approach was used which included face validity testing, test-retest reliability testing and expert review. Reliability testing was conducted with two independent cohorts of wheelchair professionals who inspected caster failures physically and online through pictures. The tool was revised based on testing outcomes and expert feedback. For preliminary data collection and evaluating usability, C-FIT was piloted at wheelchair service centers in Scotland, Indonesia and Mexico.

 

Results: 

Caster failure items reported in the literature were screened to develop the initial list of C-FIT items. Face validity testing conducted through surveys with wheelchair experts (n = 6) provided 14 items for C-FIT inclusion. The test-retest reliability was found to be high for 10 items with physical failure inspections (n = 12). For each of these items, 75% or more participants had substantial to almost perfect agreement scores (κ = 0.6–1.0). Lower reliability scores were found with online failure inspections (n = 11). C-FIT received positive usability feedback from study participants and data collectors in the field. Pilot field data (n = 31) included comprehensive details about failures useful for manufacturers, designers and researchers to improve caster designs.

Conclusions: 

The C-FIT tool developed in this study has substantial reliability and can be used for documenting caster failures at wheelchair service centers.

Learning From Experience: Guidelines for locally sourced and cost-effective strategies for hygiene at home for people with high support needs.

This learning resource is the result of a partnership between World Vision Australia and CBM Australia that aims to improve inclusion of people with disabilities in World Vision’s Water, Hygiene and Sanitation (WASH) initiatives, including in Sri Lanka. The guidelines are based on experiences and observations from World Vision’s implementation of the Rural Integrated WASH 3 (RIWASH 3) project in Jaffna District, Northern Province, funded by the Australian Government’s Civil Society WASH Fund 2. The four year project commenced in 2014. It aimed to improve the ability of WASH actors to sustain services, increase adoption of improved hygiene practices, and increase equitable use of water and sanitation facilities of target communities within 11 Grama Niladari Divisions (GNDs) in Jaffna District.

To support disability inclusion within the project, World Vision partnered with CBM Australia. CBM Australia has focused on building capacities of partners for disability
inclusion, fostering connections with local Disabled People’s Organisations, and providing technical guidance on disability inclusion within planned activities. World Vision also partnered with the Northern Province Consortium of the Organizations for the Differently Abled (NPCODA) for disability assessment, technical support and capacity building on inclusion of people with disabilities in the project.

HYGIENE AT HOME FOR PEOPLE WITH HIGH SUPPORT NEEDS
This document is one of two developed in the Jaffna District and describes strategies that used to assist households and individuals in hygiene tasks at home. The strategies were designed to be low cost and were developed using locally available materials and skills in the Jaffna District of Sri Lanka.

NOTE: The development of this learning resource was funded by the Australian Government's Civil Society WASH Fund 2.
