A case study of the assistive technology network in Sierra Leone before and after a targeted systems-level investment

Background Many people with disabilities in low-income settings, such as Sierra Leone, do not have access to the assistive technology (AT) they need, yet research to measure and address this issue remains limited. This paper presents a case study of the Assistive Technology 2030 (AT2030) funded Country Investment project in Sierra Leone. The research explored the nature and strength of the AT stakeholder network in Sierra Leone over the course of one year, presenting a snapshot of the network before and after a targeted systems level investment. Methods Mixed-method surveys were distributed via the Qualtrics software twice, in December 2021 and September 2022 to n=20 and n=16 participants (respectively). Qualitative data was analyzed thematically, while quantitative data was analyzed with the NodeXL software and MS Excel to generate descriptive statistics, visualizations, and specific metrics related to indegree, betweenness and closeness centrality of organizations grouped by type. Results Findings suggest the one-year intervention did stimulate change within the AT network in Sierra Leone, increasing the number of connections within the AT network and strengthening existing relationships within the network. Findings are also consistent with existing data suggesting cost is a key barrier to AT access for both organizations providing AT and people with disabilities to obtain AT. Conclusion While this paper is the first to demonstrate that a targeted investment in AT systems and policies at the national level can have a resulting impact on the nature and strength of the AT, it only measures outcomes at one-year after investment. Further longitudinal impact evaluation would be desirable. Nonetheless, the results support the potential for systemic investments which leverage inter-organizational relationships and prioritize financial accessibility of AT, as one means of contributing towards increased access to AT for all, particularly in low-income settings.
