Strategies to collect consistent, accurate, and up-to-date information may vary from the bottom-up to national levels. First, Minimum Uniform Data Sets collected by wheelchair services can be a strategy. For instance, ISWP Minimum Uniform Dataset for International Wheelchair Service and Provision is an available resource. Second, at the national level, population census or surveys should include questions related to functioning and as it pertains to wheelchairs, those who are unable (or is very difficult) to walk. For example, the National Health Survey in the United States [39]or the Survey of Disability, Ageing and Carers in Australia[40]have done this and report that 0,7% and 0,9% of their country’s population use wheelchairs respectively. Engaging government officials, policy makers, and disability leaders is necessary in the advocacy efforts to reach commitment to this type of strategies. Research on how to measure the characteristics of people mobility impairments is also needed to support evidence-informed decision making [41].
To promote buy-in and encourage leadership from all relevant stakeholders, especially those in the field, such as DPOs, NGOs, and professional organizations, a stakeholders meeting based on WHO’s package is a strategy to share and hear the perspectives of the other stakeholders on the result of this situational analysis and to insure that the participation of people with disabilities is promoted, and their views and ideas heard [25].
