Whether by reducing the cost of antiretroviral drugs for HIV by 99% in 10 years, increasing the number of people receiving malaria treatment from 11 million in 2005 to 331 million in 2011, 1 or doubling the number of women receiving contraceptive implants in 4 years while saving donors and governments $240 million, 2 market shaping has addressed market barriers at scale. Market shaping interventions can play a role in enhancing market efficiencies, improving information transparency, and coordinating and incentivising the numerous stakeholders involved in both demand and supply-side activities. Examples of market shaping interventions include: pooled procurement, de-risking demand, bringing lower cost and high-quality manufacturers into global markets, developing demand forecasts and market intelligence reports, standardising specifications across markets, establishing differential pricing agreements, and improving service delivery and supply chains.

This document is divided into two chapters:
Wheelchairs are one of the most commonly used assistive devices; WHO estimates that 1% of the population, approximately 75 million people globally, require a wheelchair. 3 Those needing wheelchairs are those with mobility limitations and may include people born with congenital abnormalities, people with developmental and neurological conditions, such as cerebral palsy or muscular dystrophy, people with a spinal cord injury, people with musculoskeletal conditions such as lower limb amputation, people living with physical impairment which can be a result of polio or non-communicable diseases (NCDs) such as diabetes or stroke, and older people with gradual functional decline.
Four in five people who need a wheelchair live in LMICs, 4 and these countries account for the highest unmet need. While 90% of people with a need in high-income countries (HIC) are estimated to have a wheelchair, 5 this number is likely closer to 5% in LMICs. It is estimated that 64 million people need a wheelchair in LMICs (Table 1). This represents a crude estimate of need due to the lack of data available.
TABLE 1: MARKET SIZING FOR WHEELCHAIR NEED
10An appropriate wheelchair is defined as one that: meets the user's needs and environmental conditions; provides proper fit and postural support; is safe and durable; is available in the country; and can be obtained and maintained and services sustained in the country at an affordable cost. 10 The use of an appropriate wheelchair enhances users' personal mobility, which is a precondition for active participation in education, employment and civic life.
Being properly fitted with an appropriate wheelchair is critical to a user's health and quality of life. Proper fitting helps prevent various secondary health conditions such as: pressure sores and progression of postural deformities or contractures; respiration and digestion complications; and, in cases of people with spinal cord injuries and similar conditions, premature death. 11 A study from Sri Lanka showed that 75% of people with spinal cord injuries admitted to hospital died within 18-24 months from secondary complication because of their injuries; however, when healthcare training and appropriate equipment provision improved – including appropriate wheelchairs with cushions – the incidence of pressure sores reduced by 71% and repetitive urinary tract infection decreased by 61% within two years. 12
WHO categorises wheelchairs as follows:

In light of contextual realities, a consensus-driven process supported the development of the WHO Guidelines for the Provision of Manual Wheelchairs in Less Resourced Settings. The WHO Guidelinesemphasise eight 13 steps for appropriate wheelchair service (known as the WHO 8-Steps– see Figure 3) to assist stakeholders in developing an appropriate wheelchair provision system in different country contexts. 16 Following the release of the Guidelines in 2008, WHO developed the Wheelchair Service Training Package (WSTP) to support training.
Examples of USAID global investments include:
The global market for wheelchairs was estimated between US$4.0-4.5 billion 23 in 2018 with the United States and Western Europe accounting for about 40% and 20%, respectively. Manual wheelchairs make up about 60% of the sales revenue globally and are projected to grow 6% year-on-year. The powered wheelchairs segment is projected to grow faster at 15-20%. 24
A small number of LMIC governments procure wheelchairs directly and provide them through facilities and programmes under health, education, and/or social welfare ministries/departments. In these instances, wheelchairs are typically tendered for at the country or regional level, generally based solely on cost. Procurement and distribution or provision is often fragmented across different ministries, which leads to a variety of challenges, including: no single ministry having complete oversight on procurement and 17 provision within government or across partners; different ministries have differing levels of infrastructure or human resources to deliver and maintain wheelchairs; some ministries lack the supply chain or logistics capacity to effectively deliver products appropriately, which leads to a mass distribution model, whereby one wheelchair type is given out with limited service; different ministries have differing mandates on the population served and therefore some populations are left behind.
Some social enterprises have attempted to fill market gaps through a cross-subsidisation model. These social enterprises have designed products for users in both HICs and LMICs by considering the profile of users in HIC that are typically brand-conscious and performance-sensitive as well as the environmental condition in LMICs. The product is then offered at differential price points to allow larger margins gained from HICs market to subsidise sales in LIMCs market. Despite this promising model, these enterprises are 18 still limited by lack of capital, limited brand awareness to buyers in one or both markets, competition with insurance markets and low volume.
LDS Charities often complements their product offering by purchasing other wheelchair types to support local suppliers and fill gaps in need; however, their own branded products designed and produced in partnership with Colors ‘N Motion Inc. now consist of standard, urban active, and rough-terrain active wheelchairs. 27
However, ISO 7176 does not test for factors typical for LRS such as rough terrain and environmental conditions, such as high humidity, exposure to water and sand, and high temperature that differ from HICs. Premature failures of wheelchairs in LRS may be due to shortcomings in product regulations, quality standards and testing. The community recommended that more rigorous standards be developed for wheelchairs in LRS as they are subject to these unique environmental and use conditions. 29
To improve reliability and usability of wheelchairs in LRS and guide product design, ISWP developed and published the Design Considerations for Wheelchairs Used in Adverse Conditions. 30 The document was created to complement the WHO Guidelinesby providing more detailed information in designing wheelchairs for adverse environment and common pitfalls to avoid. In addition, ISWP developed protocols and equipment to test casters, rolling resistance and corrosion for adverse conditions, labelling it the ISO-Plus, but no specific pass/fail thresholds have been determined as of now.
At the moment, most LMICs include limited specifications in their tenders, often even restricting the request to a single word, such as “wheelchairs”. As a result, these countries may buy products that are not appropriate for their settings or for the users and lack desirable product features, including quality. The WHO, under the GATE Initiative, is developing Assistive Product Specifications (APS) for all assistive products listed in the Priority Assistive Products List, 31 including wheelchairs. The APS should be adapted to the local context and aims to serve as a set of objective specifications to support procurement and guide suppliers about market needs. The APS for wheelchairs should be available in late 2019.
