People with disability are disproportionately impacted by disaster events. They are two to four times more likely to die in a disaster, experience higher risk of injury and loss of property, have greater difficulty evacuating, sheltering, and require more intensive health and social services during and after disaster. While these impacts stem from a range of factors that increase the vulnerability of people with disability to disaster, a significant barrier to the safety and well-being of people with disability is their absence from emergency management practice and policy formulation. In 2014, the United Nations Office for Disaster Risk Reduction recognized this as a universal challenge. Global Disability-Inclusive Disaster Risk Reduction (DIDRR) initiatives and policy advocacy has helped to advance the incorporation of accessibility, inclusion, and universal design principles into the Sendai Framework for Disaster Risk Reduction (SFDRR) 2015–2030. DIDRR requires shared responsibility of multiple stakeholders working together to identify and remove barriers that increase risk for people with disability before, during, and after disaster. Yet, governments and emergency personnel are faced with the intractable problem of how to develop shared responsibility between local government, emergency personnel, people with disability, and the services that support them. Methods, tools, and programmatic guidance are needed to ensure that people with disability and their support needs are at the center of emergency management. The Person-Centered Emergency Preparedness (P-CEP) framework and process tool offers a new approach for enacting DIDRR; shifting emphasis to preparedness by people with disability in partnership with emergency personnel. The P-CEP was developed through a co-design process involving multiple stakeholders, including people with disability and their support networks. Grounded in the Capability Approach, the P-CEP integrates factors that facilitate personal emergency preparedness together with principles of person-centered planning to enable emergency managers to learn about the preparedness, capabilities, and support needs of people with disability and work together with people and the services that support them toward the development of local community-level DIDRR. The P-CEP takes an all-hazards approach by incorporating self-assessment and tailored preparedness planning for disasters triggered by natural hazard events and other emergencies (e.g., house fire, pandemic). The P-CEP has three components: (a) a capability framework consisting of eight elements to support self-assessment of strengths and support needs; (b) principles guiding the joint effort of multiple stakeholders to enable tailored emergency preparedness planning; and (c) four process steps enabling the developmental progression of preparedness actions and facilitating linkages between people with disability, their support services, and emergency personnel. The P-CEP is being used to advance individual and shared responsibilities for DIDRR in Australian communities through the incremental development of awareness about and responsiveness to the support needs that people with disability have in emergencies. Future research will apply P-CEP to the design of programs and services that: (a) increase the emergency preparedness of people with disability; and (b) ensure that information about the extra supports that people with disability need in emergencies is included in the design of disability-inclusive emergency planning.
