IC61: Comparative Effectiveness Research: A Conceptual Model in Wheelchair Service Provision

With increasing awareness regarding Evidence-based practices, along with the introduction of policies and laws at the institutional and national levels that necessitates stringent record of interventions and their outcomes; the need for studies that evaluate effectiveness is on the rise. This increasing need has led to the new branch of science called the Comparative Effectiveness Research (CER). The Affordable Care Act defined CER as ‘‘research evaluating and comparing health outcomes and the clinical effectiveness, risks, and benefits of 2 or more health care interventions, protocols for treatment, care management, and delivery and any other strategies or items being used in the treatment, management, and diagnosis of, or prevention of illness or injury in, individuals.’’(Hartling, Vandermeer, & Fernandes, 2014) The primary purpose of CER is to assist various stakeholders of the health care delivery process in making informed decisions by advancing the quality and relevance of evidence available(Krishnan, Schatz, & Apter, 2011).

This instructional course will discuss literature explaining Comparative Effectiveness Research within the realm of Assistive Technology, and present a conceptual framework that would be applicable for the various stakeholders of the wheelchair service provision(America, 2011). The goal of this session is to present and discuss useful outcome measures that could be employed by clinicians and other stake holders to evaluate effectiveness during the process of wheelchair service provision.
