A decision support system for selecting augmentative and alternative communication devices

Abstract

The goal of this research is to improve access to services for patients in need of augmentative and alternative communication (AAC). The specific aim of this paper is to develop a decision-making model that evaluates an exhaustive list of AAC devices and recommends the best alternative(s) for the patient. The model maximises a best-fit function that considers the patient's disability profile and the capabilities of each device. Currently, there are multiple private and government companies that offer a large variety of devices targeting patients in need of AAC. However, the decision-making process of what device to try on the patient is largely based on the health professional's experience and familiarity with specific companies. The proposed decision-model has the capability of improving patient experience of care by reducing the assessment time required to find the best device.
