PCP42 - ECONOMIC EVALUATION OF INTELLIGENT ROLLATORS – ESTIMATING THEIR BENEFITS

      Intelligent rollators have the potential to support elderly to live independently at their familiar homes. They could be implemented in insurance baskets and their costs could be reimbursed by statutory health insurance to increase their use and affordability. However, to implement these technologies, their effectiveness and efficiency has to be shown. So far economic studies evaluating intelligent rollators and indicators that are able to show their outcomes and benefits for economic evaluation are missing. Therefore, this research has the aim to generate a set of indicators for the evaluation of intelligent rollators using scenario technique. A heuristic causal model was developed based on the model of functioning and disability. The causal model shows the complexity and associations between the use of intelligent rollators and their effects on the user and the health insurance system. Thereafter, a systematic literature review in the databases PubMed, IEEE, CINAHL and Gerolit as well as a hand search was performed to identify studies that have evaluated the outcomes of traditional and intelligent rollators. Based on the results of this review, indicators are identified and classified according to the aims of the user and decision-makers for economic evaluation. The user have the aim to use the intelligent rollator for compensating their impairments, to be mobile and to be able to participate in society. Decision-makers that decide on the reimbursement aim to offer devices that can compensate for impairments and that are economically justifiable, too. The categorisation of the identified indicators resulted in the following dimensions: quality of walk, mobility, physical effort, falls, functional status, user satisfaction, mobility-associated participation and reduced costs. The research shows the need to adapt common methods used in economic evaluation to the characteristics of assistive technologies. As a next step, the indicators have to be evaluated and validated.
