Complex intervention in augmentative and alternative communication (AAC) care in Germany: a study protocol of an evaluation study with a controlled mixed-methods design

摘要

IntroductionThe current practice of service delivery in Germany for people with complex communication needs (CCN) who are in need of augmentative and alternative communication (AAC) is characterised by diverse problems, including a lack of clarity in the responsibilities of the service providers involved. To address these issues a new service delivery model has been put in place, implemented in three AAC counselling centres for patients with a particular health insurance across Germany. The implementation of a new service delivery model aims to improve individualised service delivery. The model goes beyond standard care by adding case management, counselling, AAC training and, if needed, AAC therapy. This study aims to evaluate the effectiveness of this complex intervention.
