Knowledge translation in ABI rehabilitation: A model for consolidating and applying the evidence for cognitive-communication interventions

Abstract

Primary objectives: (1) To propose a model for consolidating and disseminating existing evidence relevant to cognitive-communication interventions after ABI. (2) To present the Cognitive-Communication Intervention Review Framework (CCIRF). (3) To outline future considerations for applying evidence to clinical practice.

Research design: Employment of a model for knowledge translation.

Methods and procedures: Application of evidence requires synthesis and dissemination of information in an accessible format for end users. A literature search identified 20 systematic reviews (1997-2007) with a complex array of 72 practice recommendations relevant to cognitive-communication interventions. The CCIRF was used to synthesize the evidence within 11 intervention categories. Reviews were analysed according to: organization, population, intervention, comparison and outcome, with a focus on communication outcomes.

Main outcomes and results: Consolidated evidence revealed support for interventions relating to: social communication, behavioural regulation, verbal formulation, attention, external memory aids, executive functions and communication partner training. Research gaps were noted in the areas of comprehension (auditory/reading), written expression and vocational communication interventions. Similar recommendations emerge across reviews.

Conclusions: Implementation of the growing body of evidence for cognitive-communication interventions is challenged by variability in study populations, interventions, and research focus on communication. The CCIRF provides a means of promoting consistency in knowledge translation and application.
