A systematic review of Intensive Comprehensive Aphasia Programmes – who takes part, what is measured, what are the outcomes?

Purpose: This study synthesizes participant and outcome data from peer-reviewed Intensive Comprehensive Aphasia Programme (ICAP) studies. Methods: A systematic review was conducted following PRISMA guidelines. Study eligibility criteria were specified in relation to population, intervention, comparison, outcome, and design considerations. Data were extracted according to six research questions. Narrative synthesis was used. Results: Twenty-one studies were included covering 13 ICAPs (N = 485, aged 18–86 years, between 11 and 335 months post-stroke). Twenty-seven participant selection criteria were identified. Fifty-six outcome measures spanning the WHO-ICF were used, with the majority assessing the body function domain. Only eight studies employed an experimental design with data appropriate for analysis and synthesis. Risk of bias was noted across this sub-group. Participants improved in word-finding, communication, activity/participation, and communication-related quality of life, and maintained their gains; however, except for word finding, evidence of effect came from isolated studies. Factors influencing outcomes were rarely considered. Some drop-outs, missed sessions, and fatigue were noted. Some studies reported IPD alongside group analyses. Conclusions: ICAP selection criteria need justification and should contribute to the understanding of candidacy for this treatment model. Rationalisation of ICAP treatment content and outcome measurement is required, spanning all WHO-ICF domains. Employment of the core outcome set for aphasia would enable data synthesis and facilitate comparisons between the ICAP and other therapy models. Implications for Rehabilitation: Healthcare professionals can use this review to appreciate that the evidence base for intensive and comprehensive aphasia programmes is emerging and based on studies of varying methodological quality and thus findings are not conclusive. Patients across the lifespan and across a range of aphasia severities, and patients who are independent or have support for activities of daily living, can participate in intensive and comprehensive aphasia programmes. Patients can expect improved word finding ability from participation in an intensive and comprehensive aphasia programme, and some patients can experience benefits in functional communication, communication confidence, and aphasia-related quality of life. Outcome measurement from intensive and comprehensive aphasia programmes should encompass language functioning, communication activities/participation, quality of life, and outcomes for family members, and ideally environmental and personal factors should be considered.
