Current government policy emphasises professional accountability, Best Value, evidence-based practice and outcomes for users and carers. In this context, being able to demonstrate the effectiveness of routine practice is increasingly important. This article considers the key issues in collecting information about the outcomes of equipment and adaptations. These include: the assessment of the full range of outcomes; the timing of data collection; the use of standardised and individualised measures; and linking outcomes to interventions. Three approaches to evaluating the outcomes of equipment and adaptations are distinguished: functional status measures; health status or quality of life measures; and indirect approaches. Examples of each approach are provided and their strengths and limitations discussed. Previous work on the outcomes of equipment and adaptations has neglected the perspectives of carers and the impact of service delivery (service process outcomes); further work on these areas is needed to ensure that all the outcomes of equipment and adaptations are fully evaluated.
