Developing an outcome measure for an adult intellectual disabilities intensive support team – a practice paper

Purpose This paper aims to outline the initial pilot use of the client complexity matrix (CCM), an outcome measure developed for an NHS Adult Intellectual Disabilities Intensive Support Team (IST) in the West Midlands of England. Design/methodology/approach A mixed method approach was used to report the results and evaluate the use of the CCM within this IST. The CCM was trialled for six months between January 2022 and June 2022. CCM scores pre and post IST intervention were analysed via t-test, and qualitative feedback from clinicians is detailed. Findings Analysis suggests the CCM captures service success showing a significant decrease in complexity and risk post-intervention. Qualitative comments from clinicians were generally positive; however, there were requested changes regarding specific presentations, use of labels/language and for a digital version. Research limitations/implications The tool is not co-constructed with the client. Because of this IST’s caseload, the sample size was small. Only one clinician was asked to complete the CCM pre and post intervention. Future use of the measure will encourage two clinicians to complete the measure to evidence its inter-rater reliability. Each client’s specific presentation was not explicitly analysed here. Practical implications The CCM will be updated using the feedback from clinicians and from the peer review process. Research that examines the generalisability of this measure to other IST services would be beneficial. Originality/value The CCM appears to fill a gap in outcome measurements for this IST service which looks at breadth and depth of client complexity and risk.
