A scoping review of clusters of multiple long-term conditions in people with intellectual disabilities and factors impacting on outcomes for this patient group

Abstract

People with intellectual disabilities (ID) are vulnerable to multiple long-term conditions (MLTC). However, in the UK, there are no individual strategies tailored for them. This study synthesised evidence on prevalence of MLTC in people with ID alongside risk factors, outcomes and preventative strategies. The scoping review used the tool Abstrackr to search retrieved articles from three bibliographic databases. Of 933 articles initially screened and further identified, 20 papers met our inclusion criteria. Our findings revealed significant data on prevalence of MLTC in people with ID across the studies, but very limited data on clusters or patterns of co-occurrence in this population. The majority of papers explored risk factors and strategies for prevention of MLTC, but far fewer compared outcomes by MLTC. The identified gaps in the literature indicate the need for further research to identify clusters of MLTC and tailored prevention strategies to reduce poor outcomes in this population.
