Effect of deinstitutionalisation for adults with intellectual disabilities on costs: a systematic review.

OBJECTIVE: To review systematically the evidence on the costs and cost-effectiveness of deinstitutionalisation for adults with intellectual disabilities. DESIGN: Systematic review. POPULATION: Adults (aged 18 years and over) with intellectual disabilities. INTERVENTION: Deinstitutionalisation, that is, the move from institutional to community settings. PRIMARY AND SECONDARY OUTCOME MEASURES: Studies were eligible if evaluating within any cost-consequence framework (eg, cost-effectiveness analysis, cost-utility analysis) or resource use typically considered to fall within the societal viewpoint (eg, cost to payers, service-users, families and informal care costs). SEARCH: We searched MEDLINE, PsycINFO, CENTRAL, CINAHL, EconLit, Embase and Scopus to September 2017 and supplemented this with grey literature searches and handsearching of the references of the eligible studies. We assessed study quality using the Critical Appraisals Skills Programme suite of tools, excluding those judged to be of poor methodological quality. RESULTS: Two studies were included; both were cohort studies from the payer perspective of people leaving long-stay National Health Service hospitals in the UK between 1984 and 1992. One study found that deinstitutionalisation reduced costs, one study found an increase in costs. CONCLUSION: A wide-ranging literature review found limited evidence on costs associated with deinstitutionalisation for people with intellectual disabilities. From two studies included in the review, the results were conflicting. Significant gaps in the evidence base were observable, particularly with respect to priority populations in contemporary policy: older people with intellectual disabilities and serious medical illness, and younger people with very complex needs and challenging behaviours.

Effect of deinstitutionalisation on quality of life for adults with intellectual disabilities: a systematic review.

OBJECTIVE: To review systematically the evidence on how deinstitutionalisation affects quality of life (QoL) for adults with intellectual disabilities. DESIGN: Systematic review. POPULATION: Adults (aged 18 years and over) with intellectual disabilities. INTERVENTIONS: A move from residential to community setting. PRIMARY AND SECONDARY OUTCOME MEASURES: Studies were eligible if evaluating effect on QoL or life quality, as defined by study authors. SEARCH: We searched MEDLINE, PsycINFO, CENTRAL, CINAHL, EconLit, Embase and Scopus to September 2017 and supplemented this with grey literature searches. We assessed study quality using the Critical Appraisal Skills Programme suite of tools, excluding those judged to be of poor methodological quality. RESULTS: Thirteen studies were included; eight quantitative studies, two qualitative, two mixed methods studies and one case study. There was substantial agreement across quantitative and qualitative studies that a move to community living was associated with improved QoL. QoL for people with any level of intellectual disabilities who move from any type of institutional setting to any type of community setting was increased at up to 1 year postmove (standardised mean difference [SMD] 2.03; 95% CI [1.21 to 2.85], five studies, 246 participants) and beyond 1 year postmove (SMD 2.34. 95% CI [0.49 to 4.20], three studies, 160 participants), with total QoL change scores higher at 24 months comparative to 12 months, regardless of QoL measure used. CONCLUSION: Our systematic review demonstrated a consistent pattern that moving to the community was associated with improved QoL compared with the institution. It is recommended that gaps in the evidence base, for example, with regard to growing populations of older people with intellectual disability and complex needs are addressed.
