Variations in structures, processes and outcomes of community mental health teams for older people: a systematic review of the literature.
OBJECTIVE
In the UK and elsewhere, specialist community mental health teams (CMHTs) are central to the provision of comprehensive services for older people with mental ill health. Recent guidance documents suggest a core set of attributes that such teams should encompass. This article reports on a systematic literature review undertaken to collate existing evidence regarding the structures and processes of CMHTs for older people and to evaluate evidence linking approaches to effectiveness.


METHODS
Relevant publications were identified via systematic searches, both electronic and manual. Searches were limited to the UK for descriptions of organisation and practice but included international literature where comparisons between different CMHT arrangements were evaluated. Empirical, peer-reviewed studies from 1989 onward were included, extended to non peer-reviewed nationally or regionally representative reports, published after 1998, for the descriptive element.


RESULTS
Forty-five studies met inclusion criteria of which seven provided comparative outcome data. All but one were UK based. The most robust evidence related to research conducted in exemplar teams. Limited evidence was found regarding the effectiveness of many of the core attributes recommended in policy directives although their presence was reported in much of the literature.


CONCLUSIONS
The contrast between presentation and evaluation of attributes is stark. Whilst some gaps can be filled from related fields, further research is required that moves beyond description to evaluation of the impact of team design on service user outcomes in order to inform future policy directives and practice guidance. A framework for an evidence-based model of CMHTs for older people is provided.
