Most of these originated in the UK or the USA and fell within the realist quality rating of "thick description". The synthesis involved using this new evidence to interrogate the utility of earlier programme theories. Overall, the results confirmed the importance of (i) collaborative care planning, (ii) reablement and (iii) integrated working as key to effective intermediate care delivery. However, the additional evidence drawn from the field of homelessness highlighted the potential for some theory refinements.First, that "psychologically informed" approaches to relationship building may be necessary to ensure that service users are meaningfully engaged in collaborative care planning and second, that integrated working could be managed differently so that people are not "handed over" at the point at which the intermediate care episodeends. This was theorised as key to ensuring that ongoing care arrangements do not break down and that gains are not lost to the person or the system vis-à-vis the prevention of readmission to hospital. schemes and empirical research on these is emerging.
| INTRODUCTIONThe paper begins with an overview of these recent developments in intermediate care for people who are homeless. We then outline the search strategy and the methods used to synthesise the literature on homelessness, before discussing how this additional evidence "speaks" to the conceptual framework for intermediate care proposed by Pearson et al. (2013Pearson et al. ( , 2015. In the final section, we draw out the implications for service development and future research, and also make recommendations about possible refinements to the original conceptual framework. This review is reported in accordance with the RAMESES publication standards for realist reviews (Wong, Greenhalgh, Westhorp, Buckingham, & Pawson, 2013). Long-term homelessness is characterised by "tri-morbidity", the combination of mental ill-health, physical ill-health, and drug and alcohol misuse (Hewett, Halligan, & Boyce, 2012).

What is known about this topic• Long-term homelessness is characterised by "tri-morbidity" (the combination of mental ill-health, physical illhealth, and drug and alcohol misuse).• Hospital discharge is often problematic for people who are homeless with high rates of readmission.• Much is known about the design and delivery of intermediate care services for older people, but less is known about how to meet the transitional care needs of people who are homeless. • A reconceptualisation of the intermediate care concept which is designed to prevent these short-term services from becoming "blocked".
