Objective: to investigate the effects of supported discharge after an acute
admission in older people with undifferentiated clinical problems.
Design: a systematic review of randomized controlled trials.
Methods: we searched MEDLINE, CINAHL, the Cochrane Library, PsycLit and the
Social Science Citation Index up to the end of 1997. This was augmented by
hand-searching, follow-up of bibliographies and direct enquiry of authors
of included studies. Application of inclusion decisions, quality assessment
and data abstraction were carried out independently by at least two of the
reviewers. We tabulated the results of the included studies and used meta-
analysis where appropriate to refine conclusions.
Results: we finally included nine studies in the review, assessment of whic
h revealed that bias was present, dictating the need for caution in interpr
eting results. Despite this, there was relative certainty that the proporti
on of those at home 6-12 months after admission is greater with supported d
ischarge (odds ratio 1.4, 95% confidence interval 1.1- 2.0). This was assoc
iated with a consistent pattern of reduction in admission to long-stay care
over the same period, without apparent increases in mortality. There was u
ncertainty about the effect of supported discharge on hospitalization. Ther
e were no rigorous research data on functional status, patient and carer sa
tisfaction, and, in consequence, uncertainty about the overall effectivenes
s of supported discharge.
Conclusions: we believe that the results of this review provide reassurance
that supporting discharge from hospital to home is of value. However, impo
rtant sources of uncertainty remain, suggesting the need for further resear
