Providing efficient and effective aged care services is one of the greatest public policy concerns currently facing governments.
Increasing the integration of care services has the potential to provide many benefits including increased access, promoting
greater efficiency, and improving care outcomes. There is little research, however, investigating how integrated aged care
can be successfully achieved. The PRISMA (Program of Research to Integrate Services for the Maintenance of Autonomy) project,
from Quebec, Canada, is one of the most systematic and sustained bodies of research investigating the translation and outcomes
of an integrated care policy into practice. The PRISMA research program has run since 1988, yet there has been no independent
systematic review of this work to draw out the lessons learnt.Narrative review of all literature emanating from the PRISMA project between 1988 and 2012. Researchers accessed an online
list of all published papers from the program website. The reference lists of papers were hand searched to identify additional
literature. Finally, Medline, Pubmed, EMBASE and Google Scholar indexing databases were searched using key terms and author
names. Results were extracted into specially designed spread sheets for analysis.Forty-five journal articles and two books authored or co-authored by the PRISMA team were identified. Research was primarily
concerned with: the design, development and validation of screening and assessment tools; and results generated from their
application. Both quasi-experimental and cross sectional analytic designs were used extensively. Contextually appropriate
expert opinion was obtained using variations on the Delphi Method. Literature analysis revealed the structures, processes
and outcomes which underpinned the implementation. PRISMA provides evidence that integrating care for older persons is beneficial
to individuals through reducing incidence of functional decline and handicap levels, and improving feelings of empowerment
and satisfaction with care provided. The research also demonstrated benefits to the health system, including a more appropriate
use of emergency rooms, and decreased consultations with medical specialists.Reviewing the body of research reveals the importance of both designing programs with an eye to local context, and building
in flexibility allowing the program to be adapted to changing circumstances. Creating partnerships between policy designers,
project implementers, and academic teams is an important element in achieving these goals. Partnerships are also valuable
for achieving effective monitoring and evaluation, and support to 'evidence-based' policy-making processes. Despite a shared
electronic health record being a key component of the service model, there was an under-investigation of the impact this technology
on facilitating and enabling integration and the outcomes achieved.PRISMA provides evidence of the benefits that can arise from integrating care for older persons, particularly in terms of
increased feelings of personal empowerment, and improved client satisfaction with the care provided. Taken alongside other
integrated care experiments, PRISMA provides further evidentiary support to policy-makers pursuing integrated care programs.
The scale and scope of the research body highlights the long-term and complex nature of program evaluations, but underscores
the benefits of evaluation, review and subsequent adaptation of programs. The role of information technology in supporting
integration of services is likely to substantially expand in the future and the potential this technology offers should be
investigated and harnessed.
