IN ORDER TO FULLY EVALUATE and manage a service, one should be able to answer all parts of the question ?Who receives what services, from whom, at what cost, and with what effect??1 While there is good information on the first four elements, mental health services generally do less well in demonstrating the effectiveness of what they do, and it is here that routine outcome measurement (ROM) can make a contribution. Despite the very real progress that has been made in implementing ROM in Australia it is evident from a variety of sources, formal and informal, that not everyone is convinced of its necessity or value.

The Project represented a considered, innovative approach to dealing with poor collaboration between the public mental health sector, private psychiatrists and GPs. The Linkage Unit achieved significant systems-level and cultural change, which has the potential to be sustained. Expanded roles for private psychiatrists, particularly supervision and training, may improve collaboration, and warrant further exploration in terms of costs and benefits.

Background: While effective interventions have been developed to support families where a parent has a mental illness in Adult Mental Health Services, embedding and sustaining them is challenging resulting in families not having access to support. This study developed an explanatory model of influencers that had enabled sustainability of the Let's Talk intervention in one service. Methods: A participatory case study was used to build an explanatory model of sustainability at the service using theoretical frameworks. Qualitative and quantitative data was collected about practitioner's practice and the organisation's implementation process and capacity to support practice. A local research group worked with the researcher using a transforming data approach through description, analysis and interpretation. Results: Influencers were grouped into four major categories: (1) External social, political and financial context, (2) Resources, (3) Prior organisational capacity and (4) Sustainability Factors. The last category, Sustainability factors, was divided into three subcategories: (4.1) Practitioner (4.2) Organisation and (4.3) Parent-Client. These categories form part of an explanatory model for the key influencers of continued practitioner practice and organisational capacity to support practice. Conclusions and implications for practice: In this case study, the pre-existing organisational context along with practitioner, organisation and parent-client factors operated together to influence sustainability. The results suggest that sustainability is more likely to be supported by both linking Let's Talk to existing organisational identity, capacity, structures and relationships and by supporting mutual adaptations to improve the fit. Additionally, by understanding that setbacks are common and ongoing adjustments are needed, implementers are able to have realistic expectations of sustainability.

A number of barriers to public sector clinicians and private psychiatrists collaborating in shared care arrangements were identified. The two groups surveyed identified similar barriers. Some of these can potentially be addressed by changes to service systems. Others require cultural shifts in both sectors. Improved communications including more opportunities for formal and informal meetings between people working in the two sectors would be likely to improve the understanding of the complementary sector's perspective and practice. Further changes would be expected to require careful work between the sectors on training, employment and practice protocols and initiatives, to allow better use of the existing services and resources.
