Plenty of activity but little outcome data: a review of the "grey literature" on primary care anxiety and depression programs in Australia.
To identify reports in the "grey literature" of programs conducted in Australian primary care to improve depression and anxiety outcomes, and to examine these reports for evidence of effectiveness.



A systematic search was undertaken for grey literature reports using primary health care research databases, community and professional websites, clearinghouse sources, government reports, and reports from the Australian General Practice Network. Reports were included if they related to programs targeting depression or anxiety, contained qualitative or quantitative effectiveness data, and were published during 1995-2006.



In total, 642 reports were identified, of which 43 met inclusion criteria. Of the 43 programs described, 30 were delivered in general practice, five in the community or residential care, three in schools, and five were Internet or computer based. Nine programs were also reported in the formal "black" literature, but most, including the Better Outcomes in Mental Health Care initiative, were not. Limited data on effectiveness or patient outcomes were available in the grey literature.



There is currently no single service that identifies, describes and catalogues the range and effectiveness of mental health initiatives in Australia. There may be a role for a mental health information "clearinghouse" to facilitate dissemination and education, and to promote collaboration among researchers, practitioners, consumers and policymakers. Innovative schemes to disseminate evidence-based models and to encourage the collection of data on patient outcomes in such programs are needed.
