Objectives A research group based at St. Mary's Research Centre, St. Mary's Hospital, Montreal, has conducted a research program over the past two decades that aims to inform improvements in the management of depression in primary care and general medical settings, among older adults. This paper reviews the findings from this research program, discusses the findings in the context of other research, and highlights the implications for practice and health policy.Methods Narrative review and synthesis of 25 published articles, that included: 4 systematic reviews, 10 observational studies, 9 intervention trials, and 2 consensus conference reports.Results The results pertain to 4 research areas: detection of depression in primary care and general medical settings; collaborative care of depression; depression self-care interventions; and the role of family and friends in supporting depression self-care interventions.Conclusions We propose six recommendations for improving the management of depression in the target population. 1) Depression detection and treatment can be improved through collaborative care models that involve primary care physicians, mental health specialists and non-physician mental health workers who are trained to assist with the detection of depression, with the delivery of brief, low-intensity psychological interventions and with self-care support. More research and evaluation are necessary to determine the factors that enhance the effectiveness, cost-efficiency, and consumer-centeredness of these interventions. 2) Supported depression self-care (and other low-intensity interventions such as short problem-solving therapy) offered by telephone or via internet, either as part of collaborative or usual care are feasible treatment options but more research is necessary to determine their effectiveness in different clinical populations. Some populations (e.g., those aged 75 and over, with visual and/or mild cognitive impairment) are likely to need greater or face-to-face support. 3) As most family physicians are unlikely to have the necessary time or interest to support depression self-care interventions, other sustainable programmatic contexts are needed for delivery of these interventions. Options include: nurses or other mental health workers in multidisciplinary family medicine groups; regional mental health programs; and voluntary organizations dedicated to assisting in the management of chronic illnesses. Research is needed on the feasibility and effectiveness of using peer support workers or volunteers to provide coaching of depression self-care interventions. 4) Involvement of family or friends in depression self-care may improve outcomes (e.g., dyadic interventions) but further research is necessary. 5) Further research should explore the potential of depression self-care interventions to prevent major depression and in depression relapse prevention in this population.

There is no systematic or standardized approach to assessing higher mental functions in hospitalized elderly patients, despite the constant presence of nursing staff. The Confusion Assessment Method (CAM) is the only valid and reliable clinical tool for detecting symptoms of delirium easily and quickly, even by health professionals with no specialized training in psychiatry. The CAM has been translated into eight languages, but no validated French-language version has been published as yet. It was in response to this need that the researchers took the first steps in validating a French-language version of the CAM and the diagnostic algorithm, and enhanced the description in French of symptoms of delirium and the criteria of the diagnostic algorithm. The validation process was based on the first two steps in the transcultural validation method for psychological questionnaires suggested by Vallerand. The availability of a French-language version of this instrument will lead to greater professional autonomy and help to simplify the recognition of symptoms of delirium and ensure that the appropriate action is taken sooner.
