Assessed the difficulties encountered by general practitioners in the care of the elderly with complex medical and psycho-social conditions, their knowledge of the geriatric network, the interest engendered by setting-up mobile community based geriatric units.The survey was both qualitative and quantitative and took the form of a telephone interview and a multimodal questionnaire (telephone interview, postal or email questionnaire) of general practitioners in the areas of Annecy, Grenoble and Roanne (France).Sixty five per cent of the 129 GPs contacted by telephone said the survey interested them. One hundred and eleven physicians replied to the questionnaire. The first priority for intervention of the mobile geriatric unit should be the management of the elderly with cognitive disorders and behavioural symptoms (43 replies) that pose the most problems for physicians. The mobile team should be available, and easy to contact rapidly. The request for intervention should be made by the GP (69 replies, 72.6%), by telephone (95 replies, 86%) and the visit made within the following 48 - 72 hours (60 replies, 67.4%).Our results confirm the existence of difficulties in the care the elderly people with complex conditions that justify experimentation of community mobile geriatric teams.

Improving care and health course for hospitalized elderly patients is one of the tasks set out in the "Rapport du parcours de santé des PAERPA" (elderly people with or at risk of functional decline). Identification of the needs of a mobile geriatric team (MGT) intervention for the patients remain difficult in emergency department and in medical surgical units. A screening tool is needed and should be simple and fast to use. Its implementation implies that it is efficient and previously validated. The aim of our study was to evaluate the validity and predictive performances of the Triage risk stratification tool (TRST) for identify patients aged over 75 years, requiring the intervention of the MGT. This is a prospective, national, multicenter study including consecutive patients aged 75 years and older, hospitalized in emergency services and medical-surgical units in September and October 2013. The TRST was considered positive when the score was greater than 2 of 5 points. A supplementary question with binary answer (yes/no) was asked to MGT, in order to define if MGT intervention was useful. This issue has served as a "gold standard" for assessing the validity and predictive test performance. In emergency departments, the TRST was performed in 427 patients, 347 were positive. Results showed high sensitivity (79%), and poor specificity (19%) of the test in emergency units, showing that TRST did not permit to identify patients requiring MGT intervention. In contrast, the TRST seems more performant in medical-surgical (n=63 patients) units with good predictive performances (positive predictive value 90% and negative predictive value 87%). The specificity of TRST in emergency services is insufficient to generalize its use. However, performances of the TRST in other units are encouraging to propose a validation as part of a national research project.
