Overuse of antidepressants in older outpatients with Alzheimer's disease and associated disorders: an observational study.

Forty per cent of French subjects over 65 years old with Alzheimer's disease and related disorders (ADRD) are chronically exposed to antidepressants, suggesting an overuse of these drugs. The main objective of our study was to estimate the prevalence of the overuse of antidepressants in this population and the factors associated with this. METHODOLOGY: a single-centre, prospective, cross-sectional study carried out at the Bretonneau outpatient department between 1st December 2014 and 31st May 2015. All patients aged 70 and above, suffering from ADRD (according to DSM IV criteria) and currently being prescribed an antidepressant were eligible. "Overuse" was defined as off-label prescriptions or prescriptions that went beyond the recommended duration of treatment. This was assessed by the geriatrician in charge and validated by an expert committee, who were blind to the geriatrician's assessment. RESULTS: Fifty-four patients were included in the study (mean age: 82.9 years (± 5.4); 70.4% women; 60% with mild to moderate dementia). The main indication of antidepressant treatment was a major depressive episode (59.3%). The geriatrician could not reach a conclusion on overuse in 10 cases (18.5%). Inter-rater agreement between geriatricians and the expert committee was good (kappa coefficient: 0.73 [0.5-0.95]). Finally, 33 (61%) of these patients were overusing antidepressants: a third had an off-label prescription and two thirds had exceeded the recommended treatment duration. The only factor associated with this overuse was co-prescription of psychotropic drugs (p = 0.009). CONCLUSIONS: the overuse of antidepressants is common in older patients with dementia, particularly overuse due to exceeding the treatment duration. This is significantly associated with co-prescription with another psychotropic drug, suggesting that this represents a more global problem of the overuse of psychotropic drugs.

Forty per cent of French subjects over 65 years old with Alzheimer's disease and related disorders (MATA) are chronically exposed to antidepressants suggesting an overuse of these drugs. The main objective of our study was to estimate the prevalence and factors associated with overuse by antidepressants in this population. METHODOLOGY: Single-center, prospective, cross-sectional study carried out at the Bretonneau Day Hospital (HDJ) between December, 1st 2014 and May, 31 2015. Consecutive patients with ≥70 years of age, suffering from MATA (according to DSM IV criteria) and current prescription of antidepressant were eligible. Overuse was defined by off-label prescriptions or prescriptions beyond the recommended duration of treatment. It was assessed by the geritrician in charge and validated by an expert committee, blind from the geriatrician's assessment. RESULTS: Fifty-four patients were included in the study (mean age 82.9 years (+/- 5.4), 70.4% of women, 60% with mild to moderate dementia). The main indication of antidepressant treatment was a major depressive episode (59.3%). The geriatrician could not deal with overuse for 10 cases (18.5%). Inter-rater agreement between geriatricians and expert committee was good (kappa coefficient 0.73 [0.5-0.95]). Finally 33 (61%) of these patients had overuse of antidepressants: 1/3 had an off-label prescription and 2/3 had an exceeded treatment duration. The only factor associated with this overuse was coprescription of psychotropic drugs (p=0.009). CONCLUSIONS: Antidepressant overuse is common in demented older outpatients, especially overuse due to exceeded treatment duration. It is significantly associated with coprescription with another psychotropic drug, suggesting that it fits into a more global problem of overuse in psychotropic drugs.

[What is the place of a geriatric follow-up ambulatory care unit in the structures developed by the 2008/2012 Alzheimer Plan?]. / Quelle est la place d’un hôpital de jour de suivi gériatrique au sein des structures développées par le Plan Alzheimer 2008/2012'.

UNLABELLED: The French 2008/2012 Alzheimer Plan is designed to improve the support given to elderly patients and their families. Objective: To describe the typology of the patients managed in a Geriatric multidimensional rehabilitation ambulatory care unit between 2008 and 2012. METHODS: Programme de médicalisation des systèmes d'information database concerning the number of concomitant diseases and several specific indicators. RESULTS: The number of patients increased between 2008 (109) and 2009 (293) but then remained stable (about 300). The differences between 2008 and subsequent years were statically significant for the number of concomitant diseases (p < 0.001) and the number of days/patients (p < 0.01), but not for 2009-2012. CONCLUSION: The variations seem to be related to implementation of the Alzheimer Plan and a change in the organization of French gerontology health networks.
