Prescription of benzodiazepines and Z-drugs among older patients in primary care: a French, national, cohort study

Abstract

Abstract Background In France, general practitioners (GPs) prescribe benzodiazepines and Z-drugs (BZD/ZDs) widely, and especially to older adults. Several characteristics of patients and/or GPs linked to BZD/ZD overprescription have been described in the general population but not among older patients in primary care. Objectives To estimate the proportion of GP consultations by patients aged 65 and over that resulted in a BZD/ZD prescription, and determine whether any GP-related factors predicted BZD/ZD overprescription in this setting. Methods We analyzed sociodemographic and practice-related GP characteristics, and aggregated data on consultations recorded prospectively by 117 GPs in a database between 2000 and 2010. Next, we used logistic regression models to look for factors potentially associated with BZD/ZD overprescription (defined as an above-median prescription rate). Results The GPs’ mean age at inclusion was 47.4 (7.1), and 87.9% were male. During the study period, the median (95% confidence interval) proportion of consultations with patients aged 65 and over resulting in a BZD/ZD prescription was 21.8% (18.1–26.1) (range per GP: 5–34.1%). In a multivariable analysis, a greater number of chronic disease (OR [95% CI] = 2.10 [1.22–3.64]), a greater number of drugs prescribed per consultation (5.29 [2.72–10.28]), and shorter study participation were independently associated with BZD/ZD overprescription. Conclusions BZD/ZD overprescription was associated with a greater chronic disease burden and the number of drugs prescribed per consultation but not with any sociodemographic or practice-related GP characteristics. Targeted actions are needed to help GPs limit their prescription of BZD/ZDs to older patients with multiple comorbidities and polypharmacy.
