Наслов: | Association between benzodiazepine premedication and 30-day mortality rate | Authors: | Kowark, Ana Berger, Moritz Rossaint, Rolf Schmid, Matthias Coburn, Mark POSE Study Group Naumovski, Filip |
Issue Date: | 25-ное-2021 | Publisher: | Ovid Technologies (Wolters Kluwer Health) | Journal: | European Journal of Anaesthesiology | Abstract: | Recent guidelines suggest that benzodiazepine premedication should be avoided in elderly patients, though with limited supporting evidence. We conducted a secondary analysis of the POSE data to explore the association of premedication in patients aged 80 years or older with 30-day mortality. We used propensity score methods to perform a confounder-adjusted time-to-event analysis of the association between benzodiazepine premedication and 30-day mortality of the POSE study. POSE was conducted as a European multicentre prospective cohort study. PATIENTS Adults aged 80 years or older scheduled for surgical or nonsurgical intervention under anaesthesia. RESULTS A total of 9497 patients were analysed. One thousand five hundred and twenty-one patients received benzodiazepine premedication, 7936 patients received no benzodiazepine premedication, 30 received clonidine and 10 had missing premedication data. Inverse propensity-score-weighted log-rank analysis did not provide unambiguous evidence for an association between benzodiazepine premedication and 30-day mortality; median [range] <jats:italic toggle="yes">P</jats:italic> = 0.048 [0.044 to 0.078], estimated 30-day mortality rates 3.21% and 4.45% in benzodiazepine-premedicated and nonbenzodiazepine-premedicated patients, respectively. Inverse propensity-score-weighted Cox regression resulted in a hazard ratio of 0.71 (95% CI 0.49 to 1.04), pointing at a possible reduction of 30-day mortality in the benzodiazepine premedication group. Sensitivity analyses, which constituted subgroup, matched-pairs, and sub classification analyses, resulted in similar findings. CONCLUSION This secondary analysis of the POSE data did not find evidence for an unambiguous association between benzodiazepine premedication and 30-day mortality. Point estimates indicated a reduction of 30-day mortality in benzodiazepine-premedicated patients. The results presented here might be affected by unmeasured confounding factors, which could be addressed in a randomised trial. | URI: | http://hdl.handle.net/20.500.12188/31372 | DOI: | 10.1097/eja.0000000000001638 |
