Abstract

Background Ertapenem, cefepime, imipenem, ofloxacin, ceftazidime, clarithromycin, cefaclor, levofloxacin, linezolid, moxifloxacin, azithromycin, piperacillin-tazobactam, trimethoprim-sulfamethoxazole, metronidazole, ciprofloxacin, and cefuroxime are known to be associated with delirium. Other antibiotics may also lead to delirium, but no study has systemically compared delirium associations for many available antibiotics.

Objective The objective of this study was to evaluate the association between delirium and antibiotics using the FDA Adverse Event Reporting System (FAERS).

Methods FAERS reports from January 1, 2004 to December 31, 2018 were included in the study. Reporting odds ratios (RORs) and corresponding 95% confidence intervals (95% CI) for the association between antibiotics and delirium were calculated. An association was considered to be statistically significant when the lower limit of the 95% CI was greater than 1.0.

Results A total of 10,015,622 reports (including 16,982 delirium reports) were considered, after inclusion criteria were applied. Statistically significant delirium RORs (95% CI) for antibiotics were: ertapenem 21.07 (16.38-27.10), cefepime 9.8 (6.37-15.09), imipenem 9.68 (6.75-13.89), ofloxacin 7.73 (4.00-14.92), ceftazidime 6.09 (2.73-13.62), clarithromycin 5.34 (4.37-6.53), cefaclor 5.32 (1.71-16.58), ampicillin-sulbactam 4.49 (2.13-9.45), levofloxacin 4.47 (3.88-5.16), linezolid 4.33 (3.28-5.72), moxifloxacin 3.51 (2.81-4.38), azithromycin 2.76 (2.09-3.64), piperacillin-tazobactam 2.41 (1.47-3.93), trimethoprim-sulfamethoxazole 2.36 (1.61-3.47), metronidazole 1.85 (1.31-2.60), ciprofloxacin 1.83 (1.44-2.33), and cefuroxime 1.81 (1.03-3.20).

Conclusion This study found statistically significant increased risk of reporting delirium with ertapenem, cefepime, imipenem, ofloxacin, ceftazidime, clarithromycin, cefaclor, ampicillin-sulbactam, levofloxacin, linezolid, moxifloxacin, azithromycin, piperacillin-tazobactam, trimethoprim-sulfamethoxazole, metronidazole, ciprofloxacin, and cefuroxime.
