[Patient adherence in respiratory tract infections: ceftibuten versus other antibiotics (PARTICULAR study)]

Abstract

The study was conducted to evaluate patient compliance to antibiotic therapy in respiratory tract infections. The main aim of the study was to establish whether dosing frequency (1 vs 2 or 3 times daily) and other factors influence compliance. Patients aged 18 and over attending selected primary health facilities in Lódź region were enrolled. Patients were randomly assigned to receive ceftibuten, 400 mg once daily or other antibiotic on physician's choice with 2 or 3 times daily dosing. On the 5th day during the home visit the questionnaire study was performed and the compliance was measured by a pill count. Four hundred and six patients (205 in ceftibuten and 201 in other antibiotics group, respectively) were fully evaluable. Overall compliance was 76.6% with 97.6% for ceftibuten, 66.0% for antibiotics with b.i.d. dosing and 23.5% for antibiotics with t.i.d. dosing. Using a logistic regression analysis with a stepwise variable selection, dosing frequency was found to be a major variable associated with patient compliance (p = 0.00000, odds ratio 0.09, 95% confidence interval 0.057-0.165). Non-compliance with antibiotics is a common phenomenon in respiratory tract infections therapy. Once-daily antibiotic dosing leads to the best possible compliance in such circumstances. Due to its once-daily dosing and rare side effects, ceftibuten ensures nearly perfect compliance in respiratory tract infections therapy.
