Sales of antibiotics without a prescription in pharmacies, 2017 and 2021, China.

Objective: To measure sales of antibiotics without a prescription in pharmacies in China in 2017 and 2021, before and during the coronavirus disease 2019 (COVID-19) pandemic, and determine the factors associated with such sales.

Methods: We conducted cross-sectional surveys using the simulated patient method in retail pharmacies in 13 provinces in eastern, central and western China in 2017 and 2021. At the pharmacies, the simulated patients (trained medical students) reported that they had mild respiratory tract symptoms and asked for treatment, using a three-stage process: (i) request some treatment; (ii) request antibiotics; (iii) request specific antibiotics.
