Antibiotic prescribing pattern of oral health practitioners before and during the COVID-19 pandemic at Wits Oral Health Centre.

ABSTRACT

The purpose of the study was to determine the antibiotic prescribing pattern of oral health practitioners before and during the Coronavirus disease 2019 (COVID-19) pandemic at Wits Oral Health Centre, South Africa. A retrospective, descriptive study was conducted using a systematic random sample of 698 records of patients who were prescribed antibiotics. The records were categorised into two groups pre-COVID-19 and COVID-19 pandemic periods. For each group, data collected and analysed included variables such as patient demographics, prescriber discipline, medical history, dental condition, dental procedure, type of antibiotic, dose, frequency, and duration. Most patients in both the pre-COVID-19 and COVID-19 groups (70.3% and 73%, respectively) were healthy. The most common indication for prescribing antibiotics was a painful tooth (58.7%). Amoxycillin and metronidazole remain the antibiotics of choice for most dental conditions. More patients were treated with antibiotics only in the COVID-19 group than the pre-COVID-19 group (46.8% vs 33.7%). A significant proportion of the prescribed antibiotics were not indicated in both the pre-COVID-19 and COVID-19 groups (53.1% and 54.3%, respectively). The increased antibiotic usage during the COVID-19 period, in spite of the decrease in the number of patients consulted, underscores the need for more strategies to be implemented to strengthen antimicrobial resistance surveillance and stewardship initiatives.
