Introduction: Antibiotic resistance is a global issue, with overprescribing and misuse of antimicrobials leading to the development of antibiotic resistant microorganisms. During this COVID pandemic, Aerosol Generating Procedures ( AGP) performed by dentists have been restricted to minimise potential transmission of the virus. This abstract reviews the effect of restricting AGP on the antimicrobial stewardship activity at the Oral Health Department at Star Health Group, a Community Health Service.
All antimicrobial prescribing is monitored monthly via the item code used .The audit would establish if the medication prescribed is in accordance to evidence based best practice as per the Therapeutic guidelines Oral and Dental . The number of prescriptions given per month was compared to the same month in the previous year as a percentage of the total number of adults seen for the various months.
Year/Month February March April May June July August September
Percentage of patients receiving antibiotics in 2020 6.27 3.16 14.44 7.91 11.48 2 7.66 7.58
Percentage of patients receiving antibiotics in 2019 7.23 6.34 5.31 5.23 5.1 1.8 2.53 3.24
Restrictions to (AGP) was put in place mid -March of 2020.
Even though the number of prescriptions given in the various months over the 2 years were not significantly different, the percentage of adult patients receiving prescriptions increased during the COVID pandemic. Most prescriptions were given as treatment could not be performed. For example ,50% of the prescription given in August 2020 were as a result of treatment being postponed till after restrictions eased when AGP could be performed.
Conclusion: Unfortunately, the pandemic has affected the antimicrobial stewardship activity. Prescriptions had to be prescribed over the treatment due to the restrictions in AGP.
