Abstract
ackground: During the early phase of the COVID-19 pandemic, antibiotic usage among COVID-19 patients was
noted to be high in many countries. The objective of this study was to determine the prevalence of antibiotic usage
and factors afecting antibiotic usage among COVID-19 patients during the early phase of the COVID-19 pandemic in
Malaysia.
Methods: This was a cross-sectional study that involved reviewing medical records of COVID-19 Malaysian patients
aged 12 and above who were diagnosed with COVID-19 and received treatment in 18 COVID-19 hospitals from Febru‑
ary to April 2020. A minimum sample of 375 patients was required. A binary logistic regression analysis was performed
to determine factors associated with antibiotic usage. Variables with p<0.05 were considered statistically signifcant.
Results: A total of 4043 cases were included for analysis. The majority of the patients (87.6%) were non-smokers, male
(65.0%), and had at least one comorbidity (37.0%). The median age was 35 years (IQR: 38). The prevalence of antibi‑
otic usage was 17.1%, with 5.5% of them being prescribed with two or more types of antibiotics. The most frequent
antibiotics prescribed were amoxicillin/clavulanic acid (37.8%), ceftriaxone (12.3%), piperacillin/tazobactam (13.3%),
azithromycin (8.3%), and meropenem (7.0%). Male patients (adjusted OR 1.53), who had a comorbidity (adjusted OR
1.36), associated with more severe stage of COVID-19 (adjusted OR 6.50–37.06), out-of-normal range infammatory
blood parameters for neutrophils, lymphocytes, and C-reactive protein (adjusted OR 2.04–3.93), corticosteroid use
(adjusted OR 3.05), and ICU/HDU admission (adjusted OR 2.73) had higher odds of antibiotic use.
Conclusions: The prevalence of antibiotic usage in the early phase of the COVID-19 pandemic was low, with amoxi‑
cillin/clavulanic acid as the most common antibiotic of choice. The study showed that clinicians rationalized antibiotic
usage based on clinical assessment, supported by relevant laboratory parameters
