Discussion of A Mobile Phone Survey about Antibiotics Use during the COVID-19 Pandemic in Bangladesh
2. Discussion of A Mobile Phone Survey about Antibiotics Use during the COVID-19 Pandemic in Bangladesh
Our study found 32.7% (95% CI: 27.2–38.6) of the general population who reported illness in the preceding four weeks of the interview using antibiotics in the community. This proportion of antibiotic use for illnesses was higher than a pre-pandemic study in a community setting in Bangladesh during 2018, reporting (21%) antibiotics use within the last month
[18]. The COVID-19 pandemic may have influenced this rise in the proportion of antibiotic use in Bangladesh. However, the proportion of antibiotics used among COVID-19 patients was much low (12.5%) in our findings. However, determining the proportion of antibiotic use among COVID-19 cases was not the study’s objective. Yet, this study finding is much lower than 47% among the suspected COVID-19 cases reported in a previous hospital-based study from Bangladesh
[20]. The proportion of antibiotics used for COVID-19 respondents in our study is also much lower than the study conducted in Egypt during the COVID-19 pandemic
[17]. This may be likely to the fact that a very low number of COVID-19 cases were detected through this survey.
This study also measured the relevant knowledge regarding antibiotics irrespective of any respondents suffering from COVID-19 illness. The basic knowledge regarding antibiotics was very high among our survey respondents. Our study found a very high proportion (86.3%, 95% CI: 84.7–87.8) of respondents reported to know names of antibiotics compared with the previously reported proportion of 48% in Bangladesh before the COVID-19 pandemic
[18]. Furthermore, azithromycin, a macrolide antibiotic, was found as the most frequently (12%) recalled/reported antibiotic. This is perhaps because azithromycin was the most commonly prescribed antibiotics by physician’s advice and self-medication during the COVID-19 pandemic situation in Bangladesh
[32][27] and other countries in Europe and Asia
[33][28]. An online survey conducted at the end of March 2020 on 6227 physicians in 30 countries revealed that, after some common analgesics, azithromycin was the second-highest prescribed drug for COVID-19
[34][29]. Earlier reports on antibiotics awareness in Bangladesh stated the most frequent (11%) antibiotic reported to be a fluoroquinolone named ciprofloxacin
[35][30]. Although our study participants mentioned several unspecified harmful effects of antibiotics if taken without a physician’s prescription, very few (4%) could expressly state about antibiotic resistance. This rate is much lower than previous reports from Bangladesh, where 60% of the respondents stated antibiotic resistance
[35][30]. Overall, our findings illustrate that the general population was more knowledgeable about antibiotics during the COVID-19 pandemic compared with the pre-pandemic period.
Drug shops (pharmacies) contributed to the lion’s share (33.3%) of antibiotic dispensing without a prescription, and village doctors also contributed a handsome proportion (13.1%) in prescribing antibiotics in our study. Recent past studies in Bangladesh reported proportions as high as 43%
[36][31] and 16% from drug shops (pharmacies), and 18% from village doctors
[35][30]. Bangladesh’s common practice is to fetch over-the-counter medicines and even antibiotics regardless of consulting any qualified healthcare providers and the socio-economic status and education of the buyer
[37,38][32][33]. Our findings and this intrinsic nature of the population regarding procuring antibiotics raise a flag to immediately adopt and strengthen “prescription-only from formal providers” for antibiotic purchase
[20].
The antibiotic azithromycin was the most frequently prescribed/used, followed by cefixime—a third-generation cephalosporin. For treating suspected or confirmed mild-to-moderate COVID-19 cases without clinical suspicion of bacterial infections, antibiotics were discouraged from using for empirical treatment by WHO
[39][34]. However, due to overburdened laboratories for testing microbiological samples and lack of recommended antiviral therapy for COVID-19 infection, there was an increased empirical use of antimicrobials, including broad-spectrum antibiotics, by the clinicians
[13,40][13][35]. In Spain, a biphasic use of antibiotics was observed during the COVID-19 pandemic during 2020, along with amoxicillin/clavulanic acid and broad-spectrum antibiotics in public referral hospitals
[40][35]. Physicians reported the widespread use of broad-spectrum antibiotics in 23 countries
[9]. Moreover, the most common antibiotic classes prescribed were macrolides, fluoroquinolones, β-lactam/β-lactamase inhibitors, and cephalosporins in North America, Europe, China, and Asia
[33][28]. The use of macrolide and cephalosporins were similar to the results from a recent study conducted across Bangladesh during the first wave of the COVID-19 pandemic, where macrolide was the most frequently (27%) used antibiotic followed by cephalosporin (16%) among suspected COVID-19 patients before hospital admission
[20]. However, both azithromycin and cefixime belong to the Watch group antibiotic, which is not recommended according to the WHO AWaRe classification/tool
[41][36]. This non-compliance in antibiotic use also flags a concern for antimicrobial resistance.
Although we were able to cover respondents from across eight administrative divisions of Bangladesh, while interpreting our study findings, several limitations must be kept in consideration. The majority of our study respondents were males aged 18–40 years; therefore, our sampled respondents may not represent Bangladesh’s demographic profile. Furthermore, antibiotics were more likely to be used in extremes of age while we had no respondents <5 years, and only 4.2% were above 50 years. It was a survey based on mobile phone, and hence there may be recall bias in the responses leading to data loss and distortion. Furthermore, knowledge questions on antibiotics were limited to basic ones such as names, dosage, and harmful effects. Lastly, there were minimal opportunities to cross-validate responses, and only 5% of the complete interviews were randomly cross checked by repeat interviews. Overall, our results may be an underestimate of our actual prevalence of antibiotic use and knowledge.
In conclusion, our study findings underscored the increased proportion of antibiotic use for recent illnesses and raised knowledge about antibiotics at the community level during the COVID-19 pandemic in Bangladesh. Overuse of antibiotics, widespread availability, and generalized access to all types of antibiotics as over-the-counter drugs in the community surface raise concerns for antibiotic resistance in the near future. A robust monitoring system supported by policy and law is highly recommended to delimit over-the-counter antibiotic sales. Together with building community awareness on AMR, precisely due to the irrational use of antibiotics, it is imperative to promote, standardize, and strengthen antimicrobial stewardship within the health system of Bangladesh.
