Determining the impact of the COVID-19 pandemic on the consumption of antibiotics in Shaanxi province, China: an interrupted time-series analysis

Background

The COVID-19 pandemic, as well as associated prevention and control measures, have impacted the entire healthcare system, including the use patterns of medicine. However, the impact of COVID-19 on the use of antibiotics has not yet been extensively evaluated in China. This study aimed to evaluate the impact of the pandemic on the consumption and expenditure of antibiotics in public healthcare institutions in Shaanxi Province, China.

Methods

We used longitudinal data from the Shaanxi provincial drug procurement database in this study. An interrupted time-series analysis was performed to evaluate the effects of COVID-19 on consumption and expenditures of antibiotics in public healthcare institutions in Shaanxi from 1 January 2017 to 31 December 2020. Antibiotic consumption was expressed as the number of defined daily doses (DDDs) per 1,000 residents per day (DIDs), based on the population of Shaanxi Province at the end of each year from the National Bureau of Statistics. The pre-pandemic period was from January 2017 to January 2020, and the post-pandemic period was from February 2020 to December 2020.

Results

A declining trend in antibiotic consumption was observed immediately following the COVID-19 pandemic (β2 = -4.099; p < 0.001). Regarding the route of administration, a larger decrease in the consumption of oral antibiotics was observed compared to parenteral (β2 = -3.056; p < 0.001). The decrease in antibiotic consumption in the Watch category (β2 = -2.164; p < 0.001) was larger than in the Access category (β2 = -1.773; p < 0.001), and penicillins (J01C) (β2 = -1.261; p < 0.001) showed a higher decline than cephalosporins (J01D) (β2 = -1.147; p < 0.001). An increasing trend of broad-spectrum antibiotic consumption was observed after the onset of the pandemic (β3 = 0.021; p = 0.015). Expenditures on and consumption of antibiotics follow essentially the same trend.

Conclusion

Despite an initial decline in antibiotic consumption at the start of the COVID-19 pandemic, it had returned to prior levels by the end of 2020. Findings underscore the continued importance of antibiotic stewardship initiatives.

Long-term impact of COVID-19 pandemic on antibiotic use in primary care: lessons to optimize antimicrobial use

BACKGROUND

Lockdowns due to the COVID-19 pandemic was associated with changes in the pattern of use of antimicrobials, but persistence of changes after lockdowns has not been described. The objective was to describe the number of patients with dispensed antibiotic treatment and consumption of antibiotics in outpatients from primary care in Catalonia 18 months after the end of the emergency period.

RESEARCH DESIGN AND METHODS

Data for the COVID-19 pandemic period was obtained from March 2020 to December 2021. Four high transmission rate (Rt > 100) periods were established. To compare data, a simple Bayesian structural time series model was used.

RESULTS

The observed number of patients with dispensed antibiotics decreased respect to the estimated, especially during the four high transmission rate periods: April-May 2020 (lockdown period) (-42.57% and -42.68%); December 2020-February 2021 (-41.65%, -49.97% and -43.64%); October 2021 (-16.23%), and December 2021 (-20.16%). Overall antibiotic consumption was reduced by 23.37% (p = 0.002). These differences were mainly observed in those ≤ 15 years.

CONCLUSIONS

We describe the reduction in the number of patients with dispensed antibiotics and antibiotic consumption after the COVID-19 lockdown persisted in a period of recovery of healthcare accessibility. This information may help to improve antimicrobial use at the primary care level.

Use of antibiotics in Paediatric Primary Health Care before and during the COVID-19 pandemic

INTRODUCTION

Consumption of antibiotics is high in Spain, primarily in children. Excessive use of then contributes to the development of antimicrobial resistance. The aim of our study is to analyse the evolution of antibiotic consumption at the Primary Health Care in the paediatric population of Asturias, Spain, from 2014 to 2021, and to evaluate the impact of COVID-19 pandemic on it.

METHODS

Retrospective and observational study using data about antibacterial agents for systemic use dispensed for official prescriptions to children under 14 years in Primary Care. Antibiotic consumption is expressed as defined daily dose (DDD) per 1000 inhabitants per day (DID).

RESULTS

The antibiotic consumption rate dropped from 13.9 DID in 2014 to 4.0 in 2021 (β=-1,42, p=0,002), with and inflection point in 2019. From 2019 to 2020 antibiotic use dropped by 47.1%. Antibiotic consumption remained very low from April 2020 to September 2021, and then moderately increased from October 2021. Prevalence of antibiotic use dropped from 39.9% in 2014 to 17.5% in 2021 (β=-3,64, p=0,006). Relative consumption of amoxicillin/clavulanic acid decreased, while those of amoxiciline and third-generation cephalosporins increased.

CONCLUSIONS

Paediatric antibiotic consumption collapsed in Asturias in 2020, coinciding with COVID-19 pandemic. Monitoring of antimicrobial usage indicators will allow to check if these changes are sustained over time.

Trends and Patterns of Antibiotic Prescriptions in Primary Care Institutions in Southwest China, 2017-2022

Purpose

To explore the prescription patterns and usage trends of antibiotics within primary care institutions located in underdeveloped regions of China from 2017 to 2022.

Methods

A retrospective analysis of antibiotic prescriptions was conducted from 25 primary care institutions in Guizhou Province during the period of 2017-2022. Antibiotic prescriptions were categorized into appropriate and inappropriate use. Appropriate use is further categorized into preferred medication, and antibiotics can be used or substituted. Inappropriate use is further categorized into unnecessary use, incorrect spectrum of antibiotics and combined use of antibiotics. Factors associated with inappropriate use were investigated using generalized estimation equations. Holt-Winters and SARIMA models were employed to predict the number of inappropriate antibiotic prescriptions as the alternative model.

Results

A total of 941,924 prescriptions were included, revealing a decreasing trend in both the number and inappropriate rates of antibiotic prescriptions from 2017 to 2022. Diseases of the respiratory system (70.66%) was the most frequent target of antibiotic use, with acute upper respiratory infections of multiple and unspecified sites representing 52.04% of these cases. The most commonly used antibiotics were penicillins (64.44%). Among all prescriptions, inappropriate antibiotic prescriptions reached 66.19%. Physicians aged over 35, holding the title of associate chief physician and possessing more than 11 years of experience were more likely to prescribe antibiotics inappropriately. The phenomenon of inappropriate antibiotic use was commoner among children aged five or younger. By comparing model parameters, it was determined that the SARIMA model outperforms the Holt-Winters model in predicting the number of inappropriate antibiotic prescriptions among primary care institutions.

Conclusion

The number and inappropriate rates of antibiotic prescriptions in southwest China exhibited a downward trend from 2017 to 2022, but inappropriate prescription remains a serious problem in primary care institutions. Therefore, future efforts should focus on strengthening physician education, training, and clinical practice. Additionally, physicians' awareness of common misconceptions about inappropriate antibiotic use must be improved, and the prescribing behavior of physicians who fulfill patients' expectations by prescribing antibiotics needs to be modified.

Impact of COVID-19 pandemic on medication use in the older Italian population

OBJECTIVE

This study aims to analyse the impact of the pandemic on the amount of use and new medication dispensation for chronic diseases in the Italian population aged 65 years and older (almost 14 million inhabitants).

METHODS

The "Pharmaceutical Prescriptions database", which gathers data on medications, reimbursed by the National Health Service and dispensed by community pharmacies, was employed. Data were analysed as amount of use (defined daily dose-DDD per 1000 inhabitants); variation in DDD between 2020 and 2019 was calculated for the 30 categories with major consumption in 2020. Trends in prevalence and incidence of dispensations between 2020 and 2019 were calculated for four categories: antidiabetics, antihypertensives, antidepressants and drugs for respiratory diseases.

RESULTS

All medications showed a negative variation in DDD/1000 inhabitants between 2020 and 2019 except for anticoagulants (+ 5%). The percentage variation ranged from - 27.7% for antibiotics to - 6.4% for antipsychotics in 85 + year-old persons, but increased for most classes in the youngest (65-69 years). On the other hand, a decrease of the dispensation incidence of antidiabetics, antihypertensives, antidepressants and drugs for pulmonary disease was high, especially in the two extreme age groups, the youngest and the oldest one.

CONCLUSIONS AND RELEVANCE

Great variation in medication use between 2020 and 2019 was observed probably reflecting the low rate of infectious diseases due to the widespread use of protective devices and self-isolation, reduced healthcare access because of the lockdowns and the fear of going to hospital, and the reduction of screening and diagnostics due to health-care system overload.

Effect of the COVID-19 pandemic on antibiotic consumption: A systematic review comparing 2019 and 2020 data

Background

The coronavirus disease 2019 (COVID-19) pandemic has influenced antibiotic consumption over a long period, with variability in trends among studies. We conducted this systematic review to explore and compare the effect of the pandemic on overall and individual antibiotic consumption in 2020 with that in 2019.

Methods

This systematic literature review was conducted using PubMed, EMBASE, and Web of Science databases. Data on antibiotic consumption in Japan was sourced from the Japan Surveillance of Antimicrobial Consumption.

Results

A total of 1,442 articles and reports were screened, and 16 eligible articles were reviewed. The included studies were conducted in Jordan, Australia, Canada, UK, Japan, Brazil, India, China, and the EU. There was no study from African and Southeast Asian Countries. Overall, antibiotic consumption in the community consistently reduced in 2020. Studies from Australia, Canada, Portugal, Spain, the UK, Japan, and the European Union reported both decreases in overall and selected individual antibiotics consumption. In contrast, hospital-based studies reported both increases and decreases. Hospital-based studies in Lebanon, Spain, Italy, India, and the UK reported an increase in antibiotic consumption in 2020. Studies reporting an interruption of antibiotic stewardship programs during the pandemic also reported increases in antibiotic consumption for hospitalized patients in 2020 compared with that in 2019.

Conclusion

Our results showed a different trend between communities and hospitals in antibiotic consumption during 2020 compared to 2019. The continuity of the antibiotic stewardship program might have influenced the antibiotic consumption trend variability among hospitals in 2020. Alongside this, the lack of information on antibiotic consumption from low-income countries and limited reports from middle-income countries revealed gaps that need to be urgently filled.
