Community-level consumption of antibiotics according to the AWaRe (Access, Watch, Reserve) classification in rural Vietnam

Antibiotic use in public hospitals in Vietnam between 2018 and 2022: a retrospective study

OBJECTIVE

To assess the patterns of antibiotic consumption and expenditure in Vietnam.

DESIGN

This was a cross-sectional study.

SETTING

This study used data of antibiotic procurement that was publicly announced from 2018 to 2022 as a proxy for antibiotic consumption.

PARTICIPANTS

This study included winning bids from 390 procurement units in 63 provinces in Vietnam for 5 years with a total expenditure of US$ 12.8 billions that represented for approximately 20-30% of the national funds spend on medicines.

INTERVENTIONS

Antibiotics were classified by WHO AWaRe (Access, Watch and Reserve) classification.

OUTCOME MEASURES

The primary outcomes were the proportions of antibiotic consumptions in number of defined daily doses (DDD) and expenditures.

RESULTS

There was a total of 2.54 million DDDs of systemic antibiotics, which accounted for 24.7% (US $3.16 billions) of total expenditure for medicines purchased by these public health facilities. The overall proportion of Access group antibiotics ranges from 40.9% to 53.8% of the total antibiotic consumption over 5 years.

CONCLUSION

This analysis identifies an unmet target of at least 60% of the total antibiotic consumption being Access group antibiotics and an unreasonable share of expenditure for non-essential antibiotics in public hospitals in Vietnam.

Inappropriate antibiotic access practices at the community level in Eastern Ethiopia

Access to antibiotic medications is critical to achieving the Sustainable Development Goal for good health and well-being. However, non-prescribed and informal sources are implicated as the most common causes of inappropriate antibiotic access practices, resulting in untargeted therapy, which leads to antibiotic resistance. Hence, knowing antibiotic access practices at the community level is essential to target misuse sources. In this study, 2256 household representatives were surveyed between July and September 2023 to examine their antibiotic access practices. Of 1245 household members who received antibiotics, 45.6% did so inappropriately. Non-prescribed antibiotic access was more common among urban residents and individuals not enrolled in health insurance schemes. This means of antibiotic access was also more common among individuals concerned about distance, drug availability, and healthcare convenience at public facilities. In addition, women and rural individuals were more likely to get antibiotics from unauthorized sources. Unrestricted antibiotic dispensing practices in urban areas enabled their non-prescribed access, while unlicensed providers prevailed with this access practice in rural areas. In this regard, personal behaviors and healthcare-related gaps such as the lack of health insurance, inconvenience, and drug unavailability have led community members to seek antibiotics from unofficial and non-prescribed sources. Targeting the identified behavioral and institutional factors can enhance antibiotic access through prescriptions, hence reducing antibiotic resistance.

Health system barriers to the implementation of the national action plan to combat antimicrobial resistance in Vietnam: a scoping review

BACKGROUND

Vietnam is among 11 countries in the Western Pacific region that has developed a National Action Plan for Antimicrobial Resistance (NAPCA).

METHODS

This scoping review characterises health system barriers to the implementation of the Vietnam NAPCA, with reference to the WHO Health Systems Framework.

RESULTS

Over 7 years, between 2013 and 2020, the Ministry of Health (MOH) of Vietnam has been implementing activities to achieve the six NAPCA objectives. They include revision of regulations needed for antimicrobial resistance (AMR) prevention programs; formation and operation of national management bodies; improvement of antimicrobial stewardship (AMS) in hospitals; maintenance of surveillance systems for AMR; provision of trainings on AMR and antibiotics use to doctors and pharmacists; and organization of nation-wide educational campaigns. Limited cooperation between MOH management bodies, shortages of human resource at all health system levels, a low degree of agreement between national and hospital guidelines on antibiotic use, low capability in the domestic supply of standardised drugs, and unequal training opportunities for lower-level health professionals present ongoing challenges. Actions suggested for the next period of the NAPCA include a final review of what has been achieved by the plan so far and evaluating the effectiveness of the different components of the plan. Different options on how to improve coordination across sectors in the development of a new NAPCA should be put forward.

CONCLUSIONS

The 6-year implementation of the Vietnam NAPCA has yielded valuable lessons for AMS in Vietnam, guiding the development of future national plans, with a central focus on scaling up AMS in hospitals and promoting community AMS programs to combat AMR.

Availability of Access, Watch, and Reserve groups of essential antibiotics: a cross-sectional survey

Background

Lower-middle income countries face drastic challenges in Access to essential medicines. Data regarding Pakistan is scarce with no comprehensive study in this regard. The objectives of the study are to document and compare public and private sector availability of all essential antibiotics as well as to conduct a comparison among the AWaRe groups.

Methods

The study analyzed 103 essential antibiotics comprising 51 Access, 29 Watch, 6 Reserve, and 17 anti-tuberculosis drugs from 15th August to 10th September 2020 in Lahore, Pakistan. It included on-spot physical availability and availability trend surveys. The survey sites included five public tertiary care hospitals with one as anchor and four randomly selected. Their hospital pharmacies and one randomly selected private retail pharmacy from the vicinity each hospital comprised the ten sampling sites. Percentage availability for each antibiotic was categorized as high (>80%), fairly high (50-80%), low (30-<50%), very low (<30->0%), and not available (0%).

Results

The mean percentage on-spot availability was 23.76% ± 5.19 (14-25%) for public facilities and 59.20% ± 4.45 (54-66%) for private sector retail pharmacies. The overall percentage of available essential antibiotics varied significantly (p** < 0.001) in public and private sector sampling sites. Except for the Watch group, all other groups showed the mode of 0% availability. A significant difference (p**** < 0.00001) was seen in percentage availability by Access, Watch, Reserve, and anti-TB-all groups of essential antibiotics. The availability trend survey revealed a list of 18 medicines as 'as never been available', and five medicines were 'not available for 5 years or more than 5 years.' Fourteen medicines as 'never been heard.'

Conclusion

Non-availability of essential medicines is a significant public health challenge at public-sector facilities in Pakistan. It was observed that a number of essential antibiotics were not available in both public and private sectors. A number of corrective strategies are required. This includes the engagement of stakeholder and government bodies. This can help to improve supply chain barriers.

Community Antibiotic Consumption in Cyprus for the Period 2015 to 2022

BACKGROUND

Cyprus currently reports to ESAC-Net the total consumption of antimicrobials, without distinguishing between hospital and community-based antibiotic use. As a result, these data can only provide generalized insights into antimicrobial trends in the country.

AIM

This study is a first attempt to retrospectively analyze community antibiotic consumption in Cyprus for the period of 2015 to 2022.

MATERIAL AND METHODS

Data on community antimicrobial consumption between 2015 and 2022 were extracted from Pharmatrack's database. Orally administered dispensed antibiotics were categorized under the J01 group of the WHO Anatomical Therapeutic Chemical (ATC) classification and by the WHO's AWaRe classification of antibiotics. Antibiotic consumption was calculated in both packages consumed and per 1000 inhabitants, overall, by year of consumption and districts.

RESULTS

During the period of 2015-2022, there was variability in the mean outpatient antibiotic consumption per 1000 inhabitants among the five districts in Cyprus. Community consumption increased by 38% throughout the study period. Additionally, a decrease of 3% in the consumption of WHO 'Access' antibiotics was observed, accompanied with a concurrent increase of 3% in the 'Watch' group. Specifically, in 2022 the WHO 'Access' group consumption in the Cypriot community was 48%, significantly lower than the WHO's goal of 60% and the EU's goal of 70% for 'Access' antibiotic consumption.

CONCLUSIONS

Antibiotic consumption in the community of Cyprus between 2015 and 2022 demonstrated substantial variability among districts, with higher consumption in less populated areas. There was an increasing trend in community consumption over the years and a decreasing trend in the percentage of 'Access' antibiotics prescribed.

Assessment of antimicrobial drugs employed at government-operated hospitals in central and northern provinces of Iraq

OBJECTIVE

Aim: To document the clinical patterns of antibiotic prescriptions in government hospitals, where the majority of physicians possess a degree-based training.

PATIENTS AND METHODS

Materials and Methods: A Retrospective cross section study carried out between 1/7/2022 and April 2023 that enrolling 300 patients from governmental hospitals from different provinces of Central and northern Iraq. The research form contained 15 fields divided into three sections. The first section contains social information such as age, gender, field of work, Residence and education. The second part consists of diagnosis and lab. Finding. The third part related to antibiotic uses: Number of AB prescribed, duration of using, type of use, route of administration, AB interaction, dose administration of AB, indication of Ab, and Class of AB.

RESULTS

Results: A total of 300 eligible patients, 165 patients (55.0%) were male and 135 (45.0%) were female, patients were <20 years ages were 117 (39.0%), 25 (8.3%) from the 20-29 years age group, 40-49 years ages were 28 (9.3%) and >50 years ages were 105 (35.0%) were which belong to the pediatric population. The 198 patients (66.0%) were used cephalosporins and 106 (53.5%) of them used alone. A 13-19% percentage of patients had used penicillin, carbapenem, anti-fungal, and aminoglycoside in combination form.

CONCLUSION

Conclusions: The implementation of clinical guidelines, the provision of direct instruction, and the regular dissemination of antibiogram data have the potential to encourage a more judicious consumption of antibiotics.

Evaluation of the impact before and after the application of an antimicrobial stewardship program at Dong Thap General Hospital, Vietnam, from 2017 to 2021

Background

Vietnam has one of the highest rates of antibiotic resistance in Asia. In 2020, the Vietnam Minister of Health introduced new legislation for the implementation of an antimicrobial stewardship program (ASP). The evidence for the effectiveness of ASP in small hospitals and hospitals located in provinces was limited compared with larger-scale and central city hospitals.

Aim

Evaluation of the impact before and after the introduction of an antimicrobial stewardship program at Dong Thap General Hospital, from 2017 to 2021.

Methods

Retrospective data was collected from June 2017 to June 2021. The impact of the ASP on changes in antibiotic use and the clinical outcome associated with the implementation of the ASP was evaluated using autoregressive integrated moving average modelling of controlled interrupted time-series analysis.

Results

There was a significant and sustained decrease in antibiotic consumption level (step change) in 2 indicators, DOT/1000PD (129.55; P<0.01) and LOT/1000PD (99.95, P<0.01), immediately after the ASP intervention. There were no statistically significant changes identified in terms of consumption with DDD/1000PD, or in the clinical outcomes. The results showed no statistically significant change in consumption trend (ramps) in all evaluated indicators. No statistically significant changes in consumption levels and trends were observed in the control group.

Conclusion

The ASP implemented in Dong Thap General Hospital from 2017 to 2021 showed a considerable influence on antibiotic consumption as indicated by the DOT/1000 PD and LOT/1000 PD during the initial stages. Moreover, controlling antibiotic consumption did not negatively impact patient outcomes.

A Narrative Review of Antibiotic Prescribing Practices in Primary Care Settings in South Africa and Potential Ways Forward to Reduce Antimicrobial Resistance

There are concerns with the current prescribing of antibiotics in both the private and public primary care settings in South Africa. These concerns need to be addressed going forward to reduce rising antimicrobial resistance (AMR) rates in South Africa. Concerns include adherence to current prescribing guidelines. Consequently, there is a need to comprehensively summarise current antibiotic utilization patterns from published studies as well as potential activities to improve prescribing, including indicators and antimicrobial stewardship programs (ASPs). Published studies showed that there was an appreciable prescribing of antibiotics for patients with acute respiratory infections, i.e., 52.9% to 78% or more across the sectors. However, this was not universal, with appreciable adherence to prescribing guidelines in community health centres. Encouragingly, the majority of antibiotics prescribed, albeit often inappropriately, were from the 'Access' group of antibiotics in the AWaRe (Access/Watch/Reserve) classification rather than 'Watch' antibiotics to limit AMR. Inappropriate prescribing of antibiotics in primary care is not helped by concerns with current knowledge regarding antibiotics, AMR and ASPs among prescribers and patients in primary care. This needs to be addressed going forward. However, studies have shown it is crucial for prescribers to use a language that patients understand when discussing key aspects to enhance appropriate antibiotic use. Recommended activities for the future include improved education for all groups as well as regularly monitoring prescribing against agreed-upon guidelines and indicators.

Antibiotic resistance and heteroresistance in Helicobacter pylori isolates from symptomatic Vietnamese children: A prospective multicenter study

BACKGROUND

Antibiotic resistance of Helicobacter pylori (H. pylori) is increasing worldwide, with geographical variations, impacting the treatment outcomes. This study assessed the antibiotic resistance patterns of H. pylori in Vietnamese children.

MATERIALS AND METHODS

Symptomatic children undergoing gastroduodenoscopy at two tertiary Children's Hospitals in Ho Chi Minh City were recruited. Antral and corpus biopsies were obtained and cultured separately. Susceptibility to amoxicillin (AMO), clarithromycin (CLA), metronidazole (MET), levofloxacin (LEV), and tetracycline (TET) was determined using E-test. Polymerase chain reaction was performed on another antral biopsy to detect the urease gene, cytotoxin-associated gene A (cagA), vacuolating cytotoxin A (vacA) genotypes, and 23S rRNA mutations conferring CLA resistance.

RESULTS

Among 123 enrolled children, a high primary resistance rate was found for CLA (68.5%, 61/89), followed by LEV (55.1%), MET (31.5%), AMO (25.8%), and TET (1.1%). Secondary resistance rates were 82.1% (7/28), 71.4%, 53.6%, and 3.6% for CLA, LEV, MET, and TET, respectively. Multidrug resistance was frequent (67.7%), with common patterns including CLA + LEV (20.3%) and CLA + MTZ + LEV (15.2%). Heteroresistance was detected in eight children (6.5%). The A2143G mutation was detected in 97.5% (119/122) of children. 86.1% of children had positive cagA strains and 27.9% had multiple vacA genotypes. No factor was significantly associated with antibiotic resistance.

CONCLUSIONS

The alarming rate of antibiotic resistance for H. pylori, especially for CLA, with emerging multi- and hetero-resistant strains, pose a major treatment challenge that precludes CLA use as empirical therapy. Biopsies from both antrum and corpus can improve H. pylori culture, allowing tailored treatment based on antimicrobial susceptibility.

An Evaluation of the Impact of Increasing the Awareness of the WHO Access, Watch, and Reserve (AWaRe) Antibiotics Classification on Knowledge, Attitudes, and Hospital Antibiotic Prescribing Practices

The study aims to determine the effect of enhancing knowledge and awareness of the WHO Access, Watch, and Reserve (AWaRe) antibiotics classification on hospital clinical staff's knowledge, attitudes and antibiotic prescribing practices. A pre-post-intervention study design was employed. The intervention was an educational activity that involved teaching physicians and pharmacists about the AWaRe classification and the risk of antibiotic resistance. A questionnaire was administered to clinical staff pre-and post-intervention. In the pre-interventional stage, 78.5% of participants stated they had not heard about the AWaRe classification of antibiotics. After receiving the intervention: the knowledge regarding the meaning and purpose of AWaRe classification of antibiotics increased from 39.1% to 75.4%; the percentage of participants who agreed with following the AWaRe classification of antibiotics in their practice increased from 21.7% to 58.5%; and the percentage of participants who agreed that AWaRe classification of antibiotics can suggest safe choices of antibiotics increased from 56.5% to 90.8%. Hospital antibiotic use of the Access group increased by 6.6% from pre- to post-intervention. The use of the Watch group and Reserve group decreased post-intervention by 1.7%, and 43.1%, respectively. This study showed important gaps in knowledge and attitudes towards AWaRe, highlighting the need for increasing the awareness of the AWaRe tool amongst healthcare practitioners to ensure rational use of antibiotics.

Assessment of antibiotic prescribing patterns at dental and primary health care clinics according to WHO Access, Watch, Reserve (AWaRe) classification

BACKGROUND

The 2019 WHO Access, Watch, Reserve (AWaRe) antibiotic classification framework aims to prevent irrational prescribing of antibiotics used to treat widespread infections. This study explored antibiotic prescribing pattern for appropriate indications by family physicians and general dentists in primary health care practices.

METHODS

A retrospective review of patients' electronic medical records was conducted over 6 months, from May 1, 2020, to November 30, 2020. The data were collected from 24 general family medicine and dental practices within the North West Armed Forces in Tabuk city. Antibiotic prescribing for systemic use (J01) was assessed by the number of prescriptions and the number defined daily doses (DDDs) and then analyzed according to the AWaRe classification. The prescribing of antibiotics for appropriate indications was assessed through comparing the prescription pattern with the recently published and relevant clinical guidelines. Multivariate logistic regression analysis was used to predict the association between the prescribing of AWaRe category and some demographic and disease-related factors.

RESULTS

In total, 752 prescriptions of antibiotics were collected. Watch-group antibiotics such as second-generation cephalosporin and macrolides were more likely prescribed (51.1%) based on the number of prescriptions and (52.2%) based on DDDs compared with Access-group antibiotics (48.9%) and (47.8%), respectively. The percentages of Watch group antibiotics for children and adults were 66.7% and 42.9%, respectively. Adherence to prescribing guidelines was poor for children (27.2%) and adults (64%). Being a child (adjusted odds ratio [OR]: 2.89; 95% confidence interval [CI] = 1.46-5.78), diagnosis with acute respiratory tract infection (adjusted OR, 2.62; 95% CI = 1.03-6.69), and urinary tract infection (adjusted OR, 4.69; 95% CI = 2.09-10.56) were associated with higher prescriptions of Watch-group antibiotics.

CONCLUSIONS

a higher prescribing of Watch-group antibiotics and poor adherence to antibiotic guidelines were observed, especially for children. The findings of this study identified targets for further improvement and interventions needed to develop better antibiotic-prescribing practices.

Moderate and transient impact of antibiotic use on the gut microbiota in a rural Vietnamese cohort

The human gut microbiota has been shown to be significantly perturbed by antibiotic use, while recovering to the pre-treatment state several weeks after short antibiotic exposure. The effects of antibiotics on the gut microbiota have however been mainly documented in high-income settings with lower levels of antibiotic resistance as compared to lower and middle income countries (LMIC). This study aimed to examine the long-term consequences of repeated exposure to commonly use antibiotics on the fecal microbiota of residents living in a low income setting with high prevalence of antibiotic resistance. Fecal samples from household individuals (n = 63) participating in a rural cohort in northern Vietnam were collected monthly for a period of 6 months. Using 16S V4 rRNA gene region amplicon sequencing and linear mixed-effects models analysis, we observed only a minor and transient effect of antibiotics on the microbial richness (ß = - 31.3, 95%CI = - 55.3, - 7.3, p = 0.011), while the microbial diversity was even less affected (ß = - 0.298, 95%CI - 0.686, 0.090, p = 0.132). Principal Component Analyses (PCA) did not reveal separation of samples into distinct microbiota-based clusters by antibiotics use, suggesting the microbiota composition was not affected by the antibiotics commonly used in this population. Additionally, the fecal microbial diversity of the subjects in our study cohort was lower when compared to that of healthy Dutch adults (median 3.95 (IQR 3.72-4.13) vs median 3.69 (IQR3.31-4.11), p = 0.028, despite the higher dietary fiber content in the Vietnamese as compared to western diet. Our findings support the hypothesis that frequent antibiotic exposure may push the microbiota to a different steady state that is less diverse but more resilient to disruption by subsequent antibiotic use.

Non-prescribed antibiotic use for children at community levels in low- and middle-income countries: a systematic review and meta-analysis

BACKGROUND

Non-prescribed antibiotic use is an emerging risky practice around the globe. An inappropriate use involving nonprescription access is one cause of the rapid increase in antibiotic resistance. Children commonly encounter many self-limiting illnesses for which they frequently use antibiotics without prescription. However, no specific and conclusive evidence exists to inform actions against this unsafe practice. We thus aimed to estimate the pooled proportion of non-prescribed antibiotic use for children at community levels in low- and middle-income countries.

METHODS

A systematic search of records was conducted from PubMed/Medline, Embase, Scopus, CINAHL, and Google scholar. Eligible English-language publications were original articles which reported on community-based non-prescribed antibiotic use for children and conducted in low- and middle-income countries. Study features and the number of antibiotics used without prescriptions were extracted and pooled for effect sizes employing a random-effects model. The pooled proportion of non-prescribed antibiotic use was estimated as a percentage.

RESULTS

In this analysis, we included a total of 39 articles consisting of 40,450 participants. Of these, 16,315 participants used non-prescribed antibiotics. The pooled percentage for this use of non-prescribed antibiotics was 45% (95% CI: 40-50%). The estimate was considerably higher in studies involving simulated patient methods (56%; 95% CI: 49-62%) than those studies with community surveys (40%; 95% CI: 34-46%) (P = 0.001). It was also varied by the recall period of antibiotics use-56% (95% CI: 50-62%) for instantly observed practice, 36% (95% CI: 22-50%) for within two week recall, 35% (95% CI: 26-45%) for 1-6 months recall, and 46% (95% CI: 37-54%) for more than six months recall (P = 0.001). Primary access points for the non-prescribed antibiotic uses were retail drug outlets.

CONCLUSIONS

We found that nearly half of the antibiotics used for children in community settings were without prescriptions. For these unsafe practices, caregivers accessed antibiotics mainly from drug outlets. Hence, context-specific educational and regulatory interventions at these outlets and the community levels are the first steps to improving antibiotic usage for children in low- and middle-income countries.

Country data on AMR in Vietnam in the context of community-acquired respiratory tract infections: links between antibiotic susceptibility, local and international antibiotic prescribing guidelines, access to medicines and clinical outcome

BACKGROUND

Antimicrobial resistance (AMR) is one of the biggest threats to global public health. Selection of resistant bacteria is driven by inappropriate use of antibiotics, amongst other factors. COVID-19 may have exacerbated AMR due to unnecessary antibiotic prescribing. Country-level knowledge is needed to understand options for action.

OBJECTIVES

To review the current situation with respect to AMR in Vietnam and initiatives addressing it. Identifying areas where more information is required will provide a call to action to minimize any further rises in AMR within Vietnam and improve patient outcomes.

METHODS

National initiatives to address AMR in Vietnam, antibiotic use and prescribing, and availability of susceptibility data, in particular for the key community-acquired respiratory tract infection (CA-RTI) pathogens Streptococcus pneumoniae and Haemophilus influenzae, were identified. National and international antibiotic prescribing guidelines for CA-RTIs (community-acquired pneumonia, acute otitis media and acute bacterial rhinosinusitis) commonly used locally were also reviewed, plus local antibiotic availability. Insights from clinicians in Vietnam were sought to contextualize this information.

CONCLUSIONS

In Vietnam there have been some initiatives addressing AMR; Vietnam was the first country in the Western Pacific Region to develop a national action plan to combat AMR, which according to the WHO is being implemented. Vietnam also has one of the highest rates of AMR in Asia due, in part, to the overuse of antimicrobial drugs, both in the animal health sector and in humans in both hospitals and the community. In addition, despite a 2005 law requiring antibiotic prescription, there is unrestricted access to over-the-counter antibiotics. Several global surveillance studies provide antibiotic susceptibility data for CA-RTI pathogens in Vietnam including Survey of Antibiotic Resistance (SOAR) and SENTRY (small isolate numbers only). For management of the common CA-RTIs in Vietnam there are several country-specific local antibiotic prescribing guidelines and in addition, there is a range of international guidelines referred to, but these may have been created based on pathogen resistance patterns that might be very different to those in Vietnam. Expert clinician opinion confirms the high resistance rates among common respiratory pathogens. A more standardized inclusive approach in developing local guidelines, using up-to-date surveillance data of isolates from community-acquired infections in Vietnam, could make management guideline use more locally relevant for clinicians. This would pave the way for a higher level of appropriate antibiotic prescribing and improved adherence. This would, in turn, potentially limit AMR development and improve clinical outcomes for patients.

A National Survey of Dispensing Practice and Customer Knowledge on Antibiotic Use in Vietnam and the Implications

Misconceptions and pressures have increased the sales of antibiotics without a prescription across countries. There are concerns with such practices in Vietnam given rising antimicrobial resistance rates. A national survey was conducted among 360 private drugstores located in nine provinces in Vietnam. Anonymous interviews were conducted with participants selected by convenience sampling. Subsequently, multivariable logistic regression analyses were undertaken evaluating the relationship between customer characteristics and antibiotic purchases. A total of 480 out of 1626 surveyed participants purchased antibiotics, 81.7% of which did not have a prescription, involving 29 different antibiotics. In 86.4% of these, participants were prescribed antibiotics by drug sellers. Most antibiotics were sold to treat respiratory tract infections (61.4%), with the ‘Access’ antibiotics (amoxicillin and cephalexin) being the most frequently sold. Only one-fifth of participants understood that they were breaking the law by purchasing antibiotics without a prescription. Participants purchasing antibiotics without a prescription had lower awareness concerning antibiotic laws and treatment duration (p < 0.05). Under 50% agreed to having a doctors’ prescription in the future when purchasing antibiotics. Freelancer occupation (OR = 0.52, 95% CI = 0.83−0.96) and a lower educational level (OR = 0.49, 95% CI = 0.25−0.96) were factors related to purchasing antibiotics without a prescription. Overall, we recommend increasing fines and monitoring of drugs stores, greater promotion of the family doctor system as well as increasing media and educational campaigns to limit self-purchasing of antibiotics in Vietnam and reduce resistance.

Transmission of gram-negative antibiotic-resistant bacteria following differing exposure to antibiotic-resistance reservoirs in a rural community: a modelling study for bloodstream infections

Exposure to community reservoirs of gram-negative antibiotic-resistant bacteria (GN-ARB) genes poses substantial health risks to individuals, complicating potential infections. Transmission networks and population dynamics remain unclear, particularly in resource-poor communities. We use a dynamic compartment model to assess GN-ARB transmission quantitatively, including the susceptible, colonised, infected, and removed populations at the community-hospital interface. We used two side streams to distinguish between individuals at high- and low-risk exposure to community ARB reservoirs. The model was calibrated using data from a cross-sectional cohort study (N = 357) in Chile and supplemented by existing literature. Most individuals acquired ARB from the community reservoirs (98%) rather than the hospital. High exposure to GN-ARB reservoirs was associated with 17% and 16% greater prevalence for GN-ARB carriage in the hospital and community settings, respectively. The higher exposure has led to 16% more infections and attributed mortality. Our results highlight the need for early-stage identification and testing capability of bloodstream infections caused by GN-ARB through a faster response at the community level, where most GN-ARB are likely to be acquired. Increasing treatment rates for individuals colonised or infected by GN-ARB and controlling the exposure to antibiotic consumption and GN-ARB reservoirs, is crucial to curve GN-ABR transmission.

Reliability and validity evaluation of the appropriate antibiotic use self-efficacy scale for Chinese adults

BACKGROUND

Antibiotic resistance is one of the greatest threats to global public health. Inappropriate use of antibiotics can lead to an increase in antibiotic resistance. Individual self-efficacy in the appropriate use of antibiotics plays a key role, especially in China where the population has easy access to antibiotics. However, there are no tools available to assess the self-efficacy of appropriate antibiotic use for Chinese adults. We aimed to translate and develop a Chinese version of the Appropriate Antibiotic Use Self-Efficacy Scale (AAUSES), and validate its reliability and validity.

METHODS

A total of 659 adults were recruited to participate in the questionnaire. The original version scale was first translated into Chinese using the backward and forward translation procedures. The internal consistency reliability of the scale was measured by the Cronbach alpha coefficient, the test-retest reliability, and the corrected item-total correlation. The validity of the scale was assessed by the content validity index, exploratory factor analysis, and confirmatory factor analysis.

RESULTS

The content validity index of the scale was 0.96. Exploratory factor analysis (EFA) supported a 4-factor structure of the translated questionnaire, and the discriminant validity of the scale was good. Confirmatory factor analysis (CFA) showed in the model fitness index, the chi-square degree of freedom was 2.940, the goodness-of-fit index(GFI) was 0.929, the incremental fit index (IFI) was 0.908, the comparative fit index(CFI) was 0.906, root mean square error of approximation(RMSEA) was 0.077, and standardized root mean residual (SRMR) was 0.0689, and the model fitting indexes were all in the acceptable range. Cronbach alpha coefficient for the scale was 0.910. The test-retest reliability was 0.947, and the corrected item-total correlations for the items ranged from 0.488 to 0.736. Self-efficacy for appropriate antibiotic use in adults varied by education, occupation, income, place of residence, and whether or not they had heard of antibiotic resistance.

CONCLUSIONS

The results indicated that the Chinese version of the AAUSES had good reliability and validity. Therefore, it can be considered a tool to evaluate the appropriate antibiotic use self-efficacy of adults in China.

Access-Watch ratio based on access, watch, and reserve classification of antibiotics in public health facilities of Tamil Nadu

The rise in cases of antibiotic resistance can be mainly attributed to the overuse and misuse of antibiotics. To address this issue, the WHO launched Access, Watch, and Reserve (AWaRe) classification of antibiotics in 2017 as a surveillance tool. Many countries have adopted it to monitor and optimize their antibiotic usage. However, implementation of it is yet not seen at a very appreciable level. Through this survey, we tried to explore the prescribing pattern of antibiotics based on the WHO AWaRe classification in selected secondary and tertiary care health facilities of Tamil Nadu. In-patient case sheets were audited in selected departments across 18 health facilities in six districts. Proportionately higher use of the watch group of antibiotics was found in all the districts. A lower access-watch ratio suggests the need for judicious implementation of such tools to safeguard this life-saving good and ensuring its sustainability.

Pattern of Antibiotic Use among Hospitalized Patients according to WHO Access, Watch, Reserve (AWaRe) Classification: Findings from a Point Prevalence Survey in Bangladesh

For supporting antibiotic stewardship interventions, the World Health Organization (WHO) classified antibiotics through the AWaRe (Access, Watch, and Reserve) classification. Inappropriate use of antimicrobials among hospital-admitted patients exposes them to the vulnerability of developing resistant organisms which are difficult to treat. We aimed to describe the proportion of antibiotic use based on the WHO AWaRe classification in tertiary and secondary level hospitals in Bangladesh. A point prevalence survey (PPS) was conducted adapting the WHO PPS design in inpatients departments in 2021. Among the 1417 enrolled patients, 52% were female and 63% were from the 15–64 years age group. Nearly 78% of patients received at least one antibiotic during the survey period. Third-generation cephalosporins (44.6%), penicillins (12.3%), imidazoles (11.8%), aminoglycosides (7.2%), and macrolides (5.8%) were documented as highly used antibiotics. Overall, 64.0% of Watch, 35.6% of Access, and 0.1% of Reserve group antibiotics were used for treatment. The use of Watch group antibiotics was high in medicine wards (78.7%) and overall high use of Watch antibiotics was observed at secondary hospitals (71.5%) compared to tertiary hospitals (60.2%) (p-value of 0.000). Our PPS findings underscore the need for an urgent nationwide antibiotic stewardship program for physicians including the development and implementation of local guidelines and in-service training on antibiotic use.

Antibiotic Use before, during, and after Seeking Care for Acute Febrile Illness at a Hospital Outpatient Department: A Cross-Sectional Study from Rural India

Antibiotic resistance is a naturally occurring phenomenon, but the misuse and overuse of antibiotics is accelerating the process. This study aimed to quantify and compare antibiotic use before, during, and after seeking outpatient care for acute febrile illness in Ujjain, India. Data were collected through interviews with patients/patient attendants. The prevalence and choice of antibiotics is described by the WHO AWaRe categories and Anatomical Therapeutic Chemical classes, comparing between age groups. Units of measurement include courses, encounters, and Defined Daily Doses (DDDs). The antibiotic prescription during the outpatient visit was also described in relation to the patients’ presumptive diagnosis. Of 1000 included patients, 31.1% (n = 311) received one antibiotic course, 8.1% (n = 81) two, 1.3% (n = 13) three, 0.4% (n = 4) four, 0.1% (n = 1) five, and the remaining 59.0% (n = 590) received no antibiotics. The leading contributors to the total antibiotic volume in the DDDs were macrolides (30.3%), combinations of penicillins, including β-lactamase inhibitors (18.8%), tetracyclines (14.8%), fluoroquinolones (14.6%), and third-generation cephalosporins (13.7%). ‘Watch’ antibiotics accounted for 72.3%, 52.7%, and 64.0% of encounters before, during, and after the outpatient visit, respectively. Acute viral illness accounted for almost half of the total DDDs at the outpatient visit (642.1/1425.3, 45.1%), for which the macrolide antibiotic azithromycin was the most frequently prescribed antibiotic (261.3/642.1, 40.7%).

Availability, Prices and Affordability of Antibiotics Stocked by Informal Providers in Rural India: A Cross-Sectional Survey

Providers without formal training deliver healthcare and antibiotics across rural India, but little is known about the antibiotics that they stock. We conducted a cross-sectional survey of such informal providers (IPs) in two districts of West Bengal, and assessed the availability of the antibiotics, as well as their sales volumes, retail prices, percentage markups for IPs and affordability. Of the 196 IPs that stocked antibiotics, 85% stocked tablets, 74% stocked syrups/suspensions/drops and 18% stocked injections. Across all the IPs, 42 antibiotic active ingredients were stocked, which comprised 278 branded generics from 74 manufacturers. The top five active ingredients that were stocked were amoxicillin potassium clavulanate (52% of the IPs), cefixime (39%), amoxicillin (33%), azithromycin (25%) and ciprofloxacin (21%). By the WHO's AWaRe classification, 71% of the IPs stocked an ACCESS antibiotic and 84% stocked a WATCH antibiotic. The median prices were in line with the government ceiling prices, but with substantial variation between the lowest and highest priced brands. The most affordable among the top five tablets were ciprofloxacin, azithromycin, cefixime and amoxicillin (US$ 0.8, 0.9, 1.9 and 1.9 per course), and the most affordable among the syrups/suspensions/drops were azithromycin and ofloxacin (US$ 1.7 and 4.5 per course, respectively), which are mostly WATCH antibiotics. IPs are a key source of healthcare and antibiotics in rural communities; practical interventions that target IPs need to balance restricting WATCH antibiotics and expanding the basket of affordable ACCESS antibiotics.

Antibiotic Use in Suspected and Confirmed COVID-19 Patients Admitted to Health Facilities in Sierra Leone in 2020-2021: Practice Does Not Follow Policy

Inappropriate use of antibiotics during the COVID-19 pandemic has the potential to increase the burden of antimicrobial resistance. In this study, we report on the prevalence of antibiotic use and its associated factors among suspected and confirmed COVID-19 patients admitted to 35 health facilities in Sierra Leone from March 2020-March 2021. This was a cross-sectional study using routinely collected patient data. Of 700 confirmed COVID-19 patients, 47% received antibiotics. The majority (73%) of the antibiotics belonged to the 'WATCH' group of antibiotics, which are highly toxic and prone to resistance. The most frequently prescribed antibiotics were azithromycin, ceftriaxone, amoxicillin, metronidazole, and amoxicillin-clavulanic acid. Antibiotic use was significantly higher in patients aged 25-34 years than in those with severe disease. Of 755 suspected COVID-19 patients, 61% received antibiotics, of which the majority (58%) belonged to the 'WATCH' category. The most frequently prescribed antibiotics were ceftriaxone, metronidazole, azithromycin, ciprofloxacin, and amoxycillin. The prevalence of antibiotic use among suspected and confirmed COVID-19 patients admitted to healthcare facilities in Sierra Leone was high and not in line with national and WHO case management guidelines. Training of health care providers, strengthening of antimicrobial stewardship programs, and microbiological laboratory capacity are urgently needed.

Emergence of amoxicillin resistance and identification of novel mutations of the pbp1A gene in Helicobacter pylori in Vietnam

Background

Amoxicillin-resistant Helicobacter pylori (H. pylori) strains seem to have increased over time in Vietnam. This threatens the effectiveness of H. pylori eradication therapies with this antibiotic. This study aimed to investigate the prevalence of primary resistance of H. pylori to amoxicillin and to assess its association with pbp1A point mutations in Vietnamese patients.

Materials and methods

Naive patients who presented with dyspepsia undergoing upper gastrointestinal endoscopy were recruited. Rapid urease tests and PCR assays were used to diagnose H. pylori infection. Amoxicillin susceptibility was examined by E-tests. Molecular detection of the mutant pbp1A gene conferring amoxicillin resistance was carried out by real-time PCR followed by direct sequencing of the PCR products. Phylogenetic analyses were performed using the Tamura-Nei genetic distance model and the neighbor-joining tree building method.

Results

There were 308 patients (46.1% men and 53.9% women, p = 0.190) with H. pylori infection. The mean age of the patients was 40.5 ± 11.4 years, ranging from 18 to 74 years old. The E-test was used to determine the susceptibility to amoxicillin (minimum inhibitory concentration (MIC) ≤ 0.125 μg/ml) in 101 isolates, among which the rate of primarily resistant strains to amoxicillin was 25.7%. Then, 270 sequences of pbp1A gene fragments were analysed. There were 77 amino acid substitution positions investigated, spanning amino acids 310–596, with the proportion varying from 0.4 to 100%. Seven amino acid changes were significantly different between amoxicillin-sensitive (Amox^S) and amoxicillin-resistant (Amox^R) samples, including Phe₃₆₆ to Leu (p <  0.001), Ser₄₁₄ to Arg (p <  0.001), Glu/Asn_464–465 (p = 0.009), Val₄₆₉ to Met (p = 0.021), Phe₄₇₃ to Val (p <  0.001), Asp₄₇₉ to Glu (p = 0.044), and Ser/Ala/Gly_595–596 (p = 0.001). Phylogenetic analyses suggested that other molecular mechanisms might contribute to amoxicillin resistance in H. pylori in addition to the alterations in PBP1A.

Conclusions

We reported the emergence of amoxicillin-resistant Helicobacter pylori strains in Vietnam and new mutations statistically associated with this antimicrobial resistance. Additional studies are necessary to identify the mechanisms contributing to this resistance in Vietnam.

Vigilance Needed in Treating Leprosy Patients in Accordance with WHO's AWaRe

BACKGROUND

Leprosy is a highly stigmatized disease that can range from a minor skin lesion to life-threatening conditions such as deformities and disability. The World Health Organization (WHO) has developed a tool called "Access, Watch, and Reserve" (AWaRe) to reduce antibiotic misuse and abuse.

AIM

The purpose of this review is to determine whether the drugs used in the leprosy treatment regimen are complied with the AWaRe programme, in order to improve the quality of hospital antibiotic use and reduce the incidence of antimicrobial resistance (AMR).

METHODS

We started by looking for antibiotics that are used in the treatment and chemoprophylaxis of leprosy, as defined by the WHO's AWaRe classification. Furthermore, we look for studies on antibiotics that showed sensitivity or less resistance after antimicrobial sensitivity testing (AST) on isolates from infected leprosy ulcers, as well as their AWaRe category.

RESULTS

There were 32 studies found, but only 5 of them met the inclusion criteria. They consisted of four cross-sectional studies and one descriptive retrospective study. A total of 19 antibiotics were identified in 5 studies, with 9 (47.4%) antibiotics in the access category, 8 (42.1%) antibiotics in the watch group, and 2 (10.5%) antibiotics in the reserve group.

CONCLUSION

As per our knowledge, this is the first study to explore antibiotics in leprosy treatment, chemoprophylaxis, and complications such as ulcer compliance with the AWaRe programme. Antimicrobial resistance is on the rise, which is a global issue that continues to pose challenges to clinical practices. This review may provide physicians with an overview of the current state of drug prescribing trends in leprosy, whether in accordance with the AWaRe classification in selecting the right drug when the use of antimicrobials is indicated and may also aid in rational drug prescribing.

Trends in antimicrobial consumption in Bhutan

Introduction

Antimicrobial use has been recognized as one of the main drivers of antimicrobial resistanceand it is, therefore, crucial to monitor the consumption and use of antimicrobials. This study was conducted to determine the consumption of antimicrobials in terms of defined daily doses (DDDs) per 1000 inhabitants per day (DIDs) at both national and dzongkhag levels in Bhutan, and to investigate trends from 2017 to 2019.

Methods

A retrospective analysis of antimicrobial consumption in healthcare facilities in Bhutan from 2017 to 2019 was undertaken using the national records of annual distribution of medicines. World Health Organization Anatomical Therapeutic Chemical (ATC) Classification System/DDD methodology was used for data collection and analysis.

Results

In 2019, the consumption of antimicrobials (ATC subgroup J01) for systemic use in healthcare facilities in Bhutan was 16.29 DIDs, compared with 14.39 DIDs in 2018 and 13.27 DIDs in 2017. The most commonly used subgroup of antimicrobials was the penicillin group of beta-lactams (J01C).

Conclusion

Antimicrobial consumption in Bhutan was found to be lower than the European Union and European Economic Area average, and lower compared with most Eastern European countries and some countries in the Western Pacific region. However, overall consumption in Bhutan increased steadily over the 3-year study period. This should be monitored carefully, and appropriate interventions to optimize antimicrobial use should be put in place in the near future.

Drivers of antibiotic use in Vietnam: implications for designing community interventions

INTRODUCTION

Antimicrobial resistance is a global challenge that threatens our ability to prevent and treat common infectious diseases. Vietnam is affected by high rates of antimicrobial resistant infections, driven by the overuse of antibiotics and the Vietnamese government has recognised antimicrobial resistance as a health security priority. This study aimed to understand how people in Vietnam use antibiotics in community settings, and the factors that impact their practices and decision-making regarding antibiotics.

METHODS

We conducted 43 qualitative in-depth interviews with 50 community members in two urban and two rural sites in Vietnam. We conducted iterative, inductive thematic analysis alongside data collection through a process of systematic debriefings based on detailed interview summaries. Through this process, we developed a coding framework that was then applied to transcribed interview data.

RESULTS

Frequent and indiscriminate use of antibiotics was driven by the powerful appeal that antibiotics held for many Vietnamese consumers. Consumers were discerning in making decisions in their purchase and use of antibiotics. Consumers' decisions were affected by perceptions of what constitutes high-quality medicine (effective, strong, accessible and affordable); privileging symptom control over diagnosis; social constructions of antibiotics as a trusted remedy with embodied evidence of prior efficacy, which is reinforced by advice from trusted sources in their community; and varied, generally incomplete, understanding of the concept of antibiotic resistance and its implications for individuals and for public health.

CONCLUSION

Antibiotic use at the community and primary care level in Vietnam is driven by community members' social and economic response to what constitutes effective healthcare, rather than biomedical logic. Community-based interventions to reduce unnecessary antibiotic use need to engage with the entangled socio-structural factors that 'resist' current public health efforts to ration antibiotic use, alongside biomedical drivers. This study has informed the design of a community-based trial to reduce unnecessary antibiotic use.

Determinants of trends in reported antibiotic use among sick children under five years of age across low-income and middle-income countries in 2005-17: A systematic analysis of user characteristics based on 132 national surveys from 73 countries

OBJECTIVES

This study aimed to analyze any reported antibiotic use for children aged <5 years with fever, diarrhea or cough with fast or difficult breathing (outcome) from low-income and middle-income countries (LMICs) during 2005-2017 by user characteristics: rural/urban residence, maternal education, household wealth, and healthcare source visited.

METHODS

Based on 132 demographic and health surveys and multiple indicator cluster surveys from 73 LMICs, the outcome by user characteristics for all country-years was estimated using a hierarchical Bayesian linear regression model.

RESULTS

Across LMICs during 2005-2017, the greatest relative increases in the outcome occurred in rural areas, poorest quintiles and least educated populations, particularly in low-income countries and South-East Asia. In low-income countries, rural areas had a 72% relative increase from 17.8% (Uncertainty Interval (UI): 5.2%-44.9%) in 2005 to 30.6% (11.7%-62.1%) in 2017, compared to a 29% relative increase in urban areas from 27.1% (8.7%-58.2%) in 2005 to 34.9% (13.3%-67.3%) in 2017. Despite these increases, the outcome was consistently highest in urban areas, wealthiest quintiles, and populations with the highest maternal education.

CONCLUSION

These estimates suggest that the increasing reported antibiotic use for sick children aged <5 years in LMICs during 2005-2017 was driven by gains among groups often underserved by formal health services.

Increase and Change in the Pattern of Antibiotic Use in Serbia (2010-2019)

The aim of this study was to determine and describe trends in antibiotics utilization in Serbia over a ten-year period. Data were retrieved from publicly available annual reports (2010-2019). The results were expressed as Defined Daily Dose (DDD) per 1000 inhabitants per day (DID). All calculations were performed using the DDD values for the 2020 Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) version for each year of the study, to account for the DDD changes during the study period. Antibiotics were classified using the WHO Access, Watch, Reserve (AWaRe) classification. Total utilization of antibacterials for systemic use increased from 17.25 DID in 2010 to 28.65 DID in 2019. A statistically significant increasing trend in the use of the Watch category antibiotics was observed. A tendency towards use of broad-spectrum antibiotics, apparent by a statistically significant increase in the rate of utilization of broad-spectrum macrolides, quinolones and third-generation cephalosporins vs. narrow-spectrum ones, as well as a significant increasing trend in the use of quinolones was identified. Total antibiotic utilization was found to be well above the European average. Several specific problem areas were identified, which requires further efforts to improve antibiotic prescribing. The present study provides the information needed to facilitate antibiotic stewardship in Serbia further and proposes specific interventions to optimize antibiotic use in Serbia.
