Outpatient antibiotic prescribing for acute respiratory infections in Vietnamese primary care settings by the WHO AWaRe (Access, Watch and Reserve) classification: An analysis using routinely collected electronic prescription data.

This study aims to investigate patterns of antibiotic prescribing and to determine patient-specific factors associated with the choice of antibiotics by the World Health Organization's Access-Watch-Reserve (WHO AWaRe) class for acute respiratory infections (ARIs) in rural primary care settings in northern Vietnam. We retrospectively reviewed health records for outpatients who were registered with the Vietnamese Health Insurance Scheme, visited one of 112 commune health centres in 6 rural districts of Nam Dinh province, Vietnam during 2019, and were diagnosed with ARIs. Patient-level prescription data were collected from the electronic patient databases. We used descriptive statistics to investigate patterns of antibiotic prescribing, with the primary outcomes including total antibiotic prescriptions and prescriptions by WHO AWaRe group. We identified patient-specific factors associated with watch-group antibiotic prescribing through multivariable logistic regression analysis. Among 193,010 outpatient visits for ARIs observed in this study, 187,144 (97.0%) resulted in an antibiotic prescription, of which 172,976 (92.5%) were access-antibiotics, 10,765 (5.6%) were watch-antibiotics, 3366 (1.8%) were not-recommended antibiotics. No patients were treated with reserve-antibiotics. The proportion of watch-antibiotic prescription was highest amongst children under 5-years old (18.1%, compared to 9.5% for 5-17-years, 4.9% for 18-49-years, 4.3% for 50-64-years, and 3.7% for 65-and-above-years). In multivariable logistic regression, children, district, ARI-type, comobid chronic respiratory illness, and follow-up visit were associated with higher likelihood of prescribing watch-group antibiotics. The alarmingly high proportion of antibiotic prescriptions for ARIs in primary care, and the frequent use of watch-antibiotics for children, heighten concerns around antibiotic overuse at the community level. Antimicrobial stewardship interventions and policy attention are needed in primary care settings to tackle the growing threat of antibiotic resistance.

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

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. 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. 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. 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.

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

To review community-level consumption of antibiotics in rural Vietnam, according to the WHO Access, Watch, Reserve (AWaRe) classification of 2019, and identify factors associated with the choice of these antibiotics. In this cross-sectional study, data on antibiotic purchases were collected through a customer exit survey of 20 community antibiotic suppliers in Ba Vi District, Hanoi, between September 2017 and July 2018. Antibiotic consumption was estimated through the number of antibiotic encounters, the number of DDDs supplied and the number of treatment days (DOTs) with antibiotics, and analysed according to the AWaRe classification. The factors associated with watch-group antibiotic supply were identified through multivariable logistic regression analysis. In total, there were 1342 antibiotic encounters, with access-group antibiotics supplied in 792 encounters (59.0%), watch-group antibiotics supplied in 527 encounters (39.3%) and not-recommended antibiotics supplied in 23 encounters (1.7%). No reserve-group antibiotics were supplied. In children, the consumption of watch-group antibiotics dominated in all three measures (54.8% of encounters, 53.0% of DOTs and 53.6% of DDDs). Factors associated with a higher likelihood of watch-group antibiotic supply were: private pharmacy (OR, 4.23; 95% CI, 2.8-6.38; P < 0.001), non-prescription antibiotic sale (OR, 2.62; 95% CI, 1.78-3.87; P < 0.001) and children (OR, 2.56; 95% CI, 1.84-3.55; P < 0.001). High consumption of watch-group antibiotics was observed, especially for use in children. The frequent supply of watch-group antibiotics at private pharmacies reconfirms the need for implementing pharmacy-targeted interventions in Vietnam.
