Antibiotic prescribing practice using WHO Access, Watch and Reserve classification and its determinants among outpatient prescriptions dispensed to elderly population in six community chain pharmacies in Asmara, Eritrea: a cross-sectional study.
To assess antibiotic prescribing practice and its determinants among outpatient prescriptions dispensed to the elderly population.
A prescription-based, cross-sectional study.
Six community chain pharmacies in Asmara, Eritrea.
All outpatient prescriptions dispensed to the elderly population (aged 65 and above) in the six community chain pharmacies in Asmara, Eritrea.
Data were collected retrospectively, between 16 June 2023 and 16 July 2023. Antibiotic prescribing practice was assessed using the 2023 World Health Organization (WHO) Access, Watch and Reserve (AWaRe) classification system. Descriptive statistics and logistic regression were performed using IBM SPSS (V.26.0). P values less than 0.05 were considered as significant.
Of the 2680 outpatient prescriptions dispensed to elderly population, 35.8% (95% CI: 34.0, 37.6) contained at least one antibiotic. Moreover, a total of 1061 antibiotics were prescribed to the elderly population. The most commonly prescribed antibiotics were ciprofloxacin (n=322, 30.3%) and amoxicillin/clavulanic acid (n=145, 13.7%). The Access category accounted for the majority of antibiotics (53.7%) with 32.1% from the Watch category. Prescriber qualification (Adjusted Odds Ratio (AOR)= 0.60, 95% CI: 0.44, 0.81) and polypharmacy (AOR= 2.32, 95% CI: 1.26, 4.27) were significant determinants of antibiotic prescribing in the elderly population. Besides, sex (AOR=0.74, 95% CI: 0.56, 0.98), prescriber qualification (AOR=0.49, 95% CI: 0.30 to0.81) and level of health facility (AOR 0.52, 95% CI 0.34 to 0.81) were significant determinants of a Watch antibiotic prescription.
Antibiotics were prescribed to a considerable number of the elderly population, with more than half of them falling into the Access category. Further efforts by policy-makers are needed to promote the use of Access antibiotics while reducing the use of Watch antibiotics to mitigate risks associated with antimicrobial resistance.

Inappropriate medication prescribing, polypharmacy, potential drug-drug interactions and medication regimen complexity in older adults attending three referral hospitals in Asmara, Eritrea: a cross-sectional study.
Older adults often face several chronic illnesses that require them to take multiple medications. The increased number of prescribed medications has led to more complex medication regimens, putting older adults at a higher risk of potential drug-drug interactions, inappropriate medication prescribing, and adverse events. This study aimed to assess inappropriate prescribing practices, polypharmacy, medication regimen complexity, and their determinants in older adults.
A cross-sectional study was conducted among older adults (aged 65 years and above) who visited three referral hospitals in Asmara, Eritrea, between June and August, 2023. A stratified random sampling technique was used, and data were collected from patient prescriptions, medical cards, and through interviews with a questionnaire. Inappropriate medication prescribing was evaluated using STOPP (Screening Tool of Older Person's Prescriptions)/ START (Screening Tool to Alert to Right Treatment) criteria version 3. Potential drug-drug interactions (pDDIs) and medication regimen complexity (MRC) were assessed using Lexi-comp drug interaction checker and MRC index, respectively. Descriptive statistics, logistic regression, Pearson's correlation coefficient, independent samples t-test, one-way Analysis of Variance, and paired t-test were employed using IBM SPSS (version-26.0).
A total of 430 respondents, with a similar male to female ratio, were included. The prevalence of polypharmacy was 5.3% (95%CI: 3.2, 7.5). Moreover, the prevalence of clinically significant pDDI was 51% (95%CI: 46, 56). The most common medicines involved in clinically significant pDDIs were enalapril (n = 179) and acetylsalicylic acid (n = 124). The presence of chronic illness (AOR = 7.58, 95%CI: 3.73, 15.39) and the number of drugs prescribed (AOR = 2.80, 95%CI: 1.91, 4.10) were predictors of clinically significant pDDIs. The prevalence of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) were 27.4% (95% CI: 23.4, 31.8) and 13.3% (95% CI: 10.3, 16.7), respectively. The most common PIMs were long-acting sulfonylureas (n = 63) and aldosterone antagonists (n = 19). Besides, proton pump inhibitors (PPIs) (n = 41) and cardio-selective beta-blockers (n = 14) were the most common PPOs identified. Age (AOR: 0.95, 95% CI: 0.92, 0.98), presence of chronic illness (AOR: 1.51, 95% CI: 0.81, 2.80), and number of drugs prescribed (AOR: 2.01, 95% CI: 1.51, 2.69) were significant factors associated with PIM. MRCI score was a significant determinant of PPO (AOR: 1.25, 95% CI: 1.14, 1.38). The mean (SD) of the overall MRCI score was 9.1 (3.7), with dose frequency being the major contributor. The number of drugs prescribed was a determinant of MRCI score (r = 0.625, p < 0.001).
Inappropriate medication prescribing and clinically significant drug-drug interactions were common among older adults, highlighting the need for immediate attention from policymakers, program managers, and healthcare professionals.

Antibiotic prescription sources and use among under-5 children with fever/cough in sub-Saharan Africa.
Childhood febrile illness is among the leading causes of hospital admission for children <5 y of age in sub-Saharan Africa (SSA). Antibiotics have played a pivotal role in enhancing health outcomes, especially for children <5 y of age. Antibiotics prescription pattern evidence exists for SSA, however, prescription sources (either from qualified or unqualified sources) and use among children with fever or cough have not been explored. Thus the present study assessed antibiotic prescription sources and use among children <5 y of age with fever and cough in SSA.
We used Demographic and Health Survey data from 37 countries with a total of 18 866 children <5 y of age who had fever/cough. The surveys span from 2006 to 2021. The dependent variable was antibiotics taken for fever/cough based on prescriptions from qualified sources. The data were weighted using sampling weight, primary sampling unit and strata. A mixed-effects logistic regression model (both fixed and random effects) was fitted since the outcome variable was binary. Model comparison was made based on deviance (-2 log likelihood) and likelihood ratio tests were used for model comparison. Variables with p≤0.2 in the bivariable analysis were considered for the multivariable mixed-effects binary logistic regression model. In the final model, the adjusted odds ratio (AOR) with a 95% confidence interval (CI) and p<0.05 in the multivariable model were used to declare a significant association with taking antibiotics for fever/cough prescribed from qualified sources.
The percentage of unqualified antibiotic prescriptions among children <5 y of age who had a fever/cough and took antibiotics was 67.19% (95% CI 66.51 to 67.85), ranging from 40.34% in Chad to 92.67% in Sao Tome. The odds of taking antibiotics prescribed from unqualified sources for fever/cough among children <5 y of age living in rural areas were 1.23 times higher (AOR 1.23 [95% CI 1.13 to 1.33]) compared with urban children. The odds of taking antibiotics prescribed from qualified sources for fever/cough among children <5 y of age whose mothers had primary, secondary and higher education decreased by 14% (AOR=0.86 [95% CI 0.79 to 0.93]), 21% (AOR 0.79 [95% CI 0.72 to 0.86]) and 21% (AOR 0.79 [95% CI 0.65 to 0.95]) compared with those whose mother had no formal education, respectively.
The study showed that the majority of the children who received antibiotics obtained them from unqualified sources in the 37 SSA countries. Our findings underscore the significance of addressing healthcare disparities, improving access to qualified healthcare providers, promoting maternal education and empowering mothers in healthcare decision-making to ensure appropriate antibiotic use in this vulnerable population. Further research and interventions targeted at these factors are warranted to optimize antibiotic prescribing practices and promote responsible antibiotic use in the management of fever and cough in children <5 y of age.
