Assessment of medicine use among outpatients at healthcare facilities in Ethiopia using the WHO's prescribing indicators with a focus on antibiotics: a systematic review and meta-analysis

A Systematic Review on Evaluation of WHO Core Prescribing Indicators Across Healthcare Facilities in Low Resource Asian Setting: A Case of Nepal

Inappropriate drug use is a significant global health issue, particularly in low-resource settings. This systematic review evaluates drug utilization across healthcare facilities in Nepal, a low-resource setting, using WHO core prescribing indicators to identify areas for improvement. A systematic review was conducted by searching literature in PubMed, Embase, CINAHL, INRUD bibliography, NepJOL, NepMed, and Google Scholar. Original studies assessing at least one WHO prescribing indicator in healthcare settings of Nepal were included. Eligible studies were analyzed descriptively and through proportional meta-analysis using a random-effects model. Eighty-eight studies were identified involving 2108 healthcare facilities and 60 191 patient encounters. The average of three drugs per encounter (95% CI: 2.5-3.2) was determined. Generic prescribing occurred only in 21.8% (95% CI: 15.6%-28.8%) prescriptions, showing a decline trend. Antibiotics were prescribed in 64.4% (95% CI: 57.7%-70.8%) encounters, with higher prevalence in secondary and tertiary care settings. Injectables were prescribed in 22.9% encounters (95% CI: 12.2-35.8). Drugs prescribed from WHO and Nepal essential medicine lists accounted for 53.0% (95% CI: 41.1-64.7) and 54.4% (95% CI: 47.7-60.9), respectively. The evaluation of drug utilization in Nepal suggested that the standards for WHO core prescribing indicators were not met, including overuse of antibiotics, underuse of essential medicines, and minimal generic prescribing. Targeted interventions, including prescriber education, policy reforms, enhanced monitoring, and regular prescription audits, are essential to promote rational prescribing and improve drug-related outcomes, including an opportunity to reduce antimicrobial resistance.

The Pattern of Medicine Use in Ethiopia Using the WHO Core Drug Use Indicators

Introduction

Rational medicine use is an appropriate prescribing, dispensing, and patient use of medicines for the diagnosis, prevention, and treatment of diseases. It is affected by several factors. Irrational use of medicine is a widespread problem at all levels of care. This review is aimed at assessing the medicine use pattern in health facilities of Ethiopia using the medicine use pattern developed by WHO/INRUD.

Methods

Relevant literature was searched from Google Scholar, PubMed, Hinari, Web of Science, and Scopus using inclusion and exclusion criteria. A systematic review was used to summarize the medicine use pattern in health facilities of Ethiopia, and that WHO core drug use indicators were employed.

Result

From 188 searched studies, 30 literatures were reviewed. The average number of drugs per encounter was 2.11. The percentage of encounters with antibiotics and injection was 57.16% and 22.39%, respectively. The percentage of drugs prescribed by generic name and from an essential drug list was 91.56% and 90.19%, respectively. On average, patients spent 5.14 minutes for consultation and 106.52 seconds for dispensing. From prescribed drugs, 67.79% were dispensed, while only 32.25% were labeled adequately. The availability of key essential medicines was 64.87%. The index of rational drug use value was 7.26. Moreover, the index of rational drug prescribing, index of rational patient-care drug use, and index of rational facility-specific drug use were 3.74, 2.51, and 1.01, respectively.

Conclusion

Ethiopian health facilities were faced with antibiotic overprescribing, short consultation, and dispensing times, poor labeling of medicines, poor availability of key drugs, and nonadherence to the essential drug list. Routine, multidisciplinary awareness creation, and regulation should be implemented to promote rational medicine use at a national level.

Evaluation of Rational Use of Medicine Using WHO/INRUD Core Drug Use Indicators at Teda and Azezo Health Centers, Gondar Town, Northwest Ethiopia

Background

Despite medicines are a major contributor to the health and well-being of the community, irrational use of medicines is being a serious public health crisis with significant harmful implications for patients, healthcare systems, and communities as a whole.

Objective

This study was aimed at evaluating the rational use of medicine using the World Health Organization/Network of Rational Use of Drugs (WHO/INRUD) core drug use indicators at Teda and Azezo health centers of Gondar town, northwest Ethiopia.

Methods

A cross-sectional study was conducted among 1200 prescription papers retrospectively, and 60 patients prospectively at two health centers of Gondar town, northwest Ethiopia from May 01/2019 to April 30/2020. The data were collected using a standard data collection checklist. Data were analyzed using SPSS^® version 24. The data were analyzed descriptively by using mean, frequency, and proportion.

Results

Prescribing indicators: From a total of 2595 prescribed medicines, 94% of them were prescribed by generic name; percent encounters with injection was 9.5±0.28%, percent encounters with antibiotics was 73.85±0.35%, and 100% of medicines were prescribed from the essential medicine list of Ethiopia. Patient care indicators: Only 16.7% of the patients knew the correct dosage of their medications, and 17.5% of dispensed medicines were adequately labeled. From the prescribed medications, only 77.17% were actually dispensed. Average consultation and dispensing time were 5.35 minutes and 40.24 seconds, respectively. Facility-specific indicators: Only 83.5% of key medicines were available in the health centers.

Conclusion

According to the WHO/INRUD core drug use indicators, rational medicine use is not achieved in terms of most components of the prescribing, patient care, and facility-specific indicators. Therefore, both health centers should work towards promoting the rational use of medicines.
