Irrational drug use and its associated factors at Debre Markos Referral Hospital's outpatient pharmacy in East Gojjam, Northwest Ethiopia

Assessing the impact of COVID-19 on prescription patterns and antibiotic use: Insights from three military health facilities

BACKGROUND

The COVID-19 pandemic disrupted health systems globally and there are suggestions it impacted antibiotics prescribing patterns in clinical practice.

OBJECTIVES

This study aimed to assess the effects of the COVID-19 pandemic on the prescribing patterns in three Nigerian military health facilities and investigate the factors associated with antibiotic prescriptions.

METHODS

This was a two-year cross-sectional retrospective study. Three hospitals and a total of 11,590 prescriptions were purposively and conveniently sampled respectively. The World Health Organisation (WHO) and International Network of Rational Use of Drugs (INRUD) prescribing indicators were used to assess for polypharmacy, injection use, use of antibiotics, use of generic drugs and prescriptions from essential drug lists for the periods of the pandemic and before the pandemic. Indicators from both periods were compared for statistical significance using the independent t-test. Generalized linear modelling was applied to assess the factors associated with antibiotic prescriptions. The relationship between the receipt of antibiotics and independent variables was presented using incident risk ratios (IRR).

RESULTS

Our findings showed that all five WHO/INRUD prescribing indicators were above the reference limit for the two-year study period. The study found there was a significant statistical difference between the COVID- and non-COVID-19 periods, with polypharmacy and antibiotic use indicators elevated during the pandemic compared to the latter. COVID-19 (IRR = 1.09), comorbidity (IRR = 1.74), pregnancy (IRR = 0.93), out-of-pocket payments (IRR = 1.10) and the inpatient department (IRR = 1.51) were associated with antibiotic prescriptions.

CONCLUSIONS

This provides insight on impact of the pandemic on prescription patterns and advocates for stewardship programs in clinical settings to ensure the rational use of drugs.

Factors affecting the medication literacy of older adults and targeted initiatives for improvement: a cross-sectional study in central China

Introduction

This study explored the state of rational drug use among older adults in central China, aiming to unveil factors influencing their medication literacy and proposing targeted improvement measures.

Methods

A cross-sectional study involving 454 participants aged 60 and above was conducted in Hubei province between February 1 and May 30, 2023, with data collected through face-to-face interviews by pharmacists. Multiple logistic regression analysis was conducted to determine factors that affected medication literacy.

Results

Of the 412 valid questionnaires, findings revealed inadequate knowledge of rational drug use among older adults in central China. Those who fully understood (105, 25.49%, OR = 9.349, p < 0.001, 95%CI = 3.884-22.502) or partially understood (228, 55.34%, OR = 3.295, p = 0.002, 95%CI = 1.548-7.013) drug instructions exhibited significantly higher medication literacy than those who did not understand (79, 19.17%). Subsequent research revealed a lack of awareness in reading drug instructions or difficulty in understanding them. Most older adults seldom heard of but exhibited high acceptance of medication guidance services.

Discussion

In conclusion, the ability to comprehend drug instructions significantly influenced the medication literacy of older adults. Initiatives such as revising age-appropriate drug instructions could effectively enhance rational drug use among this demographic.

Assessment of Legibility of Handwritten Prescriptions and Adherence to W.H.O. Prescription Writing Guidelines in Ahmadu Bello University Teaching Hospital Zaria - Kaduna State, Nigeria

Introduction: The issues of incorrectness and incompleteness for written prescriptions may result to dispensing errors and unintended outcomes of care. The objective of the study was to assess the legibility of handwritten prescriptions and adherence to W.H.O. prescription writing guidelines in Ahmadu Bello University Teaching Hospital Zaria. Method: A cross-sectional prospective study design was used, and existing prescriptions were sampled from selected in-patient and outpatient pharmacy units of Ahmadu Bello University Teaching Hospital Zaria. This was approved by the ethics and research committee of the institution. The prescriptions were then evaluated for quality based on the layout, legibility, and clarity of the details in the prescriptions and screened for medication errors. Result: The extent of prescribing drugs by generic name was (68.37%), the legibility percentage was moderate and the percentage of prescriptions in which details of the drug, route of administration, and duration of treatment were complete was 85.23%, 80.80%, and 82.40%, respectively. The doctor's signature (84.87%) was present in the prescriptions. Many of the prescribers did not use to indicate patients' weight, age, and clinic on prescriptions, these are deviations from good prescribing practices while total medication error was 38.01%. Conclusion: Prescribers have a duty of care to their patient and a professional duty to their colleagues (pharmacists) to ensure drug prescriptions are readily identifiable. Interventional techniques such as the use of printed or electronic prescriptions can improve the ease of interpreting information and reduce medication errors.

Evaluation of Rational Drug Use Based on WHO/INRUD Core Drug Use Indicators in a Secondary Care Hospital: A Cross-Sectional Study in Western Uganda

Purpose

Rational drug use (RDU) promotes safe, efficient, and cost-effective utilization of medicines in hospital settings. The aim of this study was to assess rational drug use based on the World Health Organization (WHO) and the International Network for Rational Use of Drugs (INRUD) core drug use indicators.

Patients and Methods

This prospective, descriptive, hospital-based cross-sectional study was conducted among patients attending the Outpatient Department of a secondary care hospital located in the Sheema District of Western Uganda. A total of 450 prescriptions were prospectively collected from eligible patients and subjected to evaluation by using the WHO/INRUD core drug use indicators (prescribing, patient care, and health-facility indicators).

Results

The average number of drugs prescribed per encounter was found to be 3.2 (optimal value=1.6-1.8). The percentages of drugs prescribed by their generic name (90.48%) and from the Essential Medicine List (96.23%) were close to the WHO reference (100%). The percentage of antibiotics (66.22%) and injections (25.22%) per encounter exceeded the WHO standards (antibiotics=20.0-26.8; injections=13.4-24.1). Among the patient-care indicators, the average consultation time (5.41 minutes), average dispensing time (131.03 seconds), percentage of medicines dispensed (76.11%), percentage of medicines adequately labeled (59.74%), and percentage of patients with dosage knowledge (49.50%) did not meet the WHO reference. Facility indicators such as the percentage of key medicines available in the stock (66.67%) did not conform to the WHO optimal value. The hospital made the EML hundred percent available to all practitioners.

Conclusion

The study concludes that the prescribing, patient care, and health facility indicators at Sheema District Secondary Care Hospital deviate from the optimal values recommended by the WHO. Therefore, this study indicates a need for improvement on these indicators and a requirement for the ongoing educational initiatives focused on rational drug prescribing, dispensing, and patient use in order to comply with the standards set by the WHO.

Prescribing Pattern and Associated Factors in Community Pharmacies: A Cross-Sectional Study Using AWaRe Classification and WHO Antibiotic Prescribing Indicators in Dire Dawa, Ethiopia

BACKGROUND

Antimicrobials are drugs that are more likely to trigger the development of resistance naturally. Thus, they need to be prescribed, dispensed, and administered with greater caution. To underline the significance of their proper usage, antibiotics are divided as AWaRe: Access, Watch, and Reserve. Timely evidence on medicine use, prescribing patterns, and the factors affecting prescribing of antibiotic and their use percentage from AWaRe classification would help decision-makers to draft guidelines that can enable more rational use of medicines.

METHODS

Prospective and cross-sectional study was conducted among seven community pharmacies in Dire Dawa to assess current prescribing practices related World Health Organization (WHO) indicators and AWaRe classification including antibiotic use and associated factors. Using stratified random sampling techniques, 1200 encounters were reviewed between 1 October and 31 October 2022, and SPSS version 27 was used for the analysis.

RESULTS

The average of medications per prescription was 1.96. Antibiotics were included in 47.8% of encounters, while 43.1% were prescribed from the Watch groups. In 13.5% of the encounters, injections were administered. In multivariate models, patient age, gender, and the number of medications prescribed were significantly associated to prescription of antibiotics. Antibiotics were about 2.5 times more likely to be prescribed to patients under the age of 18 years than to subjects 65 years and older [adjusted odds ratio (AOR): 2.51, 95% confidence interval (CI): 1.88-5.42; P < 0.001]. Men were also more likely than women to receive an antibiotic prescription (AOR: 1.74, 95% CI: 1.18-2.33; P = 0.011). Subjects who received more than two drugs were 2.96 times more likely to receive an antibiotic drug (AOR: 2.96, 95% CI: 1.77-6.55; P < 0.003). The probability of prescribing antibiotics was increased by 2.57 for every one-unit increase in the number of medications [crude odds ratio (OR): 2.57; 95% CI: 2.16-3.47; P < 0.002].

CONCLUSION

According to the present study, the amount of prescriptions with antibiotics at community pharmacies is much higher than the WHO standard (20-26.2%). The antibiotics prescribed from Access group were 55.3%, which is slightly lower than WHO recommended level (60%). The prescribing of antibiotics was significantly correlated to the patient's age, gender, and number of medications.

Diagnosis and Management of Adult Tuberculosis Patients Admitted to a Rural Hospital in Ethiopia

Background  Ethiopia is one of the countries in the world with the highest rate of tuberculosis (TB). The aim of this study is to describe the characteristics of the patients with TB admitted to a rural hospital in Ethiopia in terms of both diagnosis and clinical management. Methods A retrospective descriptive observational study was conducted. Data were collected from patients older than 13 years who were admitted to the Gambo General Hospital for TB between May 2016 and September 2017. The variables studied were age, sex, symptoms, human immunodeficiency virus (HIV) serology, nutritional status, presence of anemia, chest x-ray or other complementary tests, type of diagnosis (smear microscopy, Xpert MTB-RIF (Cepheid, Sunnyvale, California, USA), or clinical diagnosis), treatment received, outcome, and days of admission. Results One hundred eighty-six patients, aged 13 years and older, were admitted to the TB unit. About 51.6% were female, and the median age was 35 years (interquartile range (IQR) 25-50). Cough was the most frequent symptom on admission (88.7%), and contact with a TB patient was only recognized by 22 patients (11.8%). HIV serology was performed in 148 patients (79.6%); seven were positive (4.7%). About 69.3% met the criteria for malnutrition (body mass index (BMI) <18.5). Most patients, 173 (93%), presented with pulmonary TB and were new cases (94.1%). Patients were diagnosed by clinical parameters in 75% of cases. Smear microscopy was performed in 148 patients, of which 46 (31.1%) were positive, and Xpert MTB-RIF results were only obtained in 16 patients, of which 6 (37.5%) were positive. Chest x-rays were performed in most patients (71%) and were suggestive of TB in 111 (84.1%). The average length of hospital stay was 32 days (confidence interval (CI) 13-50.5). Women tend to be younger than men, have more extrapulmonary TB, and were admitted longer. Nineteen patients died during admission (10.2%). Patients who die were more frequently malnourished (92.9% of those who die were malnourished compared to 67.1% of those who did not die, p = 0.036), tend to be admitted for a shorter time than the survivors and receive more concomitant antibiotic treatment. Conclusions In this rural Ethiopian setting, patients admitted to the hospital for TB are often malnourished (67.1%), the main presentation is pulmonary, mortality is one in 10 admissions and very often receive antibiotics in association with TB treatment (40%).

Prevalence and Determinants of Household Medication Storage During the COVID-19 Outbreak in Southwest Ethiopia

Background

Most households worldwide keep medicines on hand for various reasons, including emergency use, treatment of acute and chronic diseases, and anticipated future use. Being infected or fear of getting COVID-19 in the current pandemic could increase the storage of drugs at home. Thus, this study aimed to assess the prevalence of household storage of medicines and associated factors in southwest Ethiopia during the COVID-19 outbreak.

Methods

A cross-sectional household survey was conducted from February 1 to May 30, 2022. Data on the extent of storage, storage conditions, their current status, disposal methods, among others, were collected through structured interviews and observations. The data were entered into EPI info, exported, and analyzed using Statistical Packages for Social Sciences (SPSS). Bivariate followed by multivariate logistic regression was used to identify associated factors. P-value <0.05 was used as a cut-off point to decide statistical significance.

Results

The magnitude of household medication storage was 48% (95% CI). Analgesics (28.7%) and antibacterial (21.1%) agents were the most predominant class of drugs stored in the households. The most significant proportion of the home-stored medications (34.7%) was reserved for future use, and 31.8% were for treating current medical conditions. The majority of the respondents (84.1%) had never heard/learned about the safe disposal ways of drugs. The presence of children aged less than 5 years in a household [AOR = 1.90 (1.19, 3.05)] and the existence of chronically sick patients in a household [AOR = 4.3 (2.25, 8.45)] were factors significantly associated with household medication storage.

Conclusion

The current study revealed a high prevalence of home medication storage; thus, to lessen or eliminate the negative consequences of storing medications at home, it is necessary to review the medication utilization chain and offer community-based training on proper medication storage and disposal techniques, including establishing take-back programs.

Evaluation of drug use pattern in adults’ outpatient clinics in a tertiary teaching hospital using WHO core prescribing indicators

Objectives

This study has evaluated the drug use pattern among adults attending the outpatient clinics of the Jordan University Hospital (JUH), by assessing the adherence of prescriptions to the World Health Organization (WHO) core prescribing indicators.

Methods

This is a cross-sectional study that was conducted during the period from October 2011 to January 2022 at JUH. Several prescriptions from 10 different adult outpatient clinics were reviewed to evaluate hospital adherence to the five WHO core prescribing indicators.

Key findings

To assess the WHO core prescribing indicators, data for 2451 prescriptions were reviewed. Around one-third of the patients (33.4%) were receiving polypharmacy (five medications or more). Results revealed that two core prescribing indicators were not following the standard values specified by the WHO; the average number of drugs prescribed per encounter (3.8 medications/prescription), and the percentage of drugs from the essential drug list (EDL) (54.1%). Endocrine clinics showed the highest average of drugs (6.3) per prescription and the highest percentage of prescriptions with injectable medicines (51.7%). On the other hand, ophthalmology clinics showed the highest percentage of prescriptions with antibiotics (29.9%) and the lowest percentage of drugs prescribed from the EDL at JUH (14.1%). Evaluating factors affecting the number of prescribed medications per encounter revealed that elderly patients (&gt; 60 years), being female, referring to the endocrine clinic, and having insurance have a higher average number of medications per encounter compared with others (P &lt; 0.05).

Conclusion

The proper prescribing practices in a sizable tertiary hospital in Amman, Jordan, are clarified by this study. The percentage of medications from EDL and the typical number of drugs/encounters did not comply with WHO requirements. The study findings should guide the Jordanian health policymakers in designing and implementing strategies to limit irrational prescribing practices and raise awareness of and ensure physician adherence to the national EDL.

Impact of pharmacist services on economic, clinical, and humanistic outcome (ECHO) of South Asian patients: a systematic review

Background

Pharmacists in high-income countries routinely provide efficient pharmacy or pharmaceutical care services that are known to improve clinical, economic, and humanistic outcomes (ECHO) of patients. However, pharmacy services in low- and middle-income countries, mainly South Asia, are still evolving and limited to providing traditional pharmacy services such as dispensing prescription medicines. This systematic review aims to assess and evaluate the impact of pharmacists’ services on the ECHO of patients in South Asian countries.

Methods

We searched PubMed/Medline, Scopus, EMBASE, CINAHL, and Cochrane Library for relevant articles published from inception to 20th September 2021. Original studies (only randomised controlled trials) conducted in South Asian countries (published only in the English language) and investigating the economic, clinical (therapeutic and medication safety), and humanistic impact (health-related quality of life) of pharmacists’ services, from both hospital and community settings, were included.

Results

The electronic search yielded 430 studies, of which 20 relevant ones were included in this review. Most studies were conducted in India (9/20), followed by Pakistan (6/20), Nepal (4/20) and Sri Lanka (1/20). One study showed a low risk of bias (RoB), 12 studies showed some concern, and seven studies showed a high RoB. Follow-up duration ranged from 2 to 36 months. Therapeutic outcomes such as HbA1c value and blood pressure (systolic blood pressure and diastolic blood pressure) studied in fourteen studies were found to be reduced. Seventeen studies reported humanistic outcomes such as medication adherence, knowledge and health-related quality of life, which were found to be improved. One study reported safety and economic outcomes each. Most interventions delivered by the pharmacists were related to education and counselling of patients including disease monitoring, treatment optimisation, medication adherence, diet, nutrition, and lifestyle.

Conclusion

This systematic review suggests that pharmacists have essential roles in improving patients’ ECHO in South Asian countries via patient education and counselling; however, further rigorous studies with appropriate study design with proper randomisation of intervention and control groups are anticipated.

Drug utilization pattern and adverse drug reactions of chemotherapy in pediatric patients at Muhimbili National Hospital, Tanzania

Background: Cancer is a highly debilitating non-communicable disease and an essential contributor to the global burden of disease. Pediatric patients are highly exposed to multiple drugs for the management of cancer. Monitoring drug utilization patterns helps to provide feedback to healthcare providers to ensure the rational use of medicines; as a result, it increases the therapeutic efficacy and decreases the frequency and severity of adverse drug reactions (ADRs). Therefore, this study assessed the utilization pattern and ADRs of chemotherapy in pediatric patients at Muhimbili National Hospital (MNH). Methods: A descriptive cross-sectional study was conducted for three months from February to April 2021 in pediatric cancer patients undergoing chemotherapy at MNH. A total of 123 children diagnosed with cancer and on chemotherapy were enrolled in this study. Patients' socio-demographics, clinical information, chemotherapy status, prescribed medications, and prevalence of ADRs were collected. Descriptive statistics was used in data analysis, whereby frequency and proportions were used to summarize data. Results: Out of 123 patients, 62.6% were male. Most patients received an average of four anticancer drugs. Vincristine (55.3%) was the most used anticancer drug, followed by cytarabine (44.7%) and methotrexate (42.3%). The most used adjuvant drugs were ondansetron (30.9%), hydrocortisone (27.6%), and piperacillin/tazobactam (23.6%). The percentage of drugs prescribed from the Tanzania Essential Medicine List (TEML) and World Health Organization (WHO) list was 66.4% and 93%. Most (87%) of the patients reported having experienced ADRs whereby nausea and vomiting (45.8%), hair loss (33.6%), and neutropenia (32.7%) were more prevalent ADRs reported. Conclusions: This study found the drug prescribing pattern to be in line with the essential medicine list, but the average number of drugs prescribed was higher than recommended. ADRs were prevalent among pediatric cancer patients.
