Medication-related problems and adverse drug reactions in Ethiopia: A systematic review

Moderate and serious adverse reactions to antimicrobials among hospitalized children: A systematic review

AIMS

This systematic review aimed to investigate the occurrence of moderate and severe adverse drug reactions (ADRs) to antimicrobials among hospitalized children.

METHODS

The PubMed/Medline, Cochrane Library, Embase, Web of Science, Scopus, Lilacs and CINAHL databases were searched in April 2023 to systematically review the published data describing the characteristics of moderate and severe ADRs to antimicrobials among hospitalized children. The search was carried out without date restrictions, up to the search date (April, 2023).

RESULTS

At the end of the selection process, 30 articles met the inclusion criteria. Cutaneous reactions were the primary serious clinical manifestations in most articles (19/30), followed by erythema multiforme (71 cases), Stevens-Johnson syndrome (72 cases), and toxic epidermal necrolysis (22 cases). The main antimicrobials involved in moderate and severe ADRs were penicillins, cephalosporins and sulfonamides. Regarding the primary outcomes, 30% (9/30) of the articles reported deaths, and 46.7% (14/30) of studies reported increased lengths of hospital stay, need for intensive care, and transfer to another hospital. Regarding the main interventions, 10% (3/30) of the articles mentioned greater monitoring, suspension, medication substitution or prescription of specific medications for the symptomatology.

CONCLUSIONS

The findings of this review could be used to identify areas for improvement and help health professionals and policymakers develop strategies. In addition, we emphasize the importance of knowing about ADRs so that there is adequate management to avoid undesirable consequences.

Clinical Pharmacist-Led Medication Review in Hospitalized Confirmed or Probable Patients with COVID-19 During the First Wave of COVID-19 Pandemic

Objectives

Drug-related problems (DRPs) result in serious problems among hospitalized patients, high rates of morbidity and mortality, and increased healthcare costs. This study aimed to identify DRPs by clinical pharmacist-led medication review in hospitalized probable patients with coronavirus disease-2019 (COVID-19) during the first wave of the COVID-19 pandemic.

Materials and Methods

This retrospective cross-sectional study was conducted at the COVID-19 inpatient services of a tertiary university hospital in Türkiye for 3 months (between March 2020 and June 2020) and included hospitalized confirmed or probable COVID-19 patients. The World Health Organization and Turkish Ministry of Health Guidelines case definitions were used to define confirmed and probable COVID-19 patients. Six clinical pharmacy residents provided medication review services during their education and training. DRPs were classified based on the Pharmaceutical Care Network Europe V9.00. The physician's acceptance rate of clinical pharmacists' recommendations was assessed.

Results

Among 202 hospitalized patients with probable or confirmed COVID-19, 132 (65.3%) had at least one drug-related problem. Two hundred and sixty-four DRPs were identified. Drug selection (85.6%) and dose selection (9.2%) were the most common causes of these problems. Among the 80 clinical pharmacist interventions, 48.8% were accepted by the physicians.

Conclusion

Clinical pharmacists identified a significant number of DRPs during the COVID-19 pandemic, particularly those related to drug interactions and drug safety, such as adverse drug reactions. This study highlights the importance of detecting and responding to DRPs in the COVID-19 pandemic.

Medication-related problems among patients with cervical cancers at oncology centers of University of Gondar comprehensive specialized hospital: A hospital-based retrospective study

INTRODUCTION

Though drugs play indispensable role in the treatment of cervical cancer, they are associated with medication-related problems (MRPs). Hence, the present study was aimed to investigate MRPs among patients with cervical cancer.

METHODS

A hospital-based retrospective study was employed at the oncology center of University of Gondar Comprehensive Specialized Hospital. All patients with cervical cancer diagnosis from January 1, 2016 to December 31, 2020, were included. Stata version 16/MP for Windows was used for description and analysis. Logistic regression analysis was employed.

RESULTS

A total of 124 patients with cervical cancer were included. Paclitaxel and cisplatin (69.4%) combination were the most widely used treatment regimen. MRPs were found in 59.7% patients, with a mean of 2.22 ± 1.13. Subtherapeutic dose (24.4%), the need for additional drug therapy (22.6%), and adverse drug reactions (22%) were the most prevalent MRPs. Being >50 years (adjusted odds ratio (AOR) = 15.37, 95% confidence interval (CI) = 2.25-105.09, p = 0.005), treated with ≥5 medications (AOR = 7.00, 95% CI = 2.65-18.49, p < 0.001), and being stage III (AOR = 15.43, 95% CI = 2.92-81.47, p = 0.001) and stage IV (AOR = 8.41, 95% CI = 1.35-52.44, p = 0.023) were independent predictors of MRPs.

CONCLUSION

More than half of patients with cervical cancer had one or more MRPs. Being older, patients taking polypharmacy, stage III and IV patients were significantly associated with the development of MRPs. As most of the cervical patients experienced one or more MRPs, clinical pharmacy service should be strengthened to optimize drug therapy to reduce unwanted adverse events.

A combination of Beers and STOPP criteria better detects potentially inappropriate medications use among older hospitalized patients with chronic diseases and polypharmacy: a multicenter cross-sectional study

BACKGROUND

Research on potentially inappropriate medications (PIM) and medication-related problems (MRP) among the Chinese population with chronic diseases and polypharmacy is insufficient.

OBJECTIVES

This study aimed to investigate the prevalence of PIM and MRP among older Chinese hospitalized patients with chronic diseases and polypharmacy and analyze the associated factors.

METHODS

A retrospective cross-sectional study was conducted in five tertiary hospitals in Beijing. Patients aged ≥ 65 years with at least one chronic disease and taking at least five or more medications were included. Data were extracted from the hospitals' electronic medical record systems. PIM was evaluated according to the 2015 Beers criteria and the 2014 Screening Tool of Older Persons' Prescriptions (STOPP) criteria. MRPs were assessed and classified according to the Helper-Strand classification system. The prevalence of PIM and MRP and related factors were analyzed.

RESULTS

A total of 852 cases were included. The prevalence of PIM was 85.3% and 59.7% based on the Beers criteria and the STOPP criteria. A total of 456 MRPs occurred in 247 patients. The most prevalent MRP categories were dosages that were too low and unnecessary medication therapies. Hyperpolypharmacy (taking ≥ 10 drugs) (odds ratio OR 3.736, 95% confidence interval CI 1.541-9.058, P = 0.004) and suffering from coronary heart disease (OR 2.620, 95%CI 1.090-6.297, P = 0.031) were the influencing factors of inappropriate prescribing (the presence of either PIM or MRP in a patient).

CONCLUSION

PIM and MRP were prevalent in older patients with chronic disease and polypharmacy in Chinese hospitals. More interventions are urgently needed to reduce PIM use and improve the quality of drug therapies.

Patterns of Medication Management and Associated Medical and Clinical Features among Home-Dwelling Older Adults: A Cross-Sectional Study in Central Portugal

Ageing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of home-dwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face structured interviews. Frailty, cognitive status, medication management and clinical and sociodemographic variables were evaluated. Descriptive and inferential statistics were calculated. The mean participant age was 76.6 ± 7.1 years, 53.6% of participants were women, and 40.2% of participants lived alone. More than half were classified as having frailty (58.9%), almost one-fifth (19.6%) presented with a moderate cognitive impairment had more than one disease, and 60.7% were polymedicated. No associations were found between polymedication and medication self-management, the use of over-the-counter medications, living alone, having a poor understanding of pharmacological therapy and/or pathology, or having more than one prescriber. Self-management was associated with age, the number of medications, frailty and cognitive status. Binary logistic regressions showed that cognitive impairment had statistically significant differences with medication management, having a poor understanding of pharmacological therapy and/or pathology, having one prescriber and the use of medications not prescribed by physicians. Interventions to prevent medication-related problems in home-dwelling older adults are recommended.

Clinical Pharmacist Intervention on Drug-Related Problems among Elderly Patients Admitted to Medical Wards of Northwest Ethiopia Comprehensive Specialized Hospitals: A Multicenter Prospective, Observational Study

Background: Drug therapy in the elderly needs an emphasis on age-related changes in drug pharmacokinetics and pharmacodynamics profile. Hospitalized elderly patients are at risk of more than one disease and polypharmacy associated with these; they are at risk of drug-related problems. This study aimed to assess the role of clinical pharmacy on identifying and resolution of drug-related problems among elderly patients admitted to medical ward of Northwest Ethiopia comprehensive specialized hospitals. Methods: A multicenter prospective observational study was conducted. A systematic sampling technique was used. The identified drug-related problem was recorded and classified using Cipolle, and adverse drug reaction was assessed using Naranjo algorithm of adverse drug reaction probability scale, and Medscape was used for drug-drug interaction. Data were analyzed by using STATA software version 14.1. Logistic regression was used, and results were reported as odds ratios (ORs) with 95% Confidence intervals with $P\text{value}<0.05$ statistically significant. Result: A total of 389 study participants were included in the study. About 266 (68.4%) of the participants had at least a single drug-related problem. About 503 drug-related problems were identified with a mean of 1.32 (CI: 1.27-1.36) drug-related problem per patient. The three-leading categories of drug-related problems were dose too high 108 (21.5%), nonadherence 105 (20.9%), and adverse drug reaction 96 (19.1%). Alcohol use ( $\text{AOR}=2.2$ , 95CI%: 1.23-3.94), source of the drug ( $\text{AOR}=2.85$ , 95CI%: 1.63-4.98), length of hospitalization ( $\text{AOR}=2.32$ , 95CI%: 1.37-3.95), number of comorbidities ( $\text{AOR}=1.48$ , 95CI%: 1.09-1.99), and polypharmacy ( $\text{AOR}=3.06$ , 95CI%: 1.72-5.46) were important risk factors for drug-related problems. From the intervention provided, 84.7% were accepted by prescribers. Among the total drug-related problems 67.4% of the problem was totally solved. Conclusion: This study revealed that DRPs were high among elderly patients admitted to medical ward of Northwest Ethiopia. Comorbidity, length of hospitalization, ploy-pharmacy, payer, and alcohol drinker were more likely to developed drug-related problems. Treatment optimizations were also done by clinical pharmacists and interventions were well accepted by prescribers.

Assessment of Adverse Drug Events, Their Risk Factors, and Management Among Patients Treated for Multidrug-Resistant TB: A Prospective Cohort Study From Pakistan

Background: Multidrug-resistant tuberculosis (MDR-TB) is a growing public health problem. Treatment regimens used against MDR-TB are costly, prolonged, and associated with more side effects as compared with the drug-susceptible tuberculosis. This study was framed to determine the incidence of adverse drug events, risk factors, and their management in MDR-TB patients.

Methods: This prospective follow-up cohort study was conducted at the site of programmatic management of drug-resistant TB located at the Pakistan Institute of Medical Sciences, Islamabad. All patients, irrespective of their age, gender, and ethnicity, were included in the study. Adverse drug events were observed in patients at different time points during the study. Patients enrolled for the treatment from January 2018 were prospectively followed till December 2020 up to their end treatment outcomes.

Results: Out of 126 MDR-TB patients enrolled for treatment, 116 met the inclusion criteria and were included in the final analysis. Most patients (50.9%) were between 18 and 45 years of age. A minimum of one adverse event was experienced by (50.9%) patients. Of all the adverse events, gastrointestinal disorders were more frequent (47.4%), followed by arthralgia (28.4%) and psychiatric disturbance (20.6%). Furthermore, multivariate analysis showed a significant association with the incidence of adverse events in patients with age group above 60 years (odds ratio (OR) 4.50; 95% CI 1.05-19.2), active smokers (OR 4.20; 95% CI 1.31-13.4), delayed reporting to the TB center (OR 4.03; 95% CI 1.34-12.1), and treatment without bedaquiline regime (OR 3.54; 95% CI 1.23-10.1). Most of the patients (94.6%), counseled by the pharmacist, were found to be satisfied with the information provided and looked for more pharmacist counseling opportunities in the management of MDR-TB.

Conclusion: Current findings recommend that ADEs might be well managed by timely identification and reporting. Bedaquiline coupled with other active medications lowered the chance of ADEs in MDR-TB patients. Elderly patients, active smoking behavior, and those who have a delay in the treatment initiation are more prone to ADEs. Clinical pharmacist’s contribution to TB control programs may help caregivers and patients concerning the rational use of medication, early detection, and management of ADEs.

Knowledge, Attitude, and Practice of Medical, Pharmacy, and Nursing Students Towards Pharmacovigilance and Adverse Drug Reaction Reporting at University of Gondar College of Medicine and Health Sciences, Northwest Ethiopia: A Cross-Sectional Study

BACKGROUND

The adequate knowledge, attitude, and practice (KAP) of pharmacovigilance and ADRs reporting is crucial for health care students.

OBJECTIVE

This study aimed at assessing the KAP of final-year medical, pharmacy, and nursing (MPN) students towards pharmacovigilance and ADRs reporting at the University of Gondar, College of Medicine and Health Sciences, Northwest Ethiopia.

METHODS

A cross-sectional study was conducted among 296 final-year MPN students at the University of Gondar College of Medicine and Health Sciences from November 1, 2020 to January 30, 2021. A close-ended, structured, self-administered questionnaire was used for data collection prospectively. SPSS^® (IBM Corporation) version 24 was used to analyze the data with descriptive and inferential statistics. The comparison of the KAP of groups was made by using a Kruskal-Wallis test and Mann-Whitney U-test. Statistical significance was declared at a p-value < 0.05.

RESULTS

Among 296 participants, the majority of them had a poor level of knowledge (69.9%), practice (95.9%), and moderate attitude (62.5%) towards pharmacovigilance and ADRs reporting. The median (interquartile range) score of the students' knowledge (maximum score = 15), attitude (maximum score = 50), and practice (maximum score = 5) towards PV and ADR reporting was 6 (5-8), 32 (28.25-35), and 1 (0-1), respectively. The KAP of the students has shown differences with age, sex, hearing of the term PV, and discipline. A lack of training on ADRs (49%) reporting and not knowing where and how to report ADRs (47.3%) were among the main reasons of MPN students for not reporting ADRs.

CONCLUSION

A majority of final-year MPN students had poor knowledge, practice, and a moderate attitude towards PV and ADRs reporting. The school of medicine, pharmacy, and nursing should adequately cover the issue of PV and ADRs reporting in the undergraduate curriculum.
