Identification and Resolution of Drug-Related Problems among Childhood Cancer Patients in Ethiopia

Drug-related problems in cancer patients: A systematic review

BACKGROUND

Cancer patients are at a significantly increased risk of drug-related problems due to multiple drugs. An inclusive review of drug-related problems would offer an approach for healthcare providers to decrease the frequency of drug-related problems in cancer patients. The purpose of this study was to assess all characteristic components of drug-related problems in cancer patients, and explore actions taken to resolve the detected drug-related problems the results could be used as a baseline for epidemiology and potential related risk factors for drug-related problems in cancer patients.

METHODS

The present systematic review was done according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search consisted of studies listed from January 2015 and up to May 2023. A systematic review was carried out using an electronic database with a combination of Medical subject Headings of key words Medical Subject Heading terms.

RESULTS

This evaluation included 17 studies from 11 different nations having 11 prospective and 6 retrospective studies. Pharmaceutical Care Network Europe classification system is the most commonly used to classify the drug-related problems. The prevalence of drug-related problems varied from 9.6% to 92.8%. The key predictors of the drug-related problems were age, polypharmacy, multiple comorbidities, and the stage of the disease.

CONCLUSION

Drug-related problems are significantly more common among cancer patients. The age, polypharmacy, multiple comorbidities, and the stage of the malignancy all enhance the risk of acquiring drug-related problems. This review raises awareness of drug-related problems, encourages their early detection, and emphasizes the necessity for framing effective drug-related problem management strategies which will enhance patient care.

Pediatric oncology services in Nepal: A special focus on pharmacy practice

The role of clinical pharmacists or oncology pharmacists in pediatric oncology has been established as important in anticancer regimen review, dose calculation, recommendation, chemocounseling, identification of drug-related problems, its resolution, and, prevention and monitoring of adverse drug reactions within high-income countries. With several hospitals providing pediatric oncology services in Nepal, clinical pharmacist involvement in these hospitals is very poor. Upon reviewing the reputed organization and association focused on pediatric oncology pharmacy practice, it looks imperative for Nepal to initiate clinical pharmacy services which will further help in improving patient health outcomes. As such in this commentary, we try to accentuate the pediatric oncology services and pediatric pharmacy practice within Nepal and try to pinpoint the potential areas for clinical pharmacists to focus if they intend to provide services in pediatric oncology pharmacy practice.

Management Practice and Drug Related Problems and Its Contributing Factors Among Cervical Cancer Patients at Oncologic Center in Ethiopia: A Hospital-Based Retrospective Study

Introduction

In cervical cancer therapy, there is a high prevalence of drug-related problems (DRPs) due to the high toxicity and complexity of most antineoplastic regimens. However, there is a paucity of data about DRPs among patients with cervical cancer in Ethiopia. Hence, the present study was aimed at investigating management practices and DRPs among patients diagnosed with cervical cancer.

Methods

A registry-based retrospective cohort study was employed among cervical cancer patients at the oncology center of Felege Hiwot Comprehensive Specialized Hospital (FHCSH). All patients with a histologically confirmed diagnosis of cervical cancer from January 2016 to December 2020 were included. Relevant information was recorded by reviewing medical records. The possibility of DRPs was evaluated by comparing with standard guidelines. Logistic regression analysis was employed.

Results

A total of 184 cervical cancer patients were included, with a mean age of 50.2±10.7 years. A total of 216 DRPs were identified from 93 cervical cancer patients, translating to a prevalence of 50.5% and a mean of 2.32±1.11 DRPs per patient. ADR (27.3%), DDI (25%), and the need for additional drug therapy (22.2%) were the most prevalent DRPs. DRPs were associated with the presence of co-morbidity (AOR = 4.23, 95% CI = 1.78–10.05, p = 0.001), complications (AOR = 2.99, 95% CI = 1.28–6.99, p = 0.011), being treated with ≥5 medications (AOR = 5.1, 95% CI = 2.38–10.95, p < 0.001), being stage II (AOR = 0.14, 95% CI = 0.02–0.90, p = 0.038), and stage III (AOR = 0.04, 95% CI = 0.01–0.32, p = 0.003).

Conclusion

Cisplatin-based chemotherapy was the frequently used therapeutic option. Co-morbidity and complication status, number of medication and stage of cancer were significantly associated with DRPs. The study highlights the need of clinical pharmacy services to optimize drug therapy and reduce DRPs.

Effect of Pharmacist-Led Interventions on Physicians' Prescribing for Pediatric Outpatients

Background: Children are at high risk of drug-related problems, increased risk of treatment failures, and high treatment costs. We aimed to evaluate the effect of pharmacist-led interventions on physicians’ prescribing for pediatric outpatients. Methods: A prospective study with pre- and post-intervention measurement assessment was conducted to collect pediatric outpatients’ prescriptions during the pre-intervention period (January 2020) and post-intervention (August 2020) at a children’s hospital in Vietnam. Drug-related problems were identified and categorized according to Pharmaceutical Care Network Europe (PCNE), version 9.1. The intervention program was developed based on the results of pre-intervention observations. After the intervention, prescriptions were evaluated. Statistical tests were used to compare the proportions of drug-related problems before and after the intervention and to identify factors related to drug-related problems. Results: There were 2788 out of 4218 (66.1%) prescriptions with at least one drug-related problem before the intervention. Of these drug-related problems, the most common was inappropriate timing of administration and incorrect dosage (36.1% and 35.6%, respectively). After the intervention, the percentage of prescriptions with at least one drug-related problem was 45.5% (p < 0.001). Most of the drug-related problem types decreased significantly (p < 0.05). The binary logistic regression analysis results showed that in addition to pharmacists’ intervention, patients’ gender, primary disease, comorbidity status, and the total number of drugs prescribed were also factors related to drug-related problems. Conclusions: Drug-related problems in pediatric outpatients were quite common. Pharmacists’ intervention helped to improve the prevalence and types of drug-related problems.

Identification of drug-related problems followed by clinical pharmacist interventions in an outpatient pharmacotherapy clinic

WHAT IS KNOWN AND OBJECTIVE

Pharmacotherapy is an essential strategy for the treatment of many medical conditions especially chronic disease and often involves multiple medications being used simultaneously. Increasing the use of medications may pose some challenges to safe and effective drug therapy and if not identified and prevented by the pharmacists eventually can lead to drug-related problems (DRPs). The present study aimed to examine the incidence of DRPs in Iranian patients and to evaluate patients' adherence to the clinical pharmacist interventions as well as the physicians' acceptance of these recommendations.

METHODS

This study was conducted in a university-affiliated outpatient pharmacotherapy clinic over a 22-month period. Patients aged 18 years and older with at least one chronic disease receiving at least four medications were included in the study. The patients were interviewed by a clinical pharmacist for comprehensive medication review. DRPs were identified using the DOCUMENT classification system. Recommendations were provided by the clinical pharmacist including interventions involving patient and/or physician to resolve DRPs. The patients were followed up after 2 weeks to evaluate their compliance and physician acceptance of clinical pharmacist recommendations.

RESULTS AND DISCUSSION

Two hundred patients were included in this study. Overall, 875 DRPs were identified with an average of 4.37 per patient. The most prevalent DRPs were related to patient education or information (22.8%), undertreated indications (17.4%) and patient compliance (17.2%). The most common drugs associated with DRPs were alimentary and metabolism (22.2% of DRPs) followed by the cardiovascular system (19.2%) and nervous system (9.6%) medications. The DRP incidence correlated with gender only and was higher in females (p = 0.019). The clinical pharmacist provided 912 interventions with an average of 4.56 and 1.04 interventions per patient and per DRPs respectively. Patient education (41.3%), medication initiation or discontinuation (24.5%), and non-pharmacological interventions (12.9%) were the most common clinical pharmacist interventions. Out of 912 interventions, 665 were followed up, out of which 427 were patient dependent and 228 involved physicians. The patient's compliance with clinical pharmacist recommendations was 81.2%. The physician acceptance rate of the recommendations was 44.1%.

WHAT IS NEW AND CONCLUSION

The study shows that especially designed services such as pharmacotherapy clinics running by clinical pharmacists are necessary to detect and resolve DRPs in an effective way. The high compliance rate of the patients indicates patients' confidence in the clinical pharmacist services provided in the pharmacotherapy clinic. The low acceptance rate of the physicians highlights the need to improve interprofessional collaboration between clinical pharmacists and physicians in an outpatient setting.
