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.
