Rationalizing prescription via deprescribing in oncology practice.

Abstract

To provide an integrated approach for deprescribing practice in oncology setting. The data on deprescribing in oncology settings has been retrieved from the PubMed, Scopus and Google Scholar. We used "deprescribing," "potentially inappropriate medication" and "cancer" as a keyword for the conducting general search. The articles relevant to guidelines or tools used to deprescribe in cancer care were included. The nature of cancer, its treatment strategies, adverse effects of therapy and multimorbidity impact negatively on quality of life (QoL). Further, they invite polypharmacy which puts the patient at higher risk of drug-related problems like drug interactions, adverse drug reactions and addition of potentially improper medications, etc. In older adults with cancer, the incidence of potentially inappropriate medications (PIMs) was between 41% and 52%. Over the decades, multiple strategies have been developed to assess the appropriateness of therapy. One such approach is deprescribing. OncPal and oncoSTRIP (Systematic Tool to Reduce Inappropriate Prescribing) are the cancer specific guidelines whereas BEERs criteria, Screening Tool to Alert to Right Treatment/Screening Tool of Older Person's Prescriptions criteria (START/STOPP criteria), medication appropriateness index (MAI) are the cancer nonspecific tools to identify PIM among cancer patients. Here, we provided an integrative approach and algorithm for deprescribing in oncology setting which includes patient and caregiver goals, life expectancy (LE), review of medications, determining medication appropriateness, assessment of time to benefit (TTB), symptomatic and asymptomatic care, identifying medications to cease, implementation of the plan, monitoring and reviewing. Deprescribing in oncology setting is a novel and effective patient-centric approach to counteract the use of PIM, which helps to mitigate polypharmacy, drug-drug interactions, and adverse effects.
