Pharmacovigilance and Pharmacoeconomics of Cancer Chemotherapy Medications in a Tertiary Care Hospital: Protocol for a Prospective Observational Cohort Study
ABSTRACT
Background:
Despite being a major burden in low- and middle-income countries in India, the understanding of cancer and its treatment remains limited. Adverse drug reactions (ADRs) from chemotherapy, polypharmacy, drug interactions and the cost of care also pose challenges for patient safety and health economics.
Objective:
This protocol describes the design of a prospective, observational, cross-sectional study that will evaluate chemotherapy drugs based on their usage, ADRs, and drug interactions, as well as undertake pharmacoeconomic analyses, including cost-effectiveness analysis, cost-utility analysis, and budget impact analysis to guide safe and cost-effective cancer treatment.
Methods:
The research will involve 67 adult cancer patients on chemotherapy in the oncology department of a tertiary care hospital in India for eight months. The Case Record Form will be used for data collection. Pharmacovigilance estimates will be done using standardised instruments (WHO-UMC scale, Naranjo algorithm, Hartwig and Siegel scale, Schumock and Thornton criteria). Economic analyses will include cost analysis, cost-effectiveness analysis (ICER), cost-utility analysis (ICUR) and budget impact analysis. Polypharmacy (use of >=5 drugs) and drug-drug interactions will also be assessed.
Results:
The study will confirm a high burden of ADRs, polypharmacy, and financial toxicity with chemotherapy. Results will demonstrate the link between prescription complexity, safety and cost.
Conclusions:
Linking pharmacovigilance with pharmacoeconomics will support rational prescribing, encourage generic and biosimilar uptake, and ultimately improve safety, affordability, and access to cancer treatment. Clinical Trial: CTRI/2025/10/096700 (Registered on: 31/10/2025)
