The role of the pharmacist in the multidisciplinary approach to the prevention and resolution of drug-related problems in cancer chemotherapy

Background Clinical pharmacists have important roles in implementing scientifically valid knowledge and advice on safe, reasonable use of pharmaceuticals. Clinical pharmacy services were introduced and evaluated in oncology clinic in a tertiary university hospital. Methods A prospective interventional study was conducted from November 2017 to March 2018. Drug-related problems were classified using the Pharmaceutical Care Network Europe drug-related problem classification tool v8.01. The main outcome measure is the proposed interventions aimed at identification of the drug-related problems, the role of the pharmacists in the resolution, and the rate of acceptance of these recommendations by physicians. Results A total of 102 patients were included in the study, who were treated with at least two cycles of any cancer type and stage. A total of 55 (53.9%) patients had 251 drug-related problems. Drug-related problems mainly involved antihypertensive (31.6%), antidiabetic (17.8%), and herbal agents (31.6%). Treatment effectiveness was the major type of drug-related problems (50.2%) followed by treatment safety (29.1%). A total of 211 (100%) interventions were accepted and regarded as clinically relevant. Prescriber informed only were the most common types of intervention at the prescriber level. Eighty-six point four percent identified drug-related problems were solved, 9.8% of the problems were partially solved, 2.3% problems were unsolved. Conclusion Clinical pharmacy services may have optimized therapy effectiveness, prevent adverse effects and unclear/compliant problems. The pharmacist interventions were highly acknowledged by oncologists and patients; this may indicate the presence of a great convenience and need to implement Clinical pharmacy services in alternative hospitals in Northern Cyprus.
