[Development of a standardized guide for optimizing drug adherence information to be dispensed during a pharmaceutical counseling with a multiple myeloma patient: Initial validation]

Abstract

The safety of the community treatment with oral anticancer therapies is a strong theme of the cancer plan 2014-2019. The objective of this study was to develop a Pharmaceutical Counseling Guide to improve medication adherence in patients treated for multiple myeloma with oral anticancer therapies. A multidisciplinary professional working group selected a list of relevant medication adherence-related items that served as the framework for the design of the pharmaceutical counseling support materials in patient-accessible language. The readability, understanding and memorization of the information were validated in ten patients treated for myeloma. Twelve items were selected for treatment information (5 items), treatment planning (5 items), and adverse drug effects (2 items). A pharmacist guide, a patient guide, a medication schedule, and three self-questionnaires to evaluate medication knowledge and understanding of patients were developed. The patient test resulted in changes in these documents. This study carried out the initial validation of documents to standardize the pharmaceutical counseling for patients treated for myeloma so that it can be reproduced from one patient to another regardless of the pharmacist, by standardizing the information issued. This study needs to be completed by a final validation in myeloma patients, free from oral anticancer therapies.
