Development and Evaluation of an e-Learning Module for Low- and Middle-Income Countries on the Safe Handling of Chemotherapy Drugs.

Despite the growing use of chemotherapy drugs in resource-constrained settings, training opportunities on safe handling practices are lacking. This study's objectives were to develop and evaluate an e-learning training module on the safe handling of chemotherapy drugs to strengthen knowledge and practices in low- and middle-income countries (LMICs). The module's curriculum was developed using the Six-Step Approach for Curriculum Development for Medical Education. Asynchronous, self-paced, e-learning lessons within the module were created and uploaded onto a free online platform, Pharm-Ed. The study ran online from January to April 2021. Participant recruitment was done using convenience sampling through various channels (social media, communities of practice). Training module effectiveness was evaluated using knowledge assessments (a pre-test and post-test study design) and participant satisfaction. We developed a comprehensive e-learning module on the safe handling of chemotherapy drugs comprising 11 asynchronous, self-paced, e-learning lessons. Eighty-two participants (68% pharmacists and 17% pharmacy students) from 17 countries completed at least one lesson, with a total of 259 lessons completed. Evaluation of the different lessons showed significant improvements in theoretical knowledge (p < 0.01) in all except one lesson and a high degree of participant satisfaction. As the use of anti-cancer drugs in LMICs will continue to increase, this e-learning module is an effective means to address the lack of training opportunities on the safe handling of chemotherapies for healthcare workers in these countries. The module could be integrated into a multi-modal approach aimed at reducing occupational exposure and increasing patient safety in cancer care centers.

The safe handling of chemotherapy drugs in low- and middle-income countries: An overview of practices.

INTRODUCTION: The rising burden of cancer in low- and middle-income countries (LMICs) has led to substantial efforts to improve access to chemotherapy. The present study's objectives were to obtain an overview of the safe handling practices implemented in LMICs' healthcare facilities when dealing with chemotherapy drugs and to prioritize opportunities for improving them. METHODS: We conducted an online survey, from June 2018 to April 2019, among LMIC healthcare facilities dealing with chemotherapy drugs. Facilities were asked to self-assess their chemotherapy handling processes using Cyto-SAT, a self-assessment tool incorporating 134 items organized into 10 domains (management, personnel, logistics, prescription, preparation, administration, incident management, waste management, cleaning, and patient counselling). Data were recorded on an online platform (www.datapharma.ch/cyto-SAT). RESULTS: The survey enrolled 53 healthcare facilities (15 from low-income, 26 from lower-middle-income, and 12 from upper-middle-income countries). The median level of implementation of safe practices was 63% (Q1:39%-Q3:77%). Facilities in low-income countries (LICs) reported lower median levels of safe practices than middle-income countries (MICs) [LICs: 32% (Q1:24%-Q3:62%), Lower-MICs: 63% (Q1:49%-Q3:70%), Upper-MICs: 85% (Q1:77%-Q3:93%)]. The biggest differences between country categories were observed in the domains related to personnel, preparation processes, and incident management. CONCLUSION: This overview of practices highlighted a large variability and major gaps in the safe handling of chemotherapy drugs in LMICs. Improvement strategies are needed to increase patient and staff safety and limit environmental contamination, especially in LICs. Safe handling programs should be part of continuing efforts to improve access to quality cancer drugs and should be integrated into national cancer control programs.

Development and Proof of Concept of an Audit Toolkit for the Safe Handling of Cytotoxic Drugs in Low- and Middle-Income Countries.

PURPOSE: Chemotherapies are considered high-risk drugs for patient and staff safety. Considering the rising burden of cancer and the increasing use of chemotherapy drugs in low- and middle-income countries (LMICs), promoting continuous improvements in the safety and quality of practices in these settings is essential. This paper describes the development and proof of concept of a toolkit to audit chemotherapy handling practices in the health care facilities of LMICs. METHODS: A steering committee defined the audit method and the toolkit content. Several checklists were developed to facilitate the audit and data collection. Items included in checklists were derived from key reference works on safe handling. Different tools were validated using Delphi surveys and expert reviews. Audits of pilot sites were performed to test the toolkit's applicability and relevance. RESULTS: The toolkit contains a 134-item global assessment tool for the different processes at each step of the medication pathway and three step-specific observation checklists to assess different health workers' practices during the prescription, preparation, and administration of chemotherapies. The toolkit also proposes using a surface-wipe sampling method to measure any cytotoxic contamination of the immediate environment. The toolkit was tested in three teaching hospitals in Africa. CONCLUSION: The toolkit developed was successfully implemented in a variety of LMIC settings, providing a comprehensive evaluation of the quality and safety of the chemotherapy drug handling practices in participating health care facilities. This toolkit can help facilities in LMICs to implement a new approach to continuously improving the quality and safety of their practices and ultimately ensure patient and staff safety.

Cyto-SAT: A self-assessment tool for the safe handling of cytotoxic drugs adapted for use in low- and middle-income countries.

INTRODUCTION: The handling of cytotoxic medicines is a high-risk process for human and environmental health. Considering the rising burden of cancer in low- and middle-income countries (LMICs), we aimed to develop, validate, and pilot test a self-assessment tool to support the implementation of safe handling practices and promote continuous quality improvement for cytotoxic drug management in LMICs. METHODS: First, the self-assessment tool Cyto-SAT was developed and validated. Key sources on the safe handling of cytotoxic medicines were reviewed to derive items addressing safety and quality aspects at every stage of the process. A two-round online Delphi survey was conducted to validate and prioritize the items. The validation rules in the first and second rounds were defined as ≥65% and ≥75% agreement, respectively. Then, intended users in healthcare facilities in LMICs evaluated the Cyto-SAT tool in a pilot test. They were asked to fill out an online evaluation questionnaire. RESULTS: Twenty-seven experts from 13 high-income countries and LMICs participated in the Delphi survey. Final expert consensus was achieved for 134/137 (97.8%) items. Consensus on priority was achieved for 52 of 134 (38.8%) items. The final Cyto-SAT tool comprises 134 items in 10 domains and 28 subdomains covering the whole cytotoxic drug handling process (https://pharmed.datapharma.ch/cyto-sat_en/). Staff from 34 institutions in 28 LMICs completed the Cyto-SAT evaluation. Almost all of them reported total agreement or agreement with its usefulness (96%), applicability (94%), usability (98%), and acceptability (97%). CONCLUSION: Cyto-SAT is the first self-assessment tool designed to assist professionals in LMICs in the safe handling of cytotoxic drugs. The pilot test revealed that Cyto-SAT is a useful and highly appreciated tool that supports practice improvement in LMICs. Cyto-SAT will be used in an international survey to obtain a global overview of handling practices in various LMIC settings.

In vitro biotransformation of imatinib by the tumor expressed CYP1A1 and CYP1B1.

The main objective of the study was to examine the biotransformation of the anticancer drug imatinib in target cells by incubating it with oxidoreductases expressed in tumor cells. The second objective was to obtain an in silico prediction of the potential activity of imatinib metabolites. An in vitro enzyme kinetic study was performed with cDNA expressed human oxidoreductases and LC-MS/MS analysis. The kinetic parameters (Km and Vmax) were determined for six metabolites. A molecular modeling approach was used to dock these metabolites to the target Abl or Bcr-Abl kinases. CYP3A4 isozyme showed the broadest metabolic capacity, whereas CYP1A1, CYP1B1 and FMO3 isozymes biotransformed imatinib with a high intrinsic clearance. The predicted binding modes for the metabolites to Abl were comparable to that of the parent drug, suggesting potential activity. These findings indicate that CYP1A1 and CYP1B1, which are known to be overexpressed in a wide range of tumors, are involved in the biotransformation of imatinib. They could play a role in imatinib disposition in the targeted stem, progenitor and differentiated cancer cells, with a possible contribution of the metabolites toward the activity of the drug.
