What must a written directive for microspheres include?

A written directive for microspheres is a critical element in ensuring patient safety and adherence to regulatory requirements. Among the requirements, including the manufacturer is essential because it allows for traceability of the product and ensures that the specific brand and type of microspheres, which may vary in composition or intended use, are accurately documented. This traceability helps maintain consistency in treatment and supports the quality assurance processes essential in the administration of radioactive materials.

While patient identification, date of the procedure, and type of radiation used are all important aspects of documentation in a medical setting, the inclusion of the manufacturer is specifically vital in the context of microspheres, as this information helps to confirm that the correct product has been used according to the manufacturer's guidelines and licensing specifications. It ensures that the treatment is performed safely and effectively, in accordance with standards established by regulatory bodies.
