Activities in this area cover the full range of support services for trial centres in the conduct of clinical trials. This involves the planning and preparation of study visits as well as patient care and documentation. Good communication with the staff involved is the basis for fulfilling administrative and logistic duties such as file maintenance or the handling of trial medication. It is also essential in preparing for monitoring visits, audits or inspections and in ensuring compliance with regulatory requirements or timelines. Study nurses make a valuable contribution towards a smooth course of action in clinical trials as considerable additional effort beyond routine patient care must be provided in a clinical trial.
