Natural History Study
A natural history study is a preplanned intended to track the course of the disease. Its purpose is to identify demographic, genetic, environmental, and other variables (e.g., treatment modalities, concomitant medications) that correlate with the disease’s development and outcomes. Natural history studies are likely to include patients receiving the current standard of care and/or emergent care, which may alter some manifestations of the disease.
A breach of security (or security breach) occurs where a stated organisational policy or legal requirement regarding information security has been violated. However, every incident which suggests that the confidentiality, integrity or availability of the information has been compromised can be considered a security incident. Every security breach will always be initiated by a security incident which, only if confirmed, may become a breach.
