Follow-Up in Occupational Respiratory Diseases
The term “follow-up” can be used in different ways, either a restrictive one, meaning a particular type of epidemiological study (“prospective cohort study”), or an extended one; the latter being more suitable when applied to surveys in the field of occupational medicine and industrial hygiene. It is therefore justified to include in the word “follow-up” the whole of longitudinal procedures employed to take under control some environmental and/or biological situations (“environmental monitoring”, “biological monitoring”, “aimed surveys”, “repeat screening”). All these procedures can be used either separately for descriptive purposes or appropriately correlated among them for analytical ones.
