| Health Surveillance Definition | activity which involves obtaining information about EMPLOYEES health and which helps protect employees from health risks |
| Health Surveillance Three Goals | 1. Protecting the health of employees by early detection of adverse changes or disease; 2. Collecting data for detecting or evaluating health hazards; 3. Evaluating control measures. |
| Three Determinants of Health Surveillance | 1. there is a disease associated with the substance in use (e.g. Asthma, Dermatitis, Cancers); 2. it is possible to detect the disease or adverse change and reduce the risk of further harm; 3. the conditions in the workplace make it likely that the disease will appear. |
| Epidemiology Definition | study of factors and influencing the frequency and distribution of disease, injury, and other health-related events and their causes |
| Definition of: Cause | an event, characteristic or condition that precedes a disease without which the disease or condition would not have occurred. |
| Definition of: Determinant | attribute or circumstance that effects the liability of an individual to be exposed or when exposed to develop the disease or condition |
| Definition of: Confounding Variable | factor significantly associated both with the cause and disease in the population, but not the cause itself e.g. smoking/ Cancer |
| Definition of: Absolute Risk | Incidence of disease within a defined population |
| Definition of: Relative Risk | ratio of incidence rate in an exposed group to the incidence rate in a non-exposed group |
| Definition of: Attributable Risk | difference between incidence rates in exposed and non-exposed groups. |
| Definition of: Descriptive Studies | Demonstrates patterns of disease and associations within a population. They can track mortality or morbidity over time and compare incidence/prevalence between regions or groups with different characteristics e.g. occupation. |
| Pros and Cons of Descriptive Studies | Data can be analysed from data that is routinely collected, however specific studies are sometime required to obtain data using surveys, as routine data collection might not be in a usable format, have variations in diagnostic criteria and have gaps or inconsistencies. Designed studies must be aware of error and bias, including subject variation, observer variation and limitations of the surveying methodologies including sample size, validity and randomness. |
| Definition of: Cohort Study | Longitudinal study where a group/population is identified as being possibly exposed to an agent under investigation. It may take many years and aims to identify the characteristics of those who develop the disease. |
| Definition of: Case-control study | Recruitment of individuals already having the disease, with their case histories compared to a control group of subjects not affected by the disease but drawn from the same general population. |
