Chapter 9 Epidemiology General Concepts. Definitions. Epidemiology is the study of the determinants, occurrence, and distribution of health and disease in a defined population. Infection is the replication of organisms in host tissue, which may cause disease. A carrier is an individual with no overt disease who harbors infectious organisms.

Hazard and Risk When we refer to hazards in relation to occupational safety and health the most commonly used definition is ‘A Hazard is a potential source of harm or adverse health effect on a person or persons’. The terms Hazard and Risk are often used interchangeably but this simple example explains the difference between the two.

Hazard and Risk 1 what kind of effect could result from the specific exposure a person experienced, 2  the risk (or likelihood) that exposure to a hazardous thing or condition would cause an injury, or disease or some incidence causing damage, and. 3  how severe would the damage, injury or harm (adverse health effect) be from the exposure.here are many definitions for hazard but the more common definition when talking about workplace health and safety is: A hazard is any source of potential damage, harm or adverse health effects on something or someone under certain conditions at work.

risk 6. Workplace: Product of the consequence and probability of a hazardous event or phenomenon. For example, the risk of developing cancer is estimated as the incremental probability of developing cancer over a lifetime as a result of exposure to potential carcinogens (cancer-causing substances)..

Epidemiology A type of epidemiologic study where a group of exposed individuals (individuals who have been exposed to the potential risk factor) and a group of non-exposed individuals are followed over time to determine the incidence of disease. Start with a group of people with known exposure status (without disease)

Prevalence Prevalence in epidemiology is the proportion of disease found to have been affecting a particular population (typically a disease or a risk factor such as smoking or seat-belt use).

Incidence (epidemiology) Prevalence is the proportion of the total number of cases to the total population and is more a measure of the burden of the disease on society with no regard to time at risk or when subjects may have been exposed to a possible risk factor.ncidence should not be confused with prevalence, which is the proportion of cases in the population at a given time rather than rate of occurrence of new cases.

Defining Patient Populations Using Analytical Tools Risk stratification is an exciting methodology that assists in identifying outcomes for specific patient populations. Once a population has been identified, clinicians can intervene appropriately to promote a positive result. The ability to risk stratify saves healthcare systems a great deal of time, energy, and money.

- Epidemiology is the study of the distribution and determinants of disease in a human population. It is the basic science and fundamental practice of public health. Epidemiology is the study of the spread of disease. It helps scientists to predict how far a disease will spread, how much damage it may do, and plan treatment, the crea … tion of vaccines, and so forth. The current preparations for swine flu were a result of epidemiological studies.  . 7 people found this useful.

Risk assessment Risk assessment is the determination of quantitative or qualitative estimate of risk related to a well-defined situation and a recognized threat (also called hazard). Quantitative risk assessment requires calculations of two components of risk (R): the magnitude of the potential loss (L), and the probability (p) that the loss will occur. An acceptable risk is a risk that is understood and tolerated usually because the cost or difficulty of implementing an effective countermeasure for the associated vulnerability exceeds the expectation of loss.

- (But be careful, for there are several synonyms and related concepts that can easily be confused with each other: Population attributable risk; population attributable risk proportion; etiologic fraction; excess fraction) The attributable risk in a population depends on the prevalence of the risk factor and the strength of its association (relative risk) with the disease. where Pe is the prevalence of the exposure (e.g., proportion who are overweight) and RRe is the relative risk of disease due to that exposure.

What is Epidemiology and What Does an Epidemiologist Do? Epidemiology is the area of healthcare that deals with the incidence, distribution, and possible control of diseases, illnesses and other factors relating to health. Epidemiology is a field where trained epidemiologists study patterns of frequency and the causes and effects of diseases in human populations. Epidemiology provides the scientific footings for evidence-based medicine and allows placement of strategies for improvement in public health.

Risk Definition of risk: A probability or threat of damage, injury, liability, loss, or any other negative occurrence that is caused by external or internal vulnerabilities, and that may be avoided through preemptive action. 2. Finance: The probability that an actual return on an investment will be lower than the expected return.

Risk Priority Number (from Failure Modes and Effects Analysis) Formula: The Risk Priority Number, or RPN, is a numeric assessment of risk assigned to a process, or steps in a process, as part of Failure Modes and Effects Analysis (FMEA), in which a team assigns each failure mode numeric values that quantify likelihood of occurrence, likelihood of detection, and severity of impact.sing the Failure Modes and Effects Analysis (FMEA) Tool, conduct a thorough analysis of a high-risk process in the organization, assigning numeric values to each failure mode per the instructions, and generate an RPN.

Incidence (epidemiology) prevalence. The incidence of a disease is another epidemiological measure. Incidence measures the rate of occurrence of new cases of a disease or condition. Incidence is calculated as the number of new cases of a disease or condition in a speciﬁed time period (usually a year) divided by the size of the population
