Economic epidemiology is a field at the intersection of epidemiology and economics.Its premise is to incorporate incentives for healthy behavior and their attendant behavioral responses into an epidemiological context to better understand how diseases are transmitted.
In epidemiology, a non-pharmaceutical intervention (NPI) is any method used to reduce the spread of an epidemic disease without requiring pharmaceutical drug treatments. Examples of non-pharmaceutical interventions that reduce the spread of infectious diseases include wearing a face mask and staying away from sick people .
Epidemiological (and other observational) studies typically highlight associations between exposures and outcomes, rather than causation. While some consider this a limitation of observational research, epidemiological models of causation (e.g. Bradford Hill criteria) [7] contend that an entire body of evidence is needed before determining if an association is truly causal. [8]
Policy for population health "sets priorities" [2] and are a "guide to action to change what would otherwise occur". [2] Policies are based on "social sciences of sociology, economics, demography, public health, anthropology, and epidemiology" [4] and determine how outcomes can be accomplished are implemented at various levels.
A quasi-experiment is an empirical study used to estimate the causal impact of an intervention. Quasi-experiments shares similarities with experiments or randomized controlled trials, but specifically lack random assignment to treatment or control. Instead, quasi-experimental designs typically allow assignment to treatment condition to proceed ...
Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population, and application of this knowledge to prevent diseases.
Many theoretical studies of the population dynamics, structure and evolution of infectious diseases of plants and animals, including humans, are concerned with this problem. [27] Research topics include: antigenic shift; epidemiological networks; evolution and spread of resistance; immuno-epidemiology; intra-host dynamics; Pandemic; pathogen ...
Map out the causal chain (program theory) which explains how the intervention is expected to lead to the intended outcomes, and collect data to test the underlying assumptions of the causal links. Understand context, including the social, political and economic setting of the intervention.
