Identifying the right data sources is a fundamental step in the selection of ingredients. Common data sources in epidemiology include:
- Surveillance Systems: These provide continuous data on the incidence and prevalence of diseases. - Health Records: Electronic health records and medical charts offer valuable information about patient histories and treatment outcomes. - Surveys and Questionnaires: These can be used to gather data on self-reported behaviors, exposures, and health outcomes.
Choosing the right data source depends on the study objectives, the population of interest, and the type of data required.
