Study Design

What problem does it solve?

This Skill provides guidance and best practices for designing environmental epidemiology studies, specifically time series and case-crossover analyses, and for planning exposure assessment strategies.

Core Features & Use Cases

• Common Designs: Explains Time Series and Case-Crossover study designs, including their units, strengths, and weaknesses.
• Data Guidance: Details typical variables and formats for outcome data from mortality registers and hospital admissions.
• Exposure Assessment: Outlines methods for assessing exposure, such as fixed monitors, spatial interpolation, and satellite data.
• Key Considerations: Highlights critical factors like minimum series length, population stability, and the harvesting debate.
• Use Case: A researcher needs to design a study investigating the impact of air pollution on respiratory hospital admissions. This skill can help them choose between a time series or case-crossover design and understand how to collect and align exposure and outcome data.
