Measuring demand in epidemiology involves several methodologies:
- Surveillance Systems: Public health surveillance systems collect data on disease occurrence, helping to estimate the demand for healthcare services and interventions.
- Health Surveys: Surveys like the National Health Interview Survey (NHIS) and the Behavioral Risk Factor Surveillance System (BRFSS) gather information on health behaviors, conditions, and access to care.
- Hospital and Clinical Data: Data from hospitals and clinics provide insights into healthcare utilization patterns and help estimate demand for specific services.
