[Establishing endemic levels of ranges with computer spreadsheets].
Summary
This study introduces a new method for establishing disease outbreak surveillance ranges. It uses statistical software to calculate endemic levels, aiding in the detection of excess disease cases.
Area of Science:
- Epidemiology
- Biostatistics
Context:
- Defining epidemics requires establishing normal or expected disease levels.
- Surveillance systems need reliable methods to identify deviations from endemic disease rates.
Purpose:
- To present a novel methodology for developing endemic ranges for disease surveillance.
- To utilize statistical software for calculating historical disease rate means and confidence intervals.
Summary:
- This research details a new approach to defining endemic ranges using Quattro Pro and Excel.
- The methodology involves calculating the geometric mean of historical rates and confidence intervals.
- A procedure for cumulative endemic ranges is also described to monitor low-incidence events.
Impact:
- Enables more accurate identification of disease outbreaks and epidemics.
- Improves public health surveillance for both high and low incidence diseases.
- Provides a standardized method for setting expected disease levels.
