In their article, Zweiner and Ginsburg1 use descriptive epidemiology as a tool to provide new and useful information. At the same time, they show the usefulness and the limitations of this method and reemphasize specific issues in the diagnosis and management of anticholinesterase insecticide poisonings.
Descriptive epidemiology is useful for describing the natural history of disease, for evaluating trends in health or disease, and for making comparisons among different subgroups. It helps identify problems or topics for research (ie, hypothesis generation).2 Descriptive epidemiology is often used for evaluating clinical toxicology data. The systematic reworking of a large case series permits review of diagnostic criteria and accuracy and critique of accepted or novel therapy.
