Using the Epidemiologic Triangle

To prepare for this Discussion, review Chapter 12 in the course textbook and the media program.

Then, read the following case study:

This is Debbie’s first year working as a nurse at the local health department in a rural county.

Most of her days are spent in the clinic seeing clients who often do not have health insurance.

Over the past month, Debbie has noticed that several young Hispanic men have come to the health

department, each diagnosed with tuberculosis. Debbie is concerned about what the outbreak of

tuberculosis among the migrant workers could mean for the community. Through a community health

profile, Debbie identifies the group of migrant farm workers as being at highest risk for

contracting tuberculosis.

Using the Epidemiologic Triangle concept, consider the relationship among causal agents,

susceptible persons, and environmental factors. Then, respond to the following:

•As a BSN-prepared community health nurse, what steps should Debbie take next?

•How might information systems be used to support Debbie’s efforts?
