The administrator of a local hospital notices that many patients admitted for Salmonella infection indicate that they drink unpasteurized milk from a local dairy. The dairy has resisted pasteurizing the milk because the state inspections do not always find Salmonella contamination. The hospital administrator decides to conduct a hospital-based study that may show a strong association between unpasteurized milk consumption and Salmonella cases in the community.
1. What study design should the hospital administrator select? Why?
2. What can be concluded from this hospital-based study with respect to the association of consuming unpasteurized milk and Salmonella infection?
Based on the scenario, this solution responds to the two questions on aspects of epidemiology e.g. type of design the hospital administrators should select, as well as any conclusions that could be made from this hospital-based study with respect to the association of consuming unpasteurized milk and Salmonella infection. Supplemented with a resource on epidemiology.
