Ans: A
Berkson's bias creates the likelihood of finding a false association between the two illnesses. Although medical and hospital records contain comprehensive information about patients seeking services, they do not provide a completely representative or valid picture of community health. Not all clients with health problems receive medical attention; so medical records are biased by including only those that do. Also, medical documentation is not always complete. Hospitalized patients are also more likely to have coexistent illnesses. The National Electronic Disease Surveillance System is a conduit to exchange information health information to public health departments; however, it is only voluntary.
