In practical effect, I think it is an anti-miscarriage law. Every woman who experiences an accident during pregnancy will be subjected to a witch hunt if this law goes into effect IMHO.
Another midwestern state -- Kansas, maybe -- has passed a law requiring doctors to publish information on individual abortions. Names and addresses are not required, but county of residence is. In rural, low-population areas, information such as race, age, marital status, etc. can easily be combined to identity the person.
