mea culpa; after pulling up some old links that took me nowhere, I dove into the Public Health compiled statutes and the administrative codes and you are correct: IL has vit K on the books now. (They didn't back when my oldest was born) Also, where there used to be an exemption clause in the Infant Eye Disease Act, there is no longer, That being said, there are still exemptions on the books for both the newborn screen/pku:
Section 661.60 Exemption
Whenever a newborn screening test is not performed because a parent or guardian presents a written statement of objection on the basis of religious tenets and practices, documentation shall be maintained by the facility of birth or by the primary health care provider. Objection based on religious tenets and practices is the only ground for exemption. The Department shall be notified in writing.
...and the hearing screen:
1) The provisions of the Act shall not apply when the newborn's parent or guardian objects in writing on the grounds that the screening conflicts with his/her religious beliefs or practices and presents a written objection to a physician or other person whose objective it is to obtain the screening.
I'm still not understanding how, barring extenuating circumstances (such as circ-ing or known vd), the patient couldn't sign a written refusal and not get harassed. I really think Prentice is getting ridiculous with this. How in the world does every other hospital in the city let you opt out, not to mention homebirths? I'm so sorry your client had to deal with that. I could never ever do what you do - I'd blow my stack on a daily basis.
