The Bush administration, in its final days, issued a federal rule Thursday reinforcing protections for doctors and other health care workers who refuse to participate in abortions and other procedures because of religious or moral objections.

Critics say the protections are so broad they limit a patient’s right to get care and accurate information. For example, they fear the rule could make it possible for a pharmacy clerk to refuse to sell birth control pills without ramifications from an employer.

Under long-standing federal law, institutions may not discriminate against individuals who refuse to perform abortions or provide a referral for one. The administration’s rule is intended to ensure that federal funds don’t flow to providers who violate those laws, Health and Human Services officials said.

“Doctors and other health care providers should not be forced to choose between good professional standing and violating their conscience,” said HHS Secretary Mike Leavitt.

The rule requires recipients of federal funding to certify their compliance with laws protecting conscience rights.
