Purpose of Research

To assess the impact of obtaining documented informed consent on

participation & informed decision-making during population-based newborn screening for inborn errors of metabolism (IEM) using

tandem mass spectrometry (MS/MS)

Introduction to Newborn Screening in California

• Mandatory newborn screening (NBS) program allows refusal for religious reasons only

• 18 month supplemental screening research project required written informed consent to ensure voluntary MS/MS screening

Informed Consent Process

Hospital staff use yes or no stickers

Women choose or decline MS/MS screening

Women get 2nd booklet at hospital

Patients ask questions of providers or 1-800 #

Prenatal care providers educate patients

State educates prenatal care providers

State IRB review

Overview of Methods

• Tracked uptake of MS/MS screening in prospective cohort by hospital

• Surveyed prenatal care providers by mail• Conducted 5 focus groups with 31 pregnant

women

Focus Group Questions• Introductions?• How many received IIP

booklet?• What do you think of it?• Advantages/Concerns?• Feelings about making

the decision?• What information do

you think should be in the IIP booklet?

• What information is most important?

• What would influence you to not have test?

• How else would you like to receive this info?

• Importance of choosing to participate?

• What should the State address before making it mandatory?

What Participants Told Us

• Benefits and risks not understood• Importance of testing not conveyed• Purpose of research not obvious • Didn’t hear from prenatal provider but want to• Choice is important, but not to all• Don’t overwhelm with dense or confusing text• Provide more information in their words

Page 15: The Impact of Obtaining Documented Informed Consent on MS/MS Screening L.A. Faulkner 1, L.B. Feuchtbaum 2, M. Hanlon 1, F.W. Lorey 2, K. Velazquez 2, and

Burdens of Informed Consent

• Increased time and effort for Genetic Disease Branch, State IRB, and hospitals

• Reduced population screened– 354,000 for MS/MS vs. 756,000 mandatory NBS – <1% refusal in mandatory NBS vs. 10 – 50% non-

acceptance in MS/MS– 52 diagnosed disorders in screened population vs.

12 (59 expected) in non-screened population• Didn’t meet parents’ needs

Recommendations for Population-based Research

• Obtain waiver of informed consent, if possible, by demonstrating:– Minimal risk to participants– Participant rights not adversely affected– Informed consent is impractical– Educational materials still provided

• Improve educational materials, especially by using parents’ words

• Reduce barriers for prenatal care providers (e.g. combine prenatal and newborn screening materials)
