Hospital & Midwives Training Maternal and Child Health Genomics and Newborn Screening Program
Why Do Newborn Screening? • Required by Indiana law (Indiana Code 16-41-17) • Early detection & early treatment of newborn screening disorders: • Lessens severity of complications • Improves quality of life • Lack of early detection & treatment can lead to: • Severe mental retardation • Inadequate growth & development • Death
Mission of ISDH Newborn Screening Program • Ensure that every newborn in Indiana receives state-mandated screening for all 46 designated conditions • Maintain a centralized program to ensure that infants who test positive for screened condition(s) receive appropriate diagnosis and treatment and that their parents receive genetic counseling • Promote genetic services, public awareness, and education concerning genetic conditions
History of Newborn Screeningin Indiana • 1965: PKU only condition included in newborn screen • 1978: Hypothyroidism added • 1985: Galactosemia, homocystinuria, maple syrup urine disease (MSUD), and hemoglobinopathies added • 1999: Biotinidase deficiency and congenital adrenal hyperplasia added • 2003: Screening further expanded to include disorders detected by tandem mass spectrometry (MS/MS) • 2007: Cystic fibrosis was added to the panel • Currently, all infants born in Indiana are screened for 46 conditions (including hearing loss)
Indiana’s Newborn Screen • Two parts: • Heel Stick Screening • Includes Sickle Cell Program & Cystic Fibrosis Program • Also includes follow-up for metabolic and endocrine conditions on newborn screening panel • Early Hearing Detection and Intervention (EHDI) • Includes Universal Newborn Hearing Screen
Part I Heel Stick Screening
Heel Stick Screening • Performed on a blood specimen taken from the heel of an infant shortly after birth • Used to screen for certain genetic conditions • Metabolic conditions • Endocrine conditions • Cystic fibrosis
Tandem Mass Spectrometry (MS/MS) • Analytical technique that separates & detects protein ions • Enables newborn screening labs to quickly & efficiently detect many conditions in a single process through use of dried blood spot specimens • Disorders detected by MS/MS: • Fatty acid oxidation disorders • Interfere with body’s ability to turn fat into energy • Organic acid disorders • Inability to break down certain amino acids & their metabolites • Other amino acid disorders (including tyrosinemia & urea cycle disorders)
Newborn Screening Log • All birthing facilities should maintain a Newborn Screening Log which documents the following information for all infants: • Specimen collection date • Specimen submission date • Date NBS results were received • Results of NBS
Heel Stick Procedure • NOTE:The following procedures are modified from the heel-stick procedures slides provided by the New York State Department of Health
Heel Stick ProcedureStep 1 • Equipment: • Sterile lancet with tip appropriately 2.0 mm - sterile alcohol prep • Sterile gauze pads • Soft cloth • Blood spot card • Gloves
Heel Stick ProcedureStep 2 • Complete ALL information on blood spot card. • Do not contaminate filter paper circles by allowing the circles to come into contact with spillage or by touching before or after blood collection.
Heel Stick ProcedureStep 3 • Hatched areas (arrows) indicate safe areas for puncture site.
Heel Stick ProcedureStep 4 • Warm site with soft cloth moistened with warm water (up to 41o C) for 3 – 5 minutes.
Heel Stick ProcedureStep 5 • Cleanse site with alcohol prep. • Wipe DRY with sterile gauze pad.
Heel Stick Procedure Step 6 • Puncture heel. • Wipe away first blood drop with sterile gauze pad. • Allow another LARGE blood drop to form.
Heel Stick Procedure Step 7 • Lightly touch filter paper to LARGE blood drop. • Allow blood to soak through and completely fill circle with SINGLE application of LARGE blood drop. • To enhance blood flow, VERY GENTLY apply intermittent pressure to area surrounding the puncture site). • Apply blood to one side of filter paper only.
Heel Stick Procedure Step 8 • Fill remaining circles in the same manner as step 7, with successive blood drops. • If blood flow is diminished, repeat steps 5 through 7. • Provide care to the skin puncture site.
Heel Stick ProcedureStep 9 • Dry blood spots on a dry, clean, flat, non-absorbent surface for a minimum of four (4) hours.
Heel Stick Procedure Step 10 • Mail completed blood spot card to IU Newborn Screening Lab within 24 hours of collection.
Heel Stick Procedure NOTE: • Use of capillary tubes to collect heel stick specimens is NOT recommended or included as part of Indiana’s protocols
Valid Heel Stick Specimens • A newborn screen is valid when: • The child is at least 48 hours of age • The child has been on protein feeding for at least 24 hours • The NBS blood specimen is received by the NBS laboratory within 10 days of collection
Valid Specimens • Fill all required circles. • Allow blood to soak through to other side of filter paper. • Do not layer successive drops of blood. • Avoid touching or smearing spots.
Specimen Quantity Insufficient for Testing Possible causes • Removing filter paper before blood has completely filled circle or before blood has soaked through to second side. • Applying blood to filter paper with a capillary tube. • Touching filter paper before/after blood specimen collection (with gloved/ungloved hands, lotion, powder, etc.)
Specimen Appears Scratched/Abraded Possible cause • Applying blood with capillary tube or other device.
Specimen Not Dry Before Mailing Possible cause • Mailing specimen without drying for at least four (4) hours.
Specimen Appears Clotted or Layered Possible causes • Touching same circle on filter paper to blood drop numerous times. • Filling circle on both sides (front & back) of filter paper.
Possible Results of NBS • Normal • All values fall within normal range • Invalid screen • Specimen does not meet criteria for valid screen • Specimen > 10 days old • QNS (quantity not sufficient) • Abnormal result(s) • Result(s) fall outside of normal range, but are not presumptive positive • Additional testing may be required to confirm result(s) • Presumptive positive result(s) • Result(s) are outside the range of normal values and suggest presence of NBS condition • Additional testing may be required to confirm result(s)
Heel Stick Follow-Up Guidelines(NICU Patients) *NOTE: If discharge occurs within 6 days of 2nd or 3rd specimen, no specimen is required at discharge. Implemented October 1, 2007
NICU Specimens • For presumptive positive / abnormal NBS results for any specimen drawn from a baby in the NICU, follow-up should be performed per guidelines for non-NICU patients • Abnormal: Collect repeat NBS specimen within 5 business days • Presumptive positive: Collect additional specimen within 48 hours, as requested by NBS lab • Exception: congenital hypothyroidism • Babies in the NICU are at increased risk for developing delayed hypothyroidism due to the immaturity of their endocrine systems • Routine rescreening should be performed for all NICU babies per NICU guidelines • Additional heel stick specimens used to check for development of delayed hypothyroidism
Reporting to ISDH – Heel Stick • Birthing facilities should complete & submit the Monthly Summary Report (MSR) to ISDH • MSRs are due by the 15th of the following month • For example, January’s MSR is due before February 15th • Completed MSRs should include the following: • Cover sheet – Contact information & statistics • Heel Stick Exception Reporting Form (2 PAGES) • PAGE 1: infant data (includes transfer & exception codes) • PAGE 2: mother & PCP data • Attach copy of signed Religious Waiver if parents refused NBS based on religious reasons
MSR – Heel Stick Exception Reporting Form, PAGE 1 (infant data)
MSR – Heel Stick Exception Reporting Form, PAGE 1 (cont.) • A few notes: • Each infant reported as an exception MUST have a transfer code AND an exception code • Children born at the end of a month, who are screened at the correct time, do NOT need to be reported as exceptions anymore • Formerly “Initial Screen Next Month” exceptions • Birthing facilities are responsible for notifying ISDH NBS Program IMMEDIATELY by phone if a child is discharged without an initial NBS
MSR – Heel Stick Exception Reporting Form, PAGE 2 (mother & PCP data)
Indiana Newborn Screening Tracking & Education Program (INSTEP) • ISDH won a $1.2 million, 3-year federal grant from HRSA in September 2009 • Funding from this grant used to develop INSTEP • Includes web-based INSTEP application • Used by birthing facilities, health care providers, PHNs, & ISDH staff to data related to NBS and follow-up
INSTEP (cont.) 2011 INSTEP MSR trainings • March 22nd, Parkview Hospital (Fort Wayne) • April 14th, Columbus Regional Hospital (Columbus) • May (TBD), Porter Hospital (Valparaiso) • September 22nd, Deaconess Hospital (Evansville) • October (TBD), Indianapolis • Watch your e-mail for more information!
INSTEP (cont.) IMPORTANT! • The MSR form changed to match the information requested in INSTEP • New MSR form was distributed to all birthing facilities via e-mail in November 2010 • All birthing facilities required to use new MSR form beginning December 2010
