Parent’s Perspective
“Over the eleven years since I started C.H.I.N., hardly a day goes by when I do not hear from a distraught
parent whose child was not diagnosed at birth, leading to tragic or serious life-long consequences.”
Mona Barmash, President of Children’s Heart Information Network
JCCHD Meeting, Fall 2007

Learning Objectives
♥ Identify need for screening for CHD in the nursery
♥ Discuss evidence-based recommendations for implementing screening in community hospitals
♥ Discuss efforts for dissemination on state or national levels
♥ Recognize the public health benefit of a population-based approach to best practice
www.childrensnational.org
A Question for the Group
Physical examination in the newborn nursery accurately detects critical
congenital heart disease?
a. TRUE
b. FALSE
www.childrensnational.org
Transitional Circulation
♥ Circulatory changes include:
- Increase in systemic vascular resistance
- Decrease in pulmonary vascular resistance
- Increase in left atrial pressure
- Closure of ductus arteriosus & foramen ovale
- Increase in left ventricular stroke volume
♥ Autonomic changes include:
- Hypersympathetic state

Screening Principles
♥ Screening valuable if:– incidence is sufficient in the population
– therapy provided before onset of clinical manifestations results in an improved outcome
– screening identifies disease before symptoms
– test has acceptable sensitivity and false positive rates
– cost effective
Wilson and Junger WHO 1968 Public Health Paper

Newborns with CHD
♥ Congenital Heart Disease affects 5-10/1000 LB– the most common birth
defect
– incidence varies based
upon inclusion criteria
– 4/1000 require Rx
in the first year of lifeHoffman JACC 39:2002
www.childrensnational.org
Newborns with CHD
♥ CHD has significant morbidity/mortality
– nearly 40% deaths from congenital anomalies
– majority of deaths
occur among infants
Boneva Circ 103:2001
www.childrensnational.org
Newborns with CHD
♥ Timely recognition in NB period is critical– Prenatal diagnosis made in only 23% of pregnancies and
only 11% of live births
– In 39% (7/18) diagnosis only made at subsequent admission

Current Diagnosis/Detection
♥ Newborn screening programs exist
– cyanosis, auscultation, palpation of pulses
– results mostly unknown but detection may be < 50%
Wren in Arch Dis Child Fetal Neonatal Ed 80:1999
♥ 1 % Dead Pre-detection
♥ Only 44% had detection by PE alone

Pulse Oximetry Screening
Koppel Pediatrics 111:2003

Pulse Oximetry as Screening Method
♥ Pulse oximetry measures the amount of oxygen in the blood
♥ Non-invasive and painless test

Why have we not done anything?
♥ Cardiologists have not been fully supportive of screening.
♥ Advocacy necessary.

AHA/AAP Scientific Statement
♥ Purpose: Address evidence on the routine use of pulse oximetry in newborns to detect critical CHD
♥ Methods: Medline database searches from 1966-2008
♥ Analysis of pooled studies performed after 24 h life– Sensitivity 69.6%, PPV 47%– False positive screens requiring further testing 0.035%
www.childrensnational.org
AHA/AAP Scientific Statement
♥Conclusions:
-Critical CHD is not detected in some infants
-Failure to detect is associated with significant morbidity and occasional mortality
-Pulse oximetry may detect critical CHD
-Routine pulse oximetry after 24 hours incurs low cost and risk of harm
-Further studies in larger populations necessary across a broad range of newborn
delivery systems to decide whether this should be standard of care

♥ To address questions regarding implementation, partnership established Holy Cross Hospital in Silver Spring, Maryland, one of the areas busiest birthing facilities
♥ Evidence-based research protocol to examine implementation in community nurseries
♥ Enrollment of mothers and infants began January 12, 2009
Research Efforts Surrounding Implementation
www.childrensnational.org
Study Aims:
1. Determine if a pulse oximetry screening program for the detection of critical congenital heart disease can be implemented in a large community hospital.
2. Identify obstacles encountered while performing pulse oximetry screening methods of suggested screening program design..
3. Determine number of participants with critical congenital heart disease identified by suggested program design..
4. Evaluate the effectiveness of the maternal consent process for pulse oximetry screening of infants.

A Question for the Group
Implementing a screening program requires how many additional staff
positions?
a. 0
b. 1
c. 2
d. 3
www.childrensnational.org
Overview of Methods:
♥ Pox on right arm and right foot following 24 hours of age, in conjunction with PKU screen
♥ “Passing” Pulse Ox Sats – Greater than 95%
♥ “Referring” Pulse Ox Sats – Equal to or less than 95%, 3% Differential between RH and RF
- Pediatrician alerted. Echo and Cardiology Consult Recommended
♥ Tracking of enrolled infants actually screened, time of screening, obstacles to screening, maternal recall of consent
Research Efforts Surrounding Implementation
www.childrensnational.org
Preliminary Findings from Research Efforts:
• 6,705 infant participants enrolled
• 6,489infant participants (97%) actually screened
• 3 False Positives
• 2 Inconclusive – Primary MD did not order additional tests
• 4 True Positive
– 2 TP for Critical CHD (SVC draining to LA, Dextrocardia with Situs Inversus)
– 2 TP for Non-Critical CHD (Dilated Aorta, ASD)
• Screening time = Approximately 4 minutes per participant
• Average Pox Sat = 98-99%
• Obstacles to screening: High Volume Days, Early Discharges
• Approximately 90% of mothers are able to recall that they agreed to participate in the study and that their infant was screened

Congenital Heart Disease Screening Program
MissionThe Congenital Heart Disease Screening Program values
the early diagnosis of congenital heart disease in newborns prior to the clinical deterioration of affected infants. The program promotes early detection through the use of pulse oximetry following 24 hours of age and
prior to discharge from the newborn nursery. The program values the importance of the screening of all
healthy newborns for congenital heart disease.
VisionAll infants with critical congenital heart disease are
detected before leaving the newborn nursery.

Public Health Parable
A man is standing by a river when he hears a cry for help. He
sees someone struggling in the water, on the verge of drowning.
Being an expert swimmer, he jumps in and rescues the victim.
Before he has time to rejoice in his success, however, he sees
someone else floating by, also crying for help. As soon as he
rescues this person, he discovers a third....then a fourth and a
fifth. More and more victims float by, taxing his swimming
stamina. Finally he walks away. When asked where he is
going, he replies, "I'm going up the river to try to stop people
from falling in."

Building in Child Health Advocacy
• Why Advocacy?
– Community Benefit
– Corporate Compliance/Citizenship
• Collaborative Implementation
www.childrensnational.org
Broad Definition: Child Advocacy
• Engagement in activities that seek to compensate for the fundamental vulnerability of children.

while applying professional expertise and leadership to support efforts on individual (patient or family), community, and legislative/policy levels, which result in the improved quality of life for individuals, families and communities.”
