Abstract
OBJECTIVE This study aimed to compare oximetry data (pre- and postductal oxygen saturation [SpO2], pre- and postductal pulsatility index [PI]) in healthy newborns (≥35 weeks' gestational age) to infants who have critical congenital heart disease (CCHD). STUDY DESIGN This is a retrospective analysis of data obtained from electronic medical records, recorded as part of routine pulse oximetry screening (POS) for CCHD in infants born between the years 2013 and 2020. Testing was performed at 24 ± 2 hours of life. Data were analyzed to detect differences in pre- and postductal SpO2 and pre- and postductal PI in healthy newborns compared with infants who have CCHD. Newborns were excluded from analysis if they: (1) had a prenatal diagnosis of CCHD in the medical record, (2) had previously been admitted to the neonatal intensive care unit, or (3) had failed POS but were found no CCHD by diagnostic echocardiography. RESULTS A total of 88,754 healthy newborns had received POS between the years 2013 and 2020. Of the 88,736 newborn records available for analysis,18 newborns were diagnosed with CCHD. Eight were identified by POS before discharge and 10 were diagnosed after discharge. Infants diagnosed with CCHD by POS had lower pre- and postductal SpO2 compared with normal infants. Their postductal PI was significantly lower. Infants who had CCHD that was not identified by POS had similar pre- and postductal SpO2 values, but their postductal PI was lower. Using a postductal PI cutoff of 1.21 had a receiver operating curve of area under the curve 0.77 (95% confidence interval: 0.672, 0.869) with 74% sensitivity and 61% specificity. CONCLUSION In our large cohort of infants born in San Diego County, the postductal PI is lower in infants with CCHD. Given that PI is routinely displayed on every pulse oximeter and the high morbidity of missed CCHD, PI should be incorporated into routine CCHD screening. KEY POINTS · Postductal PI is lower in newborn who presented later with congenital heart disease.. · Postductal PI cut-off of 1.21 may help practitioners determine if a newborn is at risk for CCHD.. · This large cohort study demonstrates that a low PI can detect additional CCHD cases..

Abstract
INTRODUCTION Timely identification of at-risk neonates (ARNs) in the community is essential to reduce mortality in low-resource settings. Tools such as American Academy of Pediatrics pulse oximetry (POx) and WHO Young Infants Clinical Signs (WHOS) have high specificity but low sensitivity to identify ARNs. Our aim was assessing the value of POx and WHOS independently, in combination and with machine learning (ML) from clinical features, to detect ARNs in a low/middle-income country. METHODS This prospective cohort study was conducted in a periurban community in Pakistan. Eligible live births were screened using WHOS and POx along with clinical information regarding pregnancy and delivery. The enrolled neonates were followed for 4 weeks of life to assess the vital status. The predictive value to identify ARNs, of POx, WHOS and an ML model using maternal and neonatal clinical features, was assessed. RESULTS Of 1336 neonates, 68 (5%) had adverse outcomes, that is, sepsis (n=40, 59%), critical congenital heart disease (n=2, 3%), severe persistent pulmonary hypertension (n=1), hospitalisation (n=8, 12%) and death (n=17, 25%) assessed at 4 weeks of life. Specificity of POx and WHOS to independently identify ARNs was 99%, with sensitivity of 19% and 63%,respectively. Combining both improved sensitivity to 70%, keeping specificity at 98%. An ML model using clinical variables had 44% specificity and 76% sensitivity. A staged assessment, where WHOS, POx and ML are sequentially used for triage, increased sensitivity to 85%, keeping specificity 75%. Using ML (when WHOS and POx negative) for community follow-up detected the majority of ARNs. CONCLUSION Classic screening, combined with ML, can help maximise identifying ARNs and could be embedded in low-resource clinical settings, thereby improving outcome. Sequential use of classic assessment and clinical ML identifies the most ARNs in the community, still optimising follow-up clinical care.

Abstract
BACKGROUND Prenatal diagnosis and planned peri-partum care is an unexplored concept for care of neonates with critical CHDs in low-middle-income countries. OBJECTIVE To report the impact of prenatal diagnosis on pre-operative status in neonates with critical CHD. METHODS Prospective observational study (January 2017-June 2018) in tertiary paediatric cardiac facility in Kerala, India. Neonates (<28 days) with critical CHDs needing cardiac interventions were included. Pre-term infants (<35 weeks) and those without intention to treat were excluded. Patients were grouped into those with prenatal diagnosis and diagnosis after birth. Main outcome measure was pre-operative clinical status. RESULTS Total 119 neonates included; 39 (32.8%) had prenatal diagnosis. Eighty infants (67%) underwent surgery while 32 (27%) needed catheter-based interventions. Pre-operative status was significantly better in prenatal group; California modification of transport risk index of physiological stability (Ca-TRIPS) score: median 6 (0-42) versus 8 (0-64); p < 0.001; pre-operative assessment of cardiac and haemodynamic status (PRACHS) score: median 1 (0-4) versus 3 (0-10), p < 0.001. Age at cardiac procedure was earlier in prenatal group (median 5 (1-26) versus 7 (1-43) days; p = 0.02). Mortality occurred in 12 patients (10%), with 3 post-operative deaths (2.5%). Pre-operative mortality was higher in postnatal group (10% versus 2.6%; p = 0.2) of which seven (6%) died due to suboptimal pre-operative status precluding surgery. CONCLUSION Prenatal diagnosis and planned peri-partum care had a significant impact on the pre-operative status in neonates with critical CHD in a low-resource setting.

Abstract
BACKGROUND Approximately 25% of congenital heart diseases (CHD) are estimated to be critical and require an intervention. In this study, we aimed to investigate the additional value of peripheral perfusion index (PPI) measurements to pulse oximetry screening for critical CHD (CCHD). METHODS Infants born at Ege University Hospital between May 2013 and September 2015 were prospectively included in the study. In addition to physical examination, pre- and postductal oxygen saturations and PPI values were measured with a new generation pulse oximeter before discharge from the hospital. RESULTS A total of 3175 newborns (33 with an antenatal diagnosis of CCHD) were included in the study. With the combination of physical examination, pulse oximetry screening and peripheral perfusion index (PPI) measurements, all newborns with CCHD were detected in our study including three infants without an antenatal diagnosis in whom pulse oximetry screening was negative. CONCLUSION PPI measurements may be valuable for early detection of obstructive left heart lesions where pulse oximetry screening has limitations in diagnosis.

Abstract
BACKGROUND Pulse oximetry screening is a highly accurate tool for the early detection of critical congenital heart disease (CCHD) in newborn infants. As the technique is simple, noninvasive, and inexpensive, it has potentially significant benefits for developing countries. The aim of this study is to provide information for future clinical and health policy decisions by assessing the cost-effectiveness of CCHD screening in China. METHODS AND FINDINGS We developed a cohort model to evaluate the cost-effectiveness of screening all Chinese newborns annually using 3 possible screening options compared to no intervention: pulse oximetry alone, clinical assessment alone, and pulse oximetry as an adjunct to clinical assessment. We calculated the incremental cost per averted disability-adjusted life years (DALYs) in 2015 international dollars to measure cost-effectiveness. One-way sensitivity analysis and multivariate probabilistic sensitivity analysis were performed to test the robustness of the model. Of the three screening options, we found that clinical assessment is the most cost-effective strategy compared to no intervention with an incremental cost-effectiveness ratio (ICER) of Int$5,728/DALY, while pulse oximetry plus clinical assessment with the highest ICER yielded the best health outcomes. Sensitivity analysis showed that when the treatment rate increased up to 57.5%, pulse oximetry plus clinical assessment showed the best expected values among the three screening options. CONCLUSION In China, for neonatal screening for CCHD at the national level, clinical assessment was a very cost-effective preliminary choice and pulse oximetry plus clinical assessment was worth considering for the long term. Improvement in accessibility to treatment is crucial to expand the potential health benefits of screening.

Abstract
OBJECTIVE Screening for critical congenital heart disease (CCHD) using pulse oximetry has been endorsed by the American Academy of Pediatrics and the American Heart Association. The recommended screening requires two saturation readings. We sought to determine the incidence of undetected CCHD in Tennessee for the 2 years following implementation of an algorithm that assigned an immediate pass to a single lower extremity saturation of 97% or higher. STUDY DESIGN State Genetic Screening records and reports of missed cases from the Tennessee Initiative for Perinatal Quality Care were used to determine if CCHD cases were missed by the new screening algorithm. RESULT During the study, 232 infants failed the screen with 51 or 22% true positives, 13 infants had undetected CCHD (10 coarctations, 2 anomalous veins and 1 Tetralogy of Fallot). CONCLUSION This approach eliminated over 150 000 pulse oximetry determinations in Tennessee without affecting the ability of pulse oximetry to detect CCHD before discharge.

Abstract
Introduction: Congenital heart defects are the most common congenital anomalies and occur with an incidence from 0.8 to 1% per 1000 live births. In recent years, the pulse oximetry has become a strong candidate for detecting cyanogen congenital heart defects and in combination with routine clinical exam can improve diagnostic of congenital heart diseases. Objective: To apply the modern algorithm for early detection of congenital heart defects in order to improve the diagnosis in the neonatal period. Patients and Methods: This was a prospective study that included children born in Bihac Cantonal Hospital during 2012. The diagnostic algorithm included a clinical examination of the newborn, measuring of transcutaneous oxygen saturation with the pulse oximeter between 24 and 48 hours of life, and, in some cases, additional tests (cardiac ultrasound). Results: A total of 1,865 children were examined. The application of diagnostic protocol identified the existence of congenital heart defects in 29 children. In re-evaluating the auscultator and ultrasound findings, we identified congenital heart defects in 19 children. Conclusion: The application of the modern algorithm for early detection of congenital heart diseases in the neonatal period can significantly improve the making of diagnosis of these anomalies. The concept is simple, inexpensive and applicable in most maternity wards.

Abstract
Critical congenital heart disease (CCHD) is a major cause of infant death and morbidity worldwide. An early diagnosis and timely intervention can significantly reduce the likelihood of an adverse outcome. However, studies from the United States and other developed countries have shown that as many as 30%–50% of infants with CCHD are discharged after birth without being identified. This diagnostic gap is likely to be even higher in low-resource countries. Several large randomized trials have shown that the use of universal pulse-oximetry screening (POS) at the time of discharge from birth hospital can help in early diagnosis of these infants. The objective of this review is to share data to show that the use of POS for early detection of CCHD meets the criteria necessary for inclusion to the universal newborn screening panel and could be adopted worldwide.

Abstract
This article presents an approach for identification of infants with congenital heart disorders. These disorders are difficult to diagnose because of the complexity and variety of cardiac malformations; additionally presentation can be complicated by age-dependent physiology. By compiling data from the history and the physical examination, the emergency physician can identify lesion category and initiate stabilization procedures. Critical congenital cardiac lesions can be classified as left-sided obstructive ductal dependent, right-sided obstructive ductal dependent, and shunting or mixing. The simplified approach categorizes infants with these lesions respectively as "pink," "blue," or "gray." The emergency provider can provide life-saving stabilization until specialized care can be obtained.

Abstract
Pulse oximetry (POx) screening for critical congenital heart disease (CCHD) in neonates is less effective in identifying aortic arch obstruction than in detecting other forms of CCHD. This study was performed to assess the use of neonatal blood pressure (BP) screening to detect CCHD. A retrospective review of BP and POx measurements performed at the age of 24 h or before discharge in asymptomatic term neonates was undertaken. The charts of infants readmitted younger than 30 days with a diagnosis of CCHD also were reviewed to identify infants with a missed diagnosis. The screening process was completed for 10,012 of 10,436 infants. Because of an abnormal initial result, 164 neonates required a repeat screening (139 due to abnormal BP). A total of 12 infants failed the BP screening component, and 1 infant failed both the BP and Pox components. The average final right arm-to-leg BP gradient was 25 mmHg in these 13 babies. For nine infants, CCHD was excluded by echocardiography. Three patients were normal at their 1-year well-child exam, and one patient was lost to follow-up evaluation. No infants were identified who had been discharged home with a missed diagnosis of CCHD. Neonatal BP screening to detect CCHD was responsible for more inappropriately performed screenings, repeated screenings, and screening failures than the POx component of the screening protocol and had a highest possible positive predictive value of 1 in 13. These data suggests that BP screening at the time of routine newborn hospital discharge is of limited value in the detection of unrecognized CCHD.

Abstract
AIM Despite there being evidence that pulse oximetry screening is better than clinical examination alone in early detection of CHD, implementation has been slow. The aim of this paper was to evaluate the practice after its implementation into routine care at Royal Prince Alfred Hospital in 2008. METHODS A single pulse oximetry measurement was incorporated in the routine discharge newborn examination or, with early discharge, as a part of the Midwife Discharge Support Programme. An oxygen saturation level greater than or equal to 95% was considered normal, and a level less than 95%, confirmed on a repeat measure, triggered a review and examination by a consultant neonatal paediatrician. The saturation levels were recorded in the hospital database. Ascertainment of major CHD requiring surgery in the first 12 months was performed by searching the cardiac surgery database of the Heart Centre for Children. RESULTS A total of 18 801 babies were screened over a 42-month period. Of these, four babies with major CHD were diagnosed prior to discharge with the main clinical alert resulting from routine pulse oximetry screening (true positive). Of the 11 cases with saturation <95% but no CHD (false positive cases), six had respiratory pathology. One baby with normal saturation level needed surgery in the first year for a large ventricular septal defect (false negative). The false positive rate of pulse oximetry screening for CHD was 0.13% with sensitivity 80%, specificity of 99.8%, a positive predictive value of 13.3% and a negative predictive value of 99.9%. Nine additional echocardiogram were required over 42 months. CONCLUSIONS These post-implementation data confirm that pulse oximetry screening increases early diagnosis of major CHD as well as other important pathology with a very low false positive rate and minimal requirement for extra echocardiograms. Pulse oximetry screening of apparently well newborns should become a standard of care.

Abstract
BACKGROUND Delayed diagnosis of critical congenital heart disease (CCHD) in neonates increases morbidity and mortality. The use of pulse oximetry screening is recommended to increase detection of these conditions. The contribution of pulse oximetry in a tertiary-care birthing center may be different from at other sites. METHODS We analyzed CCHD pulse oximetry screening for newborns ≥ 35 weeks' gestation born at Brigham and Women's Hospital and cared for in the well-infant nursery during 2013. We identified patients with prenatal diagnosis of CCHD. We also identified infants born at other medical centers who were transferred to Boston Children's Hospital for CCHD and determined if the condition was diagnosed prenatally. RESULTS Of 6838 infants with complete pulse oximetry data, 6803 (99.5%) passed the first screening. One infant failed all 3 screenings and had the only echocardiogram prompted by screening that showed persistent pulmonary hypertension. There was 1 false-negative screening in an infant diagnosed with interrupted aortic arch. Of 112 infants born at Brigham and Women's Hospital with CCHD, 111 had a prenatal diagnosis, and none was initially diagnosed by pulse oximetry. Of 81 infants transferred to Boston Children's Hospital from other medical centers with CCHD, 35% were diagnosed prenatally. CONCLUSIONS In our tertiary-care setting, pulse oximetry did not detect an infant with CCHD because of effective prenatal echocardiography screening. Pulse oximetry will detect more infants in settings with a lower prenatal diagnosis rate. Improving training in complete fetal echocardiography scans should also improve timely diagnosis of CCHD.

Abstract
BACKGROUND AND OBJECTIVE Newborn pulse oximetry screening is recommended to promote early referral of neonates with critical congenital heart disease (CCHD) and reduce mortality; however, the impact of late referral on mortality is not well defined. The purpose of this population-based study was to describe the association between timing of referral to a cardiac center and mortality in 2360 liveborn neonates with CCHD. METHODS Neonates with CCHD born before pulse oximetry screening (1996-2007) were selected from the Texas Birth Defects Registry and linked to state birth and death records. Age at referral was ascertained from date of first cardiac procedure at a cardiac center. Logistic and Cox proportional hazards regression models were used to estimate factors associated with late referral and mortality; the Kaplan-Meier method was used to estimate 3-month survival. RESULTS Median age at referral was 1 day (25th-75th percentile: 0-6 days). Overall, 27.5% (649 of 2360) were referred after age 4 days and 7.5% (178 of 2360) had no record of referral. Neonatal mortality was 18.1% (277 of 1533) for those referred at 0 to 4 days of age, 9.0% (34 of 379) for those referred at 5 to 27 days of age, and 38.8% (69 of 178) for those with no referral. No improvement in age at referral was found across the 2 eras within 1996-2007. CONCLUSIONS A significant proportion of neonates with CCHD experienced late or no referral to cardiac specialty centers, accounting for a significant number of the deaths. Future population-based studies are needed to determine the benefit of pulse oximetry screening on mortality and morbidity.

Abstract
OBJECTIVES To describe current practice and clarify provider opinion in the US with regard to newborn pulse oximetry screening (NPOx) for critical congenital heart disease. STUDY DESIGN An internet-based questionnaire was forwarded to general pediatricians, neonatologists, and family medicine physicians. Physicians were surveyed regarding involvement in newborn medicine, knowledge of NPOx recommendations, and opinions regarding screening. NPOx protocol specifics were also queried. RESULTS Survey responses (n = 481) were received with 349 respondents involved in newborn medicine. Forty-nine percent (95% CI 44%-54%) of those involved in newborn medicine practice at a hospital with a NPOx protocol. Sixty-six percent of providers endorsed it as an effective tool, 20% required more education, 11% questioned its sensitivity, and 3% had no opinion. Sixty-five percent of providers were aware of recent state legislation mandating its use and 46% reported awareness of the addition of NPOx to the Recommended Uniform Screening Panel. Eighty-four percent of providers who practice at a hospital without a NPOx protocol were interested in its implementation. NPOx protocols varied and were not uniform with differences in time of test, location of probe, and values considered positive. CONCLUSIONS NPOx has grown in its prevalence and acceptance in clinical practice, yet is far from universal in its application and design despite the recent American Academy of Pediatrics endorsement and its addition to the Recommended Uniform Screening Panel. The majority of physicians involved in newborn medicine deemed it an effective tool.

Abstract
OBJECTIVE Critical congenital heart disease (CCHD) was recently added to the U.S. Recommended Uniform Screening Panel for newborns. This evaluation aimed to estimate screening time and hospital cost per newborn screened for CCHD using pulse oximetry as part of a public health economic assessment of CCHD screening. METHODS A cost survey and time and motion study were conducted in well-newborn and special/intensive care nurseries in a random sample of seven birthing hospitals in New Jersey, where the state legislature mandated CCHD screening in 2011. The sample was stratified by hospital facility level, hospital birth census, and geographic location. At the time of the evaluation, all hospitals had conducted CCHD screening for at least four months. RESULTS Mean screening time per newborn was 9.1 (standard deviation = 3.4) minutes. Hospitals' total mean estimated cost per newborn screened was $14.19 (in 2011 U.S. dollars), consisting of $7.36 in labor costs and $6.83 in equipment and supply costs. CONCLUSIONS This federal agency-state health department collaborative assessment is the first state-level analysis of time and hospital costs for CCHD screening using pulse oximetry conducted in the U.S. Hospitals' cost per newborn screened for CCHD with pulse oximetry is comparable with cost estimates of existing newborn screening tests. Hospitals' equipment costs varied substantially based on the pulse oximetry technology employed, with lower costs among hospitals that used reusable screening sensors. In combination with estimates of screening accuracy, effectiveness, and avoided costs, information from this evaluation suggests that CCHD screening is cost-effective.

Abstract
Screening for critical congenital heart disease (CCHD) using pulse oximetry has been endorsed by the American Academy of Pediatrics and the American Heart Association. We sought to determine the incidence of undetected CCHD in Tennessee and the diagnostic gap of CCHD in Middle Tennessee prior to screening implementation. The Tennessee Initiative for Perinatal Quality Care (TIPQC) Undetected CCHD Registry is a quality improvement initiative established to identify neonates discharged from the nursery with undetected CCHD. The TIPQC database was queried and a simultaneous review of all neonates with CCHD in the Middle Tennessee region was performed to define the incidence and identify the pre-screen diagnostic gap of undetected CCHD at the time of hospital discharge. In 2011, of 79,462 live births in Tennessee, 12 newborns had undiagnosed CCHD (incidence 15 per 100,000; 95 % CI 9-26 per 100,000). Nine of 12 (75 %) had coarctation of the aorta (CoA). There were no deaths due to undiagnosed CCHD. In the Middle Tennessee region, 6 of 45 neonates with CCHD were missed, for a diagnostic gap of 13 % (95 % CI 6-26 %). Prior to implementation of CCHD screening using pulse oximetry, 12 Tennessee neonates with CCHD were missed by prenatal ultrasound and newborn examination. CoA was the most common lesion missed and is also the CCHD most likely to be missed despite addition of screening using pulse oximetry. Continued evaluation of the diagnostic gap with particular attention to missed diagnoses of CoA should accompany institution of CCHD screening programs.

Abstract
INTRODUCTION Babies with cardiac anomalies are often asymptomatic at birth, and many remain undetected despite routine newborn examination. We retrospectively assessed the effect of routine pulse oximetry in detection of such anomalies from a hospital birth population of 31 946 babies born between 1 April 1999 and 31 March 2009. METHOD 29 925 babies who were not admitted to the neonatal unit at birth underwent postductal oxygen saturation measurement before discharge. If saturation was below 95% an examination was performed. If this was abnormal or saturation remained low, an echocardiogram was performed. All babies with cardiac anomaly diagnosed before 1-year were identified from the region's fetal abnormality database. RESULTS Critical anomalies affected 27 infants (1 in 1180); 10 identified prenatally, 2 after echocardiogram was performed because of other anomalies, 2 in preterm infants, 2 when symptomatic before screening, 5 by oximetry screening, 1 when symptomatic in hospital after a normal screen and 5 after discharge home. Serious anomalies affected 50 infants (1 in 640); 8 identified antenatally, 7 because of other anomalies, 3 in the neonatal unit, 5 by pulse oximetry screening, 11 by routine newborn examination, and 16 after discharge home. CONCLUSIONS Routine pulse oximetry aided detection of 5/27 of critical and 5/50 of serious anomalies in this sample, but did not prevent five babies with critical and 15 with serious anomalies being discharged undiagnosed. Results from screening over 250 000 babies have now been published, but this total includes only 49 babies with transposition, and even smaller numbers of rarer anomalies.

Abstract
Routine pulse oximetry screening (POS) performed on asymptomatic newborns after 24 hours of life, but before hospital discharge, may detect critical congenital heart defects (cCHD) when used as an adjunct to physical examination. Timely identification of this small percentage of newborns prompts early intervention and improves outcomes. New-generation, highly accurate pulse oximeters provide a simple, low-risk, low-cost tool to improve detection of potentially lethal cardiac lesions. The purpose of this study was to develop, implement, and test the utility of a nurse-driven algorithm that would support and serve as a guide for detection of cCHD in asymptomatic newborns using POS prior to discharge home from the hospital. Results showed that this collaborative protocol was easily implemented in a community hospital. The universal algorithm enhances POS and clinical examination to identify asymptomatic infants with undiagnosed cCHD prior to discharge from the hospital.

Abstract
OBJECTIVE Pulse oximetry screening of asymptomatic newborns is suggested as a life-saving procedure for the timely detection of critical congenital heart disease (CHD) in asymptomatic newborns. We evaluated this screening and report cases that demonstrate problems with screening in a non-research setting. STUDY DESIGN An elective state-directed public health screening program was evaluated in Middle Tennessee; 14 564 infants were screened after 24 h of age and before discharge. The screening was performed in a non-research setting by nurses at the local hospitals. A parallel investigation of the methods and timing of diagnosis in Middle Tennessee revealed a surprisingly high incidence of antenatal diagnosis (66%). RESULT Using a saturation value of 94% as the defined normal, the positive predictive value was less than 1%, with 112 infants having a false positive case and 1 having a true positive case identified (incidence 1/34 775). The one true positive case was not referred for evaluation. One false-positive case resulted in a costly referral and hospitalization. Antenatal diagnosis when combined with physical examination detected 43 of 44 infants with critical CHD during the year-long evaluation. CONCLUSION Before universal screening can be implemented, a system of care must be defined to address the educational and referral issues raised by this report.

Abstract
BACKGROUND The purpose of this statement is to address the state of evidence on the routine use of pulse oximetry in newborns to detect critical congenital heart disease (CCHD). METHODS AND RESULTS A writing group appointed by the American Heart Association and the American Academy of Pediatrics reviewed the available literature addressing current detection methods for CCHD, burden of missed and/or delayed diagnosis of CCHD, rationale of oximetry screening, and clinical studies of oximetry in otherwise asymptomatic newborns. MEDLINE database searches from 1966 to 2008 were done for English-language papers using the following search terms: congenital heart disease, pulse oximetry, physical examination, murmur, echocardiography, fetal echocardiography, and newborn screening. The reference lists of identified papers were also searched. Published abstracts from major pediatric scientific meetings in 2006 to 2008 were also reviewed. The American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. In an analysis of pooled studies of oximetry assessment performed after 24 hours of life, the estimated sensitivity for detecting CCHD was 69.6%, and the positive predictive value was 47.0%; however, sensitivity varied dramatically among studies from 0% to 100%. False-positive screens that required further evaluation occurred in only 0.035% of infants screened after 24 hours. CONCLUSIONS Currently, CCHD is not detected in some newborns until after their hospital discharge, which results in significant morbidity and occasional mortality. Furthermore, routine pulse oximetry performed on asymptomatic newborns after 24 hours of life, but before hospital discharge, may detect CCHD. Routine pulse oximetry performed after 24 hours in hospitals that have on-site pediatric cardiovascular services incurs very low cost and risk of harm. Future studies in larger populations and across a broad range of newborn delivery systems are needed to determine whether this practice should become standard of care in the routine assessment of the neonate.

Abstract
OBJECTIVE To compare strategies with and without first-day of life pulse oximetry screening to detect critical congenital heart defects (CCHDs). STUDY DESIGN Population based study including all live born infants in Norway in 2005 and 2006 (n = 116 057). Postductal (foot) arterial oxygen saturation (SpO(2)) was measured in apparently healthy newborns after transferral to the nursery, with SpO(2) < 95% as cut-off point. Out of 57 959 live births in the hospitals performing pulse oximetry screening, 50 008 (86%) were screened. RESULTS A total of 136 CCHDs (1.2 per 1000) were diagnosed, 38 (28%) of these prenatally. Of the CCHDs detected after birth, 44/50 (88%) were detected before discharge in the population offered pulse oximetry screening (25 by pulse oximetry), compared to 37/48 (77%) in the non-screened population (p = 0.15). Median times for diagnosing CCHDs in-hospital before discharge were 6 and 16 h after birth respectively (p < 0.0001). In the screened population 6/50 (12%) CCHDs were missed and recognized after discharge because of symptoms. Two of the six missed cases failed the pulse oximetry screening, but were overlooked (echocardiography not performed before discharge). If these cases had been recognized, 4/50 (8%) would have been missed compared to 11/48 (23%) in the non-screened population (p = 0.05). Of the cases missed, 14/17 (82%) had left-sided obstructive lesions. CONCLUSION First-day of life pulse oximetry screening provides early in-hospital detection of CCHDs and may reduce the number missed and diagnosed after discharge.

Abstract
BACKGROUND Controversies exist regarding the use of pulse oximetry for routine screening of newborns. This study aimed to evaluate current practices and opinions of pediatric cardiologists in relation to newborn screening for congenital heart disease (CHD) using pulse oximetry. METHODS Email invitations were sent to 1,045 pediatric cardiologists in North America. The survey was Internet based and included multiple-choice questions. Two repeat email reminders were sent after the initial invitation. RESULTS A total of 363 responses (35%) were returned. In terms of experience, 40% of the respondents had more than 20 years, 32% had 10 to 20 years, 21% had 5 to 10 years, and 6% had less than 5 years of experience. More than 90% agreed that an early diagnosis of CHD for newborns prevents morbidity and mortality. In terms of practice, 96% reported that all newborns are examined by a clinician before discharge, 29% reported that newborns get a pulse oximetry reading, and 1.4% (n = 5) reported the use of electrocardiogram. Only 58% of respondents thought that current practice is adequate for detecting significant CHD. With regard to their experience with pulse oximetry, 26% reported "too many false-positives," 21% described it as "prone to noise and artifact," and 30% viewed it as "very operator dependent." The overall support for mandated pulse oximetry screening was 55%. The support for mandate decreased with years of experience, with 76% of the supporters having less than 5 years, 58% of those having 5 to 10 years, 53% of those having 10 to 20 years, and 51% of those having more than 20 years of experience. CONCLUSIONS Pediatric cardiologists recognize that current practice is inadequate for detecting significant CHD. Slightly more than half of the pediatric cardiologists in this study supported a mandate for pulse oximetry screening, but there were many concerns, and the support decreased with increasing years of clinical experience.

Abstract
OBJECTIVE The purpose of this prospective study was to assess the feasibility and reliability of pulse oximetry screening to detect critical congenital heart defects in a newborn nursery. METHODS The study was performed in a large urban hospital with an exclusively inborn population. Stable neonates who had a gestational age of >or=35 weeks and birth weight of >or=2100 g and in whom a critical congenital heart defect was not suspected were admitted to the newborn nursery. When the 4-hour pulse oximetry reading was <96%, pulse oximetry was repeated at discharge, and when the pulse oximetry reading remained at persistently <96%, echocardiography was performed. RESULTS Of 15299 admissions to newborn nursery during the 12-month study period, 15233 (99.6%) neonates were screened with 4-hour pulse oximetry. Pulse oximetry readings were >or=96% for 14374 (94.4%) neonates; 77 were subsequently evaluated before discharge for cardiac defects on the basis of clinical examination. Seventy-six were normal, and 1 had tetralogy of Fallot with discontinuous pulmonary arteries. Pulse oximetry readings at 4 hours were <96% in 859 (5.6%); 768 were rescreened at discharge, and 767 neonates had a pulse oximetry reading at >or=96%. One neonate had persistently low pulse oximetry at discharge; echocardiography was normal. Although 3 neonates with a critical congenital heart defect had a 4-hour pulse oximetry reading of <96%, all developed signs and/or symptoms of a cardiac defect and received a diagnosis on the basis of clinical findings, not screening results. CONCLUSIONS All neonates with a critical congenital heart defect were detected clinically, and no cases of critical congenital heart defect were detected by pulse oximetry screening. These results indicate that pulse oximetry screening does not improve detection of critical congenital heart defects above and beyond clinical observation and assessment. Our findings do not support a recommendation for routine pulse oximetry screening in seemingly healthy neonates.

Abstract
Routine pulse oximetry has been studied to detect children with otherwise undiagnosed congenital heart disease prior to nursery discharge. The reported sensitivities in asymptomatic patients have been less than expected and vary widely, bringing into question the reliability of the test. The purpose of this study was to assess whether routine pulse oximetry contributes to identifying patients with critical congenital heart disease and to determine the reliability of a single pulse oximeter reading in screening asymptomatic newborn infants. Between December 26, 2003, and December 31, 2005, three hospitals in west central Florida performed a pulse oximetry routinely on all newborns at the time of discharge. Patients diagnosed with critical congenital heart disease during the study period were identified to assess whether the pulse oximetry reading initiated their diagnosis. In one hospital, the pulse oximeter data were evaluated for reliability. Downloaded data were compared to a log compiled by the nursery personnel, first without (phase 1) and then with (phase 2) their knowledge and additional training. Results were characterized as reliable, probe placed but reading not verifiable, or no evidence of probe placement. Of the 7962 infants who received oximetry testing, there were 12 postnatal diagnoses of critical congenital heart disease. None was initially identified by routine pulse oximetry. Pulse oximetry reliability improved substantially between phase 1 and phase 2 (38 v. 60%, p < 0.0001). Optimal reliability (>95%) was obtained by a nurse with a degree of LPN or higher performing an assessment of at least 360 seconds. Routine pulse oximetry was neither reliable nor an important diagnostic tool in our cohort. Important human factors (probe placement time, oximetry training, and nursing degree) impact single determination pulse oximetry reliability. With routine surveillance and quality improvement, the reliability of this test can be increased. Future studies to determine the effectiveness of pulse oximetry screening for the diagnosis of congenital heart disease in the asymptomatic newborn population must address these factors. Until such a study demonstrates acceptable sensitivity and clinical value, universal screening should not be instituted.

Abstract
OBJECTIVE Critical congenital heart disease has been proposed as a target of newborn screening. This study aimed to define the incidence and timing of significant physiologic compromise attributable to critical congenital heart disease as well as the distribution of vulnerable lesions. These descriptive parameters must be defined to evaluate the impact and feasibility of any proposed screening strategy. METHODS A retrospective cohort study of neonates who had critical congenital heart disease and were admitted to a single institution was conducted. Critical congenital heart disease was defined as congenital heart disease that required invasive intervention or resulted in death in the first 30 days of life. Significant physiologic compromise was defined by severe metabolic acidosis, seizure, cardiac arrest, or laboratory evidence of renal or hepatic injury before invasive intervention. Significant physiologic compromise was classified as potentially preventable when it occurred as a result of undiagnosed congenital heart disease after 12 hours of life. RESULTS Significant physiologic compromise occurred in 76 (15.5%) of 490 patients, and potentially preventable significant physiologic compromise occurred in 33 (6.7%) of 490 patients. Most (83%) significant physiologic compromise as a result of unrecognized congenital heart disease occurred after 12 hours of age. A total of 90.9% of cases of potentially preventable significant physiologic compromise had aortic arch obstruction. The incidence of potentially preventable significant physiologic compromise as a result of congenital heart disease in the general population is estimated to be 1 per 15,000 to 1 per 26,000 live births. CONCLUSIONS The incidence and timing of significant physiologic compromise as a result of critical congenital heart disease seems amenable to postnatal screening. Any viable screening strategy must be sensitive for lesions with aortic arch obstruction.

Abstract
BACKGROUND Infants with cardiovascular malformations are usually asymptomatic at birth. Earlier diagnosis is likely to improve outcome. OBJECTIVE To examine trends in the diagnosis of potentially life-threatening cardiovascular malformations. METHODS Ascertainment of all cardiovascular malformations diagnosed in infancy in the resident population of one English health region between 1985 and 2004. Infants with life-threatening cardiovascular malformations were all with hypoplastic left heart, pulmonary atresia with intact ventricular septum, transposition of the great arteries or interruption of the aortic arch; and those dying or undergoing operation within 28 days with coarctation of the aorta, aortic stenosis, pulmonary stenosis, tetralogy of Fallot, pulmonary atresia with ventricular septal defect or total anomalous pulmonary venous connection. RESULTS Cardiovascular malformations were diagnosed in infancy in 4444 of 690,215 live births (6.4 per 1000) and were potentially life threatening in 669 (15%). Overall, 55 (8%) were recognised prenatally, 416 (62%) postnatally before discharge from hospital, 168 (25%) in living infants after discharge and 30 (5%) after death. Antenatal diagnoses increased from 0 to around 20% and no case was first diagnosed after death in the past 6 years. However, the proportion going home without a diagnosis remains around 25%. Malformations most likely to remain undiagnosed at discharge were coarctation of the aorta (54%), interruption of the aortic arch (44%), aortic valve stenosis (40%) and total anomalous pulmonary venous connection (37%). CONCLUSIONS One in three infants with a potentially life-threatening cardiovascular malformation left hospital undiagnosed. Better early diagnosis is likely to be achieved by further improvements in antenatal diagnosis and more widespread use of routine pulse oximetry.

Abstract
OBJECTIVE Congenital cardiovascular malformations (CCVMs) are relatively common with a prevalence of 5-10 per 1000 live births. Pulse oximetry screening is proposed to identify newborns with critical CCVMs which are missed by routine prenatal ultrasound and by pre-discharge physical examinations. The purpose of this study was to identify the number of infants with a delayed diagnosis of critical CCVMs potentially detectable by pre-discharge pulse oximetry screening. PATIENTS AND METHODS Hospital Discharge records in New Jersey from 199-2004 for infants with critical CCVMs were identified using ICD-9 codes. These records were matched to the Electronic Birth Certificate records to identify newborns who were discharged as normal newborns and were later admitted with a diagnosis of critical CCVMs. Chart review was completed on these cases to confirm a delay in diagnosis. RESULTS Chart reviews confirmed delayed diagnosis of critical CCVM in 47 infants out of 670,245 births. Coarctation of the Aorta was the most common delayed diagnosis. The age at final diagnosis varied from 3 days to 6.5 months. CONCLUSIONS Further examination of pulse oximetry as a routine newborn screening service is warranted. Implementation of pre-discharge pulse oximetry screening for newborns may improve the timely detection of asymptomatic critical CCVMs.
