Current Status of Newborn Bloodspot Screening Worldwide 2024: A Comprehensive Review of Recent Activities (2020-2023). Int J Neonatal Screen 2024; 10:38. [PMID: 38920845 PMCID: PMC11203842 DOI: 10.3390/ijns10020038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 03/28/2024] [Accepted: 03/28/2024] [Indexed: 06/27/2024] Open
Abstract
Newborn bloodspot screening (NBS) began in the early 1960s based on the work of Dr. Robert "Bob" Guthrie in Buffalo, NY, USA. His development of a screening test for phenylketonuria on blood absorbed onto a special filter paper and transported to a remote testing laboratory began it all. Expansion of NBS to large numbers of asymptomatic congenital conditions flourishes in many settings while it has not yet been realized in others. The need for NBS as an efficient and effective public health prevention strategy that contributes to lowered morbidity and mortality wherever it is sustained is well known in the medical field but not necessarily by political policy makers. Acknowledging the value of national NBS reports published in 2007, the authors collaborated to create a worldwide NBS update in 2015. In a continuing attempt to review the progress of NBS globally, and to move towards a more harmonized and equitable screening system, we have updated our 2015 report with information available at the beginning of 2024. Reports on sub-Saharan Africa and the Caribbean, missing in 2015, have been included. Tables popular in the previous report have been updated with an eye towards harmonized comparisons. To emphasize areas needing attention globally, we have used regional tables containing similar listings of conditions screened, numbers of screening laboratories, and time at which specimen collection is recommended. Discussions are limited to bloodspot screening.

Abstract
Pulse oximetry screening (POS) was first described over 20 years ago. However, in recent years, major clinical trials have demonstrated consistent test accuracy for the detection of critical congenital heart defects (CCHD). International uptake of POS has progressed well over the last 10 years with most major high-income countries now recommending screening. This review describes the evidence base which has led to this, the current debate regarding choice of screening algorithm, and the future areas for further research.

Changing epidemiology of congenital heart disease: effect on outcomes and quality of care in adults. Nat Rev Cardiol 2023; 20:126-137.

Abstract
The epidemiology of congenital heart disease (CHD) has changed in the past 50 years as a result of an increase in the prevalence and survival rate of CHD. In particular, mortality in patients with CHD has changed dramatically since the latter half of the twentieth century as a result of more timely diagnosis and the development of interventions for CHD that have prolonged life. As patients with CHD age, the disease burden shifts away from the heart and towards acquired cardiovascular and systemic complications. The societal costs of CHD are high, not just in terms of health-care utilization but also with regards to quality of life. Lifespan disease trajectories for populations with a high disease burden that is measured over prolonged time periods are becoming increasingly important to define long-term outcomes that can be improved. Quality improvement initiatives, including advanced physician training for adult CHD in the past 10 years, have begun to improve disease outcomes. As we seek to transform lifespan into healthspan, research efforts need to incorporate big data to allow high-value, patient-centred and artificial intelligence-enabled delivery of care. Such efforts will facilitate improved access to health care in remote areas and inform the horizontal integration of services needed to manage CHD for the prolonged duration of survival among adult patients.

Gupta SK. Cyanotic congenital heart disease - Not always blue to provide a clue: Time to replace cyanosis with arterial desaturation! Ann Pediatr Cardiol 2022; 15:511-514. [PMID: 37152515 PMCID: PMC10158465 DOI: 10.4103/apc.apc_226_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2021] [Revised: 02/11/2022] [Accepted: 04/07/2022] [Indexed: 03/03/2023] Open
Abstract
Despite right-to-left shunt, not all patients with so-called cyanotic congenital heart disease (CHD) are cyanosed at all times. Moreover, despite undisputed clinical utility, cyanosis is unreliable for the detection of arterial desaturation. Pulse oximetry, on the other hand, provides a much easier, reliable, and accurate method for detecting arterial desaturation. For optimal detection, therefore, it is perhaps sensible to replace cyanosis with pulse oximetry-based detection of arterial desaturation in all cases with suspected CHD.

Abstract
Background: Congenital heart disease (CHD) has emerged as a leading contributor to infant mortality in many low-and middle-income countries (LMICs). We report early results of a population health program for CHD, implemented in the state of Kerala, India. Objective: Report on early results of a population-based program implementation in a LMIC to reduce mortality from CHD. Methods: We retrospectively analyzed the results of an innovative population-based program to address CHD. We devised, implemented and evaluated measures in the care continuum to address deficiencies in CHD care in Kerala, India, through structured capacity building initiatives that enabled early detection, prompt stabilization and expedited referral to a tertiary center. A comprehensive web-based application enabled real-time case registration, prioritization of treatment referrals, and tracking every child registered with CHD. Advanced pediatric heart care was delivered through a public-private partnership. Results: Early identification, referral, and treatment of infants with CHD were improved. The web-based application, ‘Hridyam,’ registered 502 cases in 2017 (Aug–Dec), 2190 in 2018 and 3259 in 2019; infants < 1 year of age constituted 56, 62 and 63% in these years, respectively. The number of heart operations managed through Hridyam rose from 208 to 624 and 1227 in the same years, with overall 30-day mortality of 2.4%. Overall- and CHD-related infant mortality in Kerala fell by 21.1% and 41.0%, respectively, over the same interval. Unmet challenges include lack of universal catchment and a 5% preoperative mortality rate. Conclusion: We demonstrate successful implementation of a population-based and real-time approach to reduce CHD mortality. We speculate that Hridyam has contributed to the observed decline in Kerala’s IMR from 12 to 7 between 2016 and 2019. This model has potential applications for other conditions, and in other jurisdictions, especially LMICs considering building CHD capacity.

Abstract
The possibility of pulse oximetry screening (POS) for congenital heart defects was first described over 20 years ago. Since then, an accumulation of research evidence and clinical practice experience has established POS as an important test to detect critical congenital heart defects (CCHDs). POS meets the criteria for universal screening and professional bodies around the globe have recommended universal POS. Many countries have already adopted POS while several others are working towards its implementation. In low and low-middle-income countries (LLMIC), POS has the additional potential for reducing morbidity and mortality from neonatal sepsis. This review summarises the evidence for POS and looks at current global uptake and different approaches to the implementation of POS.

Abstract
OBJECTIVES to validate the content and appearance of the booklet "Going home after a child's cardiac surgery" and assess family members' cognitive learning regarding its use. METHODS a methodological and quasi-experimental study of before and after type, with semi-structured interview, pre-test and reading of the booklet in a hospital; post-test and validation occurred after hospital discharge. Wilcoxon non-parametric statistics were used. RESULTS nineteen family members of children with heart disease participated. The average of correct answers increased 14 percentage points from pre- to post-test; most were medication errors. There was a significant difference (p <0.0001) in the comparison between cognitive knowledge prior to using the booklet and learning acquired from its use. All items received a positive rating, except font size. CONCLUSIONS the booklet helps family members to understand a child's needs after cardiac surgery, and can be used to prevent unwanted occurrences and enable safe care at home.

Abstract
OBJECTIVE This study explored the feasibility of congenital heart disease (CHD) screening by combining a percutaneous oxygen saturation (POX) test with cardiac auscultation method in neonates. METHODS POX tests and cardiac auscultation were used concurrently to screen 8305 neonates born in Jinjiang City Hospital between January 2016 and December 2018 for CHD. The positive screening results (positive POX or positive cardiac auscultation) were confirmed with echocardiography, while any false negative results were identified through follow-up and parent feedback. Sensitivity, specificity, positive/negative predictive values, Youden's index, and the area under the receiver operator characteristic curve (AUC) of the single use and combined use of the two methods (a POX test and auscultation) were calculated, and the results were compared. RESULTS Among 8305 neonates, 22 cases were positive for POX alone, of which 6 cases were diagnosed by echocardiography; 83 cases were positive for cardiac auscultation alone, of which 47 cases were diagnosed by echocardiography; and 8 cases were positive for both methods, all of which were confirmed by echocardiography. Four more cases were confirmed during follow-up. Sensitivity, specificity, and the positive and negative predictive values of combined screening were 93.85%, 99.37%, 53.98% and 99.95%, respectively, while Youden's index was 0.93, and the AUC was 0.966. Sixty-five cases of CHD were diagnosed, the total incidence being 7.82%, and a ventricular septal defect was found to be the most common type. CONCLUSION The combination of POX test and cardiac auscultation as a screening method for neonatal CHD can reduce missed diagnoses and increase the detection rate of CHD in newborn infants.

BMC Public Health 2021; 21:1044. [PMID: 34078335 PMCID: PMC8173734 DOI: 10.1186/s12889-021-11034-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 05/11/2021] [Indexed: 11/12/2022] Open
Abstract
Background Many studies have been conducted to assess the incidence of congenital heart disease (CHD). However, results were greatly inconsistent among these studies with a broad range of findings. Methods A prospective census-based cohort study was conducted in Qingdao, China, from August 1, 2018 to April 30, 2019. All of the local registered pregnant women were continuously investigated and followed from 15 to 20 weeks of gestation to delivery, tracking the CHD cases in both the fetal and neonatal stages. A logistic regression model was applied to assess the association between CHD and possible risk factors. Results The positive rate of prenatal CHD screening was 14.36 per 1000 fetuses and the incidence of CHD was 9.38 per 1000 live births. Results from logistic regression indicated that, living in the countryside (odds ratio, (OR): 0.771; 95% confidence interval, (CI): 0.628–0.946) and having a childbearing history (OR: 0.802; 95%CI: 0.676–0.951) were negatively associated with CHD. However, twin pregnancy (OR: 1.957, 95% CI: 1.245–3.076), illness in the first trimester (OR: 1.306; 95% CI: 1.048–1.628), a family history of CHD (OR: 7.156; 95% CI: 3.293–15.552), and having a child with a birth defect (OR: 2.086; 95% CI: 1.167–3.731) were positively associated with CHD. Conclusion CHD is a serious health problem in Qingdao. The CHD incidence found in this study was similar to existing research. The positive rate of prenatal CHD screening was higher than the incidence of neonatal CHD. Moreover, CHD risk factors were identified in our study, and our findings may have great implications for formation CHD intervention strategies.

Abstract
Background The level of representation of women in cardiology remains low compared to that of men, particularly in leadership positions. We evaluated gender disparity in the authorship of Canadian Cardiovascular Society (CCS) guidelines. Methods All CCS guidelines from 2001-2020 were identified. Gender was assessed based on pronoun use in the biographies and social media of the authors. Only primary panel authors were included in our analysis. Stratified analyses were performed based on subspecialties. Results A total of 76 guidelines were identified, with 1172 authors (26% women, 74% men, P < 0.0001), with no significant change in percentage of women authors over 2 decades, (37.1% in 2001, 36.3% in 2020, P = 0.34). Inclusion of women as authors occurred less frequently than inclusion of men in general cardiology guidelines (20.1% vs 79.9%, P < 0.0001) and all subspecialties—heart failure (36.4% vs 63.6%, P < 0.0001), interventional cardiology (12.6% vs 87.4%, P < 0.0001), electrophysiology (20.2% vs 79.8%, P < 0.0001), and pediatric cardiology (41.7% vs 58.3%, P = 0.02). It was less likely for women to be a chair or cochair of a guideline writing committee, compared with men (20.1% vs 79.8%, P < 0.0001). There were 609 unique authors (25.6% women, 74.4% men, P < 0.0001), 542 unique medical doctorate (MD) authors (20.7% women, 79.3% men, P < 0.0001), and 67 unique non-MD authors (65.7% women, 34.3% men, P = 0.0003). Conclusions There is a persistent shortfall in the inclusion of women authors for CCS guidelines, which has not changed over time. Further efforts are required to promote women's inclusion in leadership roles, which may lead to authorship of the guidelines.

Abstract
Background Critical congenital heart diseases (CCHDs), 10% to 25% of all CHD, are duct-dependent defects that are life threatening without intervention in the neonatal period or infancy. One third of neonates with CCHDs are discharged home undetected and have a poorer outcome. Pulse oximetry screening before discharge is increasingly being used to diagnose CCHDs in developed countries. Methods This prospective observational study conducted at a tertiary care hospital from September 2016 to March 2019 screened all asymptomatic intramural neonates after 24 hours of life using a Masimo pulse oximeter with signal extraction technology using the standard American Academy of Pediatrics algorithm. A positive screen was followed by a confirmatory echocardiography (gold standard) and a negative screen by clinical examination at 6, 10 and 14 weeks and identification of readmissions during the study period. Results A total of 1855 neonates (82.99% of the eligible 2235 neonates) underwent screening at a mean (SD) age at screening of 32.4 (6.8) hours and took a mean (SD) time of 3.5 (1.2) minutes. The sensitivity, specificity, positive and negative predictive value of pulse oximetry screening for detection of CCHDs in asymptomatic neonates was 75% (95% CI: 28.91% to 96.59%), 99.29% (95% CI: 98.79% to 99.60%), 18.75% (95% CI: 5.80% to 43.80%) and 99.94% (95% CI: 99.66 to 99.99%), respectively. Conclusion Pulse oximetry screening of asymptomatic neonates between 24 and 48 hours of life improved the detection of CCHDs with high specificity and negative predictive value, moderate sensitivity and a reasonably low false positivity rate.

Abstract
OBJECTIVE Previously conducted cost-effectiveness analyses of pulse oximetry screening (POS) for critical congenital heart defects (CCHDs) have shown it to be a cost-effective endeavour, but the geographical setting of Ontario in relation to its vast yet sparsely populated regions presents unique challenges. The objective of this study was to estimate the cost-effectiveness of POS for CCHD in Ontario, Canada. METHODS A cost-effectiveness analysis, comparing POS to no POS, was conducted from the Ontario healthcare payer perspective using a Markov model. The base case was defined as a well-appearing newborn at 24 h of age. Outcome measures, including quality-adjusted life months (QALMs), lifetime costs, and incremental cost-effectiveness ratios (ICER) [ΔCost/ΔQALMs], were calculated over a lifetime horizon. All outcomes were discounted at 1.5% per year. Cost-effectiveness was assessed using an a priori ICER threshold of CAD$4166.67 per QALM (equivalent to CAD$50,000 per quality-adjusted life year). Deterministic and probabilistic sensitivity analyses were conducted to assess parameter uncertainty. RESULTS Implementation of POS is expected to lead to timely diagnosis of 51 CCHD cases annually. The incremental cost of performing POS was estimated to be $27.27 per screened individual, with a gain of 0.02455 QALMs. This yielded an ICER of CAD$1110.79 per QALM, well below the pre-determined threshold. The probabilistic sensitivity analysis estimated a 92.3% chance of routine implementation of POS being cost-effective. CONCLUSION Routine implementation of POS for CCHD in Ontario is expected to be cost-effective.

Abstract
Seven years after its addition to the US Recommended Uniform Screening Panel, newborn screening for critical congenital heart disease (CCHD) using pulse oximetry became mandatory in the United States. Although CCHD newborn screening reduces morbidity and mortality, there remain important opportunities to improve. An expert panel convened for a 1-day meeting in September 2018, including subject matter experts and representatives from stakeholder organizations. Presentations on CCHD outcomes, variations in approach to screening, and data and quality improvement helped identify improvement opportunities. The expert panel concluded that sufficient evidence exists to recommend modifying the current American Academy of Pediatrics algorithm by (1) requiring an oxygen saturation of at least 95% in both (formerly either) the upper and lower extremities to pass and (2) requiring only 1 repeat screen instead of 2 for cases that neither pass nor fail initially. The panel underscored the importance of improving public health reporting by further specifying the targets of screening and criteria for reporting outcomes (false-negative and false-positive cases). The panel also highlighted the need to ensure sufficient public health funding for CCHD newborn screening and opportunities for education and global implementation. Newborn screening for CCHD using pulse oximetry has led to significant improvements in child health outcomes. However, further important work is required to understand and improve the effectiveness and efficiency of screening.

Abstract
Introducción: Las cardiopatías congénitas son la principal causa de morbimortalidad cardiovascular en los neonatos, por ello, es necesario un diagnóstico temprano para iniciar un tratamiento adecuado. Objetivo: Evaluar la utilidad de la oximetría de pulso como método de tamizaje para su detección. Metodología: Se realizó un estudio analítico observacional de cohorte prospectivo en el que se usó la oximetría de pulso como método de tamizaje para enfermedad cardíaca a 376 recién nacidos. El algoritmo Americano de Tamizaje Cardíaco fue utilizado como fundamento para el estudio. Resultados: Se realizaron ecocardiogramas en los que se identificó un 90% de una cardiopatía congénita acianógena y el 10% fueron normales. Discusión: Se deseaba generar evidencia acerca de la detección temprana de cardiopatías congénitas con el uso de la oximetría de pulso en recién nacidos y se obtuvo resultados que favorecen su uso. Efectivamente en quienes obtuvieron un tamizaje positivo, el ecocardiograma evidenció una cardiopatía acianógena la mayoría de las veces.

Abstract
BACKGROUND It has been hypothesized that 4 doses of palivizumab, a neutralizing monoclonal antibody against respiratory syncytial virus (RSV), administered during a fixed-date RSV season may reduce hospital admissions comparably to the standard 5-dose schedule. We report outcomes in children with congenital heart disease approved to receive this 4-dose palivizumab schedule in British Columbia. METHODS We performed a population-based descriptive cohort analysis of all 406 approved palivizumab courses over 4 seasons (2012/13 to 2015/16) in 325 children with hemodynamically significant congenital heart disease enrolled in the British Columbia RSV Immunoprophylaxis Program. The primary outcome was in-season hospital admission for potential RSV-related lower respiratory tract infection (LRTI). Secondary outcomes include timing of admission in relation to dosing. Analysis was by intention-to-treat. RESULTS Of the 406 approved palivizumab courses, 391 were administered. In 33 cases (8.4%), an additional dose was given immediately after cardiac bypass surgery. There were 17 RSV-confirmed hospital admissions (median age of children 5.9 mo [interquartile range 4-10 mo]) and 8 admissions in which the child was not tested for RSV, for a maximum of 25 potential RSV-related admissions (6.2 per 100 approvals [95% confidence interval 4.0-9.0]). Twenty-four (96%) of the 25 admissions occurred within the 4-dose palivizumab dosing period, and the remaining admission occurred 52 days after the fourth dose. Sixty-four (72%) of 89 admissions were RSV-negative; the baseline clinical characteristics of these children were not different from those of children with RSV-confirmed admissions. INTERPRETATION In infants with hemodynamically significant congenital heart disease, a 4-dose fixed-date palivizumab schedule over a 6-month season provided seasonal protection comparable to that in a clinical trial involving a standard 5-dose schedule. Because RSV was responsible for only 19% of admissions for LRTI in our cohort, it is critical to continue to emphasize other preventive measures, including family education toward proper hand hygiene, breast-feeding and limiting infectious exposures in children at high risk.

Abstract
This statement provides guidance for health care providers to ensure the safe discharge of healthy term infants who are born in hospital and who are ≥37 weeks' gestational age. Hospital care for mothers and infants should be family-centred, with healthy mothers and infants remaining together and going home at the same time. The specific length of stay for newborn infants depends on the health of their mother, infant health and stability, the mother's ability to care for her infant, support at home, and access to follow-up care. Many mother-infant dyads are ready to go home 24 h after birth. Parent or guardian education and assessment of discharge readiness are important components of discharge planning. Each infant must have an appropriate discharge plan, including identification of the infant's primary health care provider and assessment by a health care provider 24 h to 72 h after discharge.

Abstract
A review is presented of data published in medical literature related to the screening used for the early detection of complex congenital heart disease in apparently healthy newborns in several cities of the world, including those reported in Mexico. The screening was performed due to the knowledge of the pathophysiology of indirect hypoxia data, observation of differential cyanosis and the consequent difference in the values of pre- and post-ductal pulse oximetry derived from the ductal and/or atrial septal defect dependence of several severe congenital heart diseases. Multicentre research studies have also been carried out on a massive scale, thus justifying the usefulness of the practice for its daily implementation and at international level. Additionally, legislative topics are cited in our country as part of the efforts to establish the mandatory nature of the screening throughout the Mexican Republic.

Abstract
Pulse oximetry screening is safe, noninvasive, easy to perform and proven to enhance detection of critical congenital heart disease in newborns. However, this test has yet to be adopted as routine practice in Canada. The present practice point highlights essential details and recommendations for screening, which research has shown to be highly specific, with low false-positive rates. Optimal screening for critical congenital heart disease should include prenatal ultrasound, physical examination and pulse oximetry screening. Screening should be performed between 24 hours and 36 hours postbirth, using the infant's right hand and either foot to minimize false-positive results. Newborns with abnormal results should undergo a thorough evaluation by the most responsible health care provider. When a cardiac diagnosis cannot be excluded, referral to a paediatric cardiologist for consultation and echocardiogram is advised.

Abstract
BACKGROUND Barriers to widespread implementation of pulse oximetry screening of critical congenital heart defects (CCHD) in newborns include increasing trends of out-of-hospital births and cost of equipment. In recent years, smartphone-compatible pulse oximeters have appeared on the market, but the validity of such devices in the setting of CCHD screening has not been evaluated. OBJECTIVES To compare the performance in CCHD screening of a smartphone-paired pulse oximeter (Masimo iSpO2-Rx™) and a hospital-grade pulse oximeter (Masimo Radical-7™). METHODS Preductal (right hand) and postductal (either foot) saturations were determined in a population of 201 term newborns by 2 independent teams, one using the Radical-7 and the other using the iSpO2-Rx. Bland-Altman analysis was applied to calculate mean bias and 95% limits of agreement between the 2 pulse oximeters. RESULTS For the preductal oxygen saturation, the mean bias (Radical-7 minus iSpO2-Rx) was -0.08 (SD 1.76) and the lower and upper limits of agreement were -3.52 and 3.36, respectively. For the postductal oxygen saturation, the mean bias was -0.11 (SD 1.68) and the lower and upper limits of agreement were -3.49 and 3.18, respectively. In addition, the iSpO2-Rx provided reliable measurements of saturations below 95% in a group of 12 infants admitted to the neonatal intensive care unit. CONCLUSIONS Our data suggest that CCHD screening with the Masimo iSpO2-Rx is feasible and accurate. The use of reliable smartphone-paired pulse oximeters may contribute to the extension of CCHD screening to home births and low resource settings.
