Accuracy of Pulse Oximetry Screening for Critical Congenital Heart Defects after Home Birth and Early Postnatal Discharge.

OBJECTIVE: To assess the accuracy of pulse oximetry screening for critical congenital heart defects (CCHDs) in a setting with home births and early discharge after hospital deliveries, by using an adapted protocol fitting the work patterns of community midwives. STUDY DESIGN: Pre- and postductal oxygen saturations (SpO2) were measured ≥1 hour after birth and on day 2 or 3. Screenings were positive if the SpO2 measurement was <90% or if 2 independent measures of pre- and postductal SpO2 were <95% and/or the pre-/postductal difference was >3%. Positive screenings were referred for pediatric assessment. Primary outcomes were sensitivity, specificity, and false-positive rate of pulse oximetry screening for CCHD. Secondary outcome was detection of noncardiac illnesses. RESULTS: The prenatal detection rate of CCHDs was 73%. After we excluded these cases and symptomatic CCHDs presenting immediately after birth, 23 959 newborns were screened. Pulse oximetry screening sensitivity in the remaining cohort was 50.0% (95% CI 23.7-76.3) and specificity was 99.1% (95% CI 99.0-99.2). Pulse oximetry screening was false positive for CCHDs in 221 infants, of whom 61% (134) had noncardiac illnesses, including infections (31) and respiratory pathology (88). Pulse oximetry screening did not detect left-heart obstructive CCHDs. Including cases with prenatally detected CCHDs increased the sensitivity to 70.2% (95% CI 56.0-81.4). CONCLUSION: Pulse oximetry screening adapted for perinatal care in home births and early postdelivery hospital discharge assisted the diagnosis of CCHDs before signs of cardiovascular collapse. High prenatal detection led to a moderate sensitivity of pulse oximetry screening. The screening also detected noncardiac illnesses in 0.6% of all infants, including infections and respiratory morbidity, which led to early recognition and referral for treatment.

Pulse Oximetry Screening for Critical Congenital Heart Disease after Home Birth and Early Discharge.

OBJECTIVES: To assess the feasibility of pulse oximetry (PO) screening in settings with home births and very early discharge. We assessed this with an adapted protocol in The Netherlands. STUDY DESIGN: PO screening was performed in the Leiden region in hospitals and by community midwives. Measurements were taken ≥ 1 hour after birth and on day 2 or 3 during the midwife visit. Primary outcome was the percentage of screened infants with parental consent. The time point of screening, oxygen saturation, false positive (FP) screenings, critical congenital heart defects (CCHDs), and other detected pathology were registered. RESULTS: In a 1-year period, 3625 eligible infants were born. Parents of 491 infants were not approached for consent, and 44 refused the screening. PO screening was performed in 3059/3090 (99%) infants with obtained consent. Median (IQR) time points of the first and second screening were 1.8 (1.3-2.8) and 37 (27-47) hours after birth. In 394 infants with screening within 1 hour after birth, the median pre- and postductal oxygen saturations were 99% (98%-100%) and 99% (97%-100%). No CCHD was detected. The FP prevalence was 1.0% overall (0.6% in the first hours after birth). After referral, important noncritical cardiac and other noncardiac pathology was found in 62% of the FP screenings. CONCLUSIONS: PO screening for CCHD is feasible after home births and very early discharge from hospital. Important neonatal pathology was detected at an early stage, potentially increasing the safety of home births and early discharge policy.

Adapted protocol for pulse oximetry screening for congenital heart defects in a country with homebirths.

UNLABELLED: Pulse oximetry has been recommended for neonatal screening for critical congenital heart defects (CCHD) and is now performed in several countries where most births take place in hospital. However, there is a wide variation in perinatal care in European countries, and studies are now recommended to determine the accuracy and cost-effectiveness of CCHD screening in individual countries. In the Netherlands, a large part of births are supervised by a community-based midwife, at home or at policlinics. A screening protocol has been developed to fit into the Dutch perinatal setting, and also has the potential to increase safety in homebirths. CONCLUSION: the provided protocol might be useful for other countries that are planning to implement CCHD screening after homebirths or early discharge from hospital.

[A neonate with pustules]. / Een neonaat met pustels.

We describe a female neonate with non-grouped pustules directly postpartum without clinical signs of illness. There were no red maculae. At follow-up some pustules had turned to pigmented maculae, which confirmed the diagnosis of neonatal pustular melanosis. This benign transient condition occurs in 4-8% of dark-coloured neonates and in <1% of white neonates.
