Screening for latent malformations: cost effectiveness in neonates with correctable anomalies

Area of Science:

• Pediatric Surgery
• Neonatal Screening
• Medical Economics

Background:

• Infants with surgically correctable anomalies may have undetected latent congenital malformations.
• Early detection of these anomalies is crucial for effective management and improved patient outcomes.
• The cost-effectiveness of screening programs for these conditions requires careful evaluation.

Purpose of the Study:

• To assess the cost-effectiveness of a screening program for latent malformations in infants with surgically correctable anomalies.
• To identify specific conditions and patient subgroups that would benefit from targeted screening.
• To determine the utility of intravenous pyelography (IVP) in screening for these latent defects.

Main Methods:

• Review of a screening program involving 276 infants with conditions such as esophageal atresia, imperforate anus, omphalocele, gastroschisis, or diaphragmatic hernia.
• Screening for latent congenital anomalies beyond routine history, physical examination, and roentgenograms.
• Analysis of the detection rates and clinical significance of identified latent malformations.

Main Results:

• While the screening program detected additional malformations, many congenital defects were missed and became evident later.
• Routine screening for all infants with surgically correctable anomalies was found not to be cost-effective.
• Screening IVPs were indicated for infants with esophageal atresia, high pouch imperforate anus, and possibly diaphragmatic hernia.

Conclusions:

• Routine screening for latent malformations is not universally cost-effective in neonates with surgically correctable anomalies.
• Directed screening is indicated for selected neonates, optimizing resource allocation.
• Specific conditions like esophageal atresia and high imperforate anus warrant screening IVPs, while others like gastroschisis do not.
