Objective. The study aimed to determine the prevalence of birth defects among neonates born at the Philippine General Hospital (PGH) from January 2011 to December 2014.

Methods. Monthly censuses of all deliveries from January 2011 to December 2014 were obtained from the Section of Newborn Medicine. All deliveries with birth defects were coded using International Classification of Diseases-10 (ICD -10). The codes were tallied and classified as either an isolated, part of a recognizable syndrome, chromosomal syndrome or multi-malformed case (MMC). Period prevalence was then calculated.

Results. There was a total of 20,939 deliveries from 2011 to 2014 in PGH, of which 574 babies (2.74%) had a diagnosis of at least one birth defect. Two-hundred seventy-three babies (47.56%) had isolated defects; 130 (22.65%) with defects in MMC; 106 (18.47%) with defects as part of recognizable syndromes; and 65 (11.32%) with defects as part of chromosomal syndromes. One in 36 births has at least one birth defect, which is higher than that reported in other Asian countries.

Conclusion. Birth defects are significant causes of morbidity and mortality. Results of this study provide baseline data that can be used for future studies on the causation of such birth defects, and can be used to formulate policies on primary and secondary prevention. For a tertiary hospital like PGH, these data can serve as a guide towards allocation of resources and manpower towards the more common birth defects.
