Objective: The aim of this study was to investígate the characteristics and performance of transient evoked oto-acoustic emission (TEOAE) hearing screening in newborns in Colombia, and analyze all possiblc variables and factors affccting thc rcsults.
Materials and methods: An obscrvational, dcscriptivc and rctrospcctivc study with bivariatc analysis was pcrformcd. The study population consistcd of 56,822 newborns evaluated at thc prívate institution, PREGEN. TEOAE testing was carried out as a pedialric hearing screening test from December 2003 to March 2012. The database from PREGEN was revised, and the protocol for evalualion included the same screening test performed twice. Demographic characteristics were recorded and the newborn’s background was evaluated. Basic statistics of the qualitative and quantitative variables, and statistical analysis were obtained using the chi-square test.
Residís: Of the 56,822 records examined, 0.28% were classed as abnormal, which corresponded to a prevalence of 1 in 350. In the screened newborns, 0.08% had a major abnormality or other clinical condition diagnosed, and 0.29% reported a family history of hearing loss. A prevalence of 6.7 in 10,000 was obtained for microtia, which is similar to the 6.4 in 10,000 previously reported in Colombia (database of the Latin-American Collaborative Study of Congenital Malformations - ECLAMC). Statistical analysis demonstrated an association bctwccn presenting with a major anomaly and a higher frequeney of abnormal rcsults on both TEOAE tests.
Conclusions: Newborns in Colombia do not currcntly undergo screening for thc carly detection of hearing impairment. The results from this study suggest TEOAE screening tests, when performed twice, are able to detect hearing abnormalities in newborns. This highlights the need to improve the long-term evaluation and moniloring of patients in Colombia through diagnostic tests, and lo provide tests that are both sensitive and specific. Furthermore, the use of TEOAE screening is justified by the favorable cost: benefit ratio demonstrated in many countries worldwide.
