Abstract

It is well known that false positive on newborn hearing screening increases cost and maternal anxiety and worry. We aimed to evaluate the influence of mode of delivery (cesarean, vaginal) and hospital type (private, public) on false positives first screening test based on screening age. Identification and control of these factors can reduce the rate of false positives. Overall, 2784 infants were evaluated by otoacoustic emissions test. Hearing screening test was performed before hospital discharge. Finally, rate of the false-positive between both delivery group and hospital types were compared on the basis of screening age. False-positive results are obtained when a condition is not present, but the test results indicate that it is present. False positive rate in the first screening test in vaginal delivery was significantly higher than cesarean delivery and rate of significantly decreased with screening age. This reduction was observed only in cesarean delivery. Also the rate of false positives in public hospital is 2.2 fold higher than private hospital (P = 0.000) and with increase in screening age, the rate of False positive is significantly reduced in private hospitals while this decrease is not observed in public hospital. Screening test be retarded as much as possible in cesarean group and private hospital and be conducted just prior to hospital discharge also in public hospital, screening test are done in a separate room. In this way, false positive can be reduced by about six times and the cost and concerns imposed by the rate of false positives minimized.
