Abstract: Assessment of a) the efficacy of hearing loss screening in baby check-ups at the age of 6 to 8 months b) the efficiency and efficacy using parent questionnaires about hearing loss risk factors and parents' concern about the child's hearing as part of baby check-up. Methods: The analyses are based on 7282 baby check-ups carried out in 47 pediatricians' offices in the Dusseldorf area from July 1991 to March 1993: 3385 of these check-ups were performed in the traditional manner (period A; July 1, 1991, to January 1, 1992; 3897 check-ups involved parent questionnaires (period B June 1, 1992, to March 31, 1993). All children who failed the tests and a random sample of those who had passed the test when tested in the traditional manner, were offered extensive hearing assessment. Results: In period A, 4.3% of the children failed the test as compared to 21.7% with the first version of the questionnaire and 14.3% with a revised questionnaire in period B. Compliance to the offer of extensive hearing assessment was unsatisfactory (53% in period A and 63% in period B). The first extensive hearing examination failed to distinguish healthy children from children with probable sensorineural hearing loss in about 30% of the patients, mainly because of glue ear. One child with sensorineural hearing loss was identified by the screening in period A as compared to six children in period B. Conclusions: 1) The sytematic use of parent questionnaires in baby check-ups at ages 6 to 8 months is likely to increase the efficacy of the screening. 2) The efficiency of the questionnaires currently in use, however, needs to be improved and can be improved with the data from the study. 3) The compliance with extensive hearing testing in children who have failed the screening test must be improved. 4) Due to the high prevalence of conductive hearing loss in this age group, treatment of potential glue ear problems is mandatory before referral for extensive testing for sensorineural hearing loss.
