The objective of this investigation was to estimate the prevalence of any permanent hearing impairment (PHI) in the right and or left ear based on children included into a surveillance program in the local pediatric hearing health services (PHHS). and to analyze the costs. generated by the children.
The study is a cross-sectional study.
Which is part of a major prospective study. directed towards delineation of all aspects of pediatric audiology.
The present sample comprises 228 children. 115 males and 113 females. at a median age of 13 years. range 0-24. and involves all children living in the health district of the City of Copenhagen. who are or have been included in a local surveillance program with one (school children) or two (pre-school children) annual visits for children with PHI>20 dB HL at any frequency in either the left or the right ear.
The prevalence of PHI increases with increasing age. reaching its peak in the age band 10-14 years exhibiting a rate of 5.32 1000 (95% confidence intervals : 4.27 to 6.64 per 1000).
The estimated incidence of PHI in a ten year cohort born 1977-1986 is 325 100 000 children born (95% confidence intervals : 277 to 382 per 100 000).
The most frequent factor causing PHI is inheritance. showing an increase from 20% in 1977-1981 cohorts. to 37%, in 1982-1986 cohorts.
The costs involved in the PHHS concerning PHI varies considerably from approximately 345 000 to 990 000 DKr., depending on the model used for the economi...
