Insights

Early detection of childhood hearing loss has improved in Turkey, with suspicion, identification, and intervention occurring at younger ages. However, current ages still lag behind recommended guidelines for infant hearing.

Area of Science:

  • Pediatrics
  • Audiology
  • Public Health

Background:

  • Early identification and intervention are crucial for managing childhood hearing loss.
  • Timeliness of diagnosis and treatment significantly impacts developmental outcomes.
  • Established guidelines exist for optimal age benchmarks for infant hearing care.

Purpose of the Study:

  • To determine the mean ages of suspicion, identification, amplification, and intervention for children with hearing loss in Turkey.
  • To compare these age benchmarks between two distinct time periods (1991-1994 and 1999-2004).
  • To assess progress towards recommended early intervention timelines.

Main Methods:

  • Retrospective analysis of data from 199 children with severe to profound hearing loss (1999-2004).
  • Calculation of intervals between suspicion, identification, amplification, and intervention.
  • Comparison with data from 156 children with hearing loss (1991-1994).
  • Data collection via family interviews and hospital records.

Main Results:

  • Mean age of suspicion was 12.5 months; identification at 19.4 months; amplification at 26.5 months; and intervention at 33.0 months (1999-2004 cohort).
  • A significant decrease in ages of suspicion, identification, and intervention was observed in the later period (1999-2004) compared to the earlier period (1991-1994).

Conclusions:

  • Significant improvements in the timeliness of hearing loss suspicion, identification, and intervention have been achieved in Turkey.
  • Despite progress, the ages for suspicion, identification, amplification, and intervention remain considerably later than recommended by the Joint Committee on Infant Hearing.
  • Further efforts are needed to align current practices with international best practice guidelines for early childhood hearing loss management.
