  • Audiology
  • Diagnostic Accuracy

Context:

  • Outpatient university ear, nose, and throat (ENT) clinic in Southern Brazil.
  • Cross-sectional study conducted from 1999 to 2002.
  • Involved 795 patients undergoing audiometric testing.

Purpose:

  • To evaluate the diagnostic value of patient-reported hearing complaints.
  • Assessed sensitivity, specificity, and predictive values of hearing loss complaints.
  • Compared subjective complaints with objective audiometric results.

Summary:

  • Hearing loss complaints demonstrated 80.9% sensitivity and 86.5% positive predictive value.
  • Specificity was 69.6%, with a negative predictive value of 60.4%.
  • Audiometric testing confirmed its reliability despite the subjective nature of complaints.
