Intended patient population:

• The software is intended for patients with unilateral and bilateral, mild to profound hearing loss or in combination with chronic tinnitus, who require the fitting of a hearing instrument.
• Tinnitus masker is intended for patients from 18 years of age and above.

Indications:

• Please note, that indications are not derived from the fitting software but from compatible hearing aids.
• General clinical indications for the use of hearing aids and tinnitus masker are:
• Presence of hearing loss
  • Unilateral or bilateral
  • Conductive, sensorineural, or mixed
  • Mild to profound
• Presence of chronic tinnitus (only for hearing aids that offer tinnitus masker)

Contraindications:

• Please note, that contraindications are not derived from the fitting software but from compatible hearing aids.

General clinical contraindications for the use of hearing aids and tinnitus masker are:

• Hearing loss is not in the fitting range of the hearing aid (i.e., gain, frequency response)
• Acute tinnitus
• Deformity of the ear (i.e., closed ear canal, absence of the auricle)
• Neural hearing loss (retro-cochlear pathologies such as absent/non-viable auditory nerve)

The primary criteria for the referral of a patient for a medical or other specialist opinion and/or treatment are as follows:

• Visible congenital or traumatic deformity of the ear
• History of active drainage from the ear in the previous 90 days
• History of sudden or rapidly progressive hearing loss in one or both ears within the previous 90 days
• Acute or chronic dizziness
• Audiometric air-bone gap equal to or greater than 15 dB at 500 Hz, 1000 Hz, and 2000 Hz
• Visible evidence of significant cerumen accumulation or a foreign body in the ear canal
• Pain or discomfort in the ear
• Abnormal appearance of the eardrum and ear canal such as.
• • Inflammation of the external auditory canal
    • Perforated eardrum
    • Other abnormalities which the HCP believes are of medical concern

The HCP may decide that referral is not appropriate or in the best interests of the patient when the following applies:

• When there is sufficient evidence that the condition has been fully investigated by a medical specialist and any possible treatment has been provided.
• The condition has not worsened or changed significantly since the previous investigation and/or treatment
• If the patient has given their informed and competent decision not to accept advice to seek a medical opinion, it is permissible to proceed to recommend appropriate hearing aid systems subject to the following considerations:
  • The recommendation will not have any adverse effects on the patient’s health or general wellbeing
