What is the purpose of using pre- and post-fitting data from tools like APHAB or COSI?

Using pre- and post-fitting data from tools like the Abbreviated Profile of Hearing Aid Benefit (APHAB) or the Client Oriented Scale of Improvement (COSI) is primarily focused on validating and verifying patient outcomes after they have received hearing aids. These assessments provide a structured way to evaluate how effectively the hearing aids are meeting the patient's needs.

By comparing the pre-fitting data, which reflects the patient's experience and challenges prior to receiving hearing aids, with the post-fitting data that captures the patient’s current experiences, practitioners can identify specific benefits or improvements in hearing function, communication abilities, and overall quality of life. This validation is essential for both the hearing care provider and the patient, as it demonstrates whether the fitting has been successful and if any further adjustments or interventions are necessary.

In terms of patient-centered care, this data can guide ongoing therapeutic decisions and help in counseling, ensuring that patients feel heard and that their feedback is instrumental in their care journey. Additionally, validating outcomes may also be important for insurance claims or further clinical studies into hearing aid effectiveness.
