[Development and use of an APHAB database].

A specific quality assurance questionnaire concerned with the provision of hearing aids was introduced that assesses elements of patient satisfaction within Germany's statutory healthcare system. A questionnaire-based assessment is now relevant for all physicians involved in the care of statutorily insured patients in Germany. The APHAB (Abbreviated Profile of Hearing Aid Benefit) questionnaire is the most widely used. The APHAB assesses several different situations: the normal hearing situation, hearing in noise, comprehension of speech in situations of echo or reverberation and hearing in loud situations. The APHAB questionnaire-based patient evaluation of the benefit of hearing aids represents the third pillar of audiological diagnostics, alongside classical pure-tone and speech audiometry. The objective of the APHAB database is to allow evaluation of individual patient data on the basis of a larger volume of data.
