Objectives: To compare the difference in ENT and Audiology visits, treatments dispensed and potential savings pre- and post-bone anchored hearing aid (BAHA) insertion in patients with chronic suppurative otitis media exacerbated by behind the ear hearing aids.
Design: A retrospective pilot study.
Setting: District General Hospital.
Participants: All patients who had BAHA inserted from January 2001 to January 2006.
Parameters: Age, gender, number of visits per month, treatments per month dispensed from the ENT and Audiology Departments and direct and limited indirect medical costs pre- and post-BAHA insertion.
Results: Twelve of 26 (46%) adult patients had BAHA inserted over the 5-year period for CSOM. The male to female ratio was 1 : 3 with a median age of 61 (range 29-81). The number of visits and treatments dispensed per month in the ENT Department fell from a mean of 0.42-0.33 (P < 0.08) and 0.22-0.14 (P < 0.02) respectfully. When the difference in medical cost was taken into account BAHA offered a potential saving of pound 627.80 per patient.
Conclusion: Although the initial acquisition of surgical equipment and BAHA sound processors is expensive, there is a reduction in the number of treatments and visits required for patients with chronic suppurative otitis media after BAHA is inserted leading to a reduction in average costs.
