The implementation of an aminoglycoside induced ototoxicity algorithm for people with cystic fibrosis.
Aminoglycoside antibiotics treat respiratory infections in cystic fibrosis (CF). An aminoglycoside induced ototoxicity algorithm (AIOA) was implemented to assess ototoxicity among people with CF treated with intravenous and/or inhaled aminoglycosides. Prior to AIOA implementation, 14 of 52 patients (27%) treated with intravenous aminoglycosides had an audiogram. In the 24 months post AIOA implementation, 43 of 44 patients (98%) treated with intravenous aminoglycosides had an audiogram, with 27 (63%) demonstrating abnormalities. Prior to AIOA development, 18 of 70 patients (26%) who received at least two courses of inhaled aminoglycosides had an audiogram. Post AIOA implementation, 33 patients qualified for an audiogram after receiving inhaled aminoglycosides. Of these, 19 (58%) had an audiogram and 10 (53%) had abnormalities. Overall, we identified 46 (61%) people with CF with hearing abnormalities compared to 2.4% in the CF Foundation Patient Registry. This suggests an urgent need for CF programs to implement AIOAs.
