Abstract
OBJECTIVE: To determine the risk factors for aminoglycoside toxicity in the elderly.
DESIGN: Prospective observational study.
SETTING: Acute care teaching hospital serving predominantly veterans.
PARTICIPANTS: Consecutive patients aged 70 years and over receiving aminoglycosides.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: Thirteen (15%) of 88 patients developed aminoglycoside-related nephrotoxicity and 3 (3.4%) developed otovestibular toxicity. Multivariate analysis showed that increasing duration of aminoglycoside therapy was the only factor significantly associated with development of toxicity. Elevated baseline serum creatinine level (p=.02) and use of allopurinol (p=.03) were risk factors specifically for nephrotoxicity. Only 2 (3.9%) of 51 patients receiving aminoglycosides 7 or fewer days developed nephrotoxicity, as compared with 11 (30%) of 37 receiving the drugs for 8 to 14 days and 4 (50%) of 8 treated for more than 14 days.
CONCLUSIONS: Although toxicity is common in elderly patients treated with aminoglycosides, limiting the duration of aminoglycoside therapy to less than a week can substantially reduce risk of toxicity.
