Awareness and Attitude About Ototoxic Drugs Among Medical Doctors in Arar City, Saudi Arabia.

OBJECTIVES

The purpose of this study was to assess the awareness of ototoxicity among medical doctors in Arar City, Saudi Arabia.

METHODS

This is a cross-sectional study based on a pre-formed validated questionnaire (Appendix) that included three sections covering participants' demographic data (three questions), their attitudes (five questions), and knowledge (13 questions) regarding drug-induced ototoxicity.

RESULTS

After obtaining their informed consent, 213 physicians from government and private sector health facilities in Arar were enrolled in the study. Interns and general practitioners represented 57.8% of the participants; consultants represented 17.8%. Only 71.8% of participants were interested in drug-induced ototoxicity, while 26.3% considered ototoxicity a rare complication. Approximately 90% of the participants were knowledgeable about the adverse effects of drugs on the vestibulocochlear system, and 26.7% reported having experienced cases of drug-induced ototoxicity in their practice. Participants showed an overall knowledge score about ototoxicity of 9.3±3.27 (out of 14). The knowledge score was significantly higher (p-value=0.0007) for participants with more years of clinical experience. The most widely known ototoxic drug for participants was frusemide (72.3%), followed by aminoglycoside (68.5%), while acetaminophen (44.1%) ototoxicity was the least known among participants.

CONCLUSION

Awareness of drug-induced ototoxicity is satisfactory among physicians in the Northern Borders region. However, workshops about all types of drugs with ototoxic effects and the main lines for the management of drug-induced ototoxicity are recommended to increase awareness.
