Practice Patterns and Barriers in Botulinum Toxin Injection for the Treatment of Voice Disorders

Academic Article

Abstract

  • Laryngeal botulinum toxin injection is an important treatment modality for spasmodic dysphonia and other laryngeal disorders. We sought to compare usage patterns of laryngeal botulinum toxin injections for voice disorders and to identify and quantify inefficiencies and barriers in providing this treatment. A 26 item survey was written and approved for distribution by the American Academy of Otolaryngology-Head and Neck Surgery and the National Spasmodic Dysphonia Association. It was distributed to Otolaryngologists who perform laryngeal botulinum toxin injections via the e-mail lists of the National Spasmodic Dysphonia Association provider database, American Academy of Otolaryngology-Head and Neck Surgery Voice Committee and the American Laryngological Association Neurolaryngology Study Group. There were 81 survey participants who collectively reported performing >1700 laryngeal botulinum toxin injections for voice disorders monthly (Mean = 21.5 pts/month). Regarding botulinum toxin A (BtxA) vial use, 54% of participants reported using multiple doses per vial for different patients during a single clinic day, while 14% reported using pharmacy predrawn single use aliquots. A combination of usage practices was reported by 7% of participants. Using an individual vial per patient and discarding the unused remainder was reported by 26% of participants with an associated annual cost in wasted BtxA of $84,300 per physician. There is wide variation in injection practices regarding management of BtxA vials and adherence to an individual vial per patient policy is associated with significant waste of health care resources. Alternative approaches to BtxA vial use could positively impact health care resource utilization.
