A Retrospective Chart Abstraction to Investigate the Prevalence of Chronic Sialorrhea, and the Real-world Use of incobotulinumtoxinA Injections in Male and Female Participants Aged 18 Years and Older With Chronic Sialorrhea

A retrospective, multicenter chart abstraction to investigate the prevalence of chronic sialorrhea, and the real-world use of incobotulinumtoxinA injections in male and female participants aged 18 years and older with chronic sialorrhea. Patients who come to a neurologic clinic in the past 6 months from the start date will be screened by searching for the ICD-10 code and diagnosis of sialorrhea and cross-referencing with those patients also being prescribed incobotulinumtoxinA. Data will be retrieved from the electronic medical record.
