Objective: Patients with recurrent respiratory papillomatosis (RRP) have significant vocal dysfunction which affects their performance at work. This study aimed to evaluate voice-related work productivity before and after ablative treatment for RRP. Methods: This is a prospective case series conducted at 2 academic laryngology outpatient clinics. Adult employed patients with RRP completed the Work Productivity & Activity Impairment instrument (WPAI), Voice Handicap Index (VHI-10), WorkHoarse, Hospital Anxiety and Depression Scale (HADS), and a demographics questionnaire immediately before and 1 month after ablative treatment of papilloma. The primary outcome measure was the change in work productivity impairment domain of the WPAI, and changes in ratings before and after ablation were compared using a Wilcoxon Signed-Rank test. Results: The 32 participants (mean age 45, 84% male) had a median (interquartile range) voice-related work productivity impairment score of 48.8% (30.0) at baseline which was improved to 5.0% (10.0) at 1 month after surgical ablation of papillomata (difference 30.0% (30.0) improvement). For the secondary outcome measures, there were significant improvements in VHI-10 (P <.001), self-reported voice quality (P =.002), and Workhoarse (P =.001), but no significant change in HADS. Conclusion: Patients with RRP experience significant voice-related work productivity impairment, and ablation of papillomata significantly improves work productivity.
