Creation and Implementation of the UCSF Laryngeal Symptom Diary for Trial Vocal Fold Injection.

Objectives: Patient recollection of their trial vocal fold injection outcomes is crucial in determining future treatment. This study aims to assess a new clinical tool, the UCSF Laryngeal Symptom Diary, for its ease of use, clinical value in patient symptom tracking, and utility for long-term decision-making following trial vocal fold injection.

Materials And Methods: In this prospective cohort study, consecutive patients undergoing trial vocal fold injection between June 2019 and January 2020 completed the UCSF Laryngeal Symptom Diary. Patients rated standardized and customized laryngeal symptoms weekly. Upon follow-up, a survey pertaining to the diary was completed by both the patient and treating laryngologist.

Results: A total of 29 patients opted to participate and were provided with the UCSF Laryngeal Symptom Diary. The diary was returned by 82.3% (n = 24/29) of patients. Mean time to follow up was 5.98 weeks. Survey participation rate was 93.1% (n = 27/29). From the patients' perspective, 66.7% (n = 18/27) found the diary useful in following their symptom evolution. Treating laryngeal surgeon noted excellent concordance between diary entries and patient's overall injection benefit (91.7%, n = 22/24). The diary was useful in clinician-recommendation of subsequent treatment options in 70.8% (n = 17/24) of patients.

Conclusion: The UCSF Laryngeal Symptom Diary is a patient friendly clinical tool for trial vocal fold injection that facilitates patient tracking of symptom evolution and helps guide treating clinicians in subsequent treatment planning.
