Dysphonia Severity Index and Consensus Auditory-Perceptual Evaluation of Voice Outcomes, and Their Relation in Hospitalized Patients with COVID-19

Abstract

ObjectivesThis study aimed to compare the results of the Dysphonia Severity Index (DSI) and Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) between patients hospitalized with COVID-19 and healthy subjects, as well as to investigate the correlation between DSI and CAPE-V. Study designCross-sectional survey. Material and MethodsEighty subjects, 40 COVID-19 patients (with a mean age of 41.2± 5.41) and 40 healthy subjects (with a mean age of 44.50± 3.50) participated in this study. Assessments included the DSI for aerodynamic-acoustic measurement and the Persian version of Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) for evaluating auditory-perceptual voice quality. Data were analyzed by means of the independent t-test and Pearson correlation at the 5% significance level. ResultsThe results showed COVID-19 patients got significantly lower score in DSI compared to healthy subjects (P < 0.05). Moreover, the patients with COVID-19 had higher scores in all categories of voice production (severity, roughness, loudness, pitch, strain and breathiness) than the healthy group (P < 0.05). Comparing the result of the two voice assessments in each group revealed that there was a greater negative significant correlation in the diseased group (r p: -0.68, P: 0.001) than in the healthy group (r p: -0.37,P: 0.049). ConclusionsHospitalized COVID-19 patients experience deviations in the voice quality and acoustic-aerodynamic features of their voice. Also, the results of this study showed the patient group had higher perceptual dysphonia and lower voice quality compared to the healthy group. Further studies are recommended to determine the relationship between objective and subjective voice evaluation in patients with COVID-19 after recovery.
