Abstract
BACKGROUND: Voice production or phonation has a crucial role in human communication and function. It is done by specialized coordination of laryngeal and respiratory neuromuscular control. The prolonged use or abuse of voice may lead to vocal fatigue and vocal fold tissue damage. In professions with heavy vocal loading (e.g. school and kindergarten teachers), occupational voice disorders threatening working ability are common. In this study we aim to assess the prevalence of voice disorders and its risk factors among hospital support staff. AIM & OBJECTIVES AIM OF THE STUDY: To study the prevalence of voice disorders in Medical Record officers and Multifunctional Computer Terminal Technicians working at counters in CMC, Vellore. OBJECTIVES: 1. The prevalence of voice disorders in Medical Record officers and Multifunctional Computer Terminal Technicians working at counters by voice analysis and stroboscopy. 2. To assess the risk factors associated with developing voice disorders in Medical Record officers and Multifunctional Computer Terminal Technicians working at counters. MATERIAL AND METHODS: A Prospective Cross-sectional observational study conducted among the medical record officers (MROs) and multifunctional computer terminal technicians (MCTTs) working at counters. The prevalence of voice disorders in the study population was evaluated by voice analysis and stroboscopy. Meetings were conducted in the department describing the study and volunteers were recruited after consent. Detailed history and ear, nose and throat examination of the subjects were done. Following which participants underwent voice analysis which included phonation duration assessment, voice profile analysis, GRBAS scale, objective analysis using PRAAT software, self-evaluation using Voice Disorder Outcome Profile and stroboscopy. RESULTS: A total of 74 MROs and MCTTs were recruited in the study, with 73% males and 27% females. The age group of the study population ranged between 25 and 55 years. According to the quality of voice 43%, GRBAS scale 47% and VDOP 74% of the study population were found to have voice disorders and 96% of the 26 who volunteered stroboscopic showed pathological changes. Habitual frequent throat clearing showed statistical correlation with the prevalence of voice disorder suggestive of strong statistical correlation, based on the p value of voice quality (0.006); GRBAS scale (0.011) and VDOP (0.014). Screaming or shouting in causing voice disorder showed statistically significant correlation based p value of voice quality (0.008) and VDOP (0.005). The percentage of participants consuming less than 3 liters of water per day was 33.8% which correlation with incidence of voice disorder according to the p value of GRBAS (0.019). CONCLUSION: The study concluded that there is a high prevalence rate of voice disorders among hospital support staff. The significant risk factors for voice disorders isolated from the study were frequent clearing of throat, screaming or shouting and inadequate water intake. Though very few among the subjects perceived voice related difficulties, a significant percentage of the study population had underlying voice pathologies that required intervention, but were unaware.
