RESUMO
OBJECTIVES: To investigate the medical costs and productivity costs of voice symptoms among teachers and to assess the contribution of the characteristics of voice symptoms, sociodemographic characteristics, health conditions, and work-related factors to these costs. STUDY DESIGN: This is a cross-sectional study. METHODS: In 2012, we conducted a longitudinal study in 12 public schools in Bogotá D.C., Colombia. This study is focused on cross-sectional results obtained in the first stage of the data collection process. Participants filled out a questionnaire on sociodemographics, voice symptoms, work-related conditions, use of health care, productivity loss at work, and sickness absence. Multiple logistic regression analysis was used to explore associations among health care use, voice-related absenteeism and productivity loss with duration and severity of voice symptoms, sociodemographic characteristics, health conditions, and work-related factors. RESULTS: In total, 621 Colombian teachers participated in this research, 438 of whom had self-reported voice complaints and who therefore made up the study population. Total medical costs and productivity costs due to presence of voice symptoms among teachers with voice complaints equaled around 37% of their monthly wage. Approximately, 3% of the costs were direct costs for health care use, and 97% were indirect costs for productivity losses. Severity of voice symptoms was significantly associated with health care use and absenteeism. CONCLUSIONS: Voice symptoms among teachers have important economic consequences because of health care use, voice-related absenteeism, and productivity loss at work.
