Productivity Loss and Predictive Factors Among Visually Impaired Adults in Tertiary Eye Care Centers, Addis Ababa, Ethiopia: A Dual-Center Cross-Sectional Study

Abstract

Visual impairment has a profound impact on loss of economy and productivity, which can impair health-related quality of life. The purpose of this study was to determine productivity loss and its predictive factors among adults with visual impairment in Addis Ababa tertiary eye care centers, Ethiopia. An institution-based cross-sectional study was conducted between February and July 30, 2021. A total of 425 samples were retrieved using systematic random sampling. Data collection included socio-demographic information, employment status, job absenteeism, presenteeism and reduced work participation. Analysis was done by SPSS version 23, and binary logistic regression was employed for statistical analysis. P-values less than 0.05 were used to state significant associations between dependent and outcome variables. A total of 416 study participants were involved in the study, with a response rate of 97.88%. The mean age was 48±14.3 years. The total productivity loss was $775,325.51, with a median of $358.02. Maximum productivity loss was contributed by reduced workforce participation, which was about $746,337.45, with a median of $1,432.10. Regarding predictor factors, gender, monthly income, degree and duration of visual impairment and support of family to get job were statistically associated with high productivity loss. In general, the current study revealed that there is a profound annual loss of productivity due to visual impairment. The predictor factors for higher productivity loss were gender, monthly income, degree of visual impairment, duration of visual impairment and presence of support from family to get job or achieve better performance on job activities. Rehabilitation for visually impaired adults is recommended to enhance their quality of life by increasing their workplace participation to the maximum potential.
