Computer vision syndrome in healthcare workers using video display terminals: an exploration of the risk factors.

AIMS: To estimate the prevalence of computer vision syndrome (CVS) in healthcare workers and its relationship to video display terminal (VDT) exposure, sociodemographic, optical correction and work characteristics, and to analyse whether there are differences among occupational groups. DESIGN: Cross-sectional study. METHODS: A sample of 1179 physicians and surgeons, nurses, and nursing assistants from two hospitals in Spain between January 2017 and February 2018 were invited to participate in this study. Of these, 622 workers from both hospitals were finally included. CVS was measured using a questionnaire, the CVS-Q© . Logistic regression was used to identify the factors associated with CVS. All the results were stratified by occupational group. RESULTS: The prevalence of CVS was 56.75% with nurses being the most affected occupational group (61.75%). It was associated significantly with female sex (aOR = 2.57; 95% CI 1.36-4.88) and morning shifts plus on-call (aOR = 2.33; 95% CI 1.11-4.88) in the physicians and surgeons group. Among the nurses, it was associated with female sex (aOR = 2.35; 95% CI 1.03-5.37), seniority between 10 and 20 years (aOR = 2.17; 95% CI 1.03-4.59), VDT exposure at work of 2-4 h/day (aOR = 6.14; 95% CI 1.08-35.02), VDT exposure at work >4 h/day (aOR = 7.14; 95% CI 1.29-39.62) and self-perception that using the software application was not easy (aOR = 2.49; 95% CI 1.23-5.01). CONCLUSIONS: A high prevalence of CVS among healthcare workers was observed. The risk factors that increased the likelihood of suffering from this syndrome depended on the occupation. IMPACT: The findings may be used as a reference for occupational health services to implement specific preventive measures to reduce CVS for each occupational group. Such measures should consider both individual factors and the working conditions.

Prediction of Computer Vision Syndrome in Health Personnel by Means of Genetic Algorithms and Binary Regression Trees.

One of the major consequences of the digital revolution has been the increase in the use of electronic devices in health services. Despite their remarkable advantages, though, the use of computers and other visual display terminals for a prolonged time may have negative effects on vision, leading to a greater risk of Computer Vision Syndrome (CVS) among their users. In this study, the importance of ocular and visual symptoms related to CVS was evaluated, and the factors associated with CVS were studied, with the help of an algorithm based on regression trees and genetic algorithms. The performance of this proposed model was also tested to check its ability to predict how prone a worker is to suffering from CVS. The findings of the present research confirm a high prevalence of CVS in healthcare workers, and associate CVS with a longer duration of occupation and higher daily computer usage.

Eficacia de la vigilancia de la salud en población laboral para la detección y prevención de factores de riesgo cardiovascular y su relación con el tipo de trabajo / Effectivenes of surveillance of the workers health to detect and prevent cardiovascular risk factors and its relation with the type of work

Objetivos: Conocer la prevalencia de factores de riesgo cardiovascular en población laboral, medir el nivel de riesgo según el tipo de trabajo y analizar la importancia del examen de salud en la prevención del riesgo cardiovascular. Material y Métodos: Se incluyó a 453 trabajadores en los que se realizo un examen de salud laboral, donde cumplimentaron una cuestionario estructurado y se recogieron parámetros antropométricos y analíticos. De los 453 trabajadores, 177 acudían por primera vez, tratándose de vigilancia de la salud periódica para el resto. Para analizar la evolución de factores de riesgo cardiovascular se revisó la historia médico-laboral previa de estos 276 trabajadores. Resultados. El grupo de trabajadores manuales fue el que presentó unmayor acumulo de factores de riesgo, observando diferencias significativas para las variables presión arterial e índice de masa corporal. El tabaquismo fue el actor que mejor respondió en la sucesión de exámenes de salud. Conclusiones: Los resultados sugieren un buen comportamiento de la prevención secundaria de los factores estudiados y la necesidad de un esfuerzo mayor en prevención primaria (AU)

Objective: To determine the prevalence of cardiovascular risk factors in a simple of workers, to measure the level of risk according to type of work and to analyze the importance of routine medical check-up in the prevention of cardiovascular risk. Material y Methods: 453 workers who came for medical check-up were included. A structures questionnaire was filled and anthropometric and analytics parameters were obtained. 177 of the 453 workers, attended an initial medical check-up, and for the 276 remaining workers, was a routine medical check-up. Previous medical histories of these 276 workers were reviewed to analyze the evolutionof cardiovascular risk factors. Results: The majority of risk factors were observed in the group of manual workers. We have noticed a statistically remarkable different between different group of workers concerning blood pressure and B.M.I Smoking was the factor with better improvement through medical check-up. Conclusions. Results suggest a good behavior of secondary prevention of the factors studied and the need for grater efforts in primary prevention (AU)
