Identificación, medición y evaluación de factores de riesgo en los puestos de trabajo de los servidores públicos que utilizan pantallas de visualización de datos (PVD) en las oficinas de la Universidad Regional Amazónica Ikiam

Abstract

A cross-sectional research with a universe of 120 public servants (administrative staff, faculty members and employees) was carried out. According to the technical criteria of the National Institute for Health and Safety at the Workplace (INSST in Spanish), identified 55 people as VDU (Visual Display Units) users, only 47 of them are still part of this research (30 job positions with similar designations). During the general risk assessment of the university, it was determined that tolerable risk prevails (45%), followed by trivial risk (42%), moderate risk (13%), while important and intolerable risks have not been identified (0%). Psychosocial hazard factors (30%) prevail over ergonomic hazards (25%), mechanical hazards (25%), biological hazards (13%), physical hazards (3.6%), chemical hazards (3%) and major accidents (0.4%). In general, job positions such as: Cleaning Assistants (26), Laboratory Technicians (17), Experts in Engagement and Social Welfare (17), Dentists (15), Maintenance and Operations Experts (15) and Physicians (14) rank among the five occupations that are most exposed to work-related risk factors. The results of the Nordic Kuorinka questionnaire concluded that the neck (87.23%) (n = 41) is the body part that causes the most discomfort to VDU users, followed by the dorsal or lumbar area (57.45%) (n = 27), both shoulders (34.04%) (n = 16), right wrist or hand (29.79%) (n = 14), and right elbow or forearm (19.15%) (n = 9). According to the Rapid Office Strain Assessment (ROSA), high risk prevails (level 2) (53.3%), followed by improvable risk (level 1) (40%), and a remarkably high risk (level 3) (6.7%). At this level, we can find the Administrative Assistant and Financial Specialist positions, with a final ROSA score of 6. Finally, an Occupational Risk Prevention Plan (PPRL in Spanish) was proposed for VDU users, in order to reduce the probability of occurrence of professional or occupational diseases and occupational accidents.
