Work process and its effects on the health of nursing staff at the National Institute of Rehabilitation / Proceso de trabajo y sus efectos en la salud del personal de enfermería del Instituto Nacional de Rehabilitación.

Resumen

Introduction: The work process is a key determinant of the health of nursing staff, who are systematically exposed to risks and demands stemming from how their tasks are organized. In Mexico, the failure to ratify ILO Convention 149 exacerbates the lack of protection for this workforce. The objective was to analyze the relationship between the work process and its health effects on nursing staff at the National Rehabilitation Institute (INR). Method: A quantitative, cross-sectional, non-experimental study. A survey was conducted among 150 INR nurses (November 2025–March 2026) using the PROESSAT instrument (220 items, 5 variables). Analyses included descriptive statistics, bivariate analysis (prevalence ratios), and multivariate logistic regression (odds ratios). Results: The staff was predominantly female (85%) and exposed, on average, to 3.5 risks and 8.6 demands, with a morbidity rate of 5.12 presumptive diagnoses per worker. Biological and chemical risks (86%) were the most common, alongside demands for meticulousness (73%) and standing work (59%). Abusive supervision increased the likelihood of stress by a factor of 4.62. Discussion and conclusions: The identified burnout profile reflects structural determinants inherent to the healthcare work process, consistent with similar studies in Latin America. There is a need to transform patient workloads, supervision, ergonomic design, and wages, while strengthening the humanizing aspects of the work.
