Computerized Assessment of Readiness (Focos/Prontos System) and Its Multifactor Screening for Worker’s Fatigue and Productivity: A Case-Control and Cross-sectional Study

We present here a brief review of what has been published about fatigue, highlighting its multifactorial nature and the lack of objective markers that make it difficult to establish a consensus on measurement methods and present the Computerized Evaluation of Work Readiness (FOCOS/Prontos System), aiming to assess the correlation between the computerized assessment performance and signs of fatigue, using the Chalder instrument. The study applied the Chalder Fatigue Scale to 552 employees of a Brazilian mining company, with a final sample consisting of 334 individuals divided into a 'clinical group' (G1) with signs of fatigue and a 'control group' (G0) without fatigue. The study aimed to analyze readiness profiles between the clinical and control groups using statistical tests like the Mann-Whitney U-test and Welch's t-test, with significance set at p-value
