We have analysed the impact of psychosocial risks on the health of hospital staff, in an attempt to determine whether there is a correlation between the risk level assessed and the number of days of medical absenteeism through diseases with psychosocial stress as a contributory or aggravating factor. There is a strong correlation between the risk level assessed by sectors of activity and the number of days of medical absenteeism through diseases caused or favoured, potentially aggravated by occupational psychosocial stress.
