Work capacity, sociodemographic and work characteristics of nurses at a university hospital.

This cross-sectional study evaluated the work capacity of 195 nurses at a university hospital, from a calculation of sample size with a Confidence Interval (CI) of 95%. The data was collected by means of the Work Capacity Index (WCI) instrument and analyzed by statistical analysis. 94.5% of the sample was made up of women; the average age was of 42.6 years (sd=8.5); 66.5% had partners and 76.7% were educated to post-graduate level. 36.0% worked the night shift; 28.4% the morning shift and 20.8% the afternoon shift. The average score given to work capacity was Good (41.8 points) and there was a significant correlation with pay (p-value<0.05), satisfaction with workplace (p-value=0.001) and feeling valued by the institution (p-value=0.003). The group which carried out family activities showed higher scores in the WCI compared to those who did not (p-value=0.009). The nurses presented differing sociodemographic and work aspects, with a high capacity for work.
