This is descriptive research aimed at identifying the factors for nursing productivity in nurses at a tertiary hospital. The data were collected from a survey conducted in 257 nurses at a single hospital in Seoul from May to June 2020. The collected data were analyzed through t-test, ANOVA, Scheffe test, Pearson’s correlation, and multiple regression analysis by using an SPSS 25.0 program. The total score was an average of 25.40±5.49 (range: 6-36) for gratitude disposition, 65.15±9.18 (range: 21-105) for job satisfaction, 87.64±12.05 (range: 23-115) for nursing performance, and 35.68±6.79 (range: 0-45) for nursing productivity. Nursing productivity was positively correlated with gratitude disposition (r=.219, p<.001), job satisfaction (r=.440, p<.001), and nursing performance (r=.494, p<.001). Nursing productivity was affected by gratitude disposition (β=.144), nursing performance (β=.394), and job satisfaction (β=.278). On the basis of these results, it is necessary to develop and apply education programs aimed at promoting work productivity for nursing manpower.
