Methods In May 2024,a cross-sectional study was conducted to select 275 medical staff in cardiology department from 12 tertiary general hospitals in Sichuan Province as the survey subjects. The organizational culture scale,the transformational leadership style scale and the health productivity impairment scale were used for investigation,and the data were analyzed. Results The score of organizational culture of 275 medical staff in cardiology department was （85.04±11.13）points,the score of transformational leadership style was （59.31±9.13）points,the score of health productivity impairment was （16.89±5.55）points.Univariate analysis showed that there were statistically significant differences in the scores of impaired health productivity of medical staff in cardiology department with different gender,age,job category,education level,professional title,establishment or not,night shift,health status,sleep quality and willingness to work with disease（all P<0.05）.Pearson correlation analysis showed that the score of health productivity impairment of medical staff in tertiary comprehensive cardiology department were negatively correlated with organizational culture（r=-0.265--0.687,all P<0.05）,and negatively correlated with the score of transformational leadership（r=-0.214--0.671,all P<0.05）.Multivariate hierarchical regression analysis showed that night shift,health status,sleep quality,organizational culture and transformational leadership style were the main influencing factors of health productivity impairment of medical staff in cardiology department of tertiary general hospital. Among them,organizational culture and transformational leadership style had significant predictive effect on health productivity impairment（β=-0.232,-0.296,both P<0.05）,which independently explained 11.5% of the influencing factors of health productivity impairment. Conclusion The health productivity of medical staff in cardiology department of tertiary hospitals is at a medium level. Organizational culture and transformational leadership style are significantly related to the health productivity impairment,which are important protection resources. Managers should pay attention to the health productivity impairment status of medical staff,create a positive workplace spiritual and cultural atmosphere,and advocate transformational leadership style,so as to reduce the health productivity impairment of medical staff.
