Objective To investigate anxiety of clinicians in tertiary hospitals,and discuss the fac-tors that influence clinicians'anxiety in order to provide reference for further effective intervention measures. Methods 427 clinicians from various departments in tertiary hospitals selected by cluster sampling method were investigate by self-rating anxiety scale ( SAS) .Statistical software SPSS 17.0 was used to analyze data for multivariate logistic regression analysis of its relevant influencing factors.Results 38.2%of the clini-cians had anxiety symptoms (55.0%was mild anxiety,26.1%was moderate anxiety,18.9%was severe anxi-ety) .Factors like education (χ2=7.3, P=0.03) ,job title (χ2=53.24, P<0.01) ,divisions (χ2=46.46, P<0.01) ,work experience (χ2=9.78, P=0.04) ,work overtime (χ2=4.29, P=0.03) ,worry of medical mal-practice (χ2=9.54, P<0.01),doctor-patient relationship tension (χ2=7.50, P<0.01),fear for personal safety (χ2=10.27, P<0.01) ,job promotion competition (χ2=11.40, P<0.01) ,labor and payment situation (χ2=6.36, P=0.01) ,colleagues'understanding and support (χ2=15.77, P=0.01) ,work environment (χ2=21.85, P<0.01) and leaders'attention (χ2=7.17, P=0.01) had significant differences between anxiety and non-anxiety clinicians.Multivariate logistic regression analysis revealed that factors like divisions ( com-pared with internal medicine,OB&GYNβ=0.98,surgeryβ=0.95,pediatricsβ=0.86,emergencyβ=0.69) , work overtime (β=0.18),fear for personal safety (β=0.86),fear of medical malpractice (β=0.79) and doctor-patient relationship tension (β=0.28) had a negative impact on anxiety,while factors like education ( compared with bachelors,mastersβ=-1.38,doctorsβ=-1.65) ,job title ( compared with primary,intermedi-ateβ=-0.33,highβ=-0.45,advancedβ=-0.59) ,work experience (β=-0.18 ) and work environment (β=-0.32) were protective factors.Conclusion There is a certain degree of anxiety among clinicians in tertiary hospitals,resulting in a heavy psychological burden on them.Active measures should be taken to improve the clinicians'psychological health.
