Objective To analyze the current situation and latent profiles of nurses’ voice behavior in nurses，and explore the influencing factors of different types. Methods Through convenience sampling，812 nurses who worked in tertiary hospitals from 5 cities in Guangdong Province during April 2022 to June 2022 were recruited. The demographic questionnaire，the Voice Behavior Scale，the Humble Leadership Scale，and the Team Psychological Safety Climate Scale were used for investigation. Latent profile analysis was used to explore the latent profiles of nurses’ voice behavior. The influencing factors of latent profiles were identified by multivariate Logistic regression. Results The total score of the voice behavior in 812 nurses is（37.04±5.88）. Voice behaviors in nurses is divided into 3 latent classes，namely “conservation group”（27.83%），“balanced-risky group”（61.95%），and “the challenge group”（10.22%）. The influencing factors include recruitment type，whether to assist in department management，humble leadership，team psychological safety climate（all P<0.05）. Conclusion The level of nurses’ voice behavior is upper medium with heterogeneity，which can be divided into 3 latent profiles. Nurses managers should focus on nurses with conservation group and balanced-risky group and conduct early targeted prevention and care according to characteristics and influencing factors of different latent profile.

Objective To investigate the influencing factors of compassion fatigue（CF） among nurses in maternity hospitals,and then to further explore the impact path of factors. Methods 715 nurses in maternity hospitals from Jiangsu were investigated by the cross-sectional survey. A self-developed questionnaire,the Five-Factor Inventory,the Social Support Rate Scale,the Psychological Capital Questionnaire-Revision,and the Compassion Fatigue Scale were adopted to collect data. Results The number of children,personality of neuroticism and agreeableness,social support,and psychological capital are the influencing factors of CF（P<0.05）,while professional titles,length of services,labor relations,personality of extraversion and openness,social support and psychological capital influence compassion satisfaction（CS）（P<0.05）. In structural equation model,the indirect effects of neuroticism on CF or CS existed（ES=0.062,-0.420）. Social support and psychological capital play a partially mediating role in neuroticism and CF（ES=0.017）,accounting for 27.42% of the total indirect effects. They also play a completely mediating role in neuroticism and CS（ES=-0.112）,accounting for 26.67%. Positive personality had a significant indirect effect on CF or CS（ES=-0.158,0.623）,and social support and psychological capital serve as a completely mediating role between them （ES=-0.028,0.102）,accounting for 17.72% or 16.37% of the total indirect effects. Conclusion Nursing managers should take effective measures tailored to personality traits to help nurses meet high levels of social support and psychological capital,so as to promote CS and reduce CF.

Objective To investigate the current situation of central venous catheter closure for blood purification patients in ICUs,and to compare the differences between different hospitals. Methods In September 2020,the convenience sampling method was used to conduct an online survey of 228 ICU wards in 117 hospitals of 23 provinces. The survey included general information and the current status of the central venous catheter closure for blood purification patients in the ICUs. Results A total of 222 valid questionnaires were collected. Heparin was the most commonly used sealing liquid,followed by citric acid,and urokinase was the least. The concentration of heparin was mainly 1 250 U/ml,and the concentration of citric acid was mainly 4%. The dosage of the sealing solution was mostly 1 times the volume of the catheter;the frequency of sealing is more after each dialysis;the sealing method is mainly positive pressure combined with pulse sealing. The catheter was withdrawn before sealed;the number of withdrawals was mostly 2 times,and the withdrawal volume per time was mostly twice the catheter capacity. There are significant differences in terms of the concentration,dosage,frequency of sealing,number of withdrawals,withdrawal volume per time between tertiary hospitals and non-tertiary hospitals（all P<0.05）. Conclusion The selection,concentration,dosage,frequency of the sealing of the central venous catheter for blood purification in ICUs are not the same. It is recommended to formulate the nursing standards for sealing the central venous catheter for blood purification patients in the ICU to standardize the reasonable and effective sealing of the tube by clinical nurses.
