Objective To summarize the risk factors of Post Intensive Care unit-family (PICS-F) mental dysfunction in family members, and to provide evidence for clinical medical staff to identify the risk factors of PICS-F mental dysfunction in advance.Methods Embase, PubMed, Cochrane Library, EBSCO, Web of Science, China Biomedical Database (CBM), CNKI, WanFang Database and VIP database were systematically searched from database establishment to May 2022. Literature on the risk factors of PICS-F mental dysfunction was included. After screening, extraction and quality evaluation, stata17.0 and RveMan5.4 were used to conduct meta-analysis on the incidence and risk factors of PICS-F.Results a total of 10692 subjects were included in 15 literatures. The incidence of pics-f mental dysfunction was 28% (95%CI 0.22 to 0.35). Subgroup analysis showed a 30% incidence in the United States and 27% in other countries. The incidence was 26% in cohort studies, and 43% in case-control and cross-sectional studies. The incidence was 26% at 3 months and 13% at 6 months. Meta-analysis results showed patient age (OR=1.06,95%CI 1.01 to 1.10), gender of family members (OR=4.07,95%CI 2.52 to 6.60) and relationship between family members and patients (OR=2.24,95%CI 1.00 to 4.99), family history of mental illness (OR=3.77,95%CI 1.58 to 8.97), length of ICU stay (OR=4.72,95%CI 2.10 to 10.64), and severity of disease (OR=5.95,95%CI 2.09 to 16.94), death (OR=1.90,95%CI 1.31 to 2.77), family education level (OR=1.07,95%CI 1.02 to 1.12) were the influencing factors of PICS-F psychological dysfunction. It is not clear whether the mode of admission and attendance at family meetings have an effect on PICS-F mental dysfunction.Conclusion The risk factors for PICS-F mental dysfunction are young age, female family member, spouse, history of mental illness, long ICU stay, severity of illness, death and low education level of family members. Clinical medical staff should pay attention to the above risk factors and take corresponding measures to reduce the incidence of PICS-F psychological dysfunction. Relevance to clinical practiceThe results of our meta-analysis have important consequences for ICU nurse managers. Our finding of high rate of PICS-F Psychological dysfunction among ICU patients. That more attention should be devoted to develop and apply prevention programs for ICU nurses to manage this global issue.

Background: Post-ICU syndrome has not been paid enough attention in Chinese medical institutions. Due to the large population base in my country, the number of people with post-ICU syndrome is also large, which has a great impact on the quality of life of patients in the later period. Objectives To develop and verify ICU nurses' knowledge, attitude and practice scale on post-ICU syndrome in critically ill patients, to provide a basis for the investigation of post-ICU syndrome status. Methods Using the principle of Knowledge, Attitude and Practice (KAP), a scale item database was created through literature review and semi-structured interviews. The scale was modified by Delphi expert correspondence method and pre-investigation. 451 ICU nurses were selected for formal investigation, and the reliability of the scale was evaluated degree test. Results A scale of knowledge, attitude, and practice of ICU nurses on post-ICU syndrome in critically ill patients was formed, In which the number of items in the three dimensions of knowledge, attitude, and practice were 11, 7, and 13, respectively. The Pearson correlation coefficient between dimensions and the total score of the scale ranged from 0.526 to 0.860, and the correlation coefficients between items and dimensions ranged from 0.517 to 0.921 (P＜0.001). Item content validity (I-CVI) ranged from 0.867 to 1, and scale content validity (S-CVI) is 0.989. Four common factors were extracted by exploratory factor analysis, and the cumulative variance explanation rate was 76.214%. Confirmatory factor analysis: Chi-square ratio of degrees of freedom (χ2/DF) =2.789, RMSEA=0.077, RMR=0.048, GFI=0.947, CFI=0.922, NFI=0.943, IFI=0.922, TLI=0.915. The Cronbach's alpha coefficients of the scale and dimension were 0.948, 0.976, 0.966, 0.910, split-half reliability = 0.951, and re-test reliability=0.927. Conclusion The reliability and validity of the scale meets the requirements of scale preparation, and can reflect the knowledge, belief, and behavior of ICU nurses in post-ICU syndrome.Relevance to clinical practice In this study, we developed a post-ICU syndrome knowledge, belief, and behavior survey to understand the current status of post-ICU syndrome knowledge, belief, and behavior among ICU nurses in my country.
