Objective To form an expert consensus on the implementation and removal of psychiatric protective restraints,and to standardize the related contents of the implementation and removal of psychiatric protective restraints. Methods According to the level of evidence,the evidence-based method was used to retrieve,evaluate and summarize the evidence in the field. The recommendations and research conclusions for the implementation and removal of the psychiatric medical protective restraints were extracted,and the rough consensus was formed. Through 2 rounds of enquiry and 2 experts discussion meetings,the final version of the consensus was formed by combining with the expert opinions,adjusting,modifying and perfecting the first draft. Results The positive coefficients of experts in the 2 rounds of correspondence consultation were 100%;the degree of authority of experts was 0.90;the mean value of importance of each index was>3.5,and the coefficient of variation was less than 0.25,and the expert Kendall harmony coefficient was 0.146 and 0.166,respectively （all P<0.01）. Finally,a consensus was reached on the recommendation of 10 parts,including the application group of psychiatric restraints,premise and principle,objective,key points of assessment,basic requirements,record sheet,flow chart,intervention strategies in the implementation process,ethical issues and risks,and suggestions. Conclusion The consensus provides guidance for the practice of psychiatric protective restraints and makes psychiatric restraints more standardized.

Objective To form an expert consensus on suicide nursing interventions for inpatients with depression in psychiatric departments,standardize the contents of suicide nursing interventions for depression patients in psychiatric departments. Methods Evidence-based methods and literature analysis were used to extract recommendations and research conclusions of suicide nursing interventions for inpatients with depression,and the consensus draft was formed. After 2 rounds of expert letter consultation and 2 expert discussions,the draft was adjusted,modified and improved,and the final draft of the consensus was formed. Results The positive coefficients of the experts in 2 rounds of letter consultation were 100%;the authority degree of the experts was 0.924;the mean values of importance of each index were >3.5 points;the coefficient of variation was<0.25;the Kendall harmony coefficients of the experts were 0.182 and 0.260,respectively（P<0.01）. Finally,the operational definition,suicide risk assessment,intervention form and time,theoretical basis of intervention,general principles of intervention,suicide impression intervention,suicidal behavior intervention,key points of intervention in special populations,evaluation of intervention effect and post-discharge evaluation of suicide care in hospitalized patients with depression were analyzed. A total of 11 components of the health education program were agreed upon. Conclusion The consensus provides the guidance for the suicide nursing interventions of psychiatric inpatients with depression,so that the suicide nursing intervention of psychiatric inpatients with depression is more standardized.

Objective To explore the cross-lagged effect between cognitive function and depression in the elderly in communities.Methods Based on the longitudinal study,the cross-lagged panel model was used to analyze the cognitive function and depression performance of elderly people in 2013 and 2017. The cross-lagged effect was analyzed by the structural equation model.Results ①The results of ANOVA showed that the cognitive function and the depressive behavior have a decreasing trend with time,and the decline level of women is more severe;②The correlation analysis showed that the baseline cognitive function score was positively correlated with the follow-up cognitive function score（r=0.632,P<0.001）;the baseline depression score was positively correlated with the follow-up depression score（r=0.485,P<0.001）;the follow-up cognitive function score was negatively correlated with the follow-up depression score（r=-0.166,P=0.002）;the baseline cognitive function score did not have correlation with the baseline and follow-up depression scores（P>0.05）;③The results of cross-lagged regression analysis showed that the cognition at baseline positively predicted cognition at follow-up（ β=0.718,P<0.001） and depressive symptoms at follow-up（ β=-0.133,P=0.004）;the depressive symptoms at baseline positively predicted those at follow-up（ β=0.518,P<0.001）.But there was no significant predicted effect between cognition at baseline and depressive symptoms at baseline（ β=-0.155,P=0.006）.Conclusion The baseline cognitive function level of the elderly in the community have a predictive effect on the follow-up of depression,while the baseline depression level have no predictive effect on the follow-up of cognitive function,and the relationship between the cognition and depression should be further explored.
