Objective To systematically evaluate the impact of cough enhancement techniques on weaning outcomes in adult patients under mechanical ventilation(MV).Methods Databases from the inception to 15th November,2024 were searched for randomised controlled trials(RCTs)on cough enhancement technique in MV patients.The searched databases were CNKI,Wanfang Data base,SinoMed,Vip,PubMed,Web of Science,Cochrane Library,Embase,and CINAHL.Literature and evidence quality were evaluated using Cochrane's evaluation tool for intervention research and the GRADE system,and data were extracted and analysed via Meta-analysis with Review Manager 5.3.Results A total of 27 studies were included,involving 2,322 patients(1,169 in the trial group and 1,153 in the control group).Compared with the control group,the trial group had shorter time of mechanical ventilation[MD=-1.40,95%CI(-1.83,-0.97),P<0.001],lower weaning failure rate[OR=0.48,95%CI(0.27,0.85),P=0.01],higher oxygenation index[MD=35.48,95%CI(21.53,49.43),P<0.001],lower pulmonary atelectasis incidence[OR=0.30,95%CI(0.18,0.49),P<0.001],greater sputum volume[MD=1.88,95%CI(0.76,3.01),P=0.001],shorter ICU stay[MD=-1.90,95%CI(-2.95,-0.85),P<0.001]and lower serum procalcitonin(PCT)[MD=-0.89,95%CI(-1.64,-0.14),P=0.02],all with statistically significant differences.However,there was no significant difference in the ventilator-associated pneumonia(VAP)between the two groups[OR=0.54,95%CI(0.21,1.35),P=0.19].Conclusion Cough enhancement techniques promote sputum discharge,improve infection and oxygenation,shorten mechanical ventilation and ICU stay,reduce weaning failure and atelectasis rates in MV patients.Further studies are required to reduce the incidence of VAP.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective:To standardize the management of auditory hallucination symptoms in inpatients with mental illness and develop an expert consensus on the management of auditory hallucinations in hospitalized psychiatric patients.Methods:From March 2023 to July 2023, the Mental Health Committee of the Chinese Nursing Association focused on the key issues in the management of auditory hallucinations symptoms in inpatients with mental illness, based on clinical practice, using literature analysis combined with the work experience of mental health experts, and formed the first draft of the expert consensus on the management of auditory hallucinations in inpatients with mental illness (hereinafter referred to as the consensus). Through 3 rounds of expert consultation and 3 rounds of expert demonstration meeting, the draft was adjusted, revised, and improved.Results:37 experts were included in the Delphi expert consultation, 1 male and 36 females with 39-67(51.48 ± 6.61) years old. The positive coefficients of experts in 3 rounds of Delphi expert consultations were all 100%, and the degrees of expert authority were 0.924, 0.938 and 0.949, respectively. The average importance value of each item was higher than 4.00, the variation coefficient of each item was less than 0.25. The Kendall harmony coefficient of the experts were 0.179, 0.195 and 0.198, respectively (all P<0.05). There were 15, 12, 12 experts in the first, seeond, third rounds of expert demonstration meeting. Finally, a consensus was reached on the recommendation of 4 parts, included auditory hallucination assessment, management format, symptom management implementation, and precautions. Conclusions:The consensus covers all parts of the management of auditory hallucination symptoms in hospitalized patients with mental disorders, which is practical and scientific. It is helpful to guide mental health professionals to standardize the management of auditory hallucination symptoms, improve the quality of nursing and ensure the safety of patients.
