Objectives:To systematically evaluate effectiveness and safety of early warning and prevention of hospital-acquired venous thromboembolism (HAT) .Methods:Computers were used to search PubMed, Embase, Web of Science, CINAHL, Cochrane Central Register of Controlled Trials, China Biology Medicine disc, CNKI and Wanfang Database. RCTs of early warning and prevention HAT at home and abroad was searched systematically and the retrieval time was from the establishment of databases to June 1, 2020. Two researchers independently screened the literature according to the literature inclusion and exclusion criteria, extracted data and evaluated the risk of bias in the study. RevMan 5.3 software was used to conduct Meta-analysis of the incidences of HAT, pulmonary thromboembolism (PTE) , deep vein thrombosis (DVT) , bleeding and prevention rate of HAT.Results:A total of 8 articles were included. Results of Meta-analysis showed that the incidence of PTE in the early-warning group ( RR=0.69, 95% CI 0.53-0.91, P=0.009) and the prevention rate of HAT ( RR=1.45, 95% CI 1.14-1.84, P < 0.001) were statistically significantly different from those in the non-warning group. However, the incidences of HAT ( RR=0.89, 95% CI 0.68-1.16, P=0.380) , DVT ( RR=0.99, 95% CI 0.76-1.29, P=0.970) and bleeding ( RR=0.95, 95% CI 0.81-1.11, P=0.500) had no statistically significant difference between the two groups. HAT prevention was defined as a subgroup of appropriate prevention. There was no statistically significant difference in the HAT prevention rate of patients between the two groups ( RR=1.01, 95% CI 0.95-1.07, P=0.810) . In the subgroup that did not describe in detail whether prevention was appropriate, the HAT prevention rate in the early-warning group was higher than that in the non-early warning group, and the difference was statistically significant ( RR=2.28, 95% CI 2.09-2.49, P<0.001) . Conclusions:Early warning can reduce the incidence of PTE by increasing the prevention rate of HAT without increasing the incidence of bleeding, but it has no significant effect on the incidences of HAT and DVT. Limited by the quantity and quality of the included studies, the above conclusions need to be verified by more high-quality studies.

Objective:To explore the research hotspots and evolution of Common Sense Model (CSM) , in order to provide a clearer research direction for nursing workers to improve health-related outcomes of patients from the perspective of health psychology.Methods:English literature related to CSM was searched in Web of Science Core Collection database from January 1, 1985 to December 31, 2020. VOSviewer 1.6.15 software was used to draw a visual map of keyword density, clustering and time distribution and CiteSpace 5.6.R5 software was used to detect emerging words.Results:Finally, 364 papers were included, and the annual publication volume and citation frequency of CSM research showed an overall upward trend. CSM research hotspots mainly focused on interpreting or intervening patients' perception of disease, in order to improve self-management of patients, compliance, quality of life, anxiety, depression and psychological distress. The research objects were mainly cancer patients. Social support and psychological distress were explored based on the CSM framework and using Meta-analysis methods to summarize may be an important part of future CSM research work. CSM research was currently in the stage of summarizing and deepening after theoretical perfection and extensive application.Conclusions:The annual publication volume and citation frequency of CSM research have generally shown an upward trend, which has attracted the attention of domestic scholars, but there is still a big gap compared with foreign countries. Future research can explore the role of social support in the process of individual self-regulation after illness and explore effective methods to intervene in patients' negative disease perception through Meta-analysis, in order to improve patients' health outcomes.

Objective:To search for and summarize the best evidence on non-pharmacological interventions for orthostatic hypotension in patients with Parkinson disease.Methods:Based on the 6S model, the relevant guidelines, clinical decisions, evidence summaries, systematic reviews and expert consensus on non-pharmacological interventions for orthostatic hypotension in Parkinson disease patients were systematically retrieved from domestic and foreign databases. The search time was from the establishment of the database to December 2022. Two researchers independently screened the literature, evaluated the quality of the included literature, and extracted and summarized evidence that met the quality standards.Results:A total of 15 articles were included, including 4 guidelines, 2 clinical decision-making articles, 1 evidence summary article, 3 systematic evaluations and 5 expert consensus articles. A total of 24 pieces of best evidence were summarized from 7 aspects, including purpose, evaluation, capacity intervention, exercise intervention, posture intervention, physical intervention, health education and support.Conclusions:The best evidence on non-pharmacological intervention for orthostatic hypotension in patients with Parkinson disease can provide a reference for the practice of clinical medical staffs. It is suggested to apply the best evidence in combination with the patient's condition, preference and clinical environment, so as to reduce the incidence of orthostatic hypotension in patients with Parkinson disease and to ensure the safety of patients.
