Objective To retrieve,evaluate and summarize the best evidence on the management of ocular complications in intensive care patients ventilated in prone position,and to provide references for clinical practice.Methods Evidence on management of ocular complications in intensive care patients ventilated in prone position was systemically retrieved in the guideline websites,professional association websites and databases,such as the BMJ Best Practice,UpToDate,Cochrane Library,Joanna Briggs Institute,PubMed,Web of Science,Science Direct,Embase,CNKI,Wanfang and other databases,including guidelines,clinical decisions,evidence summaries,expert consensuses,group standards,systematic reviews and scoping reviews,published from January 2013 to June 2023.The guidelines were individually evaluated by 4 researchers,and the remaining literature was individually evaluated by 2 researchers.The literature that met the criteria was extracted and graded.Results A total of 15 articles were involved,including 6 guidelines,2 clinical decisions,2 evidence summaries,3 systematic reviews,1 scoping review and 1 group standard.Finally,6 evidence topics and 16 pieces of best evidence were formed,including organization and training,risk identification,eye assessment,eye protection,position management and regular observation.Conclusion This study summarized the best evidence on the management of ocular complications in intensive care patients ventilated in prone position.In the application,the best evidence should be selected according to the clinical situation,so as to reduce the incidence of ocular complications and improve the quality of life of patients.

【Objective】 To explore the effect of mobile transfusion closed-loop information system in the whole process management of clinical blood transfusion. 【Methods】 The hospital information system (HIS) of Soochow Hospital affiliated to Nanjing Medical University was integrated with the blood information system (BIS) and personal digital assistant (PDA) to build a closed-loop transfusion management process to ensure the safety of clinical blood use. From May 2021 to April 2022, 1 395 patients who were admitted to our hospital for blood transfusion therapy were studied. Among them, 632 patients from May to October 2021 (before the implementation of closed-loop management) were the control group, and 763 patients from November 2021 to April 2022 (after the implementation of closed-loop management) were the observation group. Before and after the implementation of closed-loop management, we compared the implementation rate of double-checking before blood sample collection, rate of transfusion within 30 min after blood issuing, implementation rate of double-checking of bedside transfusion, situation of patrol every 15 minutes, rate of transfusion completed within 4 h, rate of nursing documentation standardization, so as to evaluate the improvement effect of the whole process of transfusion management. 【Results】 The implementation rate of double-checking before blood sample collection was 99.48%(759/763) in the observation group and 93.99%(594/632) in the control group; the transfusion rate within 30 min after blood issuing was 95.02%(725/763) in the observation group and 91.46%(578/632) in the control group; the implementation rate of double-checking of bedside transfusion was 100%(763/763) in the observation group and 95.73%(605/632) in the control group; the complete rate of patrol every 15-min was 94.36%(720/763) in the observation group and 90.35%(571/632) in the control group; the completion rate of transfusion within 4 h was 95.81%(731/763) in the observation group and 92.25%(583/632) in the control group; the rate of nursing paperwork standardization was 98.03%(748/763) in the observation group and 81.80%(517/632) in the control group, and the difference between the two groups was statistically significant (P<0.05). 【Conclusion】 The mobile transfusion closed-loop information system can realize the whole process management of clinical blood transfusion, effectively improve the standardization of blood transfusion and transfusion documents, and guarantee the safety of clinical blood transfusion.
