OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Objective To understand the nursing practice of prone position ventilation for patients with moderate to severe acute respiratory distress syndrome(ARDS)in intensive care unit(ICU)in Shandong province,so as to provide basis for standardizing the nursing practice process of prone position ventilation and carrying out training for hospitals.Methods A self-made questionnaire was used,and convenience sampling was adopted.From September 15th to November 5th,2023,ICU nurses were selected from various hospital levels in Shandong province to investigate the obstructive factors of prone ventilation implementation,the weak links in nursing practice and status,and the occurrence of complications.Results A total of 1 188 questionnaires were collected,of which 991 were valid.92.8%(920/991)of nurses had performed prone position ventilation.The biggest obstacle to the implementation of prone position ventilation was the complexity of patient treatments and multiple devices involved[74.6%(686/920)].Regarding the status of training,90.5%(897/991)of nurses had received training on prone position ventilation and 77.0%(763/991)of nurses felt that training was needed.As for pre-operation assessment,more than 80.0%of nurses evaluated patients'vital signs,airway and secretions and so on,among which the evaluation awareness of analgesia was the worst[81.6%(751/920)].As for the main points of implementation,only 14.0%(129/920)of nurses chose the opposite side of the most important pipeline as the turning direction;48.6%(447/920)of nurses chose the anti-Trendelenburg position;36.3%(334/920)of nurses chose to ventilate≥12 hours.Facial edema[81.7%(752/920)],skin pressure injury[78.9%(726/920)]and eye complication[75.8%(697/920)]were the top 3 most frequent complications.Conclusions ICU nurses'prone position ventilation practices were generally line with the nursing team standard for prone position of adult mechanically ventilated patients and the best evidence recommendation,and needs to be further standardized in aspects of turning direction,position management,ventilation duration,and enteral nutrition management.It is recommended that nursing managers at all levels of hospitals further improve the quality of nursing practice of prone position ventilation according to relevant evidence-based evidence and the actual situation of hospitals.

Objective:To observe the efficacy of arthroscopic LUtarjet procedure in the treatment of recurrent anterior shoulder dislocation combined with a glenoid bone defect.Methods:A retrospective study was conducted to analyze the data of 15 patients with recurrent anterior shoulder dislocation combined with a glenoid bone defect who had been treated by the arthroscopic LUtarjet procedure at Department of Orthopedics, The 928th Hospital of PLA Joint Logistics Support Force from September 2022 to November 2023. All patients were male, aged (25.0±1.9) years, involving 10 left and 5 right sides. The anterior fear test for the affected shoulder was positive in all cases before surgery, and the dislocations averaged (13.8±5.4) times. By comparing the three-dimensional CT scans of both shoulders before surgery, the severity of the glenoid bone defect was calculated as over 20% wider than the width of the healthy glenoid. The shoulder function was evaluated at 6 and 18 months after operation using the American Shoulder and Elbow Surgeons score (ASES), Rowe score, Walch-Duplay score and shoulder active range of motion. Comparisons were made between preoperation and postoperation. CT plain scan and three-dimensional reconstruction were used to evaluate the location and resorption of the transferred bone block of the coracoid process.Results:All patients were followed up for (19.8±1.1) months. The operation time for the 15 patients was (117.6±13.8) min. Re-dislocation occurred in none of the patients during postoperative follow-up. There was no significant difference in the flexion elevation, lateral external rotation, internal rotation or abduction 90° external rotation between preoperation, 6 months or 18 months after operation ( P>0.05). Respectively, the ASES, Rowe and Walch-Duplay scores were (93.3±2.3) points, (90.8±2.6) points, and (95.9±1.0) points at 18 months after operation, and (89.6±3.8) points, (84.5±2.7) points, and (87.2±3.9) points at 6 months after operation, showing significant improvements compared with the preoperative values [(70.9±6.1) points, (42.9±6.0) points, and (66.2±11.0) points] ( P<0.05). In the 3 patients whose immediately postoperative CT scan showed that their bone blocks were slightly lower in position, the bone blocks grew and shaped well at the last follow-up. The last follow-up observed partial bone resorption in one patient. Conclusion:In the treatment of recurrent anterior shoulder dislocation combined with a glenoid bone defect, the arthroscopic LUtarjet procedure can restore satisfactory stability of the shoulder joint, leading to good short- and mid-term efficacy.

Objective:To explore the impact of diabetes mellitus on perioperative myocardial injury and cardiac function recovery in patients undergoing off-pump coronary artery bypass grafting (CABG).Methods:The clinical data of 40 patients with coronary heart disease who underwent off-pump CABG in Changsha Central Hospital from 2015 to 2025 were retrospectively included. They were divided into the diabetes group (20 cases) and the control group (20 cases) according to whether they had type 2 diabetes mellitus. Myocardial injury markers (creatine kinase isoenzyme, troponin I, lactate dehydrogenase) before surgery, on the 1st and 3rd days after surgery and before discharge, as well as cardiac function indicators (B-type natriuretic peptide, left ventricular ejection fraction) before surgery and before discharge were compared between the two groups. The postoperative recovery speed (mechanical ventilation time, intensive care unit stay, vasoactive drug use time, postoperative hospital stay) was also compared between the two groups.Results:Before surgery, there were no statistically significant differences in myocardial injury markers and cardiac function indicators between the two groups (all P>0.05). On the 3rd day after surgery, lactate dehydrogenase in the diabetes group was significantly higher than that in the control group ( P<0.05), while there were no statistically significant differences in creatine kinase isoenzyme and troponin I between the two groups (all P>0.05). Before discharge, the levels of creatine kinase isoenzyme and B-type natriuretic peptide in the diabetes group were significantly higher than those in the control group (all P<0.05), and the left ventricular ejection fraction was significantly lower than that in the control group ( P<0.05). Compared with the control group, the diabetes group had significantly longer mechanical ventilation time, intensive care unit stay, and postoperative hospital stay (all P<0.05), but there was no statistically significant difference in the use time of vasoactive drugs ( P>0.05). Conclusions:For patients with coronary heart disease complicated with diabetes mellitus, their preoperative cardiac status is comparable to that of patients without diabetes mellitus, but they show a characteristic dynamic injury pattern after surgery: early elevation of lactate dehydrogenase suggests susceptibility to subcellular injury, and long-term abnormalities of creatine kinase isoenzyme, B-type natriuretic peptide, and decrease in left ventricular ejection fraction indicate myocardial repair disorders. Compared with patients without diabetes mellitus, those with diabetes mellitus require a longer recovery time after off-pump CABG, and targeted perioperative management strategies are urgently needed.

OBJECTIVE: To provide evidence for further reducing the incidence of central line-associated bloodstream infection (CLABSI) according to investigation of the prevention and control of CLABSI in intensive care unit (ICU) in Shandong Province. METHODS: The questionnaire was developed by experts from Shandong Critical Care Medical Quality Control Center, combining domestic and foreign guidelines, consensus and research. A convenient sampling method was used to recruit survey subjects online from October 11 to 31, 2023 in the province to investigate the management status of central venous catheter (CVC) in ICU units of secondary and above hospitals. RESULTS: A total of 201 valid data were collected, involving 186 hospitals in the province, with a total of 201 ICU units, mainly comprehensive ICU (91%). The beds in ICU units were mainly single rooms (89%) and triple rooms (79%), and the ratio of doctors to total beds was 0.54 : 1. The training on the knowledge and operation of intravascular catheter-associated bloodstream infection in each ICU unit was mainly irregular (49%), and 96% of the catheter operators were authorized by the hospital. In terms of CVC selection, 89% of ICU units used dual-chamber CVC, and 86% of ICU units used catheters without antibiotic coating. When selecting the placement site, for conventional CVC catheterization, 65% preferred subclavian vein. Femoral vein was preferred in 87% of ICU units undergoing continuous renal replacement therapy. 95% of ICU units had established standardized operation procedure (SOP) for CVC placement. 86% of ICU units were capable of ultrasound positioning or guided puncture at the time of catheterization. During catheterization, 88% of ICU units met the sterile dress code. Before and after catheterzation, 81% and 77% of ICU units standardized hand hygiene. Only 31% of ICU units were covered from head to toe by aseptic wipes. For the choice of skin disinfectant, the majority of ICU units (72%) only used iodophor. After tube placement, 54% of ICU units chose sterile transparent dressing and 25% chose sterile gauze dressing. 98% of ICU units were sutured to secure the catheter. Regarding catheter replacement and removal, 45% of ICU units could not be removed or replaced within 2 days in emergency situations where the principle of sterility was not guaranteed. When CLABSI was suspected, 55% of ICU units were able to obtain the catheter tip, transcatheter blood culture, and contralateral peripheral vein blood culture at the same time. For CVC replacement frequency, most ICU units (75%) would not be replaced regularly, and some ICU units would be replaced regularly, but the frequency of replacement was different. For CLABSI prevention and control, 82% of ICU units developed a verification form or supervision form. When analyzing the sources of CLABSI data, most of them were filled in by themselves (60%). As for the frequency of data analysis, 57% were once a month. CONCLUSIONS All ICU units in Shandong Province are standardized in terms of the authorization of operators, the formulation of SOP, the formulation and implementation of verification form and supervision form, ultrasound-guided puncture, and hand hygiene before and after catheterization. However, there are still deficiencies in the training on knowledge and operation of intravascular catheter-associated bloodstream infections, maximum aseptic coverage, catheter replacement and removal, and the reporting sources of CLABSI data, which need to be strengthened in the follow-up work. At present, the selection of CVC, the selection of catheterization site, the selection of skin disinfectant and the selection of dressings after catheterization still need further research.
