Objective:To develop a network-structured clinical pathway grouping rule based on the principles and methods of China healthcare security diagnosis related groups(CHS-DRG), for references for optimizing clinical pathway management.Methods:From August to November 2024, this study constructed a network-structured clinical pathway management framework, followed the grouping principles of CHS-DRG, and developed a network-structured clinical pathway grouping rule through literature analysis and expert discussions. 54 clinical specialists from the sample hospital were organized and grouped according to the rule for the normal magnification cases(139 218 cases) of DRG medical insurance settlement in the hospital in 2023. Using a stratified random sampling method, 205 physicians from 54 clinical specialties in the hospital were selected to quantitatively evaluate the rationality, homogeneity, and clarity of the grouping results. The Likert 5-level scoring method was wsed to assign scores.Results:The network-structured clinical pathway grouping rule and nomenclature was established. A total of 341 main pathways and 35 sub-pathways covering 169 adjacent diagnosis related groups were formed. The quantitative assessment scores for rationality, homogeneity, and clarity were 4.90, 4.87 and 4.87 points, respectively.Conclusions:The network-structured clinical pathway grouping rule based on CHS-DRG had good, feasibility and standardization, and could meet the practical needs of clinical applications.

Objective:This study aims to investigate the differences between two groups of patients treated with nucleos（t）ide analogues（NAs）：those with undetectable HBV DNA by ultrasensitive testing and those with HBV DNA below the quantification limit. The findings will provide a basis for the clinical interpretation and rational use of ultrasensitive HBV DNA results.Methods:This cross-sectional study included patients with chronic HBV infection who were treated with NAs between May 2023 and December 2023 at the outpatient clinic and inpatient department of the Hepatology Department，The Second Hospital of Shandong University. All patients had ultrasensitive HBV DNA results that were either undetectable or less than 20 IU/ml. The group with undetectable ultrasensitive HBV DNA was defined as the target not detected（TND）group，while the group with HBV DNA levels below 20 IU/ml was defined as the limit of quantitation（LOQ）group. Data on patients' sex，age，type of NAs used，routine blood tests，liver and kidney function，quantitative hepatitis B serology，ultrasensitive HBV DNA，HBV pregenomic RNA（pgRNA），abdominal ultrasound，CT or MRI imaging were collected. Differences between the two groups in terms of demographic data and HBV markers were analyzed.Results:A total of 827 patients were included in the study，with 536 patients in the TND group and 291 in the LOQ group. Compared with the TND group，the LOQ group had a younger age（ P<0.001），and higher level of ALT，AST，HBeAg positive rate，HBsAg，and HBV pgRNA（all P<0.001）. Subgroup analyses stratified by HBeAg status，cirrhosis status，and sex showed that the LOQ group had significantly higher levels of HBsAg and HBV pgRNA compared to the TND group in all subgroups（all P<0.05）. Conclusion:The LOQ group had significantly higher levels of HBsAg and HBV pgRNA compared to the TND group.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

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 investigate the predictive value of refeeding syndrome (RFS) and its influencing factors for 30-day intensive care unit (ICU) readmission in critically ill patients.Methods:A prospective cohort study was conducted. Critically ill patients admitted to the department of critical care medicine, department of respiratory and critical care medicine, and department of neurology at Tianjin Medical University General Hospital from January to April in 2025 were enrolled. Patients were assessed for RFS according to the American Society for Parenteral and Enteral Nutrition (ASPEN) criteria. General information within 24 hours of ICU admission was collected via the electronic medical record system. Treatment details and 30-day ICU readmission status were dynamically recorded. Participants were divided into readmission and non-readmission groups based on whether ICU readmission occurred within 30 days. Intergroup comparisons were performed to identify differences. Multivariate Logistic regression was used to analyze the relationship between RFS and its influencing factors with 30-day ICU readmission. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive performance of risk factors.Results:A total of 196 critically ill patients were enrolled, among whom 25 (12.76%) were readmitted to ICU within 30 days and 171 (87.24%) were not. Significant differences were observed in the readmission group compared with the non-readmission group, including significantly higher rates of nasogastric decompression, higher acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, a higher incidence of RFS, and a longer duration of nasogastric decompression. Multivariate Logistic regression analysis showed that RFS was an independent risk factor for 30-day ICU readmission [odds ratio ( OR) = 5.756, 95% confidence interval (95% CI) was 1.603-20.670, P = 0.007]. APACHEⅡ score showed a positive correlation trend with 30-day ICU readmission ( OR = 1.057, 95% CI was 0.991-1.127, P = 0.092). ROC curve analysis showed that the combined prediction model incorporating RFS and APACHEⅡ score had an area under the ROC curve (AUC) of 0.766 (95% CI was 0.668-0.864), with a sensitivity of 88.0% and a specificity of 62.0%, which was significantly superior to a single indicator (the AUC of RFS and APACHEⅡ score was 0.639 and 0.624, respectively). Conclusions:RFS significantly increases the risk of 30-day ICU readmission in critically ill patients. A combined model incorporating RFS and APACHEⅡ score demonstrates good predictive efficacy for 30-day ICU readmission in critically ill patients.

Objective:To explore the real psychological experience of patients with diabetes mellitus combined with end-stage chronic renal failure, and to provide a reference for the development of targeted psychological interventions.Methods:Applying the phenomenological research method, 21 patients with diabetes mellitus combined with end-stage chronic renal failure in the Department of Nephrology of Beijing Friendship Hospital, Capital Medical University from January to July 2024 were selected by purposive sampling, and face-to-face semi-structured in-depth interviews were conducted. For 24 hours after the interviews, two researchers jointly listened carefully to the interview recordings and transcribed them verbatim into textual materials. The interview data were organized and analyzed using the Colaizzi seven-step analysis.Results:A total of three themes and nine sub-themes were extracted, namely, failure of disease self-coping at the early stage of diagnosis (negative psychological distress, burden of disease self-management, difficulty in treatment decision-making) ; insufficient social support (lack of family care, suffering from social alienation, and longing for professional guidance) ; and post-traumatic growth (adapting to the disease, being thankful to others, and looking forward to the future) .Conclusions:Patients with diabetes mellitus combined with end-stage chronic renal failure feel and experience poorly. Healthcare professionals should emphasize the psychological experience of patients during their illness and provide targeted guidance and support to reduce their feeling burden and improve their quality of life.
