    Objective: To analyze the internal composition and changes of the hospitalization costs of lung cancer surgery patients, explore the main influencing factors of hospitalization costs, predict the trend of hospitalization costs, and provide an empirical basis for reducing the hospitalization medical burden of lung cancer patients. Methods: The information on the front pages of the hospitalization medical records of lung cancer surgery patients in a certain third-level Class-A hospital from 2018 to 2022 was collected. The new grey correlation and structural change degree analysis methods were used to study the internal structural changes of hospitalization costs and the correlation degree among them. Through univariate analysis and multiple linear regression analysis, the main influencing factors of hospitalization costs were explored. The GM(1,1) model was used to predict the hospitalization costs from 2023 to 2025. Results: (1) From 2018 to 2022, the average hospitalization cost per case of lung cancer surgery patients in this hospital decreased year by year, with an average annual decrease of 6.67%. (2) Drug costs, diagnostic costs, and surgical treatment costs were the main factors for the structural changes of hospitalization costs, with a cumulative structural change degree of 33.76% and a cumulative contribution rate of 86.23%. (3) The top three in the correlation degree ranking were material costs (0.952), comprehensive medical service costs (0.843), and diagnostic costs (0.697) in turn. (4) Multiple linear regression analysis showed that higher age, more number of complications/accompanying diseases, the medical payment method of urban employee basic medical insurance, and more hospitalization days were the influencing factors for the increase of hospitalization costs of lung cancer surgery patients (P < 0.05); the marital status of being widowed or divorced and emergency admission were the influencing factors for the decrease of hospitalization costs of lung cancer surgery patients (P < 0.05). (5) The GM(1,1) model predicted that the hospitalization costs would further decrease in the next three years. Conclusion: The control of hospitalization costs for lung cancer surgery in this hospital has achieved certain results, especially in controlling drug costs. The costs of surgical treatment that reflect the labor value of medical staff have increased. Diagnostic costs and material costs are the key points for the hospital to further control hospitalization costs in the next step. Clinically, the hospitalization costs of lung cancer surgery patients can be further reduced by early detection, early diagnosis, early treatment, and scientifically reducing the number of hospitalization days. Comprehensive measures should be taken to optimize the composition of patients' hospitalization costs, strengthen the management of controllable factors, and reduce the hospitalization medical burden of lung cancer surgery patients.

    Objective To investigate the factors affecting hospitalization costs of hospitalized patients with chronic obstructive pulmonary disease (COPD), so as to reduce the burden of patients, promote the rational allocation of medical resources, and provide a basis for formulating healthcare policies.Methods The medical record homepage data of chronic obstructive pulmonary hospitalized patients in a tertiary general hospital in Beijing from 2019 to 2022 were selected to study the influencing factors of the hospitalization costs through descriptive analysis, rank sum test, correlation analysis, and multifactor regression analysis.Results Male patients (66.0%) outnumbered female patients (34.0%) among 1 053 COPD patients, the proportion of patients aged 60-89 years old was the highest (82.8%), the number of medicare-paid patients was the highest (88.2%), emergency admissions (57.1%) were higher than outpatient admissions (42.9%), and the percentage of hospitalization days with 10-19 days was the the most (45.3%). The high incidence seasons of chronic obstructive pulmonary disease were fall and winter (51.9%), and common comorbidities were coronary heart disease (78.3%), hypertension (73.0%), and pulmonary heart disease (48.5%). Chinese and Western medicine (36.75%), medical services (29.57%), and diagnosis (22.82%) accounted for the largest share of hospitalization costs. There was a statistical difference in hospitalization costs for variables of age, medical payment method, number of hospitalization days, comorbidities of hypertension, coronary heart disease, respiratory failure, pulmonary heart disease, treatment with antimicrobials, and ventilator-assisted therapy (P<0.05) . Regression analysis showed that the older the age, the longer the hospitalization days, the higher the number of comorbidities, the more use of antimicrobial drugs and ventilator therapy, the higher the hospitalization costs. Compared to medical insurance patients, public medical care was positively correlated with hospitalization costs (P<0.05).Conclusion Health education should be strengthened, early screening and intervention for elderly patients and COPD patients with a history of cardiovascular disease should be carried out, and multidisciplinary diagnostic and treatment modes and improved clinical pathways should be utilized to standardize the diagnostic and treatment processes, logically shorten the average number of hospitalization days, reduce the waste of medical resources and alleviate the patients′ economic burden.

    The introduction of DIP (Diagnosis-Intervention Packet, paying by disease scores) and DRG (Diagnosis-Related Groups, paying by disease diagnosis related groups) payment models marks the transformation of China's medical insurance payment method from the traditional "post-payment" to the "pre-payment" model, which puts forward higher requirements for the financial management and budget management of public hospitals. This paper analyzes the impacts of DIP/DRG payment reform on aspects such as hospital financial management, medical record management, cost accounting and information systems, and points out that it promotes a systematic change in the hospital management model. Secondly, based on the process management theory, it explores the construction path of the comprehensive budget management system in public hospitals, mainly including the improvement of budget management systems, the clarification of budget objectives, the optimization of budget management processes, and the establishment of budget supervision and evaluation mechanisms. Through investigations and combing relevant literature, this paper proposes optimization strategies for the budget management system in view of the characteristics of DIP/DRG payment reform. The aim is to enhance the operational performance and financial management level of public hospitals under the new payment model and promote the high-quality development of hospitals.

    Objective To assess the causal effect of schizophrenia on substance abuse and alcohol use disorder, to clarify the causal associations between diseases and behaviors, and to provide new ideas and protocols for improving clinical treatment and prognosis.
    Methods Summary statistics from genome - wide association studies of schizophrenia, substance abuse, and alcohol
    use disorder were used to exclude instrumental variables with confounding factors and directionally harmonize the data, provided that the three major assumptions of Mendelian randomization of instrumental variables were met. Two - sample Mendelian randomization of the data was performed using the inverse variance weighted method as the main analytical method, with the weighted median method, MR Egger method, simple mode and weighted mode as supplementary analytical methods. Sensitivity analyses were performed using Cochran Q test, MR - Egger intercept analysis and leave - one - out method to test for heterogeneity and pleiotropy and to assess the stability and reliability of the results.
    Results In order to exclude the effect of weak instrumental variables and to make instrumental variables strongly correlated with exposure, a more stringent threshold than that of previous studies was used, and a total of 64 single nucleotide polymorphism loci were included as instrumental variables with the P - value threshold set at 5×10⁻¹⁰. The inverse variance weighted method estimated that the risk (OR) of developing substance abuse in schizophrenia was 1.19 times higher than that of the general population (95% CI: 1.126 - 1.261, P = 1.499×10⁻⁹), and the results of the other four analyses also indicated that schizophrenia increased the risk of substance abuse. For the data on
    schizophrenia and two groups of alcohol use disorder, the inverse variance weighted method estimated that the risk (OR) of alcohol use disorder in patients with schizophrenia was 1.17 times (95% CI: 1.105 - 1.239, P = 7.398×10⁻⁸) and 1.13 times (95% CI:1.072 - 1.187, P = 3.124×10⁻⁶) that of the general population, respectively. The evaluation results of the weighted median method, simple mode and weighted mode also provided evidence that schizophrenia increased the risk of alcohol use disorder.
    Conclusion The existence of a positive causal effect of schizophrenia with substance abuse and alcohol use disorders provides an important idea and basis for subsequent clinical research.

    Objective To analyze the impact of age and surgical procedures on hospitalization costs for lung cancer patients undergoing surgery.Methods The study focused on surgical patients who were primarily diagnosed with lung cancer (C34.) in a tertiary hospital in Ningbo from January 1, 2022 to December 31, 2022, and analyzed their DRG enrollment status. Differential analysis of patient costs in the DRG group using t-test and analysis of variance based on age and surgical procedures.Results A total of 2 489 lung cancer surgery patients were all assigned to the EB1 chest surgery group. There was no statistically significant difference (P>0.05) in the impact of age and surgical procedures on patient costs between EB11 major chest surgery with severe complications and comorbidities. The hospitalization costs of patients over 60 years old in the group of EB13 major chest surgery with general complications and comorbidities and in the group of EB15 major chest surgery without complications and comorbidities were significantly higher than those of patients under 60 years old (P<0.05). As age increased, hospitalization costs increased, and the amount of medical insurance losses in hospitals increased, with statistical significance (P<0.05). Except for no difference in hospitalization costs between lobectomy and total pneumonectomy, there was a statistically significant difference in hospitalization costs among other surgical procedures in the EB13 group (P<0.05). Except for no difference in hospitalization costs between partial lobectomy, lobectomy and pneumonectomy, all other surgical procedures showed statistically significant differences (P<0.05) in the EB15 group. As the surgical resection range increased, hospitalization costs increased, the medical insurance losses increased in the hospital, and the difference was statistically significant (P<0.05).Conclusion The hospitalization costs of lung cancer patients undergoing surgery are greatly influenced by age and surgical procedures. When optimizing the DRG grouping scheme, it is necessary to improve the compatibility with clinical practice and further refine it with full consideration of the actual clinical situation.

    Objective To explore the latent profile category of team Cha-xu among clinical nurses and its influence on job withdrawal behavior, and provide some reference for the management of clinical nurses.Methods Clinical nurses were selected from two tertiary hospitals in Wenzhou, Zhejiang Province from January to April 2023 by convenience sampling. The basic data questionnaire, perceived climate of team Cha-xu scale and job withdrawal behavior scale were used in the investigation.Results A total of 392 clinical nurses were included in the study. The score of perceived climate of team Cha-xu in clinical nurses was 41.15±8.07. The model fitting effect of three latent profile categories was best, namely "insider" with low scores, accounting for 28.06%; "intermediate", accounting for 41.07% and "outsider" with higher scores, accounting for 30.87%. Nurses with different professional titles, work relationship and monthly income showed significant differences in perceived climate of team Cha-xu (P<0.05). The score of job withdrawal behavior was 18.13±3.39. The nurses in different perceived climate of team Cha-xu category had different job withdrawal behaviors (F=4.883, P<0.05). The pairwise comparison results showed that there was no significant difference between "insider" and "middleman" (P>0.05), while there was significant difference between "outsider" and "insider", "outsider" and "middleman" (P<0.05).Conclusion Nursing managers should pay attention to the impact of perceived climate of team Cha-xu on job withdrawal behaviors, strive to improve their own management level, create a harmonious working atmosphere, and give clinical nurses full support and care, so as to reduce the perceived climate of team Cha-xu and the job withdrawal behavior.

    Objective To investigate and analyze the status of medication near-miss reporting barriers of nurses, and analyze its influencing factors.Methods In October, 2023, 285 clinical nurses were investigated and analyzed by stratified cluster sampling method with the general situation questionnaire, the reporting disorder scale of nurses′ drug approach error and the scale of nurses′ organizational climate perception.Results The total mean score of nurse medication near-miss reporting barriers was (3.80±0.51) (The average score of the scale is 1 to 6 points, the higher the score indicates the more serious the reporting disorder), and the total mean score of nurses′ organizational climate perception was (3.16±0.45) (The scale is divided into 1 to 4 points, the higher the score, the better the organizational atmosphere perceived by nurses). There were statistically significant differences in the total average score of nurses′ medication near-miss reporting barriers in terms of working years, professional title and position (P<0.05). Correlation analysis showed that there was a negative correlation between the nurses′ medication near-miss reporting barriers and the total score of organizational climate perception of nurses and its various dimensions (r=-0.558,P<0.01). Multiple linear regression analysis showed that working years, job title, position, nurses′ organizational climate perception were the main influencing factors of nurses′ medication access error reporting disorder.Conclusion The medication near-miss reporting barriers and the organizational climate perception of nurses are above medium level. The medication near-miss reporting barriers of nurses are affected by working years, professional title, position, and organizational atmosphere, so good organizational atmosphere of the department can reduce the reporting barriers of near-miss in drug administration by nurses.

    Objective To analyze the main disease composition of inpatient deaths in a tertiary comprehensive hospital
    from 2016 to 2022, and provide a basis for the hospital to further reduce case fatality rates. Methods Medical record data suchas name, gender, age, discharge diagnosis, disease code, etc. were extracted from the electronic medical record system of a tertiary comprehensive hospital from January 1, 2016 to December 31, 2022. According to the International Classification of Diseases (ICD - 10), Excel 2016 and SPSS 25.0 were used to perform statistical analysis on the data. Results From 2016 to 2022,the number of deaths was 3777, with the case fatality rate of 1.14%. Among them, the case fatality rate of male (1.60%) was higher than that of female (0.73%), and the difference was statistically significant (χ² = 564.778, P < 0.001). With the increase of age, the case fatality rate gradually increased, with the highest case fatality rate 5.09% for those aged 90 and above,and the highest number of deaths occurring in the 70 - 79 age group. The top three causes of death were tumors, circulatory system diseases, and respiratory diseases. Conclusion It is necessary to pay attention to the health status of male and elderly groups,and strengthen the promotion of health knowledge. Tumors, circulatory system diseases, and respiratory system diseases are the
    main causes of death. It is necessary to strengthen talent development and technological innovation in corresponding departments to reduce case fatality rates.

    Objective To explore the risk factors of unplanned re-intubation in patients with acute respiratory failure treated with nasal high-flow oxygen therapy (HFNC), and to construct a risk prediction model based on independent risk factors to analyze the predictive value of these risk factors. Methods A total of 198 patients with acute respiratory failure who were hospitalized in our hospital and received HFNC treatment from September 2020 to August 2023 were retrospectively selected. According to whether there was unplanned re-intubation, the patients were divided into the re-intubation group (n = 37) and the non-re-intubation group (n = 161). Univariate analysis and multivariate logistic regression analysis were used to obtain independent risk factors. A risk prediction model was constructed based on the regression analysis method, and the predictive efficiency of the model was tested by the receiver operating characteristic curve and the calibration curve. In addition, 85 patients who were treated from September 2023 to June 2024 were selected as the validation set. The ROC curve and calibration curve were drawn using the data of the validation set to externally verify the predictive efficiency of the model. Results The results showed that age, smoking history, Acute Physiology and Chronic Health Evaluation II score (APACHE II score), duration of invasive mechanical ventilation, residual volume of secretions, high oxygen flow rate setting, and comorbid chronic lung disease were independent risk factors for unplanned re-intubation in patients with acute respiratory failure treated with HFNC (P < 0.05). The area under the curve of the constructed risk prediction model was 0.878, indicating good discrimination ability of the model. The mean absolute error of the calibration curve was 0.015, and the calibration curve was close to the ideal curve, suggesting that the model had good calibration performance and was reliable and stable. The results of the ROC curve and calibration curve of the validation set were good, indicating that the model had good external predictive efficiency. Conclusion The occurrence of unplanned re-intubation in patients with acute respiratory failure treated with HFNC is affected by risk factors such as age, smoking history, and APACHE II score. The risk prediction model constructed based on each independent risk factor has good predictive performance, which can provide a basis for preventing unplanned re-intubation clinically and rationally allocating medical resources.

    Objective To explore the relationship between respectful leadership, psychological security and employee satisfaction, in order to provide reference for hospital managers to improve employee satisfaction.Methods Respectful leadership scale, psychological safety scale and job satisfaction scale were used to conduct a questionnaire survey on employees for descriptive analysis, correlation analysis and a structural equation model was constructed based on the results.Results The total score of respectful leadership was (45.82±10.25), psychological safety was (17.31±3.43) and employee satisfaction was (26.90±5.88). Pearson correlation analysis showed that there was a significant positive correlation between the three variables, and the absolute value of correlation coefficient ranged from 0.335 to 0.583 (P<0.01). Respectful leadership had no direct predictive effect on employee satisfaction (β=0.05, P>0.05), the indirect effect coefficient of respectful leadership on employee satisfaction was 0.35, the total effect coefficient was 0.40, and the mediating effect accounted for 87.5%. This indicates that respectful leadership indirectly affects employee satisfaction through psychological safety.Conclusion Psychological safety plays an mediating role in the relationship between respectful leadership and employee satisfaction. The management departments can evaluate the performance of respect for subordinates by leaders, advocate respectful leadership, and improve the psychological security and satisfaction of employees.

    Objective: To analyze the current situation of the spatial layout of medical services in secondary and tertiary hospitals in Yantai City, and provide a reference for the further construction and planning of medical resources and the improvement of the accessibility of medical services for residents. Methods: Taking the secondary and tertiary hospitals in Yantai City as the center, the actual coverage of medical services was calculated according to the GIS network analysis model, Thiessen polygons and other methods. Results: On average, each tertiary hospital in Yantai City serves 30.15 residential areas, with an average shortest distance to seek medical treatment of 10.19 km, and 80.36% of the residential areas can be covered within 15 minutes. Each secondary hospital serves an average of 15.87 residential areas, with an average shortest distance to seek medical treatment of 4.28 km. The areas within 30 minutes can basically connect the junctions of various districts and counties, and the service range within 60 minutes covers the whole city. Conclusion: The relevant departments should attach importance to the weak areas in the spatial layout of medical services in secondary and tertiary hospitals, improve the current situation of the fragmented distribution of the service areas of tertiary hospitals, promote the rational distribution of medical resources, and form a new pattern of spatial development.

    Objective To classify hospitalized patients' diseases based on cost structure, and to provide data reference for controlling medical costs and optimizing the structure of medical income. Methods The first page information of inpatient cases from January 2023 to June 2024 in a tertiary hospital in Beijing was selected to extract inpatient expense details, and patients were categorized based on the ICD - 10 disease diagnosis codes of their primary discharge diagnoses. K - means clustering analysis was used to classify diseases according to cost structure, so as to analyze the characteristics of each category's cost structure. Results Based on cost structure, patient diseases were classified into four categories. Category 1 included diseases with high consumable costs, mainly comprising pyonephrosis, ureteral stones, and unstable angina pectoris; category 2 had the highest diagnostic fees, including unspecified liver cirrhosis, alcoholic liver cirrhosis, chronic hepatitis B without delta agent, etc.; category 3 featured balanced proportions across all fee types, including installation and adjustment of urinary devices, unspecified liver
    malignancies, medical abortion without complications, etc.; category 4 had relatively higher medication costs, including other specified medical care, chronic liver failure, and chemotherapy sessions for tumors, among others.Conclusion Although high consumable or medication costs may be due to treatment requirements of certain diseases, it is still necessary to reduce expenses through multiple links such as procurement, usage, and management to effectively control medical costs and improve the quality of medical services.

    Objective To construct a prediction model for dysphagia in elderly patients with chronic obstructive pulmonary disease (COPD) based on the BP neural network method. Methods A retrospective analysis was conducted on 313 COPD patients who were treated in the Second People's Hospital of Pingxiang City from June 2021 to June 2024, among whom 58 had dysphagia. SPSS was used for propensity score matching, with gender, the same age (±3 years), and the same Modified Barthel Index (MBI) (±1 point) as the matching factors. Among them, 13 patients with dysphagia did not find matching objects, and the clinical data of 40 patients without dysphagia were missing. Finally, 45 patients were included in the dysphagia group and 155 patients were included in the non-dysphagia group. Questionnaires and surveys were used to collect the general information of the patients. Univariate and logistic regression analyses were used to analyze the significant influencing factors, and a prediction model for dysphagia in COPD patients was constructed based on the BP neural network method.Results The results of logistic regression analysis showed that smoking history, nutritional status, number of missing teeth, whether to concentrate on eating, eating posture, partial pressure of carbon dioxide, types of medications, degree of dyspnea, and severity of the disease were influencing factors of dysphagia in COPD patients (all P < 0.05). When constructing the BP neural network, the prediction accuracy of the modeling set was 88.10%, and the prediction accuracy of the validation set was 89.40%. The area under the curve (AUC) of the model was 0.926 (95% CI: 0.892-0.966), the sensitivity was 80.00%, the specificity was 90.30%, and the Youden index was 0.703. Among them, the degree of dyspnea (100.00%), the severity of the disease (91.80%), and the number of missing teeth (74.60%) were the top three influencing factors in terms of the importance ranking of independent variables. Conclusion The prediction model for dysphagia in elderly COPD patients constructed based on the BP neural network method has good fitting performance and can provide a reference for relevant clinical studies.

    Objective To explore the influencing factors of incision infection after open reduction and internal fixation (ORIF) of tibial fractures, develop an individualized nomogram prediction model and verify it. Methods The clinical data of 180 patients with tibial plateau fractures who received ORIF treatment in our hospital from February 2021 to September 2022 were retrospectively analyzed, and the occurrence of postoperative incision infection in these patients was analyzed. The potential warning indicators of incision infection after ORIF of tibial fractures were preliminarily screened by lasso regression; the influencing factors of postoperative incision infection were analyzed by multivariate binary logistic regression; an individualized nomogram prediction model was constructed; the goodness of fit, calibration degree and clinical applicability of the individualized nomogram prediction model were evaluated by Hosmer-Lemeshow test, calibration curve and decision curve; and the receiver operating characteristic (ROC) curve of the model was drawn. In addition, 180 patients with tibial plateau fractures who received ORIF treatment in our hospital from October 2022 to May 2024 were selected for external verification. Results Among 180 patients with tibial plateau fractures who received ORIF treatment, 38 cases had incision infection, with an incidence rate of 21.11%, including 14 cases (7.78%) of deep infection and 24 cases (13.33%) of superficial infection. Compared with the non-infected group, the infected group had a higher body mass index (BMI), a longer operation time, and a higher proportion of smoking, diabetes mellitus, open injury, and American Society of Anesthesiologists (ASA) grade III-IV (P < 0.05). BMI, smoking, diabetes mellitus, open injury, ASA grade, and operation time were potential warning indicators of incision infection after ORIF of tibial plateau fractures. BMI, smoking, diabetes mellitus, open injury, ASA grade, and operation time were influencing factors of incision infection after ORIF of tibial plateau fractures. The Hosmer-Lemeshow test (χ² = 3.998, P = 0.857) suggested that the individualized nomogram prediction model had a high goodness of fit. The calibration and decision curves indicated a high calibration degree and good clinical net benefit. The ROC curve showed that the area under the curve (AUC) was 0.918, the 95% confidence interval (CI) was 0.868-0.954, the sensitivity was 81.58%, and the specificity was 88.73%, suggesting that the individualized nomogram model had a high predictive efficiency. External verification showed that the prediction model established based on the data of the modeling group had good discrimination and consistency. Conclusion The individualized nomogram prediction model constructed in this study based on BMI, smoking, diabetes mellitus, open injury, ASA grade, and operation time can effectively predict the occurrence of incision infection after ORIF of tibial plateau fractures, which is helpful to reduce the occurrence of postoperative incision infection and promote the rapid recovery and good prognosis of patients.

    Objective To analyze the internal composition and correlation of hospitalization expenses of negative difference cases in gynecological DRG disease group, so as to provide decision - making reference for hospitals to optimize the cost structure and realize the fine management. Methods The medical insurance year - end liquidation data of the DRG group (a total of 13 groups) with more than 100 cases of gynecological diseases in a tertiary hospital in 2023 were collected. The structural change degree method was used to analyze the changes in the internal composition of hospitalization expenses, and the new grey correlation analysis was used to evaluate the correlation between each subdivision cost and the total hospitalization cost.Results The proportion of negative balance in 8951 cases was 50.2%. There were 8 groups with more than 50% negative difference cases in each DRG group. The three groups with the highest degree of structural change were NZ13 (other diseases of female reproductive system with general complications and comorbidities), NB13 (female reproductive system reconstruction surgery with general complications and comorbidities), and RE13 (malignant proliferative diseases chemical and/or targeted, biological treatment with general complications and comorbidities). The contribution rate of inspection fee was higher in each group, followed by

    operation fee. The top three of the correlation degree of the subdivision cost and the average cost with hospitalization expenses were operation cost (0.744), inspection cost (0.743) and drug cost (0.712). Conclusion It is necessary to pay attention to the fees of surgical items, carry out reasonable inspections, scientifically control the proportion of drug consumption and rationally adjust the cost structure, standardize the quality of the medical record home page,optimize the clinical pathway, and reduce the occurrence of negative difference cases through various measures.

    Objective To analyze and summarize the research literature on the integration of medical care and elderly care in China, and provide theoretical support for the healthy and orderly development of the integration of medical care and elderly care in China. Methods Taking the literature from domestic core journals included in CNKI, Wanfang, and VIP databases as the data source, CiteSpace and Excel software were used to analyze the number of published papers, authors, research institutions, and keywords of the research on the integration of medical care and elderly care in China from 2014 to 2024. Results The overall number of published papers on the integration of medical care and elderly care in China showed a trend of first increasing and then decreasing; the teams engaged in the research on the integration of medical care and elderly care were concentrated in various universities and scientific research institutes, and many productive authors emerged; in terms of regional distribution, they were mostly concentrated in economically developed regions such as Beijing, Shanghai, Nanjing, Zhejiang, and Wuhan; however, there was a lack of cooperation among institutions and authors, and no authoritative research institutions and authors had been formed yet; the research in the field of the integration of medical care and elderly care in China involved many aspects such as the service subjects, service contents, service objects, and service models of the integration of medical care and elderly care; the analysis combining keyword clustering and burst keywords showed that the field of the integration of medical care and elderly care in China was roughly divided into three stages: the main research stage (2014-2017), the reflection stage (2018-2020), and the deepening stage (2021-2024). Conclusion Certain achievements have been made in the research field of the integration of medical care and elderly care in China, and the academic community has conducted in-depth research on various aspects of this field.

    Objective To linearly weight the results of inverse distance weighted interpolation (IDW), ordinary Kriging interpolation (OK) and thin plate spline interpolation (TPS), and fit a comprehensive model of ensemble interpolation to objectively and comprehensively reveal the spatial pattern of diseases. Methods Taking the mortality rate of liver cancer at county level in Guangxi for example, we revealed the death risk via IDW, OK and TPS interpolation models, and compared the mean prediction error (MPE), root - mean - square prediction error (RMSE), R - square (R2) value and the fitting smoothness of spatial interpolation maps between the IDW model, the OK model and the TPS model. Then, we used the RMSE of above specific models to generate weights to linearly weight single interpolation models, and estimated the death risk of liver cancer across Guangxi by a comprehensive model of ensemble interpolation.
    Results The fitting indicators of IDW, OK and TPS models were somewhat inconsistent, and each model had its advantages and disadvantages. Specifically, from small to large, the MPE was TPS (0.002), OK (0.004) and IDW (0.020), respectively, and the accuracy of TPS was better than that of OK. From small to large, RMSE was OK (0.349), TPS (0.362) and IDW (0.390), respectively, and the variability of OK was better than that of TPS. From small to large, R2 was OK (0.47), TPS (0.44) and IDW (0.37), respectively, and OK was better than TPS in fitting accuracy. The comprehensive model of ensemble interpolation integrated the advantages of above three models and overcame the instability of specific models, with MPE, RMSE and R2 being 0.005, 0.352 and 0.43, respectively. Conclusion IDW, OK and TPS interpolation models have their own advantages in estimating the spatial patterns of diseases, but findings of different models are inconsistent to some extent. The comprehensive model of ensemble interpolation reduces the uncertainty of each single model, balances the advantages and disadvantages of each single model and generated a comprehensive evidence to reveal the spatial pattern of diseases, via weighting above three single models.

    Objective To construct a medical mental damage compensation model based on Ordinary Least Squares (OLS) regression, so as to analyze the influencing factors of mental damage compensation in medical damage liability dispute cases. Methods Taking 830 medical damage dispute cases as the research objects, relevant factors were included in the OLS regression analysis through analysis of variance, and a linear regression model was constructed. Results The medical mental damage compensation model showed that the western and northeastern regions in the factor of "region" were negatively correlated with mental damage compensation (P < 0.05), while hospital liability, claimed compensation amount, and disability grade were positively correlated with mental damage compensation (P < 0.05). Conclusion The medical mental damage compensation model is simple with simplified indicators, which is convenient for judges to refer to the data. It is helpful for the pre-litigation settlement of medical disputes and further plays the role of people's mediation in doctor-patient disputes.

    Objective The study aimed to sort out the research hotspots and development trend in this field in the past 10 years, and to provide reference for the research of cancer prognosis prediction model, through the econometric statistics and
    visual analysis of the related research of cancer prognosis prediction model. Methods Web of Science, PubMed, and CNKI databases were used as the search sources, and the literature on cancer prognosis prediction model published in the Chinese and English search sources from Jan. 1st, 2013 to June 15th, 2024 was analyzed and visualized based on CiteSpace, VOSviewer software, and the bibliometrix package of the R language.Results A total of 1341 Chinese articles were retrieved through the CNKI database, with 1322 valid articles remaining after duplication. From the WOS and PubMed databases, 2069 and 3284 English articles were retrieved, respectively. After merging and duplication, 4908 valid English articles were retained. The overall trend of publications from 2013 to 2024 was upward. The country with the most publications in English literature was China (2270 articles), the institution with the most publications was Fudan University (268 articles), and the institution with the most publications in Chinese literature had only five articles. The authors who have published the most Chinese literatures were Wang Debin (5 articles), Chai Jing (5 articles), and Liu Yang (5 articles), and the author who published the most English literature was Wang Wei (24 articles). The high - strength emerging words in both Chinese and English literature were breast cancer (Chineseemergent strength: 8.95, English emergent strength: 11.06), and the clustering results showed that the related studies of colorectal cancer, bladder cancer, prostate cancer, machine learning were more prominent. Conclusion Cancer prognostic prediction modeling is receiving more and more attention from experts and scholars, covering more cancer types and richer research methods. Machine learning algorithms are being used more often, and the nomogram visualizes the results to better guide clinical practice. The application of genome - wide association analysis in the field of cancer prognosis prediction is expected to be a potentially promising research direction. Universal collaboration among countries, institutions, and authors has not yet been established, and there is a need to further strengthen the cooperation for deeper academic cross - fertilization. The cancer - suppressive mechanisms of
    iron death and copper death have received more attention and have a broad clinical research prospect.

    Objective To understand the hospitalization situation of diabetic patients in Tianjin and the changing trends of the composition of their hospitalization expenses before and after the implementation of the DRG payment reform policy, and to analyze the effectiveness of the DRG policy reform and the possible existing problems. Methods Based on the medical insurance settlement data in Tianjin before and after the implementation of DRG from 2021 to 2023, the degree of structure variation (DSV), grey correlation analysis (GRA) and interrupted time series (ITS) analysis were used to study the impact of the DRG policy on the hospitalization situation and expenses of diabetic patients. Results Compared with before the reform, the emergency admission rate of hospitalized diabetic patients increased after the reform ($P < 0.001$), while the length of hospital stay, hospitalization expenses, comprehensive medical service fees, drug fees, health material fees and individual out-of-pocket expenses all decreased ($P < 0.001$). The results of DSV and GRA analysis showed that the main factors affecting the hospitalization expenses of diabetic patients were examination fees, laboratory test fees, comprehensive medical service fees and drug fees. The results of ITS analysis showed that after the DRG reform, the average inpatient expense per visit decreased by 281.50 yuan ($P < 0.001$), and the monthly growth rate reversed from 56.15 yuan before the reform to -42.51 yuan ($P < 0.001$), and the reduction rate of individual out-of-pocket expenses increased ($P < 0.001$). Except for the examination fees, the growth trends of the composition of various hospitalization expenses all reversed ($P < 0.001$). Among them, the comprehensive medical service fees had the largest reduction, and the monthly growth rate reversed from 21.68 yuan before the reform to -17.23 yuan ($P < 0.001$), followed by drug fees, laboratory test fees and health material fees. Conclusion The DRG payment method reform in Tianjin has achieved remarkable results, with obvious achievements in reducing costs and increasing efficiency, effectively reducing the economic burden on patients. However, the increase in the emergency admission rate and the still unreasonable expense structure suggest that the DRG reform still needs further optimization.

    Objective  To systematically evaluate the effect of dapagliflozin on glucose and lipid metabolism in patients with stage Ⅲ of diabetic nephropathy (DN-Ⅲ). Methods  Randomized controlled studies (RCTs) on the effect of dapagliflozin on glucose and lipid metabolism in patients with DN-Ⅲ were retrieved. Literature was screened, the data were extracted, and RevMan 5.4.1. was used for quality evaluation. Results  A total of 2107 patients were included in 23 studies. Meta results showed that compared with the control group, dapagliflozin significantly reduced HbA1c, FBG, PBG, HOME-IR and significantly increased HOME-β in patients with DN-Ⅲ, but it had little impact on ΔFIns; compared with the control group, dapagliflozin significantly reduced TC, TG, LDL-c and significantly increased HDL-c in patients with DN-Ⅲ; compared with the control group, dapagliflozin significantly reduced SBP and DBP in patients with DN-Ⅲ. In addition, compared with the control group, dapagliflozin could significantly reduce BMI, but there was no significant difference in the incidence of ADR. Conclusion  Dapagliflozin can improve the glucose and lipid metabolism in patients with DN-Ⅲ, and it is safe and effective. However, in view of the limitations of the inclusion study, it still needs to be verified by a well-designed large-scale clinical randomized controlled study.

    Objective  To analyze the changes in the structure of outpatient and inpatient costs in a public hospital in Binzhou under the background of new medical reform, and provide references and theoretical basis for further implementing healthcare reform policies in Binzhou. Methods  Outpatient and inpatient cost data from a public hospital in Binzhou City from 2013 to 2022 were collected, and grey correlation method and structural change degree were used to analyze the indicators. Results  Grey relational analysis revealed that, from 2013 to 2022, the top three correlated factors in outpatient expenses were medication expenses, examination fees, and laboratory fees; in inpatient expenses, medication expenses, health material fees, and examination fees were the top three expenses. The results of the structural correlation analysis showed that in both outpatient and inpatient expenses, the change in medication expenses was the largest contributor with a negative change. Conclusion  Under the background of the new medical reform, there have been initial achievements in controlling medication expenses. However, examination fees and health material fees have shown an upward trend and accounted for a relatively high proportion, which requires attention. Technical service fees have been increasing annually but still have a relatively low proportion.

    Objective To explore the reasons for the behavior of uploading minor diagnostics with no resource consumption, analyze the impact of this behavior on medical insurance payment, improve the awareness and attention of medical institutions to this problem, and seek targeted solutions from two aspects of hospital management and medical insurance supervision.Methods By comparing medical record filling information and DRG enrollment results, quality control was carried out on randomly selected medical insurance settlement lists, and theoretical research was carried out on cases that received more medical insurance payments. The process of the behavior of uploading minor diagnostics with no resource consumption was sorted out to analyze the deep causes. Results The behavior of uploading minor diagnostics with no resource consumption is prominent, and the high - score group leads to high medical insurance payment. This problem is even more pronounced in comprehensive medical institutions, but existing regulatory instruments are not working well.

    Objective To explore the problems and countermeasures of medical staff in public hospitals in dealing with public health emergencies, in order to provide valuable reference for improving the emergency response capacity of public hospitals. Methods A stratified sampling method was used to randomly select 593 medical staff from 33 wards of 7 departments in a public Grade Three general hospital in Shandong Province, which were closely related to public health. In order to improve comparability and assess the overall performance level more accurately, this study converted scores into grades, so as to analyze the current situation and influencing factors of public hospital medical staff in responding to public health emergencies, and put forward improvement measures and suggestio.Results The participation rate of medical staff in emergency drills, emergency training and emergency handling in response to public health emergencies was 45.14%, and the qualified rate was 58.40%, both at a low level. The qualified rate of medical staff who did not participate in such activities was only 40.78%, compared with 79.83% who participated in activities, the difference was statistically significant (P < 0.05). The overall score rate of these three aspects was 56.11%, indicating that the level of emergency ability was low, and the average score was (2.81 ± 0.88), which
    was significantly lower than the qualified score (P < 0.001). Among the three dimensions, the score rate of emergency rescue ability was the highest (75.34%), followed by personal emergency attitude (73.52%), and the ability to master emergency knowledge was the lowest (65.23%). Conclusion In response to public health emergencies, medical staff in the public hospital need to improve their participation in emergency practice activities, ability to grasp emergency knowledge, personal monitoring and early warning ability, and mental health. It is suggested to strengthen the training of basic emergency knowledge and practical skills of medical staff, improve the monitoring and early warning system, and improve the psychological intervention ability of medical staff.

    Objective To retrospectively analyze the inpatient death cases in a tertiary general hospital, so as to understand and master the death situation and causes of inpatients in the hospital in recent years, and provide a scientific and reasonable management basis for the hospital. Methods The inpatient death cases in a tertiary general hospital from 2021 to 2023 were collected and retrospectively analyzed from the aspects of age, gender, department, and disease diagnosis at death. Results There were 819 death cases in this hospital from 2021 to 2023, with a total inpatient mortality rate of 0.58%. The male-female ratio was 1.96:1, and those aged 60 and above accounted for 82.42%. The departments with the most deaths were mainly ICU, Department of Cardiology, Department of Respiratory Medicine, and Department of Neurosurgery. The top three diseases were tumors, circulatory system diseases, and respiratory system diseases. Conclusion With the aggravation of population aging, tumors, circulatory system diseases, and respiratory system diseases have become the main causes of inpatient death in this hospital, and elderly patients are the key objects that need attention.

    Objective To explore the correlation between professional self - concept and personal career planning of undergraduate nursing students. Methods Convenience sampling method was used to select 191 nursing undergraduate students from a nursing college in Shandong Province as the survey subjects. The questionnaire survey was conducted by using a general information questionnaire, a professional self - concept scale, and a personal career planning scale. Results The average score of the professional self - concept scale items for undergraduate nursing students was (2.99 ± 0.37), which was above the average; the average score of the items in the personal career planning scale was (3.56 ± 0.54), which was at a moderate level; there was a positive correlation between the two groups (the typical correlation coefficients were 0.661 and 0.412, respectively); and professional self - concept, learning status, and relationships with classmates were the main influencing factors of personal career planning (P < 0.05), jointly explaining 44.2% of the total variation in personal career planning for undergraduate nursing students.
    Conclusion The personal career planning of undergraduate nursing students is above the medium level. Education managers and nursing students themselves should attach importance to the cultivation of professional self - concept to improve their personal career planning level.
