Wu Jingyi，Deng Wei， Yu Yongfu
DOI: 10.3969/j.issn.1006-5253.2023.03.002
Guide::
Objective
To explore the association of cognition impairment with education status and mortality among the Chinese elderly and to provide recommendations for cognitive management of the Chinese elderly.
Methods
The study population was from the elderly aged 65 and above in the Chinese longitudinal healthy longevity survey (CLHLS) in 2005 and 2008. The traditional Cox proportional hazard model and additive Cox proportional hazard model were used to estimate the associations of cognitive impairment with education status and all-cause mortality. Data analysis included univariable analysis, stratified analysis and interaction analysis. The additive Cox proportional hazard model results were presented in the form of images.
Results
Among 15 860 eligible participants included in the study, 11 044 died during follow-up. The results showed that cognitive impairment would increase the mortality risk of the elderly (HR=1.32, 95%CI:1.26-1.39). And after stratified by education status, the hazardous effects diminished as education status decreased (years of schooling >6 years HR=1.47, 95%CI: 1.08-2.00; years of schooling 1-6 years HR=1.44, 95%CI: 1.26-1.63; years of schooling 0 year HR=1.32, 95%CI:1.25-1.39). In addition, the association of education status and mortality was inconsistent across cognitively diverse populations. The protective effect of education status on mortality was observed among the people with normal cognitive function (HR=0.83, 95%CI: 0.77-0.91) but not observed among the people with cognitive impairment (HR=1.09, 95%CI: 0.81-1.47).
Conclusion
It is suggested that the community health centers should manage the cognitive function of the elderly according to their education status.

Zhang Qiping， Ji Conghua，Lu Jinqi， Wang Xiaoteng
DOI: 10.3969/j.issn.1006-5253.2023.03.003
Guide::
Objective
To explore the application value of autoregressive integrated moving average (ARIMA) multiplicative seasonal model in predicting the epidemic trend of carbapenem resistant Klebsiella pneumoniae (CRKP), and to provide a theoretical basis for grasping the epidemic trend and formulating prevention and control measures of CRKP infection in hospitals.
Methods
Based on the monthly number of CRKP detected in a tertiary hospital in Jiaxing City from 2016 to 2021, the ARIMA multiplicative seasonal model was constructed with SPSS 26.0 software. The actual number of CRKP plants detected in 2022 was selected as the validation data set and compared with the predicted value, so as to evaluate the prediction efficiency of the model.
Results
The total number of CRKP detected in hospital showed a downward trend year by year from 2016 to 2021. The incidence was concentrated from July to September, and the peak was in September, which was seasonal and periodic. The Bayesian information criterion (BIC) of the fitted ARIMA (0, 1, 2) (0, 1, 0)12 was 0.43, and the mean absolute percent error (MAPE) was 16.54. The difference of Ljung-box test of model residual sequence was not statistically significant (Q=11.06, P=0.81). The residual sequence was white noise, indicating that the model fitted well and was determined as the optimal model. The number of CRKP strains detected from January to December 2022 was used to verify the prediction effect of the model. The results showed that the actual incidence trend was in good agreement with the prediction curve, and the actual values were all within the 95% confidence interval of the predicted values, the prediction error was -33.33%25.00%, and the average relative error was 15.56%, indicating that the prediction effect of the model was good.
Conclusion
ARIMA multiplicative seasonal model can fit the time change of the number of CRKP detected in the hospital well, so it can be used for short-term prediction and dynamic analysis of CRKP epidemic trend, and provide basis for the early warning and prevention of CRKP infection in hospitals.

DOI: 10.3969/j.issn.1006-5253.2023.03.004
Guide::
Objective
To find out the dynamic change rule of surgical operation volume in a hospital from 2011 to 2020 through statistical analysis, so as to provide information reference for hospital management and medical resource allocation.
Methods
The moving average seasonal index method was used to dynamically analyze the surgical volume data from 2011 to 2020 and establish a prediction model.
Results
Except for the decline in 2020 due to the COVID-19 epidemic, the number of surgical operations in other years has increased to varying degrees, with a cumulative increase of 227.27% and an average growth rate of 8.56% per year in 10 years. In the second and third quarters of a year, the number of operations was more, and the seasonal index was more than 100%. The number of operations in the first and fourth quarters was small, and the seasonal index was lower than 1.
Conclusion
The number of surgical operations in the hospital has obvious regularity with seasonal changes. Hospital managers should reasonably allocate medical resources according to the change and development rules of surgical operations to ensure medical safety and service efficiency.

DOI: 10.3969/j.issn.1006-5253.2023.03.005
Guide::
Objective
Patients with non-small cell lung cancer (NSCLC) complicated with brain metastases (BM) have poor prognosis. This study aimed to evaluate the prognostic factors of BM in newly diagnosed NSCLC patients and construct a nomogram to predict the overall survival (OS).
Methods
We included NSCLC patients with BM diagnosed from 2010 to 2016 in SEER and they were randomly divided into the modeling group and the validation group at 7∶3. The independent prognostic factors for NSCLC with BM were determined by Cox proportional hazard regression analysis. R software was used to construct a nomogram and evaluate its differentiation, consistency and effectiveness, and finally draw a 1-3 year survival curve.
Results
We finally included 6 102 NSCLC patients with BM for analysis. Age, race, gender, histologic type, liver metastasis, lung metastasis, bone metastasis, Grade grading, T staging, N staging, surgery, chemotherapy and radiotherapy were identified as the prognostic factors for NSCLC with BM and integrated to establish the nomogram. The calibration, receiver operating characteristic curve, and decision curve analyses also showed that the clinical prediction model performed satisfactorily in predicting prognosis.
Conclusion
The construction of a clinical prediction model could effectively predict the overall survival of patients with NSCLC with BM, which has guiding significance for clinicians and patients.

Objective
To analyze the cost and postoperative rehabilitation of patients with gastric cancer undergoing robot-assisted therapy, and to evaluate the health economics of Da Vinci robot-assisted radical gastrectomy, traditional gastrectomy and laparoscopic-assisted radical gastrectomy in a hospital in Jiangsu Province.
Methods
One hundred and thirteen patients who underwent radical gastrectomy for gastric cancer in the general surgery department of Jiangsu Hospital of Traditional Chinese Medicine from July 1, 2020 to July 31, 2021 were selected as the study subjects, and were divided into 3 groups according to surgical methods: the robot-assisted laparoscopic radical gastrectomy for gastric cancer group (n=46), the traditional gastrectomy group (n=26), and the laparoscopic radical gastrectomy group (n=41). The cost, cost structure and postoperative rehabilitation indexes of the three groups of patients were compared and analyzed.
Results
1) There were significant differences in the total cost, drug cost, especially Western medicine cost, surgical consumables cost, diagnosis and treatment service cost, and inspection cost between the robot group and the open surgery group and the laparoscopic group (P＜0.05). The decrease of drug cost in the robot group was the largest, and the difference was statistically significant (P<0.05) 2) In the robot group, the ventilation time (3.02±0.33)d, defecation time (4.00±0.29)d, first oral feeding time (1.80±0.36)d, catheter removal time (0.78±0.61)d and postoperative discharge days (5.72±0.70) were significantly advanced (P＜0.05). There was no significant difference in the incidence of postoperative complications (P＞0.05). 3) There was a statistically significant difference in out-of-pocket payment between the robot group and the traditional surgery group (P＜0.05).
Conclusion
Da Vinci robot-assisted radical gastrectomy significantly reduced the drug cost of patients, greatly reduced hospital stay and achieved rapid recovery, and was as safe and effective as traditional surgery and laparoscopic techniques. It is inevitable and necessary to implement Da Vinci robotic surgery under the background of the new medical reform, which could improve the quality of medical services and save medical and health resources.

Objective
To analyze the practical application of DRG performance grouping standardized time and bed efficiency model to clinical departments, to effectively avoid the impact of different disease structures on efficiency and productivity, and to provide basis for hospital bed management and related medical resources allocation.
Methods
Patients discharged from the pediatric department in a municipal maternal and child health care institution in Zhejiang Province were selected as the research subjects. DRG group was combined with the specialized data, and the average hospitalization days and bed utilization rate were standardized by direct standardization method. The standardized results of the coverage of all the diseases were measured and compared with the traditional indicators. Time bed efficiency model was used to analyze time efficiency and bed efficiency.
Results
In the first half of 2021, the average hospitalization days and bed utilization rate of the first pediatrics department were different in the three groups of traditional, standardized and standardized coverage of all diseases; the first and second quarter values of the utilization rate of standardized beds in the first pediatrics department and standardized beds for full-coverage diseases were 45.08%, 84.17% and 56.38%, 84.64% respectively. The time and bed efficiency model showed that the three specialties in the second quarter were improved compared with those in the first quarter; the first pediatrics department was in the quadrant of high efficiency and efficiency, with an operation score of 2.25.
Conclusion
Standardized average hospital stay and bed utilization rate can promote the refined management of DRG in medical institutions and other evaluation institutions. The time-bed efficiency model can reflect resource usage more accurately and comprehensively, which is helpful for government departments and hospital managers to make development plans.

DOI: 10.3969/j.issn.1006-5253.2023.03.010
Guide::
Objective
To assess the efficacy of day surgery in reducing the hospitalization duration and cost for different diagnosis-related groups (DRGs) in a tertiary general hospital situated in Sichuan Province and to provide crucial evidence to facilitate the identification of suitable types of day surgery for screening purposes.
Methods
The information of patients undergoing surgery in a hospital from June 2021 to May 2022 was retrospectively analyzed, and the relevant data during the treatment period were collected. Patients who did not perform the day surgery mode were taken as the control group, and patients who performed the day surgery mode were taken as the observation group. SPSS was used to analyze the relevant indicators and hospitalization costs during the treatment of the two groups, and DRG evaluation system was used for evaluation.
Results
There were 1 621- patients including 543 patients with day surgery, and 1 078 hospitalized patients with elective surgery. In terms of hospital stay, day surgery was lower than elective surgery in hospital, and the difference was statistically significant (P<0.05). In terms of hospitalization costs, there was no statistically significant difference observed between the two groups in blepharon adhesion separation and extensor tendon suture (P>0.05). However, a significant difference was observed between the two groups for other surgical procedures (P<0.05). In terms of day/hospital choice composite index, the composite indexes of urethral lesion resection, transurethral ureteral stenting and fracture internal fixation removal were all<0.1, and the composite indexes of other procedures were all≥0.1 and <0.5.
Conclusion
Based on the assessment of the day/hospital choice comprehensive index, surgical procedures with lower index values can be prioritized for day surgery while maintaining the same level of safety. Conversely, surgical procedures with higher index values can be classified as general operations.

DOI: 10.3969/j.issn.1006-5253.2023.03.015
Guide::
Objective
To understand the current status and hotspots of DRG research in China in order to provide reference for the focus and direction of subsequent research.
Methods
The literatures related to DRG were retrieved from China National Knowledge Network (CNKI). Descriptive analysis was made on the number of DRG literatures and the years of publication. Social network analysis was used to analyze the core authors, cooperative groups, high-frequency keywords and their relationships in DRG literatures.
Results
There were 2 602 journal articles with the theme of ‘DRG’ or ‘diagnosis related groups’. After 2015, the number of DRG literatures in China showed a multiple increase, with the annual literatures in 2021 and 2022 exceeding 500. There were 1 072 articles from core journals (41.20%) and 1 530 articles from non-core journals (58.80%). There were 188 core authors in the field of DRG research, mainly forming 7 cooperative groups led by Hu Mu and Guo Moning, with a total of 1 425 publications (54.77%). The network cograph and centrality analysis of high-frequency keywords showed that payment method, DRG prepaid, first page of medical records , hospital management, hospitalization cost and performance evaluation were the high-frequency keywords in the field of DRG research, and their point degree centrality and proximity centrality ranked first. However, the first page of medical records and CMI were more mediation-centered.
Conclusion
The number of literatures in the field of DRG research increases rapidly in recent years, but the quality of literatures needs to be evaluated and improved. The core authors are relatively concentrated and have strong overall influence and academic leading role. The research hotspot of DRG focuses on DRG payment and DRG performance evaluation and hospital management.
