Objective:To construct a prediction model for the emergency volume of the psychiatric hospital, and analyze the changes of psychiatric emergency visits, so as to provide references for optimizing the allocation of emergency service resources.Methods:This study extracted data of the visit time of emergency patients, etc from the information system of a certain psychiatric hospital from 2018 to 2023. The monthly emergency visits (emergency volume) from 2018 to 2022 were used to construct the autoregressive integrated moving average model (ARIMA), and the monthly emergency volume from 2023 was used to validate the predictive performance of the model.Results:After model construction and screening, seasonal ARIMA (0, 1, 0) (1, 1, 1) 12 was determined as the optimal model. The predicted values of the model were in good agreement with the actual values, with an average relative error fluctuation of 1.6% to 26.8% and an average absolute error fluctuation of 9 to 159 person-time. Conclusions:The seasonal ARIMA model could accurately predict the emergency volume of a certain psychiatric hospital and provide references for human resource allocation and emergency response. However, this prediction model was suitable for short-term forecasting. If long-term forecasting was needed, continuous data fitting was necessary to ensure the effectiveness of the prediction.

Objective To forecast the national nursing human resources situation and provide policy basis for promoting the development of the nurse team.Methods The registered nurse numbers,the total population,the registered(assistant)physician numbers,and the bed numbers in medical and health institutions(in thousands)were selected from 2013 to 2023,and the bed-to-nurse ratio,doctor-to-nurse ratio,and the number of nurses per thousand population were calculated and analyzed to study the changes in national nursing human resources over the past decade.A grey GM(1,1)model was established to predict the number of nurses per thousand population from 2024 to 2030.Results ① The number of nurses per thousand population has increased year by year in the past decade,with an average annual growth rate of 11.38％;② The precision of the grey GM(1,1)model for the number of nurses per thousand population is precise(α=-0.065 9,b=2.014 1,C value=0.003 3,P=1.000),with high fitting degree.And the predicted number of registered nurses per thousand population from 2024 to 2030 are 4.291,4.584,4.896,5.229,5.585,5.965,and 6.371 respectively.Conclusion The national nursing human resources allocation has been optimized in the past decade,and the GM(1,1)model predicts that the national nursing human resources change is also in an upward trend.However,relevant policies still need to be formulated to improve the bed-to-nurse ratio and doctor-to-nurse ratio.

Objective:To investigate the current sedation level of patients with mechanical ventilation in ICU, and to explore the influence of early different sedation levels on clinical outcomes, so as to provide theoretical basis for better guidance of clinical sedation evaluation and implementation of sedation strategy management.Methods:This study was a retrospective longitudinal study. The 201 patients with invasive mechanical ventilation who underwent sedation in the Department of Intensive Care Medicine of the First Affiliated Hospital of Guangxi Medical University from January to December 2021 were selected by convenience sampling method. According to the results of Richmond Agitation-Sedation Scale(RASS), the patients were divided into deep sedation group (98 cases) and shallow sedation group (103 cases). The influencing factors of endotracheal intubation retention time and outcome were investigated by Cox multifactor analysis.Results:In the early sedation ≤48 h after the start of mechanical ventilation, 63.2%(2 143/3 389) of patients with invasive mechanical ventilation had a RASS score of shallow sedation, 35.2%(1 194/3 389) of patients with deep sedation, and 1.5%(52/3 389) of patients with insufficient sedation. Cox multivariate regression analysis showed that age, sedation level, duration of invasive mechanical ventilation and continuous renal replacement therapy were the factors influencing the indentation time of tracheal insertion ( χ2 values were 4.73 to 74.31, all P<0.05); early deep sedation was a risk factor for delayed extubation ( HR=0.499, 95% CI 0.276-0.903, P<0.05); gender, sedation level, invasive mechanical ventilation duration, acute physiology and chronic health evaluation Ⅱ scores, admission mode, continuous renal replacement therapywere the influencing factors of patient outcomes ( χ2 values were 4.41 to 26.20, all P<0.05). The deeper the sedation, the worse the patient outcomes ( HR=0.568, 95% CI 0.335-0.963 all P<0.05) . Conclusions:The early sedation level is related to the retention time and outcome of tracheal intubation in ICU patients with mechanical ventilation, and different sedation levels affect the clinical outcome of patients. The retention time of tracheal intubation in patients with shallow sedation was shortened, which was beneficial to the outcome of patients.Therefore, sedation evaluation should be strengthened in clinical work, and sedation methods should be selected according to the needs of patients. In the absence of contraindications, the shallow sedation strategy should be implemented as soon as possible. This study provides some reference and theoretical basis for the formulation and management of clinical sedation strategies.

Objective:To explore the causes and feelings of delayed experience of seeking medical treatment in patients with advanced lung cancer, and to provide new insights for more targeted health education and medical care services.Methods:A semi-structured in depth interview based on the theory of planned behavior was conducted among 30 patients with advanced lung cancer who experienced medical delay from November to December in 2021 admitted to First Affiliated Hospital of Guangxi Medical University. The interview content was analyzed and abstracted by using Colaizzi phenomenological analysis method and Nvivo11.0 software.Results:The delay duration of 30 patients with advanced lung cancer ranged from 90 to 213 days. Four subject groups were extracted by generic analysis: the cause of delay, the cause to seek medical help, the worry about the disease, and solutions.Conclusions:The delay behavior of patients with advanced lung cancer is affected by external situational factors such as symptom severity, family economic capacity, social support, accessibility of health services, prevalence of novel coronavirus, and subjective psychological factors such as sense of stigma and burden of disease, it is necessary to reduce the occurrence of medical delay in patients with advanced lung cancer through the comprehensive management strategy of multiple channels.

Objective To investigate the effects of ketamine and propofol on cardiovascular system and cognitive function in the patients with depression during the modified electroconvulsive therapy (MECT). Methods A total of 60 patients with depression treated by MECT were randomly divided into 2 groups. Induced anesthesia with ketamine and propofol were performed respectively during MECT. The course of treatment was 8 times. The mean arterial pressure(MAP)was recorded before therapy and at 5 min after MECT.Depression and the cognitive function were evaluated by using the Hamilton Depression Scale(HAMD)and the Wisconsin Card Sorting Test(WCST)before treatment and 1 day after treatment. Results There was no significant difference in MAP between the two groups after MECT(P > 0.05). The HAMD scores of the two groups were lower than those before treatment(P<0.05). In the total number of errors and the number of random errors,there was no significant difference between two groups (P > 0.05). But in completing classification of WCST ,the ketamine group was better than the propofol group(P<0.05). Conclusion Propofol has no obvious influence on the cognition function and little influence on MAP,so it could be the first choice of anaesthetic for the induction of MECT.
