Objective To explore the characteristics of exercise ventilation function in patients with chronic duration of asthma, and the correlation of cardiopulmonary exercise test and control level and conventional lung function in patients with chronic duration of asthma. Methods Seventy-three patients with chronic duration of asthma admitted from December 2021 to December 2022 were recruited in the study. The asthma control level was assessed with the asthma control test (ACT) and the patients were divided into a well-controlled group and a poorly-controlled group. Routine pulmonary function test (PFT) and cardiopulmonary exercise test (CPET) were performed in both groups, to analyze the difference of related parameters between the two groups and observe the correlation between CPET and PFT, ACT score in the patients with chronic persistent asthma. Results CPET results showed that the VE/VCO2 slope, anaerobic threshold carbon dioxide equivalent (EqCO2@AT), and physiologically ineffective peak during exercise (VD/VTpeak) were higher in the poorly-controlled group than those in the well-controlled group (all P<0.05). The peak minute ventilation (VEpeak) and tidal volume (VTpeak) of the patients in the poorly-controlled group were lower than those in the well-controlled group (both P<0.05). The peak respiratory rate (BFpeak) and respiratory reserve (BRpeak) of the two groups were not significantly different (both P>0.05). The results of correlation analysis showed that the VE/VCO2 slope, EqCO2@AT, VD/VTpeak were negatively correlated with ACT score, and VEpeak was positively correlated with FVC%pred and MMEF%pred in the patients with chronic persistent asthma. BRpeak was positively correlated with FEV1%pred, FEV1/FVC%pred, MMEF%pred in routine pulmonary function. Multivariate logistic regression analysis showed that the increase of VE/VCO2 slope and VD/VTpeak were independent risk factors for poor asthma control (P<0.05). Conclusions Patients with poorly-controlled asthma have decreased exercise ventilatory function, mainly showing decreased ventilation and tidal volume during peak exercise and decreased ventilatory efficiency. There is some correlation between exercise ventilatory function and conventional lung function of control level in patients with chronic duration of asthma. The relevant indicators of ventilation efficiency in CPET have suggestive significance for asthma that is not well controlled, so it is necessary to carry out CPET in patients with asthma to improve the comprehensive evaluation of asthma.
Objective To evaluate the pathways for improving the operational efficiency of medical teams, thereby providing micro-level empirical evidence for the refined management and high-quality development of public hospitals. MethodsBased on panel data from nine surgical teams in the Department of Thoracic Surgery at Sichuan Cancer Hospital from 2021 to 2024, this study employed the data envelopment analysis (DEA) with the BCC model to assess static efficiency, including technical efficiency (TE), scale efficiency (SE), and overall efficiency (OE). The Malmquist index was used to analyze the dynamic total factor productivity (TFP) and its decomposition into efficiency change (EC) and technology change (TC). Input indicators were the number of physicians and the number of open beds. Output indicators included the proportion of surgical patients, the proportion of grade Ⅳ surgeries, and the average length of stay (reciprocally transformed for positive orientation). Results The mean OE of all medical teams showed a continuous upward trend, while the mean SE exhibited a “V-shaped” pattern, initially decreasing and then increasing. The most significant growth was observed in mean TE, which was the primary driver of the OE improvement. All medical teams achieved positive TFP growth, with TC values greater than 1.000 across all teams, indicating that technological innovation was the core engine of efficiency enhancement. However, EC showed a divergent trend among the teams. Conclusion Public hospital performance appraisal policies effectively guide technological upgrading of medical teams through indicators such as “proportion of discharged patients undergoing surgery” and “proportion of grade Ⅳ surgeries”. However, issues of hospital resource mismatch and SE differentiation persist. It is necessary to establish specialized operation groups for dynamic resource monitoring and construct a “technological upgrading, scale adaptation, and management innovation” triangular balanced system to achieve a sustainable mechanism for maximizing healthcare resource input-output.
Day surgery is one of the key tasks of the national medical reform. It is still in the stage of rapid developing in the country. It is the responsibility of the large general hospitals to explore the effective management mode of the day surgery center to meet the clinical quality and safety. During the establishment and management of day surgery center in general hospital, it is needed to build a strong specialized day surgery team through professional training, and to establish a coordination and incentive mechanism for the cooperation between the day ward and the specialized subjects by introducing lean thinking strategy. According to the characteristics of day surgery, the clinical pathway management and the whole course rehabilitation and the health education system of day surgery are established. The formulate norms for medical records of day surgery will be built. The monitoring system for the efficiency and safety of day surgery is established to improve the medical quality and safety of day surgery. As a result, the model of day surgery that conforms to the medical characteristics of China will be established.
Objective To understand the current situation of medical service and management in Luxi township health center (LxC) in Yongxin county of Jiangxi province, so as to provide baseline data about drug allocation, logistic key techniques research and products development for township health centers. Methods By means of questionnaire and focus interview, the LxC was investigated from the following aspects: general information, human resources, medicine list, basic device configuration, medical service and management, as well as service efficiency. Results a) Yongxin county including 13 village committees covers an area of 86 km2, with the population of 22 300 in 2009, and it pertains to a backward area with the annual per capita income of RMB 4 100 yuan; b) Among the total 28 staffs in LxC, 78.6% were health workers; the general practitioner (GP)/nurse ratio was about 1?0.58; the proportion of GP, nurses, medical technicians, other staffs was 54.55%, 31.82%, 9.09% and 4.54%, respectively; the proportion of bachelor degree, junior college graduation and secondary technical school graduation was 9.1%, 13.6%, and 77.3%, respectively; and the ratio of elementary, middle, and high professional title of health workers was 15?5?1; c) There were 625 species of drugs in LxC in 2009, and the hospital beds approved by government were 0.69 per thousand agricultural persons, which, however, were 1.15 in fact. The rate of 51 basic equipments shown in national regulation was actually 76.5%, and the readiness and utilization rate of existing 40 equipments was 92.5%; and d) In 2009, the outpatients were 12 150 person-time, with the average cost of RMB 29.39 yuan; the hospital discharge was 1 589 person-time, with the average stay of 12 days and the average cost of RMB 490.05 yuan; the vaccine inoculations were 5 053 person-time; among the total income, the medical service income accounted for 73.2%, while the drug income accounted for 53.7%; the personnel expenditure was 31.0% of the total, and the balance of income and expenditure was RMB –263 500 yuan. Conclusion The hardware condition of LxC is not so good owing to the financial difficulties of Yongxin county and Jiangxi provincial government. In comparison with the whole country, although the professional title structure is ok, health workers are still not enough, with unreasonable specialty structure and low educational background. The rate of basic equipments and the approved hospital beds per thousand agricultural persons are low. There are 625 species of drugs, containing 218 species shown in 2009 national essential medicine list. And the other conditions are as follows: no information system, lack of public health service, short of financial input, high ratio of “running hospital by selling drugs”, and low efficiency of medical service. So the top priority of LxC construction should be figuring out all of the above issues, and better serving the people.
Objective To analyze the current situation of the centralized treatment mode for daytime treatment (excluding daytime surgery) services in a large-scale military hospital, and provide practical support for the management and operation of the centralized treatment mode for daytime treatment. Methods Data on patients undergoing centralized daytime treatment in the Department of Ambulatory Medicine, First Medical Center of PLA General Hospital were retrospectively collected between February 7, 2021 and December 31, 2023. The patients’ condition, daytime treatment operation indicators, and quality control indicators were statistically analyzed. Results A total of 14903 patients underwent daytime treatment, including 8548 females and 6355 males. The patients’ age ranged from 18 to 74 years old. There were 9757 patients (65.47%) who had been hospitalized ≥ 2 times. The main payment method for patients was medical insurance (83.16%). Breast cancer accounted for the highest proportion (26.45%). The main treatment methods for patients were targeted therapy and immunotherapy (68.03%). The patients experienced a total of 1146 drug-related adverse reactions, mainly involving anti-tumor drugs. Among them, 15 cases were drug-related adverse reactions treated on the day of treatment, and the other 1131 cases were drug-related adverse reactions that occurred outside the hospital. After optimizing the entire process of daytime hospitalization (timed based treatment) in January 2023, compared to 2022, the average waiting time for patients after admission was reduced by 26.89%, the bed utilization rate increased by 9.09%, and patient satisfaction increased to 98.98%. In 2023, the default rate of daytime treatment was 1.15%, the cancellation rate of daytime treatment on the day of treatment was 4.39%, and the discharge follow-up rate reached 100%. Conclusions The daytime treatment under the centralized treatment mode in the the Department of Ambulatory Medicine, First Medical Center of PLA General Hospital focuses on breast cancer patients, and the main treatment methods are targeted therapy and immunotherapy. Time based treatment is beneficial for shortening the average waiting time of patients after admission, improving bed utilization and patient satisfaction.
Objective To analyze the dynamic efficiency of township hospitals. Methods Based on the DEA-Malmquist index, this research analyzed the change of the total factor productivity indices and the decomposition items of 281 township hospitals in Hunan province with panel data from 2000 to 2008. Results Among 281 township hospitals, less than half increased their scale efficiency, while more than half increased their total factor productivity, technology, whole efficiency and technical efficiency. Increasing technology and whole efficiency was the best way to improve total factor productivity. Besides, increasing technical efficiency and scale efficiency was the best way to improve whole efficiency. Conclusions The improvement of scale efficiency is key to developing the central township hospitals, while the improvement of technology is the key to developing general township hospitals.
ObjectiveTo measure the total factor productivity and its component changes of public secondary general hospitals in China from 2012 to 2018.MethodsFrom February to September in 2019, stratified systematic sampling method was used to collect the panel data of input and output indicators from 2012 to 2018 of 511 public secondary general hospitals in 5 provinces of China (Shandong, Hubei, Hainan, Anhui, and Shanxi), and Bootstrap-Malmquist-data envelopment analysis was used to calculate the total factor productivity and its component changes of the hospitals.ResultsFrom 2012 to 2018, the total factor productivity of the 511 public secondary general hospitals decreased by 0.22%, technical efficiency decreased by 5.24%, technical changes increased by 5.29%, pure technical efficiency decreased by 1.40%, and scale efficiency decreased by 3.89%, respectively.ConclusionsIn the past 7 years, the total factor productivity of public secondary general hospitals in China has declined slightly, mainly due to the decline of scale efficiency and pure technical efficiency, and the technological progress is the main reason for its improvement. The implications for the public secondary general hospitals are three folds: avoiding blind expansion and exploring optimum scale of beds, strengthening the internal fine management to improve the management practice and technical efficiency, and promoting technological progress by healthcare cooperating organizations.
There are few researches on the modulation effect of transcranial direct current stimulation(tDCS) on complex spatial cognition. Especially, the influence of tDCS on the neural electrophysiological response in spatial cognition is not yet clear. This study selected the classic spatial cognition task paradigm (three-dimensional mental rotation task) as the research object. By comparing the changes in behavior and event-related potentials in different modes of tDCS before, during and after the application of tDCS, this study analyzed the behavioral and neurophysiological effects of tDCS on mental rotation. The comparison between active-tDCS and sham-tDCS showed no statistically significant difference in behavior between different stimulation modes. Still, the changes in the amplitudes of P2 and P3 during the stimulation were statistically significant. Compared with sham-tDCS, the amplitudes of P2 and P3 in active-tDCS mode showed a greater decrease during the stimulation. This study clarifies the influence of tDCS on the event-related potentials of the mental rotation task. It shows that tDCS may improve the brain information processing efficiency during the mental rotation task. Also, this study provides a reference for an in-depth understanding and exploration of the modulation effect of tDCS on complex spatial cognition.
Epilepsy is a neurological disease with disordered brain network connectivity. It is important to analyze the brain network mechanism of epileptic seizure from the perspective of directed functional connectivity. In this paper, causal brain networks were constructed for different sub-bands of epileptic electroencephalogram (EEG) signals in interictal, preictal and ictal phases by directional transfer function method, and the information transmission pathway and dynamic change process of brain network under different conditions were analyzed. Finally, the dynamic changes of characteristic attributes of brain networks with different rhythms were analyzed. The results show that the topology of brain network changes from stochastic network to rule network during the three stage and the node connections of the whole brain network show a trend of gradual decline. The number of pathway connections between internal nodes of frontal, temporal and occipital regions increase. There are a lot of hub nodes with information outflow in the lesion region. The global efficiency in ictal stage of α, β and γ waves are significantly higher than in the interictal and the preictal stage. The clustering coefficients in preictal stage are higher than in the ictal stage and the clustering coefficients in ictal stage are higher than in the interictal stage. The clustering coefficients of frontal, temporal and parietal lobes are significantly increased. The results of this study indicate that the topological structure and characteristic properties of epileptic causal brain network can reflect the dynamic process of epileptic seizures. In the future, this study has important research value in the localization of epileptic focus and prediction of epileptic seizure.
