Objective:To construct a comprehensive performance evaluation index system based on diagnosis related groups(DRG) and analyze the overall performance of a hospital before and after the implementation of DRG payment using an improved radar chart method.Methods:A literature analysis method was employed to preliminarily determine the performance evaluation framework in combination with the actual situation of the hospital. Subsequently, the Delphi method was used to establish a comprehensive performance evaluation index system based on DRG. Data related to inpatients from 2019 to 2022 (with 2019 being the period before the implementation of DRG payment) were extracted from the hospital information system and medical insurance system of a tertiary general hospital in Liaoning Province. The improved radar chart method was then utilized to conduct a comprehensive performance evaluation of the hospital.Results:The comprehensive performance evaluation index system based on DRG included five first-level indicators (service capacity, service efficiency, medical quality, medical safety, and revenue and costs) and 19 second-level indicators. The weights of medical quality and medical safety were the highest, both at 0.212. The evaluation results using the improved radar chart method showed that the comprehensive performance values of the hospital from 2019 to 2022 were 0.427 0, 0.463 3, 0.505 2, and 0.545 0, respectively. Overall, the five first-level indicators showed an improving trend, but the development of service capacity, service efficiency, medical quality, and revenue and costs was more balanced compared with medical safety.Conclusions:With the implementation of DRG payment reform, the performance of the hospital has improved and was trending towards more balanced development. The evaluation index system constructed in this study is scientifically sound and feasible. Combined with the improved radar chart method, it can more intuitively reflect changes in hospital performance and can serve as a reference for performance evaluation in public hospitals.

Objective:To evaluate the obesity factor on ventilator-induced lung injury (VILI) in rats.Methods:Forty-five clean-grade male Sprague-Dawley rats, aged 6-8 weeks, were divided into 3 groups ( n = 15 each)according to the body weight: normal weight control group (group C), normal weight VILI group (group CV) and obese VILI group (group FV). The body weight was 233-267 g in C and CV groups and 288-332 g in FV group.In group C, the tidal volume (V T) was 10 ml/kg.In CV and FV groups, the rats were ventilated for 4 h with the V T set at 40 ml/kg, respiratory rate 40 breaths/min, inspiratory/expiratory ratio 1∶2, PEEP 0 mmHg, and fraction of inspired oxygen 21% to establish the VILI model.The arterial blood samples were collected immediately before tracheal intubation and at 4 h of mechanical ventilation for blood gas analysis and PaO 2 recording.The remaining blood samples were used for plasma collection.The rats were sacrificed after blood collection at 4 h of ventilation, and the bilateral lung tissues were isolated to collect the bronchoalveolar lavage fluid (BALF). The concentrations of leptin in plasma and tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and interleukin-6 (IL-6) in plasma and BALF were detected by enzyme-linked immunosorbent assay.The wet/dry weight (W/D) ratio of lung tissues was measured.The pathological changes of lung tissues were observed after HE staining, and the lung injury score was evaluated.The expression of NF-κB p65 in lung tissues was detected by Western blot. Results:Compared with group C and group CV, the plasma leptin concentration was significantly increased in group FV( P<0.01). Compared with group C, the concentrations of TNF-α, IL-6 and IL-1β in plasma and BALF were significantly increased, PaO 2 was decreased, the lung injury score and W/D ratio of lung tissues were increased, and NF-κB p65 expression was up-regulated at 4 h of ventilation in CV and FV groups ( P<0.01). Compared with group CV, the concentrations of TNF-α, IL-6 and IL-1β in plasma and BALF were significantly decreased, PaO 2 was increased, the lung injury score and W/D ratio of lung tissues were decreased, and NF-κB p65 expression was down-regulated at 4 h of ventilation in group FV ( P<0.05). Conclusion:Obesity factor can reduce VILI in rats, and the mechanism may be related to the increase in plasma leptin levels.

Objective: To evaluate the effect of penehyclidine hydrochloride on the expression of airway mucin 5AC (MUC5AC) during ventilator-induced lung injury (VILI) and the relationship with Toll-like receptor 4/myeloid differentiation factor 88 (TLR4/MyD88) signaling pathway in rats. Methods: Thirty-six clean-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-250 g, were divided into 3 groups (n=12 each) using a random number table method: sham operation group (group S), VILI group (group VILI), and penehyclidine hydrochloride group (group P). The rats were tracheotomized in group S. The rats were tracheotomized, connected to a small animal ventilator and mechanically ventilated for 4 h with the tidal volume of 20 ml/kg, respiratory rate 80 breaths/min, inspiratory/expiratory ratio 1∶1, and inspired oxygen fraction ratio 21% in VILI and P groups.At 30 min before mechanical ventilation, penehyclidine hydrochloride 2 mg/kg was injected via the tail vein in group P, and the equal volume of normal saline was given instead in S and VILI groups.At 4 h of mechanical ventilation, the arterial blood samples were taken for measurement of PaO₂.The rats were then sacrificed, and broncho-alveolar lavage fluid (BALF) was collected for determination of interleukin-1β (IL-1β), IL-6 and tumor necrosis factor-α (TNF-α) concentrations by enzyme-linked immunosorbent assay.The lung specimens were collected for calculation of the wet/dry weight ratio (W/D ratio), for examination of pathological changes which were scored after haematoxylin and eosin staining (under a light microscope), and for determination of the expression of MUC5AC (by immunohistochemistry), expression of TLR4, MyD88, p38 mitogen-activated protein kinase (p38MAPK) and nuclear factor-kappa B (NF-κB) in lung tissues (by Western blot), and expression of MUC5AC mRNA in lung tissues (by real-time polymerase chain reaction). Results: Compared with group S, PaO₂ was significantly decreased, the W/D ratio and lung injury score were increased, the expression of MUC5AC protein and mRNA was up-regulated, the concentrations of IL-1β, IL-6 and TNF-α in BALF were increased, and the expression of TLR4, p38MAPK, MyD88 and NF-κB was up-regulated in VILI and P groups (P<0.01). Compared with group VILI, PaO₂ was significantly increased, the W/D ratio and lung injury score were decreased, the expression of MUC5AC protein and mRNA was down-regulated, the concentrations of IL-1β, IL-6 and TNF-α in BALF were decreased, and the expression of TLR4, p38MAPK, MyD88 and NF-κB was down-regulated in group P (P<0.05). Conclusion Penehyclidine hydrochloride can decrease the expression of airway MUC5AC during VILI, and the mechanism may be related to inhibiting activation of TLR4/MyD88 signaling pathway in rats.
