Objective:To analyze the changes and structural variations in hospitalization costs for patients with lung malignancies after the implementation of diagnosis-intervention packet (DIP) payment system, and to evaluate its effectiveness.Methods:Data from the first page of medical records and hospitalization cost data from the hospital information system of a tertiary general hospital in Henan Province were extracted for patients diagnosed with lung malignancies from 2020 to 2023. The data were divided into pre-implementation group (2020—2021) and post-implementation group (2022—2023) based on the implementation time of DIP. Chi-square test, t test, and Wilcoxon rank-sum test were used to analyze the differences in basic characteristics and hospitalization costs of patients with lung malignancies before and after the implementation of DIP. Grey relational analysis was employed to examine the internal associations between total hospitalization costs and various cost components. Structural variation analysis was used to assess the changes in the structure of hospitalization costs after the implementation of DIP. Results:A total of 14 587 hospitalized patients with lung malignancies were included, with 6 807 cases in the pre-implementation group and 7 780 cases in the post-implementation group. The average length of hospital stay decreased from (13.17±6.74) days before implementation to (12.02±6.49) days after implementation ( P<0.05). The proportion of level-four surgeries increased from 46.4% to 57.0% ( P<0.05). The average hospitalization cost per patient with lung malignancies decreased from 56 952 yuan before DIP implementation to 55 560 yuan after implementation ( P<0.05). For patients with lung malignancies diagnosed as C34.1, C34.2, C34.3, and C34.8, the top four cost components most strongly associated with total hospitalization costs were treatment costs, material costs, comprehensive medical service costs, and diagnostic costs, with correlation coefficients all>0.80. For patients with C34.9, the top four cost components most strongly associated with total hospitalization costs were treatment costs, comprehensive medical service costs, diagnostic costs, and Western medicine costs, with correlation coefficients>0.95. For patients diagnosed as C34.1, C34.2, C34.3, and C34.9, diagnostic costs, Western medicine costs, and material costs contributed significantly to the structural variation of hospitalization costs, with contribution rate of structure variation all exceeding 75%, among which Western medicine costs and material costs showed negative variation. For patients diagnosed as C34.8, treatment costs, Western medicine costs, and material costs contributed significantly to the structural variation of hospitalization costs, with contribution rate of structure variation all exceeding 80%, among which Western medicine costs showed negative variation. Conclusions:The implementation of DIP reduced the hospitalization costs for patients with lung malignancies, optimized the structure of hospitalization costs, improved the efficiency of medical services, and promoted the rational allocation of medical resources.

To deeply explore the load experience of primary caregivers of colorectal stoma patients, analyze their psychological load, understand their load experience when caring for patients, so as to provide theoretical basis for promoting patients’ home rehabilitation and continuous nursing. A semi-structured interview was conducted with the primary caregivers of 10 patients with permanent stoma in a tertiary hospital in Xi’an using a phenomenological research method, and the data were summarized and refined by Colaizzi 7-step analysis. A total of four themes were extracted: complex emotional reactions, lack of knowledge about stoma care, a huge care load on the shoulder, and social and financial support needed. The primary caregivers of colorectal stoma patients have a certain degree of care load in the daily care of the patients. Health care professionals should pay attention to the psycho-emotional changes of these individuals and take targeted interventions to reduce the psychological load of the caregivers and improve the quality of life of the patients and their caregivers.

Objective This study prepared gelatin three-dimensional porous microspheres and investigated the feasibility of gelatin three-dimensional porous microspheres loaded with quercetin(G-quercetin)as bone tissue scaffold material.Methods Porous gelatin microspheres were prepared by emulsification and loaded with quercetin by lyophilization.Scanning electron microscopy was used to ob-serve morphology of the microspheres.The cytotoxicity of G-quercetin microspheres and their effects on the adhesion,proliferation and differentiation of mouse embryonic osteoblast precursor cells(MC3T3-E1)were detected by immunofluorescence staining,live/dead cell staining and CCK-8 assay,alkaline phosphatase(ALP)staining and alizarin red staining.RT-PCR was used to detect the tran-scriptional levels of osteoblast-related cytokines such as Runx-2,ALP,OPN and OCN.Results The scanning electron microscopy re-sults showed that the prepared three-dimensional microporous material loaded with quercetin gelatin had a porous structure.Cell adhe-sion showed that the cells could spread well on the surface of the microspheres.Compared with the control group,the results of live/dead cell staining and CCK-8 detection showed that the microspheres had no significant cytotoxicity(P＞0.05).Compared with the con-trol group,G-quercetin microspheres showed an increase in ALP expression and mineralization in vitro.PCR results also showed a sig-nificant increase in Runx-2,ALP,OCN,OPN(P＜0.05).Conclusion The G-quercetin porous microspheres prepared in this experi-ment have good biocompatibility and can promote the osteogenic differentiation of MC3T3-E1 in vitro.It is expected to be used as a new scaffold material for bone tissue engineering.

Objective:To develop a Quality of Life Scale for Enterostomy Patients in lines with my country's cultural background and medical system.Methods:The initial version of the scale was formed through literature review, brainstorming, and the expert consultation. From July 2018 to February 2019, we selected 212 enterostomy patients from five ClassⅢ Grade A hospitals, namely the First Affiliated Hospital of Xi'an Jiaotong University, the Second Affiliated Hospital of Xi'an Jiaotong University, Shaanxi Provincial People's Hospital, Xijing Hospital of Air Force Medical University and Tangdu Hospital of Air Force Medical University for field investigation by convenient sampling. We formed the final scale with the method of item screening, and evaluated its reliability as well as validity.Results:The final version of the scale extracted six common factors belonging to three dimensions, a total of 30 items, explaining 61.7% of the variance. The Cronbach's α coefficient of the total scale was 0.921, the split-half reliability coefficient was 0.945; Cronbach's α coefficients of each dimension ranged from 0.731 to 0.899, and split-half reliability coefficients were from 0.757 to 0.936. The item content validity ranged from 0.82 to 1.00, and the correlation coefficient with the criterion, the total score of the Standardized Quality of Life Scale for Ostomy Patients was 0.756. The Spearman correlation coefficients among dimensions, as well as between dimension and total score were from 0.282 to 0.739 (all P<0.01) . Conclusions:The Quality of Life Scale for Enterostomy Patients has good reliability and validity which can be used to evaluate the quality of life of enterostomy patients under the cultural background of our country.

Objective To investigate the effect of FOCUS-PDCA program on pressure ulcers nursing quality management. Methods By using the 9 steps of FOCUS-PDCA program of exploring, organizing, clarifying, understanding, selecting, planning, enforcing, checking and executing, we looked into the primarily factors for pressure ulcers and modified and improved our pressure ulcer nursing management system. Then training was done to the nurses, and the pressure ulcer management system was used. The effects in implementation of pressure ulcers prevention, mastery of pressure ulcers prevention knowledge among nurses and occurrence of pressure ulcers in the high-risk patients were studied after applying the program. Results After use of FOCUS-PDCA program, the qualification rate of pressure ulcers prevention implementation and mastery of pressure ulcers prevention knowledge were both higher than before the use. The occurrence rate of pressure ulcers in the high-risk patients was lower than before the use (P<0.05). Conclusion By using the FOCUS-PDCA program in the nursing quality management for patients with pressure ulcers, we can effectively improve the implementation of pressure ulcers preventive measures, enhance the nursing staff to master knowledge on pressure ulcers and reduce the incidence of pressure ulcers.
