Objective To explore the influencing factors and improving measures of hand hygiene among healthcare workers. Methods From June to August 2016, several healthcare workers from clinical departments and nosocomial infection control department in Chengdu were selected by purposive sampling method. Data was collected by individual in-depth interviews, and was three-rank coded by Nvivo 8 software based on Grounded Theory. Results After three-rank coding, 6 important influencing factors were generalized which were re-categorized into 3 levels: personal cognition, behavior capacity and social support. At the last, the whole framework of the theory was constructed through core coding. Conclusion In clinical practice, we should take reasonable measures to strengthen the training of hand hygiene, improve the hand hygiene facilities, strengthen supervision and management, and effectively improve the implementation rate of hand hygiene.
ObjectiveTo explore the application of PDCA cycle in the examination of medical quality of Tibetan area hospitals. MethodsIn the October 2014, PDCA cycle theory was introduced into the examination of Tibetan hospital medical quality. We collected quality problems existing in the medical activities actively, analyzed the reason and influencing factors and made corresponding plans. Then we implemented the plans and measures strictly, surveyed the results, found out and analyzed the problems, summarized the results of the examination, and turned the unsolved problems to the next PDCA circulation. Continuous follow-up was performed until the results were satisfactory. Based on Sichuan Province Secondary Comprehensive Hospital Evaluation Standard, we analyzed the medical quality of the hospital before PDCA application (July to September 2014) and after PDCA application (October to December 2014). ResultsThe incidence of medical nursing documents writing defects decreased from 12.4% to 5.9%. Hospital infection management defect rate declined from 13.5% to 5.3% and drug safety management defect rate declined from 11.8% to 2.5%, and all the differences were statistically significant (P<0.05). ConclusionPDCA cycle in the Tibetan hospital for medical quality examination has greatly improved the medical quality of Tibetan hospitals.
Objective To investigate the method and effect of continuous improvement of adverse drug reaction (ADR) monitoring in a major public hospital’s cooperating branch hospital. Methods PDCA cycle management was used to continuously improve the quality of ADR monitoring. ADR report network platform was established in the fourth quarter of 2014; ADR report specification training for the medical personnel was held in the first quarter of 2015; a examine mechanism was built in the second quarter of 2015. The quality and quantity of ADR monitoring before and after the PDCA cycle management were analyzed. Results ADR report timeliness conform to the requirements increased from 45.5% (from the first to third quarter of 2014) to 98.1% (from the fourth quarter of 2014 to the second quarter of 2015); accurate ADR types checking, normal name writting, and complete process description increased from 68.6%, 65.7%, 8.6% (from January 2014 to Frequency 2015) to 92.9%, 96.4%, 85.7% (from March to June 2015); the quantity of ADR report was obviously improved. Conclusion Learning from public hospital’s experience and considering its own condition in ADR monitoring, cooperating branch hospital utilizes PDCA cycle management which could continuously improve the ADR monitoring.
Objective To analyze the application of lean healthcare management in optimizing services in foreign operating rooms, and provide a theoretical reference for further optimizing service processes in domestic operating rooms with lean healthcare management. Methods PubMed and Web of Science databases were searched literature about lean healthcare management in optimizing foreign hospital operating room service process. The search period was from the establishment of databases to November 2024. The number of publications, publishing institutions, authors, citation frequencies, keywords, the use of lean management tools and the improvement status were analyzed.Results A total of 71 literatures were included. Among them, 17 literatures were published from 2008 to 2014, and the number of related literatures increased significantly since 2015, with 54 literatures published by 2024; 9 literatures were published by universities and 62 literatures were published by hospitals. In terms of the distribution of countries and regions where the literatures were published, there were 34 literatures from the United States, 12 from the United Kingdom, 5 from Italy, 4 from Switzerland, and 3 from Canada. The keywords basically presented the combination ofthemes related to operating room management and lean healthcare management improvement fields, such as lean six sigma, quality improvement, and operating room efficiency. The five lean tools with the highest frequency of occurrence in the 71 included literatures were value stream mapping, fishbone diagram, A3 report, PDCA cycle management, and 5S. Conclusions There is an imbalance in the development of lean healthcare management research, with the number of publications in developed countries being far higher than that in developing countries. Lean healthcare management is conducive to improving surgical safety, work efficiency, and patient-doctor satisfaction. Lean healthcare management should further adapt to the actual situation, unify the lean management indicators in operating rooms, conduct cross-departmental cooperation, maximize the effectiveness of lean improvement tools, and achieve modern medical management.

Objective To establish dog model of testicular autotransplantation with a modified technique.Methods Testicular autotransplantations were performed on the right side of 30 male dogs, whose ages ranged from 1.5 to 2.0 years old and weights ranged from 14 to 17 kg. After the spermatic artery with a cuff of abdominal aorta and spermatic vein and with a cuff of inferior vena cava were detached, the testis was perfused and kept at icing temperature. An end-to-side anastomosis of the spermatic vessels to the external iliac vessels was conducted subsequently. The survival conditions of the auografts were assessed by digital subtraction arteriography (DSA). Histological examination and detection on the serum levels of follicle stimulating hormone (FSH), luteotrophic hormone (LH), and testosterone (T) were made at two weeks intervals. Results Of the 30 testicular autotransplantations performed, 27 cases were successful. The success rate was 90%. The time of heat ischemia, cold ischemia, anastomosis of spermatic vessels, and total operation was 4.5±0.9 minutes, 50.0±10.0 minutes, 35.5±5.5 minutes, and 3.5±0.5 hours respectively. DSA proved that the testis survived well. No morphological abnormality was found at different stages of the spermatogenic cells. The LH level was higherthan that before operation, being statistically different (Plt;0.05);however, the levels of FSH and T did not changed significantly (Pgt;0.05). Conclusion A stable and feasible model of testicular autotransplantation is established and it provides a reliable experimental platform for human testicular transplantation.

In the process of lower limb rehabilitation training, fatigue estimation is of great significance to improve the accuracy of intention recognition and avoid secondary injury. However, most of the existing methods only consider surface electromyography (sEMG) features but ignore electrocardiogram (ECG) features when performing in fatigue estimation, which leads to the low and unstable recognition efficiency. Aiming at this problem, a method that uses the fusion features of ECG and sEMG signal to estimate the fatigue during lower limb rehabilitation was proposed, and an improved particle swarm optimization-support vector machine classifier (improved PSO-SVM) was proposed and used to identify the fusion feature vector. Finally, the accurate recognition of the three states of relax, transition and fatigue was achieved, and the recognition rates were 98.5%, 93.5%, and 95.5%, respectively. Comparative experiments showed that the average recognition rate of this method was 4.50% higher than that of sEMG features alone, and 13.66% higher than that of the combined features of ECG and sEMG without feature fusion. It is proved that the feature fusion of ECG and sEMG signals in the process of lower limb rehabilitation training can be used for recognizing fatigue more accurately.
