Objective:To evaluate the performance of key performance indicator (KPI) lean teaching management system in clinical medical laboratory.Methods:Combining lean teaching management in universities with KPI system of enterprises, an innovative KPI lean teaching management system was developed and applied in Clinical Medical Laboratory of Guangdong Provincial People′s Hospital (GDPH). A total of 106 teachers, who had worked from January 2021 to December 2022 in GDPH, joined this study. Teachers were divided into 8 professional groups. Firstly, we quantified the teaching workload by class hours, evaluated the teaching outcomes base on national, provincial, school, and college levels to assign different teaching points, and linked the teaching KPI scores to the evaluation, salary, and professional title of teachers. Then, we analyzed the overall teaching points and teaching points for each professional group (2021-2022). Finally, we asked teaching managers, teachers, and colleagues to evaluate the KPI lean teaching management system and compared the effects before and after the implementation of this system.Results:Compared with 2021, the teaching scores of 106 teachers increased significantly from 1.0 (0.2, 2.7) to 3.8 (2.3, 6.0) in 2022 ( Z=8.1, P<0.01). The teaching scores of clinical molecules, clinical coagulation, clinical immunology, clinical microbiology, Huifu laboratory, and clinical biochemistry group were significantly higher in 2022 than the scores they got in 2021 (all P<0.05). Compared with 2021, there were 3 new set up of educational reform projects, 2 submitted teaching articles, 3 new competition awards, 7 outstanding teachers, and 5 outstanding students in 2022. After application of KPI lean teaching management, the evaluation scores of teaching work by teaching managers, teachers, and colleagues are all significantly improved ( P<0.05). Conclusion:KPI lean teaching management system could effectively enhance teachers′ work initiative, improve teaching efficiency and outcome, and promote the teaching quality. Therefore, based on the performance of KPI lean teaching management system in our study, it is possible to realize its potential in terms of lean management in clinical medical laboratory.

Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems in the world. Pharmaceutical industry is an important part of China's national economy. At present, there are few related studies reported at home and abroad. Objective To investigate the status and influencing factors of WMSDs in chemical pharmaceutical industry. Methods A cross-sectional epidemiological survey was conducted among all workers from three chemical pharmaceutical enterprises in Guangzhou. The Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, symptoms of musculoskeletal disorders, types of work, work organization, and and work postures. Multiple logistic regression method was used to analyze the risk factors of WMSDs in chemical pharmaceutical workers. Results In this study, 563 workers were selected as subjects. The total prevalence rate of WMSDs symptoms in the chemical pharmaceutical workers was 43.9% (247/563), and the leading body part-specific prevalence rate from high to low was 34.3% in the lower back, 24.3% in the upper back, 24.0% in the shoulders, and 23.8% in the neck. The prevalence rate of WMSDs symptoms in multiple body parts (30.0%) was 2.16 times higher than that in single body part (13.9%), and the prevalence rate of WMSDs symptoms in four body parts was the highest (11.4%). The results of multiple logistic regression analysis showed that age ≥50 years (reference age <30 years) (OR=2.140, 95%CI: 1.054-4.345), often or very often (reference never/rarely) long-time head rotating (OR=2.695, 95%CI: 1.753-4.142) and long-time keeping arms above shoulders (OR=1.902, 95%CI: 1.108-3.265) increased the risk of reporting WMSDs symptoms (P<0.05). Regarding education level, workers with high school and technical secondary school (OR=0.333, 95%CI: 0.175-0.636) or college and above (OR=0.413, 95%CI: 0.216-0.790) education had a lower risk of reporting WMSDs symptoms than those with middle school or below (P<0.05). Conclusion The prevalence rate of reporting WMSDs symptoms in chemical pharmaceutical industry is high, the involving body parts are lower back, upper back, shoulders, and neck, and reporting simultaneous occurrence of WMSDs symptoms in multiple body parts is common. The chemical pharmaceutical manufacturers can reduce the risk of WMSDs by strengthening the training on workers' ergonomics knowledge, paying attention to the less educated personnel, protecting the elderly workers, and avoiding awkward work postures, like rotating head for a long time and raising arms over shoulders.

OBJECTIVE: To investigate the effect of body mass index (BMI) on the short-term effectiveness of high tibial osteotomy (HTO) in the treatment of varus knee arthritis. METHODS: The clinical data of 84 patients (84 knees) with varus knee arthritis treated with HTO between May 2016 and August 2020 were retrospectively analyzed. According to BMI, the patients were divided into normal group (32 patients in group A, BMI<25 kg/m ²), overweight group (27 patients in group B, BMI>30 kg/m ²), and obese group (25 patients in group C, BMI>30 kg/m ²). The BMI of groups A, B, and C were (23.35±0.89), (26.65±1.03), and (32.05±1.47) kg/m ², respectively. There was no significant difference ( P>0.05) in gender, age, surgical side, disease duration, and preoperative Hospital for Special Surgery (HSS) score, visual analogue scale (VAS) score, knee range of motion, and hip-knee-ankle angle (HKA) between groups. The operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation were recorded and compared between groups. The improvement of knee joint function and pain status were evaluated by knee joint HSS score, knee range of motion, and VAS score before and after operation, and measuring the HKA of patients on X-ray film. During the follow-up, the X-ray films of the knee joint were reexamined to observe the position of the internal fixator and the healing of osteotomy. RESULTS: All patients completed the operation successfully and were followed up 8-40 months (mean, 19.3 months). There was no significant difference in follow-up time, operation time, intraoperative dominant blood loss, and the decrease of hemoglobin on the 3rd day after operation between groups ( P>0.05). No operative complications such as severe vascular or nerve injury occurred. After operation, deep venous thrombosis of lower extremities occurred in 1 case in groups A and B respectively, and fat liquefaction of surgical incision occurred in 2 cases in group C. There was no significant difference in the incidence of perioperative complications between groups (3.1% vs. 3.7% vs. 8.0%) ( P=0.689). During the follow-up, there was no bone nonunion, plate fracture or loosening. At last follow-up, HSS score, VAS score, knee range of motion, and HKA significantly improved in the 3 groups when compared with those before operation ( P<0.05), but there was no significant difference in the differences of the above indexes between groups before and after operation ( P>0.05). CONCLUSION BMI does not affect the short-term effectiveness of HTO in the treatment of varus knee arthritis. HTO can be selected for overweight and obese patients after standard medical treatment is ineffective.

Education, marriage, nurses′judgment on the necessity of the service and their own subjective judgment of their competence were the factors affecting nurses′ participation in the Internet plus nursing service.Conclusions:Multiple factors affect the choice of nursing staff′s behavior in Internet plus nursing service.From the perspective of nursing staff, the Internet plus nursing service mode needs joint efforts from many aspects.

Objective:To study the relationship between compartmental kneeosteoarthritis (KOA) and osteoporosis (OP).Methods:A total of 118 KOA patients with 50~80 years old and 16.5~38 of body mass index (BMI) were selected as the KOA group, in which the patient with OP caused by secondary factors were excluded. 42 patients who did not suffer from KOA who matched the age of patients in the KOA group were selected. The age, BMI, bone mineral density (BMD) and other data of the two groups of patients were collected. The correlation analysis between KOA and OP was conducted to determine the degree of correlation, so as to reveal the relationship between the incidence, progression, prognosis of KOA and OP.Results:BMD was correlated with BMI. BMD was negatively correlated with age. The incidence of KOA and OP was correlated with age. There is a large correlation between KOA and OP, and the probability of KOA associated with OP is high. For KOA patients, OP is less likely to be accompanied by a higher BMI, while OP is more likely to be accompanied by a lower BMI.Conclusions:OP is one of the pathogenic factors of KOA. KOA patients should be treated with anti-OP before and after surgery.

In addition, it explored the influence of problem stream, policy stream, and political stream on the policy launch process.These efforts can help improvement the policy awareness in the process, and help ensure sustainable progress of the policy.

The policy model of G. C. Edwards was used to study the policies on building a countywide medical community ( CMC), and identify problems in such aspects as policy communication, resources, disposition and bureaucratic structure. The analysis found that enriching health resources at primary level and powerful government support are creating ideal environment for the construction of CMC. But due to its preliminary development, rooms of improvement of its policy design, and unclear enforcement standards, there appear behavioral polarizations at local health authorities. For example, some are proactive to explore and accumulate rich experiences, while the most take a wait and see stand, or even take administrative means to cope with their authorities by forming medical communities in form only. A small part of county hospitals, thanks to support from the government and inherent conditions, take active measures in this direction as policy frontrunners. On the other hand, most county hospitals prefer to be policy followers in order to avoid cost and risks of the reform. In the worst cases, a few county hospitals have become free riders of the policy, and attempt to take advantages of their primary health institutions. Primary health institutions warmly embrace CMC, but their limited service capability constitutes roadblocks in CMC construction. What is more, poor communication and collaboration mechanisms among systems and authorities hinder the effective policy synergy and health service integration of CMS.

Objective To analyze the motives and tactics of township health centers ( THC) to participate in the countywide medical communities of Shandong province. Methods Such tools as the new institutionalism, rational choice and social network theories, as well as the constituent ratios and Pearson correlation coefficient of data were used in a survey in August 2018 with managers of 264 THCs in Shandong. It aimed to learn from the respondents their motives, tactics, and behaviors to participate in such communities. Results Theoretical analysis of the results found that their participation was bound by both institutional environment and technical environment. For example, compliance tactics, accompanied by efficiency, was adopted to cope with stress from institutional environment. Exploratory tactics, accompanied by legitimacy, was adopted to cope with stress from technical environment. The figures showed 87. 5％ of 264 THCs investigated participated in such communities, and their main motives were in turn to follow government requests (86. 1％ ) and to seek development opportunities (69. 7％ ). The critical criteria of partner selection were in turn technological level (83. 5％ ) and matching of resources (77. 9％ ). Of 231 THCs which participated in the communities, 95. 2％ joined in countywide medical communities, and 28. 6％ participated in other forms of medical alliances. Conclusions THCs showed high organizational convergence in their participation, and adopted diversified strategies of participation in medical alliance.
