A total of 158 questionnaires were distributed and 150 valid questionnaires were completed. The effective questionnaire recovery rate was 94.9%. The mean score of basic knowledge of DVT was 6.45±1.83, the mean score of risk factors was 13.29±3.38, the mean score of intervention attitudes was 9.57±0.78, and the mean score of prevention implementation was 23.33±5.85.
Conclusions
The knowledge-practice of DVT intervention in orthopedic medical staff is moderate, and the attitude of DVT intervention is better among medical staff. There are various characteristics and weaknesses in knowledge-practice. It is necessary to regularly carry out knowledge about DVT among medical staff to improve the professional level of medical staff to prevent and treat DVT.
ObjectiveTo study the effect of new bundle interventions on medical staff’s cognition of occupational exposure protection and exposure rate, and provide evidence for reducing medical staff’s occupational exposure.MethodsThe 1 435 medical practitioners in 37 clinical/technical departments of Nanchong Central Hospital were selected as the research objects. Bundle intervention strategies about occupational exposure for whole population and high risk population were implemented, and the medical staff’s cognition of occupational exposure, occurrence of occupational exposure, and post-exposure reporting in 2017 (before intervention) and 2018 (after intervention) were investigated and compared to evaluate the intervention effects.ResultsThe numbers of valid survey forms collected before intervention and after intervention were 1 160 and 1 421, respectively. The total awareness rate increased from 91.10% before intervention to 96.10% after intervention (P<0.001). The exposure rate and average rank of exposure frequency after intervention were lower than those before intervention (10.98% vs. 17.50%, 1 250.74 vs. 1 340.32), the reporting rate of initial exposure after intervention (69.23%) was higher than that before intervention (57.64%), and the differences were all statistically significant (P<0.05).ConclusionThrough gradually implementing the new bundle interventions, medical staff can improve the cognition of occupational exposure, reduce the occurrence of occupational exposure, improve the enthusiasm of reporting, and create a safe atmosphere.

ObjectiveTo know the status and risk factors of occupational exposure in a top-class hospital in Sichuan, and provide the basis for occupational safety and protective measures.
Methods"Hospital Medical Staff Occupational Exposure Registration Form" was used in this retrospective study. Statistical analysis was performed on medical workers' exposure data between January 2011 and June 2014 in a top-class hospital in Sichuan Province.
ResultsA total of 139 cases of occupational exposures were recorded in some of the medical staff. There were more females than males. Nurses had the most exposures (70.5%), and the exposure sources were mainly human immunodeficiency virus and hepatitis B virus (27.9% and 21.0%, respectively). The exposure type was mainly sharp injury (84.2%). Exposure occurred mainly in surgery (47.5%), and different job or places had different exposure types with significant differences (χ2=12.683, 20.897, P<0.05). Sharp injury was mainly caused by the scalp needle and syringe, and the injured sites were mainly upper limbs (98.3%). However, exposure to blood and body fluids occurred mainly on upper limbs (54.5%) or face (45.5%).
ConclusionOccupational exposures are mainly sharp injuries, especially in surgeries. Women, nurses or medical staff with low qualifications had the highest exposure risk. Thus, occupational safety and protection training should be strengthened.

ObjectiveTo investigate the network structure of comorbid depression and anxiety symptoms among medical staff and analyze differences across institutional types. MethodsA convenience sampling method was used to select medical staff from medical institutions at various levels in Guang'an City as participants between August 10 and 15, 2024. General demographic questionnaires, the Chinese version of the Patient Health Questionnaire (PHQ-9) for depression screening, and the Chinese version of the Generalized Anxiety Disorder Scale (GAD-7) were used to survey them. The study aimed to analyze the influencing factors of anxiety and depression and construct a network model. Predictability, bridging strength, and node strength were used to assess the network structure. The non-parametric bootstrap method was employed to evaluate the accuracy and stability of the network, and finally, a Network Comparison Test (NCT) was used to examine the impact of different levels of healthcare institutions on the network model. ResultsA total of 889 participants were included in the study. The analysis showed that the incidence of depressive symptoms (PHQ-9≥5) among healthcare workers was 44.88%, while the incidence of anxiety symptoms (GAD-7≥5) was 43.98%, with a comorbidity rate of 36.67%. Network analysis revealed that the top three symptoms with the highest node strength were difficulty relaxing (A4), excessive worry (A3), and fatigue (D4). The top three symptoms with the highest bridging strength were irritability/anger (A6), fatigue (D4), and worrying about terrible things happening (A7). The different levels of healthcare institutions did not have a significant impact on the network model. ConclusionThe central symptoms (such as difficulty relaxing, excessive worry, and fatigue) and key bridging symptoms (such as irritability/anger, fatigue, and worrying about terrible things happening) in the anxiety and depression symptom network can serve as potential intervention targets for healthcare workers at risk of depressive and anxiety symptoms.
Objective To examine the prevalence of post-traumatic stress disorder (PTSD), anxiety, and depression for medical staffs who took part in rescue in the disaster area after Wenchuan Earthquake. Methods According to purpose sampling method, from June 12th to June 18th, we investigated the medical staffs in eight areas, and the total number was 500. The eight areas included Mianzhu, Deyang, Shifang, Chengdu, Mianyang, Pengzhou, Zitong, and Anxian. The survey tools were PTSD Checklist-Civilian Version (PCL-C), Self-Rating Anxiety Scale (SAS), and Self-Rating Depression Scale (SDS). After collecting all questionnaires, we divided 500 medical staffs into 2 groups, according to the fact whether the rescue was carried out in the disaster area or not. Results A total of 500 questionnaires were given to the subjects, of which 481 effective ones were collected, and the effective rate was about 96.2%. In addition, the prevalence of PTSD for overall was 23.3%, anxiety was 21.6%, depression was 49.9%, and the anxiety plus depression was 19.54%. At the same time, we found out the averages of PCL-C (48.29±29.90 vs. 34.76±18.03), PCL-C frequency (16.27±15.14 vs. 9.99±10.25), PCL-C severity (32.03±15.26 vs. 24.85±8.60), SAS primitive (37.39±10.35 vs. 32.22±7.61), SAS standard (46.73±12.94 vs. 40.27±9.51), SDS primitive (42.00±8.32 vs. 37.99±9.63), and SDS standard (52.50±10.39 vs. 47.48±11.92) were different. The medical staffs in the disaster area were under more severe conditions, and there were significant differences between the 2 groups. The prevalence of PTSD (28.52% vs. 16.59), anxiety (28.89% vs. 12.32%), depression (58.15% vs. 39.34%), and anxiety plus depression (26.67% vs. 10.43%) between the 2 groups was significantly different, and the disaster area was under severe conditions. Additionally, the prevalences at three levels within SAS and SDS were much higher in the disaster area. There were also significant differences. Conclusion The prevalences of PTSD, SAS, and SDS within medical staffs who took part in rescue in the disaster area after Wenchuan Earthquake are higher than in the non-disaster area. Therefore, we should work out mental intervention and rehabilitation project for medical staffs, especially those who took part in rescue in the disaster area. Finally, the medical staffs’ ability to copy with stress can be improved.
ObjectiveTo investigate the knowledge and attitude of medical professionals in various regions of China on obstructive sleep apnea (OSA) and to find out the influence of sleep center setting on the above results.MethodsA self-designed questionnaire based on OSAKA questionnaire was designed. A total of 630 medical staff were investigated in 7 hospitals at different levels in various regions in China. The subjects were divided into two groups according to whether they had sleep center (including sleep monitoring room) or not. Survey data were analyzed.ResultsA total of 630 questionnaires were sent out, and 590 valid questionnaires were received, and the effective response rate was 93.65%. About half of those surveyed had sleep centers in the hospitals where they worked. There was no significant difference in three attitude problems and the choice of continuous positive airway pressure and surgical treatment between the two groups (all P>0.05). Subjects whose hospital had no sleep center were more prone to select weight loss (estimated parameters=0.513, P=0.046), no smoking and wine (estimated parameter=0.472, P=0.040), avoidance of overwork (estimated parameter=0.933, P=0.000), and drug (estimated parameter=0.802, P=0.000). The average correct rate of OSA knowledge was 45.59%±20.68%. Among them, the correct rate of response to treatment measures was the highest, and the correct rate of other knowledge points was poor. The average correct rate of total accuracy, symptoms and target organ damage in subjects whose hospital had sleep center was higher than that in subjects whose hospital had no sleep center, and there were significant differences (P=0.001, P=0.012, P=0.000). There was a positive correlation between the knowledge of OSA and their attitude towards OSA, treatment and further understanding of the knowledge (r=0.247, P=0.000).ConclusionIt is necessary to strengthen propaganda and education of OSA, and the establishment of sleep center is helpful for medical personnel to know more about OSA and to develop sleep medicine.
ObjectiveTo develop the questionnaire and test its reliability for investigating route, prevention, and control of SARS-CoV-2 infection in medical staffs.MethodsThis questionnaire was development based on the COVID-19 relevant guidelines, official documents issued by the National Health Committee of the People's Republic of China, and published studies. The development group performed repeated discussions and drafted the first questionnaire, then performed expert consultation and revised the draft according to their suggestions. Eventually, some frontline medical staffs were invited to carry out pre-test investigation of the questionnaire and test its reliability.ResultsThe first draft included 48 items; 18 experts were invited in the first round questionnaire and 10 experts in the second round questionnaire. The positive coefficient of experts in these two rounds was both greater than 75%, and the authority coefficient of experts' opinions was greater than 0.70. The variation coefficient of these items was between 0.00 and 0.35, the coordination coefficient of experts was 0.193 (P<0.05). The experts of above two rounds put forward 14 suggestions for text modification or adjustment options of some items; after the development group held repeatedly discussions, a total of 8 items were performed secondary consultation and finally reached consensus. The final questionnaire included two domains of questionnaire before and after confirmed diagnosis. The domain "before confirmed diagnosis" covered 4 sections and 29 items involving infectious cause, plan and knowledge of prevention and control, and psychological symptoms. The domain "after confirmed diagnosis" covered 5 sections and 21 items, included symptoms, treatment, and psychological status after diagnosis; impact on the surrounding environment and people, and awareness of protection after infection. The pre-test results showed that the total items were considerably numerous, some items were difficult to understand, some laboratory results and treatment conditions were ambiguous, etc. After modification and re-testing, the test-re-test reliability of each domain was between 0.74 and 0.93, and the overall re-test reliability of the questionnaire content was 0.82.ConclusionsThis research has developed a questionnaire for investigating infection process, prevention and control of SARS-CoV-2 infection in medical staff, and the items considered two domains prior to and after confirmed diagnosis. The reliability and practicability of the questionnaire are acceptable.
Objective To investigate the free influenza vaccination of health care workers in major departments and explore the possible influencing factors of influenza vaccination of staff. Methods In November 2021, a questionnaire survey was conducted among health care workers who received free influenza vaccination in 19 major departments of West China Hospital of Sichuan University, and the un-vaccinated workers’ information was obtained from the registration system of staff information. Multiple logistic regression model was used to analyze the possible influencing factors of free influenza vaccination. Results The coverage rate of centralized free influenza vaccination of staff in major departments was 32.7% (1101/3369). Multiple logistic regression analysis showed that workers who were female [odds ratio (OR)=1.853, 95% confidence interval (CI) (1.481, 2.318), P<0.001], with an educational background of high school or below [OR=4.304, 95%CI (2.484, 7.455), P<0.001], engaged in nursing work [OR=2.341, 95%CI (1.701, 3.221), P<0.001], and with 11 or more years of working experience [OR=2.410, 95%CI (1.657, 3.505), P<0.001] were more likely to inject influenza vaccine, and workers who had a bachelor’s degree were less likely to inject influenza vaccine. Conclusions The rate of free influenza vaccination among medical staff is low. In order to mobilize the enthusiasm of influenza vaccination among medical staff, it is necessary to analyze the characteristics of the population and take targeted measures to improve the level of vaccination among medical staff.
