ObjectiveTo analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province. MethodsThis is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors. ResultsAmong 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes (P＜0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 (P＜0.05). Compared with those with visual acuity＜0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity≥0.1 was significantly decreased (P＜0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate (P＜0.05). ConclusionsThe DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.
ObjectiveTo explore the effect of case-based learning combined with scenario exercise on nosocomial infection prevention and control training.MethodsClinical nursing students who entered the Department of Western & Traditional Chinese Medicine between September 2018 and November 2019 were selected. These students entered in groups. According to the entry number, the groups were divided into trial group and control group by odd or even numbers. The two groups of nursing students were trained by the infection prevention and control nursing group of the department to prevent nosocomial infection on the first day of entering the department. The trial group adopted case-based learning combined with scenario exercise, while the control group adopted traditional lecture-based learning. The two groups were compared by hand hygiene compliance rate, hand hygiene accuracy rate, clinical waste classification and disposal accuracy rate, occupational exposure, nosocomial infection prevention and control assessment scores, and teaching method satisfaction.ResultsA total of 63 nursing students from 10 groups were enrolled. There were 32 students from 5 groups in the control group and 31 students from 5 groups in the trial group. The hand hygiene compliance rate (χ2=8.434, P=0.004), clinical waste classification and disposal accuracy rate (χ2=4.196, P=0.041), nosocomial infection prevention and control assessment scores (t=3.145, P=0.003) and satisfaction scores of teaching methods (t=2.446, P=0.017) in the trial group were all higher than those in the control group. There was no occupational exposure in the trial group, but 1 case in the control group. The correct hand hygiene rates of the two groups were both 100%.ConclusionCase-based learning combined with scenario exercise can effectively improve the awareness of nosocomial infection prevention and control, improve the knowledge and skills of nosocomial infection prevention and control, improve the effectiveness of nosocomial infection prevention and control training, and increase the satisfaction of clinical teaching.
Objective To provide baseline data for the Special Healthcare Program of Comprehensive Reform for Coordinated and Balanced Urban-rural Development in Chengdu. Methods We selected 7 township/community health institutions and 6 village health posts /street clinics using stratified sampling to take account of the levels of economic development and the distance from the centre of Chengdu We then performed on-site surveys and secondary research. Data were analyzed by using Epidata or Excel. Results The utilization of health institutions was generally good. The number of visits and number of inpatients in medical institutions increased steadily. The utilization rate of hospital beds and doctors’ workload were higher than the national average. The average medical expense per outpatient /inpatient was far lower than the national level. The overall condition of the health institutions that close to the centre of Chengdu was better. Conclusion We should persist in taking advantage of the rural hospitals’ construction to improve village health posts /street clinics and strengthen the national and governmental compensating mechanism for township /community health organizations (village health posts /street clinics), so as to make the basic condition of current township/ community health organizations (village health posts /street clinics) better.
ObjectiveTo optimize procedures of going out for examination for patients with multidrug-resistant organism, strengthen prevention and control management of nosocomial infection, and prevent nosocomial infection.MethodsPatients with multidrug-resistant organism who went out for examination were selected from April to November 2018. April to July 2018 (before implementation) was process construction stage, and August to November 2018 (after implementation) was process optimization implementation stage. In April 2018, process and management system of going out for multidrug-resistant organism patients were formulated, training of transporters was strengthened, and measures such as checklist identification, accompany patients for examination, patient handover, isolation and protection, and disinfection of materials were implemented, to realize the infection prevention and control management in the whole process of going out for multidrug-resistant organism patients. We compared relevant indicators before and after implementation.ResultsA total of 262 cases times of patients with multidrug-resistant organism were included, including 134 cases times before implementation and 128 cases times after implementation. Compared with before implementation, the hand hygiene, wearing gloves, disinfection of inspection instruments and articles, patient transfer, isolation measures in waiting process (special elevator, isolation after waiting for inspection, arrange inspection time reasonably), education and training after implementation improved(P<0.05). Before and after implementation, the Methicillin resistant staphylococcus aureus detection rate difference was statistically significant (P<0.05).ConclusionsThe optimization of procedures of examination for patients with multidrug-resistant organism can increase implementation rate of indirect indicators such as hand hygiene, disinfection of inspection instruments and articles, isolation and protection, education and training in the prevention and control of multidrug-resistant organism in nosocomial infection. And it is important for the prevention and control of multi-disciplinary collaboration of multidrug-resistant organism.
Objectives To analyze the effect of improved oven for defluorination in coal-burning endemic fluorosis areas in China, and to provide evidence for the prevention and control of fluorosis. Methods Electronic databases including CNKI, CBM, VIP and CDMD-D (1989 to 2005), were searched. We also checked the reference lists of relevant articles. We selected relevant articles according to the predefined inclusion and exclusion criteria. The methodological quality was assessed . Data on room heat preservation and the effect of improved oven for defluorination were collected in the surveillance spots of Three Gorges Reservoir. Correlation analyses were conducted between the improved oven and its effect parameters. Results Twelve articles of low quality met the selection criteria, of which 9 were graded C and 3 were graded D in terms of the methodological quality. A negative correlation was found between the decreasing rate of normal oven use and the decreasing rate of dental fluorosis as well as of urine fluorine (Pearson correlation coefficient r = – 0.87, – 0.63, Plt;0.01, lt;0.05, respectively). Analysis also revealed a positive correlation between room heat preservation and the decreasing rate of dental fluorosis as well as of normal oven use (the two Spearman correlation coefficients and P values were the same: r = –1.00, Plt;0.01). Conclusion High-quality studies on the effect of improved oven for defluorination in China are not available. Based on the current evidence, the improved oven for defluorination and the correct use, maintenance and house rebuilding for heat preservation may help to prevent fluorosis.
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.
ObjectiveTo learn the status quo and characteristics of multi-drug resistant organism (MDRO) infection in a comprehensive hospital of the first grade in Sichuan Province, analyze the effect of prevention and control intervention, in order to provide a scientific basis for clinical MDRO prevention and control. MethodsWe collected MDRO data from January to June 2014 and from January to June 2015 through multi-drug resistance reporting software, and analyzed and compared the infection of MDRO during those two time periods. Then, we evaluated the prevention and control effect of MDRO infection. ResultsThe number of inpatients from January to June 2014 was 24709, among which 813 were detected with MDRO infection. Of those infected patients, 196 had nosocomial infection of MDRO and the other 617 had community infection/colonization. The proportion of nosocomial MDRO infection was 24.10%. The MDRO nosocomial infection case rate was 0.79%. The proportion of community MDRO infection/colonization was 75.90%. The number of inpatients from January to June 2015 was 25329, and 739 of them were found with MDRO infection, of whom 132 had nosocomial infection and 607 community infection/colonization. The proportion of nosocomial MDRO infection was 17.86%. The MDRO nosocomial infection case rate was 0.52%. The proportion of community infection/colonization was 80.14%. Compared with the first half of 2014, the proportion of nosocomial MDRO infection was lower with a statistically significant difference (χ2=9.062, P<0.001), and MDRO nosocomial infection case rate was also significantly lowered (χ2=14.220, P<0.001). There were significant differences between the first half of 2015 and the same period of 2014 in hospital department distribution of MDRO infection, patient infection site distribution and pathogen detection. ConclusionThe nosocomial MDRO infection control situation of our hospital is improved after the comprehensive prevention and control interventions, and we should focus on the prevention and control of key departments, important infection sites and major resistant bacteria in the future MDRO hospital infection control work.

Due to the high incidence and the earlier onset age, high myopia has become an important public health problem in China. Posterior scleral reinforcement surgery has been developed for over 60 years in order to control the rapid progression and complications of high myopia. By suturing a certain size of material on the surface of the posterior eyeball, thickness and elasticity modulus of the local sclera significantly increase. As the result, the rapid growth of the axial length and the chorioretinopathy could be alleviated. At present, controversies about its clinical efficacy and safety still exist, so posterior scleral reinforcement surgery has not been widely carried out all over the world. An in-depth analysis of the mechanism, surgical manipulations and materials, the clinical application status of posterior scleral reinforcement surgery on control of high myopia can provide a basis for further standardized application of this surgery
