ObjectiveTo analyze the risk factors for hospital infection in the medical physical examination center of a newly opened hospital, and to explore its prevention and control measures. MethodsBetween April and December 2012, we analyzed the risk factors for hospital infection in the physical examination center of a new hospital. A series of hospital infection prevention and control measures such as carrying out education and training of medical personnel, strengthening the prevention of needle stick injuries, implementing strict disinfection and sterilization, improving environmental hygiene, and implementing medical waste management, were developed. ResultsMedical staff's knowledge of disinfection and sterilization was improved; hand hygiene compliance was increased; hospital environmental hygiene was promoted, and medical waste was properly sorted out. ConclusionTaking reasonable measures for infection prevention and control can increase medical staff's awareness of hospital infection prevention and control, improve their practices of infection control and prevent hospital infections from occurring eventually.
ObjectiveTo explore the plan-do-check-action (PDCA) circulation method in reducing errors in general inspection items of health examination and to improve the quality of examination. MethodsUsing PDCA circulation method, the reasons of errors in general items of health examination for 39 individuals examinied between August and December 2010 were analyzed. Rectification was carried out according to the reasons, and the differences in the incidence rate of errors in general items of health examination before (from August to December, 2010) and after the rectification was (from Auguest to December, 2011) was compared. ResultsAfter the rectification, the incidence of errors in general items of health examination (0.08%) was significantly lower than that before the rectification (0.45%) (P<0.05). ConclusionPDCA circulation method can effectively reduce the incidence of errors in general items of health examination thus may ensure the medical quality.
Objective To explore the correlation between metabolic syndrome and renal function in physical examination population. Methods The data of individual physical examination in West China Hospital from March to April 2015 was collected. Body mass index (BMI), glomerular filtration rate (GFR) were calculated, and the correlation between metabolic syndrome and renal function was analyzed by using SPSS 16.0 software. Results A total of 10 098 individuals were included, of which 1 110 were MS patients were included. The results of analysis showed that, the levels of uric acid, cholesterol, urea and creatinine in MS group were significantly higher than those in non-MS group, and the level of GFR was significantly lower than that in non-MS group (P < 0.05). Renal function in patients with abnormal systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), low density lipoprotein, total cholesterol, triglycerides, uric acid index were significantly higher than those in normal renal function group, and high density lipoprotein cholesterol was significantly lower than that of normal renal function group (P < 0.01). Conclusion Elevated levels of BMI, blood pressure, glucose, uric acid are correlated with the decrease of GFR, and metabolic syndrome is an important risk factor of renal dysfunction.
Objective To investigate and analyze the 3-year physical examination results of the employees of a large financial enterprise in Chengdu, explore the key factors of health management and provide scientific basis for implementing reasonable health management. Methods The physical examination results of the employees of a large financial enterprise in Chengdu from 2012 to 2014 were analyzed, and the common abnormal results in the physical examination were summarized. Results The proportion of the employees whose physical examination results were completely normal in 2012, 2013, and 2014 was 4.97%, 2.01%, and 1.48%, respectively, showing a decreasing trend. Overweight, fatty liver and elevated triglycerides were always the top three of the abnormal examination results; the detection rates of which in the male staff were much higher than those in the female staff (P<0.05). In the female staff, the detection rate of overweight was always in the first place; the detection rate of columnar ectopy was always in the top three; the detection rate of liver cyst was in third place in 2013; and the detection rate of Nabothian cyst was in the second place in 2014. Conclusion The health management program of employees of this large financial enterprise is poor, thus health management should be paid enough attention to improve the employees’ physical quality.
ObjectivesTo investigate the level of ankle-brachial index (ABI) of health examination population in Chongqing municipality and analyze the risk factors related to the level of ABI, so as to provide basis for effective evaluation of atherosclerotic lesions and their severity, as well as early detection, intervention and treatment of clinical cardiovascular diseases. MethodsA total of 22 886 subjects aged from 20 to 85 undergoing health examination in the medical examination center of First Affiliated Hospital of Chongqing Medical University in Chongqing municipality from January to December in 2016 were retrospectively analyzed. ABI and related physiological and biochemical data were collected. The relationship between ABI and age was analyzed using stepwise logistic regression model combined with restricted cubic splines. ResultsThe detection rate of abnormal ABI was 3.31% in 22 886 subjects undergoing health examination with 2.90% in males and 3.92% in females. The subjects aged below 40 presented the highest detection rate of abnormal ABI (6.17%) with 4.72% in males and 8.66% in females. The subjects were divided into two groups, one with ABI≤0.9 and one with ABI>0.9; the differences in age and levels of body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) between the two groups were statistically significant (allP<0.05). Multivariate stepwise logistic regression combined with restricted cubic splines showed that age, gender and BMI were presented as independent factors affecting ABI, among which the age below 40 (OR=2.885, 95%CI (2.445, 3.404),P<0.0001) was the main risk factor. A curve relating age to probability of abnormal ABI was produced after correcting for the influences of sex and BMI, stratified by gender and BMI into different subgroups, showing a U-shaped curve of decreasing initially and then increasing between the probability of abnormal ABI and age. ConclusionsThe detection rate of abnormal ABI based on individuals undergoing health examination in Chongqing municipality was 3.31%. A U-shaped curve of downward trend followed by an upward one was shown between probability of abnormal ABI and age after correcting for the influences of gender and BMI. The clinical significance of ABI≤0.9 for youth population (20 to 40 years old) without cardiovascular risk factors requires further exploration.
Objective Using molecular biology method to detect and genotype human papilloma virus (HPV) in women taking physical examination in West China Hospital, Sichuan University, to explore the infection status and genotype distribution of HPV in normal women in Chengdu area, and to provide basis for early effective prevention and control of cervical cancer and domestic research and development of HPV vaccine. Methods Flow fluorescent hybridization technique was used to detect and genotype HPV-DNA in 25 148 healthy women taking physical examination in West China Hospital, Sichuan University between May 1st, 2018 and May 31st, 2019. The overall positive HPV infection rate, HPV genotype distribution, and characteristics of HPV infections were analyzed and calculated, and the HPV infection rates of different age groups were calculated and compared by chi-square test using SPSS 17.0 software. Results The overall positive rate of HPV infection was 12.19% (3 066/25 148). The high-risk HPV genotypes infection rate was 8.69% (2 186/25 148), and the top five subtypes with the highest infection rates were HPV52, HPV53, HPV58, HPV16, and HPV39. The low-risk HPV genotypes infection rate was 4.66% (1 171/25 148), and the top five subtypes with the highest infection rates were HPV61, HPV81, HPV43, HPV44, and HPV6. Single subtype infections were the main infections with a proportion of 81.74% (2 506/3 066), and the most common multiple infections were double infections which accounted for 13.96% (428/3 066). In different age groups, the HPV infection rate of group 60-69 was the highest (12.87%), while that of group 70-89 was the lowest (10.88%), but the difference among different age groups was not statistically significant (χ2=4.035, P=0.544). Conclusion According to the results of this study in women taking physical examination in West China Hospital, Sichuan University, we suggest adding HPV52, HPV53, and HPV58 which have the highest infection rate in high-risk HPV subtypes to the evaluation of domestic HPV vaccine screening and the cervical cancer prevention and control system.
