The application of failure mode and effect analysis to improve the hand hygiene compliance of medical staff in eye hospital / 中华劳动卫生职业病杂志

Objective@#To discuss the application of failure mode and effect analysis to improve the hand hygiene compliance of medical staff in eye hospital.@*Methods@#To form failure mode and effect analysis (FMEA) quality control team. By using FMEA method of risk management, to analyze the risk factors of hand hygiene compliance of medical staff in eye hospital. By performing analysis, to determine the high risk factors, develop and implement the improvement measures to reduce the risk of these factors.@*Results@#the awareness rate of hand hygiene knowledge was increased significantly after the implementation of failure mode and effect analysis (P<0.01) , the correct rate of hand-washing method, and the implementing rate of 5 hand hygiene were increased significantly (P<0.05) . After the implementation of FMEA, the usage amount of hand washing liquid and quick hand disinfectant was increased from 13 292 ml to 28 390 ml, and difference of the hand hygiene qualification rate was statistically significant (P<0.05) .@*Conclusion@#The application of FMEA contributes to analyze the causes of hand hygiene failure, and guide the development of improvement measures, which can effectively improve the hand hygiene compliance of medical staff, thereby reducing nosocomial infection.

Advances in research on automatic exposure control of mammography system / 生物医学工程学杂志

Mammography imaging is one of the most demanding imaging modalities from the point of view of the bal- ance between image quality (the visibility of small size and/or low contrast structures) and dose (screening of many asymptomatic people). Therefore, since the introduction of the first dedicated mammographic units, many efforts have been directed to seek the best possible image quality while minimizing patient dose. The performance of auto- matic exposure control (AEC) is the manifestation of this demand. The theory of AEC includes exposure detection and optimization and also involves some accomplished methodology. This review presents the development and present situa- tion of spectrum optimization, detector evolution, and the way how to accomplish and evaluate AEC methods.

Analysis of related factors for osteoporosis in postmenopansal patients with type 2 diabetes mellitus / 中华老年医学杂志

Objective To investigate the morbidity and related factors for osteoporosis in postmenopausal patients with type 2 diabetes mellitus (T2DM).Methods The bone mineral density (BMD) at lumbar vertebrae(L1-4), left femoral neck, femoral trochanter and total hip were measured by dual energy X-ray absorptiometry (DEXA) in 79 postmenopansal patients with T2DM.The patients were divided into two groups: osteoporosis group and non-osteoporosis group.The correlations between BMD and age, course of disease, menopausal age, menopausal duration and body mass index (BMI) were analyzed by multivariate regression analysis.Results There were significantly statistical differences in age, BMI, interleukin 6 (IL-6), osteocalcin and menopause duration between two groups.Linear correlation analysis showed IL-6 was positively correlated with osteoporosis (r=0.260, P=0.020) and glycosylated hemoglobin (GHbAlc) (r=0.259, P=0.023) Logistic regression analysis showed that the morbidity of osteoporosis had an independent positive correlation with age, but an independent negative correlation with BMI.Conclusions In postmenopausal patients with T2DM, age and low BMI are independent risk factors for osteoporosis.
