RESUMO
Objective To scientifically assess the degree of " overwork" and its influencing factors of doctors and nurses at county hospitals. Methods Six county hospitals were selected as the research objects. Descriptive analysis, chi-square test and ordered multi-class regression were used to analyze the degree of " overwork" and its influencing factors of doctors and nurses. Results 48. 3％ (156 / 323)of the doctors at these hospitals were working more than 60 hours per week. Work hours per week of the doctors were significantly longer than those of the nurses. At the same time, the workload of doctors based on the fatigue self-assessment scale was also significantly higher than that of the nurses, while 61. 9％ (200 / 323) of the doctors were exposed to a very high workload, and so were 33. 3％ (118 / 354) of the nurses. There were significant differences in the workload of doctors and nurses in terms of their gender, age, education level, seniority and number of children. And the work hours per week were an important factor affecting the workload of doctors and nurses. Conclusions We should formulate a reasonable work hours for doctors and nurses, especially focusing on young and middle-aged doctors.
RESUMO
Objective To investigate the current condition and risk factors of Keshan disease (KD) in Shandong Province,and to provide a scientific basis for prevention and control of KD.Methods Based on the 2014 scheme of KD surveillance,residents in 38 surveillance sites of 19 counties (cities,districts) were surveyed by questionnaire survey,physical examination,electrocardiograms (ECG),X-ray or echocardiography.At the same time,some residents' hair,grain and soil samples were collected,and the content of selenium in the internal and extemal environment was tested.KD was evaluated in Shandong Province based on the "National Standard of Evaluation Method for Key Endemic Disease Control and Elimination".Results ①In 38 monitoring sites,16 168 residents were surveyed and 164 cases of KD were detected (in which 149 cases of potential,15 cases of chronic),the detection rate was 1.014％.② Totally 2 497 samples of hair (n =763),food (wheat:n =687,corn:n =751) and soil (n =296) were collected and the selenium contents in hair was (0.379 ± 0.120) mg/kg,in wheat and corn were (0.025 ± 0.009) mg/kg and (0.016 ± 0.007) mg/kg,and in soil was (0.132 ± 0.046) mg/kg.③According to the national standard of evaluation content and decision criteria for KD,6 counties achieved the elimination index and 13 counties were in the control level in Shandong Province,the county proportion of eliminating KD was 31.58％ (6/19).Conclusions ①The current condition of KD in Shandong Province remains relatively stable.Internal environment selenium content is increased significantly due to improvement of people's living standard and dietary nutrition.②There is still a gap between the number of counties eliminated KD and the "elimination targets" required by the state in Shandong Province.It is recommended to continue to strengthen the team construction in prevention and control of KD and to enhance the investment of money,at the same time,to establish a long-term working mechanism in prevention and control of KD.
