【Abstract】Objective To investigate the contribution of occupational exposure to dusts / gases / fumes to chronic obstructive pulmonary disease( COPD) and respiratory symptoms in China. Methods Based on the crosssectional survey of COPD which was conducted in urban and rural areas of Beijing, Shanghai, Guangdong,Liaoning, Tianjin, Chongqing and Shanxi for residents aged 40 years or older, the association between the occupational exposure to dusts/ gases/ fumes and COPD and respiratory symptoms was analyzed. The recruited populations were interviewed with questionnaire and were tested with spirometry. The post-bronchodilators FEV1 /FVC lt; 70% was used as diagnostic criteria of COPD. Having any cough, sputum, wheezing and dyspnea was defined as having respiratory symptoms. Results The prevalence of occupational exposure to dusts/ gases /fumes was 20. 5% . As shown by multiple-variables Logistic regression analyses, occupational exposure to dusts / fumes /gases [ OR = 1. 20 ( 1. 04, 1. 39) ] and dusts of grain [ 1. 48 ( 1. 18, 1. 86) ] were associated with COPD;occupational exposure to dusts / fumes / gases [ OR = 1. 37( 1. 25, 1. 49) ] , hard-rock mining [ OR = 2. 31( 1. 67,3. 20) ] , coal mining [ OR = 1. 71( 1. 09, 2. 70) ] , dusts of cement [ OR = 1. 92( 1. 47, 2. 52) ] , chemical or plastics manufacturing [ OR =1. 58( 1. 37, 1. 83) ] , spray painting [ OR= 1. 46( 1. 16, 1. 84) ] , and other dusts or fumes [ OR = 1. 46 ( 1. 29, 1. 64 ) ] were associated with the respiratory symptoms. Smoking and occupational exposure to dusts / gases / fumes had synergic effects on the increasing risk of respiratory symptoms. The populationattributable risk ( PAR) of exposure to dusts / gases / fumes was 3. 94% and 7. 05% for COPD and respiratory symptoms respectively. Conclusions Occupational exposure to dusts /gases /fumes is associated with COPD and respiratory symptoms. Smoking and occupational exposure to dusts/ gases /fumes may have synergic effects on respiratory symptoms.
ObjectiveTo evaluate the influence of personalized nursing intervention on the negative emotions after occupational exposure for nurses in the Emergency Department, in order to provide effective nursing intervention methods for relieving nurses' negative emotions after occupational exposure. MethodsTwenty nurses with occupational exposure between January and September 2013 were chosen to be the control group, and another 20 nurses with occupational exposure between October 2013 and October 2014 were designated as the personalized nursing group. The level of depression and anxiety was compared between the two groups by using the self-rating depression scale (SDS) and self-rating anxiety scale (SAS) on the exposure day and 5 weeks after the exposure. ResultsBefore intervention, SDS score of the control group was 0.65±0.04 and of the personalized nursing group was 0.63±0.05, and there was no statistically significant difference between the two groups (t=0.59, P=0.44); SAS score of the control group was 51.98±6.77 and of the personalized nursing group was 50.73±10.03, and there was no statistically significant difference between the two groups (t=0.37, P=0.70). After the intervention, personalized nursing group had lower scores of SDS and SAS than the control group. SDS score was 0.64±0.11 in the control group and 0.50±0.09 in the personalized nursing group with a significant difference (t=5.11, P < 0.01); SAS score was 49.53±9.49 in the control group and 42.66±9.53 in the personalized nursing group, and the difference was statistically significant (t=4.10, P < 0.01). ConclusionThe personalized nursing intervention can effectively alleviate negative emotions after occupational exposure for nurses in the Emergency Department.
目的 了解医院内血源性职业暴露高风险人群，有针对性采取防护措施，降低血源性职业暴露的发生率。 方法 对2008年1月－2011年12月四川省妇幼保健院52例血源性职业暴露医务人员，按照暴露人群、暴露方式、暴露病种、暴露地点的不同进行调查分析。 结果 52例职业暴露人群中护士27例（占51.9%）；产房和手术室为高发职业暴露场所，共32例，分别为17例（占32.7%）和15例（占28.8%）；职业暴露病种主要为乙型肝炎，共27例（占51.9%）；暴露方式主要为针刺伤，共37例（占71.2%）。 结论 提高医务人员职业防护意识，规范操作流程，加强自身防护是减少职业暴露的根本所在。
ObjectiveTo evaluate the occupational exposures and protective condition of medical staff in operating room for interventional therapy. MethodsFrom September to November in 2014, 46 medical staff in the operating room for interventional therapy were adopted to complete the occupational exposures and protection situation survey. After that, we analyzed and scored all the questionnaires. ResultsThe awareness of the medical staff about occupational exposures and occupational protection in the operating room was low; the awareness rates of doctors, nurses, and radiology technicians were 74.2%, 63.0% and 66.7%, respectively. The general condition of implement of occupational protection measures of the medical staff was bad, and the average rate of the doctors, nurses and radiology technicians was 51.3%, 43.9%, and 15.2%. ConclusionThe implement rates of occupational protection measures of the medical staff in Operating Room for interventional therapy differ much from the awareness rates. The rates in doctors and nurses are higher than that in radiology technicians. We should strengthen the education of radiation damage and protection measures in doctors, and enhance the training of iatrogenic injuries related knowledge in clinical radiology technicians to reduce occupational hazards.
