ABSTRACT
Objective To study the characteristics of occupational exposure to blood-borne pathogens and the cost of prevention and control,and provide evidence for policy making in medical institutions.Methods A prospective study was conducted to collect the data and follow-up data about occupational exposure of health care workers(HC-Ws)from the occupational exposure reporting system of a hospital between June 1,2016 and May 30,2017.Results There were 95 cases of occupational exposure to blood-borne pathogens.Occupational exposure occurred mainly in June,July,and November,peak time for occurrence was 12∶00 at noon.The main occupations of HCWs who sustained occupational exposure were nurses (41.05%),doctors (28.42%),and practice nurses (15.79%).The main departments of occupational exposure were central operating room (21.05%), emergency department (1 1.58%),and interventional radiology department (6.32%).The total cost of prevention and control for 95 times of occupational exposures were 33 235.20 Yuan,with an average of 349.84 Yuan per case.The average cost per case after human immunodeficiency virus (HIV)exposure was the highest (2 787.50 Yuan);and cost of syphilis exposure was the lowest (58.88 Yuan).Conclusion It is necessary to strengthen the training and education of high-risk time,high-risk population,and high-risk departments of occupational exposure to blood-borne pathogens,pre-vention of occupational exposure with high cost of prevention and control such as HIV should be especially paid attention.
ABSTRACT
We designed two types of pre-adaption plans for this study. One was a pre-adaption training with progressive intermittent hypoxia, with a constant lower pressure oxygen tank used in the plain before arriving at the plateau (PG). The other was by progressively increasing the time of exposure to hypoxia with oxygen supplied in stages after radical plateau (RG). By testing the blood oxygen saturation (SpO2), heart rate (HR), and quality of sleep after arriving at the 3800 m high plateau, results showed that the pre-acclimatization and radical groups performed better than the control group (CG). Both strategies were equivalent in terms of effects and principles in providing more flexible choices for acclimatization.
