RESUMO
Objective @#To investigate the occupational exposure to blood-borne pathogens among medical workers in a tertiary general hospital in Hangzhou City from 2010 to 2022, so as to provide the evidence for improving occupational protective measures among medical workers.@*Methods@#The registration and follow-up data of occupational exposure to blood-borne pathogens among medical workers from 2010 to 2022 were collected from the blood-borne occupational exposure monitoring system in a tertiary general hospital in Hangzhou City. The population distribution, occurrence, protection and disposal of occupational exposure to blood-borne pathogens were analyzed using a descriptive epidemiological method.@*Results@#A total of 1 230 cases were reported with occupational exposure to blood-borne pathogens among medical workers in the study hospital from 2010 to 2022, with the highest incidence in 2021 (4.67%) and the lowest incidence in 2010 (0.99%). The incidence of occupational exposure to blood-borne pathogens appeared a tendency forwards a rise from 2010 to 2022 (P<0.05). Of all cases with occupational exposure to blood-borne pathogens, there were 934 women (75.93%), 656 nurses (53.33%), and 514 cases with working experiences of one year and shorter (41.79%). Hand was the predominant site of occupational exposure to blood-borne pathogens (92.03%) and ward was the predominant place of exposure (35.37%), while scalp needle was the predominant mode of exposure (32.68%), and removal of needle was the predominant procedure of exposure (32.36%). A total of 1 106 cases were tested for the blood-borne pathogens in the exposure sources, and 448 cases were tested positive for blood-borne pathogens, with a detection rate of 40.51%. Hepatitis B virus, treponema pallidum and human immunodeficiency virus were the three most common blood-borne pathogens, and there were 739 cases (60.08%) with personal protective equipment during exposure. Following the follow-up surveillance for more than 6 months post-exposure, no infections occurred. @*Conclusions@#Junior nurses and hand exposure were predominant among medical workers with occupational exposure to blood-borne pathogens in the study hospital from 2010 to 2022, and hepatitis B virus was the predominant blood-borne pathogen. No post-exposure infections occurred.
RESUMO
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.
RESUMO
Objective:To probe into the status characteristics and the dynamic change trend of the psychological stress among medical staff at four time points after exposed to blood-borne pathogen.Methods:A longitudinal study was carried out among 78 medical personnel in this study,with 67 of hepatitis B virus,5 of hepatitis C virus,4 of HIV and 2 of treponema pallidum respectively.Perceived stress scale (PSS-4),Post-traumatic stress disorder Checklist-5 (PCL-5),Hospital anxiety and depression scale (HADS) were used to assess the psychological status,including perceived stress,post-traumatic stress symptom,anxiety and depression at the four times.Data analysis was performed using repeated measures analysis of variance (RMANOVA) and paired sample t test to explore time effect of the psychological stress reaction in the exposed population.Results:The scores of PSS-4,PCL-5,HADS-A,and HADS-D increased from exposure,and gained highest at one month after exposed,then gradually declined with time (Ps ＜ 0.05).Conclusion:It suggests that the levels of perceived stress,post-traumatic stress symptom,anxiety,depression may be the highest at one month after exposed.
RESUMO
Pesquisa descritiva, quantitativa, que se propôs a levantar a frequência de acidentes ocupacionais, envolvendomateriais biológicos potencialmente contaminados, que ocorreram entre os profissionais que atuam em um hospital deensino e caracterizar aqueles que acometeram a equipe de higienização e limpeza e lavanderia. Foram analisadas 238 fichasde investigações de acidentes de trabalho do Serviço de Epidemiologia do período de 2004 a 2009. Destas, 10,9% (26/239)correspondiam a acidentes ocorridos com profissionais da limpeza hospitalar, 2,5% de profissionais da lavanderia. Foipredominante o sexo feminino, faixa etária de 30-40 anos, do tipo percutâneo, destacando-se os quirodáctilos como a áreacorporal mais atingida e o líquido potencialmente contaminado foi o sangue. Três grandes pilares de assistência devem serfortalecidos: o sistema de informação para subsidiar a política institucional, a formação continuada dos profissionais quegeram resíduos perfurantes e a aquisição de materiais com dispositivos de segurança.
This is a descriptive and quantitative research which aimed to study the annual frequency of workplaceaccidents that occurred among health professionals and to characterize the occurrence of work acidentes involvinghospital hygiene staff. 238 professional accidents? reports were analyzed, from the Epidemiology Department in an UniversityHospital, from 2004-2009. From the total, 10,9% (26/238) corresponded to accidents with hygiene staff , and 2,5% with theones who worked at the laundry service. Data were gathered from the form of Surveillance System PSBio. It was observedthat there was a greater frequency of accidents, especially among the female workers, aged from 30-40 years, withpredominance of percutaneous exposure, especially the fingers as the most affected part of the body. Three pillars ofassistance should be strengthened: the information system to support the institutional policy, continuing education ofprofessionals who generate perforating residues and purchase of materials with safety devices.
