Occupational exposure to bloodborne pathogens among health care workers / 中国感染控制杂志

Objective To investigate the characteristics and risk factors of occupationai exposure to bloodborne pathogens among health care workers (HCWs),and evaluate prevention and treatment countermeasures.Methods Record Form for Occupational Exposure to Bloodborne Pathogens Among Health Care Workers was used for retrospective survey on the occurrence of occupational exposure to bloodborne pathogens in a hospital between January 1,2013 and December 31,2015.Results A total of 246 cases of blood/body fluid occupational exposure occurred.The main occupational exposure population were nurses (n =95,38.62％);occupational exposure mainly occurred in wards(n =148,60.16％);the main mode of occupational exposure was sharp injury(n =219,89.02 ％);the main opportunity of occupational exposure of HCWs was surgical accident(n =69,28.05 ％);the main exposure source was hepatitis B virus(n =123,50.00 ％);none of HCWs developed infection after local treatment and prophylactic medication.Conclusion Medical institutions should strengthen the training for HCWs about occupational exposure to bloodborne pathogens,enhance protection awareness,standardize operation procedures,and improve working environment,so as to minimize the occurrence of occupational exposure.

Gastroscope Contamination:Status Investigation / 中华医院感染学杂志

OBJECTIVE To understand the status of gastroscope contamination.METHODS The bacterial(cultivation) of samples derived from inside and outside gastroscope after using was conducted.RESULTS There were heavy(contaminations) inside and(outside) gastroscope after using.Except for normal microbial populations(existing) on pharynx nasalis,many(conditional) pathogenic bacteria had been detected,such as Streptococcus pyogenes,Moraxella catarrhalis,and(nonzymocyte).CONCLUSIONS Many species of bacteria are detected inside and outside(gastroscope) after using.They are normal microbial populations in pharynx nasalis and some conditional pathogenic bacteria.It is (necessary) to strengthen regulation of gastroscope cleaning and disinfection. We should follow Technological Regulations of Disinfection(Ministry of Health,2004) to clean and disinfect endoscope strictly in order to avoid(hospital) acquired infection due to insufficient cleaning and disinfection.
