Objective To understand the occupational exposure among medical laboratorians in a hospital,and put forward prevention and control measures.Methods Occupational exposure among medical laboratorians in the department of laboratory medicine of a hospital from January 2011 to December 2014 were analyzed statistically.Results A total of 72 cases of occupational exposure occurred among 217 laboratorians during 4 years,occupational exposure rate was 33.18％,the occupational exposure rate in interns was 46.23％,and in laboratorians with working seniority＜ 1 years was 49.56％.Occupational exposure mainly occurred in outpatient blood collection room(accounting for 38.89 ％),the main occupational exposure types were injuries by blood collection needles,skin contaminated by blood and body fluid(76.39 ％).Occupational exposure rates in medical laboratorians in this hospital during 2011-2014 were 53.66％(22/41),41.67％(20/48),26.23％(16/61),and 20.90％(14/67),respectively,which presented a declining tendency(x2 =12.286,P＜0.01).After occupational exposure,only 23 cases were reported according to the requirements of infection management department,the missing report rate was 68.06％ (49/72),correct handling rate was 80.56％ (58/72).Conclusion Laboratorians should strengthen education and training of healthcare-associated infection management,improve safety and prevention consciousness,standardize handling process,improve consciousness of reporting,so as to reduce the occurrence of occupational exposure and post exposure infection.

Objective To provide reference for CT performance/quality test. Methods Researches were made in Chinese documentations on CT performance/quality test issued from 1998-aug 2002.Results Approximately a quarter of CTs among the documents assembly released public were tested unqualified . Qualification rate of new CTs was higher Than second-handed ones. Part of items and data in the documentations were insufficient. Conclusion CT performance/quality test is a crucial part of system Engineering of QC(quality control),therefore it must be implemented seriously and relevant regulations should be optimized in order to benefit both patients and health-care communities.
