一篇连续现患率调查论文
Successive point-prevalence surveys were conducted annually from 2007to 2011 to monitor the prevalence of healthcare-associated infections (HAIs) in auniversity hospital in Hubei Province in China. The surveys used the case definitioncriteria established by the Ministry of Health of the People’s Republic of China. Inthe 5 surveys, the overall frequency of HAIs was 3.16% (301/9533). No significant dif-ferences were identified in the point prevalence measurements of HAIs in any of theyears from 2007 to 2011. Of all the cases, proportionally, the most frequent infectionsite was the respiratory tract (2.34%), followed by surgical sites (0.43%) and urinarytract sites (0.28%). Gram-negative aerobic bacilli were the most common organismsmentioned; the most frequently isolated organism was Pseudomonas aeruginosa,followed by Escherichia coli and Acinetobacter baumannii. Approximately one-halfof the patients were receiving antibiotics at the time of the surveys. Cephalosporin,penicillin, and quinolone were most commonly used for treatment or prevention.The differences found in HAI prevalence data across the 5 surveys given in the hospi-tal were not statistically significant. In conclusion, this successive point-prevalencesurvey provides information about the trend of HAI prevalence, epidemical char-acter, and the use of antibiotics among the university hospital’s in-patients. Thisinformation allows us to initiate targeted programs for infection prevention andcontrol.下载学习，谢谢老师分享！！ 英文水品不够，要努力学习，才能中外贯通，加油！ {:1_13:}好文章
