摘要
目的了解多药耐药菌目标性监测的数据,评价监测与干预的效果。方法前瞻性监测与时时干预,利用χ2检验比较2009年及2010年耐甲氧西林金黄色葡萄球菌(MRSA)的分离率、医院获得性MRSA(HA-MRSA)的构成比及在ICU分布。结果 2009年共收集金黄色葡萄球菌165株,检出MRSA75株,检出率为45.5%,其中HA-MRSA为53株,占70.7%;2010年共收集金黄色葡萄球菌228株,检出MRSA 61株,检出率为26.8%,其中HA-MRSA为33株,占54.1%;两年的MRSA检出率及HA-MRSA所占比率比较,差异有统计学意义(χ2=14.792,P<0.01;χ2=3.972,P<0.05)。结论监测和干预措施效果明显。
OBJECTIVE To analyze the data on multidrug-resistant organism supervision and to evaluate the effect of supervision and intervention. METHODS Prospective supervision and on-site intervention were performed to collected specimen,and χ2 statistical method was used to compare the separation rate,the constituent ratio,and the distribution. RESULTS Totally 165 strains of Staphylococcus aureus were collected in 2009,and 75 strains of MRSA were detected with the detection rate of 45.5%,among which,53 strains were HA-MRSA,accounting for 70.7%;totally 228 strains of S.aureus were collected in 2010,61 strains of MRSA were detected with the detection rate of 26.8%,among which 33 strains were HA-MRSA,accounting for 54.1%.The differences of detection rate of MRSA and the percentage of HA-MRSA between 2009 and 2010 were statistically significant（χ2=14.792,P0.01;χ2=3.972,P0.05）. CONCLUSION Surveillance and intervention measures have significant effect in preventing and controlling infection.
