质控督查对提高血培养双套送检率的影响

Effect of Quality Control Supervision to Two Sets of Blood Culture

目的评价质控督查对提高住院患者血培养双套送检率的影响。方法上海市医院感染质控中心从2007年起对血培养双套送检率实施质控督查,包括制定督查的项目和评分标准、宣传培训和现场督查;市质控专家到各医院微生物实验室选取某一特定时间之前连续50例患者的血培养送检信息。结果 2006年69所医院血培养双套送检率为14.8%,通过宣传教育和质控督查,双套送检率明显上升,2007年为81.6%、2009年达90.2%,差异有统计学意义;血培养双套送检合格的医院比率也从4.3%升至86.9%。结论质控督查可使血培养正确送检率明显改善,对指导抗菌药物合理使用和提高重危的预后具有重要意义。

OBJECTIVE To evaluate the effect of quality control supervision to blood culture sampling. METHODS Several methods had been used to improve the quality of blood culture sampling from 2007, including formulating supervision criteria, training and supervision. The data of 50 cases of blood culture were collected on the spot from each hospital to estimate the quality of blood culture. The result of supervision were announced to the hospitals at the end of the year. RESULTS The average rate of two sets of blood cultures in 69 hospitals was only 14.8% in 2006. However, the average rate increased to 81.6% in 2007 and 90.2% in 2009 （P〈0.05） after education and supervision. The rate of the qualified hospitals increased from 4.3% in 2006 to 86.9% in 2009. CONCLUSIONS The quality control supervision of blood cultures sampling can obviously improve the detection rate. And it has great importance to the rational use of clinical antimicrobial agents and improvement of the prognosis of severe cases.
