医务人员及护工手部带菌情况调查

目的 了解医务人员及护工在临床工作中手部带菌情况,为加强手卫生管理提供科学依据.方法 对该院临床科室399名工作人员在临床工作时的手部随机进行卫生学采样,其中责任护士103名、办公护士75名、责任医师98名、住院总医师41名及护工82名,样本进行微生物学培养、鉴定.采样方法和手卫生合格情况判断按卫生部2012年版〈医院消毒卫生标准〉进行.结果 399名工作人员手卫生合格率为33.33%,合格率从高到低依次为责任护士（50.49%）、办公护士（38.67%）、责任医师（27.55）%、住院总医师（24.39%）、护工（19.51%）;平均菌落数为115.41 CFU/cm2.在399份手采样标本中,共培养出细菌738株,其中革兰阳性球菌170株（23.04%）,革兰阴性杆菌436株（59.08%）,革兰阳性杆菌132株（17.89%）;常见医院感染病原菌包括鲍曼不动杆菌（22株）、耐甲氧西林金黄色葡萄球菌（3株）.结论 医务人员及护工手部带菌情况普遍,需严格加强手卫生管理,降低手接触传播引起的院内交叉感染风险.

The survey of bacteria on the hand of medical staff and healthcare workers

Objective To know the hand bacteria carring situation of medical staff and care workers during the daily work,so as to provide a scientific basis for strengthening the management of hand hygiene. Methods The hand samples of 399 staff were col- lected for microbiological culture and identification, including 103 nurses, 75 office nurses, 98 responsible doctors, 41 resident doc- tors, and 82 care workers during the daily work. The assessments were made according to the ＂Hygienic standard for disinfection in hospitals＂ released by Ministry of Health in 2012. Results The total hand hygiene qualified rate of 399 staff was 33.33%. Hand hygiene qualified rate from high to low were as follows,nurses （50.49%） ,office nurses （38.67%） ,responsible doctors （27.55%）, resident doctors （24.39 %）, care workers （19.51 % ）. The general bacterial quantity were 115.41 CFU/cm^2. Fran 399 hand sam- ples,738 strains of bacteria were isolated totally,including＇ 170 strains of gram positive cocci（23.04 %） ,436 strains of gram negative bacillus（59.08%）, 132 strains of gram positive bacteria（ 17.89 %）. 22 strains of Acinetobacter baumannii, 3 strains of methicillin- resistant staphylococcus aureus were deteded which were common in hospital infection. Conclusion Hands carting bacteria are common in medical staff and workers, and therefore more attention should be paid to the management of hand hygiene to reduce the risk of nosocomial cross infection by hand contact.
