2014—2022年手卫生干预对医院感染例次发病率的影响

目的 观察多模式手卫生干预对手卫生依从性的影响,以及手卫生依从性与医院感染例次发病率之间的关系。方法 2014—2022年,某三甲医院感染控制团队对全院医务人员实施多模式手卫生干预,回顾性分析手卫生监测数据的变化趋势、手卫生依从率与医院感染例次发病率的相关性。结果 病房手卫生用品消耗量呈稳定上升趋势;手卫生依从率从2014年64.98%提高到2022年85.01%(P<0.001),医院感染例次发病率从1.21%下降至0.83%(P<0.05),手卫生依从率与医院感染例次发病率之间存在负相关(r=-0.369,P=0.027)。各季度不同区域及不同岗位的手卫生依从率均有所提高(P<0.001)。各季度5个时刻手卫生依从率中,无菌操作前与接触患者后的手卫生依从率小幅波动;接触患者周围环境后的手卫生依从率呈上升趋势;接触患者前与接触患者体液后的手卫生依从率在2020年之后有所下降(P<0.001)。结论 多模式手卫生干预能提高医务人员的手卫生依从性,提高医务人员手卫生意识有利于降低医院感染例次发病率。

某医院工作人员个人防护用品新冠病毒核酸污染情况调查

目的了解新冠病毒感染的肺炎定点医院工作人员的个人防护用品和裸露皮肤上新冠病毒核酸污染情况,为科学防护提供依据。方法采用PCR检测方法,对新冠病毒感染疫情期间某定点医院工作人员个人防护用品等物品新冠病毒核酸污染情况进行评价。结果共调查该定点医院110名工作人员,采集各个人防护用品、衣服和皮肤样本1130份,检出核酸阳性24份,检出率为2.12%。采集手套、防护服、外层靴套和防护面屏等样本,每种110份,核酸阳性检出率依次为10.00%、5.45%、5.45%和0.91%。ICU工作人员手套上检出核酸阳性率为18.75%。实施针对性改进措施后防护服和手套上病毒核酸检出率均明显低于实施前(χ2=7.288和21.516,P<0.05)。结论新冠定点医院工作人员手套、防护服和鞋套上新冠病毒核酸检出率较高,应加强病区环境清洁消毒。

Clinical observation on electroacupuncture plus Yi Jin Jing(Sinew-transforming Qigong Exercises)for knee osteoarthritis

Objective:To observe the efficacy of electroacupuncture(EA)plus Yi Jin Jing(Sinew-transforming Qigong Exercises)for knee osteoarthritis(KOA).Methods:A total of 60 patients with KOA were divided into an observation group and a control group according to the random number table method,with 30 cases in each group.Patients in the observation group received the treatment of EA plus Yi Jin Jing(Sinew-transforming Qigong Exercises),while patients in the control group only received EA treatment.Both groups were treated for 5 weeks.The changes of Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)and visual analog scale(VAS)scores in the two groups were observed after treatment.Results:After treatment,the total effective rate in the observation group(92.3%)was significantly higher than that in the control group(70.0%),(P<0.05);the WOMAC and VAS scores in both groups were significantly lower than those before treatment,showing statistical significance(all P<0.01);there were significant differences in the post-treatment changes in the WOMAC and VAS scores between the two groups(P<0.05,P<0.01).Conclusion:EA plus Yi Jin Jing(Sinew-transforming Qigong Exercises)is clinically effective for KOA.This combined treatment can alleviate clinical symptoms.
