Gloves and gowns are used during patient care to reduce contamination of personnel and prevent pathogen transmission.
To determine whether the use of gowns adds a substantial benefit over gloves alone in preventing patient-to-patient transfer of a viral DNA surrogate marker.
In total, 30 source patients had 1 cauliflower mosaic virus surrogate marker applied to their skin and clothing and a second to their bed rail and bedside table. Personnel caring for the source patients were randomized to wear gloves, gloves plus cover gowns, or no barrier. Interactions with up to 7 subsequent patients were observed, and the percentages of transfer of the DNA markers were compared among the 3 groups.
In comparison to the no-barrier group (57.8% transfer of 1 or both markers), there were significant reductions in transfer of the DNA markers in the gloves group (31.1% transfer; odds ratio [OR], 0.16; 95% confidence interval [CI], 0.02-0.73) and the gloves-plus-gown group (25.9% transfer; OR, 0.11; 95% CI, 0.01-0.51). The addition of a cover gown to gloves during the interaction with the source patient did not significantly reduce the transfer of the DNA marker (P = .53). During subsequent patient interactions, transfer of the DNA markers was significantly reduced if gloves plus gowns were worn and if hand hygiene was performed (P < .05).
Wearing gloves or gloves plus gowns reduced the frequency of patient-to-patient transfer of a viral DNA surrogate marker. The use of gloves plus gowns during interactions with the source patient did not reduce transfer in comparison to gloves alone.
在患者护理过程中使用手套和长袍可减少人员污染并防止病原体传播。
确定在预防病毒 DNA 替代标志物从患者到患者的转移方面，穿长袍是否比单独戴手套有实质性的益处。
总共 30 名源患者将 1 个花椰菜 mosaic 病毒替代标志物应用于其皮肤和衣物，以及另一个应用于其床栏和床头柜。照顾源患者的人员被随机分配戴手套、手套加覆盖长袍或不使用任何屏障。观察了与多达 7 名后续患者的相互作用，并比较了 3 组之间 DNA 标志物的转移百分比。
与无屏障组（1 或两者标志物的转移率为 57.8%）相比，戴手套组（DNA 标志物的转移率为 31.1%；优势比[OR]，0.16；95%置信区间[CI]，0.02-0.73）和戴手套加长袍组（DNA 标志物的转移率为 25.9%；OR，0.11；95% CI，0.01-0.51）的 DNA 标志物转移明显减少。在与源患者相互作用期间，将覆盖长袍添加到手套中并没有显著降低 DNA 标记物的转移（P =.53）。在随后的患者相互作用中，如果戴手套加长袍和进行手部卫生，则 DNA 标志物的转移明显减少（P <.05）。
戴手套或手套加长袍可降低病毒 DNA 替代标志物从患者到患者的转移频率。与单独戴手套相比，在与源患者相互作用期间使用手套加长袍并不能减少转移。
