Exposure to potential pathogens on contaminated healthcare garments and curtains can occur through direct or indirect contact. This study aimed to identify the microorganisms present on podiatry clinic curtains and measure the contamination pre and post a standard hospital laundry process.
Baseline swabs were taken to determine colony counts present on cubical curtains before laundering. Curtains were swabbed again immediately after, one and three weeks post laundering. Total colony counts were calculated and compared to baseline, with identification of micro-organisms.
Total colony counts increased very slightly by 3% immediately after laundry, which was not statistically significant, and declined significantly (p = 0.0002) by 56% one-week post laundry. Three weeks post laundry colony counts had increased by 16%; although clinically relevant, this was not statistically significant. The two most frequent microorganisms present throughout were Coagulase Negative Staphylococcus and Micrococcus species. Laundering was not completely effective, as both species demonstrated no significant change following laundry.
This work suggests current laundry procedures may not be 100% effective in killing all microorganisms found on curtains, although a delayed decrease in total colony counts was evident. Cubicle curtains may act as a reservoir for microorganisms creating potential for cross contamination. This highlights the need for additional cleaning methods to decrease the risk of cross infection and the importance of maintaining good hand hygiene.
医护人员的服装和窗帘若受到污染,可能会通过直接或间接接触暴露于潜在的病原体。本研究旨在确定足病诊所窗帘上存在的微生物,并测量标准医院洗衣程序前后的污染情况。
在洗涤前,对立方窗帘进行基线拭子采样,以确定洗涤前的菌落计数。洗涤后立即、洗涤后一周和三周再次对窗帘进行拭子采样。计算总菌落计数并与基线进行比较,并对微生物进行鉴定。
洗涤后立即,总菌落计数略有增加 3%,但无统计学意义,洗涤后一周下降 56%,有显著差异(p = 0.0002)。洗涤后三周,菌落计数增加了 16%;尽管具有临床相关性,但无统计学意义。整个过程中最常见的两种微生物是凝固酶阴性葡萄球菌和微球菌属。洗涤并不完全有效,因为这两种微生物在洗涤后都没有明显变化。
本研究表明,目前的洗衣程序可能无法 100%有效地杀死窗帘上发现的所有微生物,尽管总菌落计数明显减少。病房窗帘可能是微生物的储存库,从而存在潜在的交叉污染风险。这突显了需要额外的清洁方法来降低交叉感染的风险,以及保持良好手部卫生的重要性。
