Although strict adherence to infection control strategies is recognised as the simplest and most cost effective method to prevent the spread of healthcare associated infections (HAIs), measurement of the direct impact that such adherence may have on the risk of developing such infections has always been a challenge.
The purpose of this study was to compare the risk of HAIs before and during the SARS outbreak. Such comparison is intended to provide a surrogate measure of the influence that strict enforcement of infection control strategies during the SARS outbreak may have had on the risk of HAIs.
A retrospective chart review was conducted on the medical records of 400 intensive care patients who were admitted to the ICU three months before and during the 2003 SARS outbreak.
The rate of HAIs was higher in the pre-SARS period than the SARS period. Specifically, 61.7% of all reported infections were diagnosed in the pre-SARS period. The rate of HAIs in the pre-SARS period was 14.5% as opposed to 9% during the SARS period. Adjusted logistic regression analysis suggested that the odds of HAIs were 2.2 times higher in the pre-SARS period as compared to the SARS period (OR=2.2; 95%CI=1.08-4.49).
Our findings suggest that strict enforcement of infection control strategies may have a positive impact on the efforts to minimise the risk of HAIs. These findings carry a clinical significance that shall not be ignored with regard to our overall efforts to minimise the risk of developing HAIs in the ICU.
尽管严格遵守感染控制策略被认为是预防医院获得性感染（HAIs）传播的最简单、最具成本效益的方法，但衡量这种遵守对发生此类感染的风险的直接影响一直是一个挑战。
本研究旨在比较 SARS 爆发前后的 HAI 风险。这种比较旨在提供一种替代措施，以衡量 SARS 爆发期间严格执行感染控制策略对 HAI 风险的影响。
对 ICU 收治的 400 名重症监护患者的病历进行回顾性图表审查，这些患者在 SARS 爆发前三个月和 SARS 爆发期间入住 ICU。
SARS 爆发前的 HAI 发生率高于 SARS 期间。具体来说，所有报告的感染中有 61.7%是在 SARS 爆发前诊断的。SARS 爆发前的 HAI 发生率为 14.5%，而 SARS 期间为 9%。调整后的逻辑回归分析表明，与 SARS 期间相比，SARS 爆发前发生 HAI 的几率高 2.2 倍（OR=2.2；95%CI=1.08-4.49）。
我们的研究结果表明，严格执行感染控制策略可能对降低 HAI 风险的努力产生积极影响。这些发现具有临床意义，不容忽视，因为我们总体上努力降低 ICU 发生 HAI 的风险。
