Increasing amounts of hospital data are available electronically and offer new possibilities in performing surveillance for health care-associated infections. To use electronic information effectively, health care epidemiologists need to be aware of potential sources of data, issues with data integrity, and the trade-offs in using electronic data for surveillance as opposed to traditional manual surveillance. In reality, a combined surveillance approach may provide the best possible result. A clear understanding of the epidemiologic principles, such as prevalence and incidence, and some of the nuances behind these principles are essential for the proper interpretation of the epidemiologic data.
越来越多的医院数据以电子方式提供，为进行医疗保健相关性感染的监测提供了新的可能性。为了有效地利用电子信息，医疗保健传染病专家需要了解潜在的数据来源、数据完整性问题，以及在使用电子数据进行监测与传统手动监测之间的权衡。实际上，结合使用监测方法可能会提供最佳结果。清楚了解流行率和发病率等流行病学原则以及这些原则背后的一些细微差别，对于正确解释流行病学数据至关重要。
