Abstract
Review of current methods of surveillance for nosocomial infection indicates that prospective surveillance of patients on a daily basis is the most accurate and valid method. In this paper, we detail such a method. Samples of hospitalized patients for surveillance are based on a fixed period of observation in each patient-care area. Data are collected on a detailed, standardized daily log that emphasizes the recording of primary clinical data. Such a system is practical and is acceptable to infection control practitioners. Representative samples of patients are obtained. The utility of such a system for identifying preventable risk factors for the development and evaluation of programs of prevention is being tested in 12 acute-care hospitals in Rhode Island.
