Development of a statewide program for surveillance and reporting of hospital-acquired infections

Abstract

In 1974, a statewide program was begun to improve surveillance of nosocomial infection in Virginia hospitals. Infection control practitioners were trained at the University of Virginia Hospital, Charlottesville, and were encouraged to submit monthly surveillance reports for analysis. In the first three years of the project, 141 students from 65 hospitals within the state attended a two-week basic course, with eight to 10 students per class. Of the 98 Virginia hospitals that sent students, 75 (73%) submitted monthly reports. The consistency of reporting (number of monthly reports received divided by the number of possible reporting months) was 83%. The sensitivity of reported data was estimated in comparative daily prospective surveys to be 69% for participating hospitals, and the specificity was 99%. The crude infection rate for the first 1.1 million patients at risk was 3.3%.
