Use of the national noscomial infection surveillance system risk index for prediction of mortality: results of a 6-year postdischarge follow-up study.
A positive linear trend (P<.001) between the National Noscomial Infection Surveillance system (NNIS) risk index and mortality was observed in 2,848 general surgery patients followed up 6 years after discharge. In stratified analyses, the NNIS risk index predicted mortality in patients with chronic disease (P=.007, by test for trend) but not in the remaining patients.
