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=.

Cholesterol and serum albumin as risk factors for death in patients undergoing general surgery.

Background: Serum levels of total cholesterol, its fractions (high-density lipoprotein-cholesterol (HDL-C) and low-density lipoprotein-cholesterol) and albumin are related to a poor outcome during hospital stay. It has been not assessed whether they are related to death in the long term after general surgery.

Methods: This prospective cohort study included 2848 general surgical patients with a median follow-up of 6 years after discharge from hospital.

Indices of surgical site infection risk and prediction of other adverse outcomes during hospitalization.

Objective: To assess which adverse postsurgical outcomes are best predicted by the Study on the Efficacy of Nosocomial Infection Control (SENIC) index and the National Nosocomial Infection Surveillance system (NNIS) index.

Design: Prospective cohort study.

Setting: The service of general surgery at a tertiary care hospital.

Alcohol consumption and the risk of nosocomial infection in general surgery.

Background: Alcohol consumption increases community-acquired infections and affects the immune system. The aim of this report was to analyse whether drinking increases the risk of nosocomial infection.

Methods: This was a prospective study of 1505 patients admitted consecutively to a general surgical department.
