Risk Factors for Nosocomial Infection

Purpose: Purpose: To identify a hospitalized adult patient at increased risk for a nosocomial infection based on the risk factors of Schneider et al.

Description

Schneider et al identified risk factors associated with nosocomial infections in non-selected hospital inpatients. These can help identify patients who may benefit from more aggressive management. The authors are from CHU de Nice and CHU de Besancon in France.


Patient selection: adult inpatients

 

Primary types of noocomial infections:

(1) urinary tract

(2) surgical site

(3) respiratory tract

(4) skin and soft tissue

(5) vascular catheter

 

Factors associated with moderate risk (odds ratio 9.0 to 10.4)

(1) current weight < 50 kilograms

(2) presence of a urinary catheter

 

Factors associated with mild to moderate risk (odds ratio 5.0)

(1) intermediate to long-stay (vs acute stay)

(2) length of stay > 7 days (would cover item 1)

(3) nutritional risk index (NRI) < 83.5 (indicating severe malnutrition; see chapter 12)

 

Factors associate with mild risk (odds ratio 1.4 to 3.0):

(1) nutritional risk index (NRI) 83.5 to 97.5 (indicating mild to moderate malnutrition)

(2) presence of a vascular catheter (I assume a central venous catheter)

(3) age > 40 years

(4) plasma albumin < 35 g/L)

(5) immunodeficiency

(6) surgical intervention
