Patient selection: in pediatric ICU (a few adults included)
Outcome: CLABSI
Risk factors for CLABSI:
(1) parenteral nutrition (odds ratio 3.1)
(2) transfusion of packed red blood cells (odds ratio 2.6)
(3) gastrostomy tube (odds ratio 3.5)
(4) duration of ICU central catheter (odds ratio 14.7 for 4 to 14 days and 18.4 for >= 15 days)
(5) number of central lines placed in the ICU (odds ratio 8.6 for 2 or more and 2.4 for 1)
(6) combination of cardiovascular disease and no surgery (odds ratio 7.4)
(7) combination of cardiovascular disease and surgery (odds ratio 2.2)
cumulative product of odds ratios =
= PRODUCT(odds ratios for all of the parameters)
Interpretation:
• minimum cumulative product: 1
• maximum cumulative product: 33,033
• The greater the cumulative product the greater the risk of CLABSI.
