Total parenteral nutrition catheter sepsis: impact of the team approach.
For a period of 32 months from the inception of the Parenteral and Enteral Nutrition (PEN) Team at the University of Michigan, the infection rate (IR) related to central venous catheters (CVCs) for total parenteral nutrition (TPN) was prospectively evaluated. Six hundred twenty-two catheters were placed in 377 patients for a total of 9,200 patient days. The length of CVC stay ranged from 2 to 108 days with a mean of 14.5. CVC longevity was longer on units where certification of nurses by the PEN team was mandatory (mean 20.4 days, IR 3.5%) vs comparable units which utilized informal instruction (mean 14.4 days, IR 3.5%). Twenty-two catheters led to patient sepsis for a rate of 3.5%, or 2.39 CVC-related infections per 1000 patient days. The preteam infection rate was 24.0%, as determined by a 6-month prospective study. Infection rates for CVCs used for TPN only and those used for parenteral nutrition (PN) plus blood products, antibiotics, and CVP measurements were identical, 3.5%. The team approach can effectively increase PN catheter longevity and reduce infection rates. Conservative cost accounting of best and worst case scenarios determined a range of $3,700 to $8,900 per episode of catheter sepsis.
