OBJECTIVE: To identify the prevalence and risk factors for complications associated with percutaneously inserted central venous catheters (PICCs) and evaluate the effect of different catheter types and their indwelling time on catheter-related complications. DESIGN: Retrospective cohort study. SETTING: A 49-bed neonatal intensive-care teaching hospital in Taiwan. PATIENTS: Between 2004 and 2007, 518 single-lumen PICCs (defined as "old type") and 290 PICCs with a stiffening stylet and a thicker introducer ("new type") were inserted in a total of 534 neonates with a birth body weight of 1,500 g or less. RESULTS: Independent risk factors of catheter-related sepsis (CRS) were longer duration for PICC placement and PICC inserted at femoral site (compared with nonfemoral sites) (odds ratio [OR], 1.53 [95% confidence interval {CI}, 1.07-2.25]; P = .044). An independent predictor of catheter-related noninfectious complications was time spent for PICC insertion of more than 60 minutes (compared with less than 30 minutes) (OR, 1.96 [95% CI, 1.08-3.53]; P = .026). New-type PICCs were significantly associated with a higher rate of femoral site insertion, catheter-related noninfectious complications, and longer time for successful insertion than old-type PICCs. The hazard rates of CRS according to indwelling time, determined over 5-day periods by survival analysis, showed 0.05% for catheters in place for 4 days or less; 0.27% for 5-9 days; 0.40% for 10-14 days; 0.68% for 15-19 days; 1.18% for 20-24 days; 3.96% for 25-29 days; and 10.45% for 30 or more days. CONCLUSIONS: Different catheters do influence the complication rates. Spending more than 60 minutes for successful PICC insertion and PICCs indwelling for more than 30 days are associated with higher rates of catheter-related complications.
