Influences and countermeasures of catheter-related bloodstream infections with peripherally inserted central catheters in ICU

Abstract

Objective To analyze the influences of catheter related bloodstream infection (CRBSI) for ICU patients with PICC. Methods Information and documents of 164 PICC patients were collected from October 2014 to December 2016, general information, intravenous drugs and skin conditions were analyzed if they have any impacts on CRBSI. Results Sixteeen patients with CRBSI and 148 patients with non-CRBSI. The acute physiology and chronic health evaluation (APACHE Ⅱ) score, hospitalization time, PICC catheterization time was (22.25 ± 4.95) points, (99.44 ± 57.34) d, (67.44 ± 48.30) d in CRBSI patients, and (14.64±6.86) points, 21.00(22.00) d, 12.00 (14.00) d in non-CRBSI patients. There were significant differences (U=439.00, 299.00, 383.00, all P<0.01). The incidence of injection of vasoactive drugs and skin edema were accounted for 8/16, 10/16 in CRBSI patients, and 25.00%(37/148), 31.08%(46/148) in non-CRBSI patients, the difference was statistically significant (χ2=4.53, 6.34, P<0.05). The APACHE II score was an independent risk factor for PICC catheter-related infections (OR=1.21, P<0.01). Conclusions The environment in ICU is quite complicated and patients often have the characteristic of instability, which drives us to evaluate the influence factors of CRBSI and offer guidance for PICC maintenance. These can help reduce the incidence of CRBSI in ICU and improve the quality of patients.
