Abstract
Objective: Our object is to study risk factors of tumor patients’ PICC catheter-related blood stream infection. Method: a retrospective analysis of data of 586 PICC catheterized patients was implemented, a univariate analysis of general data and catheterizing data of tumor patients was then carried out, and data of single factors with statistical significance were incorporated into multi-factor Logistic regression model for analysis. Results: PICC catheter-related blood stream infection occurred to 16 patients, and occurrence rate was 2.73%. Multi-factor Logistic regression analysis results showed that number of puncturing times, positioning method and maintenance frequency were risk factors for tumor patients’ peripherally inserted central catheter catheter-related blood stream infection, and odds risk values were respectively 8.762, 9.253 and 10.324. Conclusion: for tumor patients implanted with peripherally inserted central catheters, using ECG positioning during strict sterile operation and catheterizing process to avoid repeated puncturing and increasing maintenance frequency could effectively reduce occurrence of PICC catheter-related blood stream infection.
Highlights
16 cases among 586 patients suffered from peripherally inserted central catheter (PICC) catheter-related blood stream infection, occurrence rate was 2.73%: which was lower than what’s reported in past researches [2] [3], and this might be related to the fact that only 16 patients infected with typical clinical manifestations like fever (>38 ̊C) and shivering were observed in this study but screening of patients without any symptom was not implemented
The study results showed that occurrence rate of symptomatic PICC-CRBSI was 2.73%, which was similar to what’s reported by many of the other scholars. 16 patients with occurrence of PICC-CRDSI in this study experienced obvious clinical symptoms, but PICC-CRBSI without delete typical clinical symptoms might exist in practical work, The occurrence rate of PICC-CRBSI might be far higher than existing reports, which might be related to the fact that high fever occurring in chemoradiotherapy of tumor patients was usually deemed as tumor-related fever without consideration of PICC-CRBSI
This indicated that medical personnel should blindly use antibiotics when faced with high fever of tumor patients carrying catheters not considering it as tumor-related fever, but instead, comprehensively considering whether patients had risks of PICC-CRBSI and make etiological quantitative examination when necessary
Summary
By virtue of advantages like once implantation with long-term utilization, few complications, possible bedside operation, reduction and prevention of risks caused by drug extravasation, etc., peripherally inserted central catheter (PICC) cathete-. PICC catheter-related blood stream infection (PICC-CRBSI) refers to that patients, who carry intravascular catheters or whose intravascular catheters are removed within 48 hours, suffer from bacteremia or fungemia accompanied by infectious manifestations like fever (>38 ̊C) and shivering and there is no any other infection source except intravascular catheter [2]. A retrospective analysis of 586 patients carrying PICC catheters was implemented in this paper and occurrence rate of PICC-CRBSI to tumor patients and its relevant risk factors were discussed so as to provide basis for clinical prevention of tumor patients’ PICC catheter-related blood stream infection
