Insights
Practice improvements have reduced central venous access device (CVAD) failure in children, but challenges remain. Further innovation is needed to enhance vessel health and preservation during CVAD insertion and use.
Area of Science:
- Paediatric Medicine
- Vascular Access
- Medical Device Technology
Background:
- Central venous access devices (CVADs) are crucial for managing paediatric patients.
- Understanding practice evolution, complications, and failure risk factors is essential for optimizing care.
- Previous data on CVAD outcomes in children requires updated analysis.
Purpose of the Study:
- To analyze trends in paediatric central venous access device (CVAD) practices.
- To identify complications and risk factors associated with multiple insertion attempts.
- To determine factors contributing to CVAD device failure in paediatric populations.
Main Methods:
- Retrospective cohort study utilizing prospectively collected data from a paediatric CVAD database (2012-2014).
- Inclusion of patient demographics, insertion details (indication, device, technique), and removal data (complications, dwell time).
- Statistical analysis included descriptive statistics, incidence rates, logistic regression for insertion attempts, and Cox regression for failure.
Main Results:
- A total of 1308 CVADs in 863 patients were analyzed; multiple insertion attempts remained static at 14%.
- CVAD failure rates decreased from 35% in 2012 to 25% in 2014.
- Risk factors for failure varied by device type, including patient condition (e.g., gastroenterology diagnosis), insertion site, and patient characteristics (e.g., body weight, age).
Conclusions:
- Advancements in CVAD practices have led to improved insertion and failure outcomes in paediatric patients.
- Despite improvements, persistent challenges necessitate further innovation in CVAD management.
- Focus on enhancing vessel health and preservation is critical for children requiring CVADs.
Aim:
To describe practice evolution, complications and risk factors for multiple insertion attempts and device failure in paediatric central venous access devices (CVADs).
Methods:
A paediatric retrospective cohort study using prospectively collected data from CVAD database 2012-2014. Data included were patient (i.e. age, condition), insertion (i.e. indication, device, technique) and removal (complications, dwell). Descriptive statistics and incidence rates were calculated per calendar year and compared. Risk factors for multiple insertion attempts and failure were explored with logistic regression and cox regression, respectively.
Results:
A total of 1308 CVADs were observed over 273 467 catheter-days in 863 patients. Multiple insertion attempts remained static (14%) and significantly associated with non-haematological oncology (odds ratio 2.19; 95% confidence interval (CI) 1.08-4.43), respiratory (3.71; 1.10-12.5), gastroenterology (4.18; 1.66-10.5) and other (difficult intravenous access) (2.74; 1.27-5.92). CVAD failure decreased from 35% (2012) to 25% (2014), incidence rate from 1.50 (95% CI 1.25-1.80) to 1.28 (1.06-1.54) per 1000 catheter-days. Peripherally inserted CVAD failure was significantly associated with lower body weight (per kilogram decrease, hazard ratio (HR) 1.02; 95% CI 1.00-1.03), cephalic vein (1.62; 1.05-2.62), difficult access (1.92; 1.02-3.73), sub-optimal tip placement (1.69; 1.06-2.69) and gastroenterology diagnosis (2.27; 1.05-4.90). Centrally placed CVAD failure was significantly associated with younger age (per year, HR 1.04; 95% CI 1.00-1.07), tunnelled device (3.38; 2.41-4.73) and gastroenterology diagnosis (1.70; 1.06-2.73).
Conclusions:
While advancement in CVAD practices improved overall CVAD insertion and failure outcomes, further improvements and innovation are necessary to ensure improved vessel health and preservation for children requiring CVAD.
