Insights
Vascular closing devices (VCDs) significantly reduce complication rates and costs in interventional catheterization. Their cost-effectiveness also supports wider use in diagnostic catheterization, though hospital stay duration remains unchanged.
Area of Science:
- Cardiovascular Medicine
- Medical Devices
- Health Economics
Background:
- Catheterization procedures carry risks of complications and associated costs.
- Manual compression is a traditional method for achieving hemostasis post-catheterization.
- Vascular closing devices (VCDs) offer an alternative to manual compression for hemostasis.
Purpose of the Study:
- To compare complication rates, hospital stay length, and costs between manual compression and VCDs.
- To evaluate VCD efficacy in both diagnostic and interventional catheterization.
- To assess the economic impact of VCDs in a German university hospital setting.
Main Methods:
- Retrospective, cross-sectional, single-center study.
- Stratified analysis by risk profiles and propensity score adjustment.
- Generalized linear models with gamma distribution for cost and length of stay analysis.
Main Results:
- VCDs significantly lowered complication rates in interventional catheterization (RR=0.44).
- VCDs resulted in lower average costs for both diagnostic (€275) and interventional (€373) catheterization.
- No significant difference in length of hospital stay was observed between VCDs and manual compression.
Conclusions:
- Vascular closing devices are effective in reducing complications and costs for interventional catheterization.
- The cost savings associated with VCDs justify their broader implementation in diagnostic catheterization.
- VCDs represent a valuable tool for improving efficiency and patient outcomes in cardiac catheterization procedures.
Objectives:
To compare complication rates, length of hospital stay, and resulting costs between the use of manual compression and a vascular closing device (VCD) in both diagnostic and interventional catheterization in a German university hospital setting.
Methods:
A stratified analysis according to risk profiles was used to compare the risk of complications in a retrospective cross-sectional single-center study. Differences in costs and length of hospital stay were calculated using the recycled predictions method, based on regression coefficients from generalized linear models with gamma distribution. All models were adjusted for propensity score and possible confounders, such as age, sex, and comorbidities. The analysis was performed separately for diagnostic and interventional catheterization.
Results:
The unadjusted relative risk (RR) of complications was not significantly different in diagnostic catheterization when a VCD was used (RR = 0.70; 95% confidence interval [CI] 0.22-2.16) but significantly lower in interventional catheterization (RR = 0.44; 95% CI 0.21-0.93). Costs were on average €275 lower in the diagnostic group (95% CI -€478.0 to -€64.9; P = 0.006) and around €373 lower in the interventional group (95% CI -€630.0 to -€104.2; P = 0.014) when a VCD was used. The adjusted estimated average length of stay did not differ significantly between the use of a VCD and manual compression in both types of catheterization.
Conclusions:
In interventional catheterization, VCDs significantly reduced unadjusted complication rates, as well as costs. A significant reduction in costs also supports their usage in diagnostic catheterization on a larger scale.
