Summary
Improving retrievable inferior vena cava (IVC) filter removal is crucial. An intervention combining patient education and hematology follow-up significantly increased IVC filter retrieval rates in a rural academic medical center.
Area of Science:
- Vascular Surgery
- Medical Interventions
- Health Services Research
Background:
- Published data reveal suboptimal retrieval rates for retrievable inferior vena cava (IVC) filters.
- Low retrieval rates pose risks, necessitating strategies for improvement.
Purpose of the Study:
- To evaluate the effectiveness of a multi-faceted intervention aimed at enhancing IVC filter retrieval rates.
- To assess the impact of patient education and hematology consultation on IVC filter removal.
Main Methods:
- A historic-controlled study was conducted over five years (March 2007-February 2012) at a rural university medical center.
- The intervention group received counseling, educational materials, and hematology follow-up; the control group did not.
- Adult patients with retrievable IVC filters, excluding those with <6 months life expectancy, were included.
Main Results:
- During the intervention, 378 IVC filters were placed, with 169 (45%) retrieved, compared to 116 placed and 27 (23%) retrieved in the control period.
- Statistical analysis, adjusting for patient characteristics, showed an odds ratio of 3.03 (95% CI 1.85-4.27) for filter retrieval during the intervention.
Conclusions:
- A comprehensive intervention involving patient education and hematology follow-up significantly improved IVC filter retrieval rates.
- This strategy offers a viable approach to enhance patient safety and optimize the use of retrievable IVC filters.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

313
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
