The Clinical Rationale for the Sentry Bioconvertible Inferior Vena Cava Filter for the Prevention of Pulmonary Embolism
The Sentry inferior vena cava (IVC) filter is designed to provide temporary protection against pulmonary embolism (PE) during transient high-risk periods and then to bioconvert after 60 days after implantation. At the time of bioconversion, the device's nitinol arms retract from the filtering position into the caval wall. Subsequently, the stable stent-like nitinol frame is endothelialized. The Sentry bioconvertible IVC filter has been evaluated in a multicenter investigational-device-exemption pivotal trial (NCT01975090) of 129 patients with documented deep vein thrombosis (DVT) or PE, or at temporary risk of developing DVT or PE, and with contraindications to anticoagulation. Successful filter conversion was observed in 95.7% of patients at 6 months (110/115) and 96.4% at 12 months (106/110). Through 12 months, there were no cases of symptomatic PE. The rationale for development of the Sentry bioconvertible device includes the following considerations: (1) the period of highest risk of PE for the vast majority of patients occurs within the first 60 days after an index event, with most of the PEs occurring in the first 30 days; (2) the design of retrievable IVC filters to support their removal after a transitory high-PE-risk period has, in practice, been associated with insecure filter dynamics and time-dependent complications including tilting, fracture, embolization, migration, and IVC perforation; (3) most retrievable IVC filters are placed for temporary protection, but for a variety of reasons they are not removed in any more than half of implanted patients, and when removal is attempted, the procedure is not always successful even with advanced techniques; and (4) analysis of Medicare hospital data suggests that payment for the retrieval procedure does not routinely compensate for expense. The Sentry device is not intended for removal after bioconversion. In initial clinical use, complications have been limited. Long-term results for the Sentry bioconvertible IVC filter are anticipated soon
Paperwork for the Busy Interventionalist: The Basic Six
Communication and patient care go hand in hand. Unfortunately, due to time constraints direct verbal communication with health care providers in every instance is not practical; it is also inefficient. Documentation is mandated by the Joint Commission on Accreditation of Healthcare Organizations and hospital bylaws. It reduces ambiguity and actually speeds communication between physician and hospital staff. Standard paperwork is recommended in most cases. Forms for patient admission, history and physical examination, daily patient rounds, preprocedural orders, consent form, discharge summary, and discharge orders allow the busy interventionalist to multitask with reasonable efficiency and fewer mistakes
The Basics of Interventional Radiology Management in a Large Radiology Group: A Bird's-Eye View
Through nearly 6 decades of growth we have enjoyed and suffered under many different types of management structures. From these experiences we have become believers in a central committee structure that advances our agenda with hospital administrators and third-party payers. The best way to illustrate what we think is a winning solution is by describing our present management system. Herein we describe what we do and what works for our large radiology group as well as our interventional practice. Although this structure works well for our large medical group, it will likely work equally well for a smaller medical group
Lessons Learned on How to Protect an Interventional Radiologist Against Malpractice Claims
Unfortunately, the risk of lawsuit is high for the interventional radiologist, especially for the one who assumes a more active clinical role in the care of patients. The importance of assuming this guardianship role in patient care is paramount to building an active referral base for reasons given in several accompanying articles in this issue. Because of added malpractice risks, it is important to fully understand the risks of this clinical role and how to protect yourself from potential lawsuits. This article discusses in depth steps, which can be taken to lessen the risk of a lawsuit, and steps to help effectively defend against a frivolous claim
Using Midlevel Providers in Interventional Radiology
Developing and implementing clinical services, including consultations, rounds, and clinic, is time-consuming, and for the interventional radiologist this means time away from the interventional laboratory. Using a team approach to providing clinical services is logical, and the midlevel provider is a perfect fit for an interventional radiology team. Midlevel providers can be grouped into two categories, advanced practice nurses (APNs) and physician's assistants (PAs). Under the umbrella of APN are several specialties including the nurse practitioner (NP), clinical nurse specialist (CNS), certified nurse midwife, and certified nurse anesthetist. The midlevel providers that are particularly suited for interventional radiology are the NPs, CNSs, and PAs. This article discusses midlevel providers in-depth including skills, limitations, and expenses
Coding Issues for Interventional Radiology: Get Paid for What You Do!
As interventional radiology continues to evolve into a true clinical practice, more time will be spent on the clinical decision process; this time is reimbursable in the form of evaluation and management (E&M) services. Once assumed to be an inherent part of the procedure itself, we know many procedures now do not include follow-up E&M components. Unfortunately, E&M coding is somewhat complex and requires rigorous documentation. Below is a discussion of the fundamentals of E&M services, general principles of documentation, and the mechanics of coverage and reimbursement
Differentiating Pharmacologic Agents Used In Catheter-Directed Thrombolysis
The use of catheter-directed thrombolysis is a proven treatment for arterial ischemia, deep vein thrombosis, and severe pulmonary embolism. For arterial ischemia, thrombolysis has resulted in improved amputation-free survival and fewer subsequent surgeries to reestablish blood flow to the ischemic limb. The management of patients with thromboembolic diseases is complex, and the multiple thrombolytic drugs available to choose from compound this complexity. Although some believe the available thrombolytic agents are interchangeable, real biochemical differences exist that may prove otherwise. This article describes these pharmacologic differences and how they may affect the clinical practice of catheter-directed thrombolysis
Establishing Surveillance Clinics: The Road to Success
Interventional radiology interacts with all medical disciplines and historically has not had a patient base of its own. The specialty has depended upon referrals for procedures (often complex) and not referrals for the global management of the disease process or patient. Because of this, when referrers develop catheter-based skills, referrals to interventional radiology drop and competition for primary care physician referrals increase; a double strike. To compete, interventional radiology needs to offer clinical services to the primary care physician. One way to compete is by establishing particular disease surveillance programs. Below we discuss in detail the process of establishing surveillance clinics, which one worked for us, and the expected outcomes of these clinics
