A Review of Professional Liability in IR: Sweeping the Mines.

Medical professional liability (MPL) is becoming a substantial issue in interventional radiology (IR), with both impact on health care costs and negative psychological effects on physicians. MPL presents special challenges within IR because of the field's complex and innovative therapies that are provided to a diverse group of patients and complicated by the off-label use of devices and drugs that is pervasive in the field. This review discusses the principles and practices to avoid and manage MPLs that are specific to the field of IR.

Implementation of a hybrid angiography-CT system: increased short-term revenue at an academic radiology department.

PURPOSE: To analyze the financial impact following implementation of a hybrid Angio-CT system at a tertiary care academic medical center. METHODS: Aggregate case types and volumes were compared 24 months before and 12 months after a hybrid Angio-CT system replaced a traditional interventional C-arm angiography suite at an academic medical center. Procedure revenues from this 36-month study period were derived from five payors mixes (Medicare, Medicaid, commercial insurance, out-of-pocket and managed care program) and Medicare-rate adjusted to each individual payor types. RESULTS: Average case volume per month increased 12% in the hybrid Angio-CT suite when compared to the previous traditional angiography suite (P < 0.05). The variety of IR procedures in the hybrid Angio-CT suite also expanded to include more complex interventional radiology and interventional oncology procedures; the breadth of cases performed in the hybrid Angio-CT suite were associated with CPT codes of higher rates (average CPT value/case increased from $2,334.61 to $2,567.25). The estimated average annual revenue of the hybrid Angio-CT suite increased 23% as compared to previous traditional angiography suite. CONCLUSION: A hybrid Angio-CT system is a financially feasible endeavor at a tertiary care academic medical center that facilitated higher complexity procedure codes and increased procedure-related revenue.

Assessment of complication rates based on time of feeding initiation in radiologically guided gastrostomy tubes: a retrospective study.

PURPOSE: We aimed to assess the association between complication rate and time to feeding in a cohort of patients undergoing radiologically guided placement of gastrostomy tubes. METHODS: A retrospective study was conducted of all patients receiving pull-type and push-type gastrostomy tubes placed by interventional radiologists between January 1st, 2017 and December 31st, 2018 at a single institution. Primary outcomes included procedural and tube-related complications per medical chart review with a follow-up interval of 30 days. Exclusion criteria were enteral nutrition delayed more than 48 hours, no feeding information, and tubes placed for venting (n=20). Overall, 303 gastrostomy tubes (pull-type, n=184; push-type, n=119) were included. The most common indications for placement included head and neck carcinoma for push-type tubes (n=76, 63.9%) and cerebral vascular accident for pull-type tubes (n=78, 42.4%). RESULTS: In a multiple regression analysis, there was no statistically significant association between complications and time to feeding (p = 0.096), age (p = 0.758), gender (p = 0.127), indication for tube placement (p = 0.206), or type of tube placed (p = 0.437). Average time to initiation of enteral nutrition was 12.3 hours for the pull-type and 21.7 hours for the push-type cohort (p < 0.001). Additional multiple regression analyses of pull-type tubes and push-type tubes separately also did not find any significant association between complications and the above factors (p > 0.05). CONCLUSION: There was no statistically significant correlation between time to feed and complications, suggesting that there is no clinical difference between early and late feeding following gastrostomy tube placement.

Interventional radiologic treatment of hepatocellular carcinoma-a cost analysis from the payer perspective.

PURPOSE: To determine whether there is a cost advantage for one of the three commonly performed interventional radiology (IR) procedures (chemoembolization, selective internal radiation therapy [SIRT], radiofrequency ablation [RFA]) in the treatment of hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A cost analysis from the payer perspective was performed. Primary data were collected from a university hospital, and sensitivity testing was done by comparing coding information obtained at two other tertiary care medical facilities. Medicare allowable reimbursements were used to estimate costs. Decision analytic models using decision tree analysis and Monte Carlo simulations were used to compare alternatives. Simulations were performed comparing all three procedures, followed by a two-way comparison of chemoembolization and SIRT. RESULTS: Simple decision tree analyses showed that RFA was less expensive compared with chemoembolization and SIRT. Monte Carlo simulations showed average reimbursements for each of the three procedures that was largely dependent on the number of repeat procedures required ($9,362 vs $30,107 vs $35,629 for RFA, chemoembolization, and SIRT; P < .001). When comparing only chemoembolization and SIRT, chemoembolization was the lower cost strategy in most scenarios, but SIRT was lower in cost in more than one-third of the simulations. CONCLUSIONS: RFA was the least costly of the three IR strategies in nearly all scenarios studied in these models. Although chemoembolization was less expensive than SIRT in most instances, Monte Carlo simulation showed a preference for SIRT in more than one-third of all scenarios. Sensitivity analyses showed that the most important variables assessed were the need for repeat procedures.

ACR Appropriateness Criteria® on treatment of uterine leiomyomas.

Uterine leiomyomas (fibroids) are the most common tumors in women of reproductive age and a cause of significant morbidity in this patient population. Depending on the fibroid location, they can be the cause of a variety of symptoms, such as abnormal uterine bleeding, constipation, urinary frequency, and pain. Historically, hysterectomy has been the primary treatment option, and uterine fibroids remain the leading cause for hysterectomy in the United States. However, women who do not wish to undergo hysterectomy now have a variety of less invasive options available, including uterine artery embolization. This article discusses uterine artery embolization as well as some of the other treatment strategies for symptomatic uterine fibroids. In many situations, there may be no single best treatment option but several viable alternatives. Each option is discussed with consideration of outcomes, complications, and, when possible, cost-effectiveness. The recommendations in this article are the result of evidence-based consensus of the ACR Appropriateness Criteria® Expert Panel on Interventional Radiology.
