Racial, ethnic, and sex-based healthcare disparities have been documented for the past several decades. Nonetheless, disparities remain firmly entrenched in our care delivery systems, with multiple ...contributing factors, including patient interactions with care providers, systemic barriers to access, and socioeconomic determinants of health. Interventional radiology is also subject to these drivers of health inequity. In this review, documented disparities for the most common conditions being addressed by interventional radiologists are summarized; their magnitude is quantified where relevant, and underlying drivers are identified. Specific examples are provided to illustrate how medical, cultural, and socioeconomic factors interact to produce unequal outcomes. By outlining known disparities and common contributors, this review aims to motivate future efforts to mitigate them.
To determine the impact, if any, of the 2010 FDA safety communication on the rate of inferior vena cava filter (IVCF) placement over time.
The Nationwide Inpatient Sample was interrogated for the ...most recent years preceding and after the FDA safety communication-from 2005 to 2014. IVCF placements and associated diagnoses were identified using corresponding International Classification of Diseases, version nine codes. Trends in number of IVCF placement were evaluated in aggregate and by associated diagnoses, both of which were further stratified by hospital geographic cluster, hospital teaching status, and patient demographics. Generalized linear regression models were used to determine statistical significance of trends over time.
IVCF placements steadily increased between 2005 and 2010 (100,434 in 2005 versus 129,614 in 2010, growth rate 5.81%). Aggregate IVCF placements subsequently declined between 2010 and 2014 (96,005 in 2014, decline rate -6.48%). IVCF placements peaked in 2010, the year of the FDA advisory. The proportion of filter placements for therapeutic indication of venous thromboembolism increased significantly during the study period (69.8% in 2005 versus 80.4% in 2014, P < .001). Neither trend varied significantly by patient demographics or hospital characteristics.
IVCF placements have declined significantly since 2010, when the FDA advisory was released. The proportion of IVCFs placed in patients with venous thromboembolism, as opposed to prophylactic indications, is increasing.
Observational data research studying access, utilization, cost, and outcomes of image-guided interventions using publicly available "big data" sets is growing in the interventional radiology (IR) ...literature. Publicly available data sets offer insight into real-world care and represent an important pillar of IR research moving forward. They offer insights into how IR procedures are being used nationally and whether they are working as intended. On the other hand, large data sources are aggregated using complex sampling frames, and their strengths and weaknesses only become apparent after extensive use. Unintentional misuse of large data sets can result in misleading or sometimes erroneous conclusions. This review introduces the most commonly used databases relevant to IR research, highlights their strengths and limitations, and provides recommendations for use. In addition, it summarizes methodologic best practices pertinent to all data sets for planning and executing scientifically rigorous and clinically relevant observational research.
Background
Persistent controversy exists with regard to how and when patients with head and neck cancer should undergo imaging after definitive therapy. The current study was conducted to evaluate ...whether the type of imaging modality used in posttreatment imaging impacts cancer‐specific survival for patients with advanced head and neck squamous cell carcinoma.
Methods
A retrospective study of National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) program–Medicare‐linked data in patients with an advanced stage of the 3 most common head and neck malignancies (oral cavity, oropharynx, and larynx) was conducted. Hazard ratios and 95% CIs for cancer‐specific survival were estimated for patients diagnosed with any of these cancers between 2006 and 2015.
Results
Significant improvement with regard to cancer‐specific survival was observed among patients with American Joint Committee on Cancer stage III and stage IVA laryngeal cancer who underwent positron emission tomography (PET) and/or computed tomography (CT) imaging during the first 6 months after receipt of definitive treatment (hazard ratio, 0.517; 95% CI, 0.33‐0.811) compared with those who underwent CT. There was a trend toward an improvement in cancer‐specific survival among patients with oral cavity or oropharyngeal malignancies who underwent PET/CT imaging, but it did not reach statistical significance.
Conclusions
Compared with CT imaging, posttreatment imaging with PET was associated with improved survival in patients with advanced laryngeal carcinoma.
Persistent controversy exists regarding how and when patients with head and neck cancer should undergo imaging after receiving definitive therapy. The current study evaluates whether the type of imaging modality used in posttreatment imaging impacts cancer‐specific survival for patients with advanced head and neck squamous cell carcinoma and finds that, compared with computed tomography imaging, posttreatment imaging using positron emission tomography is associated with improved survival in patients with advanced laryngeal carcinoma.
Imaging guidelines for transient ischemic attack (TIA) recommend that patients undergo urgent brain and neurovascular imaging within 48 hours of symptom onset. Prior research suggests that most ...patients with TIA discharged from the emergency department (ED) do not complete recommended TIA imaging workup during their ED encounters. The purpose of this study was to determine the nationwide percentage of patients with TIA discharged from EDs with incomplete imaging workup who complete recommended imaging after discharge.
Patients discharged from EDs with the diagnosis of TIA were identified from the Medicare 5% sample for 2017 and 2018 using International Classification of Diseases, tenth rev, Clinical Modification codes. Imaging performed was identified using Current Procedural Terminology codes. Incomplete imaging workup was defined as a TIA encounter without cross-sectional brain, brain-vascular, and neck-vascular imaging performed within the subsequent 30 days of the initial ED encounter. Patient- and hospital-level factors associated with incomplete TIA imaging were analyzed in a multivariable logistic regression.
In total, 6,346 consecutive TIA encounters were analyzed; 3,804 patients (59.9%) had complete TIA imaging workup during their ED encounters. Of the 2,542 patients discharged from EDs with incomplete imaging, 761 (29.9%) completed imaging during the subsequent 30 days after ED discharge. Among patients with TIA imaging workup completed after ED discharge, the median time to completion was 5 days. For patients discharged from EDs with incomplete imaging, the odds of incomplete TIA imaging at 30 days after discharge were highest for black (odds ratio, 1.84; 95% confidence interval, 1.27-2.66) and older (≥85 years of age; odds ratio, 2.41; 95% confidence interval, 1.78-3.26) patients. Reference values were age cohort 65 to 69 years; male gender; white race; no co-occurring diagnoses of hypertension, hyperlipidemia, or diabetes mellitus; household income > $63,029; hospital in the Northeast region; urban hospital location; hospital size > 400 beds; academically affiliated hospital; and facility with access to MRI.
Most patients discharged from EDs with incomplete TIA imaging workup do not complete recommended imaging within 30 days after discharge.
To elucidate trends in transjugular intrahepatic portosystemic shunt (TIPS) use and outcomes over the course of a decade, including predictors of inpatient mortality and extended length of hospital ...stay.
The Nationwide Inpatient Sample was interrogated for the most recent 10 years available: 2003-2012. TIPS procedures and associated diagnoses were identified via International Classification of Diseases (version 9) codes, with the latter categorized into primary diagnoses in a hierarchy of disease severity. Linear regression analysis was used to determine trends of TIPS use and outcomes over time. Independent predictors of mortality and extended length of stay were determined by logistic regression.
A total of 55,145 TIPS procedures were captured during the study period. Annual procedural volume did not change significantly (5,979 in 2003, 5,880 in 2012). The majority of TIPSs were created for ascites and/or varices (84%). Inpatient mortality (12.5% in 2003, 10.6% in 2012; P < .05) decreased but varied considerably by diagnosis (from 3.7% to 59.3%), with a disparity between bleeding and nonbleeding varices (18.7% vs 3.8%; P < .01). Multivariate predictors of mortality (P < .001 for all) included primary diagnoses (bleeding varices, hepatorenal and abdominal compartment syndromes), patient characteristics (age > 80 y, black race), and sequelae of advanced cirrhosis (comorbid hepatocellular carcinoma, spontaneous bacterial peritonitis, encephalopathy, and coagulopathy).
National TIPS inpatient mortality has decreased since 2003 while procedural volume has not changed. Postprocedural outcome is a function of patient demographic and socioeconomic factors and associated diagnoses. Independent predictors of poor outcome identified in this large national population study may aid clinicians in better assessing preprocedural risk.
