RESUMO
PURPOSE: To investigate the degree to which morbidity and mortality (M&M) conferencing is utilized in interventional radiology (IR), identify impediments to its adoption, and assess the experience of those using this tool. MATERIALS AND METHODS: Members of the Society of Interventional Radiology (SIR) were offered a 9-question survey of practices and experiences regarding M&M conferencing within their quality assessment (QA) programs. RESULTS: Among 604 respondents, 37.8% were university-based practitioners and 60% were from outside of university practices. Of all respondents, 43% reported practicing 100% IR, with 28.5% practicing IR 75%-99% and 11% practicing IR <50% of the time. The use of M&M conferencing was significantly greater in university practices (90.7%) than in nonuniversity practices (37.1%) and among practitioners performing at least 75% IR (71.2%) than among those practicing <75% (28.8%). The conferences were held monthly (66.6%) or more often, and the majority (56%) of the events identified were scored using the SIR severity score. Approximately 20% of M&M conferences were multidisciplinary, shared most commonly with vascular surgery. The reasons cited for not using M&M included the lack of time and the logistical challenges of the process. However, among those who participate in M&M conferences, the QA goals of the conference were met at very high rates. CONCLUSIONS: M&M conferencing is well established in university IR programs and among full-time practitioners but much less so elsewhere. For those sites that do not utilize M&M conferencing, there may be a considerable benefit to addressing the obstacles that are limiting their implementation of this tool.

RATIONALE AND OBJECTIVES: To assess the efficacy and safety of percutaneous stenting for the palliative treatment of malignant superior vena cava syndrome (SVCS). METHODS AND MATERIALS: Literature review of retrospective studies was performed regarding direct procedural complications (fatal and non-fatal), clinical effectiveness, and patency rates (primary and secondary) of percutaneous transluminal stenting for the palliative treatment of malignant SVCS. Pooled rates and 95% confidence intervals were calculated for fatal complications, non-fatal complications, clinical effectiveness, primary patency, and secondary patency. Pooled rates were presented overall and by stent types (Wallstent, Nitinol stents, Steel stents and Stent Graft). Odds ratios and 95% confidence intervals were calculated to compare rates by stent type. RESULTS: Overall fatal complications rate was 1.46%, 95% CI [0.91 -2.23], non-fatal complications rate was 8.28%, 95% CI [6.91 -9.83], clinical effectiveness was 90.50%, 95% CI [88.86 -91.97], primary patency rate was 86.18%, 95% CI [84.06-88.12], secondary patency rate was 94.05 %, 95% CI [91.82 -95.82]. Primary patency rate of the Wallstent group was 83.38%, 95% CI [79.34 -86.90], and significantly higher for the Nitinol group 94.87%, 95% CI [87.40 -98.60], OR = 3.67, p = 0.01, and for the Stent Graft group 96.10%, 95% CI [89.00 -99.20], OR = 4.92, p = 0.01. Secondary patency rate for the Wallstent group was 93.33%, 95% CI [88.87 -96.40] and significantly lower for the Steel group 77.42%, 95% CI [58.90 -90.41], OR = 0.25, p = 0.01. CONCLUSION: Percutaneous stenting is a safe option for palliative treatment of patients with malignant SVCS with greater than 90% of patients experiencing immediate relief of symptoms, low rates of fatal complications (1.46%) and high patency rates (86.18% primary patency and 94.05% secondary patency).

BACKGROUND: There are "blind spots" on chest computed tomography (CT) where pulmonary nodules can easily be overlooked. The number of missed pulmonary nodules can be minimized by instituting a training program with particular focus on the depiction of nodules at blind spots. PURPOSE: The purpose of this study was to assess the variation in lung nodule detection in chest CT based on location, attenuation characteristics, and reader experience. MATERIALS AND METHODS: We selected 18 noncalcified lung nodules (6-8 mm) suspicious of primary and metastatic lung cancer with solid (n = 7), pure ground-glass (6), and part-solid ground-glass (5) attenuation from 12 chest CT scans. These nodules were randomly inserted in chest CT of 34 patients in lung hila, 1st costochondral junction, branching vessels, paramediastinal lungs, lung apices, juxta-diaphragm, and middle and outer thirds of the lungs. Two residents and two chest imaging clinical fellows evaluated the CT images twice, over a 4-month interval. Before the second reading session, the readers were trained and made aware of the potential blind spots. Chi-square test was used to assess statistical significance. RESULTS: Pretraining session: Fellows detected significantly more part-solid ground-glass nodules compared to residents (P = 0.008). A substantial number of nodules adjacent to branching vessels and posterior mediastinum were missed. Posttraining session: There was a significant increase in detectability independent of attenuation and location of nodules for all readers (P < 0.0008). CONCLUSION: Dedicated chest CT training improves detection of lung nodules, especially the part-solid ground-glass nodules. Detection of nodules adjacent to branching vessels and the posterior mediastinal lungs is difficult even for fellowship-trained radiologists.

PURPOSE: Oncologic imaging in the emergency department (ED) is frequently encountered, including non-acute scans known as "metastatic workups" or "staging" (referred to as "cancer staging computed tomography (CT) exams"). This study examines the impact of oncologic staging CT exams on ED imaging turnaround time (TAT), defined as the time from the end of the CT exam to a final signed radiologist report, as well as order to scan completion time. METHODS: A retrospective review was conducted of all adult patients presenting to an urban, quaternary academic medical center ED from February 2016 to September 2017, who had CT imaging ordered, performed, and interpreted in the ED imaging department. CT exams containing institution-specific cancer descriptors were included. After excluding all acute exams, cancer staging CT exams were compared to a matched cohort of non-oncologic ED CT exams to evaluate median TAT and order to scan completion time using a log transformed multivariable linear regression. RESULTS: Adjusting for age and CT body part, cancer staging CT exams were associated with an independently statistically significant increased median log TAT compared to non-oncologic ED CT exams (114.5 min [IQR 112] versus 69 min [IQR 67], respectively, pâ¯<â¯.0001) and an independently statistically significant increased median log initial order to scan completion time (166â¯min [IQR: 89] vs 119â¯min [IQR: 93], pâ¯<â¯.0001). CONCLUSION: Oncology patients receiving non-acute metastatic workup scans in the ED have a significantly longer TAT compared to non-oncologic ED CT exams as well as longer order to scan completion times.

PURPOSE: The aim of this study was to assess the prevalence of appropriate neuroimaging on the basis of the ACR Appropriateness Criteria among pediatric patients presenting after head trauma to a level I emergency department. METHODS: A retrospective emergency department record review was performed for patients <18 years of age undergoing head CT or MRI for the indication "head trauma" between January 2013 and December 2014. Clinical history and symptoms were compared with the ACR Appropriateness Criteria; the indication was deemed appropriate for ratings of ≥7. Patients were analyzed by age, gender, presentation, imaging obtained, follow-up, treatment, and outcomes. RESULTS: Among 207 patients, 120 (58%) were imaged with CT and 107 (52%) with MRI; 20 patients underwent both CT and MRI. One hundred eighty-seven patients (90.3%) were appropriately imaged, with 90.0% of CT studies (108 of 120) deemed appropriate and 91.6% of MRI studies (98 of 107) deemed appropriate. Younger patients were more likely to be inappropriately imaged with CT or MRI than older patients (P = .02 and P < .01, respectively). Patients undergoing CT were older (mean age 9.9 ± 5.8 years) and more likely to be male (85.2%) than those undergoing MRI (5.6 ± 5.6 years and 55.1%, respectively) (P < .01 and P < .001, respectively). The diagnostic yield of positive imaging findings for intracranial trauma was significantly lower in the MRI group (P < .01), and patients undergoing MRI were significantly more likely to return to baseline with conservative management (P < .01). CONCLUSIONS: Most pediatric patients undergoing neuroimaging for head trauma did so appropriately per ACR guidelines and had symptom resolution with conservative management. The minority not imaged appropriately represent a target for quality improvement efforts.

PURPOSE: To assess the prevalence of appropriate imaging among emergency department (ED) patients with low back pain. METHODS: Our level-1 ED records were retrospectively searched for patients with a chief compliant of "low back pain" from January to April 2013. Of 624 patients, 100 were randomly selected and analyzed for their demographics, presentation, imaging, treatment, and outcomes. The study indication for imaging was compared with the ACR Appropriateness Criteria, and the indication was deemed appropriate if it received a rating of ≥5. RESULTS: The mean age of the study population was 48 years (50% women, 50% men). The majority presented with acute or acute on chronic low back pain (94 patients), and half had a precipitating event (50 patients). A total of 28 (28%) patients underwent imaging in the ED; 24 (24%) had outpatient imaging; 54 (54%) had neither ED nor outpatient imaging. In all, 96% (27 of 28) of patients imaged in the ED, and 96% (23 of 24) imaged as outpatients, were appropriately imaged. Of patients who did not undergo imaging, 96% (52 of 54) were appropriately not imaged. A total of 76 patients (76%) had follow-up after discharge: of these, 42 (55%) had resolution or return of pain to baseline with conservative management; 18 (24%) had improvement with intervention (epidural steroid injection or kyphoplasty); 8 (10%) improved with surgery; and 8 had persistent pain (11%). CONCLUSIONS: The majority of patients presenting to the ED with low back pain did not undergo imaging. The vast majority of those who underwent imaging were appropriately imaged, based on the ACR Appropriateness Criteria.

The six competency domains required by the Accreditation Council for Graduate Medical Education (ACGME) have led to a proliferation of measurement tools, assessment methods, and all forms of data from paper to electronic. The need exists to develop a standardized electronic (e)-portfolio to provide the aggregate data to improve education and patient care. This process requires a sound methodology using XML metadata to allow portability of e-portfolio data. We surveyed publicly available metadata and developed an e-portfolio system for the Henry Ford Hospital General Surgery Residency Program. Based on our implementation of e-portfolios for 70 physicians, we call upon the ACGME, the Residency Review Committees, and the American Board of Medical Specialties to establish a method to formalize and develop a standard for residency competency metadata. Using an approach similar to that of our study can streamline data and lead to improved medical education and ultimately better patient care.

OBJECTIVES: In most institutions, planning computed tomography (CT) scans are not interpreted by diagnostic radiologists. The purpose of this analysis was to determine the percentage of cases in which a previously undetected radiographic finding was found on review of CT simulation images by diagnostic radiology. METHODS: At the Henry Ford West Bloomfield Center, CT simulations are prospectively interpreted by diagnostic radiologists and a formal report is generated. CT simulation scan reports of 332 consecutive breast cancer patients from 2000 to 2006 were reviewed. The percentage of these reports in which a previously undetected abnormality was noted on the planning CT was determined. Prior and subsequent diagnostic CT scans were also reviewed to determine the clinical relevance of these diagnostic abnormalities. RESULTS: Of 332 patients with CT simulations for breast cancer treatment planning, 52 patients (16%) had a newly detected abnormality noted. Of these, 31 patients (or 60% of the abnormal findings) were deemed by diagnostic radiology to have potentially significant findings (e.g., "can not exclude metastatic disease"), and a follow-up CT or magnetic resonance imaging scan was recommended. Abnormalities in this category included previously undetected lung nodules, liver lesions, kidney/adrenal lesions, and sclerotic bony lesions. On follow-up, however, to date, these findings have demonstrated no clinical significance, although further follow-up is needed in many patients. CONCLUSIONS: In this study, a significant proportion of breast cancer patients undergoing CT planning studies were diagnosed with potential abnormalities for which follow-up was recommended by diagnostic radiology. To date, these findings have not been clinically relevant, though further follow-up is needed in many of the patients. Thus, in cases of clinical uncertainty, a diagnostic radiologist should be consulted and follow-up imaging obtained if necessary.

BACKGROUND: A requirement for all Accreditation Council for Graduate Medical Education (ACGME) approved residencies is the provision of "an opportunity for residents to participate in research." To comply with this requirement, most training programs encourage their residents to conduct research and to report their results. Few guidelines exist, however, for assessing the efficacy of the presentations. The goal of this pilot study was to develop a valid, one-page scoring rubric to be used during oral resident research presentations. Such a scoring rubric will facilitate acceptable agreement among faculty raters. METHODS: Content validity was addressed by adhering to the Standards for Educational and Psychological Testing. A one-page, five-domain, behaviorally worded scoring rubric was developed. Inter-rater reliability was derived and three ACGME General Competencies were also addressed within the rubric. RESULTS: The initial scoring rubric was tested with 11 resident oral presentations. The inter-rater reliability was 0.56 using Cronbach's alpha. The rubric was modified and the scale restricted to a 3-point scale. It was then tested with 17 additional presentations, which were independently rated by two general surgery faculty members. Cronbach's Alpha increased to 0.61. CONCLUSIONS: An objective method to evaluate a resident's oral research presentation has been successfully piloted. This content valid rubric possesses good inter-rater reliability according to established guidelines. Clearly defined behaviors have been outlined within the rubric. Program directors will have psychometrically sound evidence for the ACGME. Future research will address generalizability and concurrent validity using other types of resident assessment data.
