Personal ultrasound imager: abdominal aortic aneurysm screening.

BACKGROUND: Miniaturized ultrasonographic machines (2.5-MHz curved-array transducer connected to a compact 2.6-kg console), termed personal ultrasound imagers (PUIs), may enable detection of occult abdominal aortic aneurysms (AAAs). OBJECTIVES: Our goals were to determine whether a PUI is capable of screening for AAAs and to compare the results with an established screening examination with standard echocardiography (SE). METHODS: One hundred twenty-five patients (aged >70 years) with hypertension who were referred for transthoracic echocardiography were enrolled. After SE, a focused screening with a PUI examination was performed by a blinded sonographer. An AAA was defined as a focal enlargement of the aorta >30 mm. Results and the length of time to image the aorta were compared for both tests. RESULTS: We studied 64 men and 61 women (aged 76.8 +/- 5 years; mean blood pressures: systolic 145.7 +/- 18 and diastolic 78.6 +/- 10; body surface area 1.9 +/- 0.2 m(2)). The mean time for SE was 2.9 +/- 1.5 minutes and for the PUI examination was 4.6 +/- 2.3 minutes. By using SE as the gold standard, the sensitivity and specificity of the PUI were 91% and 96%, respectively. The positive predictive value of the PUI was 71%, and the negative predictive value was 99%. CONCLUSION: A PUI can be used to screen for occult AAAs as an extension of the physical examination. Results are comparable to an established screening strategy that uses more expensive, nonportable echocardiographic equipment.     

Abdominal aortic aneurysm screening during transthoracic echocardiography in an unselected population.

OBJECTIVE: We sought to investigate the echocardiographic prevalence of abdominal aortic aneurysm (AAA) in an unselected group of patients referred for regular transthoracic echocardiography (TTE). METHODS: Prospectively, during a 3-month period, a limited ultrasound examination of the infrarenal aorta was performed. AAA was defined as a diameter of 30 mm or more. RESULTS: The abdominal aorta could be visualized in 742 patients. The prevalence of AAA was 4.6%. AAA prevalence increased with age, especially in men. In 34 patients AAA was unknown and aortic diameters exceeded 50 mm in 4 patients. Two underwent elective but urgent operation. Patients with AAA were older and had an increased ascending aorta diameter, larger left ventricular dimensions, higher left ventricular mass index, and lower ejection fraction. CONCLUSION: AAA is prevalent in patients referred for regular TTE. Routine rapid screening of the abdominal aorta during TTE is beneficial and should, therefore, be part of a standard TTE examination for patients older then 50 years.     

A curricular initiative for internal medicine residents to enhance proficiency in internal jugular central venous line placement

OBJECTIVE: To determine the feasibility, efficacy, and outcomes of teaching Internal Jugular (IJ) central venous line placement (CVLP) to internal medicine residents in a hands-on training experience with adult patients. SUBJECTS AND METHODS: Data were obtained from 47 residents during their 3-year residency program through questionnaires and a proprietary system that tracks resident procedures. Twenty-five postgraduate year (PGY) 2 residents at the Mayo Clinic in Rochester, Minn, were assigned to IJ-CVLP training in the cardiac catheterization laboratory from January 2001 to June 2001. Their experience, analyzed immediately after training and at completion of residency, was compared with that of 22 PGY-2 residents in the same class who were not assigned to IJ-CVLP training. RESULTS: The median Likert scores of the residents' self-reported perception of independence in IJ-CVLP increased from 3.0 (mean +/- SD score, 2.8+/-1.4) before the intervention to 5.0 (4.4+/-0.9) after the intervention (P<.001, signed rank test). At graduation, trained residents had performed more IJ-CVLPs than the control residents (mean +/- SD, 17.8+/-8.4 vs 9.8+/-6.3, respectively; P<.001). Residents who received IJ-CVLP training, compared with those who did not, showed a significant increase in the mean percentage of IJ-CVLPs performed independently between PGY-1 (2.2%) and PGY-3 (31.2%) (P=.008). CONCLUSIONS: Training internal medicine residents to perform IJ-CVLP is feasible in the cardiac catheterization laboratory with supervision from an attending cardiologist. Trained residents performed significantly more IJ-CVLPs independently during their third year compared with their first year of training. We believe this initiative may be implemented successfully in graduate medical education curriculums.

Quantification of training in obstetrical ultrasound: a study of family practice residents.

This study was done to determine how rapidly physicians in training could become competent in performing obstetrical ultrasound for the purposes of routine evaluations (i.e., the standard examination as defined by AIUM). The scan measurements and results of organ surveys of 12 family medicine residents were compared with the results obtained by faculty members experienced in obstetrical ultrasound. Residents rapidly became proficient in biometry. The mean menstrual age calculated from BPD, AC, HC, and FL differed from faculty values by 0.381 weeks after residents had performed 40 supervised scans. Organ survey success rates demonstrated similar high concordance between resident and faculty scans.     

Changes in internal medicine residents' attitudes about resuscitation after cardiac arrest over a decade

Background

Resident physicians' beliefs about cardiopulmonary resuscitation (CPR) may impact their communication with patients about end-of-life care. We sought to understand how these perceptions and experiences have changed in the past decade because both medical education and American society have focused more on this domain.

Method

We surveyed 2 internal medicine resident cohorts at a large academic medical center in 1995 and 2005. Residents were asked of their beliefs about survival after CPR, perceived patient understanding, and regret after attempted resuscitation. Residents in 2005 reported more numerical experience with CPR. Current internal medicine residents are more optimistic than the 1995 cohort about survival after an inpatient cardiac arrest. They believe that far fewer patients and families understand resuscitation but report less regret about attempting to resuscitate patients.

Conclusions

These pilot data reveal potential changes in the attitudes of resident physicians toward CPR. The perceived poor understanding among decision makers calls into question the standard of informed consent. Despite this, residents report less regret leading one to ask what factors may underlie this response.     

Abdominal ultrasound examination training using an ultrasound phantom and volume navigation system

Purpose

The purpose of this study was to examine the effects of using an ultrasound phantom (ECHOZY) and a volume navigation system (Vnavi) in abdominal ultrasonography training for young residents.

Methods

Nine third-year residents underwent abdominal ultrasonography training: controls, comprising five residents; and the ECHOZY + Vnavi group, comprising four residents. Residents were trained in abdominal ultrasound examinations using both educational videos and hands-on clinical training. The ECHOZY + Vnavi group also received training using an ultrasound phantom and volume navigation system. The time needed for abdominal ultrasound examination was calculated at 4 months (early), 8 months (middle), and 12 months (late) after starting training. The ability of each resident to visualize 20 abdominal structures on normal patients was also evaluated retrospectively.

Results

In the early period, the ECHOZY + Vnavi group needed significantly longer to complete examinations than controls (545 ± 125 s versus 392 ± 81 s, p < 0.01), but showed significantly better ability scores (17.5 ± 0.6 versus 13.4 ± 1.1, p < 0.05). Both these differences disappeared by the middle period (338 ± 107 s versus 259 ± 130 s and 17.8 ± 0.5 versus 16.0 ± 0.7).

Conclusion

In spite of longer examination times, training residents in abdominal ultrasonography using an ultrasound phantom and volume navigation system may be useful in the early period.

     

Teaching Patient Empathy The ED Visit Program

OBJECTIVE: Residency programs only are not challenged with developing competent emergency clinicians, but should strive to develop caring, empathetic, and community-minded physicians. An exercise was designed to help residents experience emergency department (ED) visits from the patient's perspective. METHODS: This study occurred in emergency medicine residency program at an urban teaching institution with an annual ED census of 94,000. On the first day of residency orientation, each resident was given a clinical scenario and registered through triage into the ED. Nurses were blinded to the study. The study concluded when the examining physician entered the exam room. Residents were then presented with a simulated bill based on their scenario. Residents completed a survey initially and at six months. Survey ratings were measured using a 100-mm visual analog scale (VAS) (0 = not at all; 100 = a great deal). RESULTS: Twenty-five residents participated over two years. Sixty-four percent had never been an ED patient before. Median length of stay was 139 minutes. This exercise was found to improve resident empathy for patients on initial survey, 66 mm (range 16-71), and at follow-up, 66 mm (range 23-91). Residents found the exercise useful both initially, 50 mm (range 4-86), and at follow-up, 49 mm (range 15-81). Ninety-two percent of the residents thought the goals of the exercise had been met. Residents also stated the study changed their approach to patient care (45 mm, range 4-76) and made them a better physician (49 mm, range 5-80). CONCLUSIONS: The ED visit study enhanced patient empathy within residents and was useful in improving patient care attitude.     

A Randomized Controlled Trial Using Insinuated Standardized Patients to Assess Residents' Domestic Violence Skills Following a Two-Hour Workshop

Background: Residents feel inadequately trained to treat domestic violence victims.

Purpose: The purpose was to assess clinical skills of residents participating in a domestic violence workshop.

Methods: Twenty-seven internal medicine residents were randomized to receive one of two workshops (domestic violence or control workshop). Standardized patients were trained to two domestic violence cases (depressed; injured). The two cases were randomized and insinuated into each resident's continuity clinic at either 1 to 3 months or more than 3 months after the workshops.

Results: The domestic violence workshop residents did not identify the standardized patients as domestic violence victims any more often than residents participating in the control workshop; 16/25 (64%) versus 13/23 (56%), p = .86. However, domestic violence workshop residents were more likely to score 75% or higher on the domestic violence checklist items compared to control workshop residents; 9/25 (36%) versus 2/23 (9%), p = .04.

Conclusions: Once a standardized patient was identified in clinic as a domestic violence victim, domestic violence workshop participating residents demonstrated better clinical skills than a control group.     

Experience with the Endologix Powerlink endograft in endovascular repair of abdominal aortic aneurysms with short and angulated necks

Endovascular aortic aneurysm repair (EVAR) for anatomically suitable abdominal aortic aneurysms (AAAs) has gained wide acceptance in the past decade, and EVAR for anatomically challenging or unsuitable AAAs such as short and angulated neck AAAs has become a hotly debated subject. The objective of this study is to summarize the unique experience of EVAR for short / angulated neck AAAs with Powerlink unibody bifurcated stent-graft. Data were retrospectively analyzed from 519 patients in our single unit from February 1999 to December 2007 who underwent EVAR using the Powerlink endograft, and had short or angulated necks. Short neck was defined as < or = 15 mm for the infrarenal neck length, and it was divided into 2 groups: Group A (short neck), 54 cases with the length 11 to 15 mm; and Group B (very short neck), 26 cases with the length < or = 10 mm. Angulated neck of 37 cases which was defined as > or = 60 degrees angulation between the longitudinal axis of infrarenal aorta and the aneurysm. The unique strategy of treating short / angulated neck AAAs is to build up the endoluminal exclusion system from the native aortic bifurcation to the renal artery level with suprarenal fixation. The Powerlink unibody bifurcated stent graft was implanted anatomically fixed on the aortic bifurcation and a long suprarenal cuff was built up to the renal arteries. A Palmaz stent can be used for proximal fixation and sealing enhancement in the most challenging necks. The follow-up imaging was performed at 1 month, 6 months, and yearly thereafter. The technical success rate was 97.4% (114/117). Intraoperative complications included 3 conversions due to delivery access problems, 6 proximal type I endoleaks, and 5 type II endoleaks. The 30-day mortality was 1.7% (2/117). The 2.6-year follow-up showed 4 (3.4%) proximal type I endoleaks, which were revised with proximal cuff and/or Palmaz stent. Limb occlusion occurred in 2 cases, and the total re-intervention rate was 5.3%. Three (2.6%) type II endoleaks were left in observation. There were 3 (2.6%) partial renal infarctions, no stent-graft distal migration, and no post-EVAR ruptures. Our experience demonstrates that building up the endoluminal exclusion system from the abdominal aortic bifurcation to the renal artery level using the Powerlink fully supported unibody bifurcated stent-graft with a long suprarenal cuff, and a Palmaz stent when needed, proved safe and effective in treating AAAs with short and angulated necks.     

Accuracy of emergency medicine ultrasound in the evaluation of abdominal aortic aneurysm

This study assesses the accuracy of Emergency Medicine (EM) residents in detecting the size and presence of abdominal aortic aneurysms (AAAs) using EM ultrasound (EUS) compared to radiology measurement (RAD) by computed tomography (CT) scan, magnetic resonance imaging (MRI), angiography, or operative findings. There were 238 aortic EUS performed from 1999–2000; 36 were positive for AAA. The EUS finding of “AAA” had a sensitivity of 0.94 (0.86–1.0 95% confidence interval [CI]) and specificity of 1 (0.98–1.0 95% CI). Mean aortic diameter among patients with AAA identified by EUS was 5.43 ± 1.95 cm and by RAD was 5.35 ± 1.83 cm. The mean absolute difference between EUS and RAD diameters was 4.4 mm (95% CI 3.7–5.5 mm). Regression of EUS on RAD diameters is strongly correlated, with R² = 0.92. EM residents with appropriate training can accurately determine the presence of AAA as well as the maximal aortic diameter.     

Internal Medicine Residents’ Perspectives on Effects of 2011 ACGME Work Hour Regulations on Patient Care

Background: The Accreditation Council for Graduate Medical Education (ACGME) introduced new work hour limitations in July 2011. Purposes: The aim is to assess internal medicine residents’ perspectives on the impact of these limitations on their ability to discharge patient care duties. Methods: An anonymous survey was administered to 158 medicine residents in an urban university-affiliated internal medicine residency program. Residents’ perspectives on various aspects of patient care were recorded on a 5-point Likert-type scale. Results: The response rate was 62%. The majority of residents (80%) agreed that patients had adequate continuity of care. Most residents agreed that they had enough time to follow up on consult notes (64% agreed) and investigations (80% agreed) daily. Most PGY-1 residents (59%) reported having enough time to prepare sign-outs. Most (60%) residents felt that reducing handoffs would improve patient care. Conclusions: Most residents believe that the new work hour limitations would continue to uphold patient safety, but handoffs in care must be restricted.     

Strain estimation in abdominal aortic aneurysms from 2-D ultrasound

The rupture risk of abdominal aortic aneurysms (AAAs) is routinely inferred from the maximum diameter of the AAA. However, clinical experience indicates that this criterion has poor accuracy and that noninvasive assessment of the elastic properties of the vessel might give better correspondence with the rupture risk. We have developed a method for analysis of circumferential strain in AAAs from sequences of cross-sectional ultrasound B-mode images. The algorithm is fast, semiautomatic and well-suited for real-time applications. The method was developed and evaluated using data from 10 AAA patients. The preliminary results demonstrate that the method is sufficiently accurate and robust for clinically acquired data. An important finding is that local strain values may exceed the circumferential average strain significantly. Furthermore, the calculated strain shows no apparent covariation with the diagnosed diameter. This implies that the method may give new and essential information on the clinical condition of the AAA.     

Office-based ultrasound screening for abdominal aortic aneurysm

Objective

To assess the efficacy of an office-based, family physician–administered ultrasound examination to screen for abdominal aortic aneurysm (AAA).

Design

A prospective observational study. Consecutive patients were approached by nonphysician staff.

Setting

Rural family physician offices in Grand Forks and Revelstoke, BC.

Participants

The Canadian Society for Vascular Surgery screening recommendations for AAA were used to help select patients who were at risk of AAA. All men 65 years of age or older were included. Women 65 years of age or older were included if they were current smokers or had diabetes, hypertension, a history of coronary artery disease, or a family history of AAA.

Main outcome measures

A focused “quick screen,” which measured the maximal diameter of the abdominal aorta using point-of-care ultrasound technology, was performed in the office by a resident physician trained in emergency ultrasonography. Each patient was then booked for a criterion standard scan (ie, a conventional abdominal ultrasound scan performed by a technician and interpreted by a radiologist). The maximal abdominal aortic diameter measured by ultrasound in the office was compared with that measured by the criterion standard method. The time to screen each patient was recorded.

Results

Forty-five patients were included in data analysis; 62% of participants were men. The mean age was 73 years. The mean pairwise difference between the office-based ultrasound scan and the criterion standard scan was not statistically significant. The mean absolute difference between the 2 scans was 0.20 cm (95% CI 0.15 to 0.25 cm). Correlation between the scans was 0.81. The office-based ultrasound scan had both a sensitivity and a specificity of 100%. The mean time to screen each patient was 212 seconds (95% CI 194 to 230 seconds).

Conclusion

Abdominal aortic aneurysm screening can be safely performed in the office by family physicians who are trained to use point-of-care ultrasound technology. The screening test can be completed within the time constraints of a busy family practice office visit. The benefit of screening for AAA in rural patients might be great if local diagnostic ultrasound service and emergent transport to a vascular surgeon are not available.     

Abdominal circumference: a single measurement versus growth rate in the prediction of intrapartum Cesarean section for fetal distress.

OBJECTIVE: The fetal abdominal circumference is the most sensitive ultrasound biometric measurement for predicting intrauterine growth restriction, which is associated with an increased risk of intrapartum fetal distress. We sought to evaluate and compare whether a third-trimester ultrasound measurement of abdominal circumference made within 1 week prior to delivery better predicts operative delivery for fetal distress when compared with the growth velocity of the abdominal circumference in the third trimester. METHODS: Retrospective analysis was carried out of prospectively collected ultrasound data on 117 patients with singleton gestations who had had at least two ultrasound assessments performed less than 6 weeks apart in the third trimester, with the last ultrasound performed within 1 week prior to delivery. The abdominal circumference value of the last ultrasound prior to delivery was placed into one of three categories: < or = 5% centile, > 5 to < or = 10% centile and > 10% centile for gestational age. The growth velocity of the abdominal circumference per week was placed into one of three categories: < or = 5 mm/week, 6-10 mm/week and > or = 11 mm/week. The chi-squared test was used to compare differences between the incidence of fetal distress between the groups. RESULTS: The incidences of Cesarean section for fetal distress in relation to a single measurement of the abdominal circumference were: < or = 5% centile, 8/23 (35%); > 5 to < or = 10% centile, 3/12 (25%); > 10% centile, 8/81 (10%) ( P < 0.05). The incidences of Cesarean section for fetal distress with the three abdominal circumference growth velocities were: < or = 5 mm/week, 9/55 (16%); 6-10 mm/week, 4/11 (36%); > or = 11 mm/week, 8/51 (16%) ( P = 0.9401). CONCLUSION: A single measure of the fetal abdominal circumference made within 1 week prior to delivery is superior to an assessment of growth rate of the fetal abdomen in the third trimester in discriminating patients who require Cesarean section for fetal distress.     

Noninvasive measurement of abdominal aortic aneurysms in intact mice by a high-frequency ultrasound imaging system

Mouse models of abdominal aortic aneurysm (AAA) have been commonly used in many laboratories for studying molecular mechanisms of AAA formation and development, as well as for testing novel therapeutic agents in the treatment of AAA. However, because of the small size of the animal, the quantification and characterization of AAA development and progress is difficult, time-consuming and requires the sacrifice of the experimental animals. We report here a noninvasive method to detect and measure AAA in mice using a high-frequency ultrasound (US) imaging system specifically designed for microimaging of the mice (Vevo 660; VisualSonics, Toronto, ONT, Canada). A total of 21 male apolipoprotein-E-deficient mice were chronically infused with angiotensin II (1.44 mg/kg daily) for 28 days to induce AAA formation. A 2-D echo image of the abdominal aorta was acquired at longitudinal and transverse planes, followed immediately by post mortem dissection of the abdominal aorta for direct measurements. The US images clearly showed a bulge-like expansion localized specifically in the suprarenal region of the abdominal aorta, with a shape strikingly similar to that of the aorta dissected post mortem. In addition, the US images can also provide measurements of the luminal diameter and wall thickness of the abdominal aorta. The average dimensions of the abdominal aorta were not significantly different between the US and post mortem measurements, nor between the transverse and longitudinal US images. The different types of the measurements are also highly correlated with each other, with a linear correlation (r) between 0.7 and 0.9. Thus, we have established and validated a novel application to noninvasively measure AAA development and progress in a mouse model using a high-frequency US imaging system that has the advantages of low cost, rapid imaging speed, reproducibility and high resolution, and makes repeated monitoring of the progress of AAA development over a time-course possible.     

Standardization of outcome measures in clinical trials of pharmacological treatment for abdominal aortic aneurysm

An abdominal aortic aneurysm (AAA) is a common aortic wall disease with an increased prevalence in the elderly population (4–8% for those aged >65 years). Many AAAs are slow growing and remain insidious. Current standard of care for patients with small AAAs (<49 mm) is surveillance, with interventional therapy (open surgical repair or endovascular aneurysm repair) recommended for large (>50–55 mm), rapidly growing (>10 mm/year) or symptomatic AAAs. Although open surgical repair or endovascular aneurysm repair are effective, significant short- and long-term postoperative morbidity and mortality occurs. Currently, there is no pharmacological treatment specific for AAA; the need for the development of targeted pharmacological therapies based on clinically relevant and feasible outcomes acceptable to the medical community, regulatory agencies and third-party payers is high. A consensus on such end points will be critical to accelerating the development of pharmacological agents to prevent formation, arrest the expansion and reduce the rupture risk of AAA.

Ultrasonographic identification and semiquantitative assessment of unloculated pleural effusions in critically ill patients by residents after a focused training

Purpose

Chest ultrasonography is currently a required element to achieve competence in general critical care ultrasound (GCCUS) which should be part of the training of every intensivist. We sought to assess the ability of resident novices in ultrasonography to identify and quantify unloculated pleural effusions in ICU patients after a limited training program.

Methods

A total of 147 patients (mean age, 62 ± 17 years; simplified acute physiology score II, 35 ± 15; 78 % ventilated) with a suspected pleural effusion underwent a thoracic ultrasonography performed successively by a recently trained resident novice in ultrasound and by an experienced intensivist with expertise in GCCUS, considered as reference. Ultrasonographic examinations were performed randomly and independently. In the presence of a pleural effusion, the maximal interpleural distance was measured at the thoracic base.

Results

Residents performed a mean of 15 ± 9 examinations. Agreement between residents and experienced intensivists for the diagnosis of left- and right-sided pleural effusions was good to excellent [kappa 0.74 (95 % CI 0.63–0.85) and 0.86 (95 % CI 0.78–0.94), respectively)]. Agreement for the measurement of left and right maximal interpleural distance was excellent (intraclass concordance coefficient, 0.86 [95 % CI 0.77–0.91] and 0.85 [95 % CI 0.75–0.90], respectively). Mean bias for left and right interpleural distance was ?0.3 mm (95 % CI ?2.4, 1.8 mm) and ?1.2 mm (95 % CI ?3.4, 1.1 mm), respectively.

Conclusions

After a focused training program, resident novices in ultrasound identify and quantify unloculated pleural effusions in ICU patients using chest ultrasonography with a good agreement with experts.     

Shared Decision Making in Common Chronic Conditions: Impact of a Resident Training Workshop

Problem: Physicians must be competent in several different kinds of communication skills in order to implement shared decision making; however, these skills are not part of routine medical student education, nor are they formally taught during residency training. Intervention: We developed a 1- and 2-hour workshop curriculum for internal medicine residents to promote shared decision making in treatment decisions for four common chronic conditions: diabetes, depression, hypertension, and hyperlipidemia. The workshops included a written case exercise, a short didactic presentation on shared decision-making concepts and strategies for risk communication, and two role-playing exercises focused on decision making for depression and hyperlipidemia treatment. Context: We delivered the workshop as a required component of the resident curriculum in ambulatory medicine. To evaluate the impact of the workshop, we used written course evaluations, tracked the use of the newly introduced Decision Worksheets, and asked preceptors to perform direct observation of treatment decision conversations. Outcome: Residents were involved in the development of the workshop and helped identify key content, suggested framing for difficult topics, and confirmed the need for the skills workshop. One hundred thirty internal medicine and medicine-pediatrics residents attended 8 workshops over a 4-month period. In written cases completed before the workshop, the majority of residents indicated that they would discuss medications, but few mentioned other treatment options or documented patients’ goals and preferences in a sample encounter note with a patient with new depression symptoms. Overall, most participants (89.7%) rated the workshop as excellent or very good, and 93.5% said that they would change their practice based on what they learned. Decision Worksheets addressing diabetes, depression, hyperlipidemia, and hypertension were available on a primary care-focused intranet site and were downloaded almost 1,200 times in the first 8 months following the workshops. Preceptors were able to observe only one consult during which one of the four topics was discussed. Lessons Learned: Internal medicine residents had considerable gaps in shared decision-making skills as measured in a baseline written exercise. Residents provided valuable contributions to the development of a Decision Worksheet to be used at the point of care. Participants rated the skills workshop highly, though interns rated the exercise more useful than PGY-2 and PGY-3 residents did. The Decision Worksheets were accessed often following the sessions; however, observing the Decision Worksheets in use in real time was a challenge in the resident-faculty clinic. Additional studies are warranted to examine whether the workshop was successful in increasing residents’ ability to implement skills in practice.
