Diversity Within the Most Competitive Internal Medicine Fellowships: Examining Trends from 2008 to 2018.

BACKGROUND: Prior studies have demonstrated the importance of diversity among physicians. Identifying trends in diversity within the most competitive internal medicine (IM) fellowships can guide focused efforts to address barriers to equal representation. OBJECTIVE: To examine the racial and gender composition of resident applicants and accepted fellows to the top five most competitive IM specialties. DESIGN: Survey data from the AAMC, JAMA, and NRMP were obtained. Fisher's exact tests were conducted to compare differences in representation between fellows in the most competitive specialties, resident applicants into those specialties, and categorical IM residents. Linear regression was used to analyze trends within each group. PARTICIPANTS: Categorical IM residents and fellows at ACGME-accredited M.D. programs in the USA. MAIN MEASURES: Proportion of each population by gender and race/ethnicity KEY RESULTS: Women saw an increase in representation among accepted fellows to the most competitive IM fellowships from 2008 to 2013 (+ 4.4%, p < 0.011), but the trend has since plateaued at a level (34%) significantly lower than their representation among IM residents (43%, p < 0.001). Black representation among accepted fellows (4.6%) has been increasing from 2008 to 2018 (+ 1.2%, p = 0.001), but is still significantly lower than their representation among IM residents (5.6%, p < 0.001). Hispanic resident applicant and fellow representation have seen minimal change. CONCLUSION: Despite trends towards better representation among women and underrepresented minorities (URMs) among fellows in the most competitive IM specialties from 2008 to 2013, there has been a stagnation in both gender and racial diversity over the past 5 years. Further efforts must be undertaken to address barriers to entry and advocate for better representation of women and URMs in fellowship programs.

Radial haemostasis is facilitated with a potassium ferrate haemostatic patch: the Statseal with TR Band assessment trial (STAT).

AIMS: Haemostasis is a limiting factor for discharge after uncomplicated transradial procedures. The purpose of this study was to determine whether a potassium ferrate haemostatic patch (PFHP) could serve as an adjunct to the air-bladder TR Band (TRB) to facilitate implementation of a rapid deflation protocol. METHODS AND RESULTS: This was a prospective multicentre randomised controlled trial comparing radial haemostatic protocols. Deflation of the TRB was attempted at 40 minutes with PFHP and at 120 minutes without the PFHP. The primary outcome was time to full deflation of the TRB with haemostasis. At four US sites, 180 patients were enrolled after receiving a minimum of 5,000 units of unfractionated heparin or bivalirudin. Interventions comprised 30% of procedures. Successful TRB deflation occurred at 43±14 minutes with PFHP and 160±43 minutes without PFHP (p<0.001). Minor haematomas occurred in nine (10.3%) of the TRB patients and 16 (17.2%) of the PFHP patients (p=0.20). Radial artery occlusion occurred in 2% of patients in the PFHP group (p=NS). Outpatients randomised to PFHP were discharged 51±83.5 minutes earlier than control. CONCLUSIONS: The PFHP haemostatic patch facilitated early deflation of the TRB with a non-significant increase in forearm haematomas. Use of the PFHP may improve patient throughput and allow earlier discharge following transradial procedures.

Prevalence, indications and management of balloon uncrossable chronic total occlusions: Insights from a contemporary multicenter US registry.

BACKGROUND: Balloon uncrossable lesions can be challenging to treat, requiring specialized techniques and equipment. METHODS: We examined the prevalence, clinical and angiographic characteristics, management and procedural outcomes of balloon uncrossable lesions in a multicenter chronic total occlusion (CTO) percutaneous coronary intervention (PCI) registry. RESULTS: Between 2012 and 2016, 718 CTO PCIs (in which the occlusion was successfully crossed with a guidewire) were performed in 701 patients at 11 US centers. Mean age was 65.6 ± 10 years and 84% of the patients were men. Balloon uncrossable lesions represented 9% of all CTOs. Balloon uncrossable CTOs had more moderate/severe calcification (82% vs. 52%, P < 0.0001), moderate/severe tortuosity (61% vs. 35% P < 0.0001) and higher J-CTO score (2.95 ± 1.32 vs. 2.43 ± 1.23, P = 0.005) as compared with the remaining lesions. Technical and procedural success was significantly lower for balloon uncrossable lesions (90.5% vs. 98.3%, P < 0.0001 and 88.9% vs. 96.6% P = 0.004), respectively, but the incidence of major adverse events was similar (1.6% vs. 2.2%, P = 0.751). Balloon uncrossable lesions required longer procedure (208 [interquartile range: 135, 258] vs. 135 [94, 194] min, P < 0.0001) and fluoroscopy (77 [52, 100] vs. 45 min [27, 75], P < 0.0001) time. Techniques used to treat balloon uncrossable lesions included balloon-assisted microdissection (23%), excimer laser atherectomy (18%), and rotational atherectomy (16%). Excimer laser atherectomy and balloon-assisted microdissection were associated with the highest technical and procedural success rates. CONCLUSIONS: Balloon uncrossable CTOs are common, are associated with high rates of technical failure, and require specialized techniques for successful treatment. © 2016 Wiley Periodicals, Inc.

Comparison of procedural success and long-term outcomes of stent thrombosis in coronary bypass grafts versus native coronary arteries.

Percutaneous coronary intervention within bypass grafts accounts for a significant percentage of total interventions. Bypass graft interventions are associated with an increased risk for stent thrombosis (ST), a condition that leads to significant morbidity and mortality. Despite this, the procedural characteristics and long-term outcomes of patients with bypass-graft ST have not been reported. The aim of the present study was to evaluate the procedural success and long-term outcomes of patients presenting with ST of coronary bypass grafts. Clinical and procedural characteristics of 205 ST cases at 5 academic hospitals were reviewed. Long-term mortality and major adverse cardiovascular events (stroke, reinfarction, and revascularization) were ascertained through review of medical records and the Social Security Death Index. Kaplan-Meier analysis was used to determine the association between ST in a bypass graft and long-term outcomes. Thirteen patients (6%) in the cohort presented with ST of a coronary bypass graft. Patients with bypass-graft ST had less severe presentations with a lower proportion of ST-segment elevation myocardial infarction (23% vs 69%, p <0.001). Despite this, ST of a bypass graft was associated with a trend toward reduced postprocedural Thrombolysis In Myocardial Infarction (TIMI) flow grade (p = 0.09), leading to lower angiographic (58% vs 92%, p <0.001) and procedural (62% vs 92%, p <0.001) success. After multivariate adjustment, bypass-graft ST was associated with increased long-term mortality (hazard ratio 3.3, 95% confidence interval 1.0 to 10.7) and major adverse cardiovascular events (hazard ratio 2.7, 95% confidence interval 1.1 to 6.9). In conclusion, ST in coronary bypass grafts is associated with reduced angiographic and procedural success as well as increased long-term major adverse cardiovascular events compared to ST in native coronary vessels.

Accurate ECG diagnosis of atrial tachyarrhythmias using quantitative analysis: a prospective diagnostic and cost-effectiveness study.

UNLABELLED: Quantitative ECG Analysis. INTRODUCTION: Optimal atrial tachyarrhythmia management is facilitated by accurate electrocardiogram interpretation, yet typical atrial flutter (AFl) may present without sawtooth F-waves or RR regularity, and atrial fibrillation (AF) may be difficult to separate from atypical AFl or rapid focal atrial tachycardia (AT). We analyzed whether improved diagnostic accuracy using a validated analysis tool significantly impacts costs and patient care. METHODS AND RESULTS: We performed a prospective, blinded, multicenter study using a novel quantitative computerized algorithm to identify atrial tachyarrhythmia mechanism from the surface ECG in patients referred for electrophysiology study (EPS). In 122 consecutive patients (age 60 ± 12 years) referred for EPS, 91 sustained atrial tachyarrhythmias were studied. ECGs were also interpreted by 9 physicians from 3 specialties for comparison and to allow healthcare system modeling. Diagnostic accuracy was compared to the diagnosis at EPS. A Markov model was used to estimate the impact of improved arrhythmia diagnosis. We found 13% of typical AFl ECGs had neither sawtooth flutter waves nor RR regularity, and were misdiagnosed by the majority of clinicians (0/6 correctly diagnosed by consensus visual interpretation) but correctly by quantitative analysis in 83% (5/6, P = 0.03). AF diagnosis was also improved through use of the algorithm (92%) versus visual interpretation (primary care: 76%, P < 0.01). Economically, we found that these improvements in diagnostic accuracy resulted in an average cost-savings of $1,303 and 0.007 quality-adjusted-life-years per patient. CONCLUSIONS: Typical AFl and AF are frequently misdiagnosed using visual criteria. Quantitative analysis improves diagnostic accuracy and results in improved healthcare costs and patient outcomes.
