Well-Being Parameters and Intention to Leave Current Institution Among Academic Physicians.

Importance: Physician turnover interrupts care delivery and creates health care system financial burden. Objective: To describe the prevalence of burnout, professional fulfillment, and intention to leave (ITL) among physicians at academic-affiliated health care systems and identify institutional and individual factors associated with ITL. Design, Setting, and Participants: This cross-sectional study administered a survey to 37 511 attending-level medical specialists at 15 academic medical institutions participating in the Healthcare Professional Well-Being Academic Consortium. Data were collected from October 2019 to July 2021. Statistical analysis was performed from May 2022 to March 2023. Exposures: Hypothesized institutional and individual determinants of occupational well-being. Main Outcomes and Measures: The main outcome was ITL, defined as having at least a moderate intention (a score of 2 on a 0-4 scale) to leave one's institution within the next 2 years. Additional outcomes included burnout and professional fulfillment, defined using published Professional Fulfillment Index cut points. Results: Of 18 719 academic physician survey respondents (8381 [44.8%] male; 2388 [12.8%] Asian, 10 599 [56.6%] White, 1039 [5.6%] other race, 4693 [25.1%] unknown race; 294 [1.6%] Hispanic or Latina/Latino/Latinx), 6903 of 18 217 (37.9%) met criteria for burnout and 7301 of 18 571 (39.3%) for professional fulfillment; 5177 of 15 890 (32.6%) reported moderate or greater ITL. Burnout, professional fulfillment, and ITL varied across specialties. After adjusting for demographics, each 1-point increase (range 0-10) in burnout was directly associated with ITL (odds ratio [OR], 1.52 [95% CI, 1.49-1.55])c, and each 1-point increase in professional fulfillment was inversely associated with ITL (OR, 0.64 [95% CI, 0.63-0.65]). After adjusting for demographics, burnout, and professional fulfillment, each 1-point increase (range 0-10) in supportive leadership behaviors (OR, 0.83 [95% CI, 0.82-0.84]), peer support (OR, 0.93 [95% CI, 0.91-0.95]), personal-organizational values alignment (OR, 0.81 [95% CI, 0.80-0.82]), perceived gratitude (OR, 0.95 [95% CI, 0.92-0.97]), COVID-19 organizational support (OR, 0.88 [95% CI, 0.85-0.91]), and electronic health record helpfulness (OR, 0.95 [95% CI, 0.93-0.97]) were inversely associated with ITL, whereas each 1-point increase (range 0-10) in depression (OR, 1.08 [95% CI, 1.05-1.10]) and negative impact of work on personal relationships (OR, 1.09 [1.07-1.11]) were directly associated with ITL. Conclusions and Relevance: In this cross-sectional study of academic physicians, 32.6% indicated moderate or higher ITL within 2 years. Burnout, lack of professional fulfillment, and other well-being factors were associated with ITL, suggesting the need for a comprehensive approach to reduce physician turnover.

Cardiac computed tomographic imaging to evaluate myocardial scarring/fibrosis in patients with hypertrophic cardiomyopathy: a comparison with cardiac magnetic resonance imaging.

Contrast enhanced magnetic resonance imaging (CeMRI) reliably identifies myocardial fibrosis in patients with hypertrophic cardiomyopathy (HCM). However, many patients have contraindications to ceMRI. Previous studies have shown that contrast enhanced multi-detector computed tomography (ceMDCT) can visualize focal scars following myocardial infarction in experimental animals and patients. The purpose of this manuscript is to assess the ability of ceMDCT to detect focal myocardial scars in patients with HCM. Twelve HCM patients underwent ceMRI and ceMDCT. Fibrotic areas of myocardium were defined as focal or diffuse areas of fibrosis. The mean signal intensity in ceMRI and attenuation values in ceMDCT of the fibrotic regions, normal myocardium and left ventricle blood pool contrast were measured using qualitative and quantitative analysis. Focal scar mass was calculated using both techniques. Focal scars were detected in 9 patients and diffuse fibrosis was visualized in all patients by ceMRI. Differences between normalized SI of normal myocardium and focal scars, normal and diffuse areas of fibrosis, and diffuse fibrosis and focal scars were significant for both ceMRI and ceMDCT (p < 0.05). Diffuse fibrosis was poorly visualized by ceMDCT but was detectable using quantitative measurements. CeMDCT has potential to detect focal myocardial scars in patients with HCM who have contraindications to ceMRI study. However, ceMDCT does not enable adequate visualization of diffuse myocardial fibrosis, and thus is less well suited than ceMRI for assessment of total burden of fibrosis. This limitation may be overcome using quantitative methodology.

Normalization of ejection fraction and resolution of symptoms in chronic severe heart failure is possible with modern medical therapy: clinical observations in 11 patients.

This report describes the normalization of left ventricular ejection fraction and resolution of signs and symptoms of chronic and severe heart failure in both male and female patients (mean age 54 years) treated with standard medical therapy. These observations were made in 11 patients with idiopathic dilated cardiomyopathy treated in a single cardiology practice, who had evidence of myocardial "viability" (dysfunctional but noncontractile myocardium that has the potential for improvement in function) as assessed by cardiac magnetic resonance imaging, low-dose dobutamine echocardiography, or nuclear imaging. These patients were treated with standard available therapies including beta-blockers, angiotensin-converting enzyme inhibitors, digoxin, and potassium and non-potassium-sparing diuretics. The average ejection fraction at presentation was 17% +/- 9% which improved to 59% +/- 5%. All patients improved to New York Heart Association functional class I with available therapy. The majority of patients received micronutrient supplementation with coenzyme Q10, vitamin B1, and amino acids, which target the pathways of cardiac metabolism and may aid in the restoration of cardiac function. This case series demonstrates that normalization of cardiac function is possible with standard therapy and the importance of assessing myocardial viability in all patients with heart failure and reduced ejection fraction. Given the unique metabolic needs of the failing heart, the role of micronutrients in combination with standard therapy warrants further investigation.

Elevated levels of Factor XI are associated with cardiovascular disease in women.

Coronary artery disease (CAD) continues to be the most frequent cause of death among women in the United States. Although elevated levels of clotting factors have been associated with CAD, few of these studies have been performed in women. Elevated levels of Factor XI have previously been associated with venous thrombosis, but little is known about its effect on arterial thrombosis. We selected women referred for cardiac catheterization who were found to have either normal coronaries or evidence of severe CAD and compared levels of homocysteine, anticardiolipin IgG/IgM antibodies, fibrinogen, platelet count, Factor VII, Factor VIII and Factor XI. Women with severe CAD had significantly higher levels of Factor XI than those without CAD (128% vs. 82%, p<0.04). Statistical adjustment for age, diabetes, hypertension, total cholesterol (TC), current smoking, or BMI had no effect on the independent association between CAD status and Factor XI. Factor XI was higher in women with total cholesterol levels >6.18 mmol/l (>239 mg/dl) compared with normocholesteremic women and was also higher in the upper tertile of age, but even when adjusted for these, the association remained significant. This initial study suggests that Factor XI may be an important parameter in arterial as well as venous thrombosis.
