Physician Specialties Involved in Thyroid Cancer Diagnosis and Treatment: Implications for Improving Health Care Disparities.

CONTEXT: Little is known about provider specialties involved in thyroid cancer diagnosis and management. OBJECTIVE: Characterize providers involved in diagnosing and treating thyroid cancer. DESIGN/SETTING/PARTICIPANTS: We surveyed patients with differentiated thyroid cancer from the Georgia and Los Angeles County Surveillance, Epidemiology and End Results registries (N = 2632, 63% response rate). Patients identified their primary care physicians (PCPs), who were also surveyed (N = 162, 56% response rate). MAIN OUTCOME MEASURES: (1) Patient-reported provider involvement (endocrinologist, surgeon, PCP) at diagnosis and treatment; (2) PCP-reported involvement (more vs less) and comfort (more vs less) with discussing diagnosis and treatment. RESULTS: Among thyroid cancer patients, 40.6% reported being informed of their diagnosis by their surgeon, 37.9% by their endocrinologist, and 13.5% by their PCP. Patients reported discussing their treatment with their surgeon (71.7%), endocrinologist (69.6%), and PCP (33.3%). Physician specialty involvement in diagnosis and treatment varied by patient race/ethnicity and age. For example, Hispanic patients (vs non-Hispanic White) were more likely to report their PCP informed them of their diagnosis (odds ratio [OR]: 1.68; 95% CI, 1.24-2.27). Patients ≥65 years (vs <45 years) were more likely to discuss treatment with their PCP (OR: 1.59; 95% CI, 1.22-2.08). Although 74% of PCPs reported discussing their patients' diagnosis and 62% their treatment, only 66% and 48%, respectively, were comfortable doing so. CONCLUSIONS: PCPs were involved in thyroid cancer diagnosis and treatment, and their involvement was greater among older patients and patients of minority race/ethnicity. This suggests an opportunity to leverage PCP involvement in thyroid cancer management to improve health and quality of care outcomes for vulnerable patients.

One year of the pandemic - how European endocrinologists responded to the crisis: a statement from the European Society of Endocrinology.

Changes that COVID-19 induced in endocrine daily practice as well as the role of endocrine and metabolic comorbidities in COVID-19 outcomes were among the striking features of this last year. The aim of this statement is to illustrate the major characteristics of the response of European endocrinologists to the pandemic including the disclosure of the endocrine phenotype of COVID-19 with diabetes, obesity and hypovitaminosis D playing a key role in this clinical setting with its huge implication for the prevention and management of the disease. The role of the European Society of Endocrinology (ESE) as a reference point of the endocrine community during the pandemic will also be highlighted, including the refocusing of its educational and advocacy activities.

Endocrinologist Burnout: We Need to Tackle It and Bring Joy to Work.

CONTEXT: Physician burnout is a national problem that has gained increasing attention among the medical community. Many organizations like the American Medical Association, American College of Physicians, and the National Academy of Medicine are taking action. EVIDENCE ACQUISITION: Endocrinologists and other members of the endocrine community are not immune to burnout. Approximately 47% of endocrinologists report feeling burnt out or have experienced symptoms of burnout, and this number is rising. EVIDENCE SYNTHESIS: The consequences of burnout include personal factors such as stress, depression, and risk of suicide as well as organizational impacts like decreased quality of care, increased clinical errors, reduced empathy for patients, decreased patient satisfaction, and higher turnover rates, with some physicians leaving practice altogether. Burnout has substantial economic impacts at an organizational level, and high costs are associated with replacing, recruiting, and retraining endocrinologists. Endocrinologists identified feeling a lack of respect from administration, excessive bureaucratic tasks, increased computerization, emphasis on profit that has contributed to loss of control over schedules, and insufficient compensation as top contributors to burnout. One strategy to address burnout is to focus on the promotion of joy in work. Joy in work is guided by 4 key themes: meaning, camaraderie, choice, and equity. Each of these themes can be implemented through cocreating solutions. We discuss how each theme can be addressed among endocrine practices. CONCLUSION: Ultimately, initiatives need to be implemented across the endocrinology community to cultivate joy and reduce burnout.

Improved Glycemic Control Outcomes Regardless of Mental Health Disorders in a Pharmacist-Endocrinologist Diabetes Intense Medical Management (DIMM) "Tune Up" Clinic.

Background: Previous studies show patients with type 2 diabetes (T2D) and a mental health (MH) disorder exhibit poorer glycemic control compared with those without. Objective: Compare mean change in glycosylated hemoglobin (A1C) after 6 months in the Diabetes Intense Medical Management (DIMM) "Tune Up" Clinic in patients with and without MH disorders. Methods: Retrospective cohort study in T2D patients, with A1C at baseline and 6 months, divided into subgroups of those with ≥1 MH diagnoses and without MH. Primary outcome was mean change in A1C from baseline to 6 months. Secondary outcomes were mean change in other metabolic parameters and proportion achieving A1C and related goals. Results: Of 155 patients meeting inclusion criteria, 66 (42.6%) had at least 1 MH disorder (MH group) and 89 (57.4%) did not (non-MH group). Mean A1C, fasting blood glucose (FBG), and triglycerides (TG) change (improvement) did not differ significantly between MH and non-MH groups at 6 months (eg, A1C reduction: -2.1% [SD = 2.0] vs -2.3% [SD = 2.1]; P = 0.61, respectively). Percentage at A1C goal did not differ significantly between groups, though a higher percentage of the non-MH group achieved FBG and TG goals than the MH group. Conclusion and Relevance: In 6 months, both groups in the DIMM clinic achieved a statistically significant mean A1C reduction (over 2%) with no statistical or clinical difference in the magnitude of change between groups. Patients with T2D benefitted from the DIMM model and personalized visits with a pharmacist regardless of having a MH disorder.

Physician experts in diabetes are natural team leaders for managing diabetic patients with foot complications. A position statement from the Italian diabetic foot study group.

Diabetic foot syndrome (DFS) is a complex disease. The best outcomes are reported with the multi-disciplinary team (MDT) approach, where each member works collaboratively according to his/her expertise. However, which health provider should act as the team leader (TL) has not been determined. The TL should be familiar with the management of diabetes, related complications and comorbidities. He/she should be able to diagnose and manage foot infections, including prompt surgical treatment of local lesions, such as abscesses or phlegmons, in an emergent way in the first meeting with the patient. According to the Organization for Economic Co-operation and Development (OECD) reports, Italy is one of countries with a low amputation rate in diabetic patients. Many factors might have contributed to this result, including 1)the special attention directed to diabetes by the public health system, which has defined diabetes as a "protected disease", and accordingly, offers diabetic patients, at no charge, the best specialist care, including specific devices, and 2)the presence of a network of diabetic foot (DF) clinics managed by diabetologists with medical and surgical expertise. The health care providers all share a "patient centred model" of care, for which they use their internal medicine background and skills in podiatric surgery to manage acute or chronic needs in a timely manner. Therefore, according to Italian experiences, which are fully reported in this document, we believe that only a skilled diabetologist/endocrinologist should act as a TL. Courses and university master's degree programmes focused on DF should guarantee specific training for physicians to become a TL.

Diabetes Care Editors' Expert Forum 2018: Managing Big Data for Diabetes Research and Care.

Technological progress in the past half century has greatly increased our ability to collect, store, and transmit vast quantities of information, giving rise to the term "big data." This term refers to very large data sets that can be analyzed to identify patterns, trends, and associations. In medicine-including diabetes care and research-big data come from three main sources: electronic medical records (EMRs), surveys and registries, and randomized controlled trials (RCTs). These systems have evolved in different ways, each with strengths and limitations. EMRs continuously accumulate information about patients and make it readily accessible but are limited by missing data or data that are not quality assured. Because EMRs vary in structure and management, comparisons of data between health systems may be difficult. Registries and surveys provide data that are consistently collected and representative of broad populations but are limited in scope and may be updated only intermittently. RCT databases excel in the specificity, completeness, and accuracy of their data, but rarely include a fully representative sample of the general population. Also, they are costly to build and seldom maintained after a trial's end. To consider these issues, and the challenges and opportunities they present, the editors of Diabetes Care convened a group of experts in management of diabetes-related data on 21 June 2018, in conjunction with the American Diabetes Association's 78th Scientific Sessions in Orlando, FL. This article summarizes the discussion and conclusions of that forum, offering a vision of benefits that might be realized from prospectively designed and unified data-management systems to support the collective needs of clinical, surveillance, and research activities related to diabetes.

RECALSEEN. La atención al paciente en las unidades de Endocrinología y Nutrición del Sistema Nacional de Salud / Patient care in the Endocrinology and Nutrition Units of the National Health System. The RECALSEEN study

Objetivos: Elaborar un registro de situación de los Servicios y Unidades de Endocrinología y Nutrición (S°EyN) del Sistema Nacional de Salud (SNS) y valorar sus recursos asistenciales para desarrollar, a partir de los resultados obtenidos, propuestas de políticas de mejora en los S°EyN. Material y métodos: Estudio descriptivo transversal de los pacientes atendidos en los S°EyN en hospitales generales de agudos del SNS en 2016. Se utilizaron datos obtenidos mediante RECALSEEN 2017, una encuesta «ad hoc» diseñada específicamente para este fin y de las altas dadas por los S°EyN registradas en el CMBD del SNS (2015). Resultados: De un total de 125 hospitales generales de agudos de más de 200 camas instaladas del SNS español, se han obtenido 88 respuestas de los S°EyN, que representan el 70%. El 47% de los S°EyN que respondieron eran servicios y el 31% secciones. El promedio de endocrinólogos por S°EyN era de 7,4±4,4, siendo la tasa media de endocrinólogos por cada 100.000 habitantes de 2,3±1. Las actividades asistenciales más relevantes eran la consulta (promedio de 12,3 primeras consultas por mil habitantes y año), hospital de día (mediana de 2.000 sesiones/año) e interconsulta hospitalaria (mediana de 900 interconsultas/año). El 83% de los S°EyN incorporaban una Unidad de Nutrición Clínica. La dotación de dietistas, técnicos en nutrición y bromatólogos en las Unidades de Nutrición Clínica era baja. En relación con la gestión de la calidad se detectó un amplio margen de mejora; solamente un 35% de los S°EyN tenían responsable de calidad y el 38% había implantado una gestión por procesos para aquellos más frecuentemente atendidos por la unidad. Existen notables diferencias en estructura, recursos y actividad de los S°EyN entre Comunidades Autónomas. Conclusiones: La encuesta RECALSEEN 2017 es útil para el análisis de los S°EyN. La notable variabilidad hallada en los indicadores de estructura, actividad y gestión probablemente indica relevantes diferencias y, por tanto, un amplio margen de mejora

Objectives: To elaborate a diagnosis of the situation regarding the assistance in the Services and Units of Endocrinology and Nutrition (S°EyN) of the National Health System of Spain (SNHS) and to develop, based on the results obtained, proposals for improvement policies in the S°EyN. Material and methods: Cross-sectional descriptive study of the patients treated in the S°EyN departments of acute general hospitals of the SNHS in 2016. Data were obtained through RECALSEEN 2017, an "ad hoc" survey designed specifically for this purpose, and the Minimum Basic Data Set of discharges given by the S°EN of the SNHS (2015). Results: 88 responses of S°EyN have been obtained forma total of 125 acute general hospitals of more than 200 beds installed in the SNHS (70% answers). 47% of the S°EyN respondents were services and 31% sections. The average of endocrinologists by S°EyN was 7.4±4.4, and the average rate of endocrinologists per 100,000 inhabitants was 2.3±1. The most relevant care activities were the consultation (average of 12.3 first consultations per thousand inhabitants and year), day hospital (median of 2,000 sessions/year) and in-hospital consultations (median of 900 in-hospital consultations/year). 83% of S°EyNhad a Clinical Nutrition Unit. The number of dietitians, nutrition technicians and nutritionists in the Clinical Nutrition Unit was low. In relation to quality management, a large margin for improvement was detected; only 35% of S°EyN had a responsible of quality and 38% had implemented process management for those most frequent processes in the unit. There were notable differences in structure, resources and activity of S°EyN between Autonomous Communities. Conclusions: RECALSEEN 2017 survey is a useful tool for the analysis of S°EyN. The remarkable variability found in the structure, activity and management indicators probably indicates significant differences and, therefore, a wide margin for improvement

CONSENSUS STATEMENT BY THE AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY ON THE QUALITY OF DXA SCANS AND REPORTS.

OBJECTIVE: High-quality dual-energy X-ray absorptiometry (DXA) scans are necessary for accurate diagnosis of osteoporosis and monitoring of therapy; however, DXA scan reports may contain errors that cause confusion about diagnosis and treatment. This American Association of Clinical Endocrinologists/American College of Endocrinology consensus statement was generated to draw attention to many common technical problems affecting DXA report conclusions and provide guidance on how to address them to ensure that patients receive appropriate osteoporosis care. METHODS: The DXA Writing Committee developed a consensus based on discussion and evaluation of available literature related to osteoporosis and osteodensitometry. RESULTS: Technical errors may include errors in scan acquisition and/or analysis, leading to incorrect diagnosis and reporting of change over time. Although the International Society for Clinical Densitometry advocates training for technologists and medical interpreters to help eliminate these problems, many lack skill in this technology. Suspicion that reports are wrong arises when clinical history is not compatible with scan interpretation (e.g., dramatic increase/decrease in a short period of time; declines in previously stable bone density after years of treatment), when different scanners are used, or when inconsistent anatomic sites are used for monitoring the response to therapy. Understanding the concept of least significant change will minimize erroneous conclusions about changes in bone density. CONCLUSION: Clinicians must develop the skills to differentiate technical problems, which confound reports, from real biological changes. We recommend that clinicians review actual scan images and data, instead of relying solely on the impression of the report, to pinpoint errors and accurately interpret DXA scan images.

AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY GUIDELINES FOR MANAGEMENT OF DYSLIPIDEMIA AND PREVENTION OF CARDIOVASCULAR DISEASE - EXECUTIVE SUMMARYComplete Appendix to Guidelines available at http://journals.aace.com.

OBJECTIVE: The development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). METHODS: Each Recommendation is based on a diligent review of the clinical evidence with transparent incorporation of subjective factors. RESULTS: The Executive Summary of this document contains 87 Recommendations of which 45 are Grade A (51.7%), 18 are Grade B (20.7%), 15 are Grade C (17.2%), and 9 (10.3%) are Grade D. These detailed, evidence-based recommendations allow for nuance-based clinical decision making that addresses multiple aspects of real-world medical care. The evidence base presented in the subsequent Appendix provides relevant supporting information for Executive Summary Recommendations. This update contains 695 citations of which 202 (29.1 %) are evidence level (EL) 1 (strong), 137 (19.7%) are EL 2 (intermediate), 119 (17.1%) are EL 3 (weak), and 237 (34.1%) are EL 4 (no clinical evidence). CONCLUSION: This CPG is a practical tool that endocrinologists, other healthcare professionals, regulatory bodies and health-related organizations can use to reduce the risks and consequences of dyslipidemia. It provides guidance on screening, risk assessment, and treatment recommendations for a range of patients with various lipid disorders. These recommendations emphasize the importance of treating low-density lipoprotein cholesterol (LDL-C) in some individuals to lower goals than previously recommended and support the measurement of coronary artery calcium scores and inflammatory markers to help stratify risk. Special consideration is given to patients with diabetes, familial hypercholesterolemia, women, and pediatric patients with dyslipidemia. Both clinical and cost-effectiveness data are provided to support treatment decisions.

2017 AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS/ENDOCRINE SOCIETY UPDATE ON TRANSGENDER MEDICINE: CASE DISCUSSIONS.

OBJECTIVE: Increased numbers of transgender and gender-nonconforming people are presenting to physicians in the United States and abroad due to increased public recognition and acceptance and increased access to healthcare facilities. However, there are still gaps in medical knowledge among endocrinologists and other health care professionals. The purpose of these cases is to present several common clinical vignettes of transgender people presenting in an office setting that illustrate some of the key recommendations of the Endocrine Society's revised Endocrine Treatment of Gender Dysphoria/Gender Incongruent Persons guidelines, cosponsored by the American Association of Clinical Endocrinologists. METHODS: Cases were developed based on these recently revised guidelines for gender-dysphoric and gender-nonconforming persons. RESULTS: Six cases are presented that illustrate the diagnosis, treatment, and long-term management of trans-gender children and adults based on the revised guidelines for the endocrine care of gender-dysphoric and gender-nonconforming persons. Several key teaching points are presented from the presentation of these cases. CONCLUSION: Endocrinologists should be familiar with the revised guidelines for gender-dysphoric and gender-nonconforming persons. Important aspects of care are the diagnosis of gender dysphoria, the timing of treatment with gender-affirming hormones, and the long-term monitoring for potential adverse outcomes. Long-term health outcome studies are needed to further help guide care in this unique population.

AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY POSITION STATEMENT ON TESTING FOR AUTONOMIC AND SOMATIC NERVE DYSFUNCTION.

This document represents the official position of the American Association of Clinical Endocrinologists and the American College of Endocrinology. Where there were no randomized controlled trials or specific U.S. FDA labeling for issues in clinical practice, the participating clinical experts utilized their judgment and experience.

Position statements are meant to provide guidance, but they are not to be considered prescriptive for any individual patient and cannot replace the judgment of a clinician.

eCONSULTS TO ENDOCRINOLOGISTS IMPROVE ACCESS AND CHANGE PRIMARY CARE PROVIDER BEHAVIOR.

OBJECTIVE: To describe the impact of an eConsult service on access to endocrinologists along with its influence on changing primary care provider (PCP) course of action and referral behaviors. METHODS: Established in 2011, the Champlain BASE (Building Access to Specialist Care via eConsult) service allows PCPs to access specialist care in lieu of traditional face-to-face referrals. We conducted a cross-sectional study of eConsult cases submitted to endocrinologists by PCPs between April 15, 2011 and January 31, 2015. Usage data and PCP responses to a mandatory closeout survey were analyzed to determine eConsult response times, PCP practice behavior, referral outcomes, and provider satisfaction. Each eConsult was coded according to clinical topic and question type based on established taxonomies. RESULTS: A total of 180 PCPs submitted 464 eConsults to endocrinology during the study period. Specialist median response time was 7 hours, with 90% of responses occurring within 3 days. PCPs received a new or additional course of action in 62% of submitted cases. An unnecessary face-to-face referral was avoided in 44% of all eConsults and in 67% of cases where the PCP initially contemplated requesting a referral. Over 95% of cases were rated at least 4 out of 5 in value for PCPs and their patients. CONCLUSION: The use of eConsult improves access to endocrinologists by providing timely, highly rated practice-changing clinical advice while reducing the need for patients to attend face-to-face office visits.

AMERICAN ASSOCIATION OF CLINICAL ENDOCRINOLOGISTS AND AMERICAN COLLEGE OF ENDOCRINOLOGY DISEASE STATE CLINICAL REVIEW: UPDATE ON GROWTH HORMONE STIMULATION TESTING AND PROPOSED REVISED CUT-POINT FOR THE GLUCAGON STIMULATION TEST IN THE DIAGNOSIS OF ADULT GROWTH HORMONE DEFICIENCY.

OBJECTIVE: The clinical features of adult GH deficiency (GHD) are nonspecific, and GH stimulation testing is often required to confirm the diagnosis. However, diagnosing adult GHD can be challenging due to the episodic and pulsatile GH secretion, concurrently modified by age, gender, and body mass index (BMI). METHODS: PubMed searches were conducted to identify published data since 2009 on GH stimulation tests used to diagnose adult GHD. Relevant articles in English language were identified and considered for inclusion in the present document. RESULTS: Testing for confirmation of adult GHD should only be considered if there is a high pretest probability, and the intent to treat if the diagnosis is confirmed. The insulin tolerance test (ITT) and glucagon stimulation test (GST) are the two main tests used in the United States. While the ITT has been accepted as the gold-standard test, its safety concerns hamper wider use. Previously, the GH-releasing hormone-arginine test, and more recently the GST, are accepted alternatives to the ITT. However, several recent studies have questioned the diagnostic accuracy of the GST when the GH cut-point of 3 µg/L is used and have suggested that a lower GH cut-point of 1 µg/L improved the sensitivity and specificity of this test in overweight/obese patients and in those with glucose intolerance. CONCLUSION: Until a potent, safe, and reliable test becomes available, the GST should remain as the alternative to the ITT in the United States. In order to reduce over-diagnosing adult GHD in overweight/obese patients with the GST, we propose utilizing a lower GH cut-point of 1 µg/L in these subjects. However, this lower GH cut-point still needs further evaluation for diagnostic accuracy in larger patient populations with varying BMIs and degrees of glucose tolerance.
