Background Internal medicine (IM) resident physicians spend a considerable amount of time managing their inbox as part of their longitudinal continuity clinic experience. There are no standardized guidelines for how programs should train, monitor, or supervise residents in this type of patient care. Objective To understand how IM residency programs educate, monitor, and supervise resident electronic health record (EHR) inbox management as part of their longitudinal continuity clinic and determine whether patient safety events have occurred due to EHR inbox-related patient care decisions made by unsupervised resident physicians. Methods In August 2021, 439 program directors at accredited US IM residency programs who were members of the Association of Program Directors in Internal Medicine (APDIM) were asked 12 questions developed by the study authors and APDIM survey committee members regarding resident EHR inbox management as part of the annual APDIM survey. Results Two hundred and sixty-seven (61%) PDs responded. The majority (224 of 267, 84%) of programs provided guidelines for expected message response times; less than half (115, 43%) monitored timeliness metrics. Only half (135; 51%) of programs required faculty supervision of inbox messages for all residents; 28% (76) did not require supervision for any residents. Twenty-one percent of PDs (56) reported awareness of a patient safety event occurring due to an unsupervised resident inbox-related patient care decision. Conclusions Substantial variability exists in how IM residency programs train, monitor, supervise, and provide coverage for resident inbox work. Program directors are aware of patient safety events resulting from unsupervised resident inbox management.

Abstract Purpose Professional identity formation (PIF) is a dynamic process by which an individual internalizes the core values and beliefs of a specific profession. Within medical education, PIF begins in medical school and continues throughout training and practice. Transitions affect PIF, with a critical transition occurring between medical training and unsupervised practice. This study aims to characterize PIF during the transition from resident to early-career faculty physician and explores the relationship between PIF and burnout during this transition. Method The authors conducted a qualitative study using constructivist grounded theory. They conducted semistructured interviews with early-career faculty physicians (defined as practicing for ≤ 5 years) from the Department of Medicine, Mayo Clinic. Deidentified interview transcripts were processed through open and axial coding. The authors organized themes and identified relationships between themes that were refined through discussion and constant comparison with newly collected data. During data analysis, the authors identified self-determination theory, with the concepts of autonomy, competence, and relatedness, as a framework to support the organization and analysis of the data. Results Eleven early-career faculty physicians participated in the interviews. Their PIF was characterized by the dual desires to fit in and stand out. Striving for these desires was characterized by imposter syndrome, driving physicians to question their decision making and overall competence. Participants associated imposter syndrome and academic pressures with burnout. Autonomy support by the institution to pursue opportunities important for career development helped mitigate burnout and support PIF. Conclusions Early-career faculty physicians face identity challenges when transitioning from training to unsupervised practice, including striving to fit in and stand out. They link this tension to imposter syndrome, which they associated with burnout. Institutional awareness and support, including addressing structural and cultural contributors to imposter syndrome, are paramount as new faculty explore their identities and navigate new challenges.

Abstract Purpose To examine associations of social support and social isolation with burnout, program satisfaction, and organization satisfaction among a large population of U.S. residents and fellows and to identify correlates of social support and social isolation. Method All residents and fellows enrolled in graduate medical education programs at Mayo Clinic sites were surveyed in February 2019. Survey items measured social support (emotional and tangible), social isolation, burnout, program satisfaction, and organization satisfaction. Factors of potential relevance to social support were collected (via the survey, institutional administrative records, and interviews with program coordinators and/or program directors) and categorized as individual, interpersonal, program, or work-related factors (duty hours, call burden, elective time, vacation days used before survey administration, required away rotations, etc.). Multivariable regression analyses were conducted to examine relationships between variables. Results Of 1,146 residents surveyed, 762 (66%) from 58 programs responded. In adjusted models, higher emotional and tangible support were associated with lower odds of burnout and higher odds of program and organization satisfaction, while higher social isolation scores were associated with higher odds of burnout and lower odds of program satisfaction and organization satisfaction. Independent predictors of social support and/or social isolation included age, gender, relationship status, parental status, postgraduate year, site, ratings of the program leadership team, ratings of faculty relationships and faculty professional behaviors, satisfaction with autonomy, and vacation days used before survey administration. Conclusions This study demonstrates that social support and social isolation are strongly related to burnout and satisfaction among residents and fellows. Personal and professional relationships, satisfaction with autonomy, and vacation days are independently associated with social support and/or social isolation, whereas most program and work-related factors are not. Additional studies are needed to determine if social support interventions targeting these factors can improve well-being and enhance satisfaction with training.

Sympathetic neural control has a central role in the regulation of blood pressure. In humans, muscle sympathetic nerve activity (MSNA) is strongly controlled by the arterial baroreflex. Our goal was to evaluate a calculation of blood pressure "error signal" for MSNA burst occurrence and test if there was a gender difference in the relationship between this signal and resting blood pressure. Baseline MSNA was measured in healthy young men (n=49) and women (n=23). T50 (the DBP at which there is a 50% likelihood of an MSNA burst) was calculated. Mean DBP was subtracted from the T50 as an approximate "error signal" for burst activation. We found a positive relationship between this "error signal" and MSNA (bursts/100 heartbeats; BI) in both young men (slope=0.19, r 2 =0.67, p<0.001) and women (slope=0.32, r 2 =0.78, p<0.001). Thus, if DBP was lower than T50, there was an increased likelihood of MSNA bursts and vice versa. Women had a greater average "error signal" (i.e., mean T50 ‐ DBP = ‐5 ± 1 in women and ‐2 ± 0.4 in men), a 59 % steeper slope of the error signal:MSNA relationship, and lower mean BI (31 ± 2 vs 42 ± 4, p<0.05), suggesting that mechanisms exist in women to counteract the larger "driving force" for generation of a MSNA burst. These apparent gender differences in control of MSNA may contribute to differences in prevalence of cardiovascular diseases such as hypertension.

Physical activity (PA) is inversely related with body fat, insulin resistance (IR), and leptin. However, these associations are not clear in patients after gastric bypass surgery (GBS). We hypothesized an inverse relation between PA, BMI, IR, and leptin; and a positive relation between leptin, BMI, and IR in a group of 9 patients after GBS, 8 obese (Ob), and 7 non‐obese (N‐Ob) controls (age=39.0±5.7, 27.7±6.9, 28.0±10.2 yr, respectively). Subjects wore an accelerometer from 6‐7 days, and underwent measurements of height, weight, DEXA, blood glucose, insulin and leptin. IR was estimated using HOMA. Between group differences in PA, BMI, IR, and leptin were determined with ANOVA; and the relation between these variables was determined with simple linear regressions. Between group differences were observed for BMI (Ob=38.7±1.6, GBS=30.4±1.5, N‐Ob=23.8±1.7 kg/m2), IR (Ob=3.0±0.5, GBS=1.1±0.5, N‐Ob=0.7±0.5), and leptin (Ob=55.9, GBS=28.7±4.5, N‐Ob=5.1±5.6 ng/ml). PA was not different between groups. Inverse associations were observed between PA and BMI (r= ‐ 0.55), and leptin (r= ‐ 0.56); and positive associations were observed between leptin and BMI (r= 0.92), and IR (r= 0.63). PA appears to be associated with the control of obesity and IR possibly via reductions in leptin, a mechanism that requires further study. Funded by NIH CTSA UL1‐RR24150, NIH CTSA KL2‐ RR024151

The physiological changes that occur after gastric bypass surgery (GBS) are not well understood but changes in activation of the sympathetic nervous system may be involved. We hypothesized that GBS would be associated with greater sympathetically mediated resting energy expenditure as measured by a greater decrease in REE after beta‐blockade (beta‐REE). Subjects who had undergone GBS (average reduction in BMI of 31.6% from peak, N=7) along with lean (BMI<25 kg/m 2 , N=5) and obese (BMI=35–45 kg/m 2 , N=4) subjects underwent measurements of REE before and after IV propranolol (0.25 mg/kg bolus followed by an infusion of 0.004 mg/kg/min). The decrease in REE (mean±SD) after beta‐blockade tended to be greater in lean (102±58 kcal) compared with obese (−22±100 kcal) and GBS (26±55 kcal) subjects (P=0.06). The decrease in REE after beta‐blockade negatively correlated with the % body fat (r=0.54, P<0.05) and VO 2max (r=0.67, P=0.01) of the subjects, but not with resting catecholamine or leptin levels. We did not find that subjects who had undergone GBS had a significant difference in the amount of their REE that is dependent on sympathetic stimulation. Beta‐REE appears to be related to fitness and also to fatness and the fact that GBS subjects had high body fat even after significant weight loss may explain our results.

The vascular effects of prostacyclin and contribution of endothelial derived nitric oxide (NO) to prostacyclin mediated dilation are unknown in aging. A pilot study was performed in healthy older subjects (n=6, 61–73 years old) and younger controls (n=6, 19–45 years old) that were matched for BMI. Subjects underwent brachial artery catheterization and received escalating doses of epoprostenol (PGI 2 2.5, 5, 10 ng/100ml forearm tissue/min) followed by sodium nitroprusside (SNP 0.25, 0.5, 1 mcg/100ml forearm tissue/min) after PGI 2 washout. SNP and PGI 2 were repeated after NO synthase inhibition with N G ‐Monomethyl‐L arginine acetate (L‐NMMA 1mg/min after 50mg load). Using venous occlusion plethysmography, forearm vascular conductance (FVC) was calculated using mean arterial pressure (MAP), as FVC= (FBF/MAP X 100). Percent change in FVC from baseline after PGI 2 was lower in the aging individuals (47, 160, 227 % change FVC) compared to younger controls (85, 218, 327 %change FVC) (p=0.039), L‐NMMA reduced baseline FVC similarly, and the dilator response to PGI 2 was no longer significant between groups. SNP effects were not significant between groups and unaffected by L‐NMMA. This data suggests a reduced effect to prostacyclin in the aging individual may be due to a reduction in the contribution of endothelial derived NO. Support provided by HL‐46493 and UL1‐RR24150.

Problem Distress, depression, and burnout are common during medical training. Stigma surrounding seeking help for mental illness during medical training may involve fear of negative peer perceptions, academic jeopardy, and adverse future career consequences. Faculty disclosure of personal mental health illness may reduce stigma surrounding mental health disorders and reassure and encourage trainees to seek help when needed. Approach The authors aimed to assess the impact of faculty disclosure of mental health issues on stigma toward help-seeking during training, self-reflection about mental health, and resident physician awareness of mental health resources. Three self-selected faculty members shared their personal experiences with depression and mental health during a confidential noon conference intended for internal medicine residents at Mayo Clinic Rochester as part of their core curriculum in December 2016. Institutional and community mental health resources were provided. After the conference, attendees completed an anonymous survey assessing self-reported knowledge, attitudes, and behaviors surrounding mental health during medical training. Outcomes One hundred percent of residents (39/39) agreed that they enjoyed the conference. Thirty-five of 39 (89.7%) respondents agreed that their knowledge of available mental health resources increased and 33/39 (84.6%) agreed they were more likely to pursue mental health resources after attending the conference. Thirty-eight of 39 (97.4%) residents agreed that faculty sharing their personal struggles destigmatizes mental health issues during training, and the same percentage reported engaging in postconference self-reflection regarding their own mental health and well-being. Next Steps Resident conference sessions during which faculty self-disclose personal mental health experiences may help decrease the stigma of mental health issues during medical training and increase the likelihood residents will seek assistance when needed. The authors encourage further study of longer-term outcomes and actual help-seeking behaviors across learner levels and training environments.
