Changes in Burnout and Satisfaction With Work-Life Integration in Physicians and the General US Working Population Between 2011 and 2020

ObjectiveTo evaluate the prevalence of burnout and satisfaction with work-life integration (WLI) among physicians and US workers in 2020 relative to 2011, 2014, and 2017.MethodsBetween November 20, 2020, and March 23, 2021, we surveyed US physicians and a probability-based sample of the US working population using methods similar to our prior studies. Burnout and WLI were measured using standard tools. Information about specific work-related COVID-19 experiences was collected.ResultsThere were 7510 physicians who participated in the survey. Nonresponder analysis suggested that participants were representative of US physicians. Mean emotional exhaustion and depersonalization scores were lower in 2020 than in 2017, 2014, and 2011 (all P<.001). However, emotional exhaustion and depersonalization scores did not improve in specialties most heavily affected by COVID-19. Overall, 38.2% of physicians reported 1 or more symptoms of burnout in 2020 compared with 43.9% in 2017, 54.4% in 2014, and 45.5% in 2011 (all P<.001). Providing care without adequate personal protective equipment (odds ratio [OR], 1.53; 95% CI, 1.35 to 1.72) and having suffered disruptive economic consequences due to COVID-19 (OR, 1.49; 95% CI, 1.32 to 1.69) were independently associated with risk of burnout. On multivariable analysis, physicians were at increased risk for burnout (OR, 1.41; 95% CI, 1.25 to 1.58) and were less likely to be satisfied with WLI (OR, 0.71; 95% CI, 0.64 to 0.79) than other working US adults.ConclusionBurnout and satisfaction with WLI among US physicians improved between 2017 and 2020. The impact of the COVID-19 pandemic on physicians varies on the basis of professional characteristics and experiences. Physicians remain at increased risk for burnout relative to workers in other fields.     

Colleagues Meeting to Promote and Sustain Satisfaction (COMPASS) Groups for Physician Well-Being: A Randomized Clinical Trial

ObjectiveTo evaluate physician small groups to promote physician well-being in a scenario with provided discussion topics but without trained facilitators, and for which protected time was not provided but meal expenses were compensated.Participants and MethodsWe conducted a randomized controlled trial of 125 practicing physicians in the Department of Medicine, Mayo Clinic, Rochester, Minnesota, between October 2013 and October 2014 with subsequent assessment of organizational program implementation. Twelve biweekly self-facilitated discussion groups involving reflection, shared experience, and small-group learning took place over 6 months. Main outcome measures included meaning in work, burnout, symptoms of depression, quality of life, social support, and job satisfaction assessed using validated metrics.ResultsAt 6 months after completion of the intervention (12 months from baseline), the rate of overall burnout had decreased by 12.7% (31/62 to 19/51) in the intervention arm versus a 1.9% increase (25/61 to 24/56) in the control arm (P<.001). The rate of depressive symptoms had decreased by 12.8% (29/62 to 17/50) in the intervention arm versus a 1.1% increase (20/61 to 19/56) in the control arm (P<.001). The proportion of physicians endorsing at least moderate self-reported likelihood of leaving their current practice in the subsequent 2 years had decreased by 1.9% (17/62 to 13/51) in the intervention arm and increased by 6.1% (14/61 to 16/55) in the control arm (P<.001). No statistically significant differences were seen in mean changes in burnout scale scores, meaning, or social support, although numeric differences generally favored the intervention.ConclusionSelf-facilitated physician small-group meetings improved burnout, depressive symptoms, and job satisfaction. This intervention represents a low-cost strategy to promote important dimensions of physician well-being.Trial Registrationclinicaltrials.gov Identifier: NCT04466423     

Suicidal Ideation and Attitudes Regarding Help Seeking in US Physicians Relative to the US Working Population

ObjectiveTo evaluate the prevalence of suicidal ideation (SI) and attitudes regarding help seeking among US physicians relative to the general US working population.Participants and MethodsA secondary analysis of a cross-sectional survey of US physicians and a probability-based sample of the US working population was conducted between October 12, 2017, and March 15, 2018. Among 30,456 invited physicians, 5197 (17.1%) completed the primary survey. Suicidal ideation in the last year, attitudes regarding help seeking, symptoms of depression, and burnout were assessed by standardized questions.ResultsAmong the 4833 physicians who responded regarding SI, 316 (6.5%) reported having suicidal thoughts in the last 12 months. Most physicians (3527 [72.9%]) reported that they would seek professional help if they had a serious emotional problem. Physicians with SI were less likely to report that they would seek help (203/316 [64.2%]) than physicians without SI (3318/4517 [73.5%]; P=.001). On multivariable analysis, symptoms of depression (odds ratio [OR], 4.42; 95% CI, 1.89 to 11.52), emotional exhaustion (OR, 1.07 each 1-point increase; 95% CI, 1.03 to 1.11), and self-valuation (OR, 0.84 each 1-point increase; 95% CI, 0.70 to 0.99) were associated with SI. Among individuals aged 29 to 65 years, physicians were more likely than workers in other fields to report SI (7.1% vs 4.3%; P<.001), a finding that persisted on multivariable analysis.ConclusionIn this national study conducted before the COVID-19 pandemic, 1 in 15 US physicians had thoughts of taking their own life in the last year, which exceeded the prevalence of SI among US workers in other fields.     

Examining Disparities and Excess Cardiovascular Mortality Before and During the COVID-19 Pandemic

ObjectiveTo investigate the patterns and demographic features of cardiovascular disease (CVD) death and subtypes myocardial infarction (MI), stroke, and heart failure in the pre–COVID-19 era (2018-2019) vs during the COVID-19 pandemic (2020-2021) in the United States.MethodsIn this cross-sectional study, we used the US Multiple Cause of Death files for 2018 to 2021 to examine the trend of excess cause-specific deaths using International Classification of Diseases, Tenth Revision codes for CVD (I00 to I99), MI (I21 and I22), stroke (I60 to I69), and heart failure (I42 and I50). Our primary outcome was excess mortality from CVD and its 3 subtypes (MI, stroke, and heart failure) between prepandemic (2018-2019) and pandemic (2020-2021) years. We performed a subgroup analysis on race and month-to-month and year-to-year variation using χ² analysis to test statistical significance.ResultsOverall, 3,598,352 CVD deaths were analyzed during the study period. There was a 6.7% excess CVD mortality, 2.5% MI mortality, and 8.5% stroke mortality during the COVID-19 pandemic (2020-2021) compared with the prepandemic era (2018-2019). Black individuals had higher excess CVD mortality (13.8%) than White individuals (5.1%; P<.001). This remained consistent across subtypes of CVD, including MI (9.6% vs 1.0%; P<.001), stroke (14.5% vs 6.9%; P<.001), and heart failure (5.1% vs ?1.2%; P<.001).ConclusionThere has been a significant rise in CVD and subtype-specific mortality during the COVID-19 pandemic that has been persistent despite 2 years since the onset of the pandemic. Excess CVD mortality has disproportionately affected Black compared with White individuals. Further studies targeting and eliminating health care disparities are necessary.     

A Longitudinal Study Exploring Learning Environment Culture and Subsequent Risk of Burnout Among Resident Physicians Overall and by Gender

ObjectiveTo explore the relationship between learning environment culture and the subsequent risk of developing burnout in a national sample of residents overall and by gender.MethodsFrom April 7 to August 2, 2016, and May 26 to August 5, 2017, we surveyed residents in their second (R2) and third (R3) postgraduate year. The survey included a negative interpersonal experiences scale (score range 1 to 7 points, higher being worse) assessing psychological safety and bias, inclusion, respect, and justice; an unfair treatment scale (score range 1 to 5 points, higher being worse), and two items from the Maslach Burnout Inventory. Individual responses to the R2 and R3 surveys were linked.ResultsThe R2 survey was completed by 3588 of 4696 (76.4%) residents; 3058 of 3726 (82.1%) residents completed the R3 survey; and 2888 residents completed both surveys. Women reported more negative interpersonal experiences (mean [SD], 3.00 [0.83] vs 2.90 [0.85], P<.001) and unfair treatment (66.5% vs. 58.7%, P<.001) than men at R2. On multivariable analysis, women at R3 were more likely than their male counterparts to have burnout (odds ratio, 1.23; 95% CI, 1.02 to 1.48; P=.03). Both men and women who reported more negative interpersonal experiences at R2 were more likely to have burnout at R3 (odds ratio, 1.32; 95% CI, 1.14 to 1.52; P<.001). The factors contributing to burnout did not vary in effect magnitude by gender.ConclusionThese findings indicate women residents are more likely to have burnout relative to men in the third year of residency. Negative culture predicted subsequent burnout 1 year later among both men and women. Differences in burnout were at least partly due to differing levels of exposure to negative interactions for men versus women rather than a negative interaction having a differential impact on the well-being of men versus women.     

Host Factors and Outcomes in Hospitalizations for Pneumocystis Jirovecii Pneumonia in the United States

ObjectiveTo assess host factors in pneumocystis jirovecii pneumonia (PCP)–related hospitalizations and compare outcomes between HIV and non-HIV patients.MethodsUsing the National Inpatient Sample database, we identified 3384 hospitalizations with PCP (International Classification of Diseases, Ninth Revision, Clinical Modification code: 136.3) as the primary discharge diagnosis from 2005 to 2014. We evaluated hospitalizations for the following host factors: HIV, malignancies, organ transplantation, rheumatologic diseases, and vasculitides. We compared the prevalence of individual host factors among PCP hospitalizations over time, and compared intervention rates and outcomes between HIV and non-HIV patients with PCP.ResultsAmong all hospitalizations for PCP, malignancy was the most prevalent host factor (46.0%, n=1559), followed by HIV (17.8%, n=604); 60.7% (n=946) of malignancies were hematologic. The prevalence of HIV among hospitalizations for PCP decreased from 25.1% in 2005 to 9.2% in 2014 (P<.001), whereas the prevalence of non-HIV immunocompromising conditions increased. Compared with HIV patients, PCP patients without HIV had higher rates of bronchoscopy (52.3% vs 26.7%, P<.001) and endotracheal intubation (17.0% vs 7.9%, P<.001), prolonged hospitalizations (11.5 vs 8.7 days, P<.001), higher hospitalization costs (86.8 vs 48.2×10³ USD, P<.001) and increased in-hospital mortality (16.0% vs 5.0%, P<.001). After adjusting for age, sex, and smoking status, there was no difference in mortality between non-HIV and HIV patients with PCP (adjusted odds ratio, 1.4; 95% CI, 0.9 to 2.3).ConclusionThe epidemiology of PCP has shifted with an increase in the prevalence of non-HIV patients who have higher intubation rates and prolonged hospitalizations compared with matched HIV patients.     

Effect of the Renin-Angiotensin System Inhibitors on Inflammatory Markers: A Systematic Review and Meta-analysis of Randomized Controlled Trials

ObjectiveTo synthesize more conclusive evidence on the anti-inflammatory effects of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs).MethodsPubMed, Scopus, and Embase were searched from inception until March 1, 2021. We included randomized controlled trials (RCTs) that assessed the effect of ACEIs or ARBs, compared with placebo, on any of the following markers: C-reactive protein (CRP), interleukin 6 (IL-6), or tumor necrosis factor α (TNF-α). Mean changes in the levels of these markers were pooled as a weighted mean difference (WMD) with a 95% CI.ResultsThirty-two RCTs (n=3489 patients) were included in the final analysis. Overall pooled analysis suggested that ACEIs significantly reduced plasma levels of CRP (WMD, ?0.54 [95% CI, ?0.88 to ?0.21]; P=.002; I²=96%), IL-6 (WMD, ?0.84 [95% CI, ?1.03 to ?0.64]; P<.001; I²=0%), and TNF-α (WMD, ?12.75 [95% CI, ?17.20 to ?8.29]; P<.001; I²=99%). Moreover, ARBs showed a significant reduction only in IL-6 (WMD, ?1.34 [95% CI, ?2.65 to ?0.04]; P=.04; I²=85%) and did not significantly affect CRP (P=.15) or TNF-α (P=.97) levels. The lowering effect of ACEIs on CRP levels remained significant with enalapril (P=.006) and perindopril (P=.01) as well as with a treatment duration of less than 24 weeks (WMD, -0.67 [95% CI, ?1.07 to -0.27]; P=.001; I²=94%) and in patients with coronary artery disease (WMD, ?0.75 [95% CI, ?1.17 to ?0.33]; P<.001; I²=96%).ConclusionBased on this meta-analysis, ACEIs showed a beneficial lowering effect on CRP, IL-6, and TNF-α, whereas ARBs were effective as a class in reduction of IL-6 only.     

Implementation of a Comprehensive Patient Blood Management Program for Hospitalized Patients at a Large United States Medical Center

ObjectiveTo assess changes in inpatient transfusion utilization and patient outcomes with implementation of a comprehensive patient blood management (PBM) program at a large US medical center.Patients and MethodsThis is an observational study of graduated PBM implementation for hospitalized adults (age ≥18 years) from January 1, 2010, through December 31, 2017, at two integrated hospital campuses at a major academic US medical center. Allogeneic transfusion utilization and clinical outcomes were assessed over time through segmented regression with multivariable adjustment comparing observed outcomes against projected outcomes in the absence of PBM activities.ResultsIn total, 400,998 admissions were included. Total allogeneic transfusions per 1000 admissions decreased from 607 to 405 over the study time frame, corresponding to an absolute risk reduction for transfusion of 6.0% (95% confidence interval [CI]: 3.6%, 8.3%; P<.001) and a 22% (95% CI: 6%, 37%; P=.006) decrease in the rate of transfusions over projected. The risk of transfusion decreased for all blood components except cryoprecipitate. Transfusion reductions were experienced for all major surgery types except liver transplantation, which remained stable over time. Hospital length of stay (multiplicative increase in geometric mean 0.85 [95% CI: 0.81, 0.89]; P<.001) and incident in-hospital adverse events (absolute risk reduction: 1.5% [95% CI: 0.1%, 3.0%]; P=.04) were lower than projected at the end of the study time frame.ConclusionPatient blood management implementation for hospitalized patients in a large academic center was associated with substantial reductions in transfusion utilization and improved clinical outcomes. Broad-scale implementation of PBM in US hospitals is feasible without signal for patient harm.     

Imposter Phenomenon in US Physicians Relative to the US Working Population

ObjectiveTo determine the prevalence of imposter phenomenon (IP) experiences among physicians and evaluate their relationship to personal and professional characteristics, professional fulfillment, burnout, and suicidal ideation.Participants and MethodsBetween November 20, 2020, and February 16, 2021, we surveyed US physicians and a probability-based sample of the US working population. Imposter phenomenon was measured using a 4-item version of the Clance Imposter Phenomenon Scale. Burnout and professional fulfillment were measured using standardized instruments.ResultsAmong the 3237 physician responders invited to complete the subsurvey including the IP scale, 3116 completed the IP questions. Between 4% (133) and 10% (308) of the 3116 physicians endorsed each of the 4 IP items as a “very true” characterization of their experience. Relative to those with a low IP score, the odds ratio for burnout among those with moderate, frequent, and intense IP was 1.28 (95% CI, 1.04 to 1.58), 1.79 (95% CI, 1.38 to 2.32), and 2.13 (95% CI, 1.43 to 3.19), respectively. A similar association between IP and suicidal ideation was observed. On multivariable analysis, physicians endorsed greater intensity of IP than workers in other fields in response to the item, “I am disappointed at times in my present accomplishments and think I should have accomplished more.”ConclusionImposter phenomenon experiences are common among US physicians, and physicians have more frequent experiences of disappointment in accomplishments than workers in other fields. Imposter phenomenon experiences are associated with increased burnout and suicidal ideation and lower professional fulfillment. Systematic efforts to address the professional norms and perfectionistic attitudes that contribute to this phenomenon are necessary.     

Increased Utilization of Virtual Visits and Electronic Approaches in Clinical Research During the COVID-19 Pandemic and Thereafter

ObjectivesTo assess the impact of the COVID-19 pandemic on clinical research and the use of electronic approaches to mitigate this impact.MethodsWe compared the utilization of electronic consenting, remote visits, and remote monitoring by study monitors in all research studies conducted at Mayo Clinic sites (Arizona, Florida, and Minnesota) before and during the COVID-19 pandemic (ie, between May 1, 2019 and December 31, 2020). Participants are consented through a participant-tracking system linked to the electronic health record.ResultsBetween May 2019, and December 2020, there were 130,800 new consents across every modality (electronic and paper) to participate in a non-trial (107,176 [82%]) or a clinical trial (23,624 [18%]). New consents declined from 5741 in February 2020 to 913 in April 2020 but increased to 11,864 in November 2020. The mean (standard deviation [SD]) proportion of electronic consent increased from 22 (2%) before to 45 (20%) during the pandemic (P=.001). Mean (SD) remote electronic consenting increased from 0.3 (0.5%) to 29 (21%) (P<.001). The mean (SD) number of patients with virtual visits increased from 3.5 (2.4%) to 172 (135%) (P=.003) per month between pre-COVID (July 2019 to February 2020) and post-COVID (March to December 2020) periods. Virtual visits used telemedicine (68%) or video (32%). Requests for remote monitor access to complete visits increased from 44 (17%) per month between May 2019 and February 2020 to 111 (74%) per month between March and December 2020 (P=.10).ConclusionAfter a sharp early decline, the enrollment of new participants and ongoing study visits recovered during the COVID-19 pandemic. This recovery was accompanied by the increased use of electronic tools.     

Women Are Less Likely to Survive AMI Presenting With Out-of-Hospital Cardiac Arrest: A Nationwide Study

ObjectiveTo assess the impact of patient’s sex on outcomes and management of acute myocardial infarction (AMI) patients presenting with out-of-hospital cardiac arrest (OHCA).Patients and MethodsWe conducted a population-based retrospective cohort study in AMI patients admitted with OHCA between 2010 and 2017 from the Myocardial Ischaemia National Audit Project (MINAP) registry. We used multivariable logistic regression models to evaluate the role of sex as a predictor of clinical outcomes and treatment strategy.ResultsOf 16,278 patients, women constituted almost one-quarter of the population (n=3710 [22.7%]). Women were older (median age 69 [IQR, 57-79] years vs 63 [IQR, 54-72] years, P<.001), experienced longer call-to-hospital-arrival time (median, 1.2 hours vs 1.1 hours; P=.008), were less likely to present with shockable rhythm (86.8% vs 91.5%, P<.001), and less likely to receive dual antiplatelet therapy (73.8% vs 78.6%, P<.001), beta blockers (64.7% vs 72.3%, P<.001), angiotensin-converting enzyme inhibitors (49.0% vs 55.3%, P<.001), coronary angiography (73.7% vs 83.3%, P<.001), and percutaneous coronary intervention (37.5% vs. 40.7%, p 0.004). After adjusting for patient characteristics and management, women had significantly higher odds of in-hospital death compared with men (odds ratio [OR], 1.3; 95% CI, 1.1 to 1.5) and lower odds of receiving coronary angiography (OR, 0.67; 95% CI, 0.59 to 0.75) and coronary artery bypass graft (OR, 0.28; 95% CI, 0.19 to 0.40).ConclusionWomen were less likely to survive following OHCA secondary to AMI. Hospital protocols that minimize physician bias and improve women-physician communication are needed to close this gap.     

Portopulmonary Hypertension in Nontransplanted Patients: Results of the Largest US Single-Institution Registry

ObjectiveTo explore clinical characteristics, risk profiles, and outcomes of patients with portopulmonary hypertension (PoPH) who have contraindications to liver transplant (LT).MethodsFrom the largest US single-institution registry of patients with PoPH, we analyzed 160 patients who did not receive LT between 1988 to 2019. Pulmonary arterial hypertension (PAH)–pertinent characteristics, hemodynamic features, treatments, and risk stratification were compared at baseline, first follow-up visit, and censor/death time.ResultsMedian survival for the entire cohort was 27.5 months from the diagnosis of PoPH. Overall survival was 89%, 77%, 51%, and 38% at 6 months, 1 year, 3 years, and 5 years, respectively. Survival was significantly affected by the severity of liver disease (P<.001). Most patients received PAH-specific therapies (136 [85%]), predominantly monotherapy (123 [77%)]. With treatment, significant improvements were noted in World Health Organization functional class (P=.04), 6-minute walk distance (P<.001), right ventricular function (P<.001), pulmonary vascular resistance (P<.001), and Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management (REVEAL) Lite 2 score (P=.02) univariately. Per European Society of Cardiology risk stratification, no patient met full criteria for low risk at baseline or at follow-up. In a multivariate Cox risk model, 6-minute walk distance, right atrial pressure, pulmonary capillary wedge pressure, bilirubin level, and Model for End-Stage Liver Disease–sodium score of 15 or higher were associated with increased risk of death.ConclusionPatients with PoPH who did not undergo LT had a poor prognosis. This persisted despite use of PAH-specific therapies and significant improvements in hemodynamics, echocardiography parameters of right ventricle function, 6-minute walk distance, and World Health Organization functional class.     

Hypertensive Diseases of Pregnancy Increase Risk of Readmission With Heart Failure: A National Readmissions Database Study

ObjectiveTo study the association between hypertensive diseases of pregnancy and immediate postpartum development of heart failure in a large national database.Patients and MethodsUsing the 2013 to 2014 National Readmissions Database, which covered admissions from January 1 through September 30 in years 2013 and 2014, we examined 90-day readmission rates in parturients with a diagnosis of hypertensive disease of pregnancy who were discharged after delivery. The primary outcome was the association between the presence of hypertensive disease of pregnancy and readmission with heart failure within 90 days of delivery discharge. Secondary outcomes included readmission mortality, time between delivery discharge and readmission, length of stay, and costs of readmission.ResultsWomen with hypertensive disease of pregnancy were more likely to be readmitted with heart failure (1809 of 25,908 readmissions (7.0%) vs 2622 of 89,660 readmissions (2.9%); P<.001). This difference persisted after adjustment for potential cofounders (6.3% vs 3.1%; odds ratio, 2.15; 95% CI, 1.92-2.40; P<.001). Women with a diagnosis of heart failure at readmission were readmitted sooner (11 days vs 23 days; P<.001) and had a longer length of stay (4 days vs 3 days; P<.001) and higher costs of readmission ($10,361 vs $6977; P<.001) than did women without a diagnosis of heart failure.ConclusionParturients with hypertensive disease of pregnancy were more likely to be readmitted with heart failure within 90 days of delivery. Most patients readmitted with heart failure were readmitted within 2 weeks of discharge after delivery. Patients readmitted with heart failure had substantial health care expenditures.     

Decline of Influenza and Respiratory Viruses With COVID-19 Public Health Measures: Alberta,Canada

ObjectiveTo determine the incidence of influenza and noninfluenza respiratory viruses (NIRVs) pre-/post-implementation of public health measures aimed to decrease coronavirus disease 2019 (COVID-19) transmission using population-based surveillance data. We hypothesized that such measures could reduce the burden of respiratory viruses (RVs) transmitting via the same routes.Patients and MethodsAn interrupted time-series analysis of RV surveillance data in Alberta, Canada, from May 2017 to July 2020 was conducted. The burden of influenza and NIRVs before and after intervention initiation at week 11 was compared. The analysis was adjusted for seasonality, overdispersion, and autocorrelation.ResultsDuring the study period, an average of 708 and 4056 weekly respiratory multiplex molecular panels were conducted pre-/post-intervention, respectively. We found significant reductions in test positivity rates in the postintervention period for influenza (-94.3%; 95% CI, -93.8 to 97.4%; P<.001) and all NIRVs (-76.5%; 95% CI, -77.3 to -75.8%; P<.001) in the crude model, and -86.2% (95% CI, -91.5 to -77.4%: P<.001) and -75% (95% CI, -79.7 to -69.3%; P<.001), respectively, in the adjusted models. Subanalyses for individual viruses showed significant decreases in respiratory syncytial virus, human metapneumovirus, enterovirus/rhinovirus, and parainfluenza. For non–severe acute respiratory coronavirus 2 human coronaviruses, the decline was not statistically significant after adjustment (-22.3%; 95% CI, -49.3 to +19%, P=.246).ConclusionThe implementation of COVID-19 public health measures likely resulted in reduced transmission of common RVs. Although drastic lockdowns are unlikely to be required given widespread COVID-19 vaccination, targeted implementation of such measures can lower RV disease burden. Studies to evaluate relative contributions of individual interventions are warranted.     

Coronary Artery Bypass Grafting in Octogenarians—Risks,Outcomes, and Trends in 1283 Consecutive Patients

ObjectiveTo describe the risks, outcomes, and trends in patients older than 80 years undergoing coronary artery bypass grafting (CABG).MethodsWe retrospectively studied 1283 consecutive patients who were older than 80 years and underwent primary isolated CABG from January 1, 1993, to October 31, 2019, in our clinic. Kaplan-Meier survival probability and quartile estimates were used to analyze patients’ survival. Logistic regression models were used for analyzing temporal trends in CABG cases and outcomes. A multivariable Cox proportional hazards regression model was developed to study risk factors for mortality.ResultsOperative mortality was overall 4% (n=51) but showed a significant decrease during the study period (P=.015). Median follow-up was 16.7 (interquartile range, 10.3-21.1) years, and Kaplan-Meier estimated survival rates at 1 year, 5 years, 10 years, and 15 years were 90.2%, 67.9%, 31.1%, and 8.2%, respectively. Median survival time was 7.6 years compared with 6.0 years for age- and sex-matched octogenarians in the general US population (P<.001). Multivariable Cox regression analysis identified older age (P<.001), recent atrial fibrillation or flutter (P<.001), diabetes mellitus (P<.001), smoking history (P=.006), cerebrovascular disease (P=.04), immunosuppressive status (P=.01), extreme levels of creatinine (P<.001), chronic lung disease (P=.02), peripheral vascular disease (P=.02), decreased ejection fraction (P=.03) and increased Society of Thoracic Surgeons predicted risk score (P=.01) as significant risk factors of mortality.ConclusionAlthough CABG in octogenarians carries a higher surgical risk, it may be associated with favorable outcomes and increase in long-term survival. Further studies are warranted to define subgroups benefiting more from surgical revascularization.     

How Feedback Is Given Matters: A Cross-Sectional Survey of Patient Satisfaction Feedback Delivery and Physician Well-being

ObjectiveTo evaluate how variation in the way patient satisfaction feedback is delivered relates to physician well-being and perceptions of its impact on patient care, job satisfaction, and clinical decision making.Participants and MethodsA cross-sectional electronic survey was sent to faculty physicians from a large academic medical center in March 29, 2019. Physicians reported their exposure to feedback (timing, performance relative to peers, or channel) and related perceptions. The Professional Fulfillment Index captured burnout and professional fulfillment. Associations between feedback characteristics and well-being or perceived impact were tested using analysis of variance or logistic regression adjusted for covariates.ResultsOf 1016 survey respondents, 569 (56.0%) reported receiving patient satisfaction feedback. Among those receiving feedback, 303 (53.2%) did not believe that this feedback improved patient care. Compared with physicians who never received feedback, those who received any type of feedback had higher professional fulfillment scores (mean, 6.6±2.1 vs 6.3±2.0; P=.03) but also reported an unfavorable impact on clinical decision making (odds ratio [OR], 2.9; 95% CI, 1.8 to 4.7; P<.001). Physicians who received feedback that included one-on-one discussions (as opposed to feedback without this channel) held more positive perceptions of the feedback’s impact on patient care (OR, 2.0; 95% CI, 1.3 to 3.0; P=.003), whereas perceptions were less positive in physicians whose feedback included comparisons to named colleagues (OR, 0.5; 95% CI, 0.3 to 0.8; P=.003).ConclusionProviding patient satisfaction feedback to physicians was associated with mixed results, and physician perceptions of the impact of feedback depended on the characteristics of feedback delivery.

Predicting 1-Year Mortality on Admission Using the Mayo Cardiac Intensive Care Unit Admission Risk Score

ObjectiveTo determine whether the Mayo Cardiac Intensive Care Unit (CICU) Admission Risk Score (M-CARS) accurately predicts 1-year mortality.MethodsWe retrospectively reviewed adult CICU patients admitted from January 1, 2007, through April 30, 2018, and calculated M-CARS using admission data. We examined the association between admission M-CARS, as continuous and categorical variables, and 1-year mortality.ResultsThis study included 12,428 unique patients with a mean age of 67.6±15.2 years (4686 [37.7%] female). A total of 2839 patients (22.8%) died within 1 year of admission, including 1149 (9.2%) hospital deaths and 1690 (15.0%) of the 11,279 hospital survivors. The 1-year survival decreased incrementally as a function of increasing M-CARS (P<.001), and all components of M-CARS were significant predictors of 1-year mortality (P<.001). The 1-year survival among hospital survivors decreased incrementally as a function of increasing M-CARS for scores below 3 (all P<.001); however, there was no further decrease in 1-year survival for hospital survivors with M-CARS of 3 or more (P=.99). The M-CARS components associated with 1-year mortality among hospital survivors included blood urea nitrogen, red blood cell distribution width, Braden skin score, and respiratory failure (all P<.001).ConclusionM-CARS predicted 1-year mortality among CICU admissions, with a plateau effect at high M-CARS of 3 or more for hospital survivors. Significant added predictors of 1-year mortality among hospital survivors included markers of frailty and chronic illness.     

Noninvasive Ventilation in the Management of Respiratory Failure Due to COVID-19 Infection: Experience From a Resource-Limited Setting

ObjectiveTo study the role of noninvasive ventilation (NIV) in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV2) related acute respiratory failure (C-ARF).Patients and MethodsPatients with C-ARF managed on NIV were categorized as NIV success or failure (death or intubation). Factors associated with failure were explored using regression analysis and expressed as odds ratio (OR) with 95% CI.ResultsBetween April 1, 2020, and September 15, 2020, a total of 286 patients with a mean ± SD age of 53.1±11.6 years and Acute Physiology and Chronic Health Evaluation II score of 11.1±5.5 were initiated on NIV. Of the 182 patients (63.6%) successfully managed on NIV alone, 118 had moderate or severe acute respiratory distress syndrome. When compared with NIV success, NIV failure was associated with lower admission PaO₂ to fraction of inspired oxygen ratio (P<.001) and higher respiratory rate (P<.001). On penalized logistic regression analysis, NIV failure was associated with higher Acute Physiology and Chronic Health Evaluation II score (OR, 1.12; 95% CI, 1.01 to 1.24), severe acute respiratory distress syndrome (OR, 3.99; 95% CI, 1.24 to 12.9), D-dimer level of 1000 ng/mL DDU (to convert to mg/L, divide by 1000) or greater (OR, 2.60; 95% CI, 1.16 to 5.87), need for inotropes or dialysis (OR, 12.7; 95% CI, 4.3 to 37.7), and nosocomial infections (OR, 13.6; 95% CI, 4.06 to 45.9). Overall mortality was 30.1% (86/286). In patients requiring intubation, time to intubation was longer in nonsurvivors than survivors (median, 5; interquartile range, 3-8 vs 3; interquartile range, 2-3 days; P<.001).ConclusionNoninvasive ventilation can be used successfully in C-ARF. Illness severity and need for non–respiratory organ support predict NIV failure.     

High-Intensity Interval Training in Cardiac Rehabilitation: Impact on Fat Mass in Patients With Myocardial Infarction

ObjectiveTo examine the effect of high-intensity interval training (HIIT) on body fat mass and distribution in patients with myocardial infarction (MI) who underwent cardiac rehabilitation (CR).Patients and MethodsWe retrospectively screened 391 consecutive patients with MI enrolled in CR between September 1, 2015, and February 28, 2018. We included 120 patients who completed 36 CR sessions and underwent pretest-posttest dual-energy x-ray absorptiometry; 90 engaged in HIIT, and 30 engaged in moderate-intensity continuous training (MICT). High-intensity interval training included 4 to 8 alternating intervals of high- (30-60 seconds at a rating of perceived exertion [RPE] of 15-17 [Borg scale range, 6-20]) and low-intensity (1-5 minutes at RPE <14), and MICT performed for 20 to 45 minutes of exercise at an RPE of 12 to 14. Body weight, fat mass, and lean mass were measured via dual-energy x-ray absorptiometry with lipid profile measured via clinical procedures.ResultsThe HIIT and MICT groups were similar in age (67 vs 67 years), sex (26.7% [24 of 90 patients in the HIIT group] vs 26.7% [8 of 30 in the MICT group), and body mass index (30.3 vs 29.5 kg/m²) at baseline. The HIIT group had greater reductions in body fat percentage (P<.001), fat mass (P<.001), abdominal fat percentage (P<.001), waist circumference (P=.01), total cholesterol (P=.002), low-density lipoprotein cholesterol (P<.001), and triglycerides (P=.006). Improvements in total body mass and body mass index were not different across groups. After matching exercise duration, exercise intensity, and energy expenditure, HIIT-induced improvements in total fat mass (P=.02), body fat percentage (P=.01), and abdominal fat percentage (P=.02) persisted.ConclusionOur data suggest that supervised HIIT results in significant reductions in total fat mass (P<.001) and abdominal fat percentage (P<.001) and improved lipid profile in patients with MI who undergo CR.     

Do Patients With COVID-19 Benefit from Rehabilitation? Functional Outcomes of the First 100 Patients in a COVID-19 Rehabilitation Unit

ObjectiveTo determine the benefits associated with brief inpatient rehabilitation for coronavirus 2019 (COVID-19) patients.DesignRetrospective chart review.SettingA newly created specialized rehabilitation unit in a tertiary care medical center.ParticipantsConsecutive sample of patients (N=100) with COVID-19 infection admitted to rehabilitation.InterventionInpatient rehabilitation for postacute care COVID-19 patients.Main Outcome MeasuresMeasurements at admission and discharge comprised a Barthel Activities of Daily Living Index (including baseline value before COVID-19 infection), time to perform 10 sit-to-stands with associated cardiorespiratory changes, and grip strength (dynamometry). Correlations between these outcomes and the time spent in the intensive care unit (ICU) were explored.ResultsUpon admission to rehabilitation, 66% of the patients were men, the age was 66±22 years, mean delay from symptom onset was 20.4±10.0 days, body mass index was 26.0±5.4 kg/m², 49% had hypertension, 29% had diabetes, and 26% had more than 50% pulmonary damage on computed tomographic scans. The mean length of rehabilitation stay was 9.8±5.6 days. From admission to discharge, the Barthel index increased from 77.3±26.7 to 88.8±24.5 (P<.001), without recovering baseline values (94.5±16.2; P<.001). There was a 37% improvement in sit-to-stand frequency (0.27±0.16 to 0.37±0.16 Hz; P<.001), a 13% decrease in post-test respiratory rate (30.7±12.6 to 26.6±6.1; P=.03), and a 15% increase in grip strength (18.1±9.2 to 20.9±8.9 kg; P<.001). At both admission and discharge, Barthel score correlated with grip strength (ρ=0.39-0.66; P<.01), which negatively correlated with time spent in the ICU (ρ=–0.57 to –0.49; P<.05).ConclusionsInpatient rehabilitation for COVID-19 patients was associated with substantial motor, respiratory, and functional improvement, especially in severe cases, although there remained mild persistent autonomy loss upon discharge. After acute stages, COVID-19, primarily a respiratory disease, might convert into a motor impairment correlated with the time spent in intensive care.
