  Background: Residency recruitment requires significant resources for both applicants and residency programs. Virtual interviews offer a way to reduce the time and costs required during the residency interview process. This prospective study investigated how virtual interviews affected scoring of anesthesiology residency applicants and whether this effect differed from in-person interview historical controls. Methods: Between November 2020 and January 2021, recruitment members at the University of Chicago scored applicants before their interview based upon written application materials alone (preinterview score). Applicants received a second score after their virtual interview (postinterview score). Recruitment members were queried regarding the most important factor affecting the preinterview score as well as the effect of certain specified applicant interview characteristics on the postinterview score. Previously published historical controls were used for comparison to in-person recruitment the year prior from the same institution. Results: values >.05). The factor identified by faculty as the most important in the preinterview score was academic achievements (64%), and faculty identified the most important interview characteristic to be personality (72%). Conclusions: Virtual interviews led to a significant change in scoring of residency applicants, and the magnitude of this change was similar compared with in-person interviews. Further studies should elaborate on the effect of virtual recruitment on residency programs and applicants.

• The Influence of the In-person Residency Interview: A Prospective Study

  BACKGROUND: This prospective study investigated whether in-person interviews affected interviewer assessments of anesthesiology residency applicants at an academic medical center, and which applicant characteristics influenced interview performance. METHODS: Eighteen faculty members involved in residency recruitment between November 2019 and January 2020 documented preinterview (after full application review) and postinterview scores of the applicants on a scale of 1 to 5. Faculty also reported the relative contributions of specific interview characteristics (personality, physical appearance, professional demeanor, discussion regarding academic/scholarly activity, and level of interest in the specialty) to their postinterview assessments. Mixed-effects models were used to assess whether interviews changed faculty assessment of applicants, and what the relative contributions of applicant characteristics were to faculty assessments. RESULTS: < 0.0001). The characteristics most affecting postinterview scores were positive impressions of applicants' personalities (marginal mean change in postinterview score, 0.259; 95% confidence interval, 0.221-0.297) and negative impressions of applicants' professional demeanor (marginal mean change, -0.257; 95% confidence interval, -0.350 to -0.164). CONCLUSIONS: In-person interviews significantly affected residency applicants' scores. Personality and professional demeanor influenced scores more than did other characteristics examined. Further studies are needed to clarify the relevance of in-person interviews to the assessment of residency applicants.

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

  Obstetric Anesthesia Digest · 2020-02-25

  article1st authorCorresponding

  ( Mayo Clin Proc . 2019;94(5):811–819) Heart disease is responsible for a quarter of all deaths in women in the United States and a leading cause of maternal morbidity and mortality. The risk of cardiovascular disease-related mortality is higher in women who have had pregnancies complicated by hypertensive diseases of pregnancy (HDP). HDPs affect up to 8.2% of US deliveries. Previous studies have shown a long-term increase in postpartum heart failure in women diagnosed with HDP. There is a lack of data from large epidemiological studies on the prevalence of readmission in the immediate postpartum period for new-onset heart failure or postpartum cardiomyopathy (PPCM). This study hypothesized that rates of readmission for newly diagnosed heart failure or PPCM in the immediate postpartum period would be higher in women with HDP.

  STUDY OBJECTIVE: To identify risk factors for pediatric postoperative respiratory failure and develop a predictive model. DESIGN: This retrospective case-control study utilized the US National Inpatient Sample (NIS) from 2012 to 2014. Significant predictors were selected, and the predicted probability of pediatric postoperative respiratory failure was calculated. Sensitivity, specificity, and accuracy were then calculated, and receiver-operator curves were drawn. SETTING: National Inpatient Sample data sets from years 2012, 2013, and 2014 were used. PATIENTS: Patients aged 17 and younger in the 2012, 2013, and 2014 NIS data sets. INTERVENTIONS: Candidate predictors included demographic variables, type of surgical procedure, a modified pediatric comorbidity score, presence of substance abuse diagnosis, and presence/absence of kyphoscoliosis. MEASUREMENTS: The primary outcome measure was the pediatric quality indicator (PDI 09), which is defined by the Agency for Healthcare Research Quality, and identifies pediatric patients with postoperative respiratory failure. MAIN RESULTS: statistic of 0.82. CONCLUSIONS: Risk factors associated with postoperative respiratory failure in pediatric patients undergoing noncardiac surgery include type of surgery (abdominal and spine) and higher pediatric comorbidity scores. A prediction model based on the identified factors had good predictive ability.

• Be Active and Be Well? A Cross-sectional Survey of US Anesthesia Residents

  Journal of Education in Perioperative Medicine · 2020-06-01 · 1 citations

  articleOpen access

  BACKGROUND: Wellness among resident physicians is important to their well-being and ability to provide clinical care. The relationship between physical activity and wellness among anesthesia residents has not yet been evaluated. We surveyed anesthesia residents to evaluate their levels of physical activity and self-perceived wellness scores. We hypothesized that residents with high self-reported physical activity levels would be more likely to have higher wellness scores. METHODS: Three hundred and twenty-three anesthesia residents were invited to participate in this cross-sectional survey study. The survey included questions regarding demographics (age, gender, clinical anesthesia year, work hours), physical activity (based off the US Department of Health and Human Services [USDHHS] guidelines), and wellness (using the Satisfaction With Life Scale). The relationship between wellness and physical activity levels was evaluated. RESULTS: value .03). CONCLUSIONS: Anesthesia resident physicians with high physical activity levels had higher self-perceived wellness scores.

• Intensivist staffing and outcome in the ICU

  Current Opinion in Anaesthesiology · 2019-01-30 · 10 citations

  review1st author

  PURPOSE OF REVIEW: Many hospitals, particularly large academic centers, have begun to provide 24-h in-house intensive care attending coverage. Proposed advantages for this model include improved patient care, greater provider, nursing and patient satisfaction, better communication, and greater cost-effectiveness. This review will evaluate current evidence with respect to 24/7 coverage, including patient outcomes, cost-effectiveness, and impact on training/education. RECENT FINDINGS: Evidence surrounding 24-h intensivist staffing has been mixed. Although a subset of studies suggest a possible benefit to 24-h intensivist coverage, recent prospective studies have shown no difference in major patient outcomes, including mortality and ICU length of stay between patients in ICUs with and those without 24-h intensivist coverage. SUMMARY: Although some studies cite increased caregiver and patient satisfaction, outcome studies find no consistent effect on patient-centered outcomes such as mortality or length of stay. Downsides to in-house nighttime attending staffing include physician burnout, adverse effects on physician health, decreased trainee autonomy, and effects on trainee specialty choices because of undesirable lifestyle considerations. Tele-ICU and other novel approaches may allow for attending supervision without physical presence.
