Surgery Clerkship Directors' Perceptions of the COVID-19 Pandemic's Impact on Medical Student Education

BACKGROUND

This study assessed the national impact of the coronavirus disease 2019 (COVID-19) pandemic on the education of medical students assigned to surgery clerkship rotations, as reported by surgery clerkship directors (CDs).

STUDY DESIGN

In the spring of 2020 and 2021, the authors surveyed 164 CDs from 144 Liaison Committee on Medical Education-accredited US medical schools about their views of the pandemic's impact on the surgery clerkship curriculum, students' experiences, outcomes, and institutional responses.

RESULTS

Overall survey response rates, calculated as number of respondents/number of surveyed, were 44.5% (73 of 164) and 50.6% (83 of 164) for the spring 2020 and 2021 surveys, respectively. Nearly all CDs (more than 95%) pivoted to virtual platforms and solutions. Most returned to some form of in-person learning by winter 2020, and prepandemic status by spring 2021 (46%, 38 of 83). Students' progression to the next year was delayed by 12% (9 of 73), and preparation was negatively impacted by 45% (37 of 83). Despite these data, CDs perceived students' interest in surgical careers was not significantly affected (89% vs 77.0%, p = 0.09). During the 1-year study, the proportion of CDs reporting a severe negative impact on the curriculum dropped significantly (p < 0.0001) for most parameters assessed except summative evaluations (40.3% vs 45.7%, p = 0.53). CDs (n = 83) also noted the pandemic's positive impact with respect to virtual patient encounters (21.7%), didactics (16.9%), student test performance (16.9%), continuous personal learning (14.5%), engagement in the clerkship (9.6%), and student interest in surgery as a career (7.2%).

CONCLUSIONS

During the pandemic, the severe negative impact on student educational programs lessened, and novel virtual curricular solutions emerged. Student interest in surgery as a career was sustained. Measures of student competency and effectiveness of new curriculum, including telehealth, remain areas for future investigation.

Changing Surgical Culture Through Surgical Education: Introduction to the PACTS Trial

The Provider Awareness and Cultural dexterity Toolkit for Surgeons (PACTS) curriculum was developed to improve surgical resident cultural dexterity, with the goal of promoting health equity by developing cognitive skills to adapt to individual patients' needs to ensure personal, patient-centered surgical care through structured educational interventions for surgical residents. Funded by the National Institute of Health (NIH)'s National Institute on Minority Health and Health Disparities, PACTS addresses surgical disparities in patient care by incorporating varied educational interventions, with investigation of both traditional and nontraditional educational outcomes such as patient-reported and clinical outcomes, across multiple hospitals and regions. The unique attributes of this multicenter, multiphased research trial will not only impact future surgical education research, but hopefully improve how surgeons learn nontechnical skills that modernize surgical culture and surgical care. The present perspective piece serves as an introduction to this multifaceted surgical education trial, highlighting the rationale for the study and critical curricular components such as key stakeholders from multiple institutions, multimodal learning and feedback, and diverse educational outcomes.

Development and Validation of a Novel Literature-Based Method to Identify Disparity-Sensitive Surgical Quality Metrics

BACKGROUND

Disparity in surgical care impedes the delivery of uniformly high-quality care. Metrics that quantify disparity in care can help identify areas for needed intervention. A literature-based Disparity-Sensitive Score (DSS) system for surgical care was adapted by the Metrics for Equitable Access and Care in Surgery (MEASUR) group. The alignment between the MEASUR DSS and Delphi ratings of an expert advisory panel (EAP) regarding the disparity sensitivity of surgical quality metrics was assessed.

STUDY DESIGN

Using DSS criteria MEASUR co-investigators scored 534 surgical metrics which were subsequently rated by the EAP. All scores were converted to a 9-point scale. Agreement between the new measurement technique (ie DSS) and an established subjective technique (ie importance and validity ratings) were assessed using the Bland-Altman method, adjusting for the linear relationship between the paired difference and the paired average. The limit of agreement (LOA) was set at 1.96 SD (95%).

RESULTS

The percentage of DSS scores inside the LOA was 96.8% (LOA, 0.02 points) for the importance rating and 94.6% (LOA, 1.5 points) for the validity rating. In comparison, 94.4% of the 2 subjective EAP ratings were inside the LOA (0.7 points).

CONCLUSIONS

Applying the MEASUR DSS criteria using available literature allowed for identification of disparity-sensitive surgical metrics. The results suggest that this literature-based method of selecting quality metrics may be comparable to more complex consensus-based Delphi methods. In fields with robust literature, literature-based composite scores may be used to select quality metrics rather than assembling consensus panels.

Disparity-Sensitive Measures in Surgical Care: A Delphi Panel Consensus

BACKGROUND

In the US, disparities in surgical care impede the delivery of uniformly high-quality care to all patients. There is a lack of disparity-sensitive measures related to surgical care. The American College of Surgeons Metrics for Equitable Access and Care in Surgery group, through research and expert consensus, aimed to identify disparity-sensitive measures in surgical care.

STUDY DESIGN

An environmental scan, systematic literature review, and subspecialty society surveys were conducted to identify potential disparity-sensitive surgical measures. A modified Delphi process was conducted where panelists rated measures on both importance and validity. In addition, a novel literature-based disparity-sensitive scoring process was used.

RESULTS

We identified 841 potential disparity-sensitive surgical measures. From these, our Delphi and literature-based approaches yielded a consensus list of 125 candidate disparity-sensitive measures. These measures were rated as both valid and important and were supported by the existing literature.

CONCLUSION

There are profound disparities in surgical care within the US healthcare system. A multidisciplinary Delphi panel identified 125 potential disparity-sensitive surgical measures that could be used to track health disparities, evaluate the impact of focused interventions, and reduce healthcare inequity.

Lived Experiences of Surgical Residents During the COVID-19 Pandemic: A Qualitative Assessment

OBJECTIVE

As the COVID-19 pandemic dynamically changes our society, it is important to consider how the pandemic has affected the training and wellness of surgical residents. Using a qualitative study of national focus groups with general surgery residents, we aim to identify common themes surrounding their personal, clinical, and educational experiences that could be used to inform practice and policy for future pandemics and disasters.

DESIGN

Six 90-minute focus groups were conducted by a trained qualitative researcher who elicited responses on six predetermined topics. De-identified transcripts and audio recordings were later analyzed by two independent researchers who organized responses to each topic into themes.

SETTING

Focus groups were conducted virtually and anonymously.

PARTICIPANTS

General surgery residents were recruited from across the country. Demographic information of potential participants was coded, and subjects were randomly selected to ensure a diverse group of participants.

RESULTS

The impact of the COVID-19 pandemic on residents' clinical, educational, and personal experiences varied depending on the institutional response of the program and the burden of COVID-19 cases geographically. Many successes were identified: the use of telehealth and virtual didactics, an increased sense of camaraderie amongst residents, and flexibility in scheduling. Many challenges were also identified: uncertainty at work regarding personal protective equipment and scheduling, decreased case volume and educational opportunities, and emotional trauma and burnout associated with the pandemic.

CONCLUSIONS

These data gathered from our qualitative study highlight a clear, urgent need for thoughtful institutional planning and policies for the remainder of this and future pandemics. Residency programs must ensure a balanced training program for surgical residents as they attempt to master the skills of their craft while also serving as employed health care providers in a pandemic. Furthermore, a focus on wellness, in addition to clinical competency and education, is vital to resident resilience and success in a pandemic setting.

Long term outcomes in older trauma patients admitted to the ICU: A prospective study

BACKGROUND

Prior studies have shown an increase in mortality in elderly patients when compared to their younger cohort.

METHODS

Level 1 trauma patients ≥50 years old were recruited upon admission to the ICU and prospectively followed. After an initial survey, inpatient data were collected and phone surveys were completed at 3 and 6 months.

RESULTS

100 patients were included. There was an 18% inpatient mortality. At 6 months, the mortality rate was 24%; 73% of surviving patients reported good health. 6-month nonsurvivors had a higher percentage requiring preinjury assistance with ambulation.

CONCLUSIONS

Severe trauma in patients ≥50 years of age carries a significant rate of mortality however survivors have good outcomes. Need for assistance with ambulation prior to injury is associated with 6 month mortality and could be used as a screening tool for interventions.

Preferences and Predictions Regarding Palliative Care in the Trauma Intensive Care Unit

INTRODUCTION

In the older intensive care unit (ICU) trauma population, it is common to have to make decisions about end-of-life. We sought to demonstrate uncertainty of patients and providers in this area.

METHODS

Our study is a prospective observational study of trauma patients 50 years and older admitted to the ICU. Patients or surrogates completed a survey including questions regarding end-of-life. Team members were surveyed with their expectation for patient outcome and appropriateness of palliative or comfort care. Patients were followed up for 6 months. Chi-square analysis and Fisher's exact test were performed.

RESULTS

100 patients had data available for analysis. Surveys were completed by the patient for 39 while a surrogate completed the survey for 61 patients. There was a significant increase in uncertainty if a surrogate answered or if there had been no prior discussions about end-of-life. Nurse, resident, and attending predictions about hospital survival were similar with all groups predicting survival in 82%. 6-month survivors were only predicted to be alive 75% of the time. Ideas about comfort care were similar but there was more variation regarding a palliative care consult with nurses saying yes in 27% of surveys while physicians only said yes in 18%.

CONCLUSIONS

The significantly higher rates of uncertainty for both surrogates or in cases where no prior discussion had been had highlight the importance of having more conversations about end-of-life and documentation of advance directives prior to traumatic events. The difference in team member ideas about palliative care demonstrates a need for improved team communication.

Impact of the COVID-19 pandemic on surgical trainee education and well-being spring 2020-winter 2020: A path forward

Background

The time course and longitudinal impact of the COVID -19 pandemic on surgical education(SE) and learner well-being (LWB)is unknown.

Material and methods

Check-in surveys were distributed to Surgery Program Directors and Department Chairs, including general surgery and surgical specialties, in the summer and winter of 2020 and compared to a survey from spring 2020. Statistical associations for items with self-reported ACGME Stage and the survey period were assessed using categorical analysis.

Results

Stage 3 institutions were reported in spring (30%), summer (4%) [p < 0.0001] and increased in the winter (18%). Severe disruption (SD) was stage dependent (Stage 3; 45% (83/184) vs. Stages 1 and 2; 26% (206/801)[p < 0.0001]). This lessened in the winter (23%) vs. spring (32%) p = 0.02. LWB severe disruption was similar in spring 27%, summer 22%, winter 25% and was associated with Stage 3.

Conclusions

Steps taken during the pandemic reduced SD but did not improve LWB. Systemic efforts are needed to protect learners and combat isolation pervasive in a pandemic.

Reassessing career pathways of surgical leaders: An examination of surgical leaders' early accomplishments

BACKGROUND

The American College of Surgeon (ACS), American Surgical Association (ASA), Association of Women Surgeons (AWS), and Society of Black Academic Surgeons (SBAS) partnered to gain insight into whether inequities found in surgical society presidents may be present earlier.

METHODS

ACS, ASA, AWS, and SBAS presidents' CVs were assessed for demographics and scholastic achievements at the time of first faculty appointment. Regression analyses controlling for age were performed to determine relative differences across societies.

RESULTS

66 of the 68 presidents' CVs were received and assessed (97% response rate). 50% of AWS future presidents were hired as Instructors rather than Assistant professors, compared to 29.4% of SBAS, 25% of ASA and 29.4% of ACS. The future ACS, ASA, and SBAS presidents had more total publications than the AWS presidents, but similar numbers of 1st and Sr. author publications.

CONCLUSION

Gender inequities in academic surgeon hiring practices and perceived scholastic success may be present at first hire.

Impact of the COVID-19 Pandemic on Surgical Training and Learner Well-Being: Report of a Survey of General Surgery and Other Surgical Specialty Educators

BACKGROUND

The COVID-19 pandemic disrupted the delivery of surgical services. The purpose of this communication was to report the impact of the pandemic on surgical training and learner well-being and to document adaptations made by surgery departments.

STUDY DESIGN

A 37-item survey was distributed to educational leaders in general surgery and other surgical specialty training programs. It included both closed- and open-ended questions and the self-reported stages of GME during the COVID-19 pandemic, as defined by the ACGME. Statistical associations for items with stage were assessed using categorical analysis.

RESULTS

The response rate was 21% (472 of 2,196). US stage distribution (n = 447) was as follows: stage 1, 22%; stage 2, 48%; and stage 3, 30%. Impact on clinical education significantly increased by stage, with severe reductions in nonemergency operations (73% and 86% vs 98%) and emergency operations (8% and 16% vs 34%). Variable effects were reported on minimal expected case numbers across all stages. Reductions were reported in outpatient experience (83%), in-hospital experience (70%), and outside rotations (57%). Increases in ICU rotations were reported with advancing stage (7% and 13% vs 37%). Severity of impact on didactic education increased with stage (14% and 30% vs 46%). Virtual conferences were adopted by 97% across all stages. Severity of impact on learner well-being increased by stage-physical safety (6% and 9% vs 31%), physical health (0% and 7% vs 17%), and emotional health (11% and 24% vs 42%). Regardless of stage, most but not all made adaptations to support trainees' well-being.

CONCLUSIONS

The pandemic adversely impacted surgical training and the well-being of learners across all surgical specialties proportional to increasing ACGME stage. There is a need to develop education disaster plans to support technical competency and learner well-being. Careful assessment for program advancement will also be necessary. The experience during this pandemic shows that virtual learning and telemedicine will have a considerable impact on the future of surgical education.

LaSalle D. Leffall, M.D., FACS and Leadership in American Surgery

The term, Festschrift, is defined as a volume of learned articles or essays by colleagues and admirers, serving as a tribute to a scholar. The recognition of LaSalle D. Leffall, Jr., M.D., F.A.C.S. adds credence to the merits of such a tribute.

The Implications of Transfer to an Acute Care Surgical Tertiary Service

Tertiary hospitals are increasingly called on by smaller hospitals and free-standing emergency rooms (ERs) to provide surgical care for complex patients. This study assesses patients transferred to an acute care surgery service. The ER and transfer center logs, as well as billing data, were reviewed for 12 months for all cases evaluated by acute care surgery. The charts were reviewed for demographics, comorbidities, and outcomes. A total of 111 transferred patients with complete data were identified, with 59 transferred from another hospital and 52 from a free-standing ER. The hospital transfer patients were older with more comorbidities, had a longer length of stay, and were more likely discharged to skilled care. There was no difference in the percent of patients requiring a procedure; however, significantly more procedures in the hospital transfer group were done by nonsurgical specialties Better infrastructure to monitor the impact of hospital transfers is warranted in the setting of the complex patient population transferred to tertiary hospitals.

Setting a National Agenda for Surgical Disparities Research: Recommendations From the National Institutes of Health and American College of Surgeons Summit

Health care disparities (differential access, care, and outcomes owing to factors such as race/ethnicity) are widely established. Compared with other groups, African American individuals have an increased mortality risk across multiple surgical procedures. Gender, sexual orientation, age, and geographic disparities are also well documented. Further research is needed to mitigate these inequities. To do so, the American College of Surgeons and the National Institutes of Health-National Institute of Minority Health and Disparities convened a research summit to develop a national surgical disparities research agenda and funding priorities. Sixty leading researchers and clinicians gathered in May 2015 for a 2-day summit. First, literature on surgical disparities was presented within 5 themes: (1) clinician, (2) patient, (3) systemic/access, (4) clinical quality, and (5) postoperative care and rehabilitation-related factors. These themes were identified via an exhaustive preconference literature review and guided the summit and its interactive consensus-building exercises. After individual thematic presentations, attendees contributed research priorities for each theme. Suggestions were collated, refined, and prioritized during the latter half of the summit. Breakout sessions yielded 3 to 5 top research priorities by theme. Overall priorities, regardless of theme, included improving patient-clinician communication, fostering engagement and community outreach by using technology, improving care at facilities with a higher proportion of minority patients, evaluating the longer-term effect of acute intervention and rehabilitation support, and improving patient centeredness by identifying expectations for recovery. The National Institutes of Health and American College of Surgeons Summit on Surgical Disparities Research succeeded in identifying a comprehensive research agenda. Future research and funding priorities should prioritize patients' care perspectives, workforce diversification and training, and systematic evaluation of health technologies to reduce surgical disparities.

Can routine trauma bay chest x-ray be bypassed with an extended focused assessment with sonography for trauma examination?

The objective of this study was to investigate the feasibility of using ultrasound (US) in place of portable chest x-ray (CXR) for the rapid detection of a traumatic pneumothorax (PTX) requiring urgent decompression in the trauma bay. All patients who presented as a trauma alert to a single institution from August 2011 to May 2012 underwent an extended focused assessment with sonography for trauma (FAST). The thoracic cavity was examined using four-view US imaging and were interpreted by a chief resident (Postgraduate Year 4) or attending staff. US results were compared with CXR and chest computed tomography (CT) scans, when obtained. The average age was 37.8 years and 68 per cent of the patients were male. Blunt injury occurred in 87 per cent and penetrating injury in 12 per cent of activations. US was able to predict the absence of PTX on CXR with a sensitivity of 93.8 per cent, specificity of 98 per cent, and a negative predictive value of 99.9 per cent compared with CXR. The only missed PTX seen on CXR was a small, low anterior, loculated PTX that was stable for transport to CT. The use of thoracic US during the FAST can rapidly and safely detect the absence of a clinically significant PTX. US can replace routine CXR obtained in the trauma bay and allow more rapid initiation of definitive imaging studies.

Procalcitonin elevation suggests a septic source

Procalcitonin is used as a marker for sepsis but there is little known about the correlation of the procalcitonin elevation with the causative organism in sepsis. All patients aged 18 to 80 years who were admitted to the surgery service from June 2010 to May 2012 and who had a procalcitonin drawn were evaluated. Culture data were reviewed to determine the causative organism. Infections analyzed included pneumonia, urinary tract infection (UTI), bloodstream infection, and Clostridium difficile. Other parameters assessed included reason for admission, body mass index, pressor use, antibiotic duration, and disposition. Two hundred thirty-two patient records were reviewed. Patients without a known infection/source of sepsis had a mean procalcitonin of 3.95. Those with pneumonia had a procalcitonin of 20.59 (P = 0.03). Those with a UTI had a mean procalcitonin of 66.84 (P = 0.0005). Patients with a bloodstream infection had a mean procalcitonin of 33.30 (P = 0.003). Those with C. difficile had a procalcitonin of 47.20 (P = 0.004). When broken down by causative organisms, those with Gram-positive sepsis had a procalcitonin of 23.10 (P = 0.02) compared with those with Gram-negative sepsis at 32.75 (P = 0.02). Those with fungal infections had a procalcitonin of 42.90 (P = 0.001). These data suggest that procalcitonin elevation can help guide treatment by indicating likely causative organism and infection type. These data may provide a good marker for initiation of antifungal therapy.

Basic ultrasound training can replace chest radiography for safe tube thoracostomy removal

An ultrasound (US) examination can be easily and rapidly performed at the bedside to aide in clinical decisions. Previously we demonstrated that US was safe and as effective as a chest x-ray (CXR) for removal of tube thoracostomy (TT) when performed by experienced sonographers. This study sought to examine if US was as safe and accurate for the evaluation of pneumothorax (PTX) associated with TT removal after basic US training. Patients included had TT managed by the surgical team between October 2012 and May 2013. Bedside US was performed by a variety of members of the trauma team before and after removal. All residents received, at minimum, a 1-hour formal training class in the use of ultrasound. Data were collected from the electronic medical records. We evaluated 61 TTs in 61 patients during the study period. Exclusion of 12 tubes occurred secondary to having incomplete imaging, charting, or death before having TT removed. Of the 49 remaining TT, all were managed with US imaging. Average age of the patients was 40 years and 30 (61%) were male. TT was placed for PTX in 37 (76%), hemothorax in seven (14%), hemopneumothorax in four (8%), or a pleural effusion in one (2%). Two post pull PTXs were correctly identified by residents using US. This was confirmed on CXR with appropriate changes made. US was able to successfully predict the safe TT removal and patient discharge at all residency levels after receiving a basic US training program.

Withdrawal of care in a trauma intensive care unit: the impact on mortality rate

Withdrawal of care has increased in recent years as the population older than 65 years of age has increased. We sought to investigate the impact of this decision on our mortality rate. We retrospectively reviewed a prospectively collected database to determine the percentage of cases in which care was actively withdrawn. Neurologic injury as the cause for withdrawal, age of the patient, number of days to death, number of cases thought to be treatment failures, and the reason for failure were analyzed. Between January 2008 and December 2012, there were 536 trauma service deaths; 158 (29.5%) had care withdrawn. These patients were 67 (± 18.5) years old and neurologic injury was responsible in 63 per cent (± 5.29%). Fifty-two per cent of the patients died by Day 3; 65 per cent by Day 5; and 74 per cent Day 7. A total of 22.7 per cent (± 7.9%) could be considered a treatment failure. Accounting for cases in which care was withdrawn for futility would decrease the overall mortality rate by approximately 23 per cent. Trauma center mortality calculation does not account for care withdrawn. Treating an active, aging population, with advance directives, requires methodologies that account for such decision-making when determining mortality rates.

Outer membrane vesicles alter inflammation and coagulation mediators

INTRODUCTION

Outer membrane vesicles (OMVs) were previously shown to be capable of initiating the inflammatory response seen in the transition of an infection to sepsis. However, another tenet of sepsis is the development of a hypercoagulable state and the role of OMVs in the development of this hypercoagulability has not been evaluated. The objective of this study was to evaluate the ability of OMVs to elicit endothelial mediators of coagulation and inflammation and induce platelet activation.

METHODS

Human umbilical vein endothelial cells (HUVECs) were incubated with OMVs and were analyzed for the expression of tissue factor (TF), thrombomodulin, and the adhesion molecules P-selectin and E-selectin. Supernatants of OMV-treated HUVECs were mixed with whole blood and assessed for prothrombotic monocyte-platelet aggregates (MPA).

RESULTS

OMVs induce significantly increased expression of TF, E-selectin, and P-selectin, whereas, the expression of thrombomodulin by HUVECs is significantly decreased (P < 0.05). The lipopolysaccharide inhibitor clearly inhibited the expression of E-selectin following incubation with OMVs, although its impact on TF and thrombomodulin expression was nominal. Incubation of whole blood with supernatant from HUVECs exposed to OVMs resulted in increased MPAs.

CONCLUSIONS

This study demonstrates that, at the cellular level, OMVs from pathogenic bacteria play a complex role in endothelial activation. Although OMV-bound lipopolysaccharide modulates inflammatory proteins, including E-selectin, it has a negligible effect on the tested coagulation mediators. Additionally, endothelial activation by OMVs facilitates platelet activation as indicated by increased MPAs. By influencing the inflammatory and coagulation cascades, OMVs may contribute to the hypercoagulable response seen in sepsis.

Characteristics of highly ranked applicants to general surgery residency programs

IMPORTANCE

With duty hour debates, specialization, and sex distribution changes in the applicant pool, the relative competitiveness for general surgery residency (GSR) is undefined.

OBJECTIVE

To determine the modern attributes of top-ranked applicants to GSR. DESIGN Validation cohort, survey.

SETTING

National sample of university and community-based GSR programs.

PARTICIPANTS

Data were abstracted from Electronic Residency Application Service files of the top 20-ranked applicants to 22 GSR programs. We ranked program competitiveness and blinded review of personal statements.

MAIN OUTCOMES AND MEASURES

Characteristics associated with applicant ranking by the GSR program (top 5 vs 6-20) and ranking by highly competitive programs were identified using t and χ2 tests and modified Poisson regression.

RESULTS

There were 333 unique applicants among the 440 Electronic Residency Application Service files. Most applicants had research experience (93.0%) and publications (76.8%), and 28.4% had Alpha Omega Alpha membership. Nearly half were women (45.2%), with wide variation by program (20.0%-75.0%) and a trend toward fewer women at programs in the South and West (38.0% and 37.5%, respectively). Men had higher United States Medical Licensing Examination Step 1 scores (238.0 vs 230.1; P < .001) but similar Step 2 scores (245.3 vs 244.5; P = .54). Using bivariate analysis, highly competitive programs were more likely to rank applicants with publications, research experience, Alpha Omega Alpha membership, higher Step 1 scores, and excellent personal statements and those who were male or Asian. However, the only significant predictors were Step 1 scores (relative risk [RR], 1.36 for every 10-U increase), publications (RR, 2.20), personal statements (RR, 1.62), and Asian race (RR, 1.70 vs white). Alpha Omega Alpha membership (RR, 1.62) and Step 1 scores (RR, 1.01) were the only variables predictive of ranking in the top 5.

CONCLUSIONS AND RELEVANCE

This national sample shows GSR is a highly competitive, sex-neutral discipline in which academic performance is the most important factor for ranking, especially in the most competitive programs. This study will inform applicants and program directors about applicants to the GSR program.

Transitioning to thoracic endovascular repair: a single institution's analysis of the management of blunt aortic injury

Over the past 15 years, there has been a rapid transformation in the way blunt aortic injuries (BAIs) are managed shifting from open thoracotomies to thoracic endovascular repairs (TEVAR). As a result of this change, we sought to describe our experience with open and endovascular repairs through a retrospective analysis of all trauma patients admitted with BAI to our Level I trauma center from 2002 to 2011. Demographic data, type of repair, complications, length of stay (LOS) data, and mortality were identified. No difference was noted in age, sex, Injury Severity Score, or Glasgow Coma Scale score between the two groups. There were also no differences in the number of acute complications or mortality. Intensive care unit (ICU) LOS was significantly shorter in the TEVAR group (20 vs 9 days, P < 0.05). Additionally, there was a trend toward shorter hospital LOS (28 vs 18 days, P = 0.07) and ventilator length of stay (12 vs 5 days, P = 0.171). In summary, endovascular repair of BAI is safe and has no increased rate of acute complications or mortality. ICU LOS is much shorter with TEVAR, and there was a trend toward shorter ventilator and hospital LOS, all of which may result in decreased cost. Still, more needs to be learned about potential long-term complications.

In-training assessments used in the United States surgical residency programmes

INTRODUCTION

Quality and safety concerns have always been the impetus for evaluating surgical competence. This paper provides a focused overview of key historical events that lead to the development and implementation of surgical training standards and competency assessments in the United States.

METHODS

Focused review of surgical literature.

RESULTS

The following events were found to correlate with the development and implementation of training standards and competency assessments: (i) The Flexner Report issued in 1910; (ii) The American Medical Association's 1928 endorsement of the 'Essentials of Approved Residencies and Fellowships'; and (iii) The formation of several major surgical organizations - American College of Surgeons (1913), American Board of Surgery (1937), Residency Review Committee for Surgery (1950) and Association of Program Directors in Surgery (1966).

DISCUSSION

The process by which competence is assessed in the US surgical training programmes is multifactorial and heavily linked to the structure and function of several national organizations in surgery and medicine.

Accuracy of magnetic resonance cholangiopancreatography for diagnosing stones in the common bile duct in patients with abnormal intraoperative cholangiograms

BACKGROUND

Magnetic resonance cholangiopancreatography (MRCP) is a noninvasive method for diagnosing choledocholithiasis. It is said to be as accurate as the gold standard endoscopic retrograde cholangiopancreatography (ERCP) for detecting common bile duct (CBD) stones. A study was needed to look at the accuracy of MRCP compared with intraoperative cholangiography (IOC) for detecting stones in the CBD. The aim of this study was to evaluate the diagnostic accuracy of MRCP in patients with choledocholithiasis diagnosed with IOC.

METHODS

This was a retrospective study looking at patients who underwent IOC. Results were compared with respective preoperative MRCP results if available.

RESULTS

Four hundred twenty patients who underwent IOC were reviewed and met criteria for the study. Seventy patients had preoperative MRCP. Accuracy of MRCP when compared with IOC was 70%.

CONCLUSIONS

MRCP has a high rate of false normal results compared with IOC and is not as accurate as more invasive techniques. There is no need for preoperative MRCP in patients with suspected choledocholithiasis caused by stones.

Ventilator-associated pneumonia: depends on your definition

Reduction of hospital-acquired infections is a patient safety goal and regularly monitored by Performance Improvement committees. There is discordance between the ventilator-associated pneumonia (VAP) rate reported by the Infection Control Committee (ICC) and that observed by our Trauma Service. To investigate this difference, a retrospective evaluation of cases of VAP diagnosed on a single service was undertaken. A prospectively collected database was queried for VAP in intensive care unit patients between January 2010 and June 2011. This was compared with the list of mechanically ventilated patients provided by the ICC. Comparison for criteria used to diagnose pneumonia, ventilator day of the diagnosis, was recorded. The ICC identified two VAPs from 136 potential patients compared with the Trauma Service identifying 36 VAPs. A difference in diagnostic criteria between the ICC and the Trauma Service focused on use of the National Nosocomial Infection Survey (NNIS) algorithm versus quantitative microbiology from bronchoalveolar lavage specimens. Thirty-five of 36 Trauma Service VAPs were not identified as VAPs by the NNIS algorithm as a result of the chest radiographs. Application of differing definitions of VAP results in markedly different VAP rates. The difference has significant implications as infection rates are increasingly reported as a quality metric.

Evaluation of preoperative risk factors for converting laparoscopic to open cholecystectomy

Performing laparoscopic cholecystectomy (LC) always carries the risk of having to convert from laparoscopic to open cholecystectomy (LOC). Being able to identify these patients preoperatively may allow better preoperative planning and lowering operative cost. All LC and LOC were performed by the Eastern Virginia Medical School Department of Surgery retrospectively identified between January 2008 and December 2009. Preoperative risk factors identified in both groups included: age, gender, body mass index greater than 30 kg/m(2), diabetes mellitus, previous upper abdominal surgery, previous abdominal surgery, presence of pericholecystic fluid, gallbladder wall thickness greater than 3 mm, preoperative diagnosis of acute cholecystitis, and pancreatitis. Reasons for conversion in the LOC group were identified from the operative note. A total of 346 LC and LOC were identified. The LOC group had 41 identified with a conversion rate of 11.9 per cent. The LOC group was compared with 100 randomly chosen LC. Risk factors that reached statistical significance for conversion included advanced age, male gender, previous upper abdominal surgery, preoperative diagnosis of acute cholecystitis, and gallbladder wall thickness greater than 3 mm (P = 0.0009). Average operative time was higher in LOC compared with open cholecystectomy (123 minutes average vs 109 minutes average). Of the reasons for conversion, the degree of inflammation was the most common (51.2%). Preoperative risk factors that were associated with need for conversion were advanced age, male gender, previous upper abdominal surgery, preoperative diagnosis of acute cholecystitis, and pericholecystitic fluid. In patients who have all of these risk factors, we recommend starting with an open cholecystectomy. This will save operative time and overall cost.

Screening human immunodeficiency virus-positive men for anal intraepithelial neoplasia

Squamous cell carcinoma of the anus is rare, but more common in men with human immunodeficiency virus (HIV). We describe our findings in 50 biopsies done on 37 HIV-positive men over 5 years. The men were referred from our HIV clinic for abnormal cytology on anal pap or anal condyloma. Thirty-seven patients were referred from the HIV clinic for abnormal cytology on anal pap or the presence of anal condyloma. Biopsies were done in the operating room using acetic acid to visually localize areas of dysplasia. If no abnormalities were seen, biopsies were taken from each quadrant of the anus. A retrospective review was done for biopsy indication, pathology, recurrence, and correlation with anal pap results. On initial biopsy, anal condyloma conferred the presence of anal intraepithelial neoplasia (AIN) in 64.7 per cent (11 of 17), abnormal paps in 83.3 per cent (10 of 12), and both in 50 per cent (3 of 6). Patients with anal condyloma had AIN in an average of 2.5 quadrants whereas those with abnormal cytology had AIN in 2.3 quadrants. Thirty-four of 50 biopsies showed abnormalities (68%), with AIN present in 32 cases, one case of carcinoma in situ, and one case of invasive carcinoma. Aldara was used nine times with improvement in four cases. In HIV-positive men, the presence of condyloma warrants surgical biopsy. Performing anal cytology on patients with anal condyloma did not increase the rate of positive results. Patients with AIN often had disease in more than two quadrants, making surgical excision problematic.

MRI as an adjunct to cervical spine clearance: a utility analysis

Cervical spine (CS) injury occurs in 1 to 3 per cent of blunt trauma patients. The goal of this study is to evaluate the use of magnetic resonance imaging (MRI) as an adjunct to CS computed tomography (CT) in the presence of persistent pain with a normal physical examination or obtundation. A retrospective chart review was performed on 389 blunt trauma patients undergoing both CS CT and MRI between 2007 and 2010. Abnormal CT findings were found in 199. The remaining 190 patients with normal CT scans underwent MRI for persistent pain (109), neurologic symptoms (57), or obtundation (24). Motor vehicle crashes predominated (50%) followed by falls (19%) and motorcycle crashes (12%). In the patients with persistent pain, CT showed no acute injury (89%) with subsequent MRI demonstrating ligamentous edema or injury not seen on CT in 12 per cent of patients. No patient required an operation for CS instability. All the obtunded patients demonstrated localizing motion of four extremities. MRI of these patients demonstrated ligamentous edema or injury not seen on CT in 20 per cent of patients. No obtunded patient had CS instability or needed operative intervention. A localizing physical examination in conjunction with normal CS CT safely precludes a CS injury requiring cervical fixation. MRI does not add substantially to this decision-making and the cervical collar can be safely removed.

Ultrasound-guided breast biopsy for surgical residents: evaluation of a phantom model

BACKGROUND

Ultrasound is increasingly used by surgeons for evaluation of breast lesions. While surgical residents have sufficient exposure to breast surgery, many lack exposure to office-based procedures, such as ultrasound-guided breast biopsy. A phantom model was created to teach surgical residents basic breast ultrasound and biopsy skills and to evaluate the resident's response when incorporated into the curriculum.

METHODS

The model was created using a pork roast and 10 variably-sized pimento olives. Twenty-four surgical residents were given a brief introduction to breast ultrasound followed by up to 5 minutes to ultrasound the model and note the embedded lesions. The number and location of lesions found and the time spent per resident were recorded. Residents were then introduced to the vacuum-assisted core biopsy system and observed performing ultrasound-guided biopsies. Pre- and postsession evaluations were completed by all residents. Scatterplot regression models were used for data analysis.

RESULTS

Most residents had previous ultrasound instruction. The intermediate level residents (postgraduate year [PGY]2 and 3) found the most lesions in the shortest time, missing on average 1.125 lesions in 3:09 minutes. Time spent did not correlate with number missed or previous ultrasound experience. Over 50% of residents sampled the center of the lesion on their first biopsy attempt, with no correlation to PGY or ultrasound experience. All residents rated this experience good to excellent, and 67% believed their ultrasound skills were improved. Ninety-five percent of residents felt the model was fairly realistic and 95% would like to have more experiences like this in the curriculum. The residents surveyed thought the curriculum would be best suited to a PGY2 experience.

CONCLUSIONS

The phantom breast is a realistic and valuable teaching model for breast ultrasound. Further evaluation regarding skill retention is needed.

Integrating cultural competency and humility training into clinical clerkships: surgery as a model

BACKGROUND

Cultural competency is gaining recognition as an essential strategy by which to address health care disparities. A closer examination of medical school curriculums was undertaken to determine how the need for cultural competency and humility (CCH) training in medical education is being addressed.

METHODS

A MEDLINE review of published literature regarding CCH training in medical education was performed. Additionally, key informant interviews with influential faculty members from prominent medical institutions were completed.

RESULTS

Many academic medical institutions recognize the need for CCH and have successfully integrated it into the first 2 years of their curriculums. However, there seems to be a uniform deficit in CCH training in the third and fourth years of their education.

CONCLUSIONS

Recognizing the need for CCH training during the third and fourth years of medical education, we explored the issues inherent to the integration of CCH training in clinical education. Using surgery as a model, we established a set of recommendations to assist clerkship directors and curriculum committees in their efforts to ensure CCH training in the last 2 years of medical education.

Cervical spinal cord injury associated with near-drowning does not increase pneumonia risk or mortality

Body surfing accidents (BSA) can cause cervical spinal cord injuries (CSCIs) that are associated with near-drowning (ND). The submersion injury from a ND can result in aspiration and predispose to pulmonary complications. We predicted a worse outcome (particularly the development of pneumonia) in patients with CSCIs associated with ND. A retrospective review was performed of patients who were treated at Eastern Virginia Medical School for a CSCI resulting from a blunt mechanism. Data collected included basic demographic data, data regarding injury and in-hospital outcomes, and discharge data, including discharge disposition. Statistics were performed using χ(2) and Student t test. In 2003 to 2008, 141 patients were treated for CSCIs with inclusion criteria. Thirty patients (21%) had an associated ND (BSA) and 111 patients (79%) did not (BLT). The cohorts were similar in mean age (BSA, 45 years; BLT, 50 years; P = 0.16) and male gender distribution (BSA, 93%; BLT, 79%; P = 0.13). The cohorts were similar in injury severity using Injury Severity Score (BSA, 22; BLT, 24; P = 0.65). The cohorts were similar in rates of developing pneumonia (BSA, 3%; BLT, 12%; P = 0.31). The rate of infection was significantly higher in the cohort without an associated near-drowning (BSA, 10%; BLT, 32%; P = 0.033). The mean intensive care unit stay (BSA, 3.5 days; BLT, 11.3 days; P = 0.057) and the rate of mortality were similar (BSA, 10%; BLT, 10% P = 0.99). Those patients with an associated ND had a shorter hospital stay (BSA, 5.7 days; BLT, 22.2 days; P = 0.007) and a better chance of being discharged home (BSA, 57%; BLT, 27%; P = 0.004). CSCIs after a BSA do better than their counterparts without an associated ND. CSCIs associated with ND appear to be isolated injuries with minimal pulmonary involvement despite submersion injuries.

The incidence of benign and malignant neoplasia presenting as acute appendicitis

Acute appendicitis remains the most common surgical emergency encountered by the general surgeon. It is most often secondary to lymphoid hyperplasia, however it can also result from obstruction of the appendiceal lumen by a mass. We sought to review our experience with neoplasia presenting as appendicitis. We retrospectively reviewed all patients admitted with the diagnosis of appendicitis to our Acute Care Surgery Service from July 1, 2007 to June 30, 2009. Patient demographics, duration of symptoms, lab findings, computed tomography findings, and pathology were all analyzed. Over the 2-year period, 141 patients underwent urgent appendectomy. Ten patients (7.1%) were diagnosed with neoplasia on final pathology, including four women and six men with a mean age of 46.9 years and mean duration of symptoms of 12.6 days. Final pathology revealed four colonic adenocarcinoma; three mucinous tumors; one carcinoid; one endometrioma; and one patient had a combination of a mucinous cystadenoma, a carcinoid tumor, and endometriosis of the appendix. Six patients had concurrent appendicitis. Colonic and appendiceal neoplasia are not unusual etiologies of appendicitis. These patients tend to present at an older age and with longer duration of symptoms.
