Role of Collaborative Academic Partnerships in Surgical Training, Education, and Provision

Robert Riviello; Doruk Ozgediz; Renee Y. Hsia; Mark Newton; John L. Tarpley

The global disparities in both surgical disease burden and access to delivery of surgical care are gaining prominence in the medical literature and media. Concurrently, there is an unprecedented groundswell in idealism and interest in global health among North American medical students and trainees in anesthesia and surgical disciplines. Many academic medical centers (AMCs) are seeking to respond by creating partnerships with teaching hospitals overseas. In this article we describe six such partnerships, as follows: (1) University of California San Francisco (UCSF) with the Bellagio Essential Surgery Group; (2) USCF with Makerere University, Uganda; (3) Vanderbilt with Baptist Medical Center, Ogbomoso, Nigeria; (4) Vanderbilt with Kijabe Hospital, Kenya; (5) University of Toronto, Hospital for Sick Children with the Ministry of Health in Botswana; and (6) Harvard (Brigham and Women’s Hospital and Children’s Hospital Boston) with Partners in Health in Haiti and Rwanda. Reflection on these experiences offers valuable lessons, and we make recommendations of critical components leading to success. These include the importance of relationships, emphasis on mutual learning, the need for “champions,” affirming that local training needs to supersede expatriate training needs, the value of collaboration in research, adapting the mission to locally expressed needs, the need for a multidisciplinary approach, and the need to measure outcomes. We conclude that this is an era of cautious optimism and that AMCs have a critical opportunity to both shape future leaders in global surgery and address the current global disparities.

Serums from tumor-bearing patients, cured patients, and normal subjects were examined for antibodies to the separated complement-fixing reactive components of nonvirion antigens of herpesvirus type 1 and type 2. The occurrence of antibodies to the antigens was similar in serums from tumor-bearing patients and cured patients. Antibodies to the antigens were observed among 21 of 24 (87 percent) cervical cancer cases, 44 of 49 (90 percent) laryngeal cancer cases, 15 of 24 (62 percent) cases of squamous cell carcinomas of the head and neck excluding the larynx, 2 of 24 (8 percent) nonsquamous cell cancer cases, and 3 of 51 (6 percent) normal subjects. By contrast, no differences were found in the titers of neutralizing antibodies to the virus in serums from laryngeal cancer patients and controls. The observations support an etiologic role of herpesviruses in cervical cancer and in laryngeal cancer, and possibly other squamous cell cancers of the head and neck.

High dose methotrexate as a preoperative adjuvant in the treatment of epidermoid carcinoma of the head and neck: A feasibility study and clinical trial☆

John L. Tarpley; Paul B. Chretien; John C. Alexander; Robert C. Hoye; Jerome B. Block; Alfred S. Ketcham

Thirty patients with operable epidermoid carcinoma of the head and neck were treated with intravenous high dose methotrexate and leucovorin rescue prior to resection. Their clinical courses were compared with those of thirty randomly selected patients matched for tumors site and clinical stage who were treated by surgery alone. No medical or surgical complications associated with methotrexate were encountered. An objective decrease in tumor size (primary lesion or nodal metastases) was noted prior to resection in twenty-three patients (77 per cent). The number of recurrences in the two groups was similar. However, these was a significantly greater disease-free interval in the methotrexate-treated patients (p less than 0.05). No significant differences in survival have been noted to date between the two groups. In view of the absence of complications, the regressions in tumor size, and the increase in postoperative disease-free interval in this trial, evaluation as preoperative adjuvants of higher doses of methotrexate and of other chemotherapeutic agents in combination with methotrexate appears warranted.

IMPORTANCE In 2011, the Accreditation Council for Graduate Medical Education (ACGME) restricted resident duty hour requirements beyond those established in 2003, leading to concerns about the effects on patient care and resident training. OBJECTIVE To determine if the 2011 ACGME duty hour reform was associated with a change in general surgery patient outcomes or in resident examination performance. DESIGN, SETTING, AND PARTICIPANTS Quasi-experimental study of general surgery patient outcomes 2 years before (academic years 2009-2010) and after (academic years 2012-2013) the 2011 duty hour reform. Teaching and nonteaching hospitals were compared using a difference-in-differences approach adjusted for procedural mix, patient comorbidities, and time trends. Teaching hospitals were defined based on the proportion of cases at which residents were present intraoperatively. Patients were those undergoing surgery at hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). General surgery resident performance on the annual in-training, written board, and oral board examinations was assessed for this same period. EXPOSURES National implementation of revised resident duty hour requirements on July 1, 2011, in all ACGME accredited residency programs. MAIN OUTCOMES AND MEASURES Primary outcome was a composite of death or serious morbidity; secondary outcomes were other postoperative complications and resident examination performance. RESULTS In the main analysis, 204,641 patients were identified from 23 teaching (n = 102,525) and 31 nonteaching (n = 102,116) hospitals. The unadjusted rate of death or serious morbidity improved during the study period in both teaching (11.6% [95% CI, 11.3%-12.0%] to 9.4% [95% CI, 9.1%-9.8%], P < .001) and nonteaching hospitals (8.7% [95% CI, 8.3%-9.0%] to 7.1% [95% CI, 6.8%-7.5%], P < .001). In adjusted analyses, the 2011 ACGME duty hour reform was not associated with a significant change in death or serious morbidity in either postreform year 1 (OR, 1.12; 95% CI, 0.98-1.28) or postreform year 2 (OR, 1.00; 95% CI, 0.86-1.17) or when both postreform years were combined (OR, 1.06; 95% CI, 0.93-1.20). There was no association between duty hour reform and any other postoperative adverse outcome. Mean (SD) in-training examination scores did not significantly change from 2010 to 2013 for first-year residents (499.7 [ 85.2] to 500.5 [84.2], P = .99), for residents from other postgraduate years, or for first-time examinees taking the written or oral board examinations during this period. CONCLUSIONS AND RELEVANCE Implementation of the 2011 ACGME duty hour reform was not associated with a change in general surgery patient outcomes or differences in resident examination performance. The implications of these findings should be considered when evaluating the merit of the 2011 ACGME duty hour reform and revising related policies in the future.

Purpose To develop an instrument for measuring moral distress in medical students, measuring the prevalence of moral distress in a cohort of students, and identifying the situations most likely to cause it. Moral distress, defined as the negative feelings that arise when one knows the morally correct thing to do but cannot act because of constraints or hierarchies, has been documented in nurses but has not been measured in medical students. Method The authors constructed a survey consisting of 55 items describing potentially distressing situations. Responders rated the frequency of these situations and the intensity of distress that they caused. The survey was administered to 106 fourth-year medical students during a three-week period in 2007; the response rate was 60%. Results Each of the situations was experienced by at least some of the 64 respondents, and each created some degree of moral distress. On average, students witnessed almost one-half of the situations at least once, and more than one-third of the situations caused mild-to-moderate distress. The survey measured individual distress (Cronbach alpha = 0.95), which varied among the students. Whereas women witnessed potentially distressing situations significantly more frequently than did men (P = .04), men tended to become more distressed by each event witnessed (P = .057). Conclusions Medical students frequently experience moral distress. Our survey can be used to measure aspects of the learning environment as well as individual responses to the environment. The variation found among student responses warrants further investigation to determine whether students at either extreme of moral distress are at risk of burnout or erosion of professionalism.

BACKGROUND Several challenges threaten the traditional premise of graduated independence in general surgery training, leading to a lack of readiness in graduating surgeons. The objective of this study was to determine the factors contributing to faculty decisions to grant residents autonomy in the operating room, the barriers to granting this autonomy, and the factors that facilitate entrustment. STUDY DESIGN An anonymous online survey was distributed to 239 attending surgeons at 7 institutions. Questions consisted of open-ended and structured 5-point Likert scale questions. Descriptive statistics were calculated, and a qualitative analysis of free-text responses was performed to identify emergent themes. RESULTS There were 116 attending surgeons who responded to the survey (49%). Factors most important to increasing resident responsibility and autonomy in the operating room were the residents observed clinical skill and the attending surgeons confidence level with the operation. Factors believed to prevent awarding graduated responsibility and autonomy in the operating room included an increased focus on patient outcomes, a desire to increase efficiency and finish operations earlier, and expectations of attending surgeon involvement by the hospital and patients. Among themes discerned in faculty responses to an open-ended question about the greatest challenges in graduate surgical education, 47% of faculty identified work-hour regulations/time restrictions. Fourteen percent pointed to a change to a shift-work mentality and decreased ownership of responsibility for patients by residents; 13% described a lack of resident autonomy due to increased supervision requirements. CONCLUSIONS This study identified several factors that attending surgeons report as significant limitations to transitioning autonomy to surgical residents in the operating room. These issues must be addressed in a direct manner if progressive graduated responsibility to independence is to occur in the next era of graduate surgical training.

Elective Global Surgery Rotations for Residents: A Call for Cooperation and Consortium

Katrina B. Mitchell; Margaret J. Tarpley; John L. Tarpley; Kathleen M. Casey

BackgroundInternational elective experiences are becoming an increasingly important component of American general surgery education. In 2011, the Residency Review Committee (RRC) approved these electives for credit toward graduation requirements. Previous surveys of general surgery program directors have established strong interest in these electives but have not assessed the feasibility of creating a national and international database aimed at educational standardization. The present study was designed to gain in-depth information from program directors about features of existing international electives at their institution and to ascertain interest in national collaboration.MethodsThis cross-sectional study of 253 United States general surgery program directors was conducted using a web-based questionnaire program.ResultsOf the program directors who responded to the survey, twelve percent had a formal international elective in place at their institution, though 80% of these did not have a formal associated curriculum for the rotation. Sixty percent of respondents reported that informal international electives existed for their residents. The location, length, and characteristics of these electives varied widely. Sixty-eight percent of program directors would like to participate in a national and international database designed to facilitate standardization of electives and educational exchange.ConclusionsIn a world of increasing globalization, international electives are more important than ever to the education of surgery residents. However, a need for standardization of these electives exists. The creation of an educational consortium and database of international electives could improve the academic value of these electives, as well as provide increased opportunities for twinning and bidirectional exchange.

Abstract. This study was undertaken to assess the degree of ubiquity of umbilical hernias (UHs) in Nigerians and to determine if a laissez faire approach to the presence of UHs is justified. A prospective evaluation was conducted of the umbilical area of 4052 Nigerians living in the vicinity of the Baptist Medical Centre (BMCO) in Ogbomoso, Nigeria. The diameter of the fascial defect was measured with the subject supine and the protrusion of the umbilical skin with the subject erect. Subjects were divided into three groups: group 1 (1 month to 18 years old); group 2 (older than 18 years); and group 3 (pregnant women in an antenatal clinic). “Outies” (defined as any protrusion of the umbilical tip past the periumbilical skin) were present in 92% of group 1, 49% of group 2, and 90% of group 3 subjects. UHs (defined as protrusion of at least 5 mm and diameter of at least 10 mm) were present in 23% of group 1, 8% of group 2, and 15% of group 3 subjects. Spontaneous closure of UHs seems to occur until age 14. A retrospective analysis identified 11 patients undergoing emergency operations for UH-related problems during the past 15 years. With a low incidence and 0% mortality rate associated with management of these emergencies, a policy of prophylactic repair is not justified at BMCO. Because most of the children we examined had outies, repair for cosmetic reasons is rarely requested. The only logical indication for repair of UHs at BMCO is incarceration, and this rarely occurs.

Surgical Training, Duty-Hour Restrictions, and Implications for Meeting the Accreditation Council for Graduate Medical Education Core Competencies Views of Surgical Interns Compared With Program Directors

Ryan M. Antiel; Kyle J. Van Arendonk; Darcy A. Reed; Kyla P. Terhune; John L. Tarpley; John R. Porterfield; Daniel E. Hall; David L. Joyce; Sean C. Wightman; Karen D. Horvath; Stephanie F. Heller; David R. Farley

OBJECTIVE To describe the perspectives of surgical interns regarding the implications of the new Accreditation Council for Graduate Medical Education (ACGME) duty-hour regulations for their training. DESIGN We compared responses of interns and surgery program directors on a survey about the proposed ACGME mandates. SETTING Eleven general surgery residency programs. PARTICIPANTS Two hundred fifteen interns who were administered the survey during the summer of 2011 and a previously surveyed national sample of 134 surgery program directors. MAIN OUTCOME MEASURES Perceptions of the implications of the new duty-hour restrictions on various aspects of surgical training, including the 6 ACGME core competencies of graduate medical education, measured using 3-point scales (increase, no change, or decrease). RESULTS Of 215 eligible surgical interns, 179 (83.3%) completed the survey. Most interns believed that the new duty-hour regulations will decrease continuity with patients (80.3%), time spent operating (67.4%), and coordination of patient care (57.6%), while approximately half believed that the changes will decrease their acquisition of medical knowledge (48.0%), development of surgical skills (52.8%), and overall educational experience (51.1%). Most believed that the changes will improve or will not alter other aspects of training, and 61.5% believed that the new standards will decrease resident fatigue. Surgical interns were significantly less pessimistic than surgery program directors regarding the implications of the new duty-hour restrictions on all aspects of surgical training (P < .05 for all comparisons). CONCLUSIONS Although less pessimistic than program directors, interns beginning their training under the new paradigm of duty-hour restrictions have significant concerns about the effect of these regulations on the quality of their training.
