Operative Experience of Residents in US General Surgery Programs: A Gap Between Expectation and Experience

Objective:The purpose of the study was to identify a group of operations which general surgery residency program directors believed residents should be competent to perform by the end of 5 years of training and then ascertain actual resident experience with these procedures during their training. Summary Background Data:There is concern about the adequacy of training of general surgeons in the United States. The American Board of Surgery and the Association of Program Directors in Surgery undertook a study to determine what operative procedures residency program directors consider to be essential to the practice of general surgery and then we measured the actual operative experience of graduating residents in those procedures, as reported to the Residency Review Committee for Surgery (RRC). Methods:An electronic survey was sent to residency program directors at the 254 general surgery programs in the US accredited by the RRC as of spring 2006. The program directors were presented with a list of 300 types of operations. Program directors graded the 300 procedures “A,” “B,” or “C” using the following criteria: A—graduating general surgery residents should be competent to perform the procedure independently; B—graduating residents should be familiar with the procedure, but not necessarily competent to perform it; and C—graduating residents neither need to be familiar with nor competent to perform the procedure. After ballots were tallied, the actual resident operative experience reported to the RRC by all residents finishing general surgery training in June 2005 was reviewed. Results:One hundred twenty-one of the 300 operations were considered A level procedures by a majority of program directors (PDs). Graduating 2005 US residents (n = 1022) performed only 18 of the 121 A procedures, an average of more than 10 times during residency; 83 of 121 procedures were performed on an average less than 5 times and 31 procedures less than once. For 63 of the 121 procedures, the mode (most commonly reported) experience was 0. In addition, there was significant variation between residents in operative experience for specific procedures. In virtually all cases, the mean reported experience exceeded the mode, suggesting that the mean is a poor measure of typical experience. Conclusions:These data pose important problems for surgical educators. Methods will have to be developed to allow surgeons to reach a basic level of competence in procedures which they are likely to experience only rarely during residency. Even for more commonly performed procedures, the numbers of repetitions are not very robust, stressing the need to determine objectively whether residents are actually achieving basic competency in these operations. Finally, the large variations in experience between individuals in our residency system need to be explored, understood, and remedied.

Pelvic fracture from major blunt trauma. Outcome is determined by associated injuries

Pelvic hemorrhage has been implicated as the cause of death in 50% of patients who die following pelvic fractures. To establish correlates of morbidity and mortality from pelvic fractures due to blunt trauma, we reviewed 236 patients treated during 4 years. The average age of the 144 men and 92 women was 31.5 years, the average Injury Severity Score was 21.3, the average blood requirement was 5 units, and the average hospital stay was 16.8 days. One hundred fifty-two patients (64.4%) were injured in motor vehicle accidents, 33 (14%) had motor vehicle-pedestrian accidents, 16 (6.8%) had crush injuries, 12 (5.1%) each had either motorcycle accidents or falls, and 11 (4.6%) had miscellaneous accidents. Eighteen patients (7.6%) died, with seven (38.9%) deaths due to hemorrhage. Only one death was caused by pelvic hemorrhage. Other deaths were due to hemorrhage from other sites (6), head injury (5), sepsis or multiple-organ failure (4), pulmonary injury (1), and pulmonary embolus (1). None of the septic deaths was related to a pelvic hematoma. Multivariate multiple regression analysis showed that the severity of injury was correlated with indices of severity of pelvic fractures such as fracture site (p less than 0.0001), fracture displacement (p less than 0.005), pelvic stability (p less than 0.0001), and vector of injury (p less than 0.01). However death could not be predicted on the basis of these indices of severity (p greater than 0.28). Of the nine patients who underwent pelvic arteriography, three required embolization of actively bleeding pelvic vessels, but seven had intra-abdominal hemorrhage that required laparotomy, and eight developed a coagulopathy. Massive bleeding from pelvic fractures was uncommon, and the major threat of hemorrhage was from nonpelvic sites. Furthermore, although injury severity was correlated with the severity of the pelvic fracture, hospital outcome was determined by associated injuries and not by the pelvic fracture.

Trauma in pregnancy: The role of interpersonal violence

OBJECTIVE Our purpose was to determine what role interpersonal violence as intentional injury plays in the pregnant trauma victim. STUDY DESIGN We performed a retrospective review of medical records. RESULTS During a 9-year period in a single university medical and trauma center, 203 pregnant women were treated for a physically traumatic event. Sixty-four women (31.5%) were victims of intentional injury, in most cases by the husband or boyfriend. Although the mean Injury Severity Score was higher in women with fetal death than in women with successful pregnancy outcomes (7.25 vs 1.74, respectively; p < 0.01), 5 of the 8 women with fetal losses incurred these despite an apparent absence of physical injury (maternal Injury Severity Score = 0). CONCLUSIONS Interpersonal violence during pregnancy is a frequent and increasingly common cause of maternal injury. The inconsistent relationship between Injury Severity Score and serious fetal injury or death is underscored by the loss of 5 fetuses despite an Injury Severity Score of 0.

General surgery workloads and practice patterns in the United States, 2007 to 2009: a 10-year update from the American Board of Surgery.

Objective:To assess changes in general surgery workloads and practice patterns in the past decade. Background:Nearly 80% of graduating general surgery residents pursue additional training in a surgical subspecialty. This has resulted in a shortage of general surgeons, especially in rural areas. The purpose of this study is to characterize the workloads and practice patterns of general surgeons versus certified surgical subspecialists and to compare these data with those from a previous decade. Methods:The surgical operative logs of 4968 individuals recertifying in surgery 2007 to 2009 were reviewed. Data from 3362 (68%) certified only in Surgery (GS) were compared with 1606 (32%) with additional American Board of Medical Specialties certificates (GS+). Data from GS surgeons were also compared with data from GS surgeons recertifying 1995 to 1997. Independent variables were compared using factorial ANOVA. Results:GS surgeons performed a mean of 533 ± 365 procedures annually. Women GS performed far more breast operations and fewer abdomen, alimentary tract and laparoscopic procedures compared to men GS (P < 0.001). GS surgeons recertifying at 10 years performed more abdominal, alimentary tract and laparoscopic procedures compared to those recertifying at 20 or 30 years (P < 0.001). Rural GS surgeons performed far more endoscopic procedures and fewer abdominal, alimentary tract, and laparoscopic procedures than urban counterparts (P < 0.001). The United States medical school graduates had similar workloads and distribution of operations to international medical graduates. Compared to 1995 to 1997, GS surgeons from 2007 to 2009 performed more procedures, especially endoscopic and laparoscopic. GS+ surgeons performed 15% to 33% of all general surgery procedures. Conclusions:GS practice patterns are heterogeneous; gender, age, and practice setting significantly affect operative caseloads. A substantial portion of general surgery procedures currently are performed by GS+ surgeons, whereas GS surgeons continue to perform considerable numbers of specialty operations. Reduced general surgery operative experience in GS+ residencies may negatively impact access to general surgical care. Similarly, narrowing GS residency operative experience may impair specialty operation access.

Surgical approach of choice for penetrating cardiac wounds.

One hundred nineteen patients suffered penetrating cardiac trauma over a 15-year period: 59 had gunshot wounds, 49 had stab wounds, and 11 had shotgun wounds. The overall survival rate was 58%. The most commonly injured structures were the ventricles. Twenty-seven patients had injuries to more than one cardiac chamber. Thirty patients had associated pulmonary injuries. Emergency thoracotomy was performed in 47 patients with 15% survival. Median sternotomy was used in 30 patients with 90% survival. Seventeen of the 83 patients with thoracotomies required extension across the sternum for improved cardiac exposure or access to the contralateral hemithorax. Only one patient with sternotomy also required a thoracotomy. All pulmonary injuries were easily managed when sternotomy was used. We conclude that sternotomy provides superior exposure for cardiac repair in patients with penetrating anterior chest trauma. We feel it is the incision of choice in hemodynamically stable patients. Thoracotomy should be reserved for unstable patients requiring aortic cross-clamping, or when posterior mediastinal injury is highly suspected.

Bloodborne Pathogen Transmission from Healthcare Worker to Patients: Legal Issues and Provider Perspectives

Health-care providers have an obvious, primary obligation to patients. Yet providers also have obligations to the public health (society), their institutional or individual self-interests, and their employees (fellow health-care workers). These obligations contain inherent conflicts, and attempts to reconcile the conflicts often perpetuate contradictions. This article identifies and discusses some of the moral and legal bases of these conflicts.

Motivations to Pursue Fellowships Are Gender Neutral

OBJECTIVE To determine the importance of factors in decision making by general surgery chief residents to pursue fellowships and to relate factor importance to gender and residency characteristics. DESIGN Prospective, voluntary, national survey conducted April through May, 2008, in which finishing chief residents rated the importance of 12 factors in their decision making to pursue fellowships. SETTING General surgery chief residents who applied for admission to the American Board of Surgery Qualifying Examination process. PARTICIPANTS All 1034 first-time applicants. MAIN OUTCOME MEASURES chi(2) tests and 1-way analyses of variance were used to correlate gender and residency type, size, and location with summed values and scaled mean scores for ratings of the importance of 12 potential factors in fellowship decision making. RESULTS The fellowship rate was 77% and correlated with residency size and location. Women were dispersed asymmetrically across residencies overall but future female fellows were distributed similarly to male ones. Survey item response rates for future fellows were 96% to 98%. Clinical mastery and specialty activities were valued most highly by more than 90% of men and women. Men placed more value on income potential and spousal influence. Lifestyle factors reached only midrange importance for both genders. Program size had more significant relationships to decision-making factors than did gender. CONCLUSIONS The ability to master an area of clinical practice and the clinical activities of a specialty are the most important factors for chief residents in fellowship decision making, regardless of gender. Lifestyle factors are of midrange importance. Program size is as influential as is gender.

Replacement of Infected Aortic Prosthetic Grafts with Vascularized Musculofascial Flaps

Infected aortic prosthetic grafts are associated with a high rate of morbidity and mortality. In order to examine an alternative to extraanatomic bypass, a canine model of infected aortic Dacron grafts was used to evaluate a vascularized musculofascial pedicle flap fashioned into a cylinder for aortic reconstruction. The flap consists of rectus muscle, posterior rectus fascia and underlying peritoneum, based on the inferior epigastric artery. Infection was established by direct inoculation of the Dacron grafts after insertion, with 1 × 108 CFU of Staphylococcus aureus. All dogs had swab, culture, and histologic proof of infection of the prosthetic Dacron grafts within 72 hours prior to construction of the flap. Three of the four dogs ecovered after flap insertion with normal activity and normal neurovascular status. Aortogram demonstrated patency of the flap with excellent arterial runoff in all dogs 24 days after construction. None of the flaps showed evidence of infection. One animal is now seven months after flap construction with no difficulties and is being maintained long-term for histological evaluation of the flap. A vascularized musculofascial pedicle flap can be successfully used for replacement of infected aortic tube grafts without the need for extraanatomic bypass.
