The general surgery workforce.

BACKGROUND: The workforce in general surgery has been the subject of studies in 1975 and 1994, as has the input of residency program graduates, their subsequent subspecialization, and the retirement pattern of practicing general surgeons. This study analyzes the distribution of general surgeons in the United States. DATA SOURCES: Certified general surgeons were identified from files of the American Board of Medical Specialties (ABMS). Included were general surgeons with no additional certificates except for Surgical Critical Care. Excluded were surgeons certified only by an osteopathic board, noncertified surgeons, retirees, missionaries, federal employees, and military surgeons. The Area Resource File of the Bureau of Health Professions was used to classify metropolitan and rural areas, and primary care health professions shortage areas (PC-HPSA). CONCLUSIONS: General surgeons are well distributed in the various states. More general surgeons are located in metropolitan than in rural areas, and few general surgeons practice in counties in which the whole county is designated as a PC-HPSA. The ratio of general surgeons to the population is similar to that found in 1975.

Meta-analysis of low molecular weight heparin in the prevention of venous thromboembolism in general surgery.

BACKGROUND: Low molecular weight heparins (LMWHs) have become routine thromboprophylaxis in general surgery. However, their actual clinical effect, its magnitude relative to that of unfractionated heparin (UFH), and the optimal dose are still debated. METHODS: A meta-analysis was performed of all available randomized trials in general surgery comparing LMWH with placebo or no treatment, or with UFH. RESULTS: Comparison versus placebo or no treatment confirmed that the significant reduction in asymptomatic deep vein thrombosis (DVT) obtained with LMWH (n = 513; relative risk (RR) 0.28 (95 per cent confidence interval 0.14-0.54)) was associated with a significant reduction in clinical pulmonary embolism (n = 5456; RR 0.25 (0.08-0.79)) and clinical venous thromboembolism (VTE) (n = 4890; RR 0.29 (0.11-0.73)), and a trend towards a reduction in overall mortality rate. Comparison versus UFH showed a trend in favour of LMWH, with a significant reduction in clinical VTE (P = 0.049), a trend also found for cancer surgery. LMWH at doses below 3400 anti-Xa units seemed to be as effective as, and safer than, UFH, while higher doses yielded slightly superior efficacy but increased haemorrhagic risk, including that of major haemorrhage. CONCLUSION: Asymptomatic DVT may be regarded as a reliable surrogate endpoint for clinical outcome in studies investigating thromboprophylaxis in general surgery. LMWH seems to be as effective and safe as UFH. Determination of the optimal dose regimen of LMWH for this indication requires further investigation.

The increasing workload of general surgery.

BACKGROUND: With the aging of the baby boomers, individuals aged 65 years and older make up the fastest-growing segment of the US population. This aging of the population will lead to new challenges for the US health care system because older individuals are the largest consumers of health care. HYPOTHESIS: The general surgery workload will increase dramatically by 2020 as a result of the aging population. DATA SOURCES: The National Hospital Discharge Survey, National Survey of Ambulatory Surgery, US Census Bureau, and Centers for Medicare and Medicaid Services. SETTING: A nationally representative random sample of inpatient and outpatient general surgical operations performed in 1996 in the United States. METHODS: Age- and procedure-specific rates of general surgery were obtained from the National Hospital Discharge Survey and National Survey of Ambulatory Surgery. Population projections were derived from the census bureau. We used relative-value units as a proxy for surgical work. By linking these 3 data sources, we predicted the future general surgery workload by analyzing the rates of surgery and modeling both the aging and expansion of the population. RESULTS: General surgery operations (n = 63) were classified into 5 procedure categories. Whereas the population will grow by 18% between 2000 and 2020, the workload of general surgeons will increase by 31.5%. The amount of growth (19.9%-40.3%) varies among different categories of operations. CONCLUSIONS: To our knowledge, this is one of the only studies to analyze the future workload of general surgery. We project a dramatic increase in workload in the next 20 years, largely as a result of the aging US population. Our baseline assumptions are relatively conservative, so this forecast may be an underestimation. Hence, the challenge for general surgeons is to develop strategies to address this problem while maintaining quality of care for our patients.

Directed blood donation in pediatric general surgery: Is it worth it?

PURPOSE: To date, there are no data to support the safety, efficacy, and cost-benefit ratio of donor-directed blood donation (DD). The objectives were to determine whether a DD program in pediatric general surgery practice is justified. METHODS: A retrospective analysis was conducted of the transfusion practice and all DD requests received by transfusion services in a full calendar year (1997) at a tertiary care pediatric hospital. The authors examined the donations, utilization, and possible benefits for the recipients. RESULTS: A total of 22,527 units of blood were transfused in 1997. General surgery used 471 (2%) of the total and 471 of 4,825 (10%) of all surgical transfusions. Total DD requests were 219 with only 11 of 219 (5%) originating from the general surgery department. After all the exclusions, 133 of 219 (61%) requests had DD blood available. DD blood had a higher true-positive rate for transmissible disease (1.1% v 0.10%), high-risk activity (2.5% v 1.2%), and malaria risk (3.1% v 0.31%). Total utilization of DD blood was 132 of 236 units (55.9%) and general surgery utilized 4 of 11 (36.4%) of their directed donations. Thirty-seven patients (27.8%) benefited from decreased donor exposure. No general surgery patient received more than 1 blood component to benefit from decreased donor exposure. CONCLUSIONS: DD deferral rates are higher than for volunteer donors for infectious disease markers, malaria, and high-risk activities. There is no evidence that DD is safer than volunteer donation. DD blood wastage of 63.6% is much higher than in volunteer donation (7%). Thirty-seven patients (28%) received multiple units from one donor suggesting a benefit from decreased donor exposure. Given the low frequency of transfusion and the poor utilization of DD in general surgical practice, a DD program is not justified.

General surgery and fellowship training: opinions of surgical intern applicants and fellowship directors.

BACKGROUND: Given the pressures that exist today to modify surgical training programs, this study was undertaken to ascertain the opinions of surgical intern applicants and fellowship program directors with regard to the length of surgical training. METHODS: Surveys were sent to fourth-year medical students who were applying for categorical surgical training during a 2-year period at a single university medical center and to fellowship program directors in 6 surgical subspecialties. RESULTS: Ninety-three percent of the applicants planned to pursue fellowship training. Sixty-eight percent of the applicants did not feel that 5 years of general surgery are necessary before beginning a fellowship. Seventy-one percent of the applicants indicated that they would be willing to "short track" into a subspecialty to reduce training time. Virtually all fellowship directors in pediatric surgery (94%), transplantation surgery (94%), and oncologic surgery (100%) felt that 5 years of general surgery training are necessary before entering a fellowship. Significantly fewer fellowship directors in vascular surgery (53%), cardiothoracic surgery (30%), and plastic surgery (17%) felt that 5 years of general surgery are essential before beginning a fellowship (P < or = .001). CONCLUSIONS: For some general surgery subspecialties, a shortened, integrated training program may be desirable from the point of view of both trainees and fellowship directors. Vascular, cardiothoracic, and plastic surgery appear to be those subspecialties that are most amenable to such programs.

A comparative trial of a low molecular weight heparin (enoxaparin) versus standard heparin for the prophylaxis of postoperative deep vein thrombosis in general surgery.

BACKGROUND: Various studies have been performed in general surgery patients comparing low molecular weight heparin (LMWH) with standard heparin (SH) for the prevention of postoperative deep vein thrombosis (DVT), revealing contradicting results. Therefore, we have compared the efficacy and safety of a LMWH for the prevention of DVT after major general surgery. PATIENTS AND METHODS: Patients received either 20 mg LMWH (enoxaparin) once daily, or 5,000 IU SH TID, starting preoperatively in a prospective, randomized, double-blind international multicenter trial. DVT was diagnosed using fibrinogen I 125 leg scanning. Major and minor bleeding were assessed clinically. RESULTS: A total of 718 patients were randomized to LMWH, and 709 patients to SH. DVT was detected in 58 LMWH-treated patients (8.1%, 95% confidence interval [CI] 6.2% to 10.3%) and in 45 patients allocated to SH (6.3%, 95% CI 4.7% to 8.4%, P > 0.05). Major bleeding complications occurred in 11 LMWH-treated patients (1.5%, 95% CI 0.8% to 2.7%) and in 18 patients to whom standard heparin was administered (2.5%, 95% CI 1.5% to 3.9%, P > 0.05). Four LMWH-treated patients (0.6%) required reoperation for bleeding as compared to 13 patients in the SH group (1.8%, P = 0.03). CONCLUSION: This LMWH appeared as effective and safe as SH. In view of its more convenient way of administration, this LMWH might be preferred for thromboprophylaxis.

Modest serum creatinine elevation affects adverse outcome after general surgery.

BACKGROUND: Modest preoperative serum creatinine elevation (1.5 to 3.0 mg/dL) has been recently shown to be independently associated with morbidity and mortality after cardiac surgery. It is important to know if this association can be applied more broadly to general surgery cases. METHODS: Multivariable logistic regression analyses of 46 risk variables in 49,081 cases from the Veterans Affairs National Surgical Quality Improvement Program, undergoing major general surgery from 10/1/96 through 9/30/98. RESULTS: Thirty day mortality and several cardiac, respiratory, infectious and hemorrhagic morbidities were significantly (P < 0.001) higher in patients with a serum creatinine>1.5 mg/dL. With multivariable analysis, the adjusted odds ratio for mortality for patients with a serum creatinine of 1.5 to 3.0 mg/dL was 1.44 [95% confidence interval (95% CI) 1.22 to 1.71] and for creatinine>3.0 mg/dL was 1.93 (95% CI 1.51 to 2.46). The adjusted odds ratio for morbidity (one or more postoperative complications) for patients with a serum creatinine of 1.5 to 3.0 mg/dL was 1.18 (95% CI 1.06 to 1.32) and for creatinine>3.0 mg/dL was 1.19 (95% CI 0.99 to 1.43). Further stratification and recursive partitioning of creatinine levels revealed that a serum creatinine level>1.5 mg/dL was the approximate threshold for both increased morbidity and mortality. CONCLUSIONS: Modest preoperative serum creatinine elevation (>1.5 mg/dL) is a significant predictor of risk-adjusted morbidity and mortality after general surgery. A preoperative serum creatinine of 1.5 mg/dL or higher is a readily available marker for potential adverse outcomes after general surgery.

Identification of criteria for the prioritisation of patients for elective general surgery.

OBJECTIVE: A single visual analogue scale is used in New Zealand to prioritise patients for elective general surgery. Although it reflects clinical judgement, it has been criticised for its lack of transparency. We wished to elicit generic criteria used by surgeons for prioritisation of patients for elective general surgery in order to improve the transparency of the visual analogue scale. METHODS: Semi-structured interviews were undertaken with 15 general surgeons. Using the repertory grid method, surgeons were asked to explain their rationale for distinguishing between patients they considered a high, medium or low priority for treatment. Interviews were audiotaped, transcribed and analysed for themes. The accuracy of the thematic analysis was checked using a five-point Likert scale to assess surgeons' agreement with the identified themes. Further testing to check for face, content and construct validity was undertaken with a purposive sample of six surgeons prioritising patient vignettes. RESULTS: Eight major themes were deduced: diagnosis; treatment; patient characteristics; symptomatology and sequelae to date; future complications; quality of life; psychological/emotional impact; and socio-political/logistic factors. The utilisation of these themes by surgeons was confirmed. Tests of collinearity indicated good content validity. Factor analysis confirmed the hypothesis of one underlying construct, namely priority. CONCLUSION: Seven of the themes became the basis for a new clinical priority assessment criteria tool using visual analogue scales to determine priority of patients for elective general surgery. Further testing of reliability and validity is needed.

Integrating emergency general surgery with a trauma service: impact on the care of injured patients.

BACKGROUND: There has been considerable discussion on the national level on the future of trauma surgery as a specialty. One of the leading directions for the field is the integration of emergency general surgery as a wider and more attractive scope of practice. However, there is currently no information on how the addition of an emergency general surgery practice will affect the care of injured patients. We hypothesized that the care of trauma patients would be negatively affected by adding emergency general surgery responsibilities to a trauma service. METHODS: Our institution underwent a system change in August 2001, where an emergency general surgery (ES) practice was added to an established trauma service. The ES practice included emergency department and in-house consultations for all urgent surgical problems except thoracic and vascular diseases. There were no trauma staff changes during the study period. Trauma registry data (demographics, injuries, injury severity, and procedures) and performance improvement data (peer-review judgments for all identified errors, denied days, audit filters, and deaths) were abstracted for two 15-month periods surrounding this system change. Chi-square, Fisher's exact, and t tests provided between-group comparisons. RESULTS: The trauma staff evaluated a total of 5,874 patients during the 30-month study. There were 1,400 (51%) trauma admissions in the pre-ES group and 1,504 (48%) in the post-ES group, of which 1,278 and 1,434, respectively, met severity criteria for report to our statewide database (Pennsylvania Trauma Outcome Study [PTOS]). There were 163 (12.7% of PTOS) deaths in the pre-ES group compared with 171 (11.9% PTOS) deaths in the post-ES group (p = not significant [NS]). There was one death determined to be preventable by the peer review process for the pre-ES group, and none in the post-ES group. Both groups had 10 potentially preventable deaths, with the remaining mortalities being categorized as nonpreventable (p = NS). Unexpected deaths by TRISS methodology were 36 (2.8%) and 41 (2.9%) for the two groups, respectively (p = NS). There was no difference in the number of provider-specific complications between the groups (23, [1.8%] vs. 19 [1.3%], p = NS). The addition of emergency surgery has resulted in an additional average daily workload of 1.3 cases and 1.2 admissions. CONCLUSION: Despite an increase in trauma volume over the study period, the addition of emergency surgery to a trauma service did not affect the care of injured patients. The concept of adding emergency surgery responsibilities to trauma surgeons appears to be a valid way to increase operative experience without compromising care of the injured patient.

Applying risk assessment models in general surgery: overview of our clinical experience.

Venous thromboembolism (VTE) is an important complication of general surgery. Epidemiological data demonstrate that the incidence of VTE may exceed 50% in some patient groups in the absence of prophylaxis, but the risk varies widely in different types of general surgery. A large number of concomitant risk factors for VTE have now been identified, including intrinsic patient factors such as older age and a previous history of VTE. Over recent years, several consensus conferences have defined categories for different levels of thromboembolic risk in general surgery based on clinical criteria, and have made prophylaxis recommendations according to the degree of risk. Existing physical and pharmacological methods of prophylaxis, particularly low-molecular-weight heparins, have been shown to be safe and effective in reducing thromboembolic risk to very low levels in the majority of patients undergoing general surgical procedures. However, these measures are currently underused, due both to underestimation of thromboembolic risk and fear of haemorrhage. Furthermore, some patient groups, such as those undergoing neurosurgery or with malignancy, remain at significant risk of VTE despite conventional prophylaxis. More accurate stratification of patients for thromboembolic risk, using evidence-based prophylaxis recommendations may lead to improved thrombosis prevention. Validation of independent thromboembolic risk factors and risk assessment models will assist in patient stratification, and allow identification of very-high-risk patients. Novel anticoagulant therapies currently under development may offer a superior antithrombotic:haemorrhagic ratio, providing improved protection in very-high-risk patients.

[Evaluation of the effectiveness and safety of Fragmin (Kabi 2165) versus calcium heparin in the prevention of deep venous thrombosis in general surgery].

Fourty patients who underwent general surgery have been enrolled in a double-blind controlled trial which evaluated the efficacy and safety of Fragmin, a new low molecular weight heparin, chosen to be the 1st OMS International Standard for LMWH. Fragmin 2500 UI anti-Xa once daily and unfractionated heparin 5000 UI twice daily were administered to prevent postoperative deep venous thrombosis. Prophylaxis began two hours before surgery and continued for the next 5 postoperative days. The incidence of isotopic venous thrombosis, thromboembolic disorders and bleeding complications have been evaluated. Results have shown a similar efficacy and safety profile of the two drugs, although Fragmin doses are markedly inferior to unfractionated heparin's. Moreover, Fragmin has the advantage of a single daily administration, with a better patients' compliance and an easier and less expensive nursing care.

[Topical use of antibiotics for preventing wound infection in general surgery].

A group of 463 general surgery patients received topical applications of lincomycin and gentamycin, which significantly reduced the incidence of infected wounds compared to the untreated control group. This confirmed the prophylactic efficacy of topical antibiotic treatment which is also less dangerous than parenteral administration.

[Recording of the surgical procedures and postoperative complications in general surgery].

With selected examples from general surgery, a better statistical elaboration of patient's data by means of operation and complication classification is demonstrated. The use of an operation and a complication key is presented. The advantage of such a classification key in documentation is the possibility of maintaining an accurate yearly review of all therapeutical methods in surgery.

The role of the emergency medicine resident using the Alvarado score in the diagnosis of acute appendicitis compared with the general surgery resident.

PURPOSE: To compare the accuracy of diagnosing appendicitis between emergency medicine residents using the Alvarado score and general surgery residents using ultrasonography and their clinical provision. METHODS: A total of 358 patients (192 men and 166 women) were admitted to the emergency service with suspected appendicitis. Each patient was evaluated by an emergency medicine resident and then by a general surgeon independently. Age, sex, operational data, diagnosis, and the Alvarado scores were measured. RESULTS: The sensitivity and specificity of the Alvarado score were 95.4% (95% confidence interval 91-99%) and 45.7% (95% confidence interval 37.4-54%), respectively. There was a significant difference between the sexes in the predictive values of a positive test (P=0.045) and a negative test (P=0.02). There was no statistical difference between the emergency medicine residents and general surgery residents in terms of positive and negative predicitive values (P>0.05 each). CONCLUSION: There was no statistical difference between the emergency medicine residents using the Alvarado score and the general surgery residents in terms of suspecting the diagnosis of appendicitis.

Use of autologous blood in general surgery.

BACKGROUND/AIMS: Autologous blood predonation is still not as widespread as it should be in general surgery practice, even if the method is well-known and has benefits established in international literature. Authors describe the impact of an autotransfusion program, in a general surgery university department, focusing on management and cost problems. METHODOLOGY: A description of the efficacy of the program during a yearlong activity period is presented. An analysis has been made about the quantity of predonated blood/plasma units, the quantity actually transfused and use of homologous blood. The problems which occurred and the cost are discussed. RESULTS: The most used autotransfusion method was preoperative predeposit of autologous blood. The analysis of results focused on some organizational problems that need to be avoided in order to show the methods maximum benefits. In a large number of cases (some 50%) predeposit was not made because of several managing/technical problems. In another large number of cases (38%) the quantity of units predonated did not fully supply the needs and several patients received homologous products. In another number of cases predonated blood units were not used at all (61/34%). CONCLUSIONS: Predeposit, preoperative hemodilution and intraoperative recovery, are methods that should all be available in a general surgery department to manage in the best way the single patients blood/plasma needs, reducing post-transfusion complication. To optimize the program and minimize waste some guidelines must be established, with the aim of a rational and correct use of the procedure. Despite the value of the method, and the favor encountered by the patients, we must not forget that the use of autologous blood is not costless.

Career pathways of graduates of general surgery residency programs: an analysis of graduates from 1983 to 1990.

BACKGROUND: Approximately 1,000 individuals complete graduate surgical education in general surgery each year. Their subsequent career pathways have not been described but may have relevance to the supply of general surgeons available to provide a broad range of surgical care to the population of the USA. STUDY DESIGN: Data for this study were obtained from the American College of Surgeons's Surgery Resident Masterfile, developed for the annual Longitudinal Study of Surgery Residents, and the American Board of Medical Specialties's Official Directory of Board Certified Medical Specialists. For verification purposes, the American Medical Association's Physician Masterfile and the American Board of Surgery's certified database were searched. Yearly analyses of certified general surgery graduates from 1983 to 1990 were conducted, and rates of certification between US or Canadian medical school graduates and international medical school graduates (IMG) were compared. RESULTS: Ten to 18 years after completion of a residency program in general surgery, 93.6% of graduates had been certified in general surgery or by another American Board of Medical Specialties board. A total of 43.7% of the 8,068 graduates were certified, in addition, in a general surgery-based specialty. Overall, evidence of certification was not available for 6.4% of graduates. The certification rate for US or Canadian graduates was 95.8% of general surgeons and increased for IMG surgeons from 69.4% for 1983 graduates to 94.7% for 1990 graduates. The number of IMGs in general surgery residency programs declined from 19.7% of 1983 graduates to 7.8% of 1990 graduates. The rates of American Board of Surgery certification are 96.1% for male and 93.6% for female US or Canadian graduates; 79.2% of male IMG graduates and 83.7% of female IMG graduates became certified. CONCLUSIONS: Most surgeons who completed a general surgery residency program from 1983 to 1990 are certified and presumably have met high standards for knowledge and experience. More than half of the graduates specialize further.

Brief communication of the Residency Review Committee-Surgery (RRC-S) on residents' surgical volume in general surgery.

BACKGROUND: The Residency Review Committee-Surgery (RRC--S), 1 of 10 surgical specialties of the Accreditation Council for Graduate Medical Education (ACGME) has monitored the surgical volume of all general surgical residents closely. As a consequence of the reduction of duty hours with the limitation of an 80-hour work-week (averaged over 4 weeks), we were interested in the impact of these restrictions on surgical (volume) experience since its first year of implementation (2003--2004). Therefore, we evaluated the surgical volume of general surgical services since the implementation of the ACGME duty-hour restrictions and compared this volume with that of previous years without these duty limits. METHODS: The Biostatistical Management Section of the ACGME implemented prospective analysis of categorized data for total surgical procedures and Chief Resident cases. The study interval included all resident surgical procedures completed from 1997 to 2004. We were interested particularly in evaluating trends and outcomes after the first year of successful full compliance of the 80-hour work week. Specific evaluations included the impact on surgical programs for total major procedures and Chief Resident cases requisite for application to the American Board of Surgery. RESULTS: The average number of total major procedures for both resident and program averages were noted to increase steadily through the academic years of evaluation (1997--2001). A sharp decrease was evident in the total major procedures for the academic year 2001--2002 that relates to a correction of the biostatistical database implemented by the ACGME to correct a system conversion that began in the academic year 2001--2002. Despite significant changes to the system data mappings, beginning in the academic year 2001, this reduction is explained by the total counted surgeries as major that were eliminated in a revised counting methodology. It was evident on evaluation of the average (of averages) for major surgical procedures per resident (per program) in academic years 1997 to 2004 that the number of procedures was not statistically different in the academic years evaluated when compared with the year for implementation of duty-hour standards (2003--2004). Data analysis further indicates that the average procedures (per resident) performed as Chief Resident in general surgery remained stable from 1997 to 2004; the use of tiered t tests comparing Chief Resident averages (per program) for the academic years 2002--2003 versus 2003--2004 indicated that data remained consistent and confirmed no statistical variance in volumes during this interval (P=0.43). Because some general surgery programs have exceptions for duty-hour requirements (n=15) to allow an 88-hour week averaged over 4 weeks, these differences were of interest to evaluate programs with and without these duty-hour exceptions. Preliminary data with these limited parameters of evaluation suggest no detrimental outcomes related to the duty-hour restrictions for total major procedures per resident or for surgical procedures as Chief Residents for programs with and without these approved exceptions. CONCLUSIONS: RRCs that evaluate general surgery and surgical specialties have responded aggressively and professionally to implement the duty-hour standards per the ACGME. This brief report should be considered an interim communication to evaluate the surgical experience impact for programs currently under the restriction of duty-hour limits. The data provided in the first year of evaluation since the implementation of the 80-hour work-week restriction policy suggest that there has been no significant change in the overall surgical experience for major procedures (per resident), nor has there been a negative impact on Chief Resident surgical experience. A continuum of the prospective evaluation process is required by the RRC-S and other surgical specialties to ensure that requisite surgical volume is maintained throughout the entire 5 years of clinical surgery.
