Ventricular shunting for hydrocephalus in children: patients, procedures, surgeons and institutions in English Canada, 1989-2001.

INTRODUCTION AND PURPOSE: Ventricular shunting remains the principle and most generally applicable method to treat hydrocephalus in children. This paper describes the demographics of this treatment in English Canada during the period of 1989 to March 2001. METHODS: Hospital discharge records were obtained for patients less than 18 years who had a shunt inserted or revised. A database was constructed relating patients and procedures to hospital discharges based on scrambled patient identifiers, year of birth, sex, postal code and diagnoses. OBSERVATIONS: 5,947 patients underwent ventricular shunting procedures for hydrocephalus in this period. 261 surgeons working in 73 institutions provided 12,106 interventions (Shunt insertions: ventriculoperitoneal--5009, ventriculoatrial--119, ventriculopleural--28. Revisions: 6,950). Infection was deemed to have occurred in 1,059 procedures. Over the study period, the median number of procedures performed per surgeon per year was 2, with 75 % of surgeons performing 5 or fewer procedures in children per year. Although many surgeons operated on children throughout the thirteen years of the study, many did not acquire substantive cumulative experience. Overall infection rate was 8.6 %. Surgeon infection rates were greater than or equal to 20 % during the first four years of practice and thereafter they fell to and remained in the 10 % range. The mean shunt survival at 12 months of individual surgeons varied between 50 - 60 %, regardless of the number of years of experience of the surgeon; however, performance variability as measured by the standard deviation of 12 month survival rates for all surgeons, adjusted for years of experience, ranged widely until the fifth year of practice. The average number of procedures per year for treating hospitals was 2 with 75 %, providing 12 or fewer services annually. Over the entire study, 50 % of institutions provided 10 or fewer procedures. The mean institutional infection rate was 11.4 % (SD 23, median--6.0). CONCLUSIONS: Quality monitoring of infection rate and duration of shunt function remains critical as many surgeons and hospitals provide care to children with hydrocephalus infrequently. Variability in infection rates and shunt survival at 12 months are a function of surgeon experience, measured by years in practice. Variability in outcome decreases with increasing surgeon experience.

Relation between surgeons' practice volumes and geographic variation in the rate of carotid endarterectomy.

We examined the relation between the number of operative procedures carried out by individual surgeons and the variation in the rate of carotid endarterectomy among Medicare beneficiaries in areas of high, average, and low use of the procedure in 1981. Rates ranged from 48 per 100,000 in the low-use area to 178 per 100,000 in the high-use area. Two variables accounted for most of the differences in the rates: the number of surgeons performing the procedure and the number of endarterectomies performed by surgeons with high practice volumes. Twice as many surgeons in the high-use area and 25 percent more in the average-use area performed carotid endarterectomy as compared with those in the low-use area. If the average number of cases per surgeon had been the same, the differences in the number of surgeons would have accounted for 36 percent and 15 percent, respectively, of the differences in use. Surgeons who performed 15 or more carotid endarterectomies during the year accounted for most of the variation in the rates. These high-volume surgeons represented 15 percent and 17 percent of the surgeons in the areas of high and average use, respectively, as compared with 4 percent of those in the low-use area. They accounted for 60 and 77 percent, respectively, of the additional endarterectomies. Three fourths of the surgeons performing carotid endarterectomies carried out fewer than 10, and 24 percent did only 1. We conclude that most of the geographic variation in the rate of carotid endarterectomy is caused by a few surgeons in high-use areas who perform large numbers of operations.

Vascular surgeons--do they make a difference in peripheral vascular disease?

BACKGROUND: The purpose of this study was to quantitate the effect of surgeons with added qualifications in general vascular surgery on aortic and peripheral vascular surgery performed in a community hospital. METHODS: We performed a retrospective study covering a 22-year period and comparing indications, procedures, and results of surgeons who had added qualifications in general vascular surgery with those of board certified general and thoracic surgeons in a private hospital. In Period I (1975-1982), there were 702 vascular procedures all performed by thoracic (65%) and general (35%) surgeons. In Period II (1982-1997), there were 2590 vascular procedures performed by vascular surgeons (73%), general surgeons (7%), and thoracic surgeons (20%). A further comparison was done to examine the results of surgeons with added qualifications in general vascular surgery with board certified general and thoracic surgeons within Period II. RESULTS: The volume and frequency of different types of vascular surgery changed significantly from Period I to Period II with lower extremity prosthetic reconstructions decreasing from 12% to 8.2% and autogenous lower extremity bypasses increasing from 15% to 36%. The percentage of distal reconstructions increased significantly from 27% of the total vascular surgeries in Period I to 44.3% in Period II. In Period II, vascular surgeons operated on older patients, had decreased mortality, decreased length of stay, and performed more distal bypasses than board certified general and thoracic surgeons. CONCLUSIONS: The development of vascular surgery as a separate specialty appears to have had a beneficial effect on the types of vascular surgery and the results when compared in a contemporaneous or retrospective fashion.

Work loads and practice patterns of general surgeons in the United States, 1995-1997: a report from the American Board of Surgery.

OBJECTIVE: To characterize the work loads and practice patterns of general surgeons in the United States over a 3-year period (1995 to 1997). METHODS: The surgical operative logs of 2434 "generalist" general surgeons recertifying in surgery form the basis of this report. Selected demographics of the group are as follows: location: 50% Northeast and Southeast, 21 % Midwest, 29% West and Southwest; practice type: 45% solo, 40% group, 9% academics; size of practice community: 46% highly urban, 19% rural. Parameters evaluated were the average number of procedures and their distribution by category related to geographic area, practice type, community size, and other parameters. Statistical analysis was accomplished using analysis of variance. RESULTS: No significant year-to-year differences were observed between cohorts. The average numbers of procedures per surgeon per year was 398, distributed as follows: abdomen 102, alimentary tract 63, breast 54, endoscopic 51, vascular 39, trauma 6, endocrine 4, and head and neck, 3. Eleven percent of the 398 procedures were performed laparoscopically. Major index cases were largely concentrated with small groups of surgeons representing 5% to 10% of the total. Significant differences were as follows: surgeons in the Northeast and West performed far fewer procedures than those elsewhere. Urban surgeons performed a few more tertiary-type procedures than did rural ones; however, rural surgeons performed many more total procedures, especially in endoscopy, laparoscopy, gynecology, genitourinary, and orthopedics. Academic surgeons performed substantially fewer total procedures as a group than did nonacademic ones and in all categories except liver, transplant, and pancreas. Male surgeons performed more procedures than did female surgeons, except those involving the breast. More procedures were done by surgeons in group practice than by those in solo practice. U.S. medical graduates and international medical graduates had similar work loads but with a different distribution. CONCLUSIONS: This unique database will be useful in tracking trends over time. More importantly, it demonstrates that general surgery practice in the United States is extremely heterogeneous, a fact that must be acknowledged in any future workforce deliberations.

Trauma and emergency surgery: an evolutionary direction for trauma surgeons.

BACKGROUND: The success of nonoperative management of injuries has diminished the operative experience of trauma surgeons. To enhance operative experience, our trauma surgeons began caring for all general surgery emergencies. Our objective was to characterize and compare the experience of our trauma surgeons with that of our general surgeons. METHODS: We reviewed records to determine case diversity, complexity, time of operation, need for intensive care unit care, and payor mix for patients treated by the trauma and emergency surgery (TES) surgeons and elective practice general surgery (ELEC) surgeons over a 1-year period. RESULTS: TES and ELEC surgeons performed 253 +/- 83 and 234 +/- 40 operations per surgeon, respectively (p = 0.59). TES surgeons admitted more patients and performed more after-hours operations than their ELEC colleagues. Both groups had a mix of cases that was diverse and complex. CONCLUSION: Combining the care of patients with trauma and general surgery emergencies resulted in a breadth and scope of practice for TES surgeons that compared well with that of ELEC surgeons.

Surgeon experience and clinical and economic outcomes for shoulder arthroplasty.

BACKGROUND: Previous studies have demonstrated that a high surgical volume for certain surgical procedures reduces morbidity and improves economic outcome; however, to our knowledge, no study has demonstrated a similar relationship between volume and outcome for total shoulder arthroplasty and hemiarthroplasty. The objective of this study was to determine whether increased surgeon experience was associated with improved clinical and economic outcomes for patients undergoing total shoulder arthroplasty or hemiarthroplasty. METHODS: We analyzed discharge data on patients treated between 1994 and 2000 from the Maryland Health Services Cost Review Commission, which has a statewide hospital discharge database of all patients in the state of Maryland. The database included all patients undergoing total shoulder arthroplasty and hemiarthroplasty. We assessed the relationship between surgeon volume (low, medium, and high) and the risk of complications, length of stay, and total charges. The statistics were adjusted for procedure, age, gender, race, marital status, comorbidity, diagnosis, insurance type, income, and hospital volume. RESULTS: For the 1868 discrete total shoulder arthroplasties and hemiarthroplasties done in the state of Maryland, the risk of at least one complication associated with the procedures done by the high-volume surgeon group was nearly half that associated with the procedures done by the low-volume surgeon group (adjusted odds ratio, 0.6; 95% confidence interval, 0.4 to 0.9). High-volume surgeons were three times more likely than were low-volume surgeons to have patients with a hospital stay of less than six days (odds ratio, 0.3; 95% confidence interval, 0.2 to 0.6). Although the average cost of hospitalization was $1000 less in the high-volume surgeon group compared with the low-volume surgeon group, this reduction did not reach significance after adjustment for multiple variables (odds ratio, 0.8; 95% confidence interval, 0.5 to 1.4). CONCLUSIONS: This study indicates that the patients of surgeons with higher average annual caseloads of total shoulder arthroplasties and hemiarthroplasties have decreased complication rates and hospital lengths of stay compared with the patients of surgeons who perform fewer of these procedures. These analyses of hospital discharge data are limited because of a lack of prospective data, operative details, and patient outcomes data. However, this study emphasizes the importance of continued education for orthopaedic surgeons who perform shoulder arthroplasty.

Association between hospital and surgeon procedure volume and the outcomes of total knee replacement.

BACKGROUND: The annual volume of major cardiovascular and oncologic procedures performed in hospitals and by surgeons has been inversely associated with the rates of perioperative mortality and complications. The relationship between hospital and surgeon volume and perioperative outcomes following total knee replacement has received little study. METHODS: We analyzed claims data for Medicare patients who had elective primary total knee replacement between January 1 and August 31, 2000. Hospital and surgeon volumes were defined as the number of primary and revision total knee replacements performed in the hospital or by the surgeon in Medicare recipients in 2000. We examined the associations between the annual volumes of total knee replacement performed in the hospitals and by the surgeons and the rates of mortality and complications (infection, pulmonary embolus, myocardial infarction, or pneumonia) in the first ninety days postoperatively. The analyses were adjusted for age, gender, comorbid conditions, Medicaid eligibility (a marker of low income), and arthritis diagnosis. Analyses of hospital volume were adjusted for surgeon volume and vice versa. RESULTS: Twenty-five percent of the primary total knee replacements were done by surgeons who performed twelve of these procedures or fewer in the Medicare population annually, and 11% were done in hospitals with an annual volume of twenty-five of these procedures or fewer. Compared with the patients who had a primary total knee replacement in hospitals with an annual volume of twenty-five procedures or fewer, those managed in hospitals with an annual volume exceeding 200 procedures had a lower risk of pneumonia (odds ratio, 0.65; 99% confidence interval, 0.47 to 0.90) and any of the adverse outcomes examined (death, pneumonia, pulmonary embolus, acute myocardial infarction, or deep infection) (odds ratio, 0.74; 99% confidence interval, 0.60 to 0.90). Similarly, patients who had a primary total knee replacement done by surgeons who performed more than fifty such procedures in Medicare recipients annually had a lower risk of pneumonia (odds ratio, 0.72; 99% confidence interval, 0.54 to 0.95) and any adverse outcome (odds ratio, 0.81; 99% confidence interval, 0.68 to 0.98) compared with patients of surgeons with an annual volume of twelve procedures or fewer. CONCLUSIONS: Patients managed at hospitals and by surgeons with greater volumes of total knee replacement have lower risks of perioperative adverse events following primary total knee replacement. Patients and clinicians should incorporate these findings into discussions about selecting a surgeon and a hospital for total knee replacement. These data should also be integrated into the policy debate about the advantages and drawbacks of regionalizing total joint replacement to high-volume centers.

Variation in orthopaedic surgeons' perceptions about the indications for rotator cuff surgery.

BACKGROUND: Epidemiologic studies have demonstrated substantial variations in per capita rates of many surgical procedures, including rotator cuff repair. The purpose of the current study was to characterize orthopaedic surgeons' attitudes concerning medical decision-making about rotator cuff surgery and to investigate the associations between these beliefs and reported surgical volumes. METHODS: A survey was mailed to randomly selected orthopaedic surgeons listed in the American Academy of Orthopaedic Surgeons directory. Only individuals who had treated patients for a rotator cuff tear, or had referred patients for such treatment, within the previous year were asked to complete the two-page survey. The survey comprised fifteen questions regarding clinical opinion, including four regarding hypothetical cases. Clinical agreement was defined as >80% of the respondents answering similarly. RESULTS: Of the 1100 surveys that were mailed, 539 were returned (a response rate of 49%). Of the 539 respondents, 316 (58.6%) had treated or referred patients with a rotator cuff tear in the previous year. There was a significant negative correlation between the surgeon's estimation of the failure rate of cuff repairs in the United States and that surgeon's procedure volume (r = -0.21, p = 0.0003), indicating that surgeons with a lower procedure volume are more pessimistic about the results of surgery than are those with a higher procedure volume. Arthroscopic, mini-open, and open cuff repairs were preferred by 14.5%, 46.2%, and 36.6% of the respondents, respectively. Surgeons who performed a higher volume of procedures were less likely to perform open surgery (p < 0.0001). There was clinical agreement regarding only four of the nine clinical questions and none of the four questions about the hypothetical vignettes. CONCLUSIONS: We found significant variation in surgical decision-making and a lack of clinical agreement among orthopaedic surgeons about rotator cuff surgery. There was a positive correlation between the volume of procedures performed by the surgeon and the surgeon's perception of outcome, with surgeons who had a higher procedure volume being more enthusiastic about rotator cuff surgery than those who had a lower procedure volume.

The influence of gender of the surgeon on surgical procedure preference for breast cancer.

There are few data in the literature with regard to the influence of surgeon gender and the treatment of breast cancer. In this retrospective review we propose to test the hypothesis that male surgeons are just as likely as female surgeons to provide breast-conservative treatment. From 1990 through 1997 2271 women with breast cancer in Cincinnati, Ohio were operated on by surgeons within the TriHealth Corporation. We compared the performance rate of breast conservation therapy (BCT) with the rate of mastectomy in early-stage breast cancer patients between male and female surgeons. Male surgeons were significantly more likely to provide their patients with breast-conserving treatment than their female colleagues for stages 0 and IIb (P < 0.05). Although male surgeons performed more BCT than female surgeons for stages I and IIa the difference was not statistically significant. For the three stages combined there was a 30 per cent greater chance of a patient receiving breast-conserving treatment if she went to a male surgeon (P < 0.05). We conclude that in our institution male surgeons are no more likely to select mastectomy than their female colleagues and there appears to be an increased use of BCT by male surgeons.

[Surgeons, midwives and physicians in Senta in the 18th and 19th centuries].

INTRODUCTION: Authors present history data on development of the medical profession in Prussia, Germany, Austria and Hungary, that is countries from which surgeons, midwives and physicians most often came to work in Senta. It has been established that mostly junior physicians and "surgeons" came to our country, and from the forties till nineties of the 19th century they made a considerable number of our first medical professionals. In 1872 a law was passed according to which only doctors of medicine with university degrees were allowed to practice medicine, and so junior physicians gradually disappeared. OUR INVESTIGATIONS AND DATA: The earliest data on health care of Senta date back to the tax register for 1771 according to which the expenditure for November contained expenses for bread and half of the allowance for fodder which were paid to the city surgeon. According to the census from 1774/75 the first registered barber surgeon was Mihalj Nad, whereas four years later he was advertised as a surgeon in the tax register. In the following years more surgeons were registered: Janos Grubanovic, Jozef Forgac, Antal Kovac and Johan Brun. The first city midwife registered in the city court record in 1794 was Doroteja Gubik. During 18th century at the territory of Senta only barbers and surgeons were known, and there were no graduated physicians. The first city physician who received a degree from the School of Medicine was Samuel Borod who started working in Senta on April 24, 1822. After that, during 19th century the following physicians worked in Senta: Dr. Laslo Eres, Dr. Jozef Cendic, Dr. Simon Slezinger, Dr. Janos Nepomuki Revai, Dr. Zigmund Veksler, Dr. Adolf Glikstal, Dr. Jozef Kelner, Dr. Mor Lendvai, Dr. Sandor Meri, Dr. Jozef Havel and Dr. Jozef Rejcer. Dr. Janos Nepomuki Revai was at the head of the public health care of our town for 40 years, whereas his predecessor Dr. Jozef Cendić was engaged in this honorable profession for 30 years. Dr. Janos Revai was an outstanding person who introduced vaccination against smallpox and diphtheria, prevented further spreading of trachoma, stopped a great epidemic of cholera in 1892/93 and continually worked on promotion and improvement of health care in Senta. During 19th century the following surgeons worked in Senta: Istvan Budai, Mihajlo Zivković, Jozua Veksler, Istvan Kalman, while the last surgeon working in Senta was Lajos Kuti. In the 19th century the following midwives were registered in Senta: Apolonija Hauser, Verona Kremzer, Regina Zinger, Jozefa Vig, Apolonija Bauc, Apolonija Hauber and Rozalija Huska. At the end, authors list all surgeons, midwives and physicians with complete data on them from all available documents.

Hospital and surgeon determinants of carotid endarterectomy outcomes.

BACKGROUND: Prior studies have found associations between surgeon and hospital case volumes and outcomes after carotid endarterectomy (CEA), but they have not simultaneously assessed the importance of a number of surgeon and hospital characteristics. OBJECTIVE: To simultaneously assess associations between hospital case volume, teaching status, clinical trial participation, and surgeon specialty and case volume and the outcome after CEA. DESIGN: Analysis of a large administrative data-base using logistic regression to correlate adverse outcomes after CEA with surgeon and hospital characteristics. SETTING AND PATIENTS: A Canadian administrative hospital discharge database of all patients undergoing CEA in fiscal years 1994 through 1997. MAIN OUTCOME MEASURES: In-hospital stroke and/or death. RESULTS: We found an inverse relationship between both hospital and surgeon case volumes and adverse outcomes. Teaching status had no association with outcome, but previous clinical trial participation predicted a better outcome. General surgeons fared worse than other specialists. Low-volume surgeons in low-volume hospitals had a relative risk of 3.5 for adverse outcomes compared with high-volume surgeons in high-volume hospitals. CONCLUSIONS: Several physician and hospital characteristics are determinants of outcome after CEA, but the negative effects of low hospital and surgeon case volumes, in particular, suggest that regionalization should be considered for CEA and that surgeons with low case volumes should not be performing CEA.

Effect of surgeon expertise on the outcome in primary hyperparathyroidism.

BACKGROUND: Success in surgery for primary hyperparathyroidism (PHPT) is thought to be closely linked to surgical expertise. We investigated the effect of the surgeon's experience on the postoperative outcome in patients with PHPT. DESIGN: Cohort study with retrospective analysis. SETTING: University tertiary care center. PATIENTS: Two hundred thirty consecutive patients with PHPT. We excluded patients with prior cervical surgery, parathyroid carcinoma, multiple endocrine neoplasia types 1 and 2, and renal hyperparathyroidism. INTERVENTIONS: All 230 patients underwent bilateral neck exploration for PHPT. MAIN OUTCOME MEASURES: We registered complication rates, fulfillment of predefined operative concepts, and operative time in 230 cervical revisions for PHPT and compared the results of experienced surgeons (40 or more cervical revisions for PHPT performed before 1988) with those of surgeons still in training. RESULTS: Two surgeons classified as experienced operated on 75 patients. Under supervision of these surgeons, most operative procedures (n=155) were performed by 12 different surgeons classified as less experienced. Complications were observed in 31 patients (13.5%) with no statistical difference between the specialists and the less-experienced surgeons (P=.85). The ability to demonstrate 4 or more parathyroid glands was significantly increased for the specialists (74.7% vs 51.6%; P<.001), who also terminated the operation earlier (average, 15 minutes; P<.001). CONCLUSION: In an analysis of 230 operations for PHPT in patients without prior neck surgery, no effect of the surgeon's experience on postoperative outcome was demonstrated. Under the supervision of experienced endocrine surgeons, less-experienced surgeons perform cervical revisions for PHPT with comparable results, although with longer operating time.

Surgeon compensation and motivation.

HYPOTHESIS: Financial incentives are the only form of compensation that will motivate surgeons at an academic health sciences center to perform the tasks outlined in the hospital's mission statement. DESIGN: A questionnaire divided into 5 sections: demographics, compensation, time allocation, benefits and incentives, and motivational factors. SETTING: The Department of Surgery, The Toronto Hospital, Toronto, Ontario. PARTICIPANTS: All academic surgeons (N=64) practicing at The Toronto Hospital in July 1997. RESULTS: Of the 64 eligible mailed surveys, there were responses for 59. Of these 59 surgeons, 48 (81%) receive compensation through a fee-for-service method. However, only 32 (54%) of the surgeons prefer the fee-for-service method, while 18 (31%) prefer salary and 9 (15%) prefer an alternative system. On average, these academic surgeons spend 44% of their time teaching or performing research, for which they receive 14% of their total income. Of the motivational factors assessed, financial bonuses are a positive motivational factor for all "surgeon tasks." In addition, task-specific motivational factors were established for research, teaching, and operating, including research facilities, mentorship and prestige, and interesting case types, respectively. CONCLUSIONS: Surgeons are not appropriately renumerated for time spent on academic activities, and many would prefer an alternative form of compensation to the fee-for-service method. Knowledge that surgeons are receptive to tasks supporting the hospital's mission statement leads us to conclude that appropriate motivation can shape the activity of academic surgeons. Financial rewards ranked the highest as a motivational factor for all surgeon tasks; however, task-specific motivational factors were identified. Overall, multiple factors, specifically targeted to the individual, will serve to motivate. Thus, compensation packages based on individual preferences and personal motivational factors will be the most successful.

Effect of surgeon and hospital characteristics on outcome after pyloromyotomy.

BACKGROUND: Previous studies have suggested that the outcome after pyloromyotomy is improved with increased surgeon experience. Others have proposed that infants with pyloric stenosis are best treated by specialty-trained pediatric surgeons or at children's hospitals. HYPOTHESIS: Surgeon and hospital characteristics affect complications, length of stay, and hospital charges after pyloromyotomy. DESIGN: Data for a nationally representative sample of infants (n = 1277) who underwent pyloromyotomy in 2000 in the United States were obtained from the Kids' Inpatient Database. Surgeon and hospital volumes were stratified into quintiles. Multivariate analyses were performed to analyze the impact of surgeon and hospital volume on length of stay, charges, and major operative complications using models that accounted for the hierarchical structure of patient-, surgeon-, and hospital-level covariates. RESULTS: No association between surgeon volume and either length of stay or charges was observed. Higher surgeon volume, however, was associated with fewer complications (P<.001). Surgeons with the highest volume had a 90% lower risk of complications than those with the lowest volume. Higher hospital volume was associated with shorter length of stay (P<.001). No association between hospital volume and either charges or risk of complications was observed. CONCLUSIONS: Higher surgeon and hospital volumes are associated with better outcome among infants who are treated for pyloric stenosis. Identification of aspects of medical and surgical treatment that account for this finding may lead to improvement in the outcome of infants undergoing pyloromyotomy.

An evaluation of the American College of Surgeons' ultrasound education program.

BACKGROUND: Ultrasound has a wide variety of applications in surgery, but until recently few surgeons received any formal training in its use. To facilitate incorporation of ultrasound into surgical practice, the American College of Surgeons (ACoS) developed an ultrasound educational program. The purpose of this study was to evaluate the impact and effectiveness of the ACoS ultrasound education program. METHODS: A survey was mailed to all surgeons who had completed at least one of several ultrasound courses offered by the ACoS from 1998 to 2002. RESULTS: A total of 1,791 surveys were mailed out and 873 completed surveys were returned. Sixty-five percent (576) of respondents reported using ultrasound in their practices after these educational courses. Of those performing ultrasound examinations, 267 did so in one clinical area and 309 in more than one. The most common examination was breast (369 surgeons); vascular, acute/trauma, abdominal, intraoperative/laparoscopic, and head/neck were utilized fairly equally (100-200 surgeons). The number of examinations performed by surgeons before they felt competent was between 11 and 20 and did not vary by the type of ultrasound examination. Of the 267 surgeons performing ultrasound in one clinical area, 176 performed ultrasound-guided procedures. Most surgeons had access to 2 ultrasound machines, but 386 (67%) were restricted from performing ultrasound in certain locations. CONCLUSIONS: The ACoS ultrasound courses are extremely popular and have contributed to the increasing use of ultrasound in surgical practice. Surgeons successfully use ultrasound in their practices including performance of ultrasound-guided procedures but are restricted from using ultrasound in certain patient care areas. Since many surgeons received prior and/or additional training outside of the ACoS, there is a need to facilitate export of ACoS courses to other venues and to focus on incorporating ultrasound training into surgical residency programs.

Credentialing of surgeons as interventionalists for carotid artery stenting: experience from the lead-in phase of CREST.

BACKGROUND: Credentialing of vascular surgeons to perform carotid artery stenting (CAS) continues to be a major issue confronting the specialty of Vascular Surgery. Cannulation of aortic arch branches, and placement of carotid antiembolic devices and stents constitute the major technical challenges to vascular surgeons becoming credentialed to perform CAS. The multicenter Carotid Revascularization Endarterectomy vs Stenting Trial (CREST), supported by the National Institute of Neurological Disorders and Stroke, National Institute of Health, reviews credentials of interventionalists, including surgeons, for the trial's "lead-in" phase of CAS to treat symptomatic (>50% stenosis) and asymptomatic (>70% stenosis). METHODS: Vascular surgeons requesting participation in CREST must have achieved basic interventional credentialing criteria as recommended by the Society of Vascular Surgery. Each interventionalist is asked to submit notes and narrative summaries from a series of 10 to 30 CAS procedures for review by a multi-specialty review committee before being approved to participate in CREST. Thereafter, during the lead-in phase of CREST, each approved interventionalist is asked to perform CAS procedures using the study devices in as many as 20 patients. In this interim report from the CREST lead-phase, the association of specialty of operator (vascular surgeon, neurosurgeon, other specialist) and periprocedural stroke and death rate was examined in patients undergoing CAS. In addition, current enrollment volume in the lead-in phase by specialty of the principal investigator was examined. RESULTS: Thirty-two of 134 (23.9%) CREST-credentialed interventionalists are vascular surgeons (n = 22; 16.4%) or neurosurgeons (n = 10; 7.5%). For events monitored through March 31, 2004, 789 patients had undergone CAS procedures performed by these 134 specialists. Thirty-day stroke and death rate was 4.6%, and myocardial infarction was observed in 1.1% of patients. Serious adverse events have not been clustered at individual institutions, and no significant differences have been observed between vascular surgeons or neurosurgeons and other credentialed specialists. CONCLUSIONS: Vascular surgeons with basic catheter and guide wire skills, particularly those who have incorporated diagnostic cerebral angiography into their practice, can be credentialed to perform CAS. Individuals or groups should devote a number of cases (n = 10-30 per surgeon) to CAS to accomplish this goal. Pending US Food and Drug Administration approval of devices and Center for Medicaid and Medicare Services reimbursement, institutional financial support for the performance of these procedures must be secured. The learning curve for CAS should not be considered so formidable as to discourage surgeons from adding these techniques of CAS to their procedural inventory.

How surgeons disclose medical errors to patients: a study using standardized patients.

BACKGROUND: Calls are increasing for physicians to disclose harmful medical errors to patients, but little is known about how physicians perform this challenging task. For surgeons, communication about errors is particularly important since surgical errors can have devastating consequences. Our objective was to explore how surgeons disclose medical errors using standardized patients. METHODS: Thirty academic surgeons participated in the study. Each surgeon discussed 2 of 3 error scenarios (wrong-side lumpectomy, retained surgical sponge, and hyperkalemia-induced arrhythmia) with standardized patients, yielding a total of 60 encounters. Each encounter was scored by using a scale developed to rate 5 communication elements of effective error disclosure. Half of the encounters took place face-to-face; the remainder occurred by videoconference. RESULTS: Surgeons were rated highest on their ability to explain the medical facts about the error (mean scores for the 3 scenarios ranged from 3.93 to 4.20; maximum possible score, 5). Surgeons used the word error or mistake in only 57% of disclosure conversations, took responsibility for the error in 65% of encounters, and offered a verbal apology in 47%. Surgeons acknowledged or validated patients' emotions in 55% of scenarios. Eight percent discussed how similar errors would be prevented, and 20% offered a second opinion or transfer of care to another surgeon. CONCLUSIONS: The patient safety movement calls for disclosure of medical errors, but significant gaps exist between how surgeons disclose errors and patient preferences. Programs should be developed to teach surgeons how to communicate more effectively with patients about errors.

The influence of the surgeon's and the hospital's caseload on survival and local recurrence after colorectal cancer surgery.

BACKGROUND: Past studies have identified surgeon- and institution- related characteristics as prognostic factors in colorectal cancer surgery. The present work assesses the influence of the surgeon's and the hospital's caseload on long-term results of colorectal cancer surgery. METHODS: The data on 2706 patients from 2, randomized, colorectal cancer trials (Swiss Group for Clinical Cancer Research [SAKK] 40/81, SAKK 40/87) investigating adjuvant intraportal and systemic chemotherapy and 1 concurrent registration study (SAKK 40/88) were reviewed. A first analysis included 1809 eligible, nonmetastatic patients from all 3 studies. A subsequent subgroup analysis included 915 eligible patients from both randomized trials. Overall survival (OS), disease-free survival (DFS), and local recurrence (LR) were analyzed in multivariate models taking into account the possible effect of clustering. The main potential covariates were surgeon's annual caseload (>5 operations/year vs < or =5 operations/year), hospital's annual caseload (>26 operations/year vs < or =26 operations/year), tumor site, T stage, and nodal status. RESULTS: Primary analysis of all 3 studies combined found a high surgeon's caseload to be positively associated with OS (P = .025) and marginally with DFS (P = .058). Separate analysis for each trial, however, showed that a high surgeon's caseload was beneficial for outcome in both randomized trials but not in the registration study. A subgroup analysis of 915 patients with 376 rectal and 539 colonic primaries from both randomized trials, therefore, was performed. Neither age, gender, year of operation, adjuvant chemotherapy (intraportal vs systemic vs operation alone), hospital academic status (university vs non-university), training status of the surgeon (certified surgeon vs surgeon-in-training), nor inclusion in 1 of the 2 randomized trials (SAKK 40/81 vs SAKK 40/87) was a significant predictor of outcome. However, both high surgeon's and high hospital's annual caseloads were independent, beneficial prognostic factors for OS (P = .0003, P = .044) and DFS (P = .0008, P = .020), and marginally significant factors for LR (P = .057, P = .055). CONCLUSIONS: High surgeon's and hospital's annual caseloads are strong, independent prognostic factors for extending overall and disease-free survival and reducing the rate of local recurrence in 2 randomized colorectal cancer trials.
