Should general surgeons perform specialty procedures? An outcome experience with reduction mammoplasty.

Recent health care reform proposals have emphasized the need for "generalists" over "specialists." Particularly targeted are the "surgical specialties." If much of this reform comes to pass, this may leave patients for whom the only surgical care may come from the general surgeon. In this setting, opportunities exist for the general surgeon to provide services that now are claimed by surgical specialists. This study reports the outcome experience of one general surgeon providing one such procedure, reduction mammoplasty, to a beneficiary population. Over a 26 month period, 50 reduction mammoplasties were performed. An average of 1527 grams of breast tissue were removed from each patient. There were no episodes of nipple necrosis or other complications requiring reoperation. At 1-26 months follow-up, all patients had relief of presenting symptoms, 90 per cent of patients had normal nipple sensation; all patients were satisfied with the results and would have the operation again by the same surgeon. These results show that a motivated and well-trained general surgeon can provide specialty surgical care to a potentially underserved population. General surgeons should be allowed to develop and practice the full range of skills they will need to take advantage of the opportunities that will be available to the surgical "generalist."

Information retrieval patterns and needs among practicing general surgeons: a statewide experience.

Information retrieval has progressed from a reliance on traditional print sources to the modern era of computer databases and online networks. Surgeons, many from remote areas not served by professional medical libraries, must develop and maintain skills in information retrieval and management in both electronic and standard formats. One hundred thirty-three New Mexico general surgeons were surveyed to identify their information-seeking patterns in five areas: retrieval purposes, retrieval sources, barriers to access, techniques used, and continuing education needs. Ninety-nine (74.4%) surgeons responded to the survey. Ninety-five percent utilize professional meetings, the medical literature, and physician colleagues as information sources. Only 17% utilize the outreach services of the state's only medical school library. Common retrieval barriers were practice demands (71%), isolation from medical schools (30%), computer illiteracy (28%), and rural environment (25%). Continuing education topics related to information management would be valuable to 61% of the surgeons. Sixty-nine percent believe their current ability to access biomedical information is adequate, despite most frequently accessing their personal libraries for information related to decision-making or patient management. These data suggest that, despite significant information needs, surgeons have not embraced newer forms of information retrieval. It is imperative that surgeons acquire and maintain modern information retrieval skills as a means of remaining up-to-date in their profession. Professional surgical organizations and medical librarians should collaborate on these continuing education ventures.

[Does the dosage of mitomycin-C applied during filtering surgery of glaucoma vary with the individual surgeon?].

PURPOSE: The purpose of this study was to estimate the quantity of mitomycin-C contained in sponges prepared by different surgeons as compared to that in applicators of the type used in Schirmer's test graduation (5 x 5 mm). MATERIALS AND METHODS: Four surgeons each cut and prepared 10 sponges for intraoperative use according to their usual method. The same procedure was performed with 10 Schirmer's test graduations. Each sponge and each graduation was immersed in a solution of mitomycin-C 0.2 mg/ml, and the quantity of antibiotic (microgram) in each was calculated as the difference between wet and dry weight. RESULTS: The mean quantity (+/-SEM) of mitomycin-C contained in cut sponges was 9.6 +/- 4.4 micrograms (range 1.9-17.3), and differences between surgeons were statistically significant (p < 0.0001). The mean quantity of antibiotic in Schirmer's test graduation was 1.7 +/- 0.3 micrograms (range 1.1-2.5), and the differences between surgeons were not statistically significant (p = 0.79). CONCLUSION: The quantities of mitomycin-C contained in sponges prepared for glaucoma surgery differed for a given surgeon and between surgeons. Thus, variations in the doses applied to the sclera could account for certain complications due to mitomycin-C. The use of a Schirmer's test graduation improves predictability for the quantity of mitomycin-C applied to the sclera.

Design of the femoral component for cementless hip replacement: the surgeon's perspective.

Few guidelines are currently available to the surgeon when choosing a specific femoral component for cementless total hip replacement (THR). A survey of the members of the American Association for Hip and Knee Surgeons (AAHKS) was conducted to gain insight into the importance of implant material, stress shielding, and micromotion in the selection of cementless femoral components. A comprehensive survey was distributed to 300 orthopedic surgeons selected from the members of the AAHKS; 169 of the 300 surgeons completed the detailed questionnaire. The results of the survey were analyzed using the SPSS software package to obtain general trends in opinion, and a stepwise regression analysis was used to correlate responses with training and clinical experience. Interestingly, there was little consensus among surgeons with respect to the relative importance of implant material, stress shielding, and micromotion in the selection of prostheses for cementless THR. In general, bone loss secondary to stress shielding was the least important issue, and axial and rotational micromotion were considered progressively more significant problems. Cementless titanium alloy stems were perceived as offering no significant advantage over cobalt chrome alloy stems. Moreover, there was no consensus as to whether a collar was advantageous. Prosthesis stability, restoration of motion, and a proven clinical record were more important to surgeons than were ease of implantation and removal, cost, and availability.

A survey of general surgeons' attitudes towards breast reconstruction after mastectomy.

Within the last 15-20 years there have been many changes in the management of breast cancer. Along with changes in treatment, possibilities for breast reconstruction have become increasingly sophisticated and commonplace. Despite the availability of breast reconstruction, we have noted large variations in referral patterns. Because the surgical treatment of breast cancer is largely undertaken by general surgeons, we investigated general surgeons' attitudes towards reconstruction using a postal questionnaire. In 1995, a questionnaire involving hypothetical criticisms was sent to general surgical members of the Association of Surgeons of Great Britain and Ireland. A total of 136 surgeons responded, 79 (58%) of whom had a specialist interest in breast cancer. Each surgeon saw an average of 68 new cases of breast cancer per year (range 0-400). The general surgeons were concerned about three areas: (1) 32.3% felt that breast reconstruction might adversely delay the detection of local recurrence; (2) 16.6% were worried that breast reconstruction has high morbidity; and (3) 17.4% said that patients did not want breast reconstruction despite being advised of its availability. To investigate these concern's further, an extensive literature search was undertaken. There is no evidence that breast reconstruction delays the detection of local recurrence. With appropriate patient selection, the morbidity of reconstructive options appears very acceptable. Finally, immediate breast reconstruction has psychological benefits when compared with delayed reconstruction.

Are complication rates for elective primary total hip arthroplasty in Ontario related to surgeon and hospital volumes? A preliminary investigation.

OBJECTIVE: To test the hypothesis that complication rates for elective total hip replacement operations are related to surgeon and hospital volumes. DESIGN: Retrospective population cohort study. STUDY COHORT: Patients who had undergone elective total hip replacement in Ontario during 1992 as captured in the Canadian Institute for Health Information database. MAIN OUTCOME MEASURES: In-hospital complications, 1- and 3-year revision rates, 1- and 3-year infection rates, length of hospital stay, and 3-month and 1-year death rates. RESULTS: Surgeons with patient volumes above the 80th percentile (more than 27 hip replacements annually) discharged patients approximately 2.4 days earlier (p < 0.05) than surgeons with volumes below the 40th percentile (less than 9 hip replacements annually) even after adjusting for discharge disposition, hospital volume, patient age, sex, comorbidity and diagnosis. Complication rates requiring hospital readmission and death rates did not differ by surgeon or hospital volume (p > 0.05). CONCLUSIONS: There is no evidence to support regionalization of elective hip replacement surgery in Ontario based on adverse clinical outcomes. Surgeons who perform a large number of total hip replacements are discharging patients earlier than less experienced surgeons, without any-demonstrable increase in complications leading to hospital readmission. The explanation for this observation remains unknown and will require further study.

[Physicians and surgeons during the inquisition in new Spain].

The origins of New Spain Inquisition whose jurisdiction extended also to Philippine Islands, are related herein. Physicians and surgeons who worked as Inquisition officers are discussed, from the first Dr. Juan de la Fuente who was appointed on May 9, 1572, to Dr. Pedro del Castillo, appointed on September 24, 1644. Likewise, physicians and surgeons judged by the Holy Office are mentioned. During the XVI century, those judged were few and insignificant personages, the first was the Irish Protestant William Corniels a barber surgeon, who arrived with the John Hawkins' pirate fleet in 1568 and settled in Guatemala. Some physicians and surgeons were judged as "Judaizers" during the first half of the XVII century. Many physicians and surgeons were prosecuted in Mexico, as well as in the Philippine Islands, in the second half of the XVIII century because they were Freemasons or supporters of French Revolution ideology. Among those was the unfortunate Dr. Enrique Esteban Morel, who introduced into Mexico the method of antivariolar inoculation at the time of the great epidemic out-break of 1779. It should be a gesture of justice to build a memorial in the ancient Inquisition Palace to honor this Public Health's worthy physician.

Patient, caregiver, and surgeon perceptions of quality of life following anterior skull base surgery.

OBJECTIVE: To estimate the agreement between surgeons' and lay caregivers' quality-of-life (QOL) perceptions of patients undergoing major skull base surgery. DESIGN: Cohort survey of patients who had undergone anterior skull base tumor excision. SETTING: University-affiliated medical center. PARTICIPANTS: Thirty-five patients and their lay caregivers participated in the study. MAIN OUTCOME MEASURES: A triple survey was performed: each patient and his or her caregiver were asked to answer 35 questions related to 6 distinct QOL domains: role of performance, physical function, vitality, pain, specific symptoms, and effect on emotions. The composite health-related QOL of the patients was also rated on an ordinal scale by 3 surgeons who participated in the operation and follow-up. RESULTS: An overall significant agreement was found between patients' and caregivers' scores at the group level (mean scores of each domain) and individual level (patient-caregiver pairs) (r = 0.76, P<.001). There was a minor correlation in the effect on emotions domain and no correlation in the pain domain. We found no correlation between the surgeons' and patients' ratings. The operating surgeons tended to overate their patients' QOL. CONCLUSIONS: The study results show that the surgeon's perception of his or her patient's QOL is not sufficiently accurate to correctly estimate patients' QOL status. These judgments should come from the patient or from the caregiver, whose perception can be used in clinical trials as a proxy for estimation of a patient's QOL.

Objective evaluation of a laparoscopic surgical skill program for residents and senior surgeons.

BACKGROUND: Laparoscopic surgery adapts poorly to apprenticeship models for general surgical training. Standardized skill acquisition and validation programs, targeted performance goals, and a supervised, enforced, skill-based curriculum that readily can be shared between trainee and instructor must replace the observation and incremental skill-acquisition model used in an open surgical environment. The Yale Laparoscopic Skills and Suturing Program was used to develop a data bank for objective evaluation of dexterity and suturing skills for laparoscopic surgical training. The current study compares trainee and senior surgeon performance in this standardized training program. OBJECTIVE: To compare objectively evaluated laparoscopic surgical skills and suturing capability of senior surgeons and of residents after they have completed the same standardized training regimen. METHODS: Two hundred ninety-one trained surgeons performed 8730 standardized laparoscopic dexterity drills and 2910 intracorporeal suturing exercises in the Yale Laparoscopic Skills and Suturing Program. Their performance was supervised by an instructor who recorded performance and timing of the tasks in a 2 1/2-day program. Ninety-nine residents performed the same drills and exercises the same number of times and followed the same technique for intracorporeal suturing. Percentile graphs were prepared for each type of drill and suturing exercise to allow comparison of levels of achievement among different training groups. RESULTS: The performance of the residents was the same as that of trained surgeons for the rope pass drill and the suturing exercise. Residents in comparison with trained surgeons performed the triangle transfer drill faster and the new cup drop drill and old cup drop drill more slowly. There was no significant difference in performance between male and female residents. CONCLUSION: Basic skills relevant to laparoscopic performance can be acquired with a high level of competence in a brief course unrelated to prior surgical experience, sex, or age.

Maintaining trust in the surgeon-patient relationship: challenges for the new millennium.

Changes in the structure of the health care system have placed unprecedented stress on the surgeon-patient relationship. The essential trust placed in the surgeon by her patients has been weakened by changes in the structure and financing of the health care system. This article considers the historical and ethical foundation of the surgeon-patient relationship and proposes that the primary moral obligation of surgeons is to strengthen and earn patient trust. By improving communication skills, enhancing ethical education, serving as consistent advocates for patients, and conducting patient-focused outcome research, the surgical community can meet its moral obligation by increasing trust in the surgeon-patient relationship.

Surgeon and hospital leadership during terrorist-related multiple-casualty events: a coup d'état.

HYPOTHESIS: During terrorist-related multiple-casualty events (TMCEs), the role of the surgeon expands beyond providing traditional trauma care. DESIGN: Survey and expert opinion poll. SETTING: Interviews (structured, open/closed questions) conducted in 14 Israeli hospitals. PARTICIPANTS: Sixty hospital physicians selected for their experience in TMCEs. MAIN OUTCOME MEASURES: Identification of key staff members and their roles during TMCEs and development of recommendations for hospital management. RESULTS: During TMCEs, hospitals are comanaged by a physician hospital administrator and a clinical medical director (usually a surgeon) responsible for prioritization of patient care. Primary triage is often performed by a general surgeon experienced in trauma. Trauma specialists supervise other physicians providing patient care. Key staff members to recruit to the hospital at event onset include the chiefs of surgery and anesthesiology, attending surgeons and anesthesiologists, critical care physicians, and radiologists. Paramedics stationed in-hospital as emergency medical services liaisons improve communication between the field and the hospital. Operating room and intensive care unit (ICU) management remain unchanged. Controversies exist regarding continuation of planned and ongoing elective surgery and ICU triage despite use of the postanesthesia care unit as an extension of the ICU. CONCLUSIONS: During TMCEs, surgeons fill pivotal roles in hospital command and control and hands-on clinical care. Anesthesiology services and ICUs are relied on heavily for provision of patient care and should be included in information flow and decision making. Operating room and ICU management should remain unchanged since the care of patients who are already in these locations at the time disaster strikes is a subject of controversy with ethical implications.

Surgeon and hospital characteristics as predictors of major adverse outcomes following colon cancer surgery: understanding the volume-outcome relationship.

HYPOTHESIS: Although numerous studies have demonstrated an association between surgical volume and improved outcome in cancer surgery, the specific structures and mechanisms of care that are associated with volume and lead to improved outcomes remain poorly defined. We hypothesize that there are modifiable surgeon and hospital characteristics that explain observed volume-outcome relationships. DESIGN: Retrospective cohort study. SETTING: Surveillance, Epidemiology, and End Results cancer registry areas. PATIENTS: Patients aged 66 years and older, diagnosed and surgically treated for stage I, II, or III colon cancer between 1992 and 1996 (n = 22 672). MAIN OUTCOME MEASURES: Thirty-day postoperative mortality and 30-day postoperative procedural interventions, including reoperation and image-guided percutaneous procedures. RESULTS: Surgeon volume, but not hospital volume, is a significant predictor of postoperative procedural intervention (adjusted odds ratio for very high-volume surgeons vs low-volume surgeons, 0.79; 95% confidence interval, 0.64-0.98). In the unadjusted analyses, high hospital volume (odds ratio, 0.67; 95% confidence interval, 0.56-0.81) and very high hospital volume (odds ratio, 0.65; 95% confidence interval, 0.54-0.79) is associated with lower postoperative mortality. Postoperative procedural intervention is not a significant mediator of the relationship between hospital volume and mortality. A single variable-the presence of sophisticated clinical services-was the most important explanatory variable underlying the relationship between hospital volume and mortality. CONCLUSIONS: Very high surgeon volume is associated with a reduction in surgical complications. However, the association between increasing hospital volume and postoperative mortality appears to derive mainly from a full spectrum of clinical services that may facilitate the prompt recognition and treatment of complications.

Frequency of puncture injuries in surgeons and estimated risk of HIV infection.

To evaluate the occupational risk of human immunodeficiency virus (HIV) infection, we surveyed 202 surgeons working in the New York City metropolitan area. One hundred seventy-three (86%) surgeons reported at least one puncture injury in the preceding year (median number, 2 per year; interquartile range, 1 to 4 per year). Seventy-six percent of the injuries occurred during surgery, and the median injury rate was 4.2 per 1000 operating room hours. Twenty-five percent of the surgeons sustained yearly injury rates of 9 or more per 1000 operating room hours, and these high rates were independent of sex, age, type of practice, operative work load, or hospital location. Fifty-three percent of all injuries involved the index finger of the nondominant hand. If the prevalence of HIV infection in surgical patients is 5%, then the estimated 30-year risk of HIV seroconversion is less than 1% for 50% of the group, 1% to 2% for 25% of the group, 2% to 6% for 15% of the surgeons, and greater than 6% for 10% of the surgeons.

Exploring molecular biology. An older surgeon looks at a new universe.

The rapidity and the magnitude of progress in molecular biology slipped by many of us practicing surgeons. Although articles about molecular medicine appear regularly in our surgical literature, for many of us, their content is rather mysterious. The articles often end with a glossary, because most readers do not understand the language. In November 1993, the entire issue of the Archives of Surgery was devoted to molecular medicine. In an editorial, Claude Organ, Jr, MD, a member of this association, encouraged the surgeon to "cohabit" with the molecular scientist. Many university departments of surgery have professors who are both surgeons and molecular biologists. Ed Passaro, MD, also a member of this association, observed in 1992 that most surgeons had overlooked this new field and needed to learn about it to play a role in applying it to clinical medicine. That means knowing what new tests and treatments are available and how to apply them. It means being able to counsel patients. Also, it is important for knowledgeable surgeons to serve on the regular hospital committees that will oversee these new tests and treatments, and to offer their unique judgment in assessing risk, reward, and ethical implications.

Physician-patient communication. The relationship with malpractice claims among primary care physicians and surgeons.

OBJECTIVE: To identify specific communication behaviors associated with malpractice history in primary care physicians and surgeons. DESIGN: Comparison of communication behaviors of "claims" vs "no-claims" physicians using audiotapes of 10 routine office visits per physician. SETTINGS: One hundred twenty-four physician offices in Oregon and Colorado. PARTICIPANTS: Fifty-nine primary care physicians (general internists and family practitioners) and 65 general and orthopedic surgeons and their patients. Physicians were classified into no-claims or claims (> or =2 lifetime claims) groups based on insurance company records and were stratified by years in practice and specialty. MAIN OUTCOME MEASURES: Audiotape analysis using the Roter Interaction Analysis System. RESULTS: Significant differences in communication behaviors of no-claims and claims physicians were identified in primary care physicians but not in surgeons. Compared with claims primary care physicians, no-claims primary care physicians used more statements of orientation (educating patients about what to expect and the flow of a visit), laughed and used humor more, and tended to use more facilitation (soliciting patients' opinions, checking understanding, and encouraging patients to talk). No-claims primary care physicians spent longer in routine visits than claims primary care physicians (mean, 18.3 vs 15.0 minutes), and the length of the visit had an independent effect in predicting claims status. The multivariable model for primary care improved the prediction of claims status by 57% above chance (90% confidence interval, 33%-73%). Multivariable models did not significantly improve prediction of claims status for surgeons. CONCLUSIONS: Routine physician-patient communication differs in primary care physicians with vs without prior malpractice claims. In contrast, the study did not find communication behaviors to distinguish between claims vs no-claims surgeons. The study identifies specific and teachable communication behaviors associated with fewer malpractice claims for primary care physicians. Physicians can use these findings as they seek to improve communication and decrease malpractice risk. Malpractice insurers can use this information to guide malpractice risk prevention and education for primary care physicians but should not assume that it is appropriate to teach similar behaviors to other specialty groups.

Attitudes of cardiothoracic surgeons in the UK to human immunodeficiency virus.

A survey was carried out into attitudes of cardiothoracic surgeons in the UK to human immunodeficiency virus type 1 (HIV-1) infection associated with clinical situations that would normally have been managed surgically with low operative mortality rates and long median survival times. The survey response rate was 72.4 per cent. In patients with acute valvular insufficiency or with continuing angina despite maximal medical therapy (unstable angina) who were HIV-1 antibody positive, 75.8 and 80.8 per cent, respectively, of surgeons would operate. If the patient had end-stage infection, acquired immune deficiency syndrome (AIDS), 29.7 per cent and 34.7 per cent, respectively, would consider surgical intervention. When asked to perform simple procedures such as open lung biopsy or pleurectomy on a patient with AIDS, more than half of surgeons would operate (52.2 and 65.6 per cent respectively). In patients with operable carcinoma of the lung and asymptomatic HIV-1 infection 52.3 per cent would operate. This fell to 15.0 per cent if the patient had a diagnosis of AIDS. The majority of surgeons (77.2 per cent) felt patients should have an HIV-1 antibody test before operation and this rose to 95.6 per cent if patients were in a high-risk group; 60.2 per cent of surgeons had changed their surgical practice to reduce the risks of blood-borne infection.

How surgeon age affects surveillance strategies for extremity soft tissue sarcoma patients after potentially curative treatment.

BACKGROUND: The optimal strategy for follow-up of extremity soft tissue sarcoma patients after potentially curative treatment remains unknown. We investigated whether the date of completion of formal surgical training affects choice of surveillance strategy. MATERIALS AND METHODS: The 1,592 members of the Society of Surgical Oncology were asked how often they use 12 separate surveillance modalities during years 1-5 and 10 postsurgery. The motivation underlying follow-up was assessed separately. Repeated-measures analysis of variance was used to compare practice patterns by the year in which the surgeon's formal surgery training was completed, controlling for tumor grade, tumor size, and year postsurgery. RESULTS: Of the 716 respondents, 318 performed surgery and also provided long-term postoperative surveillance for their patients. These respondents were considered evaluable. Erythrocyte sedimentation rate, extremity X ray, and bone scan were the follow-up tests which differed significantly among physician age groups. Surgeons who completed training more than 30 years ago ordered erythrocyte sedimentation rate more frequently (P < 0.001). Surgeons in the 21-30 year category ordered extremity X ray and bone scan more frequently (P < 0.05), but the absolute differences among age groups were quite small. Older surgeons were also significantly more likely to believe that follow-up is clinically worthwhile. CONCLUSIONS: The posttreatment surveillance practice patterns of the members of the Society of Surgical Oncology caring for extremity soft tissue sarcoma patients vary only marginally with the length of time since completion of training. Postgraduate education may be one factor homogenizing surgeon behavior in this important aspect of cancer patient care.

Current follow-up strategies after resection of colon cancer. Results of a survey of members of the American Society of Colon and Rectal Surgeons.

UNLABELLED: The follow-up of patients after potentially curative resection of colon cancer has important clinical and financial implications for patients and society, yet the ideal surveillance strategy is unknown. PURPOSE: The aim of this study was to determine the current follow-up practice pattern of a large, diverse group of experts. METHODS: The 1,663 members of The American Society of Colon and Rectal Surgeons were asked, via a detailed questionnaire, how often they request nine discrete follow-up evaluations in their patients treated for cure with TNM Stage I, II, or III colon cancer over the first five posttreatment years. These evaluations were clinic visit, complete blood count, liver function tests, serum carcinoembryonic antigen (CEA) level, chest x-ray, bone scan, computerized tomographic scan, colonoscopy, and sigmoidoscopy. RESULTS: Forty-six percent (757/1663) completed the survey and 39 percent (646/1663) provided evaluable data. The results indicate that members of The American Society of Colon and Rectal Surgeons generally conduct follow-up on their patients personally after performing colon cancer surgery (rather than sending them back to their referral source). Routine clinic visits and CEA levels are the most frequently performed items for each of the five years. The large majority (> 75 percent) of surgeons see their patients every 3 to 6 months for years 1 and 2, then every 6 to 12 months for years 3, 4, and 5. Approximately 80 percent of respondents obtain CEA levels every 3 to 6 months for years 1, 2, and 3, and every 6 to 12 months for years 4 and 5. Colonoscopy is performed annually by 46 to 70 percent of respondents, depending on year. A chest x-ray is obtained yearly by 46 to 56 percent, depending on year. The majority of the members of The American Society of Colon and Rectal Surgeons do not routinely request computerized tomographic scan or bone scan at any time. There is great variation in the pattern of use of complete blood count and liver function tests. Members of The American Society of Colon and Rectal Surgeons from the United States tend to follow their patients more closely than do those living in other countries. The intensity of follow-up does not markedly vary across TNM Stages I to III. CONCLUSION: The surveillance strategies reported here rely most heavily on clinic visits and CEA level determinations, generally reflecting guidelines previously proposed in the current literature.
