The oral examination: awesome or awful?

Medical and surgical specialty boards are constantly striving to insure that those seeking certification in their specialty are adequately trained and sufficiently evaluated to guarantee the highest quality of patient care. One traditional component of the evaluation process, the oral examination, has been discontinued by some specialty boards but is still retained by most. A review of the history of the oral examination, combined with personal experiences of the author, suggests that this particular rite of passage may have outlived its usefulness in all but a few areas of medical specialization. Addressing the most pressing problems of patient mismanagement in the most visible area of practice, the hospital environment, requires that major emphasis be on the improvement of hospital practices rather than on doctors' qualifications. Only in this way can we ensure patient safety and restore patients' confidence in the care they receive and in the doctors responsible for administering it.     

Postgraduate clinical education — the Canadian experience

To obtain a quantitative measure of the extent to which graduate education and qualification for specialty practice have become an integral part of the total educational experience, samples of the graduating classes of 1960, 1964, 1968 and 1970 of Canadian medical schools were tracked through postgraduate educational training and into specialty certification. From the 1960 cohort 65% chose a career recognized by special certifying exams in Canada and/or the United States, entered a residency, completed it and achieved certification of special competence. From the 1970 cohort, by the end of 1972 approximately 50% had entered a recognized specialty training program leading to certification. The diminishing trend toward specialty practice is demonstrated by reviewing the comparative figures in the 1964 and 1968 cohorts. Evidence garnered in this study indicates a continuing strong motivation for specialty practice although family medicine and/or general practice appear increasingly attractive as career choices. Strong provincial educational forces as well as social and other forces will probably continue to modify career selection and may lead an increasing number of Canadian medical graduates into family practice.     

Certification of specialists: survey of candidates and review of the literature.

To evaluate the specialty certification process, the Canadian Association of Internes and Residents (CAIR) surveyed 634 candidates who had attempted the written and oral exams of the Royal College of Physicians and Surgeons of Canada. The results suggest that in-training evaluation is a more reliable and valid assessment of competence than the written and oral exams. There is a lack of well defined program objectives that are coordinated with the examinations. CAIR recommends that the present concept of an examination "hurdle" be replaced by different, integrated methods of assessment during training, and that an effective appeal mechanism be developed.     

Organisation of vascular surgical services: evolution or revolution?

The trend towards subspecialisation in hospital services is likely to lead to the development of vascular surgery as a separate specialty. If vascular surgery is to emerge as a high quality service then vascular emergencies--a substantial component of the workload--should be dealt with by surgeons with adequate training, and all patients should have equal access to the service. A specialist vascular surgical unit would have to be large enough to make efficient use of other services that it needs, such as radiology, and so may require the amalgamation of smaller health district units. Because of the differing local degrees of subspecialisation, national or regional strategies for vascular surgery must be developed.     

Current Trainee and Workforce Patterns for Thyroid and Parathyroid Surgery in the United States

ObjectiveThyroid and parathyroid surgery is performed by both general surgeons and otolaryngologists. We describe the proportion of surgeries performed by specialty, providing data to support decisions about when and to whom to direct research, education, and quality improvement interventions.MethodsWe tabulated case numbers for privately insured patients undergoing thyroid and parathyroid surgery in Marketscan: 2010–2016 and trainee case logs for residents and fellows in general surgery and otolaryngology. Summary statistics and tests for trends and differences were calculated.ResultsMarketscan data captured 114 500 thyroid surgeries. The proportion performed by each specialty was not significantly different. Otolaryngologists performed 58 098 and general surgeons performed 56 402. Otolaryngologists more commonly performed hemithyroidectomy (n = 25 148, 43.29% of all thyroid surgeries performed by otolaryngologists) compared to general surgeons (n = 20 353, 36.09% of all thyroid surgeries performed by general surgeons). Marketscan data captured 21 062 parathyroid surgeries: 6582 (31.25%) were performed by otolaryngologists, and 14 480 (68.75%) were performed by general surgeons. The case numbers of otolaryngology and general surgery trainees completing residency and fellowship varied 6- to 9-fold across different sites. The wide variation may reflect both the level of exposure a particular training program offers and trainee level of interest.ConclusionThyroid surgical care is equally provided by general surgeons and otolaryngologists. Both specialties contribute significantly to parathyroid surgical care. Both specialties should provide input into and be targets of research, quality, and education interventions.     

Denny-Brown, Boston City Hospital, and the history of American neurology

Harvard University's Neurological Unit at Boston City Hospital (BCH) became the premier center for neurological training in the United States during the middle part of the 20th century. During part of this period (1939-1967), it was directed by Derek Denny-Brown, who had been recruited from England by Harvard president James Conant. The training program that Denny-Brown initiated at BCH emphasized neurology as a medical specialty, independent of psychiatry and neurosurgery. This program, which reflected Denny-Brown's British training, was remarkably effective and served as a model for rest of the country.     

A Retraining Program for Inactive Physicians

During the past two years a pilot project was conducted in which 19 inactive physicians were retrained in preparation for resumption of active practice. The initial program consisted of a flexible training program of six months to one year patterned after conventional internship-residency concepts. During the second year the program was modified by providing an initial condensed indoctrination period of two months'' duration especially designed for this purpose, followed by a preceptorship type of training.The project was considered successful in permitting trainees to enter some form of active medical work, or to enroll in formal specialty training. The observations made by the faculty of the program and its accomplishments are discussed in the light of the effort expended and the cost of the project.     

The specialty of colon and rectal surgery: its impact on patient care and role in academic medicine

The specialty of colon and rectal surgery, a specialty of general surgery, has evolved from the field of proctology. Clinical care has demonstrated decreased number of patients requiring intestinal stomas, improved quality of life in patients with benign anorectal disorders, and more favorable results in patients afflicted with primary and recurrent colorectal cancer. Basic science investigations have spawned from clinical questions such as the molecular biology of colorectal cancer, use of cyclooxygenase inhibitors and polyp regression, and novel cytokine antagonists in inflammatory bowel disease. Medical students are exposed to surgeons with expertise in anorectal anatomy and physiology, mechanisms of carcinogenesis and the importance of screening for detection of colorectal cancer, and novel therapies for inflammatory bowel disease. Surgical residents benefit by having a colorectal surgeon on the faculty by repetitive exposure to anorectal surgery, low pelvic anastomoses, stoma creation and closure, and surgery involving the small intestine. Senior colorectal surgeons will develop critical pathways for the healthcare delivery of patients afflicted with colorectal disease. The specialty of colorectal surgery will continue to translate into improved patient care and positively impact in academic medicine by providing expertise into student and resident training and generate highly sophisticated clinical and basic science investigations.     

The specialty match: a necessity in the equitable resident selection process.

For many years directors of Canadian postgraduate specialty programs have selected candidates in an uncontrolled and haphazard way. Candidates and programs alike have therefore been unfairly treated. Since 1986 the Canadian Intern and Resident Matching Service has offered a centrally coordinated matching program to allow candidates to select specialty programs at centres of their choice and program directors to rate candidates. The result has been an effective method to achieve fairness in the selection of postgraduate trainees for participating Canadian specialty programs.     

A new educational role for plastic surgery in the fourth year of medical school

At most medical schools, students are offered limited or sporadic experiences in plastic surgery. This is unfortunate because all physicians need to possess the knowledge and skills to evaluate skin lesions and participate in wound management. Also, students who are considering a career in plastic surgery do not have adequate information to make informed decisions. With the restructuring of plastic surgery training programs, career decisions of individuals interested in plastic surgery are being made earlier than ever before in the education continuum, and the aforementioned problem assumes greater magnitude both for the students and the faculty. At MCP-Hahnemann School of Medicine, basic plastic surgery experiences have been integrated into the third-year surgery clerkship as a requirement for all students, and a Plastic Surgery Pathway has been designed in conjunction with the school's pathway system for fourth-year students. The Pathway provides a framework for the student to select a combination of rotations that will best provide an appropriate broad-based education in preparation for training in plastic surgery, and it provides extensive guidance by faculty members in the discipline to assist with career decisions, rotation selection, and preparations for the residency application process. Students in the Plastic Surgery Pathway are required to take rotations in medicine, neurology, and plastic surgery. The remaining rotations are selected from a list of options based on the student's individual learning needs, interests, and career aspirations. Early experience with the Plastic Surgery Pathway has shown that it has been well received by students and faculty, has assisted students with their career decisions, and has led to an increased student awareness of the importance and relevance of the specialty.     

Variation in prices charged to patients for specialty intraocular lenses inserted during universally covered cataract surgery

Background

Patients often pay for specialty intraocular lenses (IOLs) for cataract surgery covered by universal insurance. This practice creates the potential for inequitable pricing where the medical service provider is also the retailer. We measured the variation in prices between cataract surgeons for the same IOL and associated testing.

Methods

We telephoned every cataract surgeon in Ontario, Canada, and asked their price for the most common type of specialty IOL as a prospective patient. We measured the total prices quoted and variation between providers.

Results

We contacted 404 ophthalmologists. There were 256 that performed cataract surgery but 127 offered the most commonly employed specialty IOL and would provide a price to patients over the telephone. We obtained prices from all 127 ophthalmologists. Prices for the same lens and associated testing varied substantially between ophthalmologists from $358 to $2790 (median $615, interquartile range $528–$915). There was variation in all components of the total out-of-pocket price, including the price for the IOL itself, charges for uninsured eye measurements, and non-specific supplemental fees.

Conclusion

Although cataract surgery is covered by public health insurance, some ophthalmologists charge much more than others for the same specialty IOL and associated testing. Greater access to price information and better regulatory control could help ensure patients receive fair value for out-of-pocket health expenses.     

The Effect of Animal-Assisted Therapy on Pain Medication Use After Joint Replacement

Animal-assisted therapy (AAT) has been used in a variety of healthcare settings and studies to evaluate the potential patient benefits are warranted. This retrospective study measured the impact of AAT on the use of oral pain medications by adults after total joint replacement surgery. One group of patients received care in a hospital with an AAT program and the comparison group was in a hospital without an AAT program. Adult patient cohorts were matched on: age, gender, ethnicity, length of stay, and Diagnosis Related Group code for type of total joint replacement. Pain medication doses, converted into morphine equivalent daily doses (MEDD), were compared. Pain medication use was significantly less in the AAT group: 15.32 mg vs. 21.16 (t₍₁₁₉₎ = 2.72, p = 0.007). The effectiveness of AAT in decreasing the need for pain medication and its effect on patient well-being in the post-operative period and in other settings deserves further study.     

The effect of increased plastic surgeon supply on fees for aesthetic surgery: an economic analysis

The size of the plastic surgery workforce has important effects on the financial environment of the specialty. Economic theory predicts that increasing the area supply of surgeons performing aesthetic surgery will result in lower fees for their services. This study tested that theory in the actual aesthetic surgery marketplace. The study examined the ratio of plastic surgeons to the general population of several states. It then traced the aesthetic surgery fees resulting from different densities of area plastic surgeons. This information was economically analyzed to project the fee effects of possible future changes in the number of practicing plastic surgeons. For the states of New York, California, and Texas, there is a proportional decrease in fees as the density of plastic surgeons increases. For example, New York has 34 percent more plastic surgeons proportionally than Texas, and its fees are 30 percent lower in real dollars. Economic analysis can project the fee effects of changing the supply of surgeons performing aesthetic surgery. The analysis reveals that a 30 percent national increase in the supply of plastic surgeons would lower fees by approximately 32 percent. Similarly, if the number of plastic surgeons increases by 50 percent, fees will decrease by approximately 53 percent. However, these fee effects can be mitigated by expanding the demand for aesthetic surgery. In conclusion, the size of the plastic surgery workforce has profound effects on the fees paid for aesthetic surgery, and the magnitude of these effects can be understood, predicted, and optimized using the tools of economics.

A calculator program for least-squares parameter estimation according to the one-compartment kinetic model with zero-order input

A calculator program that performs a nonlinear least-squares fit to data conforming to the one-compartment model with zero-order input is described. The program, which is designed for the Hewlett-Packard HP-41 CV calculator, is based on the Gauss-Newton iterative algorithm as modified by Hartley. A subroutine for calculation of initial parameter estimates is incorporated into the program. Plasma concentration data relative to a single oral dose of a sustained-release theophylline formulation are used to demonstrate the practical application of the program.     

Evaluation of the careers of graduates of the University of Manitoba's BSc (Medicine) program.

The careers of graduates who had taken the BSc (Medicine) (BScMed) program at the University of Manitoba, Winnipeg, between 1950 and 1975 were compared with those of matched classmate controls to determine whether the program had any influence on the research careers of the graduates. More BScMed graduates than control subjects chose an academic career (49% v. 21%), achieved specialty certification (83% v. 65%), and obtained grants (51% v. 18%) and personal awards (37% v. 18%). The BScMed graduates also had significantly more publications than the control subjects. Although part of the difference between the two groups may be explained by the tendency of students who were more inclined toward an academic career to enter the BScMed program, it was evident that the program has a substantial effect on promoting the development of clinical investigators.     

Measuring readmission rates.

OBJECTIVE--To assess the feasibility of extracting data on readmissions and readmission rates from Körner data for use as health service indicators. DESIGN--Retrospective analysis of inpatient Körner data for January 1988 to April 1989. SETTING--Three districts in North East Thames region. MAIN OUTCOME MEASURES--Number of readmissions after index discharge for all acute specialties combined and by specialty (general medicine, general surgery, gynaecology, trauma and orthopaedics, and geriatrics); readmission rates at 28 days after index discharge; and rates standardised for age group and sex by specialty and by consultant. RESULTS--All specialties showed an early peak in number of admissions, which levelled off by 28 days. Readmission rates at 28 days were appreciably lower in surgical specialties than in medical specialties (for example, general surgery 4.1% v geriatric medicine 15.1%). They were related to age and sex of the patient. Rates standardised for these variables did not significantly differ by district. Likewise, significant differences in standardised rates were not obtained for consultants within a specialty in one district. CONCLUSIONS--Readmission rates may be measured with Körner data. The pattern of readmissions with time means that readmission rates should be measured at not more than 28 days after the index discharge; the rates require standardisation for age and sex. Annual comparisons of standardised rates may be made among districts for combinations of specialties; those among individual consultants or specialties are unlikely to be statistically valid.     

Evaluation of cosmetic results of a randomized trial comparing surgery and radiotherapy in the treatment of basal cell carcinoma of the face

Basal cell carcinoma is the most frequent cutaneous carcinoma, and it is characterized by its local spreading and an exceptional tendency to metastasize. Radical excision or destruction ensures the highest chance of cure. The most frequent site of this tumor is the face, where radical excision is limited by the proximity of essential anatomic structures. The main difficulty is to avoid mutilation and to provide good cosmetic results despite the vicinity of the eyes, the nose, and the mouth. Surgery and radiotherapy are known to provide similar chances of cure, but results concerning cosmetic sequelae are controversial, depending sometimes on the specialty of the physician in charge of the treatment. A randomized trial was performed at the Gustave-Roussy Institute to compare basal cell carcinomas of the face treated either by surgery or by radiotherapy. In summary, a significant advantage was observed in favor of surgery, as has been published elsewhere. Looking at the details of the cosmetic results, we analyzed the specific methodology of the cosmetic evaluation set up to eradicate the usual bias owing to subjective judgments. We looked also to the evolution of the cosmetic results with time. A panel of five judges performed repeated evaluations during the follow-up, and standardized photographs were taken at each visit and rated later by three nonmedical judges. In total, 174 patients were treated by surgery and 173 by radiotherapy; the choice of the treatment was allocated by randomization. Postoperative complications were higher in the radiotherapy group. The final cosmetic results after 4 years of follow-up were rated significantly better with surgery than with radiotherapy (good in 87 percent versus 69 percent according to the patient, 79 percent versus 40 percent according to the dermatologist, and respectively for each of the observers). Evolution of the ratings during the follow-up demonstrated an improvement of the cosmesis after surgery and stable or deteriorated results after radiotherapy. The same trend was observed regardless of the site of the tumor on the face, except for the nose, where the difference--still in favor of the surgery--was not significant. Concordance of all assessments in our study was the main guarantee of reliability of our methodology for cosmetic evaluation.
