Education for educating surgeons

A systematic review of the relationship between patient mix and learning in work-based clinical settings. A BEME systematic review: BEME Guide No. 24

BACKGROUND

Clinical workplace-based learning has been the means to becoming a medical professional for many years. The importance of an adequate patient mix, as defined by the number of patients and the types of medical problems, for an optimal learning process is based on educational theory and recognised by national and international accreditation standards. The relationship between patient mix and learning in work-based curricula as yet remains unclear.

AIM

To review research addressing the relationship between patient mix and learning in work-based clinical settings.

METHOD

The search was conducted across Medline, Embase, Web of Science, ERIC and the Cochrane Library from the start date of the database to July 2011. Original quantitative studies on the relationship between patient mix and learning for learners at any level of the formal medical training/career were included. Methodological quality was assessed and two reviewers using pre-specified forms extracted results.

RESULTS

A total of 10,420 studies were screened on title and abstract. Of these, 298 articles were included for full-text analysis, which resulted in the inclusion of 22 papers. The quality of the included studies, scored with the Medical Education Research Study Quality Instrument (MERSQI), ranged from 8.0 to 14.5 (of 18 points). A positive relationship was found between patient mix and self-reported outcomes evaluating the progress in competence as experienced by the trainee, such as self-confidence and comfort level. Patient mix was also found to correlate positively with self-reported outcomes evaluating the quality of the learning period, such as self-reported learning benefit, experienced effectiveness of the rotation, or the instructional quality. Variables, such as supervision and learning style, might mediate this relationship. A relationship between patient mix and formal assessment has never been demonstrated.

CONCLUSION

Patient mix is positively related to self-reported learning outcome, most evidently the experienced quality of the learning programme.

Surgical resident satisfaction with the current surgical training program in the Riyadh area

BACKGROUND

The satisfaction of surgical residents with their training programs plays an important role in dictating its output. This survey was conducted to explore the satisfaction of surgical residents with their training programs in the Riyadh area.

METHODS

A survey questionnaire was distributed in four major hospitals to explore the view of surgical residents regarding their training programs. Frequency tables were generated for each question in the survey.

RESULTS

About 78 survey forms were distributed and 52 were retrieved (67%). About 45% of residents had a comprehensive orientation on admission to the program, but only 20% felt it was helpful. Only 40% of residents felt that their trainers were committed to training and that the consultants who were trained abroad were more committed than those trained locally (62% vs 36%, P =.01). Only 15% felt the residents themselves had enough bedside teaching or operative experience. Seventy-eight percent of the residents felt that current training does not meet their expectations. However, 85% felt that training abroad was better than local training, and 60% felt it should be mandatory. While 90% felt that training programs should be unified nationally and controlled by one organization, only 6% felt that the current governing body was capable of monitoring the training. Moreover, only 28% felt that current reviews of programs by the governing body are effective.

CONCLUSIONS

These results show that surgical residents are generally dissatisfied with current training programs. The study suggests that there are significant weaknesses in the current programs and the governing body may be ineffective in monitoring the programs. We feel that a national review of surgical training programs is warranted in view of these results.

The reliability of multiple objective measures of surgery and the role of human performance

BACKGROUND

There is a need for reliable and valid objective methods of technical skills in surgery. Six-bench surgical top stations have been combined to assess basic surgical trainees (BSTs) objectively. The current study examines its reliability and validity across repeat sittings.

METHODS

Eleven surgical trainees (6 senior BSTs and 5 higher surgical trainees [HSTs]) undertook 5 sittings of the 6-station assessment designed to be completed within 90 minutes. The 6 stations consisted of knot tying, suturing, closure of enterotomy, excision of sebaceous cyst, laparoscopic task, and instrument examination. Methods of analysis employed were motion analysis, observation with criteria, and inbuilt simulation metrics.

RESULTS

On analysis 3 knot tying and suturing stations exhibited significant differences in either time or movement; any difference was over by the second run. The intertest reliabilities were .66, .74, .55, .51, and .65 for the 5 runs. The intratest reliability across repeated sittings varied from .56 to .96. The inter-rater reliability for video assessment varied from .77 to .94.

CONCLUSION

The assessment is reliable and valid across repeated sittings. Its use in assessment of basic technical skills needs to be encouraged.

Attitudes towards skills examinations for basic surgical trainees

Objective measures of surgical skill and cognition are becoming available. A questionnaire study examining surgeons' beliefs towards a skills-based examination, current standards and possible benefits was devised. Three hundred pairs of standardised anonymous questionnaires were sent to consultants and their basic surgical trainees (BSTs) irrespective of surgical specialty. Responses were requested using a Likert scale (1-5, 3=neutral response). Two-hundred and two replies were received (including 54 pairs). BST experience ranged from 6 to 60 months (mean 24 months). When questioned regarding current training in basic surgical skills, only 34% believed that they were given adequate training at present. Sixty-four per cent of respondents believed the introduction of a skills examination would raise standards and 66% believed it necessary. Eighty-three per cent of respondents believed that they or their BST would practice these skills, if an examination were introduced and 85% wanted or would provide dedicated teaching time for this. However, 68% had no access to a dedicated skills facility, and uptake of these, where available, was variable. When questioned about their ability to perform the six appropriate tasks, there was a poor correlation of scoring between the groups. Consultants and their BSTs do not believe that they are given adequate training in basic skills. The introduction of an examination would lead to practice of these skills and is seen as a positive move.

Effect of surgical training on outcome and hospital costs in coronary surgery

BACKGROUND

There is a perceived conflict between the need for service provision and surgical training within the National Health Service (NHS). Trainee surgeons tend to be slower (thereby reducing theatre throughput), and may have more complications (increasing hospital stay and costs).

OBJECTIVE

To quantify the effect of training on outcome and costs.

DESIGN

Data on 2740 consecutive isolated coronary artery bypass (CABG) operations were analysed retrospectively. Redo and emergency procedures were excluded. The seniority of the operating surgeon was related to operating times, risk stratified outcome, and overall hospital costs.

SETTING

Regional cardiothoracic surgery unit.

MAIN OUTCOME MEASURES

Postoperative mortality; hospital costs.

RESULTS

Consultants, senior trainees, intermediate trainees, and junior trainees performed 1524, 759, 434, and 23 procedures, respectively. Trainees at the three different levels were directly supervised by a consultant in 55%, 95%, and 100% of cases. The unadjusted mortalities were 3.2%, 2.0%, 2.3%, and 4.3%, respectively (NS). There were no significant differences between the groups with respect to time in the intensive care unit and length of hospital stay. The mean cost per patient was pound6619, pound6572, pound6494, and pound6404 (NS).

CONCLUSIONS

Trainees performed 44.4% of all CABG operations. There was no detrimental effect on patient outcome, length of hospital stay, or overall hospital costs. There need be little conflict between service and training needs, even in hospitals with extensive training programmes.

Outcome in patients with colorectal cancer managed by surgical trainees

BACKGROUND

The surgeon is an important variable that influences outcome following colorectal cancer surgery. Operative training of suitable quality and quantity is essential if intersurgeon variation is to be reduced. The aim of this study was to examine the outcome of colorectal cancer surgery when a high proportion of the operations were performed by trainee surgeons.

METHODS

A prospective 7-year (1989-1996) audit of 306 consecutive colorectal cancers referred to a single general surgeon with a colorectal interest was carried out. The outcome (anastomotic leakage, 30-day mortality rate, local recurrence and cancer-related survival) of operations performed by the consultant was compared with that of his trainees.

RESULTS

Some 245 (92.5 per cent) of 265 patients undergoing laparotomy had a resection. Seventy (28.6 per cent) and 67 (27.3 per cent) of operations were performed by supervised and independent trainees respectively. There was no difference between the consultant, supervised and independent trainees for 30-day mortality rate (6.5, 6 and 4 per cent respectively), clinical anastomotic leakage rate (9, 2 and 5 per cent) and local recurrence rate (2, 3 and 7 per cent). There was no difference between the three groups for adjusted 5-year disease-related survival rates.

CONCLUSION

Properly supervised trainees can resect a high proportion of colorectal cancers without compromising immediate outcome or long-term survival.

The use of atypical antipsychotics in the management of schizophrenia

Long-term drug treatment of schizophrenia with conventional antipsychotics has limitations: an estimated quarter to one third of patients are treatment-resistant; conventional antipsychotics have only a modest impact upon negative symptoms (poverty of thought, social withdrawal and loss of affect); and adverse effects, particularly extrapyramidal symptoms (EPS). Newer, so-called atypical, antipsychotics such as olanzapine, risperidone, sertindole and clozapine (an old drug which was re-introduced in 1990) are claimed to address these limitations. Atypical agents are, at a minimum, at least as effective as conventional drugs such as haloperidol. They also cause substantially fewer extrapyramidal symptoms. However, some other adverse effects are more common than with conventional drugs. For example, clozapine carries a significant risk of serious blood disorders, for which special monitoring is mandatory; it also causes troublesome drowsiness and increased salivation more often than conventional agents. Some atypical agents cause more weight gain or QT prolongation than older agents. The choice of therapy is, therefore, not straightforward. At present, atypical agents represent an advance for patients with severe or intolerable EPS. Most published evidence exists to support the use of clozapine, which has also been shown to be effective in schizophrenia refractory to conventional agents. However, the need for compliance with blood count monitoring and its sedative properties make careful patient selection important. The extent of any additional direct benefit offered by atypical agents on negative symptoms is not yet clear. The lack of a depot formulation for atypical drugs may pose a significant practical problem. To date, only two double-blind studies in which atypical agents were compared directly have been published. Neither provides compelling evidence for the choice of one agent over another. Atypical agents are many times more expensive than conventional drugs. Although drug treatment constitutes only a small proportion of the costs of managing schizophrenia, the additional annual cost of the use of atypical agents in, say, a quarter of the likely U.K. schizophrenic population would be about 56 M pound sterling. There is only limited evidence of cost-effectiveness. Atypical antipsychotics are not currently licensed for other conditions where conventional antipsychotics are commonly used, such as behaviour disturbance or dementia in the elderly. Their dose, and place in treatment in such cases have yet to be determined.

The motivation to learn: efficacy and relevance of the Oswestry postgraduate orthopaedic training programme

The efficacy and relevance of medical education has come under increased scrutiny in recent years. The shortening of basic surgical training and the introduction of 'seamless' higher surgical training has placed greater emphasis on the quality of education provided/facilitated by trainers. Additionally, study leave budgets are under increasing pressure from trainees wishing to attend courses or conferences, and regional postgraduate deans who wish to see a proportionally greater amount of training on an 'in-house' basis. Against this background we have reviewed the learning opportunities available on the Oswestry postgraduate programme to see if these opportunities provide adequate motivation to learn for the trainee.

Structuring ward rounds for learning: can opportunities be created?

This paper explores the ways in which ward rounds can be conducted to maximize educational opportunities, as part of a project to improve the effectiveness of on-the-job training (OJT) for hospital doctors. Ninety ward rounds taken by 24 trainers in the Anglia region were observed. Each observation produced a note of the ward round's structure and routines and of the contributions made to it by trainers and trainees. Teaching was a feature of all ward rounds and different types of rounds were valued for different reasons. A range of ward round structures was observed and, within each, a range of routines for conducting the round. Ward round structures fell into four categories, with almost three-quarters of trainers making no use of either pre- or post-round meetings. Where such meetings took place, however, opportunities for OJT were created and, in some cases, optimized through routines to encourage trainee contributions. Discussion time away from patients structured into ward rounds enabled trainers and trainees to take advantage of many opportunities to learn from service. Although unplanned and unsystematic opportunities for OJT do arise, far more reliable are those created through systematic planning and preparation. Trainers have choices to make about how they conduct ward rounds and by choosing to make use of pre- and/or post-ward round sessions, valuable opportunities for OJT can be created.
