The effect of propranolol versus placebo on resident surgical performance.
(17/2575)
PURPOSE: To determine whether propranolol can decrease surgical tremor and anxiety in residents performing ocular microsurgery without impairing patient or physician safety. METHODS: In this randomized, double-masked, crossover study, 5 third-year ophthalmology residents ingested a capsule containing either propranolol, 40 mg, or placebo 1 hour prior to performing ophthalmic microsurgery. All residents were healthy men under age 30 years. Prior to commencement of the study, all participants had successfully been administered a test dose of propranolol without side effects. The study took place over a 10-week period. At the conclusion of each case, both the resident and attending surgeon observer independently completed a form grading, on a sliding scale: (1) amount of overall tremor; (2) amount of tremor during placement of the first 3 sutures after lens or nucleus extraction; (3) anticipated difficulty of the case; (4) actual difficulty with the case; and (5) anxiety (surgeon only). In addition, the type of procedure performed, complications encountered, and surgeon side effects were recorded. The data were analyzed with a 2-way analysis of variance for unbalanced data. RESULTS: A total of 73 surgical cases were performed; the surgeons were administered propranolol for 40 cases and placebo for 33. As judged by the resident surgeon, there was a highly significant effect of propranolol in decreasing anxiety (P = .0058), reducing surgical tremor overall (P < .0001), and reducing tremor while placing the first 3 sutures following lens extraction (P < .0001). There was no treatment-by-surgeon interaction for any of the measures. Complications and difficulty of the case, as judged by both the resident and attending surgeons, were not significantly different in the propranolol versus placebo groups (P > .05). There were no side effects reported or observed in any of the surgeons. CONCLUSIONS: Propranolol, 40 mg, administered 1 hour prior to surgery, significantly decreases tremor and anxiety in the surgeon without untoward effects to the surgeon and the patient. However, it is unknown whether decreased tremor and anxiety improved surgical outcome. (+info)
A physician-centred intervention to shorten hospital stay: a pilot study.
(18/2575)
BACKGROUND: Studies of length of stay (LOS) in hospital usually focus on physician-independent factors. In this study, the authors identified physician-dependent factors and tested an intervention aimed at them to determine its effect on LOS. METHODS: A prospective comparison of LOS on 2 general medical wards in a tertiary care teaching hospital before and after the intervention. The pre-intervention (control) period and the intervention period were each 4 weeks. The intervention consisted of a checklist for planning management and discharge. RESULTS: Overall, the mean LOS was shorter during the intervention period than during the control period, but the difference was not statistically significant (12.0 and 14.4 days respectively, p = 0.13). The difference was significant on ward A (11.0 v. 14.7 days respectively, p = 0.02) but not on ward B (13.0 and 14.0 days respectively, p = 0.90). INTERPRETATION: An intervention at the level of the admitting physician may help to shorten LOS on a general medical ward. (+info)
A medicolegal curriculum for internal medicine residents.
(19/2575)
Many residents lack knowledge about medicolegal issues. To assess the ability of 64 primary care residents to learn legal medicine, we studied the impact of a medicolegal curriculum in a randomized, controlled study. We measured residents' medicolegal knowledge using a novel test, the Legal Medicine Evaluation (LME). We found that the mean LME score of residents exposed to the curriculum increased 15.5 points (on a 100-point scale) to 65.9 ( p <.01), while the mean LME score of control residents increased only 3.5 points, to 53.5 ( p =. 05). Clearly, residents can learn basic medicolegal principles. Thus, observed deficiencies in medicolegal knowledge most likely arise from inadequate medicolegal instruction. (+info)
Consistency, inter-rater reliability, and validity of 441 consecutive mock oral examinations in anesthesiology: implications for use as a tool for assessment of residents.
(20/2575)
BACKGROUND: Oral practice examinations (OPEs) are used extensively in many anesthesiology programs for various reasons, including assessment of clinical judgment. Yet oral examinations have been criticized for their subjectivity. The authors studied the reliability, consistency, and validity of their OPE program to determine if it was a useful assessment tool. METHODS: From 1989 through 1993, we prospectively studied 441 OPEs given to 190 residents. The examination format closely approximated that used by the American Board of Anesthesiology. Pass-fail grade and an overall numerical score were the OPE results of interest. Internal consistency and inter-rater reliability were determined using agreement measures. To assess their validity in describing competence, OPE results were correlated with in-training examination results and faculty evaluations. Furthermore, we analyzed the relationship of OPE with implicit indicators of resident preparation such as length of training. RESULTS: The internal consistency coefficient for the overall numerical score was 0.82, indicating good correlation among component scores. The interexaminer agreement was 0.68, indicating moderate or good agreement beyond that expected by chance. The actual agreement among examiners on pass-fail was 84%. Correlation of overall numerical score with in-training examination scores and faculty evaluations was moderate (r = 0.47 and 0.41, respectively; P < 0.01). OPE results were significantly (P < 0.01) associated with training duration, previous OPE experience, trainee preparedness, and trainee anxiety. CONCLUSION: Our results show the substantial internal consistency and reliability of OPE results at a single institution. The positive correlation of OPE scores with in-training examination scores, faculty evaluations, and other indicators of preparation suggest that OPEs are a reasonably valid tool for assessment of resident performance.

Correlates of family-oriented physician communications.
(21/2575)
BACKGROUND: Family orientation in patient care has long been one of the primary tenets of the practice of family medicine. Yet we know surprisingly little about how frequently family-oriented transactions occur in actual doctor-patient encounters, or about what other aspects of physician communication patterns might be associated with increased family orientation. The purpose of this study was to investigate both frequency and correlates of family orientation in a residency-based practice. METHODS: Sixty videotapes representing 38 second and third-year residents interviewing a range of multiethnic patients over a 2-year period at a community clinic were analysed for evidence of family-oriented communications, as well as other interaction behaviours such as information exchange and partnership building. Inter-rater agreement was 78%. RESULTS: Asking for medical information, clarifying patient information, and giving medical information and explanations were the most common types of resident actions. Family orientation was much less common, but was more frequently observed than the eliciting of a patient-centered agenda or suggestion of a psychosocial intervention or referral. Family orientation was associated with longer interviews, non-interpreted interviews, more physician questions and clarifying behaviours, and greater tendency to elicit the patient's agenda. CONCLUSIONS: Findings of this investigation suggest that family orientation in the medical interview is enhanced by having more time and a shared language, as well as a generally probing, clarifying, patient-centered style on the part of the physician.

Evaluation of laparoscopic skills: a 2-year follow-up during residency training.
(22/2575)
OBJECTIVE: To evaluate laparoscopic technical skill in surgical residents over a 2-year period. DESIGN: The laparoscopic technical skills of general surgical residents were evaluated using the MISTELS program. This provides an objective evaluation of laparoscopic skill, taking into account precision and speed. SETTING: Inanimate laparoscopic skills centre. PARTICIPANTS: Ten general surgical residents (5 PGY1, 3 PGY2 and 2 PGY3 residents) who were required to complete 3 structured laparoscopic tasks. OUTCOME MEASURES: A composite score incorporating precision and timing was assigned to each task. The paired t-test was used to compare performance of each resident at the 2 levels of their residency training for each task. Linear regression analysis was used to correlated level of training and total score (sum of all tasks). RESULTS: Linear regression analysis demonstrated a highly significant correlation between level of training and total score (r = 0.82, p < 0.01). There was a significant increase in scores in the cutting and suturing task over the 2-year period (p < 0.01). Transferring skills did not improve significantly (p = 0.11). CONCLUSIONS: Performance in the simulator improved over residency training and was correlated highly with postgraduate year. This simulator model is a valuable teaching tool for training and evaluation of basic laparoscopic tasks in laparoscopic surgery. (+info)
Teaching family practice residents breast cyst aspiration.
(23/2575)
OBJECTIVE: To conduct the first study of teaching family practice residents the technique of breast cyst aspiration (BCA) using the Toronto Breast Cyst Aspiration Model (TBCAM) in a workshop. To determine whether this training increases their likelihood of performing the procedure in the future. To discover how residents evaluate the workshop as a teaching method. DESIGN: Prospective parallel-group trial from August to November 1997. Baseline questionnaires were given to both experimental and control groups in August. The experimental group was given a 1.5-hour workshop and a postworkshop questionnaire. Both groups were then given 3-month follow-up questionnaires. SETTING: Family practice residency program at the University of Toronto. PARTICIPANTS: The experimental group consisted of 15 family practice residents from one university-affiliated hospital site. The control group consisted of 54 family practice residents selected from the remaining sites. MAIN OUTCOME MEASURES: Confidence score, likelihood of performing BCA, and effectiveness of the workshop rated on a Likert scale ranging from 1-low to 5-high; and knowledge of BCA rated from 0 to 7. RESULTS: Three months after the workshop, 62% of study subjects and 31% of controls were above the median confidence score of 3.2 (chi 2 3.4, P > .05); 76% of subjects but only 11% of controls were above the median knowledge score of 4 (chi 2 16.67, P < .001); and 75% of subjects and 34% of controls were above the median likelihood to perform score of 3 (chi 2 5.37, P < .05). Most (95%) workshop effectiveness scores were 4s or 5s. CONCLUSIONS: Workshop training resulted in higher confidence, greater knowledge, and more likelihood of performing BCA. The workshop using the TBCAM was evaluated as a highly effective way to teach BCA. (+info)
Induction for senior house officers. Part II: The departmental programme.
(24/2575)
This study was designed to examine the content and usefulness of departmental induction programmes to senior house officers (SHOs) and to explore perceptions of the usefulness of a range of topics to these trainees. A total of 64 SHOs, in five hospitals in the Anglia region, participated in semi-structured interviews up to 3 months after starting their post. The interviews investigated the content of any induction received and also examined what the trainees would have liked to have received. Almost half (29) of the SHOs also completed a questionnaire which examined the perceived usefulness of various induction topics for a trainee starting a new post. The results showed that, although a departmental induction programme is considered important and highly valued, a substantial minority of SHOs had not received one. Of this minority, 75% would have welcomed an induction. Where an induction had taken place, the focus was primarily upon timetables, tours and meeting people, however, a quarter of the questionnaire sample had not received a service timetable, a third had not met any consultants, two-thirds had received no introduction to clinical management, and two-thirds had received no information about how their consultants manage their patients. Thus, although many trainees receive an induction, important information may not be covered. A staged approach to departmental induction is recommended, using a short, high-quality, and comprehensive induction programme. Flexible and timely programmes, supported by comprehensive written information, will contribute to meeting the needs of trainees in an efficient and effective way. (+info)
