What makes a good clinical teacher in medicine? A review of the literature.

Purpose The authors perform a review of the literature pertinent to the question, “What makes a good clinical teacher in medicine?” Method After framing the question, based on discussions of their own experiences with clinical teachers, the authors performed a search of the literature pertinent to the question, “What are the qualities of a good clinical teacher in medicine?” Between July and December, 2006, they reviewed titles from Index Medicus (1909–1966), PubMed (1966 to the present), PubMed Related Articles, and referenced articles. The initial selections were chosen by scanning pre-1966 Index Medicus title lists and post-1966 abstracts. Chosen articles were then read in their entirety, and those which described specific characteristics of clinical teachers were selected for inclusion. Qualitative analysis was used to identify themes. Results From 4,914 titles, 68 articles were selected for analysis—26 published before 1966, and 42 published after 1966. Four hundred eighty descriptors were identified and grouped into 49 themes, which were clustered into three main categories: physician, teacher, and human characteristics. Echoing the authors’ intuitive descriptions, noncognitive characteristics dominated the descriptions and themes. Conclusions Excellent clinical teaching, although multifactorial, transcends ordinary teaching and is characterized by inspiring, supporting, actively involving, and communicating with students. Faculty development programs and future research should focus on development of the noncognitive attributes of clinical teachers, as well as the knowledge and skills associated with effective teaching.

Assessment of intraoperative judgment during gynecologic surgery using the Script Concordance Test

OBJECTIVE We sought to develop a valid, reliable assessment of intraoperative judgment by residents during gynecologic surgery based on Script Concordance Theory. STUDY DESIGN This was a multicenter prospective study involving 5 obstetrics and gynecology residency programs. Surgeons from each site generated case scenarios based on common gynecologic procedures. Construct validity was evaluated by correlating scores to training level, in-service examinations, and surgical skill and experience using a Global Rating Scale of Operative Performance and case volumes. RESULTS A final test that included 42 case scenarios was administered to 75 residents. Internal consistency (Cronbach alpha = 0.73) and test-retest reliability (Lin correlation coefficient = 0.76) were good. There were significant differences between test scores and training levels (P = .002) and test scores correlated with in-service examination scores (r = 0.38; P = .001). There was no association between test scores and total number of cases or technical skills. CONCLUSION The Script Concordance Test appears to be a reliable, valid assessment tool for intraoperative decision-making during gynecologic surgery.

Urodynamics, the supine empty bladder stress test, and incontinence severity

Determine whether urodynamic measures of urethral function [(valsalva leak point pressure (VLPP), maximum urethral closure pressure (MUCP), functional urethral length (FUL)] and the results of the supine empty bladder stress test (SEBST) correlate with each other and with subjective and objective measures of urinary incontinence (UI).

Effect of aging on storage and voiding function in women with stress predominant urinary incontinence.

PURPOSE We investigated age related changes in urodynamic parameters in 2 large cohorts of women planning stress urinary incontinence surgery. MATERIALS AND METHODS Using a standardized protocol we obtained urodynamic parameters for participants in SISTEr (Stress Incontinence Surgical Treatment Efficacy Trial) and TOMUS (Trial of Mid-Urethral Slings) undergoing baseline noninvasive flow followed by filling cystometrogram and pressure flow study. The bladder contractility index (defined as detrusor pressure at maximum flow+5×maximum flow) and detrusor hypocontractility (defined as detrusor pressure at maximum flow less than 10 cm H2O) were also characterized. Patients excluded from analysis had undergone prior stress urinary incontinence surgery or had prolapse stage greater than II. Propensity score analysis controlled for the potential bias of combining participants from 2 clinical trials. Linear and logistic regression analysis adjusting for propensity score quintile was done to assess the association of age and an age cutoff (less than 65 vs 65 or greater years) with urodynamic parameters. RESULTS A total of 945 women (468 in SISTEr and 477 in TOMUS) were included in analysis. Mean age was 50 years in SISTEr (range 27 to 75) and 51 years (range 24 to 82) in TOMUS. Noninvasive maximum urinary flow decreased significantly with age (26.2 vs 22 ml per second, p=0.002). Noninvasive flow voiding time increased 2.7 seconds for each 10-year age increment and detrusor pressure at maximum flow decreased 2.1 cm H2O for each 10-year increase in age (each p=0.003). Hypocontractility was more likely in women 65 years old or older (OR 2.89, 95% CI 1.59, 5.27). The bladder contractility index was inversely related to age, decreasing a mean±SD of 7.68±1.96 cm H2O for each 10-year age increase (p<0.001). CONCLUSIONS In these 2 cohorts the observed changes in voiding parameters suggest that detrusor contractility and efficiency decrease with age.

Toxic shock syndrome after laminaria insertion

BACKGROUND Laminaria tents used to facilitate surgical abortion are rarely associated with significant infectious morbidity. CASE A parous woman in midpregnancy had laminaria placed in her cervix followed by a second set after 24 hours. Eight hours later, she presented with dyspnea, hives, fever, tachycardia, and hypotension. Antibiotic treatment was initiated and a dilation and evacuation procedure was performed. Amniotic membrane cultures showed a heavy growth of Staphylococcus aureus with staphylococcal enterotoxin C expression, compatible with toxic shock syndrome. CONCLUSION Laminaria cervical dilation might be associated with toxic shock syndrome.

Opinions of West Texas pharmacists about emergency contraception

Background The pharmacist’s role in dispensing emergency contraception (EC) has become controversial due to the intersection of personal and professional ethics. Therefore, to examine the issue of EC availability, we surveyed a sample of West Texas pharmacists. West Texas is a religiously and politically conservative region where no methods of EC have been made available. Objective to survey a sample of pharmacists in West Texas about their experience, beliefs, and knowledge of EC both before and after a presentation of the current literature about EC. Methods We asked a convenience sample of 75 pharmacists about their experience, beliefs, and knowledge of EC both before and after a presentation of the current literature about EC. Results Sixty-four (85%) pharmacists agreed to complete the study questionnaire. None carries EC in his/her pharmacy, and scientific understanding of EC was generally poor. Fourteen percent stated EC conflicts with their religious views, 17% considered it a method of abortion, 11% would not be willing to fill an EC prescription written by a doctor. 58% would be willing to offer EC over the counter. The presentation encouraged more to offer it over the counter, but in general did not significantly change their beliefs. Conclusion Our sample of West Texas pharmacists demonstrated very little experience with, a general lack of knowledge about, and some personal and religious objections to EC.

Mesh Exposure and Associated Risk Factors in Women Undergoing Transvaginal Prolapse Repair with Mesh

Objective. To determine frequency, rate, and risk factors associated with mesh exposure in women undergoing transvaginal prolapse repair with polypropylene mesh. Methods. Retrospective chart review was performed for all women who underwent Prolift Pelvic Floor Repair System (Gynecare, Somerville, NJ) between September 2005 and September 2008. Multivariable logistic regression was performed to identify risk factors for mesh exposure. Results. 201 women underwent Prolift. Mesh exposure occurred in 12% (24/201). Median time to mesh exposure was 62 days (range: 10–372). When mesh was placed in the anterior compartment, the frequency of mesh exposure was higher than that when mesh was placed in the posterior compartment (8.7% versus 2.9%, P = 0.04). Independent risk factors for mesh exposure were diabetes (AOR = 7.7, 95% CI 1.6–37.6; P = 0.01) and surgeon (AOR = 7.3, 95% CI 1.9–28.6; P = 0.004). Conclusion. Women with diabetes have a 7-fold increased risk for mesh exposure after transvaginal prolapse repair using Prolift. The variable rate of mesh exposure amongst surgeons may be related to technique. The anterior vaginal wall may be at higher risk of mesh exposure as compared to the posterior vaginal wall.

Teaching techniques in the operating room: the importance of perceptual motor teaching.

Purpose To identify sucessful teaching techniques in the operating room environment through examining the teaching of the midurethral sling (MUS) surgery. Method The authors distributed questionnaires with open-ended questions about teaching and learning MUS to 5 urogynecology attendings and 16 obstetrics–gynecology residents in spring 2010. In an effort to identify qualities of an effective sling teacher, the authors used grounded theory to determine common themes and to code participant responses for examples. Results Of 21 potential respondents, 14 (67%) returned questionnaires. The authors analyzed these and identified seven commonalities among effective sling teachers: they (1) emphasize anatomical landmarks (as determined by 64 total comments); (2) use perceptual-motor teaching (PMT; 38 comments); (3) encourage repetition (28); (4) promote early independence (34); (5) demonstrate confident competence (23); (6) maintain a calm demeanor in the operating room (20); and (7) exhibit a willingness to accept responsibility for mistakes and consequences (9). The second-most common attribute, using PMT, requires the teaching attending to emphasize the motor and tactile aspects of operating and involves incorporating not only what learners see but also what they feel. Conclusions The authors report seven qualities or techniques fundamental to good teaching practice in a high-stress, high-technology surgical environment, and they have identified the use of PMT, which to their knowledge has not been previously described. Teachers and learners in this study characterized PMT, which is likely generalizable to surgical procedures other than the MUS, as important. Future research should focus on exploring this technique in other surgeries.

Controlling anal incontinence in women by performing anal exercises with biofeedback or loperamide (CAPABLe) trial: Design and methods

The goals of this trial are to determine the efficacy and safety of two treatments for women experiencing fecal incontinence. First, we aim to compare the use of loperamide to placebo and second, to compare the use of anal sphincter exercises with biofeedback to usual care. The primary outcome is the change from baseline in the St. Marks (Vaizey) Score 24weeks after treatment initiation. As a Pelvic Floor Disorders Network (PFDN) trial, subjects are enrolling from eight PFDN clinical centers across the United States. A centralized data coordinating center supervises data collection and analysis. These two first-line treatments for fecal incontinence are being investigated simultaneously using a two-by-two randomized factorial design: a medication intervention (loperamide versus placebo) and a pelvic floor strength and sensory training intervention (anal sphincter exercises with manometry-assisted biofeedback versus usual care using an educational pamphlet). Interventionists providing the anal sphincter exercise training with biofeedback have received standardized training and assessment. Symptom severity, diary, standardized anorectal manometry and health-related quality of life outcomes are assessed using validated instruments administered by researchers masked to randomized interventions. Cost effectiveness analyses will be performed using prospectively collected data on care costs and resource utilization. This article describes the rationale and design of this randomized trial, focusing on specific research concepts of interest to researchers in the field of female pelvic floor disorders and all other providers who care for patients with fecal incontinence.

Prophylactic antibiotics to prevent urinary tract infection during clean intermittent self-catheterization (CISC) for management of voiding dysfunction after prolapse and incontinence surgery: a decision analysis

Introduction and hypothesisThe objective of this study is to estimate efficacy of prophylactic antibiotics in UTI prevention during CISC for postoperative voiding dysfunction after prolapse/incontinence surgery.MethodsWe constructed a decision tree model to evaluate risks and benefits of prophylactic antibiotics during CISC for voiding dysfunction after prolapse/incontinence surgery. The model randomized women requiring CISC to prophylactic antibiotics or no prophylaxis. Probabilities for UTI after CISC with or without prophylactic antibiotics, sequelae from antibiotic use or UTI, and utility values were obtained from published literature and practice quality assurance reviews. Main outcome was probability of experiencing no UTI or adverse event.ResultsUnder baseline assumptions, prophylactic antibiotics were favored in both models. In the true UTI model, prophylactic antibiotics had an 83.1% probability of no UTI or adverse events; 16.1% better than no prophylactic antibiotics.ConclusionsUsing decision analysis methods, prophylactic antibiotics are favored for prevention of UTI during CISC to manage voiding dysfunction after prolapse/incontinence surgery.
