Lifetime risk of surgical management for pelvic organ prolapse or urinary incontinence.

The objective of our study was to estimate the age-specific incidence and lifetime risk of surgically managed pelvic organ prolapse (POP) and urinary incontinence (UI). Women aged 20 and older who underwent primary surgical management of POP or UI in 1993 were identified from the database of a health maintenance organization using ICD-9 codes and confirmed through chart abstraction. From a population of 147,719 women, 135 were identified who underwent prolapse surgery only, 82 incontinence only, and 34 surgery for both conditions. From the age-specific incidence, we estimated the lifetime risk of undergoing an operation by age 80 to be 11.8%. Our findings agree with a previous estimate that approximately 11% of women will undergo surgery for POP or UI by age 80. POP and UI appear to be common problems, undoubtedly affecting an even larger proportion of the women than suggested by this high cumulative incidence of surgery.

The functional and psychosocial impact of fecal incontinence on women with urinary incontinence.

OBJECTIVES: The study was undertaken to determine the impact of fecal incontinence (FI) on functional status and quality of life in women with urinary incontinence (UI). STUDY DESIGN: In 24 months 732 women completed a standardized assessment and questionnaire, including the Short Form (SF)-12 and Incontinence Quality of Life (I-QOL) scores. Analysis of variance was used to compare SF-12 scores between groups defined as having UI, FI, or both UI and FI. I-QOL scores in patients with UI or UI and FI were compared by using the Student t test. RESULTS: Of the 732 patients enrolled, 425 patients had either UI (n = 342, 80%), FI (n = 18, 4%), or both (n = 65, 15%). Greater impairment in physical functioning was seen in the group with UI and FI (38.6; P =.027) compared with the group with UI (42.4). Significant decreases in I-QOL scores were seen for the group with UI and FI compared with those with UI (P <.005). CONCLUSION: Fecal incontinence further reduces the functional status and quality of life of women with urinary incontinence.

Development of a bench station objective structured assessment of technical skills.

OBJECTIVE: We have previously shown that objective structured assessment of technical skills performed in an animal model was an innovative, reliable, and valid method of assessing surgical skills. Our goal was to develop a less costly bench station objective structured assessment of technical skills and to evaluate the feasibility, reliability, and validity of this exam. METHODS: A seven-station examination was administered to 24 residents. The tests included laparoscopic procedures (salpingostomy, intracorporeal knot tying, closure of port sites) and open abdominal procedures (subcuticular closure, bladder neck suspension, repair of enterotomy, abdominal wall closure). All tasks were performed using life-like surgical models. Residents were timed and assessed at each station using three methods of scoring: a task-specific checklist, a global rating scale, and a pass/fail grade. RESULTS: Assessment of construct validity, the ability of the test to discriminate among residency levels, found significant differences on the checklist, global rating scale, time for procedures, and pass/fail grade by level of training. Reliability indices calculated with Cronbach's alpha were 0.77 for the checklists and 0.94 for the global rating scale. Overall interrater reliability indices were 0.91 for the global rating scale and 0.92 for the checklists. Total cost for replaceable parts and facilities was $1900. CONCLUSION: The less costly and more portable bench station objective structured assessment of technical skills can reliably and validly assess the surgical skills of gynecology residents. This type of examination can be a useful tool to identify residents who need additional surgical instruction, provide remediation, and may become a mechanism to certify surgical skill competence.

Testing surgical skills of obstetric and gynecologic residents in a bench laboratory setting: validity and reliability.

OBJECTIVE: Resident surgical skills are acquired mainly through observing and later performing procedures in the operating room. Evaluation of surgical skills has traditionally been done through subjective faculty evaluation, a technique that has poor reliability and unknown validity. Our goal was to develop specific surgical tasks, both laparoscopic and open abdominal, that could be objectively and reliably evaluated in a bench laboratory setting. STUDY DESIGN: The prospective development of a reliable and valid resident surgical skills test in a bench laboratory setting was our goal. A written test of surgical knowledge and 12 skills tests were administered to 36 residents. Laparoscopic bench tasks were simulated with the use of a box and camera with a video display. Six laparoscopic tasks were assessed, including placing pegs on a board, running the bowel simulation, and other tasks that involve hand-eye coordination and manual dexterity. Open abdominal skills simulated incision closure, suturing a vaginal cuff, knot tying, and using a tie on a passer. Residents were timed at each given station and were given a rating score by 2 examiners. RESULTS: Knowledge scores showed a significant improvement by residency level. Assessment of construct validity (the ability to discriminate among residency levels) demonstrated significant differences on the rating of overall performance and individual tasks by level (determined by 1-way analysis of variance). Interrater reliability (agreement between 2 raters) with the use of intraclass correlation was 0.79 for the total score. The cost to administer the bench laboratory test was less than $50 and required 30 hours of faculty time. CONCLUSION: The results of this study suggest that surgical bench laboratory tasks can assess residents' surgical skills with good reliability and validity on most tasks. Our previous study, which used an animal laboratory, was expensive, and the bench laboratory model may provide an alternative means to assess surgical skills.

Development of an objective structured assessment of technical skills for obstetric and gynecology residents.

OBJECTIVE: To develop an objective structured assessment for evaluating surgical skills of obstetrics and gynecology residents and to evaluate the reliability and validity of the assessment. METHODS: A seven-station, objective, structured assessment of technical skills was administered to 24 residents. The test included laparoscopic procedures (port placement, salpingostomy, suturing, vessel ligation) and open abdominal procedures (hypogastric ligation, repair of enterotomy, salpingo-oophorectomy.) All surgical tasks were done on pigs. Residents were timed and assessed at each station using three methods of scoring, a task-specific checklist, global rating scale, and pass-fail grade. RESULTS: Assessment of construct validity (the ability of the test to discriminate among residency levels) found significant differences on the checklist and the global rating scale by residency level. Reliability indices calculated with Cronbach's alpha were 0.89 for the global rating scale and 0.89-0.95 for the individual skills checklists. Interrater reliability was 0.87 for the global rating scale and 0.78-0.98 for the checklists. CONCLUSION: Objective, structured assessment of technical skills can assess residents' surgical skills with high reliability and validity. These assessments have possible application for identifying residents who need additional training and might provide a mechanism to ensure competence of surgical skills.

Teaching and evaluating surgical skills.

OBJECTIVE: To examine how surgical skills are taught and evaluated in obstetrics-gynecology residency programs in the United States. METHODS: A questionnaire was mailed to the directors of all 266 residency programs in the United States and to second contact names at 51 sites. Directors were asked to evaluate how surgical skills are taught and evaluated and to rate the importance of specific techniques and procedures for residents at given points in resident training. RESULTS: Two hundred twenty-three surveys were returned (70%), representing 203 of 266 programs (76%). Among responding programs, 99% reported teaching surgical skills in operating rooms, 88% in lectures, 68% with bench procedures, and 54% with animal surgery. Twenty-nine percent indicated they had formal surgical skills curricula. A significantly higher percentage of those programs with formal curricula used animal surgery laboratories (81% versus 42%, P <.001) and were more likely to conduct formal skills assessments (88% versus 69%, P =.005) than programs without formal curricula. Overall, 74% of programs evaluated surgical skills. Of those, 56% reported using subjective faculty evaluations, 12% written evaluations (eg, checklists), 4% written and oral assessments, and 1% a test. Regardless of formal curricula, there was much agreement in respondents' ratings of 60 different skills and procedures as "essential," "important," "nice to know," or "unimportant. CONCLUSION: Most programs teach surgical skills in the operating room and through lectures. Only 29% of reporting programs provide formal surgical curricula. Evaluation of surgical skills is usually done by subjective evaluation, a technique with unknown validity and poor reliability.

Periurethral collagen injection: a long-term follow-up study.

OBJECTIVE: To determine the long-term success of the periurethral injection of collagen (Contigen(R), Bard UK) in women with genuine stress incontinence. PATIENTS AND METHODS: Sixty-one women with genuine stress incontinence were enrolled in a trial of periurethral collagen injections between 1 September 1990 and 31 August 1992. They were assessed at 1, 3, 6, 12 and 24 months after the last collagen injection. In 1998, their notes were reviewed, and a standardized questionnaire was sent to 46 women who were still alive and had undergone no further anti-incontinence surgery. RESULTS: Of the 53 women who were either known failures or who had follow-up information beyond 5 years, 26% were subjectively improved. Women who had a maximum urethral closure pressure of >20 cmH2O and those who had urinary incontinence for <10 years before their first injection were more likely to have had long-term success. There was no correlation between long-term success and the number of previous operations, body mass index, age or preoperative pad loss. Neither the number of injection sessions, total volume of collagen injected nor perceived bulking at the time of surgery affected long-term success rates. Of the 14 women who considered themselves subjectively improved, seven had daily incontinence and only one was completely dry. Urinary retention and urinary tract infection were the most common complications. In addition, one woman reported a flare-up of her skin test and transient 'flu-like symptoms 2 weeks after the injection, and one woman developed a right upper lobe pneumonia 2 weeks after the collagen injection. CONCLUSION: The long-term results of periurethral collagen injections are disappointing. We found no evidence to support the use of periurethral collagen injections in women with intrinsic sphincter deficiency, who had a higher failure rate than those with hypermobility. Further research is essential to develop agents that are not immunogenic, produce minimal inflammatory response and yet are durable.

Formal teaching of surgical skills in an obstetric-gynecologic residency.

OBJECTIVE: To describe a formal teaching program of basic surgical skills in an obstetric-gynecologic residency program and evaluate its effectiveness. METHODS: A surgical skills program was developed for all residents. Using bench and animal laboratory sessions, residents were given instruction and performed both laparoscopic and open abdominal procedures. All were given a pretest and were tested again 6 months later. Residents also evaluated their experiences. RESULTS: To date, the formal teaching sessions have been given to 24 residents, all of whom believed their confidence and technical skills improved as a result of the sessions. On a scale of 1 to 5, the median rating of the bench laboratory experience was 5 (range 4-5), and the pig laboratory was 5 (range 4-5). All residents believed the surgery sessions should be continued and the number of sessions increased. Preliminary evaluation indicated that time to suture a 10-inch incision decreased by 28%, from an average of 225 (standard deviation [SD] 51) seconds to 171 (SD 43) seconds (P < .001), and evaluation of surgical technique significantly improved at the second pretest (P = .013). Laparoscopic placement of pegs on a board in 2 minutes increased from an average of 5 (SD 2.5) to 7.3 (SD 2.6; P = .001). The cost of the bench laboratory sessions was minimal. Each pig was approximately $100, and the facility charge for each 4-hour laboratory session was $1500. CONCLUSION: When formal surgical training was given to obstetric-gynecologic residents, their surgical skills improved subjectively and objectively.

Parent characteristics, perceived health risk, and smokeless tobacco use among white adolescent males.

The results of this study indicate that father education, father use of smokeless tobacco, and adolescent risk perception contribute to the use of smokeless tobacco by white males 12 to 14 years of age. However, risk perception does not account for the correlation between parent characteristics and child behavior. Father education and child smokeless tobacco use are inversely related if the father does not use it, and they are directly related if the father does; this finding is consistent with theories of modeling but is contrary to the common observation that the use of some abusive substances is relatively low among adolescents in higher social and economic levels. We concluded that father characteristics should be considered in research and in programs pertaining to the use of smokeless tobacco by white adolescent males.
