Randomized trial of medical treatment versus hysterectomy for abnormal uterine bleeding: resource use in the Medicine or Surgery (Ms) trial.

OBJECTIVE: This study was undertaken to compare resource use outcomes for participants in the Medicine or Surgery (Ms) randomized trial. STUDY DESIGN: In a randomized controlled trial, we compared resources used during a 24-month follow-up period by women with abnormal uterine bleeding who were randomly assigned to either expanded medical treatment or hysterectomy. RESULTS: Women randomly assigned to hysterectomy used significantly more resources (medicine = $4479, hysterectomy = $6777; P = .03), with almost all the difference caused by the hysterectomy procedure. Fifty-three percent of women randomly assigned to medicine had a hysterectomy during the follow-up period; women who were able to continue on medical therapy had mean total resource use of $2595 compared with $6128 for medicine patients who eventually had surgery. CONCLUSION: For women with abnormal uterine bleeding refractory to cyclic medroxyprogesterone acetate, compared with expanded medical treatment, hysterectomy increases resource use significantly and results in better clinical and 6-month quality-of-life outcomes.

Beyond race or ethnicity and socioeconomic status: predictors of prenatal testing for Down syndrome.

OBJECTIVE: To identify predictors of prenatal genetic testing decisions and explore whether racial or ethnic and socioeconomic differences are explained by knowledge, attitudes, and preferences. METHODS: This was a prospective cohort study of 827 English-, Spanish-, or Chinese-speaking pregnant women presenting for care by 20 weeks of gestation at 1 of 23 San Francisco Bay-area obstetrics clinics and practices. Our primary outcome measure for women aged less than 35 years was any prenatal genetic testing use compared with none, and for women aged 35 years or older, prenatal testing strategy (no testing, screening test first, straight to invasive diagnostic testing). Baseline questionnaires were completed before any prenatal test use; test use was assessed after 30 gestational weeks. RESULTS: Among women aged less than 35 years, no racial or ethnic differences in test use emerged. Multivariable analyses yielded three testing predictors: prenatal care site (P = .024), inclination to terminate pregnancy of a Down-syndrome-affected fetus (odds ratio 2.94, P = .002) and belief that modern medicine interferes too much in pregnancy (odds ratio .85, P = .036). Among women aged 35 years or older, observed racial or ethnic and socioeconomic differences in testing strategy were mediated by faith and fatalism, value of testing information, and perceived miscarriage risk. Multivariable predictors of testing strategy included these 3 mediators (P = .035, P < .001, P = .037, respectively) and health care system distrust (P = .045). A total of 29.5% of screen-positive women declined amniocentesis; 6.6% of women screening negative underwent amniocentesis. CONCLUSION: Racial or ethnic and socioeconomic differences in prenatal testing strategy are mediated by risk perception and attitudes. Screening is not the best choice for many women. Optimal prenatal testing counseling requires clarification of risks and consideration of key attitudes and preferences regarding the possible sequence of events after testing decisions.

Abortion attitudes of pregnant women in prenatal care.

OBJECTIVE: This study was undertaken to describe abortion attitudes in a diverse cohort of pregnant women enrolled in prenatal care. STUDY DESIGN: A cross-sectional interview study of 1082 demographically diverse gravid women enrolled in prenatal care at less than 20 weeks' gestation was performed. RESULTS: Most participants (92%) supported abortion availability. Half (50%) who were willing to consider an abortion would do so only in the first trimester. Among the gravid women willing to consider an abortion in the first or second trimester, 84% would do so after rape/incest or if their life was endangered and 76% would if their fetus had Down syndrome. Gravid women considering abortion were more likely to be white, older, have had a previous abortion, and to express distrust in the health care system. Women who would not consider abortion were more likely to be multiparous, married/living with partner, and to express greater faith and fatalism about their pregnancy outcome. CONCLUSION: Although most pregnant women enrolled in prenatal care support abortion availability, about half would only consider a first-trimester procedure. These findings underscore the need for early prenatal genetic counseling, screening, and testing.

Obstetrics and gynecology resident satisfaction with an integrated, comprehensive abortion rotation.

OBJECTIVE: To evaluate obstetrics and gynecology resident satisfaction with a comprehensive, integrated abortion rotation. METHODS: The University of California, San Francisco obstetrics and gynecology residency program includes a 6-week PGY-3 family planning rotation at an in-hospital clinic where abortions are provided up to 23 weeks of gestation. Residents annually evaluate the educational value of all clinical rotations on a 5-point Likert scale, with 5 indicating "maximum value," and 1 "no value." Using data from 1998-2003, we compared ratings of the family planning rotation with all other PGY-3 rotations. We also surveyed residents 1 to 3 years after graduation to assess the rotation qualitatively and quantitatively. RESULTS: Forty residents completed the abortion training, none opted out of training, and all completed the evaluations. Of all rotations in the third year, the family planning rotation was the highest rated (4.70), was similar in value to a high-volume surgical rotation (4.51, P > .10) and the elective rotation (4.45, P >.05), and surpassed the average score for all inpatient rotations (4.00, P < .001), continuity clinic (4.10, P < .001), and outpatient clinical experiences (4.06, P <.01). According to residency graduates, the family planning rotation was rated 4.8 (where 5 indicates "far greater value" than other rotations), and 85% of respondents rated it of "maximum learning value". CONCLUSION: Obstetrics and gynecology residents place high value in the University of California, San Francisco PGY-3 family planning rotation during their training and in their first years of practice.

Sexual functioning after total compared with supracervical hysterectomy: a randomized trial.

OBJECTIVE: To compare sexual functioning and health-related quality-of-life outcomes of total abdominal hysterectomy (TAH) and supracervical hysterectomy (SCH) among women with symptomatic uterine leiomyomata or abnormal uterine bleeding refractory to hormonal management. METHODS: We randomly assigned 135 women scheduled to undergo abdominal hysterectomy in 4 U.S. clinical centers to either a total or supracervical procedure. The primary outcome was sexual functioning at 2 years, as assessed by the Medical Outcomes Study Sexual Problems Scale. Secondary outcomes included specific aspects of sexual functioning and health-related quality-of-life at 6 months and 2 years. RESULTS: Sexual problems improved dramatically in both randomized groups during the first 6 months and plateaued by 1 year. Health-related quality-of-life scores also improved in both groups. At 2 years, both groups reported few problems with sexual functioning (mean score on the Sexual Problems Scale for SCH group 82, TAH group 80, on a 0-to-100 scale with 100 indicating an absence of problems; difference = +2.95% confidence interval -8 to +11), and there were no significant differences between groups. CONCLUSION: Supracervical and total abdominal hysterectomy result in similar sexual functioning and health-related quality of life during 2 years of follow-up. This information can help guide physicians as they discuss surgical options with their patients.

Effect of hysterectomy vs medical treatment on health-related quality of life and sexual functioning: the medicine or surgery (Ms) randomized trial.

CONTEXT: Although a quarter of US women undergo elective hysterectomy before menopause, controlled trials that evaluate the benefits and harms are lacking. OBJECTIVE: To compare the effect of hysterectomy vs expanded medical treatment on health-related quality of life. DESIGN, SETTING, AND PARTICIPANTS: A multicenter, randomized controlled trial (August 1997-December 2000) of 63 premenopausal women, aged 30 to 50 years, with abnormal uterine bleeding for a median of 4 years who were dissatisfied with medical treatments, including medroxyprogesterone acetate. The participants, who were patients at gynecology clinics and affiliated practices of 4 US academic medical centers, were followed up for 2 years. INTERVENTIONS: Participants were randomly assigned to undergo hysterectomy or expanded medical treatment with estrogen and/or progesterone and/or a prostaglandin synthetase inhibitor. The hysterectomy route and medical regimen were determined by the participating gynecologist. MAIN OUTCOME MEASURES: The primary outcome was mental health measured by the Mental Component Summary (MCS) of the 36-Item Short-Form Health Survey (SF-36). Secondary outcomes included physical health measured by the Physical Component Summary (PCS), symptom resolution and satisfaction, body image, and sexual functioning, as well as other aspects of mental health and general health perceptions. RESULTS: At 6 months, women in the hysterectomy group had greater improvement in MCS scores than women in the medicine group (8 vs 2, P =.04). They also had greater improvement in symptom resolution (75 vs 29, P<.001), symptom satisfaction (44 vs 7, P<.001), interference with sex (41 vs 22, P =.003), sexual desire (21 vs 3, P =.01), health distress (33 vs 13, P =.009), sleep problems (13 vs 1, P =.03), overall health (12 vs 2, P =.006), and satisfaction with health (31 vs 14, P =.01). By the end of the study, 17 (53%) of the women in the medicine group had requested and received hysterectomy, and these women reported improvements in quality-of-life outcomes during the 2 years that were similar to those reported by women randomized to the hysterectomy group. Women who continued medical treatment also reported some improvements (P<.001 for within-group change in many outcomes), with the result that most differences between randomized groups at the end of the study were no longer statistically significant in the intention-to-treat analysis. CONCLUSIONS: Among women with abnormal uterine bleeding and dissatisfaction with medroxyprogesterone, hysterectomy was superior to expanded medical treatment for improving health-related quality-of-life after 6 months. With longer follow-up, half the women randomized to medicine elected to undergo hysterectomy, with similar and lasting quality-of-life improvements; those who continued medical treatment also reported some improvements.

How do women of diverse backgrounds value prenatal testing outcomes?

OBJECTIVES: To describe women's preferences for prenatal testing outcomes and to explore their association with sociodemographic characteristics and attitudes. METHODS: We conducted a cross-sectional study of 584 racially/ethnically and socioeconomically diverse pregnant women aged 16 to 47 years recruited from 23 San Francisco Bay Area practices. We assessed preferences for 12 potential prenatal testing outcomes using the time trade-off metric for all outcomes and the standard gamble metric for two outcomes. Preferences were calculated on a scale of 0 (death) to 1 (perfect health). Participants also completed a sociodemographic and attitude survey. RESULTS: Highest preference scores were assigned to outcomes resulting in the birth of a chromosomally normal infant (mean = 0.91-0.93; median = 0.99-1.00). Lower scores were obtained for outcomes involving pregnancy loss (mean = 0.69-0.87; median = 0.76-0.92), which were correlated with attitudes regarding miscarriage, pregnancy termination, and Down syndrome. The lowest scores were assigned to Down syndrome-affected births (mean = 0.67-0.69; median = 0.73-0.75), which also were correlated with attitudes toward Down syndrome. We did not find a statistically significant relationship between participants' preference scores and age. CONCLUSION: Preferences for prenatal testing outcomes vary according to the pregnant women's underlying attitudes about pregnancy loss and Down syndrome, and not according to her age. Current age/risk-based guidelines should account for individual variation in patient preferences.

Medicine or Surgery (Ms): a randomized clinical trial comparing hysterectomy and medical treatment in premenopausal women with abnormal uterine bleeding.

Hysterectomy may be overused as treatment for abnormal uterine bleeding due to benign causes in reproductive women. Medical therapies are an alternative, and there is a need for randomized trials comparing the outcomes of these approaches. Women of reproductive age who continued to have bothersome abnormal uterine bleeding after cyclic hormonal treatment with medroxyprogesterone acetate (MPA; 10-20 mg for 10-14 days/month) for 3-5 months were invited to participate in a randomized trial of hysterectomy versus other medical therapies. Participating gynecologists were free to choose the particular surgical (transabdominal or transvaginal) or medical (generally oral contraceptives and/or a prostaglandin synthetase inhibitor) approaches. Outcomes during 2 years of follow-up include quality of life (primary), sexual function, clinical effectiveness and cost. We screened 1557 women to find 413 who began 3-5 months of MPA; 215 completed this treatment, of whom 102 still had bothersome symptoms, and of these 38 consented to be randomized. Another 25 women with bothersome symptoms after a documented history of 3 months of cyclic MPA were also randomized, for a total of 63. The average age of randomized women was 41; 54% were African-American, and they reported uterine bleeding 12 days/month on average, heavy bleeding 6 days/month. Anemia (hematocrit<32) was present in 38% of African-Americans and 15% of Caucasians (p=0.05). Two thirds of the women had fibroids and 80% reported pelvic pain. Obesity was common (45% had a body mass index (BMI)>30), and associated with a longer duration of symptoms (12 vs. 4 years for BMI<25; p=0.02) and a greater prevalence of incontinence (44% vs. 16%; p=0.046). Although recruitment was difficult, we have completed enrollment in a randomized clinical trial comparing surgical and medical treatments for abnormal uterine bleeding.

Hysterectomy versus expanded medical treatment for abnormal uterine bleeding: clinical outcomes in the medicine or surgery trial.

OBJECTIVE: To compare clinical outcomes after randomization to hysterectomy versus medical treatment in patients with chronic abnormal uterine bleeding refractory to medroxyprogesterone acetate. METHODS: We randomly assigned 63 premenopausal women with abnormal uterine bleeding refractory to cyclic medroxyprogesterone acetate treatment to receive either a hysterectomy or expanded medical treatment. Within each randomized group, the specific treatment approach was determined by patient and provider preference. The primary analysis compared changes in clinical outcomes at 6 and 24 months by using an intention-to-treat approach. Secondary as-treated analyses after adjustment for baseline covariates compared participants randomly assigned to medical treatment who continued the medical approach with those who crossed over to hysterectomy. RESULTS: The intention-to-treat analyses at 6 months revealed greater symptom improvement in the hysterectomy group than in the medicine group for pelvic pain (P <.01), urinary urgency (P =.03), incomplete bladder emptying (P =.03), breast pain (P =.02), and cessation of vaginal bleeding (87% versus 11%, P <.001). Seventeen of 32 women assigned to medicine (53%) eventually crossed over and received a hysterectomy, and by 24 months the statistically significant differences by intention-to-treat were limited to greater improvement in hot flushes (P <.01) and cessation of vaginal bleeding (P <.01). Within-group analyses at year 2 showed statistically significant improvements from baseline on most symptoms for women who had a hysterectomy, whether through randomization or crossover. Women remaining on medical treatments had statistically significant improvements in pelvic pain, pelvic/bladder pressure, and stress incontinence. In a nonrandomized comparison with women who remained on medical treatments through year 2, those crossing over to hysterectomy experienced greater improvements in bleeding (P <.01), pelvic pain (P <.01), low back pain (P =.02), breast pain (P =.01), urinary frequency (P =.01), and urgency (P =.02). However, they also experienced more days off from work or usual activities (P <.01) and more days spent in bed (P <.01) than those who remained on medicine. CONCLUSION: For patients with abnormal uterine bleeding refractory to medroxyprogesterone acetate, hysterectomy is superior to expanded efforts with oral medications for alleviating clinical symptoms but may lead to more days of restricted activity.

Resource use for total and supracervical hysterectomies: results of a randomized trial.

OBJECTIVE: Hysterectomy is the most common major surgical procedure performed in the United States for nonobstetric reasons. Although most hysterectomies include removal of the cervix, the rate of supracervical procedures has increased in recent years. To provide evidence about the outcomes of both types of hysterectomy, we conducted a randomized clinical trial of total (TAH) or supracervical (SCH) hysterectomy (the "TOSH" trial). We report here an analysis of 24-month resource use by patients in this trial. METHODS: A randomized controlled trial was performed at 3 clinical centers to compare resources used by 120 patients who received a total or supracervical abdominal hysterectomy. Service use during a 24-month follow-up period was identified from medical and billing records and patient reports. Each service used was assigned a relative value, which was then converted into 2002 U.S. dollars. RESULTS: Overall resource use was similar in the 2 study groups in the first 12 months after randomization (TAH 5,870 US dollars; SCH 6,018 US dollars; 95% confidence interval for difference -960 US dollars, 1,255 US dollars; P <.79) and for the full 24 months (TAH 6,448 US dollars; SCH 7,479 US dollars; 95% confidence interval for difference -533 US dollars, 2,616 US dollars; P <.20). In exploratory multivariable analyses, resource use was significantly associated with baseline body mass index greater than or equal to 35 kg/m(2) (8,440 US dollars versus 6,398 US dollars, P =.02) and heavy bleeding (7,550 US dollars versus 5,368 US dollars, P =.02). CONCLUSION: We conclude that the use of medical care resources over a 24-month period is comparable for total and supracervical hysterectomy. The association of a woman's weight and bleeding pattern with subsequent resource use requires further investigation.

Social and familial context of prenatal genetic testing decisions: are there racial/ethnic differences?

The purpose of this cross-sectional study of 999 socioeconomically and racially/ethnically diverse pregnant women was to explore prenatal genetic testing attitudes and beliefs and the role of external influences. Surveys in English, Spanish, and Chinese included questions regarding the value of testing, pregnancy, and motherhood; the acceptability of Down syndrome in the subject's community; and the role of social and cultural influences in prenatal testing decisions. We analyzed racial/ethnic differences in all attitudinal and external influence variables, controlling for age, relationship status, and socioeconomic status. We found statistically significant racial/ethnic group differences in familiarity with an individual with Down syndrome and in 10 of 12 attitude, belief, and external influence variables, even after controlling for other sociodemographic characteristics. We also observed substantial variation within racial/ethnic groups for each of these measures. Despite the statistically significant group differences observed, R(2) values for all multivariate models were modest and response distributions overlapped substantially. Social and familial contexts for prenatal testing decisions differ among racial/ethnic groups even after accounting for age, marital status, and other socioeconomic factors. However, substantial variation within groups and overlap between groups suggest that racial/ethnic differences play a small role in the social and familial context of prenatal genetic testing decisions.

Effects of a depression education program on residents' knowledge, attitudes, and clinical skills.

OBJECTIVE: To determine whether an interactive educational program would improve obstetrics and gynecology residents' knowledge, attitudes, confidence, and skills in caring for depressed patients. METHODS: We recruited 74 residents from eight residency programs to attend the Depression Education Program, which consists of a 1-hour lecture and two 2-hour workshops combining discussion, diagnosis and treatment tools, critique of a videotape, practice with feedback, and audiotape self-assessment. Before and after the program, participants 1) completed a questionnaire measuring knowledge, attitudes, and reported actions taken with a recent depressed patient; 2) received a standardized patient visit; and 3) kept lists of patients they suspected were depressed. Clinic patients completed a depression screening questionnaire. To assess improvement, we used paired t tests, McNemar chi2 tests, and multivariate models adjusting for training site. RESULTS: The education program led to 3-month improvements in participants' reported use of formal diagnostic criteria (38% before, 66% after; P =.004), clinical actions documented for suspected depression (P =.035), and perceived self-efficacy in depression care (P <.001). Perceived preparedness to diagnose depression, treat with medications, and comanage with a mental health practitioner improved (P <.05 for each). Small improvements in clinical behaviors with standardized patients and clinic-based depression detection rates were not statistically significant. CONCLUSION: The Depression Education Program improved residents' knowledge, confidence, and reported clinical actions with depressed patients, but did not improve most objectively assessed outcomes.

A randomized comparison of total or supracervical hysterectomy: surgical complications and clinical outcomes.

OBJECTIVE: To compare surgical complications and clinical outcomes after total versus supracervical abdominal hysterectomy for control of abnormal uterine bleeding, symptomatic uterine leiomyomata, or both. METHODS: We conducted a randomized intervention trial in four US clinical centers among 135 patients who had abdominal hysterectomy for symptomatic uterine leiomyomata, abnormal uterine bleeding refractory to hormonal treatment, or both. Patients were randomly assigned to receive a total or supracervical hysterectomy performed using the surgeon's customary technique. Using an intention-to-treat approach, we compared surgical complications and clinical outcomes for 2 years after randomization. RESULTS: Sixty-eight participants were assigned to supracervical hysterectomy (SCH) and 67 to total abdominal hysterectomy (TAH). Hysterectomy by either technique led to statistically significant reductions in most symptoms, including pelvic pain or pressure, back pain, urinary incontinence, and voiding dysfunction. Patients randomly assigned to (SCH) tended to have more hospital readmissions than those randomized to TAH, but this difference was not statistically significant. There were no statistically significant differences in the rate of complications, degree of symptom improvement, or activity limitation. Participants weighing more than 100 kg at study entry were twice as likely to be readmitted to the hospital during the 2-year follow-up period (relative risk [RR] 2.18, 95% confidence interval [CI] 1.06, 4.48, P=.034). CONCLUSION: We found no statistically significant differences between (SCH) and TAH in surgical complications and clinical outcomes during 2 years of follow-up.

Medroxyprogesterone acetate treatment of abnormal uterine bleeding: factors predicting satisfaction.

OBJECTIVE: This study was undertaken to identify the determinants of patient satisfaction with a cyclic regimen of medroxyprogesterone acetate (MPA) for abnormal uterine bleeding. STUDY DESIGN: A prospective cohort study of 413 premenopausal women were treated for 3 to 5 months with oral MPA 10 to 20 mg per day for 10 to 14 days per month. We assessed satisfaction with and willingness to continue MPA. Baseline characteristics hypothesized to predict treatment satisfaction were entered into logistic regression analysis. RESULTS: Sixty-five percent of subjects (271) completed at least 3 months of MPA, 79% (215) filled out a satisfaction survey, and 57% (123) expressed satisfaction with MPA. Satisfaction was predicted by age 35 years or older (odds ratio [OR] 2.67, CI 1.07-6.7), desire for uterine conservation (OR 1.36, CI 1.11-1.66), perceived importance of stopping bleeding (OR 0.69, CI 0.54-0.87), and tubal sterilization (OR 0.52, CI 0.28-0.96). Neither bleeding history nor parity predicted MPA satisfaction. CONCLUSION: These findings underscore the importance of considering patient age, fertility status, attitudes about uterine conservation, and desire for definitive resolution of bleeding when deciding whether to use MPA versus other treatments for abnormal uterine bleeding.
