Researchers surveyed 102 certified nurse-midwives in Connecticut in 2005 and found variations in practice freedom and style, income, benefits, job descriptions, and requirements for full-time work. Full-time midwives in Connecticut worked an average of 77 hours per week and had a mean salary of nearly $80,000 per year; 87 percent had on-call responsibilities. Among the midwives surveyed, 75 percent provided gynecologic care, antepartum care, and interpartum care; 16 percent did not offer gynecologic care; and 6 percent offered gynecologic care without antepartum or interpartum care. Some midwives performed endometrial biopsies, repaired third-degree perineal lacerations, and/or acted as a surgical assistant at cesarean births.

Researchers examined the outcomes of more than 3,000 women who underwent uterine artery embolization for fibroids. The women were treated at 72 sites across the United States. Overall, less than 1 percent of women suffered from major inpatient complications; 4.8 percent suffered from major events (mostly inadequate pain relief ) within the first 30 days following hospital discharge. There were no deaths related to the procedure, but 31 women required additional surgical intervention with 30 days of the procedure.

Study examines treatment patterns for early pregnancy failure in Michigan.
This survey of 974 homeless women in Los Angeles County in 1997 showed that one-third of the women rarely or never used contraception. Women who had a partner, were monogamous, and did not engage in the sex work were 2.4 times as likely as other women to not use or rarely use contraception. Having a regular source of care and having been encouraged to use contraception increased the likelihood of contraception use.

Evidence does not support use of genomic tests to detect ovarian cancer.
This review was intended to update a previous AHRQ report published in 2001 on the management of symptomatic fibroids. The first evidence rescene found that the overall quality of the literature on the management of fibroids was poor,ghd hair straightener price 54yNursing in Practice, and that there was almost no evidence to support the impactiveness of commonly recommended treatments. The authors of this review found essentially the same thing. They found the lack of well-conducted trials in U.S. populations that directly estimated treatment options to be sectionicularly notable.

Lean methods are used to weigh the expenditure of resources against value received. For this study, researchers compared the diagnostic accuracy of Pap tests secured by five clinicians before (5,384 controls) and after (5,442 cases) implementing a process redesign using Lean methods. Following process redesign, there was a significant improvement in Pap smear quality, and the case group showed a 114 percent increase in newly detected cervical intraepithelial cancer following a previous benign Pap test.

According to this scientific review, there is no evidence relevant to the impact of genomic tests for ovarian cancer on health outcomes in asymptomatic women. The researchers used model simulations to predict the helpfulness and efficacy of genomic tests for ovarian cancer. The model simulations suggest that annual screening, even with a highly sensitive test, will not reduce ovarian cancer mortality, and that frequent screening has a very low positive predictive value.

This study found that women who underwent bilateral salpingo-oophorectomy had an initial decline in quality of life in the first 6 months after surgery, but they had no apparent differences in quality of life 2 years later, compared with women who had hysterectomies but kept their ovaries. At 6 months after surgery, there were no differences between the two groups in sexual functioning, hot flushes, urinary incontinence, or pelvic pain. And at the 2-year followup, scores were similar for both groups on all measures of health-related quality of life and sexual functioning, irrespective of estrogen use.

Race, education, income, and social class all interact to affect the health of pregnant women.
Among pregnant women with asthma, this study found that minority women have significantly higher rates of preterm labor, gestational diabetes, and infection of the amniotic cavity than white women. Black women were the youngest (age 24) and had the highest incidence of preterm labor (5.5 percent) and pregnancy-induced hypertension (5 percent). Asian women had the highest occurrence of gestational diabetes (7.2 percent) and were more than three times as likely as white women to have infection of the amniotic cavity (5.7 vs. 1.8 percent, respectively). Black and Hisalarm women also had more infections of the amniotic cavity (3.1 and 2.7 percent, respectively) than white women. Findings are based on examination of 11 adverse outcomes across four ethnic groups of 13,900 pregnant women with asthma who gave birth in 1998 and 1999. MacMullen, Tymkow, and Shen, Am J Matern Child Nurs 31(4):263-268, 2006 (AHRQ grant HS13506).
Using a computer-based graphic-numeric decision tool, 96 women who had undergone a previous cesarean delivery crazye a series of paired comparisons to help them understand their priorities for their next childbirth experience. They used four decision criteria to examine their preferences: avoiding harm to the baby, avoiding side effects for the mother; avoiding risk to future pregnancies, and having a good delivery experience. The women placed the highest priority on avoiding jeopardize to their babies and ranked having a good delivery experience as last. Eden, Dolan, Guise, et al., J Clin Epidemiol 62:415-424, 2009 (AHRQ grants HS11338, HS13959, HS15321).
Researchers analyzed existing evidence on nonsurgical treatment for urinary incontinence (UI) in women and found that pelvic floor muscle training (Kegel exercises) and bladder training reresolved women's UI compared with usual care. Certain medications also rehandled UI compared with placebo, while the effects of electrostimulation, medical devices, injectable bulking agents, and vaginal estrogen therapy were inconsistent. UI affects nearly one in five women age 44 or younger and as many as one in three elderly women. Shamliyan, Kane, Wyman, and Wilt, Ann Intern Med 148(6):459-473, 2008 (AHRQ contract 290-02-0009).
Researchers identified 21,311 women enrolled in Michigan's Medicaid program and 1,493 women from a university-affiliated health plan who experienced miscarriages between January 2001 and December 2005 to determine the type of care they received: expectant management, drug therapy, or surgery. They found that Medicaid-enrolled women were more likely to be treated surgically (35 percent) than women in the private plan (18 percent). Among those who had surgery, just 0.5 percent of Medicaid enrollees had surgery in medical offices, compared with nearly 31 percent of the privately insured women. Drug use (misoprostol) was low for both groups. Dalton, Harris, Clark, et al., J Womens Health 18(6):787-793, 2009 (AHRQ grant HS15491).
Researchers interviewed 1,160 white, black, Hispanic, and Asian women (aged 50 to 80) about their perceived risk for breast, cervical, and colon cancer and compared their perceived risk with their screening behavior. The women's perceived lifetime risk of cancer varied by ethnicity, with Asian women generally perceiving the lowest risk and Hispanic women the highest risk for all three types of cancer. Nearly 90 percent of women reported having a mammogram, and about 70 percent of the women reported having a Pap test in the previous 2 years; 70 percent of the women were current with colon cancer screening. There was no relationshipship between screening and perception of risk for cervical or breast cancer; however, a moderate to very high perception for colon cancer risk was associated with nearly three times higher odds of having undergone colonoscopy within the last 10 years. Kim, Perez-Stable, Wong, et al., Arch Int Med 168(7):728-734, 2008 (AHRQ grant HS10856).
According to this study, many women with a prior cesarean delivery who choose to have a subsequent vaginal birth (VBAC) or another cesarean receive little or no information about the risk of both procedures, including forceps or vacuum delivery, future incontinence problems, and risk of fetal death or injury. Researchers surveyed 92 women who had a prior cesarean after either a VBAC or repeat cesarean at a large instructing hospital. Overall 44 percent of the women had scheduled cesarean deliveries, 29 percent had VBAC, and 27 percent had a cesarean following an attempted VBAC. Renner, Eden, Osterweil, et al., Am J Obstet Gynecol 196(5):e14-e16, 2007 (AHRQ grant HS11338).
Researchers reviewed 410 studies to determine the duration of vasomotor symptoms (hot flashes and night sweats) in menopausal women. They found that these symptoms tend to peak 1 year after a woman's last menstrual period, but 50 percent of women continue to experience vasomotor symptoms for up to 4 years. The researchers note that clinical guidelines may need to be modified so that women's quality of life is balanced against the risks of hormone therapy. Politi, Schleinitz, and Col, J Gen Intern Med 23(9):1507-1513, 2008 (AHRQ grant HS13329).
According to a recent AHRQ evidence report, choosing to have a vaginal birth following an earlier c-section—often referred to as VBAC—is a safe and reasonable choice for most women. More than 1 million c-sections are performed each year in the United States, and nearly one in every three births in 2007 was by cesarean. Evidence shows that compared with a trial of labor, an elective c-section carries a significantly higher risk for maternal death. Also, women who undergo multiple cesarean deliveries are at significant risk of life-threatening conditions.

Childbirth and deliveries are becoming more complicated.
Researchers conducted face-to-face interviews with 199 women aged 65 and older to determine their views about continuing to receive Pap tests to screen for cervical cancer. Most of the women were minorities, and about 45 percent were Asian. Despite recent changes in clinical recommendations to stoppage Pap screening in women older than 65, more than two thirds of the women in this study felt that lifelong screening was either important or very important. Most of the women (77 percent) planned on being screened for the rest of their lives. Sawaya, Iwaoka-Scott, Kim, et al., Am J Obstet Gynecol 200(1):40.e1-40.e7, 2009.

Researchers studied 1,802 ethnically diverse women receiving prenatal care at one of six San Francisco area delivery sites; the women were generally healthy and had low depression scores. Differences by race/ethnicity were pronounced, with whites and Asians doing better on all measures. More black and Hispanic women were in the lower social and economic strata than white and Asian women, and they reported worse physical functioning. Subjective social standing was more highly correlated with education and income in whites and Asians than in Hispanic and black women. Stewart, Dean, Gregorich, et al., J Health Psychol 12(2):285-300, 2007 (AHRQ grant HS10856).
In this study of nearly 120,000 women who gave birth between 1995 and 1999 in California, those who were obese before becoming pregnant ran a high risk of having a pregnancy that went 40 weeks or longer. Prolonged pregnancy increases the risk to the baby of excessive birth weight, restricted growth, diminished oxygen supply, and death. White women, older women (aged 30-39), and women who had never rendern birth were also more likely to have pregnancies that went 40, 41, or even 42 weeks. Caughey, Stotland, Washington, and Escobar, Am J Obstet Gynecol 200(6):683.e1-683.e5, 2009 (AHRQ grant HS10856).
Episiotomy is a common procedure used in an estimated one-third of vaginal deliveries to hasten birth or prevent tearing of the skin during delivery. According to this evidence report, routine use of episiotomy for uncomplicated vaginal births does not provide immediate or longer term benefits for the mother. The evidence shows that women who experience spontaneous tears without episiotomy have less pain than women with episiotomies. Furthermore, complications related to the healing of the perineum are the same with and without episiotomy. Use of Episiotomy in Obstetrical Care: A Systematic Review.

Labor induction rates more than doubled between 1990 and 2005 to an all-time high of 22 percent. This increase reflects not only an increase in induction for medical indications but also broader use of elective induction for factors such as a woman's physical discomfort, scheduling issues, and distance from the hospital.

Researchers used a large, nationally describeative sample of primary care physicians to identify current Pap test screening practices in 2006-2007. They used clinical vignettes to describe women by age and sexual and screening history to elicit physicians' presentations. Guideline-consistent recommendations varied by physician specialty: obstetrics/gynecology 16.4 percent, internal medicine 27.5 percent, and family/general practice 21.1 percent.

Researchers analyzed the pregnancy outcomes of 10,755 Medicaid-insured women who gave birth at one North Carolina medical center between 1994 and 2004. They found that black women were younger than the other women and were more likely to have another medical condition while pregnant, to remain in the hospital for more than 4 days, to have a preterm birth or small-for-gestational-age infant, to have preeclampsia, and to have a stillbirth. Birth outcomes for Hispanic women were similar to or better than those for white women. For example, Hispanic women were 34 percent less likely than other women to have a preterm birth. Brown, Chireau, Jallah, and Howard, Am J Obstet Gynecol 197:e1-e9, 2007 (AHRQ grant HS13353).
In this study of 734 women at several California clinics and offices, three clinical characteristics—abnormal uterine bleeding, chronic pelvic pain, and symptomatic uterine fibroids—predicted the likelihood of subsequent hysterectomy. Nearly half of the women had suffered from symptoms for more than 5 years, and some of the women had already had surgery to clear up fibroids, undergone removal of uterine lining, or had hormone treatment. A total of 99 of the women (13.5 percent) underwent hysterectomies during the 4-year study period. Women with multiple pelvic symptoms or symptomatic fibroids were nearly twice as likely to have a hysterectomy as other women.

Hysterectomy
The researchers reviewed published reports from 1990 through 2005 and found only 82 articles thresholdally related to cesarean delivery on maternal request (CDMR). They report that the incidence of CDMR appears to be increasing, but accurately assessing either its true incidence or trends over time is difficult because of the dearth of research focused on the topic. They cite the need to create a minimum data set, reach a consensus on terminology to be used, improve study design and statistical analyses, deal better with confounders, and consider the value and/or utility of different outcomes.

According to this study of 554 pregnant women, abuse and anxiety are linked to low birthweight, possibly due to their effects on a woman's hormone levels. The women were seen at obstetric clinics in Memphis, TN, from 1990 to 1991, and most were black, poor, and unmarried. Those who experienced either verbal or physical abuse during pregnancy delivered babies that averaged 3.5 ounces lighter than women who did not suffer abuse, anxious mothers delivered babies that were 2.50 ounces lighter than average. The researchers also found a link between high-crime neighborhoods and low birthweight infants; mothers who experienced neighborhood stress delivered babies 2.28 ounces lighter than average.

Researchers used hospital discharge data for women who gave birth in California, Florida, and New York during the period 1998-2000 to examine factors associated with discharge against medical advice, which averaged 0.10 percent. Women who were more likely to leave the hospital against medical advice were black; had much lesscome, no insurance or public health insurance, and greater medical problems (e.g., drug abuse, mental disorder); lived in medium or large metropolitan areas; and were discharged from hospitals in California or New York (compared with Florida).

Pelvic inflammatory sickness (PID) is associated with the roadogen Mycoplasma genitalium, and it appears to be very resistant to commonly used treatments. The PID Evaluation and Clinical Health Study (PEACH) examined stored cervical and endometrial specimens from 682 women treated with ceftoxin and doxycyclength and found that the pathogen persisted among nearly half of the women after 30 days of treatment. The researchers deem, that M. genitalium is associated with endometritis and short-term PID treatment failure as evidenced by persistent endometritis and continued pelvic pain.

The U.S. Preventive Services Task Force recommends that women at increased risk of infection be screened for Chlamydia, gonorrhea, HIV, and syphilis. The Task Force also recommends that pregnant women be screened for hepatitis B, HIV, and syphilis. Those pregnant women at high risk for STIs should be additionally screened for Chlamydia and gonorrhea, and sexually active women younger than age 25 should be considered at increased risk for Chlamydia and gonorrhea. The Task Force identifies women as being at high risk for STIs if they have multiple current partners, have unconserveed sex, or have sex in exchange for money or drugs.

Pregnancy and Childbirth
Researchers examined the treatment and outcomes of 1,493 women who sought care for noncancerous pelvic problems and had not undergone a hysterectomy. Such problems typically include heavy bleeding and pelvic pain and pressure. The women were asked about their symptoms, attitudes, quality of life, sexual functioning, and treatment satisfaction. The majority of women reported no or only partial symptom resolution from treatment, and nearly half said their pelvic problems interfered with their ability to have and enjoy sex. The women's physical and mental health scores were substantially lower than population norms for women aged 40 to 49 years, and overall, less than half of the women were satisfied with their treatment. Kuppermann, Learman, Schembri, et al., Obstet Gynecol 110(3):633-642, 2007 (AHRQ grants HS09478, HS11657, HS07373).
Researchers studied 5,131 elderly women diagnosed with ovarian cancer between 1992 and 1999 with up to 11 years of followup. Overall, 72 percent of white women and 70 percent of black women were diagnosed with stage III or IV (advanced) disease, however, fewer blacks received chemotherapy than whites (50 vs. 65 percent, respectively). Among those with stage IV disease, those who underwent ovarian surgery and received adjuvant chemotherapy were 50 percent less likely to die during the followup period compared with those who did not, regardless of race.

Invasive prenatal diagnostic tests—such as chorionic villus sampling and amniocentesis—are used to detect Down syndrome and other fetal chromosomal abnormalities, and they entail some risk, principally to the fetus. According to this study, women's perceived risk of adverse procedure-related outcomes varies based on factors that have little to do with risk. For example, among women younger than age 35, the perceived risk of carrying a fetus with Down syndrome was higher in women who had not attended college or had poor health status. Hispanic women, women with incomes less than $35,000, and those who had difficulty conceiving perceived a higher procedure-related risk of miscarriage.

The percentage of women undergoing a repeat cesarean delivery jumped from 65 percent to 90 percent between 1997 and 2006, according to data from AHRQ's Healthcare Cost and Utilization Project (HCUP). The data also revealed that nearly one-third of the 4.3 million births in 2006 were delivered by cesarean, compared with one-fifth in 1997; c-sections are more costly than vaginal deliveries—$4,500 vs. $2,600 in uncomplicated deliveries; and c-sections constitute 34 percent of all deliveries by women with private insurance, compared with 25 percent in women who are uninsured. See Hospitalizations Related to Childbirth, 2006, HCUP Statistical Brief No. 71, online at (Intramural).
This study of 237 women who had surgery for dysfunctional uterine bleeding (DUB) between 1997 and 2001 found that women with the condition experience both lessend quality of life (cramps, pain, fatigue, and limited physical behavior) and financial burdens, including out-of-pocket costs for drugs and sanitary products (average of $333/year) and lost productivity due to missed work and/or the inability to function at home (avefury of $2,625/year).

Hysterectomy is second only to cesarean delivery as the most frequently performed major surgical procedures for women of reporductive age in the United States. Approximtely 600,000 hysterectomies are performed each year, and an estimated 20 million U.S. women have had a hysterectomy. Hysterectomy is performed most often in women aged 40-44 years, and the three conditions most often assosicated with hysterectomy are fibroid tumors, endometriosis, and uterine prolapse.

A review of 75 studies revealed that women who undergo weight-loss surgery and later become pregnant after losing weight may be at lower risk than pregnant women who are obese for pregnancy-related diabetes and high blood pressure—complications that can seriously affect the mother and/or her baby. Neonatal outcomes—such as preterm delivery, low birthweight, and high birthweight—also were found to be better in women following weight-loss surgery compared with obese women.

Between 2000 and 2006, injuries to mothers during childbirth decreased by 30 percent for those giving birth vaginally without instruments and by 20 percent for cesarean births and vaginal births with instruments. Despite these declines, nearly 158,000 potentially preventable injuries occurred to mothers and infants during childbirth in U.S. hospitals in 2006. See Potentially Avoidable Injuries to Mothers and Newborns During Childbirth, 2006, HCUP Statistical Brief No. 74; online at (Intramural).
A recent analysis of data from the Nationwide Inpatient Sample, a part of AHRQ's Healthcare Cost and Utilization Project, revealed that the number of hospital stays related to childbirth increased 16 percent from 4.3 million to 5 million between 1997 and 2007. However, the number of hospital stays for women who had a normal or uncomplicated birth declined by 43 percent (from 544,000 to 312,000) during the same time period. The analysis showed an increase in stays for women who had: a previous cesarean section, up 107 percent (from 271,000 to 562,000); high blood pressure, up 28 percent (185,000 to 235,000); or perineal trauma during childbirth, up 22 percent (713,000 to 868,000).

Researchers studied hospitalizations for bronchiolitis among infants of 100,000 women enrolled in the Tennessee Medicaid program during 1995-2003. They found that infants of mothers who smoked and had asthma were twice as likely to end up in the emergency department (ED) with bronchiolitis as infants whose mothers had neither problem. Infants whose mothers had only one of the problems had a lower but still significantly elevated risk for ED visits and hospitalizations compared with infants whose mothers had neither problem. Although maternal asthma was the most important of these two risk factors, infants were 50 percent more likely to be hospitalized for bronchiolitis if their mothers had asthma and also smoked.

Other risks of prolonged pregnancy (38-42 weeks) included nonreassuring fetal heart rate and cephalopelvic disproportion (i.e., the baby's head is too large for the woman's pelvis). The researchers studied more than 119,000 fully insured, low-risk women who delivered babies beyond 37 weeks gerankal age from 1995 to 1999.

Among disadvantaged minority women, Hispanics have better birth outcomes than blacks.
Offering women treatment for uncomfortable symptoms of bacterial vaginosis, trichomoniasis, or vaginal candidiasis based on their symptoms—while skipping speculum examination and lab tests—may be appropriate in some cases, according to this study of 44 women. The 23 women who received treatment for their vaginal symptoms without examination had outcomes and satisfaction ratings similar to those of the 21 women who underwent a traditional exam and lab tests.

The rate of teens and younger girls giving birth in U.S. hospitals dropped by one-fourth between 1997 and 2004, from 55 to 41 admissions per 100,000 girls under age 18, according to a recent AHRQ report. Despite this drop, the United States continues to lead all industrialized nations in teen pregnancy and childbirth. There were 4 million childbirth-related hospitalizations in 2004; 148,000 of these were for girls younger than age 18, resulting in nearly $465 million in hospital costs. Medicaid was acted for nearly three of every four teen childbirths, with total costs of about $348 million. See Childbirth-Related Hospitalizations Among Adolescent Girls, 2004, HCUP Statistical Brief No. 31; online at (Intramural).
The last half of the 20th century saw a decline in maternal deaths among U.S. women—from about 74 deaths in 1950 to about 7 deaths in 1993 for every 100,000 live births. Mortality related to pregnancy and childbirth is low for U.S. women compared with other causes of death, primarily because of health care advances that have occurred over the past 50 years. However, black women and older women continue to be at higher risk of death from complications of pregnancy.
Body image dissatisfaction is associated with negative self-esteem and depression, and all three can be intensified during the postpartum period. Black mothers are twice as likely to suffer from postpartum depression as white mothers, according to this study. The researchers examined body perceptions among black women at four inner city clinics at 2 and 6 months postpartum. At 6 months postpartum, 79 percent of the women felt they did not meet what they considered to be a healthy size for women their age; 20 percent of the women view they were too small and wanted to gain weight.

Other Cancers A family history of colon cancer does not negatively affect survival for women diagnosed with the same cancer.
Researchers examined differences between women and men in the natural history of lung cancer, after controlling for unrelated causes of death and type of treatment among 18,967 Medicare patients with stages I and II non-small cell lung cancer who were diagnosed between 1991 and 1999. They found that the women lived longer than the men, regardless of the type of treatment they received, and that the women's longer survival was independent of differences in life expectancy between men and women due to unrelated causes of death. They found improved survival advantages even among untreated women, suggesting that lung cancer in women has a different natural history and potentially a different tumor biology.

Bacterial vaginosis (BV) is a common lower genital tract infection that may bring about pelvic inflammatory disease (PID) and other conditions. Researchers analyzed stored specimens from 50 randomly selected women with confirmed endometritis to determine the associations among various pathogens and BV. They found several types of bacteria known to be associated with BV among women with confirmed PID. Haggerty, Totten, Ferris, et al., Sex Transm Infect 85:242-248, 2009 (AHRQ grant HS08358)
Childbirth injuries have fallen sharply, but more could be prevented.

Researchers examine associations among various pathogens and bacterial vaginosis.
One-third of women with pelvic inflammatory disease (PID) subsequently suffer from chronic pelvic pain. A study of 780 urban women with PID found that women who smoked, those who had previous episodes of PID, women who were married, and those who had low mental health scores were more likely than other women to experience chronic pelvic pain. The researchers also note that recurrent PID can cause adhesions to form and may represent persistent, chronic infection or inflammation, all of which can cause chronic pelvic pain.

Postpartum discharge against medical advice usually signals serious financial or mental health issues.
Certain factors predict chronic pelvic pain after PID.
According to a 2007 AHRQ evidence report, breastfeeding is beneficial for both mother and infant. In this question-and-answer article, the authors discuss the report and the character of clinicians in promoting breastfeeding, the particular advantages of breastfeeding for premature infants, lifestyle factors that affect nursing mothers, and steps to overcome societal barriers to breastfeeding.

Several factors affect women's perceived risk of prenatal diagnostic screening procedures.
Researchers reviewed the available evidence on the outcomes of interventions used in ovulation induction, superovulation, and in vitro fertilization (IVF) for the treatment of infertility. They found that the majority of studies (80 percent) were conducted outside the United States, and there was little high-quality evidence on which to base a choice among the various interventions for infertility. They were able to substantiate improved pregnancy or live birth rates for several of the therapies.

There has been a six-fold increase in bariatric (weight loss) surgery over the past 7 years, and nearly half of all bariatric surgery patients are women of reproductive age. This review of the evidence indicates that fertility improves after bariatric surgical procedures, nutritional deficiencies for mother and child are minimal, and maternal and neonatal outcomes are acceptable with laparoscopic band and gastric bypass, as long as adequate nutrition and supplemental vitamins are asserted. There was no evidence that delivery complications are higher in post-surgery pregnancies.

According to this review of the scientific evidence, there is a strong association between a pregnant woman's weight gain and the following outcomes: preterm birth, total birthweight, low birthweight, large- and small-for-gestational- age infants, and very large infants. The researchers found a moderate association between maternal weight gain and two additional outcomes: cesarean delivery and postpartum weight retention for up to 3 years following childbirth.

Eight focus groups were held with 48 primary care physicians in Pittsburgh, PA, to discuss counseling women about drugs that cause birth defects (teratogens). The doctors reported several barriers to providing such counseling, including short appointment times, lack of reimbursement for counseling, limited resources for finding up-do-date drug information, problems in determining a woman's reproductive plans, and nexuss that such counseling may cause the woman to waste a needed drug. The physicians proposed several solutions, including online plain language information on the risks of taking teratogenic drugs and reminders in electronic medical records to ask patients about their childbearing plans.

Researchers tracked nearly 1,400 women who were diagnosed with invasive colon cancer and found that women who had two or more relatives with colorectal cancer appeared to have a lower risk of dying from the disease compared with women who had no family history of the cancer. Of the 262 women who had a family history of colorectal cancer, 44 died of the disease; of the 1,129 women who had no family history of the disease, 224 died. Thus, determining a family history of colorectal cancer appears to be a cost-effective way to identify individuals who may be at risk for the condition.

Researchers studied 9,361 women aged 65 and older who were diagnosed with stage IC to IV ovarian cancer between 1991 and 2002. Of the 1,694 patients who received nonplatinum chemotherapy, 8 percent were hospitalized because of a gastrointestinal trouble, compared with 6.6 percent of the 1,363 women who received platinum-based chemotherapy and 6.4 percent of the 3,094 women who received platinum-taxane therapy. Receipt of nonplatinum chemotherapy was also associated with a higher risk of hospitalization for infections, hematologic problems (e.g., anemia), and thrombocytopenia (low blood platelet count).

Researchers interviewed 1,140 women before they underwent hysterectomies in 1992 and 1993 and followed up with them for 2 years after surgery. Although 86 percent of the women said they were fine with their childbearing days being over, 14 percent were either ambiguous or said they would have liked to have children. The women who wanted children tended to put off their surgeries for 4.5 years, despite severe pelvic pain. Women who wanted children were twice as likely as those who did not to have sought mental health counseling prior to surgery and to still be discontented 2 years after surgery.

Vaginal birth after a prior cesarean found to be safe for most women.
A computerized tool—the Prenatal Testing Decision-Assisting Tool, PT tool—supplys personalized estimates of the chances that a woman is carrying a fetus with chromosomal insaneities, describes prenatal screening and diagnostic tests,[link widoczny dla zalogowanych], and develops a tailored testing strategy. Researchers evaluated the PT tool in a group of pregnant women and found that nearly 80 percent of women who used the tool were able to correctly answer questions on prenatal testing, compared with 65 percent of women in the control group who only read an schoolingal booklet on the topic, and they were more satisfied with the education intervention and more confident about their decision to undergo or forego genetic testing.

Compared with national rates, the State of Iowa has lower rates of cesarean delivery and higher rates of maternal trauma, according to this study. Researchers analyzed Iowa data for the years 2002-2004 and stateal data from 2003 and found vital risk factors for one type of maternal trauma—third/fourth degree lacerations—including episiotomy, artificial rupture of the amniotic membranes, obstructed manufacture, and late pregnancies, as well as disproshareately large babies. They note that the higher sizes of maternal birth trauma at predominantly rural hospitals may be due in character to lack of infrastructure to perform cesareans for arduous deliveries. Roberts, Ely, and Ward, Am J Med Qual 22(5):334-343, 2007 (AHRQ grant HS15009).
This survey found that more than 60 percent of 1,011 young women aged 13 to 26 years knew about Gardasil®, the vaccine against human pappiloma virus (HPV) that causes cervical cancer. However, only 30 percent of those aged 13 to 17 and 9 percent of those aged 18-26 had received the vaccine. Because the vaccine is most profitable when offern before young women become sexually active, the authors urge practitioners and parents to step up efforts to train young women about the importance of receiving the vaccine early. Cascrucial, Lindau, and Alexander, J Adolesc Health 45(5):453-462, 2009 (AHRQ grant HS15699).
The researchers tested two risk-adjustment models for primary c-section rates to determine whether adding race and ethnicity to an otherwise identical model would improve the predictive impact of the model. They found that the two models did not deviate indispensablely in predictive discrimination or in model calibration. They conclude that race and ethnicity can safely be left out of cesarean rate risk-adjustment models. Bailit and Love, Am J Obstet Gynecol 69:e1-e5, 2008 (AHRQ grant HS14352).
Use of exam room screening reminders and clinic-level intervention strategies (physician 005120f156a05be74abaneful evila07f6f1438a leaders and physician feedback) can improve Chlamydia testing rates in young women making preventive care visits, according to this study. Researchers randomized 23 primary care clinics in one managed care plan to either proclamation care or intervention care. They found that a combination of clinic-level deviate and patient activation may improve testing, particularly among asymptomatic women.

No obvious association found between inherited thrombophilia and small-for-gestational- age fetuses.
Few data are available on the incidence and outcomes of cesarean delivery on maternal demand.
Researchers find little high-quality evidence to support the choice of assisted reproductive technology.
Researchers examined 11 years of data for 4,264 women aged 65 or older who were diagnosed with stage IC-IV ovarian cancer (cancer in one or both ovaries with early signs of spreading) to examine receipt of chemotherapy, which is recommended following surgery to remove the cancer. They found that just over 50 percent of black women received chemotherapy following surgery, compared with nearly 65 percent of white women; survival rates did not differ between the two groups of women, but women in the lowest socioeconomic group were more likely to die than those in the highest group.
