An economic comparison of female sterilization of hysteroscopic tubal occlusion with laparoscopic bilateral tubal ligation

Background

This study compares the expected 5-year costs for permanent sterilization in women between nonincisional hysteroscopic tubal occlusion with the Essure® system performed in an office setting and laparoscopic bilateral tubal ligation (LBTL).

Study Design

An economic decision tree is used to predict outcomes and costs to compare these two procedures from a US Medicaid perspective over a 5-year time horizon.

Results

Expected costs are $2367 for Essure® and $3545 for LBTL (Essure® saves $1178 or 33% of LBTL costs). Sensitivity analyses show Essure® has lower expected costs across all values considered. If the cost for a LBTL procedure were to decrease by 20% and the cost for Essure® to increase by 20%, Essure® would have still have lower expected costs.

Conclusion

Office-based sterilization for women using Essure® can lead to substantial cost savings over 5 years compared to LBTL. This conclusion is robust to varying analytic inputs.     

Reconsidering racial/ethnic differences in sterilization in the United States

Objective

Cross-sectional studies have found that low-income and racial/ethnic minority women are more likely to use female sterilization and less likely to rely on a partner’s vasectomy than women with higher incomes and whites. However, studies of pregnant and postpartum women report that racial/ethnic minorities, particularly low-income minority women, face greater barriers in obtaining a sterilization than do whites and those with higher incomes. In this paper, we address this apparent contradiction by examining the likelihood a woman gets a sterilization following each delivery, which removes from the comparison any difference in the number of births she has experienced.

Study Design

Using the 2006–2010 National Survey of Family Growth, we fit multivariable-adjusted logistic and Cox regression models to estimate odds ratios and hazard ratios for getting a postpartum or interval sterilization, respectively, according to race/ethnicity and insurance status.

Results

Women’s chances of obtaining a sterilization varied by both race/ethnicity and insurance. Among women with Medicaid, whites were more likely to use female sterilization than African Americans and Latinas. Privately insured whites were more likely to rely on vasectomy than African Americans and Latinas, but among women with Medicaid-paid deliveries reliance on vasectomy was low for all racial/ethnic groups.

Conclusions

Low-income racial/ethnic minority women are less likely to undergo sterilization following delivery compared to low-income whites and privately insured women of similar parities. This could result from unique barriers to obtaining permanent contraception and could expose women to the risk of future unintended pregnancies.

Implications

Low-income minorities are less likely to undergo sterilization than low-income whites and privately insured minorities, which may result from barriers to obtaining permanent contraception, and exposes women to unintended pregnancies.     

Potential unintended pregnancies averted and cost savings associated with a revised Medicaid sterilization policy

Objective

Medicaid sterilization policy, which includes a mandatory 30-day waiting period between consent and the sterilization procedure, poses significant logistical barriers for many women who desire publicly funded sterilization. Our goal was to estimate the number of unintended pregnancies and the associated costs resulting from unfulfilled sterilization requests due to Medicaid policy barriers.

Study Design

We constructed a cost-effectiveness model from the health care payer perspective to determine the incremental cost over a 1-year time horizon of the current Medicaid sterilization policy compared to a hypothetical, revised policy in which women who desire a postpartum sterilization would face significantly reduced barriers. Probability estimates for potential outcomes in the model were based on published sources; costs of Medicaid-funded sterilizations and Medicaid-covered births were based on data from the Medicaid Statistical Information System and The Guttmacher Institute, respectively.

Results

With the implementation of a revised Medicaid sterilization policy, we estimated that the number of fulfilled sterilization requests would increase by 45%, from 53.3% of all women having their sterilization requests fulfilled to 77.5%. Annually, this increase could potentially lead to over 29,000 unintended pregnancies averted and $215 million saved.

Conclusion

A revised Medicaid sterilization policy could potentially honor women’s reproductive decisions, reduce the number of unintended pregnancies and save a significant amount of public funds.

Implication

Compared to the current federal Medicaid sterilization policy, a hypothetical, revised policy that reduces logistical barriers for women who desire publicly funded, postpartum sterilization could potentially avert over 29,000 unintended pregnancies annually and therefore lead to cost savings of $215 million each year.     

The safety,efficacy and acceptability of task sharing tubal sterilization to midlevel providers: a systematic review

Background

Task sharing is an important strategy for increasing access to modern, effective contraception for women and reducing unmet need for family planning.

Objective

The objective was to identify evidence for the safety, efficacy or acceptability of task sharing tubal sterilization to midlevel providers.

Search strategy

We searched PubMed, Cochrane and Popline for articles in all languages using the following key words: task sharing, tubal sterilization, midlevel providers, task shifting.

Selection criteria

All studies reporting on any measure of safety, efficacy or acceptability of tubal sterilization performed by any cadre of midlevel providers.

Data collection and analysis

Data were independently abstracted by two authors and graded using the United States Preventive Services Task Force rating for evidence quality. Heterogeneity of outcome measures precluded a meta-analysis.

Main results

Nine studies of fair to poor quality reported on safety and acceptability outcomes. Generalizability of findings is limited by inadequate sample size and lack of statistical comparisons. No study reported on long-term efficacy outcomes.

Conclusions

Well-designed clinical trials, of adequate sample size, are urgently needed to establish the safety, efficacy and acceptability of task sharing tubal sterilization to midlevel providers.     

“We never thought of a vasectomy”: a qualitative study of men and women's counseling around sterilization

Background

Sterilization is the most commonly used method of contraception in the United States; however, little is known about how providers counsel about these procedures or the information patients desire. In this study, we explore male and female experiences of sterilization counseling and their perspectives on ideal sterilization counseling.

Study design

In-depth individual and group interviews were conducted with 37 heterosexual couples between the ages of 25 and 55 years. Each couple had reached their desired family size. Interviews were recorded and transcribed using NVivo software and analyzed using modified grounded theory.

Results

Men and women differed in their experiences of sterilization counseling. Women commonly received counseling on female sterilization but not vasectomy, while men rarely discussed either form of sterilization with their providers. Both men and women desired more information about sterilization.

Conclusions

Contraceptive counseling of couples who have completed childbearing does not routinely include men or the option of vasectomy, despite the advantages of this method with respect to safety, efficacy and cost. Family planning and primary care providers have an important role in ensuring that couples are aware of all their options and can make an informed decision about their contraception.     

Adherence to hysterosalpingogram appointments following hysteroscopic sterilization among low-income women

Background

The few studies on post-Essure hysterosalpingogram (HSG) adherence rates show inconsistent results. This study examined associations between sociodemographic variables not examined in prior studies and HSG adherence among low-income women.

Study Design

Medical records of 286 women who underwent sterilization between August 31, 2005, and September 30, 2011, were reviewed. chi-Square and Mann–Whitney U tests were used to determine variable associations with HSG adherence.

Results

The adherence rate for the first HSG was 85.0% (243/286). Variables associated with adherence were lower education level (p=.01), not working outside the home (p=.04), being married (p<.0001), lower gravidity (p=.03), fewer lifetime number of sexual partners (p<.0001), no sexually transmitted infection history (p<.01), Hispanic ethnicity (p<.0001), Spanish as a primary language (p<.0001) and living farther from the clinic (p<.01).

Conclusions

This study demonstrates that achieving high rates of adherence with the recommended HSG following Essure placement is feasible among low income populations. Furthermore, not speaking English or having to commute a far distance to the clinic do not appear to be barriers. This is encouraging considering the importance of this test to confirm tubal occlusion.     

Medicaid and fulfillment of desired postpartum sterilization

Objective

We sought to assess fulfillment of sterilization requests while accounting for the complex interplay between insurance, clinical and social factors in a contemporary context that included both inpatient and outpatient postpartum sterilization procedures.

Cancer risk after sterilization with transcervical quinacrine: updated findings from a Chilean cohort

Background

Dating back to the 1970s, thousands of women worldwide have voluntarily been sterilized with transcervical insertion of quinacrine pellets. The safety and efficacy of the technology are still being assessed today; in particular, better estimates on the incidence of human cancers are now feasible.

Methods

We conducted a cohort study of 1492 women in Santiago and Valdivia, Chile, who received transcervical quinacrine pellets for contraceptive sterilization between l977 and l989. We periodically interviewed women with the last interviews in 2006-2007 and reviewed their medical records. We calculated age and site-specific incidence of invasive cancers and compared the observed cases to the number of expected cases based on data from the Cali, Colombia, cancer registry, gathered by the International Agency for Research on Cancer.

Results

During 23,894 person-years of follow-up, 41 invasive cancers were identified, including 16 new cases that had occurred since the previous analysis. Ten cases of cervical cancer were observed, compared with 12.1 expected. Since the initial study's confirmation of a single case of leiomyosarcoma, no other uterine cancers have been diagnosed. We would expect 2.0 uterine cancers during this number of observed women-years. One case of ovarian cancer was diagnosed, compared with 3.1 expected.

Conclusion

Rates of cancer among women exposed to intrauterine quinacrine are similar to population-based rates.     

Contraceptive sterilization use among married men in the United States: results from the male sample of the National Survey of Family Growth

Background

Surgical sterilization has many advantages. Previous information on prevalence and correlates was based on surveys of women.

Study Design

We estimated the prevalence of vasectomy and tubal ligation of partners for male participants in the 2002 National Survey of Family Growth, a nationally representative survey of US residents aged 15-44 years. We identified factors associated with sterilizations using bivariate and multivariate techniques.

Results

The findings revealed that 13.3% of married men reported having had a vasectomy and 13.8% reported tubal sterilization in their partners. Vasectomy increased with older age and greater number of biological children, non-Hispanic white ethnicity, having ever gone to a family planning clinic. Tubal sterilization use was more likely among men who had not attended college, those of older age and those with live births.

Discussion

One in eight married men reported having vasectomies. Men who rely on vasectomies have a somewhat different profile than those whose partners have had tubal sterilizations.     

Contraception after cancer treatment: describing methods,counseling, and unintended pregnancy risk

Objective

The objective was to describe contraceptive methods utilized by young female cancer survivors and determine whether pretreatment fertility counseling decreases unintended pregnancy risk.

Methods

One thousand and forty-one nongynecologic cancer survivors between18 and 40 years of age responded to a survey of reproductive health, contraceptive methods utilized and history of fertility counseling before cancer treatment. Subjects who had resumed menstrual bleeding following treatment and had not undergone surgical sterilization were defined at risk of unintended pregnancy if they reported unprotected vaginal intercourse in the prior month but did not desire conception. Statistical methods utilized were Student’s t test and χ².

Results

Overall, 918 women (88%) received treatment with potential to affect fertility (chemotherapy, radiation or sterilizing surgery). Of 476 women younger than 40 years old who still had menses, 58% did not want to conceive; of these 275 women, 21% reported unprotected intercourse in the prior month and were defined at risk of unintended pregnancy. This compares to the 7.3% risk of unintended pregnancy reported by the National Center for Health Statistics. Increasing age was associated with greater risk of unintended pregnancy (odds ratio 1.07, p=.006). The following contraceptive methods were reported: barrier (25.5%), hormonal (24.5%), tubal ligation (21.3%) vasectomy (17.5%), intrauterine device (7.2%) and other (4.0%). Sixty-seven percent of women received pretreatment fertility counseling. Counseling prior to treatment did not decrease risk of unintended pregnancy (p=.93).

Conclusions

Sexually active cancer survivors are at threefold increased risk of unintended pregnancy compared to the US population. Contraceptive counseling in this high-risk population is recommended posttreatment.

Implications

Sexually active cancer survivors are at considerable risk of unintended pregnancy. Patient report of pretreatment counseling regarding fertility was not associated with a decline in risk of unintended pregnancy, highlighting the importance of clear recommendations regarding content and timing of counseling.     

Detection of two biological markers of intercourse: prostate-specific antigen and Y-chromosomal DNA

Background

Although biological markers of women's exposure to semen from vaginal intercourse have been developed as surrogates for risk of infection or probability of pregnancy, data on their persistence time and clearance are limited.

Study Design

During 2006–2008, 52 couples were enrolled for three 14-day cycles of abstinence from vaginal sex during which women were exposed in the clinic to a specific quantity (10, 100 or 1000 μL) of their partner's semen. Vaginal swabs were collected before and at 1, 6, 12, 24, 48, 72 and 144 h after exposure for testing for prostate-specific antigen (PSA) and Y-chromosome DNA (Yc DNA).

Results

Immediately after exposure to 1000 μL of semen, the predicted sensitivity of being PSA positive was 0.96; this decreased to 0.65, 0.44, 0.21 and 0.07 at 6, 12, 24 and 48 h, respectively. Corresponding predicted sensitivity of being Yc DNA positive was 0.72 immediately postexposure; this increased to 0.76 at 1 h postexposure and then decreased to 0.60 (at 6 h), 0.63 (at 12 h), 0.49 (at 24 h), 0.21 (at 48 h), 0.17 (at 72 h) and 0.12 (at 144 h).

Conclusions

Overall findings suggest that PSA may be more consistent as a marker of very recent exposure and that Yc DNA is more likely to be detected in the vagina after 12 h postexposure compared to PSA.     

Long-term outcomes after elective sterilization procedures — a comparative retrospective cohort study of Medicaid patients

Objectives

The objectives were to compare the long-term outcomes, including hysterectomy, chronic pelvic pain (CPP) and abnormal uterine bleeding (AUB), in women post hysteroscopic sterilization (HS) and laparoscopic tubal ligation (TL) in the Medicaid population.

Unmet demand for highly effective postpartum contraception in Texas

Objectives

We aimed to assess women's contraceptive preferences and use in the first 6 months after delivery. The postpartum period represents a key opportunity for women to learn about and obtain effective contraception, especially since 50% of unintended pregnancies to parous women occur within 2 years of a previous birth.

Methods

We conducted a prospective cohort study of 800 postpartum women recruited from three hospitals in Austin and El Paso, TX. Women aged 18–44 who wanted to delay childbearing for at least 24 months were eligible for the study and completed interviews following delivery and at 3 and 6 months postpartum. Participants were asked about the contraceptive method they were currently using and the method they would prefer to use at 6 months after delivery.

Results

At 6 months postpartum, 13% of women were using an intrauterine device or implant, and 17% were sterilized or had a partner who had had a vasectomy. Twenty-four percent were using hormonal methods, and 45% relied on less effective methods, mainly condoms and withdrawal. Yet 44% reported that they would prefer to be using sterilization, and 34% would prefer to be using long-acting reversible contraception (LARC).

Conclusions

This study shows a considerable preference for LARC and permanent methods at 6 months postpartum. However, there is a marked discordance between women’s method preference and actual use, indicating substantial unmet demand for highly effective methods of contraception.

Implications

In two Texas cities, many more women preferred long-acting and permanent contraceptive methods (LAPM) than were able to access these methods at 6 months postpartum. Women’s contraceptive needs could be better met by counseling about all methods, by reducing cost barriers and by making LAPM available at more sites.     

Levels and determinants of switching following intrauterine device discontinuation in 14 developing countries

Objective

To examine the levels and determinants of switching to any reversible modern contraceptive method following intrauterine device (IUD) discontinuation due to method-related reasons among women in developing countries.

Study Design

We analysed 5-year contraceptive calendar data from 14 Demographic and Health Surveys, conducted in 1993–2008 (n= 218,092 women; 17,151 women contributed a total of 18,485 IUD episodes). Life-table methods were used to determine overall and cause-specific probabilities of IUD discontinuation at 12 months of use. For IUD episodes discontinued due to method-related reasons, the probability of switching to another reversible modern method within 3 months was estimated, overall and by place of residence, education level, motivation for use, age category and wealth tertiles. Country-specific rate ratios (RR) were estimated using generalized linear models, and pooled RRs using meta-analyses.

Results

The median duration of uninterrupted IUD use was 37 months. At 12 months, median probability of discontinuation was 13.2% and median probability of discontinuation due to method-related reasons was 8.9%. Within 3 months of discontinuation due to method-related reasons, half of the women had switched to another reversible modern method, 12% switched to traditional methods, 12% became pregnant, and 25% remained at risk for pregnancy. More educated women were more likely to switch to another reversible modern method than women with primary education or less (pooled RR 1.47; 95% CI 1.10–1.96), as were women in the highest wealth tertile (pooled RR 1.38; 95% CI 1.04–1.83) and women who were limiting births (pooled RR 1.35; 95% CI 1.08–1.68).

Conclusion

Delays to switching and switching to less reliable methods following IUD discontinuation remain a problem, exposing women to the risk of unwanted pregnancy. Family planning programmes should aim to improve quality of services through strengthening of counselling and follow-up services to support women's continuation of effective methods.

Implications

The risk of unintended pregnancy following IUD discontinuation remains high in developing countries. The quality of family planning services may be an important factor in switching to alternative modern contraceptive methods. Service providers should focus on counselling services and follow-up of women to support the continued use of effective methods.     

Correlates of long-acting reversible contraception versus sterilization use in advanced maternal age

Purpose

To identify correlates associated with choosing long-acting reversible contraception (LARC) over female sterilization (FS) from a subsample of women aged 35 to 44 years in a nationally representative survey.

The effect of tubal sterilization through electrocoagulation on the ovarian reserve

Background

The study was conducted to compare the effects of tubal sterilization through electrocoagulation and the application of mechanical clips on the ovarian reserve.

Study Design

Eighty-eight patients in the reproductive period with the desire of tubal sterilization were included in the prospective, randomized study. The patients were divided into two groups by simple randomization as tubal sterilization through electrocoagulation group and the application of mechanical clips group. Day-3 serum follicle stimulating hormone, luteinizing hormone, estradiol, inhibin-B and antimüllerian hormone and Day-3 total ovarian volume measurements and anthral follicle counts of all patients in the preoperative and 10th postoperative months were compared both within and between the two groups.

Results

A significant difference between the postoperative 10th-month Day-3 total ovarian volumes and anthral follicle counts was detected between the electrocoagulation and mechanical clips application groups.

Conclusion

Tubal sterilization by electrocoagulation is very likely to have an adverse effect on the ovarian reserve in the postoperative period.     

The use of a low-literacy version of the Medicaid sterilization consent form to assess sterilization-related knowledge in Spanish-speaking women: results from a randomized controlled trial

Objective

To learn whether a version of the Medicaid Sterilization Consent Form (SCF) adapted for populations of low-literacy can help Spanish-speaking women better understand the process and consequences of tubal sterilization.

Pregnant immigrant Nigerian women: an exploration of dietary intakes

Objective

The aim of the study is to explore the dietary intakes of a prominent ethnic minority group of women from Sub-Saharan Africa during pregnancy, in order to identify nutritional issues of concern which may impact on pregnancy outcomes and whether different food based dietary guidelines may be required to meet their needs.

Study design

This is an observational study with quantitative assessment of nutrient intakes and an exploration of meal composition and food choices.

Methods

Fifty-two Nigerian pregnant women in their second or third trimester of pregnancy were recruited from antenatal clinics in the National Maternity Hospital, Dublin, Ireland. Early pregnancy weight was measured and body mass index recorded. A 24 h dietary recall was used to assess food and nutrient intakes.

Results

Eighty-nine per cent of the study population were classified as overweight or obese. These women appear to be maintaining traditional African dietary habits and have a healthy macronutrient composition in the diet. The intake of key pregnancy micronutrients such as calcium, vitamin D and folate may be insufficient from diet alone to meet requirements and supplements may be inadequately utilized in a timely manner.

Conclusions

These women represent a vulnerable obstetric group that may be at risk of adverse pregnancy outcomes due to high obesity rates and inadequate micronutrient status in early pregnancy. Provision of dietary advice should be tailored to suit their cultural dietary practices and food preferences. Pre-conception counselling on healthy lifestyle and appropriate supplement usage may be beneficial, although larger studies are required to assess the need for specific nutrition policy recommendations.     

Delayed pregnancy testing and second-trimester abortion: can public health interventions assist with earlier detection of unintended pregnancy?

Background

Delayed pregnancy testing has been associated with presentation for abortion in the second trimester. Little is known about acceptability of potential interventions to hasten pregnancy recognition.

Study design

A total of 592 women presenting for abortion at six clinics in the United States completed surveys on contraceptive use, risk behavior, timing of first pregnancy test and interest in interventions to speed pregnancy recognition and testing.

Results

Forty-eight percent of women presenting for second-trimester abortion delayed testing until at least 8 weeks. In multivariate analysis, women who often spotted between periods had higher odds of delaying pregnancy testing [odds ratio (OR) 2.7, 95% confidence interval (CI) 1.04–6.94]. Women who often missed periods had higher odds of second-trimester abortion (OR 2.1, 95% CI 1.34–3.13). The majority (64%) of women were not aware of a fertile time in the menstrual cycle; these women had higher odds of second-trimester abortion (OR 2.0, 95% CI 1.21–3.37). Ninety-four percent of women expressed interest in at least one potential intervention to help recognize pregnancy earlier.

Conclusions

While there was near-universal interest in earlier pregnancy recognition, no single proposed intervention or scenario was endorsed by the majority. Improving sexual health awareness is an important consideration in future efforts to expedite pregnancy testing.

Implications

We found near-universal interest in earlier pregnancy recognition, though no single proposed intervention or scenario garnered majority support. Based on our findings, the concept of improving sexual health awareness through education should be incorporated in the development of future strategies to hasten recognition of unintended pregnancy.
