RESUMO

High rates of unplanned pregnancies persist despite pharmacological developments and advancements in contraceptive methods. Here, we demonstrate that the etonogestrel-releasing subdermal contraceptive implant (IMP-ETN) may be an appropriate and cost-effective alternative to levonorgestrel-releasing intrauterine systems (LNG-IUSs) for women in Brazil. For our pharmacoeconomic analysis, we reviewed the literature on IMP-ETN regarding its acceptance, eligibility criteria, choice, relations with age, adverse events and, finally, the unmet need in the fee-for-service private healthcare sector. We considered qualitative observations in combination with quantitative analysis and performed a deterministic sensitivity analysis to investigate whether this technology can be self-sustainable over a period of five years. The target population for this analysis comprised 158,696 women. Compared with the continued use of LNG-IUSs, adopting the IMP-ETN can result in a cost avoidance of $ 7.640.804,02 in the first year and $ 82,455,254.43 in five years. Disseminating information among physicians will promote this change and strengthen the potential cost avoided by private health system payers. These savings can be used to improve other healthcare programs and strategies. Moreover, the principles of care can be promoted by improving and adapting healthcare systems and expanding treatment and follow-up strategies. This would also provide support to women's reproductive rights and improve their quality of life. Our results suggest that the IMP-ETN has a favorable cost-effectiveness profile. Given all its advantages and negative incremental cost impact over a period of five years, the IMP-ETN may be a more favorable alternative to LNG-IUSs. Therefore, it should be offered to beneficiaries with a private healthcare plan. This analysis overcomes previous barriers to the use of cost-benefit models, and our results may help balance decision-making by policymakers, technical consultants, and researchers.

RESUMO

Injectables are one of the most popular methods of contraception worldwide, particularly in sub-Saharan Africa. An advantage of injectables over shorter-acting methods is that they provide additional flexibility by not requiring re-supply as frequently. However, there is a risk that injectable users may delay their next injection and may therefore have reduced or no protection from pregnancy. In surveys, women may report that they are using contraception in the form of injectables when the time since they had their last injection (more than four months) would imply that they have reduced protection against the risk of pregnancy. We carried out two field studies in urban Malawi, and we record reported injectable contraceptive use while also asking the number of months since women received their last injection. We observe that 13.8 percent of women who report using injectables also report that they received their last injection more than four months ago, and 11 percent report that they received their last injection more than six months ago. Our analysis highlights the need for additional follow-up with women who report using injectables in surveys to confirm whether they are, in fact, using the method effectively.

RESUMO

PURPOSE: To understand contraceptive use patterns (initiation, switching, discontinuation) as well as associations with pregnancy in adolescents and young adults attending a teen family planning clinic. METHODS: We performed a chart review of adolescent and young adult patients (ages 12-20) attending a teen family planning clinic in Atlanta, GA between January 1, 2017, and December 31, 2019. Using a standardized abstraction form with quality controls, we collected available data on contraceptive methods used and pregnancy test results during the 3-year period. We analyzed contraceptive use patterns descriptively. We calculated and compared pregnancy incidence according to different contraceptive switch patterns. RESULTS: Our sample included 2,798 individuals who initiated 2,358 prescribed methods. The most commonly prescribed methods of contraception were the contraceptive injection (28.3%), etonogestrel implant (23.5%) and combined hormonal pill (23.2%). There were 599 discontinuations of prescribed methods; side effects like bleeding and headache were the most cited reasons for discontinuation. Most (75.8%) initiated a moderately or highly effective method after discontinuing a moderately or highly effective method. The incidence rate of pregnancy was highest for those who had discontinued an intrauterine device or implant and started a shorter-acting contraceptive method. DISCUSSION: Employing patient-centered contraceptive counseling that incorporates contraceptive experiences in addition to facts and allows for exploration and change may be valuable for young people. Successful navigation of contraceptive switches may require additional attention, education, and strategy, which could include hypothetical problem solving, close follow-up, and telehealth or virtual care.

RESUMO

Several effective contraceptive options are available for use by adolescents, including the long-acting reversible subdermal implant and intrauterine devices, which provide a high level of convenience, privacy, and effectiveness for an adolescent. Knowledge of all the effective birth control methods is essential for the pediatrician to be able to provide effective contraceptive counseling for an adolescent. An approach to counseling using a reproductive justice framework, which allows the provider and adolescent patient to engage in shared decision-making, is described. This article focuses on the long-acting reversible etonogestrel (ENG) subdermal implant for adolescents. The ENG implant is labeled for preventing pregnancy by suppressing ovulation. The ENG implant may also have a role in ameliorating dysmenorrhea and heavy menstrual bleeding. Postlabeling studies indicate that the ENG implant is effective for up to 5 years, although the device's labeling states effectivenessup to 3 years. The main contraindication to using the ENG implant is pregnancy itself. Safe initiation of the ENG implant is described, including an approach to determine whether an adolescent is pregnant. The main adverse effect of the ENG implant is an unpredictable bleeding pattern that is most often ameliorated by use of nonsteroidal anti-inflammatory medications, as well as estrogen, if not contraindicated for the patient. Details of the insertion and removal procedures, including potential complications, are described to enable the pediatrician to provide effective anticipatory guidance for the adolescent.

RESUMO

The intrauterine device is one of the most effective forms of contraception. Use of the intrauterine device has increased in the United States over the last 2 decades. Two formulations are commercially available in the United States: the levonorgestrel-releasing intrauterine device and the copper intrauterine device. The levonorgestrel intrauterine device releases progestin, causing endometrial suppression and cervical mucus thickening, whereas the primary mechanism of action of the copper intrauterine device is to create a local inflammatory response to prevent fertilization. Whereas the protective effects of combined hormonal contraception against ovarian and endometrial cancer, and of tubal sterilization against ovarian cancer are generally accepted, less is known about the effects of modern intrauterine devices on the development of gynecologic malignancies. The best evidence for a protective effect of intrauterine device use against cancer incidence pertains to levonorgestrel intrauterine devices and endometrial cancer, although studies suggest that both copper intrauterine devices and levonorgestrel intrauterine devices reduce endometrial cancer risk. This is supported by the proposed dual mechanisms of action including both endometrial suppression and a local inflammatory response. Studies on the relationship between intrauterine device use and ovarian cancer risk show conflicting results, although most data suggest reduced risk of ovarian cancer in intrauterine device users. The proposed biological mechanisms of ovarian cancer reduction (foreign-body inflammatory response, increased pH, antiestrogenic effect, ovulation suppression) vary by type of intrauterine device. Whereas it has been well established that use of copper intrauterine devices confers a lower risk of cervical intraepithelial neoplasms, the effect of levonorgestrel intrauterine device use on cervical cancer remains unclear. Older studies have linked its use to a higher incidence of cervical dysplasia, but more recent literature has found a decrease in cervical cancer with intrauterine device use. Various mechanisms of protection are postulated, including device-related inflammatory response in the endocervical canal and prostaglandin-mediated immunosurveillance. Overall, the available evidence suggests that both levonorgestrel intrauterine devices and copper intrauterine devices reduce gynecologic cancer risk. Whereas there is support for the reduction of endometrial cancer risk with hormonal and copper intrauterine device use, and reduction of cervical cancer risk with copper intrauterine device use, evidence in support of risk reduction with levonorgestrel intrauterine device use for cervical and ovarian cancers is less consistent.

RESUMO

BACKGROUND: Cervical dysgenesis is categorized into cervical fragmentation, cervical fibrous cord, and cervical obstruction. The definitive management for cervical dysgenesis is either uterovaginal anastomosis (UVA) or hysterectomy. OBJECTIVE: To compare the prevalence of dysmenorrhea, hematometra, and need for dilatation after UVA with and without postprocedural placement of a levonorgestrel intrauterine system (LNG-IUS). METHODS: This was a retrospective cohort study in which 14 patients with cervical dysgenesis were included. Patients had undergone UVA between May 2015 and January 2022 at the Department of Obstetrics and Gynecology of the Cairo University Teaching Hospital. Six patients who had an LNG-IUS inserted after UVA were included in group A, and 8 patients who had undergone UVA without LNG-IUS insertion were included in group B. Transabdominal and/or transvaginal ultrasound was performed monthly for the first 3 months after LNG-IUS insertion in group A and after UVA in group B. Thereafter, the patients were followed up every 6 months. The primary outcomes were dysmenorrhea, hematometra, and need for dilatation of the anastomosis site. RESULTS: The number of patients who developed hematometra was significantly lower in group A than in group B (0 [0%] vs 6 [75%], P = .01). The number of patients who required dilatation was significantly lower in group A than in group B (0 [0%] vs 6 [75%], P = .01). There was no significant difference in the incidence of dysmenorrhea between the 2 groups. CONCLUSION: We recommend offering LNG-IUS after UVA for adolescents who present with cervical dysgenesis. LNG-IUS decreases the recurrence of hematometra and subsequent surgical interventions.

RESUMO

INTRODUCTION: Adolescent females with developmental delays (DDs) experience unique physical and emotional challenges related to menstruation. Providers often recommend hormonal medication for menstrual management. The objective of our study was to describe the utilization and safety of the levonorgestrel-releasing intrauterine system (LNG-IUS) in adolescents with DDs. METHODS: We utilized the Pediatric Health Information System to identify females aged 10-25 with DDs who underwent an LNG-IUS insertion between 2011 and 2020. Using a gynecologic procedure and diagnosis codes, we assessed indications for and complications of LNG-IUS use. We also evaluated early LNG-IUS removal. RESULTS: One thousand five hundred and sixty female patients with DDs underwent LNG-IUS insertion. LNG-IUS insertion under anesthesia was most commonly performed in patients with autism and Down syndrome, and unspecified menstrual issues were documented for 40% of the cohort. Perforation was observed in 11 patients (1%), and mechanical complications (malpositioned IUS or lost threads) were observed in 23 patients (1%). DISCUSSION: This is the largest analysis of LNG-IUS use in patients with DDs to our knowledge and shows the utilization of LNG-IUS in patients with DDs. We provide descriptive information that providers can use to accurately advise their patients with DDs on the risks and benefits of LNG-IUS use for menstrual management.

RESUMO

BACKGROUND: Initiating a progestin-based contraceptive before the drop in progesterone required to start lactogenesis stage II could theoretically affect lactation. Previous studies have shown that initiating progestin-based contraception in the postnatal period before birth-hospitalization discharge has no detrimental effects on breastfeeding initiation or continuation compared with outpatient interval initiation. However, there are currently no breastfeeding data on the impact of initiating the etonogestrel contraceptive implant in the early postnatal period immediately in the delivery room. OBJECTIVE: This study examined the effect of delivery room vs delayed birth-hospitalization contraceptive etonogestrel implant insertion on breastfeeding outcomes. STUDY DESIGN: This was a noninferiority randomized controlled trial to determine if time to lactogenesis stage II (initiation of copious milk secretion) differs by timing of etonogestrel implant insertion during the birth-hospitalization. We randomly assigned pregnant people to insertion at 0 to 2 hours (delivery room) vs 24 to 48 hours (delayed) postdelivery. Participants intended to breastfeed, desired a contraceptive implant for postpartum contraception, were fluent in English or Spanish, and had no allergy or contraindication to the etonogestrel implant. We collected demographic information and breastfeeding intentions at enrollment. Onset of lactogenesis stage II was assessed daily using a validated tool. The noninferiority margin for the mean difference in time to lactogenesis stage II was defined as 12 hours in a per-protocol analysis. Additional electronic surveys collected data on breastfeeding and contraceptive continuation at 2 and 4 weeks, and 3, 6, and 12 months. RESULTS: We enrolled and randomized 95 participants; 77 participants were included in the modified intention-to-treat analysis (n=38 in the delivery room group and n=39 in the delayed group) after excluding 18 because of withdrawing consent, changing contraceptive or breastfeeding plans, or failing to provide primary outcome data. A total of 69 participants were included in the as-treated analysis (n=35 delivery room, n=34 delayed); 8 participants who received the etonogestrel implant outside the protocol windows were excluded, and 2 participants from the delivery room group received the etonogestrel implant at 24 to 48 hours and were analyzed with the delayed group. Participants were similar between groups in age, gestational age, and previous breastfeeding experience. Delivery room insertion was noninferior to delayed birth-hospitalization insertion in time to lactogenesis stage II (delivery room [mean±standard deviation], 65±25 hours; delayed, 73±61 hours; mean difference, -9 hours; 95% confidence interval, -27 to 10). Onset of lactogenesis stage II by postpartum day 3 was not significantly different between the groups. Lactation failure occurred in 5.5% (n=2) participants in the delayed group. Ongoing breastfeeding rates did not differ between the groups, with decreasing rates of any/exclusive breastfeeding over the first postpartum year. Most people continued to use the implant at 12 months, which did not differ by group. CONCLUSION: Delivery room insertion of the contraceptive etonogestrel implant does not delay the onset of lactogenesis when compared with initiation later in the birth-hospitalization and therefore should be offered routinely as part of person-centered postpartum contraceptive counseling, regardless of breastfeeding intentions.

RESUMO

OBJECTIVES: To monitor pregnancy occurrence and outcomes among Nexplanon users in the United States during standard clinical practice. STUDY DESIGN: The Nexplanon Observational Risk Assessment (NORA) study was a large prospective cohort study conducted in the United States (US). Study participants with a newly inserted Nexplanon implant were recruited by health care professionals (HCPs) who had completed the Nexplanon clinical training. Via a survey, study participants were followed up at 6-month intervals for 36 months and 6 months after implant removal. Reported unintended pregnancies were validated and classified as noninsertion, preinsertion, during-use, or postremoval. RESULTS: Four hundred and twenty-eight HCPs in 47 states recruited 7364 Nexplanon users. Pregnancies included one noninsertion, eight preinsertion, three during-use, and 14 postremoval pregnancies; of these 26 pregnancies, 22 resulted in the birth of a healthy child, two resulted in an induced abortion, one resulted in a spontaneous abortion, and one resulted in an ectopic pregnancy. Six pregnancies occurred during-use (n = 3) or within 7 days following implant removal (n = 3), yielding a Pearl Index of 0.04 (95% CI, 0.02-0.09). CONCLUSIONS: Nexplanon is an effective contraceptive in real-world users; the Pearl Index was 0.02 (95% CI, 0.00-0.06) for during-use pregnancies, and 0.04 when including pregnancies that occurred within 7 days following implant removal. IMPLICATIONS: This large real-world-use study indicates that Nexplanon is as effective as shown in the preapproval clinical trials.

RESUMO

BACKGROUND: The number of women using long-acting reversible contraception (LARC)-intrauterine devices (IUDs) and implants-is increasing and 14% of contraceptive users in the United States adopt LARC. We examined correlates of LARC never-use in a population-based survey of reproductive-aged women in Ohio. METHODS: We analyzed data from the 2018-19 Ohio Survey of Women. We examined the prevalence of LARC never-use and reasons for never-use among ever users of contraception (N = 2388). Using Poisson regression to generate prevalence ratios (PRs), we examined associations between selected correlates (demographic factors, healthcare access/quality measures, and religious/political views) and LARC never-use. RESULTS: Most Ohio women (74%) had never used LARC. Commonly reported reasons for not using an IUD or an implant were preferring a different method (46% and 45%, respectively), not wanting an object inside their body (45% and 43%), side effect concerns (39% and 33%), insertion/removal concerns (31% and 25%), and unfamiliarity (13% and 20%). Conservative political views (PR: 1.12, 95% confidence interval [CI]: 1.04-1.22), pro-life affiliation (PR: 1.11, 95% CI: 1.02-1.20), placing high importance on religion in daily life (PR: 1.15, 95% CI: 1.06-1.26), and being non-Hispanic white as compared to non-Hispanic Black (PR: 1.20, 95% CI: 1.02-1.41) were significantly associated with LARC never-use. Findings were generally similar for models analyzing IUD and implant never-use separately. CONCLUSIONS: Among ever-users of contraception, LARC never-use was associated with having conservative political views, being religious, and having a pro-life affiliation. Except for race/ethnicity, demographic and healthcare measures were not associated with LARC never-use among women in Ohio.

RESUMO

BACKGROUND: Although long-acting contraceptive methods are highly effective, safe, and provide uninterrupted protection from unintended pregnancy compared to short-acting methods, evidences suggest that majority of women were relayed on short-acting contraceptive methods. Thus, this study aimed to determine the level of long-acting contraceptive methods utilization and associated factors among married women in Farta Woreda, Northwest Ethiopia, 2021. METHODS: A community-based cross-sectional study supplemented with qualitative data was performed among 556 married women from March 1 to 31, 2021. A semi-structured interviewer-administered questionnaire and interview guides were used to collect the data. The data were entered into Epi data version 4.6 and analyzed by SPSS version 23 software. The association between variables was analyzed using bivariate and multivariable binary logistic regression. The level of statistically significant association was determined at a P-value < 0.05. After translation and transcription, manual thematic analysis was applied to the qualitative data. RESULTS: The magnitude of long-acting contraceptive methods among married women in Farta Woreda was found to be 14.3% [95% CI 11.5-17.6]. Previous use of long-acting contraceptive methods (AOR = 5.83, 95% CI 3.03, 11.21), positive attitude towards long-acting contraceptives (AOR = 2.74, 95% CI 1.48, 5.07), having formal education for husbands' (AOR = 3.05, 95% CI 1.5, 6.21), and poor wealth index (AOR = 3.39, 95% CI 1.33, 8.67) were positively associated with utilization of long-acting contraceptive methods. Moreover, fear of side effects, misconceptions, and partner opposition were the most commonly identified barriers by the qualitative data. CONCLUSION: Utilization of long-acting contraceptives among married women in Farta Woreda was low as compared to the 2020/21 national reproductive health strategy plan to increase the long-acting reversible and permanent contraceptive methods use to 50%. Previous use of long-acting contraceptives, positive attitude towards long-acting contraceptives, husband education, and household wealth index was found to be significantly associated with long-acting contraceptive utilization. Hence, it is better to work more on changing women's attitudes and increasing husband education.


Long-acting contraceptive methods (LACM) are methods used to prevent pregnancy for a longer period than short-acting methods. LACM are classified in two categories, reversible and non-reversible (permanent).This study use a community-based quantitative cross-sectional study supplemented with qualitative data among married women from March 1 to 31, 2021 in Farta Woreda northwest Ethiopia. The association between variables was analyzed using bivariate and multivariable binary logistic regression. Statistically significant association was declared at a P-value < 0.05. For the qualitative data, a thematic analysis was made manually.The current study found that the magnitude of long-acting contraceptive methods among married women in Farta Woreda was 14.3% 95% CI [11.5­17.6]. Women's husband education, wealth index, previous use LACM, and attitude were significantly associated with long-acting contraceptive utilization. Besides, fear of side effects and partner opposition were the most common barriers of LACM.This study report that utilization of long-acting contraceptives among married women in Farta Woreda was significantly low as compared to the national reproductive health strategy 2020/21 plan. Therefore, establishing strategies and polices to change women's attitudes and increasing husband education will be essential when designing implementation plans to scale up uptake of LACM.

RESUMO

SUMMARY: The purpose of this document is to review currently available management options, general principles, and counseling approaches for reproductive-aged patients requesting menstrual suppression. It includes considerations for unique populations, including adolescents, patients with physical or cognitive disabilities or both, and those with limited access to health care. Gynecologists should be familiar with the use of hormonal therapy for menstrual suppression (including combined oral contraceptive pills, combined hormonal patches, vaginal rings, progestin-only pills, depot medroxyprogesterone acetate, the levonorgestrel-releasing intrauterine device, and the etonogestrel implant). Approaches to counseling should be individualized based on patient preferences and goals, average treatment effectiveness, and contraindications or risk factors for adverse events. Counseling regarding the choice of hormonal medication for menstrual suppression should be approached with the utmost respect for patient autonomy and be free of coercion. Complete amenorrhea may be difficult to achieve; thus, obstetrician-gynecologists and other clinicians should counsel patients and caregivers, if applicable, about realistic expectations.

RESUMO

Long-acting reversible contraceptive (LARC) methods are effective options for pregnancy prevention. Currently available products in the United States include an etonogestrel implant, a copper intrauterine device (IUD), and several levonorgestrel IUDs. With increasing prevalence and duration of use, our understanding of efficacy, risks, and benefits has evolved. In addition to a brief discussion on nomenclature and LARC use within a framework of bodily autonomy and reproductive justice, this review covers clinical challenges with placement and removal, evidence-based duration of use, and how to mitigate side effects. Although all obstetrician-gynecologists as well as primary care clinicians can safely provide LARCs, complex family planning specialists are an expert referral source for challenging cases and evidence-based care as contraceptive technology continues to develop.

RESUMO

In brief: The many side effects of current contraceptives leave a large proportion of women without adequate protection. This study shows that zinc, a highly physiologically compatible metal, provides effective long-acting reversible contraception in rats, without requiring the use of hormones. Abstract: Long-acting and reversible contraceptives (LARC) are the most widely used form of female contraception worldwide; however, they have significant side effects that often result in early removal. Most LARCs are hormonal, but the use of exogenous hormones is not suitable for all women and causes side effects in many others. The copper IUD (CuIUD) is the only non-hormonal LARC, but a large proportion of users suffer severe side effects. This study proposes the use of zinc as a suitable alternative to the CuIUD. A rat intrauterine device (IUD) model was established to test the efficacy of a zinc IUD (ZnIUD) against a CuIUD. The IUD was surgically implanted into one uterine horn while the other remained untreated. Both the ZnIUD and CuIUD resulted in zero implantation sites which were significantly fewer compared to non-treated horns. Histological assessment revealed damage and inflammation in the endometrium of CuIUD-treated horns but only minor epithelial changes in ZnIUD-treated horns. This suggests ZnIUDs may not share the side effect profile of the CuIUD. To test the long-term efficacy of the ZnIUD, rats had a ZnIUD surgically implanted into both horns and cohoused with males for 3 months. These rats mated regularly but did not get pregnant, confirming long-term effectiveness. Reversibility of the ZnIUD was also established, as removal of the ZnIUD after 3 months resulted in no significant difference in the number of implantation sites between treated and untreated horns. This study demonstrated the contraceptive efficacy of zinc and its potential as a LARC.

RESUMO

BACKGROUND: Out-of-pocket costs continue to be a barrier to accessing necessary healthcare services, including contraception. We explored how eliminating out-of-pocket cost affects contraceptive method choice among people reporting difficulty paying for healthcare in the previous year, and whether method satisfaction differed by method choice. METHODS: We used data from the HER Salt Lake Contraceptive Initiative. This prospective cohort study provided participants with no-cost contraception (April 2016-March 2017) following a control period that provided no reduction in cost for the contraceptive implant, a reduced price for the hormonal IUD, and a sliding scale that decreased to no-cost for the copper IUD (September 2015-March 2016). We restricted the study population to those who reported difficulty paying for healthcare in the past 12 months. For our primary outcome assessing changes in method selection between intervention and control periods, we ran simultaneous multivariable logistic regression models for each method, applying test corrections for multiple comparisons. Among participants who continued their method for 1 year, we explored differences in method satisfaction using multivariable logistic regression. RESULTS: Of the 1,029 participants reporting difficulty paying for healthcare and controlling for other factors, participants more frequently selected the implant (aOR 6.0, 95% CI 2.7, 13.2) and the hormonal IUD (aOR 3.2, 95% CI 1.7, 5.9) during the intervention than control period. Comparing the same periods, participants less frequently chose the injection (aOR 0.5, 95% CI 0.3, 0.8) and the pill (aOR 0.4, 95% CI 0.3, 0.6). We did not observe a difference in uptake of the copper IUD (aOR 2.0, 95% CI 1.0, 4.1).Contraceptive satisfaction scores differed minimally by contraceptive method used among contraceptive continuers (n = 534). Those who selected LNG IUDs were less likely to report low satisfaction with their method (aOR 0.5, 95% CI 0.3, 0.97). CONCLUSION: With costs removed, participants who reported difficulty paying for healthcare were more likely to select hormonal IUDs and implants and less likely to select the injectable or contraceptive pills. Among continuers, there were few differences in method satisfaction. CLINICALTRIALS: gov Identifier NCT02734199.

RESUMO

BACKGROUND: Over time, demographic and health survey (DHS) data remain valuable to examine variables relating to nationally representative population outcomes for low- and middle-income countries. In Tanzania, there are very limited DHS-based studies on the uptake of Modern Contraceptive Use (MCU). Present studies have focused on measurements at the level of individuals, yet research has shown that MCU variations exists at other levels within populations. In this study, we use a variance component modelling approach to explore variation in MCU at primary sampling unit (PSU) and regional levels while considering survey sample weights. METHODS: Using DHS data from 2016-2017 in Tanzania, we study different variance structures and the respective variation on MCU in a sample of 5263 Women of Reproductive Age (WRA) defined as between the ages of 15-49 years. First, a single variance component was used, followed by its extension to a random coefficient model and we tracked changes in the models. RESULTS: There was an influence of random variations on MCU on the levels of populations much explained by PSU-level clustering than region. On the fixed part, age of a woman, husband education level, desire to have children, and exposure to media and wealth tertiles were important determinants for MCU. Compared to WRA in 15-19 years, the odds of MCU among middle aged women (20-29 and 30-39 years) were 1.94 (95%CI:1.244-3.024) and 2.28 (95%CI:1.372-3.803). Also, increases in media exposure and middle and rich wealth tertiles women led to higher odds for MCU. We also found the presence of random effects influence of wealth tertiles levels on MCU. CONCLUSION: This study highlighted the utility of accounting for variance structures in addressing determinants of MCU while using DHS national level data. Apart from MCU, the DHS data have been widely applied to examine other variables pertaining to public health issues. This approach could be considered a better modelling technique for the DHS studies compared to traditional survey approaches, and to guide hierarchical population-based interventions to increase MCU.

RESUMO

PURPOSE: Long-acting reversible contraceptives (LARC), such as intrauterine devices (IUD) and implants, are highly effective. However, the uptake of LARC in Australia has been slow and the oral contraceptive pill (OC) remains the best known and most widely used contraceptive. Our aim was to investigate women's preferences for the features of LARC. METHODS: We used a discrete choice experiment (DCE) in which each respondent completed 12 choice tasks. We recruited a general population sample of 621 women in Australia aged 18-49 using an online survey panel. A mixed logit model was used to analyse DCE responses; a latent class model explored preference heterogeneity. RESULTS: Overall, 391 (63%) of women were currently using contraception; 49.3% were using an OC. About 22% of women were using a LARC. Women prefer products that are more effective in preventing pregnancy, have low levels of adverse events (including negative effects on mood), and which their general practitioner (GP) recommends or says is suitable for them. CONCLUSIONS: Women have strong preferences for contraceptive products that are effective, safe, and recommended by their GP. The results indicate which characteristics of LARCs need to be front and centre in information material and in discussions between women and healthcare professionals.

RESUMO

BACKGROUND: It is estimated that between 12 to 25% of women who undergo an endometrial ablation for heavy menstrual bleeding (HMB) are dissatisfied after two years because of recurrent menstrual bleeding and/or cyclical pelvic pain, with around 15% of these women ultimately having a hysterectomy. The insertion of a levonorgestrel-releasing intrauterine system (LNG-IUS) immediately after endometrial ablation may inactivate residual untreated endometrium and/or inhibit the regeneration of endometrial tissue. Furthermore, the LNG-IUS may prevent agglutination of the uterine walls preventing intrauterine adhesion formation associated with endometrial ablation. In these ways, insertion of an LNG-IUS immediately after endometrial ablation might prevent subsequent hysterectomies because of persisting uterine bleeding and cyclical pelvic pain or pain that arises de novo. Hence, we evaluate if the combination of endometrial ablation and an LNG-IUS is superior to endometrial ablation alone in terms of reducing subsequent rates of hysterectomy at two years following the initial ablative procedure. METHODS/DESIGN: We perform a multicentre randomised controlled trial in 35 hospitals in the Netherlands. Women with heavy menstrual bleeding, who opt for treatment with endometrial ablation and without contraindication for an LNG-IUS are eligible. After informed consent, participants are randomly allocated to either endometrial ablation plus LNG-IUS or endometrial ablation alone. The primary outcome is the hysterectomy rate at 24 months following endometrial ablation. Secondary outcomes include women's satisfaction, reinterventions, complications, side effects, menstrual bleeding patterns, quality of life, societal costs. DISCUSSION: The results of this study will help clinicians inform women with HMB who opt for treatment with endometrial ablation about whether concomitant use of the LNG-IUS is beneficial for reducing the need for hysterectomy due to ongoing bleeding and/or pain symptoms.

RESUMO

INTRODUCTION: Endometrial hyperplasia is associated with varying risk of endometrial cancer. The aim of this review is to assess effectiveness of levonorgestrel-releasing intrauterine system (LNG-IUS), compared to systemic progestins, in management of endometrial hyperplasia MATERIALS AND METHODS: A search on studies comparing LNG-IUS to systemic progestins was conducted on Scopus, Web of science, Cochrane, PubMed and Embase databases, from the date of inception to September 20th, 2020. Studies were excluded if they were non-comparative, animal studies, review articles, case reports, case series, and conference papers. Primary outcomes include resolution/regression rate, failure rate, and hysterectomy rate. Analysis was pooled using random effect model and was expressed as pooled odds ratios (OR) and 95% confidence interval (CI). Quality assessment was performed using Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale (NOS) assessment tool. MOGGE Meta-analysis Matrix was used to illustrate multiple subgroup analyses. RESULTS: Out of 341 studies retrieved from literature search, 12 were eligible. LNG-IUS yielded significantly higher resolution/regression rate (91.3% vs 68.6%, OR 3.42, 95% CI 1.86-6.30). Failure and hysterectomy rates were significantly lower in LNG-IUS group compared to systemic progestins' group (19.2% vs. 32.3%, OR 0.34, 95% CI 0.20-0.57 and 9.3% vs. 24.1%, OR 0.41, 95% CI 0.29-0.57, respectively). Subgroup analysis of studies including complex hyperplasia only did not show significant difference in resolution/regression rate was not statistically significant. CONCLUSION: LNG-IUS is associated with high success rate in management of women with endometrial hyperplasia. However, specific effectiveness of LNG-IUS on more advanced histologic subtypes is less studied.
