Estimated disability-adjusted life years averted by long-term provision of long acting contraceptive methods in a Brazilian clinic

Etonogestrel-releasing subdermal contraceptive implant: Budget impact analysis based on the Brazilian private healthcare system

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.

A meta-analysis into the mediatory effects of family planning utilization on complications of pregnancy in women of reproductive age

BACKGROUND

Despite conflicting findings in the current literature regarding the correlation between contraceptives and maternal health consequences, statistical analyses indicate that family planning may decrease the occurrence of such outcomes. Consequently, it is crucial to assess the capability of family planning to mitigate adverse maternal health outcomes.

OBJECTIVES

This review investigates the effects of modern contraceptive use on maternal health.

SEARCH METHODS

This systematic review is registered on Prospero (CRD42022332783). We searched numerous databases with an upper date limit of February 2022 and no geographical boundaries.

SELECTION CRITERIA

We included observational studies, including cross-sectional, cohort, case-control studies, and non-RCT with a comparison group. We excluded systematic reviews, scoping reviews, narrative reviews, and meta-analyses from the body of this review.

MAIN RESULTS

The review included nineteen studies, with five studies reporting a reduction in maternal mortality linked to increased access to family planning resources and contraceptive use. Another three studies examined the impact of contraception on the risk of preeclampsia and our analysis found that preeclampsia risk was lower by approximately 6% among contraceptive users (95% CI 0.82-1.13) compared to non-users. Two studies assessed the effect of hormonal contraceptives on postpartum glucose tolerance and found that low-androgen contraception was associated with a reduced risk of gestational diabetes (OR 0.84, 95% CI 0.58-1.22), while DMPA injection was possibly linked to a higher risk of falling glucose status postpartum (OR 1.42, 95% CI 0.85-2.36). Two studies evaluated high-risk pregnancies and births in contraceptive users versus non-users, with the risk ratio being 30% lower among contraceptive users of any form (95% CI 0.61, 0.80). None of these results were statistically significant except the latter. In terms of adverse maternal health outcomes, certain contraceptives were found to be associated with ectopic pregnancy and pregnancy-related venous thromboembolism through additional analysis.

Acceptability and continuation of use of the subdermal contraceptive implant among adolescents and young women in Argentina: a retrospective cohort study

A new public policy was instituted in Argentina for free distribution of subdermal contraceptive implants to women aged 15-24 years old in the public healthcare system. The objective of this study is to determine the extent to which this population adhered to the implant, as well as predictors of continuation. The retrospective cohort study was based on a telephone survey of a random sample of 1101 Ministry of Health-registered implant users concerning the continuation of use, satisfaction with the method and side-effects, and reasons for removal. Descriptive statistics and multivariate regression analysis were used to explore the association between adherence and having received contraceptive counselling, satisfaction, and side effects. We found high levels of adherence (87%) and satisfaction (94%). Common reported side effects were amenorrhoea or infrequent bleeding, perceived weight gain, increased menstrual bleeding and headaches. Multivariate regression analysis indicates that, among adolescents, having received contraceptive counselling increased comfort, while frequent bleeding at six months hindered trust. Participants who had a history of a prior delivery or who had themselves primarily chosen the method were less likely to request the removal of the implant. Our results support the public policy of free implant distribution in the public health sector. This is a sustainable public policy that contributes to equity and access to effective contraception. It is appropriate for adolescents and young women and will also reduce unintended pregnancies. Our results suggest that counselling patients is key prior to insertion of the implant, as it improves acceptability and continuation.

How Much Do Side Effects Contribute to Discontinuation? A Longitudinal Study of IUD and Implant Users in Senegal

Introduction

In Senegal, discontinuation due to sides effects of long-acting, reversible contraceptives (LARCs) is relatively low; 5% of new implant acceptors and 11% of new IUD acceptors stop using in their first year because of health or side effect concerns. This study investigated factors associated with LARC discontinuation in the first 12 months of use in Senegal and explored how LARC users cope with side effects.

Methods

This mixed-method study involved quantitative interviews at five time points with LARC acceptors recruited from three service channels between February 2018 and March 2019. Qualitative interviews were conducted in August 2018 with a subset of those who experienced side effects. Logistic regression models identified factors associated with discontinuation due to side effects and discontinuation for any reason. Twelve-month discontinuation rates due to side effects were also estimated using a cumulative incidence function (CIF) approach to account for time to discontinuation.

Results

In logistic models, method choice (IUD or implant) [OR = 3.15 (95% CI: 1.91–5.22)] and parity [OR = 0.81 (95% CI: 0.7–0.94)] were associated with discontinuation due to side effects; IUD users and women with fewer children were more likely to discontinue. Results for all-cause discontinuation were similar: method choice [OR = 2.39 (95% CI: 1.6–3.58)] and parity [OR = 0.86 (95% CI: 0.77–0.96)] were significant predictors. The 12-month side effect CIF discontinuation rate was 11.2% (95% CI: 7.9–15.0%) for IUDs and 4.9% (95% CI: 3.5–6.6%) for implants. Side effect experiences varied, but most women considered menstrual changes the least acceptable. No statistically significant differences across services channels were observed.

Conclusions

In this study in Senegal, the choice between implants and IUDs had a significant impact on continuation, and women with more children continued LARC methods longer, despite side effects.

High impact health service interventions for attainment of UHC in Africa: A systematic review

African countries have prioritized the attainment of targets relating to Universal Health Coverage (UHC), Health Security (HSE) and Coverage of Health Determinants (CHD)to attain their health goals. Given resource constraints, it is important to prioritize implementation of health service interventions with the highest impact. This is important to be identified across age cohorts and public health functions of health promotion, disease prevention, diagnostics, curative, rehabilitative and palliative interventions. We therefore explored the published evidence on the effectiveness of existing health service interventions addressing the diseases and conditions of concern in the Africa Region, for each age cohort and the public health functions. Six public health and economic evaluation databases, reports and grey literature were searched. A total of 151 studies and 357 interventions were identified across different health program areas, public health functions and age cohorts. Of the studies, most were carried out in the African region (43.5%), on communicable diseases (50.6%), and non-communicable diseases (36.4%). Majority of interventions are domiciled in the health promotion, disease prevention and curative functions, covering all age cohorts though the elderly cohort was least represented. Neonatal and communicable conditions dominated disease burden in the early years of life and non-communicable conditions in the later years. A menu of health interventions that are most effective at averting disease and conditions of concern across life course in the African region is therefore consolidated. These represent a comprehensive evidence-based set of interventions for prioritization by decision makers to attain desired health goals. At a country level, we also identify principles for identifying priority interventions, being the targeting of higher implementation coverage of existing interventions, combining interventions across all the public health functions-not focusing on a few functions, provision of subsidies or free interventions and prioritizing early identification of high-risk populations and communities represent these principles.

A multicenter randomized clinical trial of etonogestrel and levonorgestrel contraceptive implants with nonrandomized copper intrauterine device controls: effect on weight variations up to 3 years after placement

OBJECTIVES

To evaluate weight changes in women randomized to either the etonogestrel (ENG)- or the levonorgestrel (LNG)-releasing contraceptive implants and to compare with users of the TCu380A intrauterine device (IUD).

STUDY DESIGN

A multicenter randomized trial with 1:1 allocation ratio of the ENG and the LNG implants with nonrandomized, age-matched control group of women choosing TCu380A IUD. The primary objective was to assess contraceptive efficacy and method continuation rates and, secondarily, the incidence of common complaints and side effects (including weight changes) associated with use of the three contraceptives. All women were enrolled in nine centers at seven countries. Weight change was evaluated from time at device(s) placement. Confounders were sociodemographic, baseline weight and body mass index, center and time from insertion. We used a linear mixed-effects regression modeling with random intercept and slope. Weight was compared between the two implants groups and between the implants and the IUD groups through linear mixed multivariable regression model.

RESULTS

A total of 995, 997 and 971 users in the ENG implant, LNG implant and IUD groups, respectively, were included. At 36 months of use, ENG and LNG implant users had similar significant mean weight increase of 3.0 kg [95% confidence interval (CI) 2.5-3.5] and 2.9 kg (95% CI 2.4-3.4), respectively (p<.0001), while IUD users had an increase of 1.1 kg (95% CI 0.5-1.7) (p=.0003). On adding the group-time interaction term to the stratified baseline weight models, implant users gained 0.759 kg (standard error [SE] .11) and 0.787 kg (SE .22) more weight than their IUD-user counterparts per year since placement if their baseline weight was in the category 51-69 kg (p<.0001) or ≥70 kg (p=.0005), respectively.

CONCLUSIONS

ENG and LNG implant as well as IUD users had a small but significant weight increase with little clinical significance during the 3 years of follow-up, and it was slightly higher among implant than IUD users weighing >50 kg.

IMPLICATIONS

These findings must be useful for clinicians to counsel implant users which could improve method continuation.

The use of long-acting reversible contraceptives in Latin America and the Caribbean: current landscape and recommendations

STUDY QUESTION

Can the high rate and associated burden of unintended pregnancy (UP) and adolescent pregnancy in Latin America and the Caribbean (LAC) be reduced through wider access to and use of long-acting reversible contraceptive (LARC) methods?

SUMMARY ANSWER

Studies show that impoved access to and use of LARC methods is an effective tool for reducing the high rates of UP, unsafe abortion and abortion-related complications, and maternal deaths (as well as reducing their social and financial burden), and we have provided recommendations to help achieve this in LAC.

WHAT IS KNOWN ALREADY

LAC comprises 46 countries with 650 million inhabitants, and shows large disparities in socioeconomic development, access to health services and attention to sexual and reproductive health rights. The exercise of these rights and universal access to sexual and reproductive health (SRH) programmes is a key strategy for improving maternal health by reducing the number of UPs, the rate of women's and child mortality and morbidity, and the number of unsafe abortions. The implementation of SRH programmes in the region has contributed to a decrease in pregnancy rates of more than 50% over 40 years. However, despite this progress, the numbers of UP and adolescent pregnancies are still among the highest worldwide, which can be attributed in large part to the low prevalence of use of LARC methods.

STUDY DESIGN SIZE DURATION

This is a position paper with the objective of reviewing the magnitude and burden of UP in LAC, as well as available LARC methods and barriers to their access, with the goal of increasing knowledge and awareness among healthcare professionals (HCP), policymakers and the general public about the potential to reduce UP rates through the increased use of LARC.

PARTICIPANTS/MATERIALS SETTING METHOD

We searched the electronic databases of PubMed and EMBASE to identify studies published up to May 2017. We also searched for websites regarding LAC, LARC methods, and UP including, for example, those from the United Nations, the World Health Organization, Pan American Health Organization, the Alan Guttmacher Institute and the United States Agency for International Development. Studies were included if they investigated mainly UP and their consequences as well as the use of LARC methods in the region. During 3 days of meetings, the importance of the studies identified and the appropriateness of inclusion were discussed.

MAIN RESULTS AND THE ROLE OF CHANCE

LAC is not one unit and shows great ethnic diversity as well as economic and cultural differences among the various countries. These differences must be taken into account when developing policies related to disseminating information and combatting misinformation regarding the use of LARC among different audiences, such as adolescents and young women, nulligravidas, indigenous populations and women with disabilities. Furthermore, only some governments have made efforts to increase accessibility to LARC methods, and there is a need to implement training programmes for HCPs, launch education campaigns for the general public, increase access and review the cost-benefit analyses specific to LARC, which have already demonstrated that the upfront cost of LARC is less than the cummulative expense of short-term contraceptives. Recommendations to achieve these goals are presented.

LIMITATIONS REASONS FOR CAUTION

Knowledge and awareness of the contraceptive method itself and of the mix of individual countries in the region is essential to the development of specific strategies and actions, tailored to each particular country situation, aimed at increasing access to modern contraceptive methods, especially LARC.

WIDER IMPLICATIONS OF THE FINDINGS

Healthcare systems in LAC should consider LARC as a primary option for decreasing UP and adolescent pregnancy. Disseminating information, increasing awareness of their efficacy, removing barriers and improving access to LARC methods are the urgent actions recommended for government, academia, professional organizations, insurance companies and policymakers in order to address this major public health problem in LAC.

Pregnancy outcomes associated with extended use of the 52-mg 20 μg/day levonorgestrel-releasing intrauterine system beyond 60 months: A chart review of 776 women in Brazil

OBJECTIVE

To assess the contraceptive performance of the 52-mg 20 μg/day levonorgestrel-releasing intrauterine system (LNG-IUS, Mirena; Bayer Oy, Turku, Finland) among women who maintain the same device without changes after 60 months.

STUDY DESIGN

This is a chart review study in which we assessed the charts of 766 women who continue the same LNG-IUS for contraception beyond 60 months. The women were evaluated at the Family Planning clinic, University of Campinas Medical School, Campinas, SP, Brazil, from November 1990 to March 2011. We obtained sociodemographic data, duration of use, continuation and discontinuation rates and reasons, bleeding pattern at the recorded last visit. The statistical analysis was performed using Kaplan-Meier analysis.

RESULTS

A total of 776 charts were identified of women who used the LNG-IUS beyond 60 months. The mean age (±S.E.M.) at LNG-IUS placement was 32.0±0.2 years (ranged 15 to 44 years; median was 32 years). The distribution of number of pregnancies was 0-1 (45%); 2-4 (54.1%) and≥5 (0.9%). The median length of the LNG-IUS' use was 73 months after placement (ranged 61-184 months). Zero pregnancies were reported and the main reasons for discontinuation were expiration of approved effective lifespan, menopause and planning pregnancy. The cumulative women-years (W-Y) of exposure were 967 and 1403 up to seven and 15 years, respectively. The main bleeding pattern reported by the women was amenorrhea.

CONCLUSIONS

The 52-mg 20 μg/day LNG-IUD (Mirena) showed continue contraceptive efficacy beyond 5 years of use with no pregnancies detected over 967 and 1403 W-Y up to seven and 15 years after placement.

IMPLICATIONS STATEMENT

The 52-mg 20 μg/day LNG-IUD presented a very high contraceptive efficacy beyond the first 5 years of lifetime labeled. Increasing data support that efficacy beyond 5 years of use, and new data suggested efficacy as long as 15 years. Healthcare professionals, policy makers and stakeholders could take advantage of the present information to decide to maintain the same device at least up to seven years. Furthermore, amenorrhea could be a good indicator of contraceptive effect.

Relationship between user satisfaction with the levonorgestrel-releasing intrauterine system and bleeding patterns

AIM

Satisfaction with a contraceptive method constitutes an important factor in its acceptance and long-term use. The objective of this study was to assess the relationship between user satisfaction with the 20-μg/day levonorgestrel-releasing intrauterine system (LNG-IUS) and the bleeding patterns reported at two different time-points during follow-up.

METHODS

A total of 251 LNG-IUS users aged 18-45 years were invited to answer a questionnaire on their return to the clinic for a routine follow-up visit and again 1 year later. Data were collected face-to-face.

RESULTS

Twenty women discontinued prematurely; therefore, the analysis was performed on 231 women. Most users were either highly satisfied (66.6% and 66.2% at the first and second interviews, respectively) or satisfied (26.4% and 26.4% at the first and second interviews, respectively) with the LNG-IUS. Satisfaction was related to amenorrhea (P < 0.001) and duration of use (P < 0.001). Prolonged bleeding and spotting were the main causes of dissatisfaction with the device.

CONCLUSION

Most LNG-IUS users in this sample were satisfied with the device. The only two factors associated with satisfaction were amenorrhea and duration of use, while prolonged bleeding and spotting were the main causes of dissatisfaction. These findings could be useful for health-care professionals and policy-makers when developing information material for women. The study provides insight into the profile of satisfied LNG-IUS users; however, this information is not suitable for counseling women who are considering using an LNG-IUS.

Estimated disability-adjusted life years averted by free-of-charge provision of the levonorgestrel-releasing intrauterine system over a 9-year period in Brazil

BACKGROUND

The objective was to analyse the contribution of the provision at no cost to users of the 20 µg/day levonorgestrel-releasing intrauterine system (LNG-IUS) towards disability-adjusted life years (DALY) averted over a 9-year period.

METHODS

We analysed data from 15 030 new users of the LNG-IUS who had the device inserted at 26 Brazilian teaching hospitals between January 2007 and December 2015. The devices came from the International Contraceptive Access Foundation (ICA), a not-for-profit foundation that donates the devices to developing countries for use by low-income women who desire long-term contraception and who freely choose to use this device. Estimation of the DALY averted included live births averted, maternal morbidity and mortality, child mortality and unsafe abortions averted.

RESULTS

A total of 15 030 women chose the LNG-IUS as a contraceptive method during the study period. Over the 9 years of evaluation, the estimated cumulative contribution of the Brazilian program in terms of DALY averted consisted of 486 live births, 14 cases of combined maternal mortality and morbidity, 143 cases of child mortality and 410 unsafe abortions.

CONCLUSIONS

Provision of the LNG-IUS at no cost to low-income Brazilian women reduced unwanted pregnancies and probably averted maternal mortality and morbidity, child mortality and unsafe abortions. Family planning programs, policymakers and stakeholders based in low-resource settings could take advantage of the information that the provision of this contraceptive at no cost, or at affordable cost to a publicly-insured population, is an effective policy to help promote women's health.

Contraceptive sales in the setting of the Zika virus epidemic

STUDY QUESTION

Has there been any influence of the Zika virus (ZIKV) outbreak on the sales of contraceptive methods in Brazil?

SUMMARY ANSWER

Contraceptive sales in the 24 months of evaluation showed little variation and no significant change has been observed since the ZIKV outbreak.

WHAT IS KNOWN ALREADY

Transmission of ZIKV is primarily by Aedes aegypti mosquitoes; however, sexual transmission has also been described. The association of several birth defects and the ZIKV infection during pregnancy has been established, and it was estimated in Bahia, Brazil that the infection rate could range from 10% to 80%. The World Health Organisation (WHO) declared the cluster of microcephaly cases and other neurological disorders a health emergency on 1 February 2016. The Brazilian government also made recommendations for women who were planning to become pregnant and who reside in ZIKV-affected areas to reconsider or postpone pregnancy.

STUDY DESIGN, SIZE, DURATION

The objective of this study was to assess the sales of contraceptive methods in Brazil, tracking it from before and through the ZIKV outbreak. We obtained information from all pharmaceutical companies based in Brazil and from the manufacturers of long-acting reversible contraceptives (LARCs), including the copper-intrauterine device (IUD), the levonorgestrel-releasing intrauterine system (LNG-IUS) and implants, about contraceptives sales in the public and private sectors between September 2014 and August 2016.

PARTICIPANTS/MATERIALS, SETTING, METHODS

We analyzed the data for: (i) oral contraceptives, i.e. combined oral contraceptives (COC) and progestin-only pills (POP), and vaginal and transdermal contraceptives, (ii) injectable contraceptives, i.e. once-a-month and depot-medroxyprogesterone acetate, (iii) LARCs and (iv) emergency contraceptive (EC) pills.

MAIN RESULTS AND THE ROLE OF CHANCE

Monthly sales of COC, POP, patches and vaginal rings represent the major sales segment of the market, i.e. 12.7-13.8 million cycles/units per month (90%). The second largest group of sales was injectables, representing 0.8-1.5 million ampoules per month (9.5%). Following this, are LARC methods with sales of 37 000-41 000 devices per month (0.5%). It is important to note that although the peak months of sales were different for each group of contraceptives, there were no significant differences overall between the months of observation. The EC pill sales were between 1.0 million and 1.3 million of pills per month.

LIMITATIONS, REASONS FOR CAUTION

Although the use of contraceptive methods was already high and no change was noted, the ZIKV outbreak may have changed the pregnancy intentions of Brazilian women. Consequently, the number of women planning pregnancy may be lower than that recorded. The contraceptive sales figures did not include condoms. Since condoms might not only prevent pregnancies, but also sexual transmission of ZIKV, this lack of information is a limitation.

WIDER IMPLICATIONS OF THE FINDINGS

The results from this assessment showed that the sales of contraceptives presented little variation during the ZIKV outbreak in Brazil. Furthermore, it is possible that access to LARC methods was limited. Although we did not investigate the reason for low LARC uptake, we suspect that it is due to lack of availability of LARC in the public sector, the high cost of the methods and the incomplete insurance coverage on contraception for women. Projections estimate millions of additional cases of ZIKV transmission. Thus, a coordinated response is needed to ensure access to a wide range of contraceptive methods for women during the ZIKV outbreak. In conclusion, this assessment of contraceptive sales in Brazil identifies challenges in contraceptive access, especially for LARC methods, and represents an alternative source of data to help us understand the trends in demand for contraception in ZIKV-affected areas.

Comparison of two cohorts of women who expulsed either a copper-intrauterine device or a levonorgestrel-releasing intrauterine system

AIM

To assess if there is a difference in the characteristics of the women who expelled a copper-intrauterine device (TCu-IUD) or the levonorgestrel-releasing intrauterine system (LNG-IUS) and the frequency of expulsions over different periods of observation.

METHODS

We retrospectively analyzed 19 697 medical charts of women consulting between January 1980 and December 2013 who requested a TCu-IUD or a LNG-IUS.

RESULTS

The medical records of 17 644 Cu-IUD and 2053 LNG-IUS users returning to the clinic for a follow-up visit after insertion of an IUC were reviewed. Of these, 1532 Cu-IUD and 254 LNG-IUS parous users were found to have expelled the IUC for a first time. The mean age at insertion (± standard deviation) was 26.3 ± 6.6 years (range 16-49) for Cu-IUD users and 31.7 ± 7.6 years (range 18-48) for LNG-IUS users (P < 0.001). A total of 263 (13.4%) and 12 (4.3%) of the Cu-IUD and the LNG-IUS users were ≤19 years old, and 49.1% and 54.1% of the expulsions among the Cu-IUD and LNG-IUS users, respectively, were reported in the first six months after placement. A regression model showed that the variables significantly associated with an expulsion of either a Cu-IUD or LNG-IUS were age < 25 years, less than two deliveries and using a Cu-IUD.

CONCLUSION

Our findings showed that the characteristics associated with IUC expulsion were age under 25 years, having had less than two deliveries and being users of Cu-IUD.

Knowledge and attitudes of Latin American obstetricians and gynecologists regarding intrauterine contraceptives

Background

Intrauterine contraceptives (IUCs), including the copper intrauterine device and the levonorgestrel-releasing intrauterine system (LNG-IUS), are among the reversible contraceptive methods with high effectiveness. However, use is low in many settings, including some Latin American countries, mainly due to the influences of myths, fears, and negative attitudes, not only of users and potential users, but also of different cadres of health care professionals. The purpose of this study was to assess the knowledge and attitudes of a group of Latin American obstetricians and gynecologists regarding IUCs.

Methods

A survey was conducted during a scientific meeting organized in Chile in 2014 to present and discuss updated information about contraception. Obstetricians and gynecologists from 12 Latin American countries, who reported that they provide daily contraception services in both the public and private sectors, participated in the meeting. Participants who agreed to take part in the survey responded to a multiple-choice questionnaire on issues regarding knowledge, use, and attitudes about IUCs.

Results

Of the 210 obstetricians and gynecologists participating in the meeting, the respondents to each question varied from 168 (80.0%) to 205 (97.6%). Almost 50% recognized that the failure rate of combined oral contraceptives, patches, and vaginal rings is 8%–10%. Furthermore, 10% of the participants did not recognize the high contraceptive effectiveness of long-acting reversible contraceptive methods. Additionally, almost 80% of the respondents answered that they did not offer IUCs to nulligravidas and almost 10% did not offer IUCs to adolescents, albeit almost 90% of the respondents reported that nulligravidas are candidates for an LNG-IUS.

Conclusion

Some deficiencies and contradictions in terms of knowledge and attitudes were identified from the answers of the Latin American obstetricians and gynecologists who participated in the survey. The knowledge and attitudes of health care professionals about IUCs are important in order to provide adequate counseling and to expand the use of IUCs.

Effect of vaginal administration of misoprostol before intrauterine contraceptive insertion following previous insertion failure: a double blind RCT

STUDY QUESTION

Is pretreatment with misoprostol useful in insertion of intrauterine contraceptives (IUCs) after insertion failure at the first attempt?

SUMMARY ANSWER

Pretreatment with intravaginal administration of 200 mcg of misoprostol after IUC insertion failure 10 and 4 h before the second attempt of IUC placement was significantly better than placebo at facilitating the insertion of an IUC.

WHAT IS KNOWN ALREADY

One of the reasons for low use of IUCs is the concept that insertion is difficult. Misoprostol was used in several randomized clinical trials (RCT) before IUC insertion to facilitate the insertion. In general, the results showed no significant differences when compared with placebo. However, most previous studies have been carried out among unselected women whereas the present study is among women with previous insertion failure.

STUDY DESIGN, SIZE, DURATION

This was a double blind RCT conducted between February 2013 and October 2014. Participants were 104 women who requested an insertion of an IUC and the insertion failed at the first attempt. After insertion failure, the women received a sealed envelope with misoprostol or placebo. The randomization system (1: 1) in one block size was computer-generated.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The study was conducted at a tertiary care centre. The women were instructed to insert vaginally one tablet of misoprostol 200 µg (Prostokos, Hebron, Cariacica, PE, Brazil) or placebo 10 and 4 h before the woman returned to the clinic for a new insertion attempt. The outcomes were successful IUC insertion and the use of a cervical dilator immediately prior to the insertion procedure.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 2639 women requested the insertion of an IUC during the study period. The IUC was inserted at the first attempt in 2535 women (96%) and 104 women in whom we were unable to insert the device were eligible to participate in the RCT. Four women declined and 100 women were randomized (55 for the misoprostol group and 45 for the placebo group). From the 100 participating women, the levonorgestrel-releasing intrauterine system (LNG-IUS) was chosen by 55 and 37 women and the TCu380A intrauterine device (Cu-IUD) was chosen by none and 8 women in the misoprostol and placebo group, respectively. Seven and three women allocated to misoprostol and placebo, respectively, never returned to the clinic after randomization. We placed the IUC in 42 (87.5%) out of the 48 women and in 26 (61.9%) out of the 42 women randomized to misoprostol and placebo, respectively (P = 0.0066). Regarding the Evaluable Population the relative risk (RR) of successful insertions was 1.41 (95% confidence interval (CI) for absolute difference (8.2, 43.0), P = 0.0066); in the Intent-to-Treat Population the RR (95% CI) was 1.32 (0.3, 36.9). Multiple regression analysis showed that the significant variables associated with the insertion failure were the number of Caesarean section ≥1 (P = 0.020) and the use of placebo (P = 0.026). Dilators were used in 21 (43.7%) out of the 48 and 21 (50%) out of the 42 women randomized to misoprostol and placebo, respectively (P = 0.804).

LIMITATIONS, REASONS FOR CAUTION

The limitations were that the majority of the women chose the LNG-IUS, and consequently the data for the Cu-IUD were limited, and there was a small number of nulligravidas.

WIDER IMPLICATIONS OF THE FINDINGS

The results show that IUC insertion difficulties and failures are not common. Pretreatment with intravaginal misoprostol facilitated IUC insertion after failure of insertion at the first attempt, and insertion failure was associated with number of Caesarean sections.

Knowledge and attitudes of Latin American gynecologists regarding unplanned pregnancy and use of combined oral contraceptives

Background

Unintended pregnancy is a public health problem and unmet medical need worldwide. It is estimated that in the year 2012, almost 213 million pregnancies occurred, and the global pregnancy rate decreased only slightly from 2008 to 2012. It was also estimated that 85 million pregnancies (40% of all pregnancies) were unintended and that 38% ended in an unintended birth.

Objectives

To assess knowledge and attitudes of Latin American (LA) obstetricians and gynecologists (OBGYNs) regarding unintended pregnancies and aspects of combined oral contraceptive (COC) use.

Methods

A survey was conducted during a scientific meeting about contraception in 2014, in which OBGYNs from 12 LA countries who provide attention in contraception were invited to respond to a multiple-choice questionnaire to assess their knowledge and attitudes regarding unplanned pregnancy and some aspects regarding COC use.

Results

A total of 210 OBGYNs participated in the study. Their knowledge regarding COC failure was low. The participants reported they believed that their patients habitually forgot to take a pill and that their patients did not know what to do in these situations. They were aware of the benefits of COC use; however, they were less prone to prescribe COCs for the purpose of protecting against ovarian and endometrial cancer, and one-quarter of them had doubts about the association between COC use and cancer risk.

Conclusion

The interviewed LA OBGYNs showed some flaws in terms of knowledge of COC failure rates and the non-contraceptive benefits and risks of COCs. To adequately counsel their patients regarding COC intake, OBGYNs must be updated regarding all aspects of COC use.
