Continuation rates of the subdermal contraceptive Implanon(®) and associated influencing factors

Offering extended use of the contraceptive implant via an implementation science framework: a qualitative study of clinicians' perceived barriers and facilitators

BACKGROUND

The etonogestrel contraceptive implant is currently approved by the United States Food and Drug Administration (FDA) for the prevention of pregnancy up to 3 years. However, studies that suggest efficacy up to 5 years. There is little information on the prevalence of extended use and the factors that influence clinicians in offering extended use. We investigated clinician perspectives on the barriers and facilitators to offering extended use of the contraceptive implant.

METHODS

Using the Consolidated Framework for Implementation Research (CFIR), we conducted semi-structured qualitative interviews. Participants were recruited from a nationwide survey study of reproductive health clinicians on their knowledge and perspective of extended use of the contraceptive implant. To optimize the diversity of perspectives, we purposefully sampled participants from this study. We used content analysis and consensual qualitative research methods to inform our coding and data analysis. Themes arose deductively and inductively.

RESULTS

We interviewed 20 clinicians including advance practice clinicians, family medicine physicians, obstetrician/gynecologist and complex family planning sub-specialists. Themes regarding barriers and facilitators to extended use of the contraceptive implant emerged. Barriers included the FDA approval for 3 years and clinician concern about liability in the context of off-label use of the contraceptive implant. Educational materials and a champion of extended use were facilitators.

CONCLUSIONS

There is opportunity to expand access to extended use of the contraceptive implant by developing educational materials for clinicians and patients, identifying a champion of extended use, and providing information on extended use prior to replacement appointments at 3 years.

Barriers and Facilitators of Extended Use of the Contraceptive Implant: A Cross-Sectional Survey of Clinicians

BACKGROUND

The U.S. Food and Drug Administration (FDA) approved the etonogestrel contraceptive implant for 3 years of use. Evidence suggests that it may be used for up to 5 years for pregnancy prevention, also known as extended use.

METHODS

We conducted a national cross-sectional survey among a group of reproductive health clinicians. We developed an online survey using the Consolidated Framework for Implementation Research (CFIR) and distributed it through e-mail listservs and social media groups from May to June 2021. We analyzed results using multivariable logistical regression.

RESULTS

Among the 300 respondents, 195 (65.0%) reported that they always offer extended use, and 50 (16.7%) reported that they sometimes offer extended use. Fifty-five respondents (18.3%) reported that they never offer extended use. After adjusting for age, gender, and clinical setting, we found that complex family planning sub-specialists (adjusted odds ratio [aOR] = 9.32; 95% confidence interval [CI] [1.81, 48.03]) and family medicine physicians (aOR = 4.37, 95% CI [1.58, 12.10]) were significantly more likely to recommend extended use compared with general obstetrics and gynecology (OBGYN) physicians. Clinicians from private practices or health maintenance organizations were significantly less likely to offer extended use than those from academic centers (aOR = 0.19, 95% CI [0.07, 0.51]; aOR = 0.06, 95% CI [0.01, 0.31]). The most common barriers to offering extended use were concerns about pregnancy risk, bleeding, and lack of FDA approval in the past 3 years. Meanwhile, clinicians identified strong published evidence supporting extended use as a key facilitator for offering it, and they perceived that prior counseling on extended use from a past clinician was a key facilitator for patients to adopt it.

CONCLUSIONS

One-third of clinicians in this study did not consistently offer extended use of the contraceptive implant. An opportunity exists to expand access to extended use by focusing on education interventions for clinicians and seeking FDA approval for 5 years of use.

Early removal of the etonogestrel contraceptive implant in Spanish women: a prospective cohort study

Purpose

To know the discontinuation rate and characterize predictors and reasons of contraceptive implant removal within 12 months of insertion in our community setting.

Methods

This prospective cohort study included women receiving the etonogestrel contraceptive implant at sexual and reproductive health centers between September 2019 and September 2020. The variables collected were implanted insertion timing, reproductive and demographic characteristics, medical conditions, sexual activity and counseling. Our primary outcome was implant discontinuation. Kaplan-Meier survival curves were used to show the cumulative discontinuation rate of implants contraceptive within the first year of insertion. We also identified factors that increased the risk of implant removal using the log-rank test and the Cox regression model. Reasons for discontinuation were documented.

Results

199 women were followed up. Implant discontinuation was documented in 17.1% of implant users prior to 12 months. Factors that increase the risk of implant removal are living with a partner, being aged 25-34 years and not receiving comprehensive and structured counseling from the midwife. The main reason for removal was unsatisfactory bleeding (97.1%), but this was combined with other reasons such as cessation of sexual intercourse (58.8%), worsening mood (58.8%), weight gain (55.9%) or decreased libido (50.0%).

Conclusion

The rate of discontinuous implant uses in the first year is relevant in relation to cost-effectiveness, there is room for improvement that should not be overlooked. Comprehensive and structured midwife-led counseling can reduce early implant abandonment removal. The development in different countries of the role of midwives in the management of contraceptives can contribute to the economic benefit of health services and the satisfaction of women.

Continuation Rates of the Etonogestrel Implant and Factors Associated With Early Discontinuation

BACKGROUND

The etonogestrel implant is generally considered an effective, three-year, long-acting reversible contraceptive device. Previous research, such as the landmark CHOICE study, has reported a one-year continuation rate of 72% to 84%, however, in a real-world setting these rates may be significantly lower.

OBJECTIVE

To study etonogestrel implant continuation rates and factors associated with early discontinuation in a specific clinical setting.

STUDY DESIGN

Single-center, retrospective cohort study of patients who received the etonogestrel implant between January 1, 2015, and December 31, 2017, at several practices at an academic community hospital network. Records were reviewed up to three years after implant insertion to determine continuation rates (one to three years), early discontinuation rates (≤12 months), and reasons for early discontinuation. A sample size calculation was performed to guide a subanalysis of side effects.

RESULTS

A total of 774 patients underwent etonogestrel insertion during the study period. The one-year continuation rate was lower than that of the CHOICE study (62% vs. 83%, P <0.001). A subanalysis (n=216) revealed that a majority (82%, n=177) of patients reported side effects. Side effects were more common in patients with early discontinuation compared with patients who continued use longer than one year (93% vs. 71%, P <0.001). The most common side effect, abnormal uterine bleeding, was not significantly associated with early discontinuation. A significant association (P=0.02) was found between early discontinuation and neurologic/psychiatric complaints.

CONCLUSIONS

The one-year continuation rate of the etonogestrel implant in our population is significantly lower than the value reported by CHOICE. Implant side effects are common and significantly affect rates of discontinuation. Our data suggest there is an opportunity for education and counseling for individuals opting for this method of long-acting contraception.

Satisfaction With the Use of Subdermal Contraceptive Implant in Women Attending the Specialized Polyclinic Primary Health Care Center in Jeddah City: A Cross-Sectional Study

Background Subdermal contraceptive implants are a convenient method of contraception for many women due to the ease of insertion and removal and because they require less follow-up with their health facility. In addition to the contraceptive benefits, women's satisfaction with such devices is essential, as this can affect their quality of life. This study aims to measure women's satisfaction with the subdermal contraceptive implant, Implanon® (Organon & Co., Jersey City, New Jersey, United States), its main side effects, and reasons for removal.  Methods A cross-sectional study was conducted on women between the ages of 19 and 65 years who visited the Family Planning Clinic at the Specialized Polyclinic Primary Health Care Center in Jeddah, Saudi Arabia, between January 2018 and December 2021. An online questionnaire was distributed to the women who had Implanon inserted and 84 responded. Demographic and contraceptive data were collected, including the dates of insertion and removal of Implanon and side effects experienced while on Implanon.  Results Of the 84 women, 65.84% were satisfied with Implanon, while only 19.04% were unsatisfied with the implant. The most common side effect reported was weight gain (54.76%), followed by menstrual Irregularity. (39.29%). The most common reason for removal was the end of the implant's contraceptive duration (42.86%).  Conclusion Most of the women treated at this primary healthcare clinic were satisfied with Implanon. In addition, most of the women removed the implant only due to its reaching the end of its contraceptive duration despite experiencing side effects, and most women said that they would recommend it to their family and friends.

Discontinuation of long acting reversible contraceptive use and its determinants among women in Ethiopia: Systematic review and meta-analysis

Introduction

Contraception discontinuation is a major public health issue that leads to unwanted pregnancies and unsafe abortions. Therefore, this systematic review and meta-analysis aimed to estimate discontinuation of contraceptives and its determinants in Ethiopia.

Methods

PubMed, Google Scholar, Scopus, Science Direct, and Addis Ababa University online library were searched. Data were extracted using Microsoft Excel and analyzed using STATA statistical software (v. 14). Publication bias was checked by forest plot, Begg's rank test, and Egger's regression test. To look for heterogeneity, I² was computed, and an overall estimated analysis was carried out. Subgroup analysis was done by region, study setting, and publication. The pooled odds ratio for associated factors was also computed.

Results

Out of 654 studies assessed, 20 met our criteria and were included in the study. The total number of study participants was 8,780. The pooled prevalence of discontinuation of long acting reversible contraceptive use was 36.94% (95% CI: 28.547-45.326). According to sub-group analysis, Amhara region (45%) and institution-based studies (47.9%) had the highest prevalence. The most common reason for contraceptive discontinuation was negative side effect (42.3%).Women experienced side effects (AOR = 2.833:95% CI:2.005-4.003), didn't receive counseling on side effects (AOR = 2.417; 95% CI: 1.591-3.672), didn't appoint follow up (AOR = 2.820; 95% CI: 2.048-3.881), dissatisfied with the given service (AOR = 5.156; 95% CI: 3.644-7.296), and a desire to be pregnant (AOR = 2.366; 95% CI: 1.760-3.182) were predictors of discontinuation of contraceptives.

Conclusion

In Ethiopia, the pooled prevalence of long acting contraceptive discontinuation was high. Side effects, not being informed about side effects, dissatisfaction with the provided service, no insertion follow-up, and a desire to become pregnant were all associated factors. Healthcare professionals should focus on the client's reproductive goals, proper management of side effects, counseling, and post-insertion visits.

Determinants of early discontinuation of etonogestrel sub-dermal implant among reproductive-age women in Legambo district, Northeast Ethiopia: An unmatched case–control study

Objective:

Etonogestrel sub-dermal implant discontinuation is very common in the study area. But evidence on the determinants was limited. So, this study aimed to identify determinants of early discontinuation of etonogestrel sub-dermal implant among reproductive-age women in Legambo district, Northeast Ethiopia.

Methods:

An institution-based unmatched case–control study was conducted on 252 reproductive-age women (84 cases and 168 controls) from 1 February up to 30 April 2020. Systematic random sampling was used to select women, and the data were collected by face-to-face interview using a structured, pretested, and interviewer-administered questionnaire. The collected data were entered into Epi Data version 3.1 and analyzed by SPSS version 23. A binary logistic regression model was used to identify determinants of early discontinuation of etonogestrel sub-dermal implant. Statistical significance was declared at a p value of less than 0.05, and adjusted odds ratio with a 95% confidence interval was used to identify determinants of early discontinuation of etonogestrel sub-dermal implant in the final model.

Result:

In this study, not receiving pre-insertion counseling (adjusted odds ratio = 3.19, 95% confidence interval: (1.61, 6.30)), having a history of abortion (adjusted odds ratio = 2.89, 95% confidence interval: (1.50, 5.54)), contraceptive side effects (adjusted odds ratio = 2.45, 95% confidence interval: (1.99, 3.91)), and not receiving an appointment for a follow-up visit at the time of insertion (adjusted odds ratio = 3.45, 95% confidence interval: (1.89, 5.99)) were determinants of early discontinuation of etonogestrel sub-dermal implant.

Conclusion:

Not receiving pre-insertion counseling, having a history of abortion, contraceptive side effects, and not receiving an appointment for a follow-up visit at the time of insertion were predictors of early discontinuation of etonogestrel sub-dermal implant. Thus, healthcare professionals should give an appointment for a follow-up visit at the time of insertion and provide detailed counseling for all women, not only for those who had had an abortion and contraceptive side effects.

Vaginal Microbiota and Mucosal Pharmacokinetics of Tenofovir in Healthy Women Using a 90-Day Tenofovir/Levonorgestrel Vaginal Ring

Background

A relationship between the vaginal microbiota and tenofovir (TFV) concentrations and activity after topical administration has been previously reported.

Objective

CONRAD A15-138 was a randomized, placebo-controlled Phase I study aimed at characterizing the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of TFV and levonorgestrel (LNG) administered through a vaginal ring (IVR) for 90 days. Herein, we describe changes from baseline in the vaginal microbiota with IVR use and the impact of the vaginal microbiota on mucosal TFV PK.

Methods

The study screened 68 participants and randomized 47 (37 TFV/LNG, 10 placebo), assessing the vaginal microbiota by sequencing the V3-V4 regions of 16S rRNA genes prior to IVR insertion and monthly for 3 months. Concentrations of TFV in vaginal fluid (VF), and TFV and TFV-diphosphate (TFV-DP) in vaginal tissue, and modeled PD against HIV-1 in vitro were measured before and after treatment.

Results

There were no clinically significant changes in relative abundance of vaginal bacterial phylotypes from pre-insertion baseline at any month among active and placebo IVR users. There were no significant changes in community state type (CST) with IVR use. Participants with diverse, anaerobic CST IVA/B microbiota had higher in vivo release of TFV from the IVR compared to women with Lactobacillus-dominated (LbD) microbiota, who had expected in vivo TFV release rates. Median VF TFV concentrations were significantly higher among women with CST IVA/B microbiota in months 1 (3,135 ng/mg VF) and 2 (3,800 ng/mg). Women with LbD microbiota had significantly higher median VF TFV concentration (1,423 ng/mg) and median TFV (103 ng/mg) and TFV-DP (5,877 fmol/mg) tissue concentrations versus women with CST IVA/B microbiota at month 3. All women demonstrated a significant increase from pre-insertion baseline of in vitro HIV-1 inhibition by VF (p values <0.05). PD differences in tissue according to CST, however, were not statistically significant.

Conclusion

TFV/LNG IVR use did not change the vaginal microbiota nor increase the incidence of CST IVA/B. Vaginal microbiota, and in particular CST IVA/B, possibly through increased vaginal pH, impacted in vivo TFV release and cervicovaginal (CV) PK, but both PK and PD data suggest CV protection against HIV-1.

Level and Timing of Implanon Discontinuation and Associated Factors among Women Who Used Implanon in Andabet District, Public Health Facilities, North-West Ethiopia

Background

Implanon discontinuation is unacceptably high in developing countries, including Ethiopia. Furthermore, there is an observed problem of high unintended pregnancy after method discontinuation that strides to program failure. Therefore, the purpose of this study was to assess the level and determinants of Implanon discontinuation among women who used Implanon in Andabet district, public health facilities, North-West Ethiopia, 2017.

Methods

Facility-based cross-sectional study design was employed among 537 women from Feb. 03 to April 28, 2017. Study participants were selected using a systematic random sampling technique. A face-to-face interview was employed to collect data. Epi-Info version 7 was used for data entry and SPSS version 20 for analysis. Both descriptive and analytical statistical analysis was computed. On multivariable binary logistic regression, a p value of less than 0.05 was used to declare statistical significance.

Results

About 37% of Implanon users have discontinued the method before the intended time. About 86% of them discontinued Implanon before two years of insertion. Women who had no live child (AOR = 2.17, 95% CI: 1.25-3.77), women who did not receive preinsertion counseling (AOR = 1.85, 95% CI: 1.15-2.97), women who developed Implanon-related side effect (AOR = 5.17, 95% CI: 3.18-8.40), and women who did not satisfy by the service provided (AOR = 5.40, 95% CI: 3.04-9.57) had higher odds of Implanon discontinuation. On the other hand, women who received appointment follow-up (AOR = 0.23, 95% CI: 0.13-0.41) had lower odds of Implanon discontinuation.

Conclusions

The level of Implanon discontinuation before its intended time was high in the district. Hence, strengthening preinsertion counseling and appointment follow-up as well as improving the clients' level of service satisfaction could increase Implanon's continuation.

A systematic review on clinical effectiveness, side-effect profile and meta-analysis on continuation rate of etonogestrel contraceptive implant

BACKGROUND

Unintended pregnancies (UIP) have a significant impact on health of women and the health budget of countries. Contraception is an effective way to prevent UIPs. The study objective was to collate evidence on clinical effectiveness of etonogestrel subdermal implant (ESI), continuation rate and side effect profile among eligible women of reproductive age group, as compared to levonorgestrel intrauterine system (LNG-IUS), copper intrauterine device (Cu-IUD) and depot medroxy progesterone acetate injections; other types of contraceptive implants were excluded as comparators.

METHODS

The protocol of the systematic review was registered in Prospero (registration number: CRD42018116580). MEDLINE via PubMed, Cochrane library and web of science were the electronic databases searched. A search strategy was formulated and studies from 1998 to 2019 were included. Clinical trial registries and grey literature search was done. Critical assessment of included studies was done using appropriate tools. A qualitative synthesis of included studies was done and a meta-analysis was conducted in RevMan software for continuation rates of ESI as compared to other long acting reversible contraceptives (LARC) e.g. LNG IUS and Cu-IUD.

RESULTS

The search yielded 23,545 studies. After excluding 467 duplicates, 23,078 titles were screened and 51 studies were included for the review. Eight of the 15 studies reporting clinical effectiveness reported 100% effectiveness and overall pearl index ranged from 0 to 1.4. One-year continuation rates ranged from 57-97%; 44-95% at the end of second year and 25-78% by 3 years of use. Abnormal menstruation was the most commonly reported side effect. There was no significant difference in bone mineral density at 1 year follow-up. The meta-analyses showed that odds ratio (OR) of 1-year continuation rate was 1.55 (1.36, 1.76) for LNG-IUS vs. ESI and 1.34 (1.13, 1.58) for copper-IUD vs. ESI; showing that continuation rates at the end of one-year were higher in LNG-IUS and copper-IUD as compared to ESI.

CONCLUSION

ESI is clinically effective and safe contraceptive method to use, yet 1-year continuation rates are lower as compared to LNG-IUS and copper-IUD, mostly attributed to the disturbances in the menstruation.

Prevalence and factors associated with early discontinuation rate of Implanon utilization among women who ever used Implanon in Kucha District Gamo Gofa Zone, Southern Ethiopia

Background

The promotion of contraception in countries with high birth rates has the potential to reduce poverty, hunger, maternal, and childhood deaths. Every year in sub-Saharan Africa approximately 14 million unintended pregnancies occurred and a sizeable proportion was due to poor use of short-term hormonal methods. Contraceptive hormonal implants are highly effective and suitable for almost all women at any stage of their reproductive lives. On the other hand, early discontinuation of the Implanon contraceptive method utilization is one of the foremost problems amid the family planning program. Early discontinuation of the Implanon contraceptive method and reasons for such discontinuation lingers the most significant anxiety for family planning programs. In unindustrialized countries, contraceptive discontinuation due to health concerns is generally higher; these complaints are often related to service quality. Hence, this study aimed to assess the prevalence and factors associated with early discontinuation of Implanon among women who ever used Implanon in Kucha district, Gamo Gofa Zone, Southern Ethiopia.

Methods

Implanon contraceptive device users were selected from the Kucha district using a cross-sectional community-based survey from January to March 2018. A total of 430 women were selected and data were collected through face-to-face interviews by using a pre-tested structured questionnaire. Data were cleaned, coded, and entered into Epi-Info version 7statistical software. Factors that showed association in a bivariate analysis that has a p value of less than 0.25 were entered into multiple logistic regression models for controlling confounding factors. The strength of statistical association was measured by adjusted odds ratio, at 95% confidence intervals, and p value < 0.05 were considered as statistically significant variables.

Result

The result of this study revealed that the overall discontinuation rate of Implanon in the study was 34%. Variables having statistically significant association with Implanon discontinuation were women who never use a contraceptive method other than Implanon (AOR = 2.96, 95% CI 1.53–5.74), women who didn’t make discussion with a partner (AOR = 3.32, 95% CI 1.57–7.04), poor counseling and follow up (AOR = 9.23, 95% CI 4.7–18.13), fear of side effects (AOR = 0.12, 95% CI 0.058- 0.24) and poor satisfaction of service (AOR = 5.2, 95% CI 2.77- 9.76)

Conclusion

The overall early discontinuation rate of Implanon in the study area was high. The main factors associated with early discontinuation of Implanon were contraceptive ever use, discussion with partner, poor follow-up of counseling, fear of side effects, and un-satisfaction by the services given during the insertion rate of Implanon.

Discontinuation of implants use and associated factors among women attending health facility clinics in Hawassa City, Southern Ethiopia, 2019; cross sectional study

Background

Despite improving the availability and use of Implants, discontinuation is becoming a public health concern. A significant proportion of women discontinuing the service before its due date, which is of concern in the health system and its consequence may lead to a program failure. This might have also social and economic consequences for users. Only 8% of married women in Ethiopia use implants. Apart from its low utilization, premature removal is common for unknown reasons. However, there is paucity of information on discontinuation of implants use and associated factors in the study area.

Objective

The study was aimed to assess discontinuation of implants use and associated factors among women attending health facility clinics in Hawassa city, southern Ethiopia, from March, 01-April, 01/2019.

Methods

Facility based cross sectional study design was used. Out of 16 health facilities, 9 of them were selected for this study using simple random sampling. Total sample size of this study was determined to be 351. Data were collected from study subjects using pretested, structured questionnaire through a face-to-face interview. Data was analyzed using descriptive statistics and logistic regression. The result is presented using the Crude Odds ratio as well as Adjusted Odds Ratio with the corresponding 95% confidence level.

Result

Out of 351 study participants, the overall proportion of implants discontinuation was 49.3%(95% CI: 44.2–55.0). Lack of counseling about side effects (AOR = 2.394; 95% CI: 1.422–4.030), developing side effects (AOR = 6.325; 95% CI: 3.719–10.757) and lack of post insertion follow-up (AOR = 2.241; 95% CI: 1.186–4.234) the major factors associated with discontinuation of Implants.

Conclusion and recommendation

In this study, the overall proportion of discontinuation of Implants among women who were using Implants was high. Health professionals could give pre-insertion counseling about side effects and post insertion dates for follow-up to improve of utilization of implants.

Discontinuation of Reversible Long-Acting Contraceptive and Associated Factors among Female Users in Health Facilities of Hawassa City, Southern Ethiopia: Cross-Sectional Study

Background

Despite improvement in the availability and use of reversible long-acting contraception, discontinuation is becoming a public health concern. A significant proportion of women discontinuing the service before its due date, which is of concern in the health system with regard to its consequences, may lead to a program failure. In addition, there is a paucity of information on discontinuation of reversible long-acting contraceptives and associated factors in the study area. Therefore, this study aimed to assess discontinuation of reversible long-acting contraceptives and associated factors among female users in health facilities of Hawassa city, southern Ethiopia, 2019.

Methods

Institution-based cross-sectional design was used. Systematic sampling was used to select study participants. Women who were users of long-acting contraceptives and had come to selected health facilities for method-related reasons were included in the study. Data collectors approached and recruited participants before they contacted their care providers. Data were collected from study subjects using a pretested, structured questionnaire through face-to-face interviews after participants had contacted care providers. Results are presented using the crude and adjusted ORs with corresponding 95% CIs.

Results

The overall proportion of reversible long-acting contraceptive discontinuation was 56.6% (95% CI 52.30%, 61.10%). Maternal education at primary level (AOR 2.33, 95% CI 1.15–4.74), lack of counseling (AOR 2.50, 95% CI 1.01–6.18), side effects (AOR 2.10, 95% CI 1.31–3.34), and desire to be pregnant (AOR 2.22; 95CI 1.50–3.30) were the major factors in discontinuation.

Conclusion

In this study, the overall proportion of discontinuation of reversible long-acting contraceptives was high. Maternal education at primary level, lack of counseling, side effects, and desire to be pregnant were the key factors associated with discontinuation of the contraceptives. Health professionals should provide counseling on the side effects before insertion.

Prevalence of early discontinuation and associated factors among a retrospective cohort of etonogestrel contraceptive implant users

Purpose: To characterise the frequency of and predictors of contraceptive implant discontinuation within 12 months of insertion in our clinical setting.Materials and methods: This retrospective cohort study included women receiving the etonogestrel contraceptive implant at our hospital between May 2007 and May 2012. We abstracted data from charts including implant removal date, bleeding complaints, reproductive and demographic characteristics, prior contraceptive use, tobacco use and implant insertion timing. Our primary outcome was implant discontinuation within 12 months following insertion. SAS 9.4 (SAS Institute Inc., Cary, NC, USA) was used to generate frequencies, bivariate analyses and multivariate logistic regression models.Results: Implant discontinuation was documented in 16% of implant users prior to 12 months (89/544). Women with documented bleeding complaints in the medical record were more likely to discontinue within 12 months (OR: 4.36, CI: 2.71, 7.00). No other demographic or clinical characteristics were associated with premature discontinuation. Having less than two prior pregnancies and tobacco use were associated with documented bleeding complaints.Conclusions: Discontinuation of the implant is associated with bleeding complaints. Women with lower parity and tobacco users may be more likely to experience bleeding or to find it intolerable.

Effect of cost on early removal of contraceptive implants: a prospective cohort study

OBJECTIVES

To evaluate the effect of the cost of subdermal etonogestrel implant (SEI) on the continuation rate one year after insertion, and to assess the reasons given by users to remove the implant before the expiration date.

METHODS

Prospective cohort study conducted among 265 women who chose the SEI as a contraceptive method in a sexual and reproductive health center in the eastern region of Spain, between October/2012 and October/2017. The sample was divided into two cohorts depending on the cost of the implant for the user (free-of-charge or requiring partial payment). Kaplan-Meier survival curves were used to compare the cumulative removal rates of free implants with partially paid implants within the first year of insertion. Cox proportional hazards models were used to control for confounders.

RESULTS

After adjusting for confounders, no significant associations were found between the cost of the implant and its removal within a year of insertion. No significant associations were found in the reasons given for implant removal and for the duration of implant use.

CONCLUSIONS

Cost was not associated with SEI continuation rates within the first year of use. No other significant variables were found to explain implant removal within one year of use.

There might be blood: a scoping review on women's responses to contraceptive-induced menstrual bleeding changes

INTRODUCTION

Concern about side effects and health issues are common reasons for contraceptive non-use or discontinuation. Contraceptive-induced menstrual bleeding changes (CIMBCs) are linked to these concerns. Research on women's responses to CIMBCs has not been mapped or summarized in a systematic scoping review.

METHODS

We conducted a systematic scoping review of data on women's responses to CIMBCs in peer-reviewed, English-language publications in the last 15 years. Investigator dyads abstracted information from relevant studies on pre-specified and emergent themes using a standardized form. We held an expert consultation to obtain critical input. We provide recommendations for researchers, contraceptive counselors, and product developers.

RESULTS

We identified 100 relevant studies. All world regions were represented (except Antarctica), including Africa (11%), the Americas (32%), Asia (7%), Europe (20%), and Oceania (6%). We summarize findings pertinent to five thematic areas: women's responses to contraceptive-induced non-standard bleeding patterns; CIMBCs influence on non-use, dissatisfaction or discontinuation; conceptual linkages between CIMBCs and health; women's responses to menstrual suppression; and other emergent themes. Women's preferences for non-monthly bleeding patterns ranged widely, though amenorrhea appears most acceptable in the Americas and Europe. Multiple studies reported CIMBCs as top reasons for contraceptive dissatisfaction and discontinuation; others suggested disruption of regular bleeding patterns was associated with non-use. CIMBCs in some contexts were perceived as linked with a wide range of health concerns; e.g., some women perceived amenorrhea to cause a buildup of "dirty" or "blocked" blood, in turn perceived as causing blood clots, fibroids, emotional disturbances, weight gain, infertility, or death. Multiple studies addressed how CIMBCs (or menstruation) impacted daily activities, including participation in domestic, work, school, sports, or religious life; sexual or emotional relationships; and other domains.

CONCLUSIONS

Substantial variability exists around how women respond to CIMBCs; these responses are shaped by individual and social influences. Despite variation in responses across contexts and sub-populations, CIMBCs can impact multiple aspects of women's lives. Women's responses to CIMBCs should be recognized as a key issue in contraceptive research, counseling, and product development, but may be underappreciated, despite likely - and potentially substantial - impacts on contraceptive discontinuation and unmet need for modern contraception.

Early Implanon Discontinuation and Associated Factors among Implanon User Women in Debre Tabor Town, Public Health Facilities, Northwest Ethiopia, 2016

Background

Implanon discontinuation closely related to higher rates of overall fertility rate, unwanted pregnancies, and induced abortion. This might have social and economic consequences. In Ethiopia the magnitude of early Implanon discontinuation and contributing factors is not well studied.

Objective

To assess early Implanon discontinuation and associated factors among Implanon user women in Debre Tabor town, 2016.

Methods

A facility based cross-sectional study was conducted from May 1 to August 2016 through face-to-face interview. A total of 449 Implanon user women were selected by systematic random sampling technique. Epi Info version 7 and SPSS version 20 were used for data entry and analysis, respectively. Factors associated with early Implanon discontinuation were analyzed using binary and multivariable logistic regression model. Variables with p value of <0.05 and 95% confidence interval were considered as statistically significant.

Results

The overall proportion of early Implanon discontinuation among mothers was 65 % (95%, CI: 60.4%–69.5%). Having no children (AOR = 2.0, 95% CI = [1.3–4.5]), being not counseled for possible side effects (AOR = 1.50, 95% CI = [1.1–3.4]), having no appointment for follow-up (AOR = 2.6, 95% CI = [1.2–4.3]), and having developing side effects (AOR = 1.7, 95% CI = [1.5–4.4]) were found to be statistically significant factors associated with early Implanon discontinuation.

Conclusion and Recommendation

Early Implanon discontinuation among mothers was found to be high. Hence, counseling about Implanon side effects and appointment for follow-up of Implanon users should be made to increase Implanon retention.

Uptake of long-acting, reversible contraception in three remote Aboriginal communities: a population-based study

OBJECTIVE

To assess the use, effectiveness and acceptance of prescribed contraception in three remote Western Australian Aboriginal communities.

PARTICIPANTS AND DESIGN

Mixed method study, including retrospective file review of contraception methods for 566 regular female Aboriginal patients, 1 November 2010 - 1 September 2014, and semi-structured interviews with 20 Aboriginal women.

SETTING

Primary care clinics in three remote Aboriginal communities.

MAIN OUTCOME MEASURES

Number of episodes of contraceptive use, effectiveness and continuation rates of prescribed contraceptive use; personal experiences, attitudes towards and beliefs about contraception options.

RESULTS

34% of women had used contraception, ranging from 15% of women aged younger than 15 years to 55% of women aged 15-19 years. The most common forms of contraception at the census date were long-acting reversible contraceptives (LARCs): 77% of women using contraception had an etonogestrel implant and 7% had depot medroxyprogesterone. Etonogestrel continuation rates at 1, 2 and 3 years were 87% (95% CI, 81-92%), 72% (95% CI, 64-78%) and 51% (95% CI, 41-60%) respectively. Medroxyprogesterone depot continuation at one year was only 14% (95% CI, 8-22%). Social acceptance of the etonogestrel implant was high; no concerns were raised about stigma or unwanted attention related to implant use.

CONCLUSION

The high uptake of LARCs in these communities is consistent with international recommendations about contraception use. High acceptability was reflected in excellent continuation rates. Service delivery models that use community engagement and capacity building are recommended for broadening the focus of sexual health beyond sexually transmitted disease detection and management, giving priority to the reproductive rights and unmet needs of Aboriginal women.

Twelve-month discontinuation of etonogestrel implant in an outpatient pediatric setting

OBJECTIVE

The etonogestrel (ENG) contraceptive implant is the most effective reversible contraceptive method. Uptake remains limited in adolescents, a population at high risk for unintended pregnancy. The objectives of this study were to determine the 12-month discontinuation rate of the ENG implant among adolescents in an outpatient setting and to characterize risk factors for discontinuation.

STUDY DESIGN

A retrospective chart review identified adolescent females aged 12 to 22years who received the ENG implant in one pediatric institution between January 1, 2011, and April 15, 2014. Patients were categorized into ENG discontinuers (removed prior to 12months) and ENG continuers (continued for ≥12months). Associations between demographic, clinical and postplacement characteristics with ENG discontinuation category were assessed with t tests, χ(2)/Fisher's Exact Tests and backwards stepwise logistic regression.

RESULTS

Of the 750 patients who had an ENG implant inserted, 77 (10.3%) had the device removed prior to 12months of use. The mean length of implant use for those who discontinued was 7.5months. Problematic bleeding was the most commonly cited reason for discontinuation. Older age at time of insertion, history of pregnancy and ≥1 medical visit for implant concerns (not including removal) were independently predictive (p<.01) of method discontinuation.

CONCLUSION

The vast majority of adolescents continued the ENG implant at 12months, making it an excellent contraceptive choice for adolescents within the outpatient pediatric setting. Greater efforts should be made to increase its use by pediatric providers.

IMPLICATIONS

The ENG implant is an excellent contraceptive option for adolescents in the outpatient pediatric setting.

Innate Immunity and Biomaterials at the Nexus: Friends or Foes

Biomaterial implants are an established part of medical practice, encompassing a broad range of devices that widely differ in function and structural composition. However, one common property amongst biomaterials is the induction of the foreign body response: an acute sterile inflammatory reaction which overlaps with tissue vascularisation and remodelling and ultimately fibrotic encapsulation of the biomaterial to prevent further interaction with host tissue. Severity and clinical manifestation of the biomaterial-induced foreign body response are different for each biomaterial, with cases of incompatibility often associated with loss of function. However, unravelling the mechanisms that progress to the formation of the fibrotic capsule highlights the tightly intertwined nature of immunological responses to a seemingly noncanonical “antigen.” In this review, we detail the pathways associated with the foreign body response and describe possible mechanisms of immune involvement that can be targeted. We also discuss methods of modulating the immune response by altering the physiochemical surface properties of the biomaterial prior to implantation. Developments in these areas are reliant on reproducible and effective animal models and may allow a “combined” immunomodulatory approach of adapting surface properties of biomaterials, as well as treating key immune pathways to ultimately reduce the negative consequences of biomaterial implantation.
