Lactogenesis after early postpartum use of the contraceptive implant: a randomized controlled trial. Obstet Gynecol. 2011;117:1114-1121. [PMID: 21508750 DOI: 10.1097/aog.0b013e3182165ee8]

Immediate postpartum contraceptive implant placement and breastfeeding success in postpartum people at risk for low milk supply: A randomized non-inferiority trial

OBJECTIVES

Our goal was to measure the impact of postpartum contraceptive implant insertion timing on breastfeeding success and duration in a population at high-risk for low milk supply.

STUDY DESIGN

We conducted a three-armed randomized non-inferiority study of postpartum people who plan to breastfeed and have known risk factors for low milk supply. Participants were randomized to one of three groups for the timing of implant placement: within 30 minutes of placental delivery, 24-72 hours postpartum, or 6+ weeks postpartum. The primary outcome was time to lactogenesis II (LII). Secondary outcomes included duration and exclusivity of breastfeeding and implant satisfaction through 6 months postpartum.

RESULTS

We enrolled 155 participants. Compared to those who received implants 6+ weeks postpartum, those who received it ≤30 minutes postpartum (mean difference: 2.92 hours, 95% CI: -9.26, 15.1, p = 0.64) or 1-3 days postpartum (mean difference: -0.75 hours, 95% CI: -13.02, 11.51, p = 0.90) had similar time to LII. Similar results were observed for intention to treat analysis. Duration and exclusivity of breastfeeding and implant satisfaction were similar among all groups.

CONCLUSIONS

Unfortunately, our results did not meet the threshold of non-inferiority because the confidence intervals included the 8 hours non-inferiority margin defined a priori. However, our results indicate similar time to LII between groups. Ultimately, our study suggests that early etonogestrel implant insertion does not affect breastfeeding success among postpartum people at risk for low milk supply.

IMPLICATIONS

Etonogestrel implant insertion can be offered anytime postpartum to meet the needs of postpartum people.

Breastfeeding after immediate vs delayed postpartum contraceptive implant placement: a noninferiority randomized controlled trial

BACKGROUND

Breastfeeding and access to contraception are important to patient and public health. The etonogestrel contraceptive implant is a popular and highly effective long-acting progestin contraceptive with few medical contraindications. Despite theoretical concern about early exogenous progestin exposure inhibiting lactogenesis, previous studies showed reassuring lactogenesis and long-term breastfeeding with immediate placement. However, no studies compare placement within 24 hours postpartum to delayed placement at a postpartum visit.

OBJECTIVE

We studied the association between etonogestrel contraceptive implant placement within 24 hours vs at least 2 weeks postpartum and breastfeeding continuation at 8 weeks postpartum.

STUDY DESIGN

We conducted a noninferiority randomized controlled trial of postpartum participants who planned to breastfeed and use the etonogestrel implant at 2 university hospitals in the Mountain West. Participants were at least 13 years old, fluent in English or Spanish, had term deliveries, and lacked contraindications to implant use. They were randomized 1:1 to implant placement within 24 hours or at least 2 weeks postpartum. We collected baseline participant characteristics from chart review and questionnaires. Participants reported breastfeeding status and implant use via electronic questionnaires at 2, 4, 8, 12, and 24 weeks postpartum. The study was powered to assess a 15% noninferiority margin between groups of the primary outcome, any breastfeeding at 8 weeks in the per protocol population.

RESULTS

We enrolled 150 participants (n=78 immediate, n=72 delayed). After removing participants who declined implant placement, withdrew, or were ineligible (n=8) or lacked primary outcome data (n=16), the modified intention-to-treat analysis included 126 participants (n=69 immediate, n=57 delayed). The per protocol analysis included 115 participants (n=62 immediate, n=53 delayed) after excluding additional participants who received the implant outside of the placement timing windows (n=11). Participants were similar in age, race, and ethnicity, as well as previous breastfeeding experience, delivery mode, and epidural use; the delayed group reported prior implant use less frequently (29% vs 43%). In the per protocol analysis, 77.4% (48/62) of participants in the immediate group and 81.1% (43/53) in the delayed group reported any breastfeeding at 8 weeks; the lower limit of the one-sided 95% confidence interval around this -3.7% difference was -16%, exceeding our predefined noninferiority margin. The difference between groups in the modified intention-to-treat group was smaller (-0.6%) and within the noninferiority margin (-12.8% lower limit of the 1-sided 95% confidence interval): 78.3% (54/69) immediate and 78.9% (45/57) delayed. Implant continuation at 24 weeks trended toward favoring immediate placement (96%, 52/54) compared to in those assigned to delayed placement, (85%, 39/46, P=.08). Exclusive or any breastfeeding and implant continuation through 24 weeks were similar between groups.

CONCLUSION

The results demonstrated no clinically important differences in breastfeeding and implant continuation outcomes though our primary outcome exceeded our predefined noninferiority margin. These reassuring data add to the evidence base for supporting etonogestrel implant initiation for breastfeeding people whenever they desire it postpartum.

Immediate vs delayed postpartum insertion of long-acting reversible contraception methods: meta-analysis of randomized controlled trials

OBJECTIVE

We aimed to conduct a meta-analysis of randomized trials comparing the immediate vs delayed provision of long-acting reversible contraceptives in postpartum subjects, focusing on short-interval pregnancies, utilization rates, and adverse events.

DATA SOURCES

Cochrane Central, Embase, PubMed, and ClinicalTrials.gov were systematically searched from inception up to December 19, 2023, without filters or language limitation.

STUDY ELIGIBILITY CRITERIA

We selected randomized controlled trials assessing the immediate insertion of long-acting reversible contraceptives in women during postpartum period in comparison with the delayed provision.

STUDY APPRAISAL AND SYNTHESIS METHODS

We calculated relative risks with 95% confidence intervals to analyze the primary outcome of utilization rates and secondary endpoints, including initiation rates, pregnancy, any breastfeeding, exclusive breastfeeding, and serious adverse events. A random-effects model was employed in the R software. Moreover, we assessed the risk of bias of selected randomized controlled trials using version 2 of the Cochrane Risk of Bias Assessment Tool.

RESULTS

We included 24 randomized trials comprising 2507 participants, of whom 1293 (51.6%) were randomized to the immediate insertion. Postpartum women in the immediate group had lower risk of pregnancy (relative risk 0.16; 95% confidence interval 0.04-0.71; P=.02) compared with delayed group, and higher rates of long-acting reversible contraceptives at 6 months of follow-up (relative risk 1.23; 95% confidence interval 1.09-1.37; P<.01).

CONCLUSION

Inserting long-acting reversible contraceptives before hospital discharge was associated with a reduction in the risk of pregnancy, and increased rates of its utilization at 6 months of follow-up. This intervention may be an effective contraception strategy for postpartum women.

The association of insertion methods on immediate postpartum intrauterine device expulsion rates: A retrospective cohort study

OBJECTIVE

To evaluate the method of immediate postpartum IUD (ppIUD) insertion (manual versus ring forceps) and expulsion rate within 6-week postpartum.

STUDY DESIGN

We performed a retrospective cohort study of patients who had a singleton vaginal delivery and an immediate ppIUD inserted at Rush University from January 2014 to September 2023. The primary outcome was rate of expulsion within 6-week postpartum. We compared the rate of expulsion by method of insertion, either using a manual technique versus using ring forceps. We performed univariable analysis for the association between baseline maternal characteristics and the primary outcome and we performed multivariable logistic regression to determine the independent association of the method of insertion and the primary outcome.

RESULTS

Two hundred nineteen patients met eligibility with 117 immediate ppIUDs inserted manually and 102 inserted with ring forceps. Baseline maternal demographics were similar across study groups. After adjusting for factors selected a priori (estimated blood loss, body mass index, gestational age at delivery, nulliparity, type of IUD), use of ring forceps was more likely to result in expulsion compared to manual insertion (30.4% vs 16.2% respectively; adjusted OR 2.49, 95% confidence interval 1.28-4.90).

CONCLUSION

In this retrospective analysis, insertion of immediate ppIUD with ring forceps was independently associated with an increased rate of expulsion within 6 weeks postpartum when compared to manual insertion.

IMPLICATIONS

In this setting, ring forceps was associated with high rates of immediate postpartum IUD expulsion compared to manual technique. Studies disagree, suggesting need for additional work.

Postpartum contraception: A matter of guidelines

The postpartum period is the perfect time to access family planning services. WHO guidelines contraindicate combined hormonal contraceptives postpartum in breastfeeding patients between 6 weeks and 6 months after delivery (Medical Eligibility Criteria category 3). On the contrary, the Faculty of Sexual and Reproductive Healthcare and the Centers for Disease Control and Prevention guidelines do not contraindicate their use in women who breastfeed from 6 weeks to 6 months postpartum. New combined hormonal contraceptives with natural estrogens have never been studied in this setting. Guidelines agree on the prescription of the progestin-only pill postpartum in non-breastfeeding women (category 1). Differences are found in women who breastfeed. In non-breastfeeding women, an implant is considered safe (category 1) by all guidelines, without any distinction in time. Regarding postpartum breastfeeding women, the guidelines for implants give quite different indications but are still permissive. Intrauterine devices are viable options for postpartum contraception but guidelines give different indications about the timing of insertion. Postplacental intrauterine device placement can reduce the subsequent unintended pregnancy rate, particularly in settings at greatest risk of not having recommended postpartum controls. However, it has yet to be understood whether this approach can really have an advantage in high-income countries. Postpartum contraception is not a 'matter of guidelines': it is the best customization for each woman, as early as possible but at the ideal timing.

Breastfeeding and Hormonal Contraception: A Scoping Review of Clinical Guidelines, Professional Association Recommendations, and the Literature

Background: Postpartum contraceptive use can help prevent short-interval pregnancies, which have been associated with adverse neonatal and maternal health outcomes. Many contraceptive methods are safe for postpartum use, but patients and providers may be confused as to what impact hormonal contraception has on lactation. We performed a scoping review of the most recent U.S.-based guidelines regarding hormonal contraception on lactation to provide synthesis and recommendations to aid providers in counseling their patients. Methods: We conducted a scoping review by identifying the most recent clinical recommendations and guidelines from the Centers for Disease Control and Prevention (CDC) and three maternal and child health professional associations (American College of Obstetricians and Gynecologists [ACOG], Society for Maternal-Fetal Medicine [SMFM], and Academy of Breastfeeding Medicine [ABM]). We also reviewed the citations in these guidelines used in their development. We then conducted an updated literature review to capture studies published since the most recent systematic reviews were conducted. Results: We reviewed 1 clinical guideline from the CDC and 2 systematic reviews cited in its references, 6 professional association recommendations, and 28 publications identified through the updated literature review. Progestin-only contraceptive methods continue to demonstrate safety in breastfeeding patients, while low-quality evidence supports concerns of decreased milk supply with combined hormonal contraception. Discussion: Organizations should consider updating counseling recommendations regarding progestin-only contraceptives and lactation. Further research is needed to examine new contraceptive methods as well as the effect of hormonal contraception on lactation in the setting of preterm birth.

One-year follow-up of immediate postpartum contraceptive implant insertion in adolescents

PURPOSE

Our study aimed to evaluate the acceptability, adverse effects and continuation rates among adolescents who accepted the etonogestrel (ENG) subdermal implant and compared to adolescents who chose other methods during the immediate postpartum period before hospital discharge, with one year follow-up up.

MATERIALS AND METHODS

We conducted a cohort non-randomised study at the Women's Hospital, University of Campinas. All women up to 19 years of age, who gave birth at the hospital between July 2019 and April 2020, were invited to participate and were offered the ENG-implant or the routine contraceptive methods. They were followed for one year postpartum.

RESULTS

We included 100 teenagers and 72 accepted the ENG-implant. Students are more likely to accept the ENG-implant than non-students (PR: 1.25 [95%CI 0.99-1.59]). Up to one year of follow-up, survival analysis showed that the time of adherence to the method was longer for the ENG-implant users (p = 0.0049). More than 90% of the adolescents were satisfied with the implant; however, five requested early removal due to menstrual irregularity and local discomfort.

CONCLUSION

Provision ENG-implant for adolescents in the immediate postpartum demonstrated high acceptance and ensured effective contraception. After one year, most of them were satisfied, with a high continuation rate and without unplanned pregnancies.

The safety and efficacy of immediate post placental IUD insertion versus the post puerperal IUD insertion in women undergoing cesarean delivery.. [DOI: 10.21203/rs.3.rs-2412988/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Objective asses the safety and efficacy of immediate IUD insertion following delivery of the placenta in women undergoing cesarean delivery. Study: Randomized clinical trial that included 66 women, were divided equally in two arms, where each arm included 33 patients. The first group had IUD inserted 10 min after delivery of the placenta (post placental group) and the second group had their IUD inserted at 6weeks following delivery (interval group). Results The complication rate related to post placental IUD insertion was comparable to that of interval insertion. The expulsion and displacement rates were the same in both post placental and interval groups at 6 weeks and 3 months follow up. Conclusion Post placental IUD insertion is a safe and attractive option for postpartum contraception that should be offered to all women undergoing elective cesarean section after proper counseling.

A cross-sectional study of factors associated with immediate postpartum uptake of contraceptive implants in Papua New Guinea

OBJECTIVES

In 2016 the Port Moresby General Hospital in Papua New Guinea introduced a midwife led postpartum contraception service to educate patients and provide contraceptive implants. This study examines the factors that were associated with immediate postpartum uptake of the implants.

STUDY DESIGN

We conducted a cross-sectional study of patients on the hospital postnatal ward who gave birth between March 2017 and January 2018. Patients aged 16-45 who had a vaginal birth with a singleton, live baby not requiring admission to the special care nursery were eligible for inclusion and invited to complete a survey prior to discharge.

RESULTS

Of 2082 patients approached, all consented to participate in the survey. Of those completing the survey, 531 (25.5%) chose to have the contraceptive implant provided immediately postpartum. Excluding patients who chose tubal ligation (n = 330), in multivariable analysis, higher odds of implant uptake was associated with no prior contraception use compared to prior use (aOR 1.38; 95% CI 1.07 -1.77), unplanned pregnancy compared to planned (aOR 1.37, 95% CI 1.07-1.79), and having received antenatal education about the implant compared to no information (AOR 1.65, 95% CI 1.23-2.10).

CONCLUSIONS

Antenatal education about the contraceptive implant impacted on likelihood of immediate postpartum method uptake. Patients who had no prior use of contraception and those with unplanned pregnancies were also more likely to request the implants, suggesting that the midwife-led postpartum service is successfully reaching patients with a previous unmet need for contraception.

IMPLICATIONS

This study demonstrates successful delivery of a postpartum implant program in a setting where community access to contraception is limited. Antenatal information and education can support implant uptake and that the program provides the opportunity for birth spacing and limiting in patients with a previous unmet need.

Lactogenesis and breastfeeding after immediate vs delayed birth-hospitalization insertion of etonogestrel contraceptive implant: a noninferiority trial

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.

Placement of long-acting reversible contraception for minors who are mothers should not require parental consent

Decreasing unintended teenage pregnancy, especially repeat teenage pregnancy, is an important public health goal. Unfortunately, legal barriers in the USA impede this goal as all minors are unable to consent for birth control in 24 states, and only 10 of those states allow consent after the minor has given birth according to state statutory law. Placement of long-acting reversible contraception (LARC) is one of the most effective methods of preventing rapid repeat pregnancies. However, restrictions are placed on adolescents who may not have the option of parental consent if the parents are unwilling, or not present, to give consent. A predicament arises when healthcare professionals are willing to place the contraceptive for the patient, but cannot due to the restrictions and guidelines outlined by each state. Even though these adolescents are legally viewed as minors, adolescent mothers should be able to consent to the placement of LARC. Notably, adolescents have the legal ability to give consent for the healthcare of their child starting in the prenatal period. I argue that this ability should be extended to include adolescent consent for their own healthcare. Additionally, the procedure to place LARC is relatively low risk and highly effective, which is an opportune situation to allow minors to consent. Allowing adolescents to consent to LARC after delivery is a simple and effective way to decrease rapid repeat pregnancy rates in the USA.

Immediate versus delayed postpartum insertion of contraceptive implant and IUD for contraception

BACKGROUND

Long-acting reversible contraception (LARC), including intrauterine devices (IUDs) and contraceptive implants, are highly effective, reversible methods of contraception. Providing LARC methods during the postpartum period is important to support contraceptive choice, and to prevent unintended pregnancy and short interpregnancy intervals. Delaying offering contraception to postpartum people until the first comprehensive postpartum visit, traditionally at around six weeks postpartum, may put some postpartum people at risk of unintended pregnancy, either due to loss to follow-up or because of initiation of sexual intercourse prior to receiving contraception. Therefore, immediate provision of highly effective contraception, prior to discharge from hospital, has the potential to improve contraceptive use and prevent unintended pregnancies and short interpregnancy intervals.

OBJECTIVES

To compare the initiation rate, utilization rates (at six months and 12 months after delivery), effectiveness, and adverse effects of immediate versus delayed postpartum insertion of implants and IUDs for contraception.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and POPLINE for eligible studies up to December 2020. We examined review articles and contacted investigators. We checked registers of ongoing clinical trials, citation lists of included studies, key textbooks, grey literature, and previous systematic reviews for potentially relevant studies.

SELECTION CRITERIA

We sought randomized controlled trials (RCTs) that compared immediate postpartum versus delayed insertion of contraceptive implant and IUDs for contraception.

DATA COLLECTION AND ANALYSIS

Two review authors (JS, SK) independently screened titles and abstracts of the search results, and assessed the full-text articles of potentially relevant studies for inclusion. They extracted data from the included studies, assessed risk of bias, compared results, and resolved disagreements by consulting a third review author (PL, SA or PP). We contacted investigators for additional data, where possible. We computed the Mantel-Haenszel or inverse variance risk ratio (RR) with 95% confidence interval (CI) for binary outcomes and the mean difference (MD) with 95% CI for continuous variables.

MAIN RESULTS

In this updated review, 16 studies met the inclusion criteria; five were studies of contraceptive implants (715 participants) and 11 were studies of IUDs (1894 participants). We identified 12 ongoing studies. We applied GRADE judgements to our results; the overall certainty of the evidence for each outcome ranged from moderate to very low, with the main limitations being risk of bias, inconsistency, and imprecision. Contraceptive implants Immediate insertion probably improves the initiation rate for contraceptive implants compared with delayed insertion (RR 1.48, 95% CI 1.11 to 1.98; 5 studies, 715 participants; I2 = 95%; moderate-certainty evidence). We are uncertain if there was a difference between the two groups for the utilization rate of contraceptive implants at six months after delivery (RR 1.16, 95% CI 0.90 to 1.50; 3 studies, 330 participants; I2 = 89%; very low-certainty evidence) or at 12 months after insertion (RR 0.98, 95% CI 0.93 to 1.04; 2 studies, 164 participants; I2 = 0%; very low-certainty evidence). People who received an immediate postpartum contraceptive implant insertion may have had a higher mean number of days of prolonged vaginal bleeding within six weeks postpartum (mean difference (MD) 2.98 days, 95% CI -2.71 to 8.66; 2 studies, 420 participants; I2 = 91%; low-certainty evidence) and a higher rate of other adverse effects in the first six weeks after birth (RR 2.06, 95% CI 1.38 to 3.06; 1 study, 215 participants; low-certainty evidence) than those who received a delayed postpartum insertion. We are uncertain if there was a difference between the two groups for prolonged bleeding at six months after delivery (RR 1.19, 95% CI 0.29 to 4.94; 2 studies, 252 participants; I2 = 0%; very low-certainty evidence). There may be little or no difference between the two groups for rates of unintended pregnancy at six months (RR 0.20, 95% CI 0.01 to 4.08; one study, 205 participants; low-certainty evidence). We are uncertain whether there was a difference in rates of unintended pregnancy at 12 months postpartum (RR 1.82, 95% CI 0.38 to 8.71; 1 study, 64 participants; very low-certainty evidence). There may be little or no difference between the two groups for any breastfeeding rates at six months (RR 0.97, 95% CI 0.92 to 1.01; 2 studies, 225 participants; I2 = 48%; low-certainty evidence). IUDs Immediate insertion of IUDs probably improves the initiation rate compared with delayed insertion, regardless of type of IUD (RR 1.27, 95% CI 1.07 to 1.51; 10 studies, 1894 participants; I2 = 98%; moderate-certainty evidence). However, people who received an immediate postpartum IUD insertion may have had a higher expulsion rate at six months after delivery (RR 4.55, 95% CI 2.52 to 8.19; 8 studies, 1206 participants; I2 = 31%; low-certainty evidence) than those who received a delayed postpartum insertion. We are uncertain if there was a difference between the two groups in the utilization of IUDs at six months after insertion (RR 1.02, 95% CI 0.65 to 1.62; 6 studies, 971 participants; I2 = 96%; very low-certainty evidence) or at 12 months after insertion (RR 0.86, 95% CI 0.5 to 1.47; 3 studies, 796 participants; I2 = 92%; very low-certainty evidence). Immediate IUDs insertion may reduce unintended pregnancy at 12 months (RR 0.26, 95% CI 0.17 to 0.41; 1 study, 1000 participants; low-certainty evidence). We are uncertain whether there was difference in any breastfeeding rates at six months in people receiving progestin-releasing IUDs (RR 0.90, 95% CI 0.63 to 1.30; 5 studies, 435 participants; I2 = 54%; very low-certainty evidence).

AUTHORS' CONCLUSIONS

Evidence from this updated review indicates that immediate postpartum insertion improves the initiation rate of both contraceptive implants and IUDs by the first postpartum visit compared to delayed insertion. However, it is not clear whether that there are differences in utilization rates at six and 12 months postpartum. We are uncertain whether there is any difference in the unintended pregnancy rate at 12 months. Provision of progestin-releasing implants and IUDs immediately postpartum may have little or no negative impact on breastfeeding. However, the expulsion rate of IUDs and prolonged vaginal bleeding associated with immediate implants appears to be higher.

Patient acceptability, continuation and complication rates with immediate postpartum levonorgestrel intrauterine device insertion at caesarean section and vaginal birth

BACKGROUND

Immediate postpartum long-acting reversible contraception (LARC) has been shown to reduce unintended pregnancy but uptake of this type of contraception in Australia is low compared to European counterparts.

AIMS

To assess self-reported continuation rates, complications and satisfaction in patients having immediate postpartum hormonal intrauterine device (IUD) inserted at caesarean section (CS) or after vaginal birth (VB).

MATERIALS AND METHODS

Retrospective cohort study of all patients with immediate postpartum hormonal IUD insertion over three years at a tertiary maternity service. Primary outcomes were patient satisfaction, continuation and expulsion rates. Secondary outcomes were reason for discontinuation, patient-reported complications, attendance for postpartum check with a general practitioner (GP) and rate of unplanned pregnancy. Simple descriptive statistics were used to analyse the data.

RESULTS

One hundred and ninety-three women had a hormonal IUD inserted and 143 consented to involvement (CS n = 79; VB n = 64). Six and 12 months continuation rates for CS were 60.8% and 54.4%, and VB were 46.9% and 39.1%. The most common reasons for removal were: pain (34.5%), heavy or irregular bleeding (25.9%) and partial expulsion (24.1%). Expulsion was more likely after VB (34.1%) than CS (10.1%), (odds ratio 2.72; 95% CI 1.07-6.90; P = 0.036). There were 60.8% of women post-CS and 56.3% of women post-VB who were satisfied with their decision to have immediate postpartum insertion and most women attended routine postpartum follow-up with their GP (89.5%).

CONCLUSION

Immediate postpartum hormonal IUD insertion in this cohort is associated with higher rates of expulsion and lower satisfaction rates compared to those documented in the literature for delayed postpartum insertion cohorts.

Etonogestrel Implant in the Postpartum Period and its Impact on Biochemical Markers in Secretory Activation: A Pilot Study

BACKGROUND

Secretory activation is characterized biochemically in human milk by a fall in sodium concentration, an increase in potassium concentration, and a decreased sodium to potassium ratio. These markers can be used to identify a delay in secretory activation which can result from hormonal birth control.

RESEARCH AIM

To evaluate if the insertion of the Etonogestrel implant early in the postpartum period would delay the time to secretory activation as measured by biochemical markers.

METHODS

We conducted a prospective, longitudinal, non-randomized, observational cohort study. Women with singleton pregnancies were identified as wanting either no birth control or the Etonogestrel implant in the postpartum period. Human milk samples were collected starting at 12 hours after delivery, and then in 12-hour increments. Samples were tested for sodium and potassium levels.

RESULTS

As in the unadjusted models, there was evidence of a difference in sodium levels at two days postpartum, with the sodium level higher by 32.29 mM (95% CI [7.39, 57.20], p = .013) in the implant group than in the no birth control method group. A difference at day 2 was observed in the ratio (sodium/potassium) levels, with a higher mean ratio in the implant group by 2.49 (95% CI [0.14, 4.85], p = .039). For potassium levels, the only difference was observed at day 4, with lower values in the implant group (p = .045).

CONCLUSION

The transition from colostrum to copious milk secretion is delayed by the early insertion of the Etonogestrel device. This is evidenced by the delay in biochemical markers normally seen in secretory activation.

Safety and Benefits of Contraceptives Implants: A Systematic Review

Progestin-only contraceptive implants provide long-acting, highly effective reversible contraception. We searched the medical publications in PubMed, CENTRAL, and EMBASE for relevant articles on hormonal implants published in English between 1990 and 2021. Levonorgestrel (LNG) 6-capsule subdermal implants represented the first effective system approved for reversible contraception. The etonogestrel (ENG) single rod dispositive has been widely employed in clinical practice, since it is a highly effective and safe contraceptive method. Abnormal menstrual bleeding is a common ENG side effect, representing the main reason for its premature discontinuation. Emerging evidence demonstrated that it is possible to extend the use of the ENG implant beyond the three-year period for which it is approved. The ENG implant could be an effective and discrete alternative to the IUD in young girls, such as post-partum/post-abortion. Implants should be inserted by trained skilled clinicians who previously provide adequate counselling about their contraceptive effect, benefits, and any possible adverse events. More studies are needed to validate the extended use of the ENG implant for up to 5 years.

Comparison of levonorgestrel level and creamatocrit in milk following immediate versus delayed postpartum placement of the levonorgestrel IUD

BACKGROUND

Breastfeeding and postpartum contraception critically influence infant and maternal health outcomes. In this pilot study, we explore the effects of timing and duration of postpartum levonorgestrel exposure on milk lipid and levonorgestrel content to establish baseline data for future research.

METHODS

This sub-study recruited a balanced convenience sample from 259 participants enrolled in a parent randomized controlled trial comparing immediate to delayed (4-8 weeks) postpartum levonorgestrel IUD placement. All planned to breastfeed, self-selected for sub-study participation, and provided the first sample at 4-8 weeks postpartum (before IUD placement for the delayed group) and the second four weeks later. We used the Wilcoxon rank sum (inter-group) and signed rank (intra-group) tests to compare milk lipid content (creamatocrit) and levonorgestrel levels between groups and time points.

RESULTS

We recruited 15 participants from the immediate group and 17 from the delayed group with 10 and 12, respectively, providing both early and late samples. Initially, median levonorgestrel concentration of the immediate group (n = 10) (32.5 pg/mL, IQR: 24.8, 59.4) exceeded that of the delayed group (n = 12) (17.5 pg/mL, IQR: 0.0, 25.8) (p = 0.01). Four weeks later, the values aligned: 26.2 pg/mL (IQR: 20.3, 37.3) vs. 28.0 pg/mL (IQR: 25.2, 40.8). Creamatocrits were similar between both groups and timepoints.

CONCLUSIONS

Immediate postpartum levonorgestrel IUD placement results in steady, low levels of levonorgestrel in milk without apparent effects on lipid content. These findings provide initial support for the safety of immediate postpartum levonorgestrel IUD initiation, though the study was not powered to detect noninferiority between groups.

Factors Affecting Contraception Access and Use in Patients With Opioid Use Disorder

Maternal opioid use disorder increased > 4-fold from 1999 to 2014 and is associated with poor maternal and fetal outcomes. Women with opioid use disorder are at 2 to 3 times greater risk for unintended pregnancy than the general population and may face additional barriers to accessing and effectively using contraception compared to women without opioid use disorder, particularly highly effective long-acting reversible contraception. Additionally, women with opioid use disorder tend to use less effective forms of contraception such as condoms alone. Barriers to contraceptive access include patient misconceptions or knowledge gaps regarding reproductive health and family planning, cost, intimate partner violence, fear of criminalization, difficulty accessing care, comorbid health conditions, and health care provider misconceptions or practice limitations. Strategies that may assist women with opioid use disorder in achieving their family planning goals include colocation of family planning services within opioid treatment facilities, optimization of patient care services to minimize the need for costly and/or time consuming follow-up, increasing provider education and awareness of best practices in family planning and opioid use disorder treatment, and providing patient-centered family planning education and counseling. Additional research is needed to identify and develop strategies that empower women who use opioids to effectively access and use their preferred contraceptive method.

Expulsion rate of intrauterine device: mediate vs. immediate puerperium period

Objective

To evaluate the rate of expulsion of intrauterine device (IUD) inserted during the immediate and mediate puerperium. To evaluate whether the type of delivery is a predictor of expulsion of the IUD when inserted in the puerperium period.

Material and Methods

This was a prospective observational study. Patients whose IUD (TCU-380 copper) was placed during the puerperal period were divided in two groups according to the time of placement: immediate and mediate puerperium. The decision regarding the time of IUD insertion was made in a non-randomized manner. Analysis was performed using chi-square, Mann-Whitney U, and Spearman’s correlation tests and logistic regression analysis.

Results

The total rate of IUD expulsions was 28.8% (49/170). There was no significant association between the occurrence of expulsion and the timing of IUD insertion (immediate vs mediate puerperium; 26.6% vs 34.78%, p=0.296). Among patients experiencing expulsion, 79.6% (39/49) underwent insertion after vaginal delivery and 20.4% (10/49) during cesarean section (CS). The type of delivery was a significant predictor for IUD expulsion (p<0.0001). Vaginal delivery was fourfold more likely to be associated with IUD expulsion inserted in the puerperal period than CS (odds ratio: 4.23, 95% confidence interval: 1.94-9.25). There was no significant correlation between the period between IUD insertion and the diagnosis of expulsion in regard to number of pregnancies (r=-0.160, p=0.271) or gestational age at delivery (r=-0.058, p=0.939).

Conclusion

Vaginal delivery was the most prevalent type of delivery in patients who underwent IUD insertion during the immediate and mediate puerperium. The risk of IUD expulsion after vaginal delivery was greater than CS.

Risk of abortion within 1-2 years after childbirth in relation to contraceptive choice: a retrospective cohort study

Objectives: The primary objective of the study was to investigate whether the choice of long-acting reversible contraception (LARC) was associated with the risk of abortion over a period of 24 months postpartum. The secondary objective was to analyse whether other significant factors were affecting the risk of abortion during this period.Methods: In this retrospective cohort study, we analysed 11,066 women who had delivered in three Swedish cities during 2013 and 2014. Demographic and medical variables were obtained from medical records. Attendance at the postpartum visit, choice of postpartum contraception and history of abortion was noted. Logistic regression analysis was performed to assess factors associated with the risk of abortion. The main outcome measure was the proportion of women with abortion up to 24 months postpartum.Results: Data from 11,066 women were included in the final analysis. Within 12-24 months after delivery 2.5% of women had an abortion. The choice of LARC after childbirth reduced the risk of subsequent abortion (odds ratio 0.74; 95% confidence interval [CI] 0.60, 0.91; p =  .005). Smoking, age <25 years and have had a previous abortion significantly increased the risk of abortion during follow-up, whereas exclusive breastfeeding decreased the risk.Conclusions: Increasing the proportion of women who choose LARC postpartum could decrease the risk of abortion for up to 2 years after childbirth.

Priorities for Contraception and Lactation Among Breast Pump-Dependent Mothers of Premature Infants in the Neonatal Intensive Care Unit

Objective: Determine the knowledge and priorities for postpartum contraception and lactation in mothers of premature infants. Design: Twenty-five mothers of premature infants (mean gestational age = 29.9 weeks) hospitalized in a tertiary neonatal intensive care unit (NICU) participated in a multi-methods study using a multiple-choice contraceptive survey and qualitative interview in the first 2 weeks postpartum. Data were analyzed using content analysis and descriptive statistics. Results: Although 60% of mothers planned to use contraception, all questioned the timing of postpartum contraceptive counseling while recovering from a traumatic birth and coping with the critical health status of the infant. All mothers prioritized providing mothers' own milk (MOM) over the use of early hormonal contraception because they did not want to "take any risks" with their milk. They had limited knowledge of risks for repeat preterm birth (e.g., prior preterm birth: n = 13, 52%; multiple birth: n = 9, 36%; no knowledge: n = 3, 12%); only two mothers (0.08%) were counseled about the risks of a short interpregnancy interval. Conclusion: The context of the infants' NICU admission and the mother's desire to "do what is best for the baby" by prioritizing MOM should be integrated into postpartum contraceptive counseling for this population.

Timing of postpartum etonogestrel-releasing implant insertion and bleeding patterns, weight change, 12-month continuation and satisfaction rates: a randomized controlled trial

OBJECTIVES

To evaluate whether timing of etonogestrel (ENG) implant insertion during the postpartum period affects maternal bleeding patterns, body mass index (BMI) and 12-month satisfaction and continuation rates.

STUDY DESIGN

This is a secondary analysis of an open, randomized, controlled trial. Postpartum women were block-randomized to early (up to 48 h postpartum) or delayed (6 weeks postpartum) insertion of an ENG implant. Bleeding patterns and BMI were evaluated every 90 days for 12 months. At 12 months, we measured implant continuation rates and used Likert and face scales to measure users' satisfaction. The level of significance was 0.4% (adjusted by Bonferroni test for multiplicity).

RESULTS

We enrolled 100 postpartum women; we randomized 50 to early and 50 to delayed postpartum ENG implant insertion. Bleeding patterns were similar between groups. Amenorrhea rates were high in both groups during the follow-up (52%-56% and 46%-62% in the early and delayed insertion group, respectively). Prolonged bleeding episodes were unusual in both groups during the follow-up (0-2%). Maternal BMI was similar between groups and decreased over time. Twelve-month continuation rates were similar between groups (early insertion: 98% vs. delayed insertion: 100%, p=.99). Most participants were either very satisfied or satisfied with the ENG implant in both groups (p=.9).

CONCLUSION

Women who underwent immediate postpartum insertion of the ENG implant have similar bleeding patterns, BMI changes, and 12-month satisfaction and continuation rates compared to those who underwent delayed insertion.

IMPLICATIONS

Our results from a secondary analysis of a clinical trial support that satisfaction, continuation and bleeding patterns do not differ when women received contraceptive implants immediately postpartum or at 6 weeks. However, the emphasis on infant growth in the trial and easy access to delayed placement may have influenced results.

Society for Maternal-Fetal Medicine (SMFM) Consult Series #48: Immediate postpartum long-acting reversible contraception for women at high risk for medical complications

Reproductive planning is essential for all women and most important for those with complex health conditions or at high risk for complications. Pregnancy planning can allow these high-risk women the opportunity to receive preconception counseling, medication adjustment, and risk assessment related to health conditions that have a direct impact on maternal morbidity and mortality risk. Despite the need for pregnancy planning, medically complex women face barriers to contraceptive use, including systemic barriers, such as underinsurance for women at increased risk for complex medical conditions as well as low uptake of effective postpartum contraception. Providing contraceptive counseling and a full range of contraceptive options, including immediate postpartum long-acting reversible contraception (LARC), is a means of overcoming these barriers. The purpose of this document is to educate all providers, including maternal-fetal medicine subspecialists, about the benefits of postpartum contraception, and to advocate for widespread implementation of immediate postpartum LARC placement programs. The following are Society for Maternal-Fetal Medicine recommendations: we recommend that LARC be offered to women at highest risk for adverse health events as a result of a future pregnancy (GRADE 1B); we recommend that obstetric care providers discuss the availability of immediate postpartum LARC with all pregnant women during prenatal care and consult the U.S. Medical Eligibility Criteria for Contraceptive Use guidelines to determine methods most appropriate for specific medical conditions (GRADE 1C); we recommend that women considering immediate postpartum intrauterine device insertion be counseled that although expulsion rates are higher than with delayed insertion, the benefits appear to outweigh the risk of expulsion, as the long-term continuation rates are higher (GRADE 1C); we recommend that obstetric care providers wishing to utilize immediate postpartum LARC obtain training specific to the immediate postpartum period (BEST PRACTICE); for women who desire and are eligible for LARC, we recommend immediate postpartum placement after a high-risk pregnancy over delayed placement due to overall superior efficacy and cost-effectiveness (GRADE 1B); we recommend that women considering immediate postpartum LARC be encouraged to breastfeed, as current evidence suggests that these methods do not negatively influence lactation (GRADE 1B); for women who desire and are eligible for LARC, we suggest that early postpartum LARC placement be considered when immediate postpartum LARC placement is not feasible (GRADE 2C); and we recommend that contraceptive counseling programs be patient-centered and provided in a shared decision-making framework to avoid coercion (BEST PRACTICE).

A Comparison of Breastfeeding Exclusivity and Duration Rates Between Immediate Postpartum Levonorgestrel Versus Etonogestrel Implant Users: A Prospective Cohort Study

OBJECTIVE

This study compares breastfeeding outcomes after immediate postpartum initiation of single-rod etonogestrel (ENG) versus two-rod levonorgestrel (LNG) contraceptive implants. Outcomes assessed include the following: (1) breastfeeding continuation through 24 months after delivery and (2) exclusive breastfeeding until 6 months after delivery, at Kasungu District Hospital, Malawi.

METHODS

We used Kaplan-Meier survival analysis to compare breastfeeding continuation through 24 months and exclusive breastfeeding through 6 months after delivery for ENG versus LNG implant users. We described infant feeding practices up to 6 months after delivery.

RESULTS

We analyzed 140 women: 28 (20%) ENG and 112 (80%) LNG impalnt users. Eighty-seven percent (n = 122) of women completed the 24-month study visit. Twenty-four months breastfeeding continuation proportions were 54.2% (95% confidence interval [CI] = 32.7-71.4) and 74.7% (95% CI = 64.9-82.2) for ENG and LNG implant users, respectively (p = 0.10). Breastfeeding continuation was high in both groups at 21 months: 100% and 93.2% (95% CI = 86.2-96.7) for ENG and LNG implant users, respectively (p = 0.18). Seventy-one percent (20/28, 95% CI = 51.0-84.6) of ENG and 72% (78/108, 95% CI = 62.4-79.7) of LNG implant users exclusively breastfed their infants until 6 months postpartum (p = 0.89).

CONCLUSIONS

Continuation of breastfeeding until 24 months and exclusive breastfeeding until 6 months were high among users of both types of progestin implant initiated immediately postpartum and similar to proportions among the general population of postpartum women in the Central region of Malawi.

Hormonal contraception, breastfeeding and bedside advocacy: the case for patient-centered care

Postpartum contraceptive decision making is complex, and recommendations may be influenced by breastfeeding intentions. While biologically plausible, concerns about the adverse impact of hormonal contraception on breast milk production have not been supported by the clinical evidence to date. However, the data have limitations, which can lead providers with different priorities around contraception and breastfeeding to interpret the data in a way that advances their personal priorities. Discrepancies in interpretations can lead to divergent recommendations for individual women and may cause conflict. Furthermore, providers must recognize that decision making about contraception and breastfeeding takes place in complex cultural, historical and socioeconomic contexts. Implicit bias may influence a provider's counseling. Unrecognized biases toward one patient or another, or one practice or another, may influence a provider's counseling. It is crucial for providers to strive to recognize their own biases. Providers need to respectfully recognize each patient's values and preferences regarding hormonal contraception and breastfeeding. Developing a patient-centered decision tool or implementing patient-centered interview techniques specifically around breastfeeding and contraception could help to minimize provider-driven variability in care.

The effect of immediate postpartum levonorgestrel contraceptive implant use on breastfeeding and infant growth: a randomized controlled trial

OBJECTIVE

This study assessed whether immediate postpartum insertion of levonorgestrel contraceptive implants is associated with a difference in infant growth from birth to 6 months, onset of lactogenesis, or breastfeeding continuation at 3 and 6 months postpartum compared to delayed insertion at 6 to 8 weeks postpartum.

STUDY DESIGN

We conducted a randomized trial of women in Uganda who desired contraceptive implants postpartum. We randomly assigned participants to receive either immediate (within 5 days of delivery) or delayed (6 to 8 weeks postpartum) insertion of a two-rod levonorgestrel contraceptive implant system. This is a prespecified secondary analysis evaluating breastfeeding outcomes. The primary outcome of this secondary analysis was change in infant weight; infants were weighed and measured at birth and 6 months. We used a validated questionnaire to assess onset of lactogenesis daily in person while participants were in the hospital, and then daily by phone after they left the hospital, until lactogenesis was documented. We used interviewer-administered questionnaires to assess breastfeeding continuation and concerns at 3 months and 6 months postpartum.

RESULTS

Among the 96 women randomized to the immediate group and the 87 women to the delayed group, the mean change in infant weight from birth to 6 months was similar between groups: 4632 g in the immediate group and 4407 g in the delayed group (p=.26). Among the 97 women who had not experienced lactogenesis prior to randomization, the median time to onset of lactogenesis did not differ significantly between the immediate and delayed groups (65 h versus 63 h; p=.84). Similar proportions of women in the immediate and delayed groups reported exclusive breastfeeding at 3 months (74% versus 71%; p=.74) and 6 months (48% versus 52%; p=.58).

CONCLUSION

We found no association between the timing of postpartum initiation of levonorgestrel contraceptive implants and change in infant growth from birth to 6 months, onset of lactogenesis, or breastfeeding continuation at 3 or 6 months postpartum.

IMPLICATIONS

This study provides evidence that immediate postpartum initiation of contraception implants does not have a deleterious effect on infant growth or initiation or continuation of breastfeeding.

Immediate postpartum levonorgestrel intrauterine device insertion and breast-feeding outcomes: a noninferiority randomized controlled trial

BACKGROUND

Immediate postpartum levonorgestrel intrauterine device insertion is increasing in frequency in the United States, but few studies have investigated the effect of early placement on breast-feeding outcomes.

OBJECTIVE

This study examined the effect of immediate vs delayed postpartum levonorgestrel intrauterine device insertion on breast-feeding outcomes.

STUDY DESIGN

We conducted this noninferiority randomized controlled trial at the University of Utah and the University of New Mexico Health Sciences Centers from February 2014 through March 2016. Eligible women were pregnant and planned to breast-feed, spoke English or Spanish, were aged 18-40 years, and desired a levonorgestrel intrauterine device. Enrolled women were randomized 1:1 to immediate postpartum insertion or delayed insertion at 4-12 weeks' postpartum. Prespecified exclusion criteria included delivery <37.0 weeks' gestational age, chorioamnionitis, postpartum hemorrhage, contraindications to levonorgestrel intrauterine device insertion, and medical complications of pregnancy that could affect breast-feeding. We conducted per-protocol analysis as the primary approach, as it is considered the standard for noninferiority studies; we also report the alternative intent-to-treat analysis. We powered the study for the primary outcome, breast-feeding continuation at 8 weeks, to detect a 15% noninferiority margin between groups, requiring 132 participants in each arm. The secondary study outcome, time to lactogenesis, used a validated measure, and was analyzed by survival analysis and log rank test. We followed up participants for ongoing data collection for 6 months. Only the data analysis team was blinded to the intervention.

RESULTS

We met the enrollment target with 319 participants, but lost 34 prior to randomization and excluded an additional 26 for medical complications prior to delivery. The final analytic sample included 132 in the immediate group and 127 in the delayed group. Report of any breast-feeding at 8 weeks in the immediate group (79%; 95% confidence interval, 70-86%) was noninferior to that of the delayed group (84%; 95% confidence interval, 76-91%). The 5% difference in breast-feeding continuation at 8 weeks between the groups fell within the noninferiority margin (95% confidence interval, -5.6 to 15%). Time to lactogenesis (mean ± SD) in the immediate group, 65.3 ± 25.7 hours, was noninferior to that of the delayed group, 63.6 ± 21.6 hours. The mean difference between groups was 1.7 hours (95% confidence interval, -4.8 to 8.2 hours), noninferior by log-rank test. A total of 24 intrauterine device expulsions occurred in the immediate group compared to 2 in the delayed group (19% vs 2%, P < .001), consistent with the known higher expulsion rate with immediate vs delayed postpartum intrauterine device insertion. No intrauterine device perforations occurred in either group.

CONCLUSION

Our results of noninferior breast-feeding outcomes between women with immediate and delayed postpartum levonorgestrel intrauterine device insertion suggest that immediate postpartum intrauterine device insertion is an acceptable option for women planning to breast-feed and use the levonorgestrel intrauterine device. Expulsion rates are higher with immediate postpartum levonorgestrel intrauterine device insertion compared to delayed insertion, but this disadvantage may be outweighed by the advantages of immediate initiation of contraception. Providers should offer immediate postpartum intrauterine device insertion to breast-feeding women planning to use the levonorgestrel intrauterine device.

Immediate versus delayed postpartum use of levonorgestrel contraceptive implants: a randomized controlled trial in Uganda

BACKGROUND

Use of long-acting, highly effective contraception has the potential to improve women's ability to avoid short interpregnancy intervals, which are associated with an increased risk of maternal morbidity and mortality, and preterm delivery. In Uganda, contraceptive implants are not routinely available during the immediate postpartum period.

OBJECTIVE

The purpose of this study was to compare the proportion of women using levonorgestrel contraceptive implants at 6 months after delivery in women randomized to immediate or delayed insertion.

STUDY DESIGN

This was a randomized controlled trial among women in Kampala, Uganda. Women who desired contraceptive implants were randomly assigned to insertion of a 2-rod contraceptive implant system containing 75 mg of levonorgestrel immediately following delivery (within 5 days of delivery and before discharge from the hospital) or delayed insertion (6 weeks postpartum). The primary outcome was implant utilization at 6 months postpartum.

RESULTS

From June to October 2015, 205 women were randomized, 103 to the immediate group and 102 to the delayed group. Ninety-three percent completed the 6 month follow-up visit. At 6 months, implant use was higher in the immediate group compared with the delayed group (97% vs 68%; P < .001), as was the use of any highly effective contraceptive (98% vs 81%; P = .001). Women in the immediate group were more satisfied with the timing of implant placement. If given the choice, 81% of women in the immediate group and 63% of women in the delayed group would choose the same timing of placement again (P = .01). There were no serious adverse events in either group.

CONCLUSION

Offering women the option of initiating contraceptive implants in the immediate postpartum period has the potential to increase contraceptive utilization, decrease unwanted pregnancies, prevent short interpregnancy intervals, and help women achieve their reproductive goals.

Practice Bulletin No. 186: Long-Acting Reversible Contraception: Implants and Intrauterine Devices

Intrauterine devices and contraceptive implants, also called long-acting reversible contraceptives (LARC), are the most effective reversible contraceptive methods. The major advantage of LARC compared with other reversible contraceptive methods is that they do not require ongoing effort on the part of the patient for long-term and effective use. In addition, after the device is removed, the return of fertility is rapid (1, 2). The purpose of this Practice Bulletin is to provide information for appropriate patient selection and evidence-based recommendations for LARC initiation and management. The management of clinical challenges associated with LARC use is beyond the scope of this document and is addressed in Committee Opinion No. 672, Clinical Challenges of Long-Acting Reversible Contraceptive Methods (3).

Timing of Etonogestrel-Releasing Implants and Growth of Breastfed Infants: A Randomized Controlled Trial

OBJECTIVE

To evaluate the growth of breastfed infants whose mothers had inserted an etonogestrel-releasing implant in the immediate postpartum period.

METHODS

An open, randomized controlled, and parallel trial of postpartum women who were block-randomized to early (up to 48 hours postpartum before discharge) or conventional (at 6 weeks postpartum) insertion of an etonogestrel implant. The primary outcome was average infant weight at 12 months (360 days) and a difference of equal to or greater than 10% between groups was considered clinically significant. The secondary outcomes were infant's height and head and arm circumferences. These variables were measured at baseline and at 14, 40, 90, 180, 270, and 360 days postpartum. The mixed-effects linear regression model was used to evaluate the outcomes with a power of 80% and a significance level of 1% for the primary outcome and 0.3% for secondary outcomes as a result of correction for multiple hypothesis testing.

RESULTS

From June to August 2015, a total of 100 women were randomized: 50 to early and 50 to conventional postpartum etonogestrel insertion. Sociodemographic characteristics were similar between the groups, except for educational attainment. The conventional insertion group included a higher proportion of women with 8 or more years of formal education than the early insertion group (88% [44/50] compared with 70% [35/50], P=.02). There was no difference in infant weight at 360 days between the groups (early [mean±standard deviation] 10.1±1.2 kg compared with conventional 9.8±1.3 kg, mean difference estimate 0.3 kg, 95% confidence interval 0-0.7 kg). Growth curves, height, and head and arm circumferences did not differ between the groups.

CONCLUSION

There is no difference in growth at 12 months among breastfed infants whose mothers underwent early compared with conventional postpartum insertion of the etonogestrel implant.

Immediate postpartum intrauterine device and implant program outcomes: a prospective analysis

BACKGROUND

In-hospital placement of intrauterine devices and contraceptive implants following vaginal and cesarean delivery is increasingly popular and responds to maternal motivation for highly effective postpartum contraception. Immediate postpartum intrauterine device insertion is associated with higher expulsion than interval placement, but emerging evidence suggests that the levonorgestrel intrauterine device may have a higher expulsion rate than the copper intrauterine device.

OBJECTIVE

This study evaluated in-hospital provision, expulsion, and 6-month continuation of immediate postpartum copper T380 intrauterine devices, levonorgestrel intrauterine devices, and contraceptive implants.

STUDY DESIGN

We offered enrollment in this prospective observational trial to women presenting to the University of Utah labor and delivery unit from October 2013 through February 2016 who requested an intrauterine device or implant for postpartum contraception during prenatal care or hospitalization at the time of delivery. Following informed consent, participants completed questionnaires prior to hospital discharge and at 3 and 6 months postpartum. Data on expulsions at 6 months were validated by chart abstraction.

RESULTS

During the study period, 639 patients requested a postpartum intrauterine device or implant and 350 patients enrolled in prospective follow-up prior to discharge from the hospital. Among enrollees, 325 (93%) received their preferred contraceptive device prior to hospital discharge: 88 (27%) copper intrauterine device users, 123 (38%) levonorgestrel intrauterine device users, and 114 (35%) implant users. Participants predominantly were Hispanic (90%), were multiparous (87%), reported a household income <$24,000 per year (87%), and underwent a vaginal delivery (77%). At 6 months postpartum, 289 of 325 device recipients (89%) completed follow-up. Among levonorgestrel intrauterine device users 17% reported expulsions relative to 4% of copper intrauterine device users. The adjusted hazard ratio for expulsion was 5.8 (confidence interval, 1.3-26.4). There was no statistically significant difference in expulsions by delivery type or continuation by device type. Among the 21 women who experienced intrauterine device expulsions, 14 (67%) requested a replacement long-acting reversible contraception device for contraception. The 6-month device continuation was ≥80% for all device types.

CONCLUSION

An immediate postpartum long-acting reversible contraception program effectively provides women who desire highly effective reversible contraceptive devices with their method of choice prior to hospital discharge. Immediate postplacental levonorgestrel intrauterine device users have higher expulsion rates than copper intrauterine device users, but >8 of 10 women initiating an intrauterine device or implant continue use at 6 months postpartum.

Committee Opinion No. 670: Immediate Postpartum Long-Acting Reversible Contraception

Immediate postpartum long-acting reversible contraception (LARC) has the potential to reduce unintended and short-interval pregnancy. Women should be counseled about all forms of postpartum contraception in a context that allows informed decision making. Immediate postpartum LARC should be offered as an effective option for postpartum contraception; there are few contraindications to postpartum intrauterine devices and implants. Obstetrician-gynecologists and other obstetric care providers should discuss LARC during the antepartum period and counsel all pregnant women about options for immediate postpartum initiation. Education and institutional protocols are needed to raise clinician awareness and to improve access to immediate postpartum LARC insertion. Obstetrician-gynecologists and other obstetric care providers should incorporate immediate postpartum LARC into their practices, counsel women appropriately about advantages and risks, and advocate for institutional and payment policy changes to support provision.

Etonogestrel-Releasing Contraceptive Implant for Postpartum Adolescents: A Randomized Controlled Trial

STUDY OBJECTIVE

To compare immediate postpartum insertion of the contraceptive implant to placement at the 6-week postpartum visit among adolescent and young women.

DESIGN

Non-blinded, randomized controlled trial.

SETTING AND PARTICIPANTS

Postpartum adolescents and young women ages 14-24 years who delivered at an academic tertiary care hospital serving rural and urban populations in North Carolina.

INTERVENTIONS

Placement of an etonogestrel-releasing contraceptive implant before leaving the hospital postpartum, or at the 4-6 week postpartum visit.

MAIN OUTCOME MEASURES

Contraceptive implant use at 12 months postpartum.

RESULTS

Ninety-six participants were randomized into the trial. Data regarding use at 12 months were available for 64 participants, 37 in the immediate group and 27 in the 6-week group. There was no difference in use at 12 months between the immediate group and the 6-week group (30 of 37, 81% vs 21 of 27, 78%; P = .75). At 3 months, the immediate group was more likely to have the implant in place (34 of 37, 92% vs 19 of 27, 70%; P = .02).

CONCLUSION

Placing the contraceptive implant in the immediate postpartum period results in a higher rate of use at 3 months postpartum and appears to have similar use rates at 12 months compared with 6-week postpartum placement. Providing contraceptive implants to adolescents before hospital discharge takes advantage of access to care, increases the likelihood of effective contraception in the early postpartum period, appears to have no adverse effects on breastfeeding, and might lead to increased utilization at 1 year postpartum.

Immediate versus delayed postpartum insertion of contraceptive implant for contraception

BACKGROUND

The spacing of pregnancies has a positive impact on maternal and newborn health. The progestin contraceptive implant, which is a long-acting, reversible method of contraception, has a well-established low failure rate that is compatible with tubal sterilization. The standard provision of contraceptive methods on the first postpartum visit may put some women at risk of unintended pregnancy, either due to loss to follow-up or having sexual intercourse prior to receiving contraception. Therefore, the immediate administration of contraception prior to discharge from the hospital that has high efficacy may improve contraceptive prevalence and prevent unintended pregnancy.

OBJECTIVES

To compare the initiation rate, effectiveness, and side effects of immediate versus delayed postpartum insertion of implant for contraception.

SEARCH METHODS

We searched for eligible studies up to 28 October 2016 in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and POPLINE. We examined review articles and contacted investigators. We also checked registers of ongoing clinical trials, citation lists of included studies, key textbooks, grey literature, and previous systematic reviews for potentially relevant studies.

SELECTION CRITERIA

We sought randomised controlled trials (RCTs) that compared immediate postpartum versus delayed insertion of contraceptive implant for contraception.

DATA COLLECTION AND ANALYSIS

Two review authors (JS, YW) independently screened titles and abstracts of the search results, and assessed the full-text articles of potentially relevant studies for inclusion. They extracted data from the included studies, assessed risk of bias, compared results, and resolved disagreements by consulting a third review author (PL or SK). We contacted investigators for additional data, where possible. We computed the Mantel-Haenszel risk ratio (RR) with 95% confidence interval (CI) for binary outcomes and the mean difference (MD) with 95% CI for continuous variables.

MAIN RESULTS

Three studies that included 410 participants met the inclusion criteria of the review. We did not identify any ongoing trials. Two included studies were at low risk of selection, attrition, and reporting biases, but were at high risk of performance and detection biases due to the inability to blind participants to the intervention. One included study was at high risk of attrition bias. The overall quality of the evidence for each comparison ranged from very low to moderate; the main limitations were risk of bias and imprecision.Initiation rate of contraceptive implants at the first postpartum check-up visit was significantly higher in the immediate insertion group than in the delayed insertion group (RR 1.41, 95% CI 1.28 to 1.55; three studies, 410 participants; moderate quality evidence).There appeared to be little or no difference between the groups in the continuation rate of contraceptive implant used at six months after insertion (RR 1.02, 95% CI 0.93 to 1.11; two studies, 125 participants; low quality evidence) or at 12 months after insertion (RR 1.04; 95% CI 0.81 to 1.34; one study, 64 participants;very low quality evidence)Women who received an immediate postpartum contraceptive implant insertion had a higher mean number of days of abnormal vaginal bleeding within six weeks postpartum (MD 5.80 days, 95% CI 3.79 to 7.81; one study, 215 participants; low quality evidence) and a higher rate of other side effects in the first six weeks after birth (RR 2.06, 95% CI 1.38 to 3.06; one study, 215 participants; low quality evidence) than those who received a delayed postpartum insertion. There appeared to be little or no difference between the groups in heavy, irregular vaginal bleeding or associated severe cramping within 12 months (RR 1.01, 95% CI 0.72 to 1.44, one study, 64 participants;very low quality evidence).It was unclear whether there was any difference between the groups in scores for participant satisfaction on a 0-10 scale (MD -0.40, 95% CI -1.26 to 0.46, low quality evidence), or in rates of unintended pregnancy (RR 1.82, 95% CI 0.38 to 8.71, 1 RCT, 64 women, very low quality evidence) at 12 months, or in rate of breastfeeding rate at six months (RR 2.01, 95% CI 0.72 ro 5.63, 1 RCT, 64 women, very low quality evidence) rate did not differ significantly between the groups.

AUTHORS' CONCLUSIONS

Evidence from this review indicates that the rate of initiation of contraceptive implant at the first postpartum check-up visit was higher with immediate postpartum insertion than with delayed insertion. There appeared to be little or no difference between the groups in the continuation rate of contraceptive implant use at 6 months. It was unclear whether there was any difference between the groups in continuation of contraceptive use at 12 months or in the unintended pregnancy rate at 12 months.

Optimizing maternal and neonatal outcomes with postpartum contraception: impact on breastfeeding and birth spacing

Postpartum contraception is important to prevent unintended pregnancies. Assisting women in achieving recommended inter-pregnancy intervals is a significant maternal-child health concern. Short inter-pregnancy intervals are associated with negative perinatal, neonatal, infant, and maternal health outcomes. More than 30% of women experience inter-pregnancy intervals of less than 18 months in the United States. Provision of any contraceptive method after giving birth is associated with improved inter-pregnancy intervals. However, concerns about the impact of hormonal contraceptives on breastfeeding and infant health have limited recommendations for such methods and have led to discrepant recommendations by organizations such as the World Health Organization and the U.S. Centers for Disease Control and Prevention. In this review, we discuss current recommendations for the use of hormonal contraception in the postpartum period. We also discuss details of the lactational amenorrhea method and effects of hormonal contraception on breastfeeding. Given the paucity of high quality evidence on the impact on hormonal contraception on breastfeeding outcomes, and the strong evidence for improved health outcomes with achievement of recommended birth spacing intervals, the real risk of unintended pregnancy and its consequences must not be neglected for fear of theoretical neonatal risks. Women should establish desired hormonal contraception before the risk of pregnancy resumes. With optimization of postpartum contraception provision, we will step closer toward a healthcare system with fewer unintended pregnancies and improved birth outcomes.

New developments in long-acting reversible contraception: the promise of intrauterine devices and implants to improve family planning services

After decades of having the developed world's highest rates of unintended pregnancy, the United States finally shows signs of improvement. This progress is likely due in large part to increased use of highly effective long-acting reversible methods of contraception. These methods can be placed and do not require any maintenance to provide years of contraception as effective as sterilization. Upon removal, fertility returns to baseline rates. This article addresses advances in both software-improved use and elimination of barriers to provide these methods; and hardware-novel delivery systems and devices.

Progestogen-only contraceptive use among breastfeeding women: a systematic review

BACKGROUND

Postpartum women need effective contraception. Concerns have been raised that use of progestogen-only contraceptives (POCs) may affect breastfeeding performance and infant health outcomes.

OBJECTIVES

We investigated the clinical outcomes of breastfeeding duration, initiation of supplemental feeding and weaning, as well as infant outcomes including infant growth, health and development among breastfeeding women using POCs compared with breastfeeding women not using POCs.

SEARCH STRATEGY

We searched the PubMed database for all articles published from database inception through December 2014.

SELECTION CRITERIA

We included primary research studies of breastfeeding women of any age or parity who received POCs, including progestogen-only pills, injectables, implants or hormonal intrauterine devices (IUDs). The main outcomes were breastfeeding performance (as measured by initiation, continuation, frequency and exclusivity of breastfeeding) and infant health (as measured by growth, development or adverse health effects).

RESULTS

Forty-nine articles reporting on 47 different studies were identified that investigated the use of POCs in breastfeeding women and reported clinically relevant outcomes of infant growth, health or breastfeeding performance. Studies ranged from poor to fair methodological quality and generally failed to show negative effects of the use of POCs on breastfeeding outcomes or on infant growth or development. One randomized controlled trial (RCT) raises concerns that immediate insertion of the levonorgestrel IUD postpartum may be associated with poorer breastfeeding performance when compared with delayed insertion, although two other RCTs evaluating early etonogestrel implants compared with delayed initiation of implants or depot medroxyprogesterone acetate failed to find such an association.

CONCLUSION

The preponderance of evidence fails to demonstrate adverse breastfeeding outcomes or negative health outcomes in infants such as restricted growth, health problems or impaired development. Evidence newly added to this review was largely consistent with previous evidence.

Association of Etonogestrel-Releasing Contraceptive Implant with Reduced Weight Gain in an Exclusively Breastfed Infant: Report and Literature Review

BACKGROUND

Studies have not found that hormonal contraceptive implants adversely affect breastfeeding, but theoretical concerns exist.

METHODS

We reported a case of reduced weight gain in an exclusively breastfed infant in association with placement of (ENG)-releasing contraceptive implant (Nexplanon) to the FDA Adverse Events Reporting System (FAERS). We further queried reports to FAERS and reviewed published studies of the ENG implant during breastfeeding.

RESULTS

A breastfeeding mother received an ENG implant at 4 weeks postpartum. Her infant was exclusively breastfeeding. One month after implant placement, the infant had lost 145 g, dropping from the 44th percentile to the 6th percentile for growth. During this period, the mother had not returned to work or decreased frequency of feeding. During a 2-year period of FAERS reports, we found one other report of reduced milk supply following ENG implant placement. Among 108 breastfeeding women studied while using the ENG implant, there was one case of lactation failure. If this were not due to chance, the estimated risk of lactation failure with the ENG implant would be 0.9% (95% confidence interval 0.2-5.1%).

CONCLUSION

Given uncertainty regarding the true effect of ENG implants on lactation, it seems prudent for providers to counsel each woman about a possible effect on milk supply so that she can monitor her infant for signs of impaired milk transfer. Patient-centered counseling approaches are needed that allow each woman to assess her own individual tolerance of risk of unplanned pregnancy versus possible risk of lactation failure.

Canadian Contraception Consensus (Part 3 of 4): Chapter 8 - Progestin-Only Contraception

OBJECTIVE

To provide guidelines for health care providers on the use of contraceptive methods to prevent pregnancy and on the promotion of healthy sexuality.

OUTCOMES

Overall efficacy of cited contraceptive methods, assessing reduction in pregnancy rate, safety, ease of use, and side effects; the effect of cited contraceptive methods on sexual health and general well-being; and the relative cost and availability of cited contraceptive methods in Canada.

EVIDENCE

Published literature was retrieved through searches of Medline and The Cochrane Database from January 1994 to January 2015 using appropriate controlled vocabulary (e.g., contraception, sexuality, sexual health) and key words (e.g., contraception, family planning, hormonal contraception, emergency contraception). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English from January 1994 to January 2015. Searches were updated on a regular basis in incorporated in the guideline to June 2015. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

VALUES

The quality of the evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). CHAPTER 8: PROGESTIN-ONLY CONTRACEPTION: Summary Statements Recommendations.

A prospective cohort study of early postpartum etonogestrel implant (Implanon®) use and its effect on duration of lochia

BACKGROUND

Etonogestrel (ENG) implants (Implanon(®)/Nexplanon(®)/Implanon NXT(®)) are employed as contraception in early postpartum patients. Follow-up is often not conducted by the hospital prescriber. Little is known about duration of lochia, in a modern setting, and even less is known about the effect of ENG implants on lochia.

AIMS

To determine if early postpartum (pre-discharge) insertion of Implanon for contraception was associated with a significant difference in duration of lochia. To record the number of patients who went on to have their Implanon removed during the study period and the reasons for removal.

METHODS

Prospective cohort study of 152 postpartum patients from a tertiary maternity unit in Hobart, Tasmania, Australia. The treatment group was women requesting Implanon prior to discharge. Controls were recruited from the same unit over the same time period, with the aim to match for birth weight and parity. Information was collected during face-to-face interviews or via telephone contact. Multivariate survival analysis was used to investigate lochia duration.

RESULTS

There were 73 controls and 79 women who had early postpartum Implanon inserted. Fourteen (17.7%) patients in the treatment group had their Implanon removed during the postpartum study period. In all of these cases the reason for removal was bleeding disturbance - prolonged or intermittent vaginal bleeding beyond 50 days postpartum. There was no significant difference in duration of lochia between the groups [median predicted duration 25 days (95% CI 22-27) in controls and 24 days (95% CI 21-26) in the treatment group].

CONCLUSIONS

Early postpartum insertion of Implanon for contraception was not associated with a statistically or clinically significant difference in duration of lochia.

Post Abortion Contraception

A safe induced abortion has no impact on future fertility. Ovulation may resume as early as 8 days after the abortion. There is no difference in return to fertility after medical or surgical abortion. Most women resume sexual activity soon after an abortion. Contraceptive counseling and provision should therefore be an integrated part of the abortion services to help women avoid another unintended pregnancy and risk, in many cases an unsafe, abortion. Long-acting reversible contraceptive methods that includes implants and intrauterine contraception have been shown to be the most effective contraceptive methods to help women prevent unintended pregnancy following an abortion. However, starting any method is better than starting no method at all. This Special Report will give a short guide to available methods and when they can be started after an induced abortion.

Cost-Effectiveness of Immediate Compared With Delayed Postpartum Etonogestrel Implant Insertion

OBJECTIVE

To evaluate the cost-effectiveness of immediate compared with delayed (6 weeks) postpartum etonogestrel implant insertion in preventing future unintended pregnancy.

METHODS

We constructed a decision-analytic model to examine a hypothetical population of women who request a contraceptive implant after giving birth. The timeframe for analysis was from the time of childbirth to 1 year postpartum. Model inputs were derived from a comprehensive literature review. We compared immediate (before discharge from the childbirth hospital stay) compared with delayed (at first postpartum office visit) postpartum placement of the contraceptive implant from a health care system's perspective. Implant insertion and removal, loss to follow-up at the postpartum visit, use of alternative contraceptive methods, and contraceptive failure were incorporated into the model. We calculated the incremental cost of immediate insertion for each pregnancy prevented during the first postpartum year and cost savings associated with pregnancies prevented. One-way sensitivity analyses were also performed. Cost estimates are reported in 2014 U.S. dollars.

RESULTS

Immediate postpartum implant insertion is associated with higher expected cost than delayed insertion ($1,091/patient compared with $650/patient) but is more effective in preventing pregnancies (expected pregnancy rate: 2.4% and 21.6%, respectively). This results in an incremental cost-effectiveness ratio of $2,304 per pregnancy prevented. When taking into consideration medical costs of the resulting unintended pregnancies that could be avoided, immediate implant insertion is expected to save $1,263 per patient.

CONCLUSION

Immediate postpartum provision of the contraceptive implant is cost-effective in preventing unintended pregnancies and should be provided to women requesting this form of contraception.

Characterization of Medicaid policy for immediate postpartum contraception

OBJECTIVE

Long-acting reversible contraception (LARC) is safe, effective and cost-saving when provided immediately postpartum but currently underutilized due to nonreimbursement by Medicaid and other insurers. The objectives of this study were to (a) determine which state Medicaid agencies provide specific reimbursement for immediate postpartum LARC and (b) identify modifiable policy-level barriers and facilitators of immediate postpartum LARC access.

STUDY DESIGN

We conducted semistructured telephone interviews with representatives of 40 Medicaid agencies to characterize payment methodology for immediate postpartum LARC. We coded transcripts using grounded theory and content analysis principles.

RESULTS

Three categories of immediate postpartum LARC payment methodology emerged: state Medicaid agency (a) provides separate or increased bundled payment (n=15), (b) is considering providing enhanced payment (n=9) or (c) is not considering enhanced payment (n=16). Two major themes emerged related to Medicaid decision-making about immediate postpartum LARC coverage: (a) Health effects: States with payment for immediate postpartum LARC frequently cited improved maternal/child health outcomes as motivating their reimbursements. Conversely, states without payment expressed misinformation about LARC's clinical effects and lack of advocacy from local providers about clinical need for this service. (b) Financial implications: States providing payment emphasized overall cost savings. Conversely, states without reimbursement expressed concern about immediate budget constraints and potential adverse impact on existing global payment methodology for inpatient care.

CONCLUSIONS

Many states have recently provided Medicaid coverage of immediate postpartum LARC, and several other states are considering such coverage. Addressing misinformation about clinical effects and concerns about cost-effectiveness of immediate postpartum LARC may promote adoption of immediate postpartum LARC reimbursement in Medicaid agencies currently without it.

IMPLICATIONS

Medicaid policy for reimbursement of immediate postpartum LARC is evolving rapidly across the US. Our findings suggest several concrete strategies to remove policy-level barriers and promote facilitators of immediate postpartum LARC.

Lactation and contraception

PURPOSE OF REVIEW

This review examines evidence relevant to the effect of hormonal contraception on breastfeeding; and compares global and US recommendations for contraceptive initiation and use. Breastfeeding and use of postpartum contraception have high public health priority, making research in this area critical for optimizing guidance.

RECENT FINDINGS

High quality evidence remains limited with only a small number of well-conducted randomized controlled trials of hormonal methods and breastfeeding/neonatal growth outcomes. More evidence supports early initiation of progestin-only methods. Evidence on early initiation of combination hormonal methods is sparse.

SUMMARY

The WHO Medical Eligibility Criteria (MEC) differs from that of the US MEC. Generally, the WHO MEC is more restrictive, reflecting the potential greater impact on maternal child health if there is a negative impact from hormonal contraception on breastfeeding. Only well conducted clinical trials will further elucidate such an impact.

Urgent need to change clinical practices about postpartum contraception

In the United States, maternal mortality and unintended pregnancy rates are increasing. There are growing disparities in maternal health between indigent, minority women and Caucasian women of higher socioeconomic status. Family planning has long been viewed as a solution to these problems. As reliance on permanent contraception has diminished, timely access to highly effective contraceptive methods, namely long acting reversible contraceptives, which includes the contraceptive hormonal implant and intrauterine device - has become even more important. For women in the United States and abroad, the time of delivery is the one reliable opportunity for women to receive medical care. Consistently, research has shown that providing contraception in the immediate postpartum period is safe, effective, feasible and cost effective. However, misperceptions, lack of supplies, and reimbursement issues combine to defeat attempts to provide the most effective methods of contraception during that hospitalization. We believe that it is time to tackle the problem of unintended and rapid repeat pregnancy using an evidence-based, patient-centered paradigm and to eradicate systemic barriers blocking access to contraceptive methods during hospital stay. This editorial will outline some of the more compelling evidence supporting this move and will provide insights from successful programs.

Immediate postpartum initiation of etonogestrel-releasing implant: A randomized controlled trial on breastfeeding impact

BACKGROUND

Breast milk volume has never been evaluated when the etonogestrel (ENG) implant was inserted immediately postpartum. Thus, this study evaluated if the immediate postpartum insertion of the ENG implant alters breast milk volume.

STUDY DESIGN

Twenty-four postpartum women and their newborns (NBs) were randomized into two groups: Implant group (ENG implant inserted within 48 h after delivery) and Control group (absence of contraceptive method). The primary outcome was the amount of breast milk intake by the NBs in the first 6 weeks after delivery. Five and ten grams of deuterium (D(2)O) were orally administered to the postpartum women on the day of randomization (day 0) and on the 29th study day, respectively. Saliva samples were collected from the mother-NB pairs prior to each D(2)O dose administration and after D(2)O ingestion (periodic collection). The amount of breast milk ingested by the NBs was estimated by the amount of deuterium (D(2)O) ingested by the NBs through breastfeeding, using mass spectrometry in the saliva samples.

RESULTS

Twenty-four postpartum women and their NB were randomized (12 per group). The median of breast milk intake by NBs following the two D(2)O doses were similar between groups {first D(2)O dose [Implant: 340 mL/day (240-420 mL/day) vs.

CONTROL

330 mL/day (300-530 mL/day), p=.54]; second D(2)O dose [Implant: 845 mL/day (770-980 mL/day) vs.

CONTROL

785 mL/day (680-980 mL/day), p=.63]}. The exclusive breastfeeding rate and NB weight were similar between groups in the first 6 weeks postpartum.

CONCLUSION

ENG implant insertion immediately postpartum does not alter the volume of breast milk intake by NBs.

IMPLICATIONS

Considering the benefits of immediate postpartum initiation of ENG implant on reducing unintended pregnancy and pregnancy recurrence, especially in vulnerable populations, our study adds safety data on breastfeeding effect of this practice.
