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

ABSTRACT: 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.

Project description:BackgroundImmediate 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.ObjectiveThis study examined the effect of immediate vs delayed postpartum levonorgestrel intrauterine device insertion on breast-feeding outcomes.Study designWe 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.ResultsWe 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.ConclusionOur 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.

Project description:ImportanceFacilitating access to the full range of contraceptive options is a health policy goal; however, inpatient provision of postpartum long-acting reversible contraceptive (LARC) methods has been limited due to lack of hospital reimbursement. Between March 2014 and January 2015, the Medicaid programs in 5 states began to reimburse hospitals for immediate postpartum LARC separately from the global maternity payment.ObjectiveTo examine the association between Medicaid policies and provision of immediate postpartum LARC, and to examine hospital characteristics associated with policy adoption.Design, setting, and participantsThis cross-sectional study used interrupted time series analysis. The setting was population-based in Georgia, Iowa, Maryland, New York, and Rhode Island. Participants included individuals who gave birth in these states between 2011 and 2017 (n = 3 097 188). Statistical analysis was performed from June 2021 to August 2022.ExposuresChildbirth after the start of Medicaid's reimbursement policy.Main outcomes and measuresImmediate postpartum LARC (outcome), teaching hospital, Catholic-owned or operated, obstetrical care level, and urban or rural location (hospital characteristics).ResultsThe study included a total of 1 521 491 births paid for by Medicaid and 1 575 697 paid for by a commercial payer between 2011 and 2017. Prior to Medicaid reimbursement changes, 489 389 of 726 805 births (67%) were to individuals between 18 and 29 years of age, 219 363 of 715 905 births (31%) were to non-Hispanic Black individuals, 227 639 of 715 905 births (32%) were to non-Hispanic White individuals, 155 298 of 715 905 births (22%) were to Hispanic individuals, and 113 605 of 715 905 births (16%) were to individuals from other non-Hispanic racial groups. Among Medicaid-paid births, the policies were associated with an increase in the rate of immediate postpartum LARC provision in all states, although results for Maryland were not consistent across sensitivity analyses. The change in trend ranged from a quarterly increase of 0.05 percentage points in Maryland (95% CI, 0.01-0.08 percentage points) and 0.05 percentage points in Iowa (95% CI, 0.00-0.11 percentage points) to 0.82 percentage points (95% CI, 0.73-0.91 percentage points) in Rhode Island. The policy was also associated with an increase in immediate postpartum LARC provision among commercially paid births in 4 of 5 states. After the policy, only 38 of 366 hospitals (10%) provided more than 1% of birthing people with immediate postpartum LARC. These adopting hospitals were less likely to be Catholic (0% [0 of 31] vs 17% [41 of 245]), less likely to be rural (10% [3 of 31] vs 33% [81 of 247]), more likely to have the highest level of obstetric care (71% [22 of 31] vs 29% [65 of 223]) and be teaching hospitals (87% [27 of 31] vs 43% [106 of 246]) compared with nonadopting hospitals.Conclusions and relevanceThis cross-sectional study's findings suggest that Medicaid policies that reimburse immediate postpartum LARC may increase access to this service; however, policy implementation has been uneven, resulting in unequal access.

Project description:ObjectiveThis study aimed to assess the intention and barriers to the use of immediate postpartum intrauterine contraceptive devices among pregnant women attending antenatal clinics in Jimma town public healthcare facilities, southwest Ethiopia.MethodsA facility-based cross-sectional study design was conducted from 1 September to 30 October 2020 by using a systematic sampling technique. Data were entered into Epi-data 3.1 version and exported to Statistical Package for Social Sciences 23 for analysis. A binary logistic regression analysis was done to sort candidate variables for multiple logistic regression, and multivariable logistic regressions were done to identify factors associated with the intention to postpartum intrauterine contraceptive devices. Factors associated with intention to use immediate postpartum intrauterine contraceptive device declared at 95% confidence interval.ResultsThis study finding showed that 37.6% (95% confidence interval (31.5, 43.7)) of pregnant women intended to use the immediate postpartum intrauterine contraceptive device after their delivery. The main reason women refused to use immediate postpartum intrauterine contraceptive devices was being satisfied with other methods to use after they gave birth (27.5 %), the concern of health harm (22.2%), and the fear of impaired future fertility (16.4%). The identified factors that were statically significant with the intention to use immediate postpartum intrauterine contraceptive devices among pregnant women were included: attended secondary education (adjusted odd ratio = 2.36; p = 0.03; 95% confidence interval (1.089, 5.128)), attended college and above (adjusted odd ratio = 2.99; p = 0.020; 95% confidence interval (1.189, 7.541)), have high knowledge on immediate postpartum intrauterine contraceptive devices ((adjusted odd ratio = 2.10; p = 0.006; 95% confidence interval (1.236, 3.564)), the previous history of LACM used (adjusted odd ratio = 6.85; p = 0.0001; 95% confidence interval (3.560, 10.021)), parity >4 (adjusted odd ratio = 1.86; p = 0.043; 95% confidence interval (3.99, 8.703)).ConclusionThe intention of pregnant women to use after they gave birth in the study area was low. Maternal educational level, high knowledge, history of previous long-acting contraceptive methods use, and parity were significantly associated with pregnant women's intention to use immediate postpartum intrauterine contraceptive devices. Healthcare providers should focus on delivering crucial information about immediate postpartum intrauterine contraceptive device benefits for postpartum women, particularly concerning reducing barriers during antenatal care follow-up as they plan to use it after their delivery.
