Study summary

A barrier to initiating progestin contraceptives in the early postpartum period is the concern of interference with breastfeeding, specifically lactogenesis. In this trial, the investigators aim to describe the effects of immediate insertion of the contraceptive implant on breastfeeding. The investigators seek to examine the time to lactogenesis with immediate post-delivery insertion in delivery room versus insertion of a contraceptive implant in the postpartum ward prior to medical discharge. For this study, 82 consenting women will be randomized to immediate implant insertion (0-2 hours following delivery) in the delivery room or insertion of the implant following delivery in postpartum room and prior to medical discharge (24-48 hours following delivery).

Participants complete a questionnaire that asks questions about breastfeeding continuation, supplementation, duration, and exclusivity. This questionnaire also includes questions about contraceptive continuation, patient satisfaction with implant, pregnancy, and postpartum care visits.

What researchers measure

Primary outcomes

  1. Time to Lactogenesis Stage II [Questionnaire]

    Lactogenesis Stage II: The initiation of copious milk secretion as documented by maternal perception. To obtain measurement of time to lactogenesis, we will document time at which participants perceive initiation of copious milk secretion using a set of specific validated questions and subtract this by the documented time of delivery.

    Time frame: Participants will be monitored daily by the research staff, in the first seven days postpartum, or until lactogenesis reported, beginning at 24-hours following delivery, to determine time to lactogenesis stage II.

Secondary outcomes

  1. Number of of Participants Actively Breastfeeding

    Exclusive breastfeeding means feedling with breast milk only. Any breast feeding means feeding with breast milk, with water and/or formula.

    Time frame: 2 weeks, 4 weeks, 3 months, 6 months, and 12 months after delivery

  2. Number of Participants Still With the Contraceptive Implant at Month 12.

    Time frame: month 12

  3. Number of Participants Satisfied or Very Satisfied With Implant Contraceptive

    Participant-rated as very satisfied, satisfied, neither satisfied or dissatisfied, dissatisfied, or very dissatisfied.

    Time frame: month 12

  4. Number of Participants Reporting a Pregnancy Within 12 Months

    Time frame: 12 months

  5. Number of Participants Attending a Postpartum Care Visit by Month 3

    Time frame: month 3
