Brief summary

To compare rates of etonogestrel implant discontinuation in implant initiators who are given advance provision of combined oral contraceptive pills (COCs) and a bleeding rescue regimen (COCR intervention) to participants given standard counseling (comparator).

Detailed description

Objective: To compare rates of etonogestrel implant discontinuation in implant initiators who are given advance provision of combined oral contraceptive pills (COCs) and a bleeding rescue regimen (COCR intervention) to participants given standard counseling (comparator). Secondary Objectives: To determine if participants initiating the contraceptive implant who are also provided COCR are more likely than participants receiving standard counseling to: 1. report higher levels of satisfaction with their contraceptive implant at one year following initiation 2. require less clinical follow-up and clinical resources in the year following initiation.

Interventions

DRUGEthinyl Estradiol / Norgestimate Oral Tablet

Those who desire COCs as an intervention are prescribed (over the phone) or given (in person) 3 packs of COCs. They are told to take one pill per day until the first pack is complete and save the remaining 2 packs for possible future use.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Implant Continuation12 months post-insertionWe will assess continuation of use of the contraceptive implant.

Secondary

MeasureTime frameDescription
Overall Satisfaction With Contraceptive ImplantAssessed at 3, 6, and 12 months post-insertion, 12 months reportedWe will assess satisfaction with the bleeding profile and overall satisfaction using a Likert scale ("very satisfied", "somewhat satisfied" and "not satisfied"). Overall satisfaction at 12 months will be used as a measure for data analysis.
