Contraceptive method preference and reasons for contraceptive discontinuation among women randomized to intramuscular depot medroxyprogesterone acetate, a copper intrauterine device or a levonorgestrel implant: Findings from Durban, South Africa.

OBJECTIVES

The use of intrauterine devices (IUDs) and contraceptive implants in South Africa is low with limited data on patterns of use and reasons for discontinuation. We describe contraceptive preferences and reasons for discontinuation among women enrolled in the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial from one trial site.

STUDY DESIGN

ECHO, conducted between 2015 and 2018, enrolled and randomized sexually active women, aged 16 to 35, and desiring contraception, to intramuscular depot medroxyprogesterone acetate (DMPA-IM), a copper intrauterine device (copper-IUD) or a levonorgestrel (LNG) implant; follow-up was 12 to 18 months. We interviewed 829 women at the Durban, South Africa trial site at ECHO Trial exit to ascertain contraceptive preferences at randomization. Reasons for randomized contraceptive discontinuation were collected at ECHO Trial exit and 6 months later. Data were analyzed descriptively.

RESULTS

At the final ECHO Trial visit, among women using their randomized contraceptive method (n = 757), 21% discontinued DMPA-IM, 20% discontinued LNG implant and 22% discontinued the copper-IUD. About a quarter from each group discontinued due to problems with bleeding. Among women continuing their randomized contraceptive at trial exit (n = 597), 25% discontinued DMPA-IM within 6 months of exiting the study, 8% discontinued LNG implant and 4% discontinued copper-IUD. A third of women reported wanting to be assigned DMPA-IM at randomization, 20% wanted the LNG implant and 18% the copper-IUD.

CONCLUSIONS

Despite some women having preferences about which contraceptive they might be randomized to, discontinuation rates for all three methods at ECHO Trial exit and 6-month post-trial follow-up were low.

IMPLICATIONS

Despite limited prior use of IUDs and implants among women enrolled in this study, and a desire by some women to not receive these methods at randomization, discontinuation rates remained low. The provision of quality contraceptive counselling and support may increase uptake and continued use of implants and IUDs.
