Abstract

Background: The study was conducted to perform a direct comparison of the satisfaction of intrauterine device (IUD) users and Implanon users after 6 months.

Study design: Women were recruited to this study in the contraception clinics of Southern Health and Family Planning Victoria. Each woman completed a questionnaire at the time of starting her contraception with either an IUD or Implanon. Women were sent a follow-up questionnaire after 6 months to assess their satisfaction with their chosen method of contraception.

Results: A total of 439 participants were recruited for this non randomized cohort study; 211 choosing an IUD and 228 choosing to use Implanon. The main reason patients in both groups chose their contraceptive method was recommendation by the doctor. Follow-up was achieved in over 84% in both groups. More than 50% of women in both groups reported at least one side effect. The most commonly reported side effect in both groups was abnormal bleeding and this was also the most common reason for having the contraceptive device removed. The IUD users reported a higher rate of satisfaction with their chosen method of contraception, although there was no difference between groups in the removal rate or whether the women would recommend the contraception to others.

Conclusions: IUD users reported a higher level of satisfaction than did Implanon users at 6 months. Side effects in women using IUDs and Implanon are common. The range of likely side effects should be included in counseling women about long-term reversible contraception.
