Acceptability and satisfaction using Quick Start with the contraceptive vaginal ring versus an oral contraceptive.

BACKGROUND: Many women discontinue their use of hormonal contraception, and even those who continue so may have difficulty using oral contraceptive pills consistently. New delivery systems, including the vaginal ring, may be easier to use, but user acceptability and satisfaction with these new methods may be affected by women's experience with their bodies. MATERIALS AND METHODS: Data for this study were collected as part of a randomized clinical trial on 201 women comparing immediate start of vaginal ring use with immediate start of low-dose oral contraceptive use. We assessed user satisfaction and method continuation 3 months after ring or pill initiation. RESULTS: At 3 months, 174 of 201 subjects (87%) had follow-up interviews. Among the 174 study participants with follow-up data, 61% of ring subjects and 34% of pill subjects were very satisfied with their methods (p=.003). For posttrial contraception, 79% of ring subjects chose to continue with the ring whereas 59% of pill subjects chose to continue with the pill (p<.001). Women who reported greater comfort in touching their genitals, greater frequency of masturbation, more comfort with intercourse and past use of vaginal contraceptives and products were not more likely than others to be satisfied with the ring or to continue using it for birth control. CONCLUSION: Women who were allocated to vaginal ring use, regardless of their baseline characteristics or behavior, were likely to be highly satisfied with the method and to continue its use.

Bleeding patterns after immediate initiation of an oral compared with a vaginal hormonal contraceptive.

OBJECTIVE: This study compared 84-day bleeding patterns after immediate initiation of a triphasic oral contraceptive with a 25-mug daily dose of ethinyl estradiol (E2) compared with the contraceptive vaginal ring, which has a 15-mug daily dose of ethinyl E2. METHODS: This was an open-label controlled trial. We randomly assigned 201 women to immediate start of a contraceptive pill or immediate start of the ring in a 1:1 allocation ratio. Our primary outcome was difference in mean bleeding-spotting days per woman according to treatment assignment. Secondary outcomes were differences in World Health Organization-defined menstrual indices, differences in perceived bleeding changes, and differences in bleeding according to cycle day at the start of method. RESULTS: The mean bleeding-spotting days in the 84-day reference period for all subjects was 19.2 days (17.0 days for ring users and 21.4 days for pill users, mean difference 4.4 days). Using the World Health Organization menstrual indices, the ring users experienced fewer days or episodes of bleeding-spotting and shorter intervals. Among ring users, no baseline characteristics were associated with bleeding outcomes. Older nulliparous pill users, however, reported more bleeding-spotting days. Significantly more ring users reported a decrease in duration of bleeding compared with pill users (P < .01). We found no significant differences in bleeding patterns based on analysis of cycle day at study enrollment. CONCLUSION: Our study shows advantageous bleeding patterns for subjects using the contraceptive vaginal ring. It also confirms our previous findings that immediate start of hormonal contraception is an acceptable alternative to waiting for menses. LEVEL OF EVIDENCE: II-1.
