IUD usage has decreased steadily since 1998 whereas Mirena and especially Implanon/Nexplanon usage have increased substantially over the same period Usage of Depo Provera remained stable * In thousand cycles sold

13 CHOICE Study 9,256 women aged recruited from St. Louis region, US All participants received reversible contraceptive method of their choice at no cost Abortion rates in CHOICE cohort less than half regional and national rates (P<0.001) Fell by 21% during study Teenage birth within CHOICE cohort 6.3 per 1,000 compared with 34.3 per 1,000 US rate Expanding study nationally could save 41-71% of abortions in US Peipert et al. Obstet Gynecol 2012; Oct 3 (eprint)

14 Are women satisfied with their method? Women using LARC methods had the highest satisfaction at 1 year follow up Peipert JF et al. Obstet Gynecol 2011; 117(5):

15 Contraceptive awareness needs to be improved YouGov 2010 survey of 503 women aged 16 to 24 77% wanted a contraceptive method that they didn t have to think about every day plan for during sex Only 1% were aware of all 4 LARCs (IUD, IUS, contraceptive implant, and injection) Just 7% were using an IUD, IUS, contraceptive implant, or injection awareness_of_reliable_contraception_increases_the_risk_of_unplanned_pregnancies.aspx

16 Providing contraceptive choice demonstrates that the majority of women will choose LARCs Contraceptive method choices after counselling (N=2,500) 1 Long-acting Shorter-acting 33% 67% LARC=long-acting reversible contraceptive. 1. Secura GM et al. Am J Obstet Gynecol. 2010;203:115.e1 115.e7 2. Mestad et al. Contraception 2011;84: % of year-olds chose a LARC with 63% of these choosing an implant 2

21 Nexplanon Audit Leeds Student Medical Practice A prospective study of 400 women who had an etonogestrel contraceptive implant (Nexplanon ) was initiated in September 2010 A questionnaire was completed at fitting with telephone follow up arranged at 3, 6 and 12 months

22 Reasons for requesting an implant were:- 54% active choice 34% current contraceptive problems 9% implant due for replacement 3% medical contraindications to other methods

23 Contraceptive use prior to implant fitting was:- 46% COC 16% POP 13% condoms 11% subdermal implant 4% no regular method

24 At 6 months -197 patients: 95% still had the implant 5% implant removed Of the women who still had the device 16% were using medication to control side effects: 72% COC 4% contraceptive patch 8% progestogen 8% acne treatments 4% mefenamic acid 4% paracetamol Main reason for removal: Unacceptable bleeding (n=8) mood swings (n=1)

25 Continuation rates 86.2% 54.7% DMPA=depomedroxyprogesterone acetate; OCP=oral contraceptive pill. Peipert JF, et al. Obstet Gynecol. 2011;117: ~4-fold higher discontinuation rate with non-larc

26 LARC does prevent further unplanned pregnancies post-abortion Case-note review, Scotland Over two year period 12.3% repeat abortion Teenagers 10 times more likely to have repeat abortion Social deprivation had no effect Using COC as a reference (age controlled) IUS/IUD and implant associated with lowest chance of repeat abortion IUS/IUD users 20 times less likely Implant users 16 times less likely Injectable users similar to COC/no method users Cameron et al. BJOG 2012:119;

27 Intrauterine contraception and nulliparous women Use patient choice complex medical problems e.g. cardiovascular disease, HIV, taking liver enzyme inducers Safety in nullips no evidence of increased risk of expulsion, pelvic infection or infertility well-accepted (80% for IUS versus 73% in COC group at 12 months) easily fitted Pakarinen, Contraception, 2003; Prager et al. Contraception 2007

28 For many women, a daily contraceptive regimen may not be a suitable option Up to 32% of women on a new oral contraceptive discontinue use within 6 months 1 The Pill is user dependent and requires regular visits to HCPs NICE states that: Increased use of Long-Acting Reversible Contraception (LARC) methods will reduce the number of unintended pregnancies 2 1. Rosenburg MJ and Waugh MS, Am J Obstet Gynecol. 1998; 179: NICE. Clinical Guideline No. 30, Long-acting Reversible Contraception; October 2005

32 NICE & LARC Women should be provided with sufficient information to make an informed choice Health Care Professionals (HCPs) who do not provide LARC should have a referral mechanism in place HCPs should receive training to develop and maintain skills to provide LARC NICE. Clinical Guideline No. 30, Long-acting Reversible Contraception; October 2005

33 NICE & LARC LARC methods are cost effective options* LARC methods are more cost-effective than the combined oral contraceptive even at 1 year of use IUD, IUS & implants are more cost-effective than injections NICE. Clinical Guideline No. 30, Long-acting Reversible Contraception; October 2005 * Cost effectiveness relates to the comparative analysis of alternative courses of action in terms of their costs and consequences e.g. Cost: ingredient cost, visits, disposables, removal and method failure. Consequence: unintended pregnancy avoided.
