College WomenA new era of contraception

Beth Kutler FNPGannett Health ServicesCornell UniversityBK82@Cornell.edu

The purpose of this activity is to enable the learner to counsel effectively about long acting contraceptive methods (Intrauterine devices and implantable rods) as well as learn new insights for effective placement and management of potential side effects

2013 ACHA National College Health Assessment :

o 49.2% of females had vaginal sex in the 30 days prior to the survey

o 1.9 % of college students who had vaginal intercourse within the last 12 months reported experiencing an unintentional pregnancy in that time frame

o 18.8 % reported using EC within the last 12 months

Intrauterine Contraception in Nulliparous Women a Prospective Observational Study

Study Objectives:

Assess nulliparous women’s satisfaction with the IUD as a method of contraception Identify any medical history that may predict satisfaction or dissatisfaction with this

method Quantify the rates of discontinuation and/or complications for IUD use among nulliparous

women

117 women currently enrolled in ongoing study. Receive surveys at 1 ,6, 12 and 18 months following placement

How likely are you, at this point (6mo) are you to recommend the IUD to a friend ?

But what about…?

• Multiple sexual partners• Nulliparity• Future fertility• Placement trouble

IUDs Do Not Cause Infertility

• Infertility is not more likely after IUD discontinuation compared to other reversible methods

• No evidence that IUD use is associated with subsequent infertility

• Chlamydia, not previous IUD use, is associated with infertility

Safety: IUD Does Not Cause Infertility

• IUD is not related to infertility• Chlamydia is related to infertility

Ectopic Pregnancy

• IUDs may be offered to women with a history of ectopic pregnancy (MEC cat. 1)

• IUD use does not appear to increase absolute risk

o Ectopic rate with IUD= 0.5/1,000 women-years

o Ectopic rate with no contraception= 3.25-5.25/1,000 women- years

o However, if pregnancy does occur with an IUD in place, the pregnancy is more likely to be ectopic

Sivin I. Dose- and age-dependent ectopic pregnancy risks with intrauterine contraception. Obstet Gynecol 1991;78:291–8.

Ectopic Pregnancy

Copper IUD 0.34*

*Ectopic pregnancies per 1,000 woman-years

Safety: IUDs Do Not Cause PID

• PID incidence for IUD users is similar to that of the general population

• Risk is increased only during the first month after insertion

• Preexisting STI at time of insertion, not the IUD itself, increases risk

Screening: Poor Candidates for Intrauterine Contraception

• Known or suspected pregnancy• Puerperal sepsis• Immediate post septic abortion• Unexplained vaginal bleeding• Cervical or endometrial cancer• Uterine fibroids that interfere with

placement• Current purulent cervicitis, chlamydia,

or gonorrhea

WHO. Medical Eligibility Criteria for Contraceptive Use.

Copper IUD • ParaGard polyethylene wrapped with

copper wire

• Approved for use up to 10 years (probably more)

• Mechanisms of action: Inhibition of sperm migration and

viability Change in ovum transport speed Damage to or destruction of ovum Damage to or destruction of

fertilized ovum All effects occur before

implantation

• Highly effective

LNG IUS

• Mirena LNG IUS releases 20 mcg levonorgestrel/day

• Approved for use up to 5 years (probably more)

• Mechanisms of action: Similar effects as copper IUD Also causes endometrial suppression

and changes in cervical mucus All effects occur before implantation

• Highly effective

New LNG IUS

• Skyla LNG IUS releases 14 mcg levonorgestrel/day

• Approved for use up to 3 years

• Highly effective

IUD Placement

Suffrin et al OB. Gyn 2012 120: 1314-21

57,728 IUD insertions:

• 47% unscreened• 19% screened on day IUD was inserted

• Overall PID risk within 90 days= 0.54%• No difference in PID regardless of screening

Screen at risk women through most convenient process

Screening for STI chlamydia and gonorrhea

• Pre placement counseling essential• 800 mg Ibuprofen 1 hour prior to placement

±• Anxiolytics• 50 mg Tramadol• Topical and/or instilled lidocaine• Cervical blocks• Misoprostol• Menses

Post-Abortion Insertion

• Insertion of an IUD immediately after abortion or miscarriage is safe and effective

– Significantly reduces the risk of repeat abortion

– Increases rates of use

– Adolescents should be counseled regarding risk of expulsion

Copper IUD as EC

• Most effective method of emergency contraception

• Can be inserted up to 5 days after unprotected intercourse to prevent pregnancy

Side effects from the copper IUD: do they decrease over time? David Hubacher , ⁎Pai-Lien Chen, Sola Park. Contraception 79 (2009) 356–362

Copper T related bleeding can decrease over time

Managing Bleeding Concerns

• Anticipatory guidance and reassurance• Treat with NSAIDs• Cycle with oral contraceptives

• 70% experience oligomenorrhea or amenorrhea within 2 years of insertion of Mirena

• These numbers likely to be lower with Skyla

3 most common reasons for requesting removal before 6 months of use

ConvenientLong acting reversible method. Discrete. Effective for 3 years

Effective0.5 to 1 pregnancy /1,000 users

ReversibleAfter implant is removed, most women (94%) ovulate by 3 months; the

majority ovulate within 3 weeks. Drug level is undetectable one week after removal. Funk S, Contraception. 2005 May;71(5):319-26.

SafeProgesterone only. MEC 1 or 2 where estrogen is contraindicated. Inhibits ovulation

No evidence of long-term effects such as deep vein thrombosis or anemia. Studies regarding bone mineral density have been conflicting. BeerthuizenR, Hum Reprod. 2000;15:118-122.

Nexplanon

Easy Placement

• Insertion in <1 min• Removal 3-5 min• 1% complications related to insertion• 1.7% related to removal

• Can be placed anytime pregnancy reasonably excluded• Back up method for 7 days unless :

• inserted within 5 days of menses• immediately post-abortion• Immediately upon switching from another hormonal method

Managing Bleeding Concerns

• Common strategies include short courses of combined OCs or NSAIDs – No published placebo controlled trials to support use of

these treatments

• Limited data suggest decreases in bleeding episode length with:– Mefenamic acid – Mifepristone in combination with ethinyl estradiol or

doxycycline – Doxycycline alone
