Q
What are 5 main reasons for starting contraception?

- Avoid pregnancy
- Period control e.g. haemorrhagia
- Acne control
- Management of polycystic ovaries

2
Q
What are 9 areas of the gynaecological history that should be explored when starting contraception?
A
- Why they’re starting contraception and what they hope to get out of it
- Menstrual cycle: is it regular/prolonged, ⇒ some can help improve but can make it worse
- Irregular bleeding e.g. post-coital menstrual bleeding; can be a sign of STIs, if put coil in can cause pelvic inflammatory disease. Could also symbolise gyaencological cancer which could be worsened by some contraceptives
- Age: young (<16y), is she competent? As she gets older will increase risk of other medical problems, particularly with oestrogen containing contraceptives
- Any contraception already used, what they like/ don’t like
- Past pregnancies, particularly ectopic as some progesterone only can increase risk of ectopics
- Past pregnancies can also make putting coil in a bit easier (but not essential)
- What thinking about for future - want to get pregnant soon or never at all? Help decision
- Unprotected sex recently - STI risk
3

11
Q
What are 4 things to think about that might make it easier to take a focused history to make sure the patient doesn’t have contraindications to any contraceptives without asking every problem?
A
- Whether patient already knows which contraceptive she does or doesn’t want, to reduce number of CIs to rule out
- Medical problems you must ask about regardless of contraceptive
- Medical problems that are only imporant for specific contraceptives
- Could give pre-reading in a leaflet or online such as Family Planning Association link, ask to come back if she is happy to do this

15
Q

141
How does the vaginal ring work and how is it inserted?
* Ring releases a constant dose of hormones into the bloodstream through the vaginal wall. It inhibits ovulation and also thickens cervical mucus and thins the uterine lining so it's harder for implantation to occur
* Doctor or nurse advises patient on how to insert/remove; squeeze between thumb and finger and use one hand to insert into vagina, push it in until it feels comfortable
142
