Priority 3 from the Contraception PSP

UNCERTAINTY: What are the long-term effects of using contraception (pills, patches, rings, injections, implants, intrauterine) on fertility, cancer and miscarriage? (JLA PSP Priority 3)
Overall ranking 3
JLA question ID 0049/3
Explanatory note This mirrors a NICE LARC guideline research recommendations: “Most women will need to use contraception for more than 30 years… a woman's choice and acceptance of LARC may be influenced by potential health dis-benefits (side effects and risks) as well as non contraceptive benefits of LARC (such as alleviation of menorrhagia)” The short and long term effects of contraceptive choices were a frequently raised.  The RCGP oral contraceptive study provides an important update on the effect of contraceptives on cancer outcomes. It takes time to study these long term outcomes, this cohort of more than 40,000 women were recruited in 1968, they have been followed them for more than 40years. Evaluation of LARC methods and up to date oral regimens/topical regimes are needed.

Original uncertainty examples

“Is there long term side effects of using the oral contraceptive pill? Women can use this medication for many years, in some cases (maybe a lot of cases) from their teenage years until they get menapause. Is this bad for your health? Is there a cancer risk? “ (Patient) ~ “Coil/mirena/pill - Does it increase my  chance of getting cancer?” (Patient) ~ “I am often asked about the long term effects of the implant and ius.” (HCP) ~ “More clarity about long term effects on fertility in regard to all forms of hormonal contraception and the IUD. I have found particular concerns surrounding the IUS and IUD in this matter.” (both)
