Background:
With advance notice about the availability and effectiveness of contraceptive methods, abortion patients have more time and information for decision-making. We assessed the impact of an informational telephone call prior to the surgical abortion visit on patient contraceptive knowledge.
Methods:
This was a pilot randomised controlled trial. Prior to their abortion visit, participants were randomised to the intervention message, a standardised notification about the availability, effectiveness and safety of long-acting (LARC) and short-acting reversible contraception (SARC) on the day of the abortion, or to the control message, a reiteration of appointment logistics without information about contraception. At the visit, participants completed a pre-procedure survey to assess contraceptive knowledge and usefulness of the intervention. The primary outcome was knowledge of LARC availability immediately after surgical abortion. A secondary outcome was contraceptive method uptake.
Results:
We enrolled 234 subjects. The pre-visit telephone notification improved knowledge that LARC is available immediately after surgical abortion (71.3% vs 50.9%, P<0.01). Participants in both study arms found the telephone notifications useful. Post-abortion contraceptive method choice did not differ between study arms.
Conclusions:
Advance notice about contraception was acceptable to surgical abortion patients and improved their contraceptive knowledge.
Trial Registration Number:
NCT02836561.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
