Plain English Summary
Background and study aims:
An abortion is the deliberate termination of a pregnancy, most often performed during the first 28 weeks of pregnancy. In May 2010, the Department of Health released the latest abortion statistics. Total number of abortions in England and Wales were 189,100 in 2009, compared with 195,296 in 2008, a fall of 3.2%. Abortion rate was highest in women aged 19-21, whilst rates under-16 and under-18 were lower. 91% of abortions were carried out in women up to 13 weeks pregnant and 75% up to 10 weeks. Medical abortions accounted for 40% of the total. It is clear from this data that abortion treatments continue to be provided on a large scale. Newer methods are continuing to be developed to provide women with safe and effective methods. Interestingly not all methods are acceptable to all women and therefore the question of patients’ preferences and acceptance poses a clinical dilemma. The few studies that explored shorter time intervals show conflicting evidence have resulted in a large variation in clinical practice for administration of medications at different time intervals for medical abortions. The aim of this study is to assess the acceptability and success of shorter time interval treatments compared to standard time intervals treatments as well as exploring women’s perceptions and views through interviews.
Who can participate?
Adult women who are requesting an abortion
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive the standard treatment regimen, involving misoprostol (a medication used to start labour) being given vaginally 24 hours after being given mifepristone (a medication used to bring about abortion). Those in the second group receive the same treatment but with a 6-8 hour window instead of 24 hours. Participants in both groups are followed up for two weeks to find out how acceptable the treatment they receive is.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating.

A randomised controlled trial on Efficacy of mifepristone followed by 6-8 hours versus 24 hours vaginal misoprostol in Early Medical Abortions (< 63 days gestation)
TIMES Study (Time Interval for Medical Early abortionS)
The hypothesis for this study is to determine the efficacy of shorter time intervals of administration of misoprostol and also to assess the reliability of follow-up methods to confirm completeness of medical abortion. To explore womens beliefs and preferences to different medical methods within the framework of the randomised controlled trial.

Early medical abortion
Participants are randomised to one of two groups using computerised randomisation
Control group: Participants receive the standard treatment regimen of 800mcg of misoprostol as vaginal route 24 hours following administration of 200mg of mifepristone
Intervention group: Participants receive 800 ug of misoprostol given vaginally after 200 mg of mifepristone at 6-8 hours interval or 24 hours interval.
All women will be followed up to a period of 2 weeks.
Primary outcome measures
Proportion of complete abortions where no further medical or surgical intervention beyond the initial dose of vaginal misoprostol required was measured using patient acceptability questionnaire and ultrasound confirmation at the end of 2 weeks.
Secondary outcome measures
1. Induction to abortion interval is measured using based on the duration of pain and bleeding at 2 weeks follow up
2. Adverse effects is measured using Likert scale at 2 weeks follow up
3. Pain is measured using VAS at 2 weeks follow up
4. Duration of Bleeding is measured using the No.of hours or days at 2 weeks follow up
5. Acceptability of women towards the new regimen is measured using Likert scale at the 2 weeks follow up
6. Assess reliability of follow-up methods following medical abortion is measured using telephone follow up at 1 week and Urinary quantification of hCG at baseline.2 weeks
For the purpose of qualitative study face to face in depth interviews were conducted at the end of 2 weeks
