Outcomes
Primary outcome [1] 279741 0
The efficacy of mifepristone priming in achieving pregnancy interruption in mid-trimester fetal demise. This will be determined by assessing the median time to delivery in both groups with the primary aim being a 30% reduction in time to delivery in group 1.
Timepoint [1] 279741 0
At delivery point
Secondary outcome [1] 294349 0
Amount of blood loss. All patients at King Edward Memorial Hospital have their post partum blood loss weighed to accurately measure loss.
Timepoint [1] 294349 0
Peri-partum - 2 hours post placental delivery
Secondary outcome [2] 294350 0
% of cases with retained placenta
Timepoint [2] 294350 0
At one hour post devliery of the fetus
Secondary outcome [3] 294351 0
Side effects of mifepristone. Midwifery staff complete a patient observation form during and post delivery. This includes the amount of analgesia required and the presence or absence of pain, nausea, vomiting or diarrhoea.
Timepoint [3] 294351 0
4 hours post delivery
Secondary outcome [4] 294352 0
Maternal satisfaction is assessed using a patient question. A Likert scale with 0 being much worse than expected and 10 being much better than expected is used in relation to the following statements.

1. What did you think of the procedure
2. How would you rate your pain during the procedure
3. Would you recommend this method of termination to a friend in a similar situation
4. How much control did you feel you had

Patients are also given the opportunity for free form comment

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The investigators will allocate a unique study participant number to the patient. This will be sequential and documented in a data set booked and in the patient notes.

This will also be recorded on the national inpatient medication chart.

The medication chart will be sent to pharmacy. The pharmacist will therefore be informed of the patients allocated number.

Prior to the study starting, the pharmacist will use a random sampling program to allocate case and controls to the unique study identifiers. The pharmacist will provide the mifepristone or placebo as appropriate.

Therefore, the study investigators, the participants and the staff administering the treament will be blinded to the patients group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The patients will be allocated a study participant number. Prior to the commencement of recruiting, the pharmacists will use a random sampling program to assign each study participant number to treatment or placebo.
Masking / blinding
