About this trial
This study will investigate the use of a point of care test in patients who are having an abortion at a gestation of \<6 weeks (known as a very early medical abortion). These patients have pregnancy hormone level checked at Day 0 and Day 7 to see if treatment has worked. The investigators plan to use a point of care test machine to see if it is possible to check pregnancy hormone level earlier than Day 7.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Positive pregnancy test
Less than six weeks gestation based upon Last Menstrual Period (LMP)
No evidence of definite intrauterine pregnancy on ultrasound
No signs or symptoms or significant risk factors for ectopic
Disqualifiers
Pain and/or bleeding
Significant risk factors for ectopic (previous ectopic, sterilisation, tubal disease, intrauterine device in situ)
Suspicious features for ectopic on ultrasound (adnexal mass, moderate free fluid)
Unable to provide blood sample
Trial population
Those having an abortion who meet the currently accepted clinical criteria for very early medical abortions.
Trial design
Cohort
Prospective
Treatments tested in this trial
Blood test
Diagnostic testPatients will undergo one additional blood test than is usual with standard care, to measure Human Chorionic Gonadotropin (HCG) level which will be analysed on a point of care test machine and in the lab
Participant Questionnaire
Other interventionThe investigators will administer participant questionnaires to both staff and patients to understand opinions on the point of care test machine
Treatment groups
Trial outcomes
Primary outcomes
Sensitivity
Sensitivity of percentage change in Human Chorionic Gonadotropin (HCG) between Day 0 and Day2-4 compared with percentage change in Human Chorionic Gonadotropin (HCG) between Day 0 and Day 7
Specificity
The Specificity of percentage HCG drop between Day 0 and Day 2-4, compared with specificity of percentage HCG drop between Day 0 and Day 7
Secondary outcomes
Usability questionnaire for Human Chorionic Gonadotropin (HCG) POCT verification using Likert scale.
Assess how useful, easy to use, easy to learn to use and acceptable the point of care test is to staff members. Scale will be a minimum of 1 and maximum of 5, with 1 relating to strongly disagree and 5 relating strongly agree to a range of positive statements, meaning a higher score would be a better outcome
Positive Predictive Value (PPV)
PPV for complete abortion of the HCG results between Day 2 and Day 4
Negative Predictive Value (NPV)
NPV for complete abortion for HCG results day 2-day 4
Binary Outcome
Whether the patients preferred follow up on Day 2-4 or on Day 7
