Plain English Summary

Background and study aims:
We are carrying out a study of 3000 pregnant women with pre-eclampsia (high blood pressure, fluid retention and protein in the urine (proteinuria) in pregnancy) by collecting urine and comparing different diagnostic tests to find the most appropriate and effective method that predicts pre-eclampsia and its severity is needed to provide these women with the best possible care. Our aim is to find the most efficient assessment tool for diagnosing pre-eclampsia.

Who can participate?
Pregnant women, aged between 18 and 45 years of age from participating hospital trusts across England.

What does the study involved?
Participants will be invited to give a small urine sample when screened for pre-eclampsia, following 24 hour urine collection and at delivery. Woman will be asked to allow the researcher access to clinical data about them and their baby. At the end of the study the urine samples will be analysed in a laboratory using the current standard techniques for identifying pre-eclampsia.

What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part, but the findings from the study should benefit to future women who have suspected pre-eclampsia. This study may also help the NHS to develop more cost effective diagnosis techniques. There are no known risks to the patients taking part.

Where is the study run from?
Newcastle Upon Tyne Hospitals NHS Trust in collaboration with Newcastle University.

When is the study starting and how long is it expected to run for?
Recruitment will start beginning of November 2012 and participants will be enrolled on the study for a period of their pregnancy.

Who is funding the study?
NIHR Health Technology Programme and Newcastle University

Study information

Scientific title

Spot protein creatinine ratio (SPCr) and spot albumin creatinine ratio (SACr) in the assessment of pre-eclampsia: a diagnostic accuracy study with decision analytic model based economic evaluation and acceptability analysis



Study hypothesis

Investigations aimed at determining which method of measurement and which diagnostic thresholds are the most accurate in predicting not just preeclampsia but the clinical significant outcomes which will help inform clinicians on the correct clinical management of gestational hypertensive disorders during pregnancy. This in turn will improve the clinicians ability predict maternal and fetal outcomes.

Primary outcome measures

To evaluate the diagnostic accuracy of Point of care and laboratory assessments of Spot Protein Creatine Ratio (SPCr) and Spot Albumin Creatine Ratio (SACr) compared with 24 hour urine protein measurement at different thresholds in diagnosing and predicting severe Pre-Eclampsia (PE).

Secondary outcome measures

1.To Assess the accuracy of point of care assessments of SPCr and SACr at different thresholds in diagnosing PE compared to 24 hour Urine Protein Measurement.
2.To identify the most accurate Laboratory assay method of 24 hour proteinuria in assessment of PE
3. To estimate the accuracy of both quantitative and point of care assessments of SPCr and SACr at different thresholds in predicting adverse fetal outcomes.
4. To Develop a decision analytic model to estimate the diagnostic utility potential of replacing the 24 hour protein with the SPCr or SACr.
5. To assess the cost effectiveness of SPCr or SACr in comparison to the 24 hour urine protein measurement.

Participant inclusion criteria

1. Pregnant Women aged between 16- 45 years
2. More than 20 weeks gestation with confirmed gestational hypertension (systolic BP >140 mmHg and diastolic BP >90 mmHg)
3.Trace or more proteinuria on automated dipstick urinalysis. This is below the threshold of 1+ considered "test positive" by NICE and will thus allow exploration of the lower threshold for the index tests, i.e. below 300 mg/l protein.
4. Ability of give informed consent
