About
To further develop a patient care pathway (incorporating a statistical model which uses the values of biomarkers) in routine clinical practice that will aid the diagnosis and management of women with an ectopic pregnancy.
Full description
Purpose and design-There is a need for the patient care pathway to evolve in order to aid and improve the diagnosis and management of women with a pregnancy of unknown location (PUL) and ectopic pregnancy (EP). There is potential for this to be achieved by the incorporation of a statistical model that uses one or more novel markers identified by this study. These markers may replace or add to the effectiveness of markers used in the current statistical model.
Recruitment-200 patients. Inclusion: Patients attending the Early Pregnancy Unit (EPU) in the first trimester with a PUL or ectopic pregnancy on trans-vaginal ultrasound scan between the ages of 18-50 years. Exclusion: Patients diagnosed with cancer, presence of acute medical condition, patients aged less than 18 years, patients who cannot give fully informed study consent.
Consent - Posters will advertise the study. Patients in EPU will be invited to the study by a member of the clinical care team. Written consent will be required for all aspects of the study other than for 3-dimensional scanning of PUL and EP patients, where verbal consent will be obtained. Patients will be given at least 24 hours to consider whether they wish to participate.
Confidentiality - The Chief Investigator will preserve the confidentiality of participants taking part in the study and is registered under the Data Protection Act. Patient consent forms will be stored securely within the study file. All patient identifiable information, where required, will be stored electronically on National Health Service (NHS) approved computers, accessible only by personnel involved in the study via password.
Conflict of interest - None involved in the study have a conflict of interest.
Dissemination of results - No patient identifiable information will be included in the research report or publication. Anonymised results will be disseminated to scientific community by means of publication in peer-reviewed literature and presented at national and international meetings.
