Timing, Delays And Pathways To Diagnosis Of Endometriosis: A Scoping Review Protocol

Introduction Pathways to diagnosis for women with endometriosis are frequently characterised with delays. Internationally, women face significant barriers and times to diagnosis. The prolonged time without a diagnosis may result in treatment delay, with clinical implications of chronic pain and an unknown effect on fertility outcomes. As delays in diagnosis extend, those suffering from endometriosis incur more cost and frequently experience a reduction in quality of life. The scoping review described in this protocol will (1) map current international scientific peer-reviewed and grey literature investigating pathways, timing, and delay of diagnosis of endometriosis, (2) define common concepts used in the literature, and (3) identify gaps for future examination and intervention development. Methods and analysis This protocol outlines a scoping review to investigate the current research focused on pathways, timing, and delays in endometriosis diagnosis. The scoping review uses the Joanna Briggs Institute Methodology. The researchers applied the Population, Concept, Context approach to form the research questions. A search string of key terms and Medical Subject Headings will be used to systematically search the PubMed, CINAHL, EMBASE, Web of Science, and Cochrane databases. We will also search ClinicalTrials.gov and grey literature sources. The original search was performed in July 2020, and it will be rerun prior to the manuscript submission. Finally, the reference lists of included works will be reviewed for additional studies. The search results will be screened and reviewed according to predetermined inclusion and exclusion criteria. Data will be extracted from the studies identified for final inclusion using a predetermined tool. The resulting data will be analysed to report the state of the science. Ethics and dissemination The proposed scoping review does not require review or approval by an ethical board. The researchers will disseminate the study results via conference presentations and publication in a peer-reviewed journal.
