How we define recurrent miscarriage matters: A qualitative exploration of the views of people with professional or...

Recurrent miscarriage (RM) affects 1%-3% of women/couples of reproductive age depending on the definition used, for example, whether 2 or ≥3 miscarriages. Stakeholders' views of how RM is defined have received limited attention to date. A definition reflects the medical evidence and values of a society at the time, and thus warrants ongoing review.

We aimed to explore the views of women and men with lived experience of RM, and those involved in the delivery/management of services and supports, on how RM is and/or should be defined.

We adopted a qualitative study design, incorporating semi-structured interviews. We used purposive sampling to recruit participants in the Republic of Ireland, ensuring diverse perspectives were included. Women and men with lived experience of ≥2 consecutive first-trimester miscarriages were recruited via health professionals and social media; other participants via the research team's networks. Interviews were audio-recorded, transcribed, pseudo-anonymized and analysed using reflexive thematic analysis.

We conducted interviews with 42 health professionals/service providers and 13 women and 7 men with lived experience of RM (June 2020 to February 2021). We generated three interrelated themes from the data: (i) The need for a standardized definition of recurrent miscarriage-Finding a balance between research evidence, individual needs and healthcare resources, (ii) The definition is a route to finding an answer and/or validating women/couples' experience of loss and (iii) Working around the definition-Advocacy and impacts.

A nuanced approach to defining RM is warranted, one which is evidence-informed recognizes the individual needs of women/couples, and considers healthcare resources.

Members of the multidisciplinary RE:CURRENT (REcurrent miscarriage: evaluating CURRENT services) Project Research Advisory Group (including four parent advocates, two of whom are co-authors on this article) were actively involved throughout the study, including the generation of topic guides and the refining of themes.
