Towards reducing diagnostic delay in endometriosis in primary care: a qualitative study.

Background: Due to a heterogeneity of symptoms, a lack of an adequate diagnostic test, and a lack of awareness, diagnostic delay in endometriosis in primary care on average amounts to 35 months.

Aim: To determine which interventions are most feasible to reduce time to diagnosis in primary care, focusing on GPs' preferences, the intervention's content, design, and implementation.

Design & Setting: We conducted a qualitative study by performing focus groups with GPs and GP trainees between July and October 2021.

Method: Data collection was continued until saturation was obtained. Focus groups were transcribed and openly encoded. Themes were formulated by three independent researchers.

Results: Divided over five focus groups 22 GPs and 13 GP trainees participated. Three themes were formulated: increasing awareness, combined intervention, and reaching unaware GPs. Suggestions for a combined intervention strategy were adaptation of guidelines, a diagnostic support tool, and compulsory education. To reach unaware GPs, participants felt that education should be offered in regional networks and education for GP trainees should be mandatory. A guideline on menstrual symptoms should be considered and the term endometriosis should be added to the differential diagnosis paragraphs of existing guidelines. A diagnostic support tool should be linked to a guideline and consist of a flowchart with steps starting with the first presentation of symptoms leading to the diagnosis of endometriosis.

Conclusion: According to GPs, a combined intervention strategy consisting of an adapted guideline, a diagnostic support tool, and education might be successful interventions in reducing diagnostic delay in endometriosis.
