Aims: To document the frequency of conventional and complementary treatments used by Australian women with endometriosis and the perceived efficacy of these treatments, and to qualitatively explore women’s treatment satisfaction. Background: We do not adequately understand whether Australian women with endometriosis are satisfied with their medical care. Methods: Using a mixed-methods design, 532 women with self-reported endometriosis were recruited from the community. Participants were asked about their medication, complementary and self-care treatment use, as well as perceived efficacy on a 0 (not effective) to 10 (extremely effective) numeric rating scale, and open-ended qualitative survey items about treatment satisfaction. Results: Ninety-seven percent of women used medication for pain relief (mean perceived efficacy = 5.05) and 89% used complementary/self-care strategies (mean perceived efficacy = 3.70), with medication rated as significantly more effective (P < 0.001). Content analysis of the qualitative data identified that 36% of women were dissatisfied with treatment, 34% were somewhat satisfied and 24% were satisfied. We identified qualitative themes relating to: (i) barriers to treatment, which included lack of access, stigma and disappointment with medical professionals who were perceived as uncaring, unhelpful and, in some cases, psychologically damaging; (ii) the need for holistic, interdisciplinary care; and (iii) patient knowledge, advocacy and resilience in endometriosis management. Conclusions: Our findings reveal important limitations in the current Australian healthcare model, including the need for patient-centred interdisciplinary care that treats the biopsychosocial needs of people with endometriosis, and widespread pain education, spanning medical training to community awareness.
