Polyendocrine Metabolic Ovarian Syndrome (PMOS), previously known as Polycystic Ovary Syndrome, is an endocrine disorder affecting 10-13% of reproductive-aged individuals with ovaries. PMOS is characterised by distinctive pathophysiology features, such as insulin resistance, which overlaps with the risk profiles for Type 2 Diabetes (T2D) and cardiovascular disease. Lifestyle management is the first-line treatment for PMOS for improving cardiometabolic, reproductive, and psychological features1. Diabetes Victoria Life! program facilitators and Credentialled Diabetes Educators (CDEs) are key healthcare professionals (HCPs) well positioned to expand their skillset from the diabetes workforce into a broader metabolic workforce to support individuals with PMOS. However, individuals with PMOS continue to receive limited condition-specific, personalised lifestyle management support due to gaps in HCPs’ knowledge, confidence, and preparedness to provide individualised, evidence-based care2. This qualitative study aimed to co-design an eLearning module to strengthen HCP knowledge and confidence in delivering tailored lifestyle strategies for individuals with PMOS, particularly for T2D risk reduction. Interactive co-design workshops were held via Zoom, audio-recorded and transcribed. Qualitative data from these workshops were analysed using framework thematic analysis, informed by the Template for Intervention Description and Replication (TIDieR) framework, the Theoretical Domains Framework, and the Capability, Opportunity, Motivation and Behaviour (COM-B) model to guide intervention development and provide robust analysis. Seventeen participants including six HCPs (Accredited Practising Dietitians, Accredited Exercise Physiologists, and Registered Nurses), six individuals living with PMOS, and five HCPs who also lived with PMOS, took part in three co-design workshops (one on course design and two on course content). Participants identified priorities across two domains: course design and course conte nt. Four themes informed course design: (1) flexible, self-paced, diverse learning modes; (2) evidence-based, weight-inclusive philosophy of care; (3) lived experience representation in content and imagery; and (4) translating content to diverse HCP clinical practice settings, professional credentialing and affordability. Four themes informed course content: (1) foundational evidence-based knowledge aligned with the 2023 International PCOS/PMOS Guidelines; (2) person-centred, individualised care; (3) addressing weight and gender stigma and structural barriers to access of care; and (4) practical consultation enablers, including lived-experience case studies. Across all themes, participants consistently emphasised the importance of individualised, destigmatising care, and the meaningful integration of lived experience to support effective clinical practice and translation into real life. These findings will directly inform the development of the proposed eLearning module. To effectively support HCPs’ knowledge and confidence in delivering evidence-based lifestyle care for individuals with PMOS particularly in relation to T2D risk reduction, eLearning initiatives should prioritise condition-specific education, individualised and destigmatising approaches applicable across diverse healthcare practice, and informed by lived experience. Embedding these elements may strengthen HCP knowledge and confidence to provide tailored support for T2D risk reduction and broader PMOS care.
