The EndoConnect platform showed excellent usability and engagement, improving pain, adherence, knowledge, and anxiety while reducing diagnostic delays in Brazilian primary care, and a new ethical AI framework was proposed.

This formative pilot study developed and deployed EndoConnect Alpha, an offline-capable digital health platform for endometriosis education, symptom tracking, moderated community support, and privacy-by-design AI-assisted tele-ultrasound triage in Brazilian SUS primary care units in Ceará, enrolling 60 participants (45 women aged 18–45 with suspected/confirmed endometriosis and 15 primary care professionals) over 8 weeks. Using usability (System Usability Scale), acceptability (Technology Acceptance Model), engagement analytics, and pre/post outcomes including pelvic pain VAS, EKES-15 knowledge, GAD-7 anxiety, adherence, and referral rate, the authors found high usability and acceptability (mean SUS 88.9; TAM 91.4%) alongside improvements in pain, knowledge, anxiety, adherence, and referral rates, with the largest benefits in rural and historically underserved subgroups. A key limitation is the formative, quantitative cross-sectional design with a small sample and lack of a clinical trial framework (trial not applicable), limiting causal inference about clinical impacts. This paper is centrally about endometriosis—feasibility and equity impacts of the EndoConnect platform and its NAM-Endora ethical AI governance framework in Brazilian primary care.

Abstract

BACKGROUND Endometriosis affects ≈10% of reproductive-age women worldwide (≈190 million) and is marked by debilitating chronic pain and infertility. In Brazil’s public health system (SUS), diagnostic delays average 7–10 years, disproportionately affecting low-income, rural, Black, and Indigenous women. OBJECTIVE This formative study aimed to (1) develop and deploy EndoConnect Alpha—an offline-capable progressive web app integrating evidence-based education, symptom tracking, moderated community support, and privacy-by-design AI-assisted tele-ultrasound triage—in SUS primary care units in Ceará, Brazil; (2) evaluate usability, acceptability, engagement, and preliminary clinical-psychosocial impact; and (3) propose the NAM-Endora Framework for ethical AI governance in low- and middle-income countries (LMICs). METHODS Applied methodological study with quantitative cross-sectional formative design (January 2024–November 2025). After expert validation and software registration (INPI BR5120250005556-0), 60 participants (45 women aged 18–45 years with suspected/confirmed endometriosis and 15 primary care professionals) were recruited from 10 SUS units (60% rural). Usability (System Usability Scale), acceptability (Technology Acceptance Model), engagement (Firebase Analytics), and pre/post outcomes (pain VAS, EKES-15 knowledge, GAD-7 anxiety, adherence, referral rate) were assessed over 8 weeks. Ethics approval: CAAE 82094924.8.0000.5049. RESULTS Mean SUS score 88.9 ± 9.8 (excellent); TAM 91.4%. Trail completion 79%; mean daily use 17.2 minutes. Significant improvements: pelvic pain −23% (P=.02), adherence +17% (P=.01), knowledge +21% (P<.001), anxiety −14% (P=.04), referrals +15% (P=.04). Largest benefits observed in rural, low-education, Black/Brown/Indigenous subgroups. The NAM-Endora Framework is proposed as the first LMIC-tailored ethical AI governance model. CONCLUSIONS EndoConnect Alpha is feasible and equity-enhancing in SUS primary care. The NAM-Endora Framework provides a novel, replicable model for responsible AI deployment in LMICs, with potential to reduce the global burden of endometriosis. CLINICALTRIAL Not applicable
