Purpose The National Institutes of Health (NIH) has issued a Request for Information (RFI) to gather input from the scientific community, health professionals, professional societies, patient advocates, data standards experts and the public to inform the development of Common Data Elements (CDEs) for menopause-related data collection across research, clinical care, and health-system settings. Menopause CDEs will standardize questions and defined response options to support the robust collection of data on issues related to women's midlife health. Background Menopause is a normal, universal life stage marked by the permanent cessation of menstrual cycles following an aging-related decline in female reproductive hormones. More than one million women in the United States enter menopause each year, typically between ages 50 and 51. However, menopause can occur earlier, including among women who undergo certain medical procedures, such as hysterectomy, with approximately 12% entering menopause before the typical age range. The menopausal transition is associated with changes in menstrual patterns, hormone profiles and significant physiologic, biological, psychosocial changes affecting quality-of-life. Women experience substantial variability in the type, severity, and duration of symptoms, which are closely linked to the increasing burden of chronic disease after menopause. This heterogeneity underscores the importance of evidence-based treatment for symptoms and access to high-quality care tailored for women with different needs and within varying contexts. Thus, more research and systematically collected real-world information is necessary to best understand how to treat menopausal symptoms. This information is essential for understanding the short and long-term impact of those treatments on women's health and wellbeing. However, differences in data collection, outcome definitions, and reporting standards limit the ability to compare, combine, and reuse data across studies, clinical care, and health-system settings. Developing standardized Menopause CDEs would improve rigor, reproducibility, interoperability, and data sharing across clinical, epidemiologic, and translational research. CDEs are standardized, precisely defined questions paired with a set of specific allowable responses, used systematically across different sites, studies, demographics, or clinical trials and applicable within clinical, healthcare, and public-health settings to ensure consistent data collection ( https://cde.nlm.nih.gov/home). Implementation of CDEs promotes data interoperability, quality, reproducibility, efficiency of collection and efficiency of use across research platforms (e.g. different sites, studies or clinical trials) and within health-system workflows. Biomedical data are collected in different ways and formats across studies and routine clinical practice, making them difficult to share and combine; the use of CDEs standardizes how data are organized and defined so they can be more easily shared and used together. CDEs can be connected across shared data models and standard healthcare vocabularies, such as SNOMED CT, LOINC, UMLS, and others catalogued in public repositories, such as the National Library of Medicine's Value Set Authority Center. This connection helps research data align with real-world information from electronic health records, health insurance claims, wearable devices, and patient-reported outcomes, supporting research, clinical documentation, and clinical decision-making. This is especially important for menopause research because symptoms, treatments, and related health conditions are often recorded in different ways across clinical care, surveys, and research studies which make it difficult to compare findings or combine data. Using CDEs helps ensure these data can be compared and combined accurately to better understand women's midlife health. Menopause affects quality of life, daily functioning, emotional well-being, social relationships, and work productivity. Menopause CDEs should therefore incorporate patient-reported outcomes and other measures that reflect women's lived experiences across research, clinical care, and public health settings. Broader use of Menopause CDEs across HHS, including in population-based surveys such as CDC's National Health Interview Survey (NHIS), can promote more consistent data collection and improve coordination and data sharing across agencies. NIH recognizes the continued need to develop common data CDEs related to women's health that will help researchers, clinicians, healthcare professionals, patients and communities share and combine datasets, promote interoperability, and improve the accuracy of datasets when it comes to women's health. Although a number of validated menopause-related surveys, instruments, and measures already exist, including but not limited to Menopause Quality of Life (MENQOL) questionnaire, the Greene Climacteric Scale (GCS), Menopause Rating Scale (MRS), Hot Flash Related Daily Interference Scale (HFRDIS/HFI), Female Sexual Function Index (FSFI), Female Sexual Distress Scale (FSDS/FSDS-R), and the DIVA sexual health subscale, their use remains fragmented across research studies, clinical care, and population-based surveys. The lack of consistent standardization, harmonization, and mapping to common data frameworks limits interoperability and the ability to compare, combine, and reuse data across settings. NIH has successfully implemented CDE frameworks in other research domains, including maternal health, and seeks to build on these efforts by developing, with community input, a menopause-specific CDE structure that is patient and community informed, flexible, and aligned with existing standards where appropriate. These CDEs will support NIH's development of a data resource that better coordinates and integrates investments in women's health research across NIH. This RFI seeks feedback on the development and implementation of Menopause CDEs including a set of minimal core CDEs, supplementary CDEs and exploratory CDEs. This RFI also seeks feedback to develop guidance and tools that make Menopause CDEs easier to use and improve the ability to combine and integrate data collected with Menopause CDEs. Information Requested The purpose of this RFI is to solicit input on priorities, scope, and considerations for the development and implementation of Menopause CDEs. Responses will help inform NIH's approach to structuring CDE domains, identifying key data elements, and engaging relevant communities. NIH seeks input, including from patients, patient advocates, and support organizations, on what information is most important to collect about menopause, and why it matters, and how to involve patients in the initial development and testing of CDEs to ensure they reflect a wide range of research needs, clinical contexts, lived experiences and health-system priorities. This RFI seeks input on standard terminologies and metadata to inform the development of menopause CDEs. It does not propose a data repository or request the submission of patient or research data.
