What "social risk factors and/or social determinants of health on costs and other economic burdens incurred by patients, caregivers and other stakeholders" are acceptable?

We encourage data collection and analyses that would enhance the understanding of heterogeneity in costs and economic burdens by a range of social factors including, but not limited to, patients’ insurance status income levels; geography, such as rural/urban differences; and race/ethnicity. In addition to social risk factors, awardees may also collect data and analyze heterogeneity in costs and economic outcomes by clinical factors such as illness severity, multi-morbidity, etc. These are examples; awardees can propose any data that they can justify as explaining heterogeneity in the costs and economic outcomes proposed in the supplement.
