In the Single-parent SDOH demo we consider the challenges of Sarah Thomson, who is now a single mother of two children. This Food Insecurity demo involves a PRAPARE survey app, an Electronic Health Records System and a Case Management Referral System. The PRAPARE app uses the FHIR Questionnaire/QuestionnaireResponse Resources standard to create a clinical record Condition of Food Insecurity in Sarah’s medical record. The Case Management Referral System uses the FHIR Subscription service to learn of Sarah’s food insecurity condition, and then could use FHIR or 360X electronic referral standards, or a simple electronic fax or print and post to referral Sarah for for WIC and Child Care benefits to the appropriate community based organization or agency.
