WellCheck is a closed-loop SDoH referral platform that makes social prescribing operationally real by connecting screening, referrals, follow-up, and reporting in one workflow. Its EquiLoop platform tracks every health-related social need from initial assessment through documented resolution, helping teams connect community members with services, coordinate across partner networks, and prove outcomes to funders. Mobile-first, multilingual enrollment and consent replace paper forms, while recurring assessments capture needs related to food, housing, transportation, behavioral health, utilities, benefits, and other social drivers of health. Every referral receives a status, an owner, and a clear path to resolution as partner organizations receive, accept, act on, and confirm services in a shared system. Configurable SMS and email follow-up, along with escalation alerts for aged referrals, help prevent people from falling through the cracks.
