 The JAMA Internal Medicine 2024 RCT testing intensive food-as-medicine intervention (10 meals/week + education + coaching for 1 year) found NO significant difference in HbA1c, hospitalization, ED use, or total claims between treatment and control groups. This challenges the assumption that SDOH interventions produce strong ROI—the RCT evidence shows null clinical outcomes despite addressing food insecurity directly.

+England's social prescribing provides international counterpoint: 1.3M annual referrals with 3,300 link workers represents the operational infrastructure that US SDOH interventions lack. However, UK achieved scale without evidence quality - 15 of 17 economic studies were uncontrolled, 38% attrition, SROI ratios of £1.17-£7.08 but ROI only 0.11-0.43. This suggests infrastructure alone is insufficient without measurement systems.

 Caregivers themselves become socially isolated as a direct consequence of caregiving responsibilities. With 63 million Americans providing an average 18 hours/week of unpaid care, and more than 13 million struggling to care for their own health, the caregiving role creates a structural pathway to social isolation. This compounds the $7B Medicare cost: not only are isolated elderly people costly, but the caregiving system creates new isolated individuals from the working-age population.

+England's social prescribing explicitly targets social isolation through link workers connecting patients to community resources. 60% of patients were female, 23% ethnic minorities, with deprived area representation increasing from 23% to 42% (2017-2023). Service refusal declined from 22% to 12%, suggesting acceptability. However, researchers note rollout 'has NOT been sufficiently targeted at areas with highest need' despite equity gains.

 PRIMARY CONNECTION: medical care explains only 10-20 percent of health outcomes because behavioral social and genetic factors dominate as four independent methodologies confirm
 WHY ARCHIVED: First international health system evidence for Vida's KB (addresses Frontier Gap 2). The scale-vs-evidence tension challenges the assumption that non-clinical interventions just need more funding — they may also need better measurement.
