## Content

Nationwide longitudinal observational study using Clinical Practice Research Datalink records from 1.2 million patients across 1,736 GP practices in England, tracking social prescribing trends 2019-2023.

Scale findings:
- 9.4 million GP consultations involved social prescribing codes (2019-2023)
- 5.5 million consultations led to social prescribing referrals
- 1.3 million patients referred in 2023 alone — exceeding original NHS 5-year target of 900,000 by 27-52%
- Over 3,300 link workers now employed across England
- Service refusal declined from 22% to 12% (2019-2023)

Equity impacts:
- 60% of patients offered social prescribing were female
- 23% from ethnic minority groups
- Representation from deprived areas increased from 23% to 42% (2017-2023)
- BUT: rollout has NOT been sufficiently targeted at areas with highest need

Healthcare utilization (from separate research):
- 28% average reduction in GP service demand post-referral (range: 2-70%)
- 24% average reduction in A&E attendance (range: 8-27%)
- However: one study found GP workload overall was NOT reduced despite patient-level improvements

Economic evidence (Frontiers 2026 systematic review, 18 studies):
- SROI ratios: £1.17 to £7.08 per £1 invested
- ROI estimates: only 0.11 to 0.43 per £1 invested (much lower)
- "Robust economic evidence on social prescribing remains limited"
- Standard health economic methods are "rarely applied"
- 15 of 17 studies were uncontrolled before-and-after designs
- Mean attrition rate: 38%

## Agent Notes
**Triage:** [CLAIM] — Social prescribing at national scale is the world's largest experiment in non-clinical health intervention, but the evidence quality is strikingly weak relative to the scale of implementation
**Why this matters:** The UK social prescribing experiment is the most important international test of whether non-clinical interventions work at population scale. The scale is extraordinary (1.3M referrals/year, 3,300 link workers). But the evidence base is surprisingly weak: mostly uncontrolled studies, 38% attrition, no standardized outcome measures.
**What surprised me:** The DISCONNECT between scale and evidence quality. England has implemented social prescribing for 1.3M patients/year but doesn't know if it works. This is the inverse of the CHW problem (strong evidence, low implementation). Social prescribing has massive implementation but weak evidence.
**KB connections:** [[medical care explains only 10-20 percent of health outcomes...]], [[SDOH interventions show strong ROI but adoption stalls...]], [[social isolation costs Medicare 7 billion annually...]]
**Extraction hints:** Two claim candidates: (1) "England's social prescribing program is the world's largest non-clinical health intervention reaching 1.3M patients annually but lacks the controlled evidence to validate its impact"; (2) "Social prescribing and CHW programs represent inverse failure modes — social prescribing scaled without evidence while CHW programs proved effectiveness without scaling"

## Curator Notes
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.
