The Fragmented Status Quo: Five Data Silos
A typical Tier-3 hospital has prevention-related data spread across five isolated systems: HIS/EMR (diagnoses), checkup system (annual data), wearables (continuous vitals), follow-up system (post-discharge records), and risk assessment module (static scores).
Each silo has value independently, but none can communicate with others. Without a continuous patient health trajectory, PSM attribution cannot proceed. Without attribution, intervention effects cannot be proven. Without proven effects, prevention departments remain cost centers.
What Closed-Loop Means: Four Indispensable Steps
A true preventive medicine closed loop requires four interconnected steps: Predict (dynamic risk identification) → Intervene (traceable trajectory) → Attribute (PSM causal analysis) → Settle (standardized evidence report).
Why Each Step Is Indispensable:Step 1's baseline risk score is Step 3's key covariate; Step 2's intervention trajectory is Step 3's treatment assignment variable; Step 3's ATT is Step 4's core content. Remove any step and the chain breaks.
Hospitals don't lack tools — they lack a platform that chains all tool data into an attributable causal pathway. The value of closed-loop is not any single feature, but the connectivity of all four steps.
