care variation analysis notebook · cohort matrix
pathway drift by service line

Cohort drift stays readable for operator review.

This route turns statistical drift into service-line-specific action cues teams can use for care operations reviews, utilization briefings, and documentation cleanup packets.

Synthetic demonstration data only. No real patient data is included.
CV-14

Cardiology transitions

Actual LOS moved from 4.2 to 5.5 days while readmission drift hit 4.8 points.

Follow-up reliability is 71% against an expected 84%.

Escalate pathway review, reconcile handoff evidence, and tighten discharge-to-follow-up routing immediately.

CV-22

Orthopedic surgery

Actual LOS moved from 3.1 to 4.4 days while readmission drift hit 3.4 points.

Follow-up reliability is 80% against an expected 91%.

Escalate pathway review, reconcile handoff evidence, and tighten discharge-to-follow-up routing immediately.

CV-31

Oncology infusion

Actual LOS moved from 2.8 to 3.0 days while readmission drift hit 0.1 points.

Follow-up reliability is 86% against an expected 88%.

Maintain current pathway controls and preserve clean evidence on discharge and follow-up reliability.

CV-45

Primary care chronic

Actual LOS moved from 1.3 to 1.8 days while readmission drift hit 3.4 points.

Follow-up reliability is 69% against an expected 79%.

Escalate pathway review, reconcile handoff evidence, and tighten discharge-to-follow-up routing immediately.
