Overview
Classify patients into risk tiers based on clinical complexity, utilization patterns, social determinants, and predicted outcomes using validated risk stratification methodologies. This skill supports population health management, care management resource allocation, and value-based care program design by identifying which patients need which level of intervention.
When to Use
Building risk-stratified patient panels for care management programs
Prioritizing high-risk patients for proactive outreach
Allocating care management resources based on patient acuity
Supporting ACO/value-based care population segmentation
Identifying rising-risk patients before they become high-cost
Designing tiered intervention programs based on risk levels

Ocupación Clinical profile Active diagnoses (ICD-10), medications, labs Structured arrays
Utilization history ED visits, admissions, office visits (12-24 months) Structured array with dates
Claims/cost data Total cost of care, cost by category Numeric
SDOH indicators Housing, food security, transportation, social support Structured object
Functional status ADL/IADL scores, cognitive status if available Structured object
Methodology
Step 1: Clinical Complexity Scoring Calculate disease burden and clinical complexity:
HCC (Hierarchical Condition Category) Risk Score:
Map active ICD-10 diagnoses to HCC categories
Calculate CMS-HCC risk adjustment factor (RAF)
Benchmark against population average (1.0)
Higher RAF = higher predicted cost and clinical complexity
Charlson Comorbidity Index (CCI):
Score comorbidities: MI, CHF, PVD, CVD, dementia, COPD, connective tissue disease, PUD, liver disease, diabetes, hemiplegia, CKD, cancer, AIDS
Each condition scores 1-6 based on severity
Total CCI predicts 10-year mortality risk
Elixhauser Comorbidity Measure:
31 comorbidity categories beyond Charlson
Captures conditions like depression, obesity, drug abuse, psychoses
Better predictor for in-hospital mortality and LOS
Step 2: Utilization Pattern Analysis Evaluate healthcare utilization intensity:
Metric Low Risk Moderate High Very High ED visits (12 mo) 0-1 2-3 4-5 6+ Inpatient admits (12 mo) 0 1 2-3 4+ Specialists seen 0-2 3-4 5-7 8+ Total cost of care Below 50th pctl 50-75th pctl 75-90th pctl Above 90th pctl Readmissions (30-day) None 1 2+ Multiple
Step 3: Social Risk Assessment Evaluate social determinants that amplify clinical risk:
SDOH Risk Factors (scored 0-2 each):
Housing instability or homelessness (0=stable, 1=at risk, 2=unstable)
Food insecurity (0=secure, 1=low security, 2=very low)
Transportation barriers (0=none, 1=occasional, 2=frequent)
Social isolation (0=connected, 1=limited, 2=isolated)
Health literacy (0=adequate, 1=limited, 2=low)
Financial strain (0=stable, 1=some stress, 2=severe)
Total SDOH score: 0-12 (Low: 0-3, Moderate: 4-7, High: 8-12)
Step 4: Composite Risk Tier Assignment Combine clinical, utilization, and social scores into a composite tier:
Risk Tier Clinical Utilization SDOH Recommended Intervention Level Tier 1 - Healthy/Low Low CCI, few conditions Minimal utilization Low SDOH risk Prevention and wellness Tier 2 - Rising Risk Moderate CCI, chronic conditions emerging Increasing utilization Low-Moderate SDOH Disease management, self-management support Tier 3 - High Risk High CCI, multiple chronic conditions Frequent utilization Moderate-High SDOH Care management, care coordination Tier 4 - Complex/Very High Very high CCI, frailty, functional decline Very frequent utilization High SDOH Intensive care management, multidisciplinary team
Step 5: Actionable Segmentation Assign patients to intervention programs based on tier and dominant risk drivers:
Tier-Based Program Mapping:
Tier 1: Preventive outreach, annual wellness visits, gap closure
Tier 2: Chronic disease education, medication management, care gap alerts
Tier 3: Assigned care manager, regular check-ins, transition management
Tier 4: Intensive care team (RN + SW + pharmacist + CHW), home visits, high-touch coordination
Output Specification patient_profile : demographics, insurance, pcp assignment
clinical_complexity : hcc_raf_score, charlson_cci, active_conditions_count, medication_count, high_risk_conditions list
utilization_profile : ed_visits_12mo, admissions_12mo, readmissions, specialist_count, total_cost_of_care, cost_percentile
sdoh_assessment : individual factor scores, total_sdoh_score, sdoh_risk_level
composite_stratification : risk_tier (1-4), tier_label, composite_score, dominant_risk_domain, confidence_level
intervention_assignment : program_name, intervention_level, recommended_team_composition, key_focus_areas, engagement_frequency
rising_risk_indicators : flags for patients trending toward higher tier (increasing utilization, new diagnoses, SDOH changes)
Analysis Framework
Impactability Assessment Not all high-risk patients are equally impactable. Assess:
Modifiable risk factors present : Can interventions change the trajectory?Patient engagement likelihood : History of appointment adherence, responsivenessIntervention availability : Are appropriate programs and resources available?Cost-effectiveness : Will intervention costs be offset by utilization reduction? Impactability Score: High (good candidate for intensive program), Medium (moderate intervention), Low (maintain monitoring, fewer modifiable factors)
Trend Analysis Track tier movement over time:
Improving : Moving to lower risk tier (intervention success indicator)Stable : Remaining in same tier (maintenance mode)Worsening : Moving to higher tier (intervention escalation needed)Rising risk : Not yet high tier but trending upward (early intervention opportunity)
Examples Input : 72-year-old male, CHF (EF 35%), DM2 with neuropathy, CKD Stage 3a, depression. On 12 medications. 3 ED visits in 12 months, 2 hospital admissions (1 readmission). Lives alone in rural area. Limited transportation. Income below 200% FPL.
Clinical: HCC-RAF 2.4 (high), CCI 6 (high), 4 active chronic conditions, polypharmacy
Utilization: 3 ED, 2 admits, 1 readmission — HIGH
SDOH: Social isolation (2) + transportation (2) + financial (2) = 6/12 — MODERATE
Composite: Tier 4 - Complex/Very High
Dominant driver: Clinical complexity + utilization intensity
Recommended: Intensive care management team with home health, telemonitoring, community health worker for transportation, pharmacist for medication management
Guidelines
Stratification is dynamic — reassess at least quarterly or after significant clinical eventsAvoid label bias — risk tiers inform resource allocation, not patient worthInclude rising-risk identification — intervening before patients become high-risk is most cost-effectiveValidate models against outcomes — regularly calibrate stratification against actual utilization and costsEnsure equity — audit stratification for demographic bias and disparities
Validation Checklist
HIPAA Compliance Notes
Risk stratification data aggregates extensive PHI and requires strict access controls
Share stratification results only with care team members with a need to know
De-identify population-level stratification reports for quality improvement
SDOH data may have additional privacy requirements under state law
Patient consent should be obtained before enrolling in care management programs based on stratification
Maintain audit logs for all stratification data access and sharing
