### § 1.2 · Decision Framework

**The Public Health Analysis Priority Matrix**:

| Priority | Situation | Response Time | Actions |
|----------|-----------|---------------|---------|
| 1 | **Outbreak/Emergency** | Immediate | Alert leadership, rapid analysis, field deployment |
| 2 | **Unusual Cluster** | 24-48 hours | Detailed investigation, statistical testing |
| 3 | **Trend Analysis** | Weekly/monthly | Surveillance reports, dashboard updates |
| 4 | **Program Evaluation** | Quarterly/annual | Outcome assessment, recommendations |
| 5 | **Policy Analysis** | Project-based | Research synthesis, impact modeling |
| 6 | **Capacity Building** | Ongoing | Training, systems development |

**Data Quality Assessment**:

| Criterion | Standard | Action if Not Met |
|-----------|----------|-------------------|
| **Completeness** | > 90% | Data quality improvement plan |
| **Timeliness** | Within reporting window | Follow-up with reporters |
| **Accuracy** | < 5% error rate | Validation and correction |
| **Representativeness** | Population coverage | Weighting, imputation strategies |

### § 1.3 · Thinking Patterns

**Pattern 1: Population Perspective**

```
Focus on groups, not individuals:
├── Rates, not counts (account for population size)
├── Stratification: By age, race, geography
├── Trends over time: Secular changes, seasonality
├── Comparisons: Benchmarks, peer communities
└── Attribution: What explains differences?

Population health is more than the sum of individual health.
```

**Pattern 2: Social Ecological Model**

```
Health is determined at multiple levels:
├── Individual: Behaviors, genetics
├── Interpersonal: Family, social networks
├── Organizational: Workplaces, schools
├── Community: Neighborhood resources, norms
└── Policy: Laws, regulations, systems

Interventions must address multiple levels.
```

**Pattern 3: Health Equity Lens**

```
Examine all analyses for disparities:
├── Stratify by race/ethnicity, income, geography
├── Calculate disparity metrics (rate ratios)
├── Identify modifiable determinants
├── Prioritize vulnerable populations
└── Monitor equity alongside overall trends

Equity is not equality; it's justice in health.
```

**Pattern 4: Evidence-Based Decision Making**

```
Ground recommendations in science:
├── Best available evidence
├── Local context and data
├── Stakeholder input
├── Implementation feasibility
└── Evaluation plan

Good data + good analysis = good decisions.
```

## Workflow

### Phase 1: Triage
- Assess patient vital signs and chief complaint
- Identify immediate life threats
- Prioritize treatment order

**Done:** Triage complete, patient prioritized, urgent issues identified
**Fail:** Missed critical symptoms, incorrect prioritization

### Phase 2: Diagnosis
- Gather detailed history and perform examination
- Order appropriate diagnostic tests
- Analyze results with differential diagnosis

**Done:** Diagnosis established, differentials considered
**Fail:** Diagnostic errors, missed conditions, test delays

### Phase 3: Treatment
- Develop treatment plan per guidelines
- Obtain patient consent
- Implement interventions

**Done:** Treatment initiated, patient stable, consent documented
**Fail:** Treatment errors, patient deterioration, consent issues

### Phase 4: Follow-up
- Monitor treatment response
- Adjust plan as needed
- Provide patient education and discharge planning

**Done:** Patient discharged safely, follow-up arranged
**Fail:** Readmission risk, inadequate instructions, missed follow-up
