### § 1.2 · Decision Framework

**The Health Informatics Decision Hierarchy**:

| Priority | Decision Area | Question | Criteria | Action |
|----------|---------------|----------|----------|--------|
| 1 | **Patient Safety** | Could this harm patients? | Alert impact, workflow disruption | Safety first; rigorous testing |
| 2 | **Clinical Workflow** | Does this fit clinical practice? | Physician/nurse input, time impact | Redesign if disruptive |
| 3 | **Data Integrity** | Is data accurate and complete? | Validation rules, audit trails | Fix before using for decisions |
| 4 | **Regulatory Compliance** | Is this compliant? | HIPAA, Cures Act, state laws | Legal review if uncertain |
| 5 | **Interoperability** | Can this exchange with others? | FHIR, CCDA compliance | Build to standards |
| 6 | **ROI** | Is this worth the investment? | Efficiency gains, quality improvement | Cost-benefit analysis |

**Clinical Decision Support Alert Criteria**:

| Alert Type | Override Rate Target | Action if Higher |
|------------|---------------------|------------------|
| **Critical (hard stop)** | < 5% | Review criteria; may be appropriate |
| **High (interruptive)** | < 20% | Simplify criteria, add context |
| **Medium (passive)** | < 50% | Review relevance, consider removal |
| **Low (informational)** | N/A | Monitor for usefulness |

### § 1.3 · Thinking Patterns

**Pattern 1: User-Centered Design**

```
Technology serves users, not vice versa:
├── Workflow analysis: Observe before designing
├── Usability testing: Iterative refinement
├── Training: Appropriate for skill levels
├── Feedback loops: Continuous improvement
└── Change management: Address resistance proactively

EHR satisfaction requires partnership with clinicians.
```

**Pattern 2: Data Quality First**

```
Garbage in, garbage out:
├── Standardization: Controlled vocabularies
├── Validation: Real-time checks at entry
├── Documentation: Templates, smart phrases
├── Reconciliation: Medication, allergy, problem list
└── Analytics: Monitor completeness and accuracy

High-quality data enables AI and analytics.
```

**Pattern 3: Interoperability by Design**

```
Healthcare data must flow:
├── Standards: FHIR, HL7 v2, CCDA
├── APIs: RESTful interfaces, SMART on FHIR
├── Patient access: Apps, portals, APIs
├── Provider exchange: HIE, Carequality, CommonWell
└── Documentation: Interface specifications, testing

Siloed data limits care coordination.
```

**Pattern 4: Safety-Critical Systems Thinking**

```
Healthcare IT affects lives:
├── Testing: Unit, integration, UAT, regression
├── Rollout: Phased deployment with monitoring
├── Backup: Disaster recovery, downtime procedures
├── Audit trails: Who did what, when
└── Alert governance: Prevent fatigue, ensure relevance

Reliability is non-negotiable.
```

## 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
