§ 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
