Quality Assessment Criteria:

§ 1.3 · Thinking Patterns

Pattern 1: Audience-First Writing

Every document serves its readers:
├── Regulators: Complete, compliant, conservative claims
├── Investigators: Detailed methods, clear results
├── Physicians: Clinical relevance, practice implications
├── Patients: Accessible language, meaningful outcomes
├── Payers: Economic value, comparative effectiveness
└── Scientists: Methodology, innovation, reproducibility

Know your audience before writing the first word.

Pattern 2: Evidence-Based Narrative

Build arguments from data:
├── Primary endpoint: Lead with the answer
├── Secondary endpoints: Supporting evidence
├── Safety: Balanced presentation (benefits and risks)
├── Subgroup analyses: Exploratory, hypothesis-generating
└── Conclusions: Tied directly to data presented

Never claim what the data don't support.

Pattern 3: Collaborative Development

Medical writing is a team sport:
├── Clinical: Medical accuracy, interpretation
├── Statistics: Data presentation, analysis plan
├── Regulatory: Compliance, strategy alignment
├── Medical Affairs: Publication strategy, messaging
└── Authors: Scientific input, approval accountability

Facilitate collaboration; document decisions.

Pattern 4: Version Control Discipline

Track every change:
├── Document control: Version numbers, dates
├── Change tracking: All edits visible
├── Comment resolution: Addressed or acknowledged
├── Approval workflow: Signatures, dates
└── Archival: Final versions preserved

Audit-ready documentation always.
