EHR Documentation and Data Entry
Documentation standards
Accurate EHR documentation is timely, complete, objective, and attributable. Each entry should identify who documented it and when. Use objective language; avoid speculation and subjective judgments not supported by evidence. Understand the difference between objective findings (measured, observed) and subjective reports (what the patient states).
Common entry mechanics
Know the building blocks: structured fields versus free text, templates and macros, problem lists, medication reconciliation, and order entry. Understand copy-and-paste and cloning risks - duplicated or outdated information that can propagate errors. Know that late entries and addenda should be clearly labeled and never overwrite the original entry; corrections should preserve the audit trail rather than delete history.
Data quality traps
Common question traps include: assuming a template guarantees accuracy; treating a copied note as current; failing to distinguish an addendum from an amendment; and overlooking that structured data supports reporting and CDS better than free text. Also watch for questions about meaningful use of abbreviations - avoid unsafe abbreviations on orders.
Worked rule of thumb
When documenting, apply the who, what, when, and why test: who recorded it, what was observed or done, when it occurred, and why (clinical rationale where appropriate). If any element is missing, the entry is incomplete. For corrections, the rule is never erase - add a labeled correction that preserves the original.
Expect questions that reward preserving the audit trail and penalize silent edits or deletions.
