No acute distress (NAD)
Formal Definition
A standard phrase in the physical examination documentation indicating that at the time of exam, the patient appears comfortable, alert, and free of acute symptoms requiring emergent intervention — part of "General Appearance" in the standard H&E template, often abbreviated "NAD" in progress notes; distinct from clinical stability (no acute distress does not mean no medical problems; the patient can have chronic illness and still be NAD at the moment).
How It's Used on the Ward
"NAD" — a quick way to document that, at this moment, the patient is not in visible distress; written at the top of the exam section, often with other general descriptors ("WDWN, NAD, AAOx3" — well-developed, well-nourished, no acute distress, alert and oriented to person/place/time); reassures the reader that the patient is not acutely decompensating right now.
Example
""GEN: Well-appearing elderly gentleman, well-developed and well-nourished, in no acute distress. AAOx3. Conversant, appropriate, looking at examiner when spoken to. VS: T 37.0, HR 76, BP 142/86, RR 16, SpO2 97% RA. The remaining exam proceeds without acute findings.""
Clinical Context
Common H&E general appearance shorthand: WDWN = well-developed, well-nourished (normal nutritional status). NAD = no acute distress (no respiratory distress, no pain behaviors, no obvious acute pathology on inspection). AAOx3 = alert and oriented to person, place, time (sometimes x4 = person, place, time, situation). WDWN/NAD/AAOx3 together signal a stable baseline appearance. Distinction from related phrases: "ANAD" or "in acute distress" — the opposite; "in mild/moderate/severe distress" — gradations when there is distress but not full code situation. Documenting NAD does NOT mean the patient is medically well — a patient with stage 4 cancer can still appear well at the moment; NAD describes the snapshot, not the disease burden. Use in initial encounter documentation and in progress notes when re-examining. Medicare/billing: documenting general appearance is required for E/M coding; NAD is acceptable.
