P07 KE-P07 · outpatient visit

One row per condition family: what the record supports under the published definition, what the note states, the visit's diagnosis entries, and an assessment. Codes are coded from the signed documentation; the software never assigns one.

COPD airflow obstruction grade by post-bronchodilator spirometry (GOLD 2026)

gold2026_copd_airflow@1.0
In patients with COPD (FEV1/FVC < 0.7): GOLD 1: Mild FEV1 ≥ 80% predicted; GOLD 2: Moderate 50% ≤ FEV1 < 80% predicted; GOLD 3: Severe 30% ≤ FEV1 < 50% predicted; GOLD 4: Very Severe FEV1 < 30% predicted

Contested: The fixed ratio 0.7 is contested against the lower limit of normal (z-score) approach used by ATS/ERS interpretation standards (not opened); the fixed ratio over-diagnoses in older and under-diagnoses in younger adults.

Not encoded: COPD also needs the appropriate clinical context (symptoms, exposures); the grade describes airflow obstruction only and never says COPD is present. Symptom and exacerbation assessment (GOLD ABE groups, mMRC, CAT) is not encoded. Pre-COPD and PRISm are not encoded. Whether the test was post-bronchodilator is asserted by the sender through the analyte name.
